Batteries are already a familiar part of everyday life-
laptops, cell phones, cars-the objects we cannot imagine life without depend on batteries, but what if the battery was the real invention, the real novelty? Current battery research might pave the way for fast recharging batteries, which might make the electric car available, which would remedy environmental and economic issues involved with the gasoline car. Also, imagine having a cell phone or laptop charge in mere seconds.
A company from the UK, Affresol came up with an alternate solution when it comes to building houses. What strikes me the most interesting about this is it's solution for creating efficient housing that it as cost effective. The company has taken raw material waste, that would eventually end up getting buried in a landfill, an has turned it into something durable. They called the selectively compressed waste Thermo Poly Rock (TPR). It withstands rain, it is fire retardant, and most importantly is much stronger than concrete.
Caltech Materials scientist, Marios Demetriou with his colleagues has recently created a glass that is much stronger and tougher than the best performing steel in the market. Since Ceramics' and Metals' properties are mutually exclusive, Demetriou devised a way to form a new product that would be twice as strong and tough as steel. He melted and combined 2 and more metals like Palladium and Silver and then rapidly cooled them such that the atoms aligned themselves in the manner resembling that of a glass. This new glass although has better properties than that of Steel, it is just equally expensive. Due to the use of expensive metals like Silver and Palladium, this new brand of a "Metallic Glass" is 1000 times more expensive than an ordinary steel. However, the scientists are researching and trying to combine cheaper alloys and metals to form stronger metal glasses considering the range of uses it is being expected to offer. This kind of a Metallic glass, Demetriou says can be used in vehicles and airplane parts that would make them dent resistant.
Rechargeable lithium-ion batteries are now recreate to heal themselves by improving the life span and safety. Professor Scott White form the University of Urbana Champaign found out a way to let the battery to fix the damage itself by embedded tiny microspheres inside the graphite of an anode in order to counteract the cracking of the battery. For the safety of energy-storage technology, professor White developed a microsphere made of solid polyethylene, which is an inexpensive and widely available plastic, to prevent conflagration. This feature would add a greater chance of emerging the market for the electric cars.

This article was about how engineers at The Boeing Co. are figuring out ways to recycle their plane, 787 Dreamliner, which will probably be recycled in 30 years.
The materials used in Boeing 787 are strong and dense with few voids because the fibers all point in the same way with little air space between them. So recycling them means to tease apart the carbon fibers from the resin matrix and align them well enough again in water baths to be reusable again. However not only the recycled materials not as strong as the new materials, but they are very expensive to make.
But once reduction in cost of recycling is solved, there is a very good chance that recycled carbon from retired Boeing 787 Dreamliner will be used to make interior structures of future planes.

The LED yarn is a combination of light-emitting diodes and fiber, producing a material that is soft and waterproof. The yarn can be incorporated into traditional Chinese costumes, which will flash and are suitable for thespians performing at various religious festivals.
Helmets and pads are used to protect people from injuries. The impact energy is distributed throughout the protective equipment to reduce the impact on the person. d3o is a polymer based material that is further enhanced by chemistry. This makes it lightweight, flexible, and more absorbent than other materials. Basically the way it works is that the molecules are free flowing so the material is soft and flexible. But when there is an impact the molecules come together and form a strong bond which hardens the material and allows it to absorb more energy. The material is used in a variety of products.

Over the past decade, there has been extensive research on creating both biofuels and alternative forms of energy. Up until now, biofuels, which are derived from our food source, have been the front runner as the most feasible option. It is not because we cannot artificially convert CO2 and other forms of energy into carbon fuels, which then can be refined into ethanol and other fuels, but simply because biofuels have been the most efficient alternative source due to the fact that they consume the least amount of energy while being created. Well, that may all come to a change now due to the work by University of Illinois Prof. Paul Kenis along with his colleagues at the start-up Dioxide Materials in Research Park. In short, they have found a new and innovative way to artificially photosynthesize carbon fuels, which can be refined into ethanol and other fuels, while using a much smaller amount of energy than previous methods. They utilized a novel ionic liquid to catalyze the reaction. This technology has tremendous potential if it can be done a larger scale due to the fact that our alternative forms of energy will be able to be derived artifically rather than from our food source. More importantly, technology at UIUC is once again changing our world one step at a time.

Being a softball player the newest technology and advancements have always been something that sparked my interest. In the past 5 years there has been an absolute revolution in bat technology. This is due to the availability of composite materials. They began making bats out of rolled carbon composite and it made it possible to have a lighter bat with more "pop". The advances of adding a composite material made performance better to a point that they ended up having to hinder the bats because the ball could be hit off of the bat at a speed where fielders literally could not physically react in time.
This article is a short biography of Ju Li, a distinguished professor of Nuclear Science at MIT. Li discusses how his focus is manipulating material behavior by applying mechanical stress and high temperature. This reminded me of our classroom about how metals can become brittle if overworked. He has an interest in nanotechnology and has a conducted research on how these materials are affected by extreme conditions as compared to their normal-scale versions. It is interesting to see a relatively young man who is actively engaged in both teaching and furthering the study of material science. Full Article Here
"Great news on the power efficiency front: Scientists have invented a new material that can efficiently convert heat waste in cars, power generators, and heat pumps into electricity. The new material is thermoelectric, and can turn heat into energy without any pollution.
The invention, thallium-doped lead telluride, is twice as efficient as the second most efficient material used in thermoelectric power. The lead telluride creates electric power like a conventional heat engine coupled to an electric generator, but uses electrons as the working fluid instead of water or gas. Additionally, it creates electricity directly.
Most importantly, the material is most effective between 450 and 950° Fahrenheit. This is a typical temperature range for many power systems, including car engines.
Many experts argue that up to 60 percent of a gasoline engine’s energy is lost through waste heat, so a thermoelectric device using lead telluride would be a welcome addition to any car. Such devices have no moving parts; this means that wear and tear is virtually non-existent.
Research project leader Joseph Heremans of Ohio State University is optimistic about the future of thermoelectric nanotechnology---he hopes to boost the efficiency rating of the new material by a factor of two. For now, though, we can be content with the incredible new technology created by Heremans and team.
There is a new material that can convert heat energy into electricity called thermoelectric. It has so many possibilities and potential to save energy that we use and waste everyday. Also more products could be invented and developed through this material into a whole different level .While we heavily depend on electricity and other energy sources, it is good news that we have found an alternative option to live more efficiently.
Ford Motor Co. and Scotts Miracle-Gro Co. are looking into ways to use the leftover coconut husks from Scotts’ production to be made into a composite reinforcement for plastics. Scotts’ uses the coconut husks’ fibers in the soil and grass seed products. This will help to eliminate some of the more than 70 million pounds of husks per year, something of tremendous value to Scotts’. Also, this would help to eliminate the use of plastic needed in Ford’s manufacturing process and make for a more natural look for the reinforced parts.I though this was an interesting article as it shows how industries can form a profitable relationship while still helping the environment. It will be interesting to see what comes of this and if there are more industries that will pair up in such an ecologically friendly way.
DEARBORN, MICH. (Oct. 6, 3:05 p.m. ET) -- Ford Motor Co. is continuing its research into the use of natural fibers and bio-based plastics, this time investigating the use of coconut husks as a composite reinforcement.
Ford and yard and garden company The Scotts Miracle-Gro Co. are looking at uses for coconut husks -- or coir -- left over from Scotts’ existing production operations.
“We’re taking a material that is a waste stream from another industry and using it to increase the sustainability in our vehicles,” said Ellen Lee, technical expert for plastics research at Dearborn, Mich.-based Ford in an Oct. 6 news release.
Ford already has used wheat straw as a filler in door trim bins, uses a soybean oil-based urethane foam blend in seats and castor oil blend for instrument panels.
Scotts Miracle-Gro, based in Marysville, Ohio, uses coconut husks’ fibers as a carrier in soil and grass seed products. The fiber holds more water in the potting soil mix than soil alone, allowing gardeners better water release control in their plants.
Scotts uses more than 70 million pounds of husks per year, and teaming up with Ford would be a potential high value use for its leftover material, said Dave Swihart, senior vice president of Scotts’ global supply chain.
Ford plans to research the use of the husk as reinforcement in plastic parts, which would reduce the amount of plastic needed and lighten part weight. Visible natural fibers would also provide a more natural look to reinforced parts than traditional fillers, the company said.
An Italian sugar producer may be at the forefront of one of the newest advancements in bio-plastics. Co.Pro.B, Italy’s largest sugar producer, has a factory located in northern Italy. Bio-on, a small company with offices near the plant, has had a growing interest in the sugar beet molasses that leaves the plant as trash. Bio-on has been performing research over the last five years to develop a way to turn this molasses into plastics.
Through a process of mixing the sugar beet molasses with bacteria which feed on the sugar in a fermentation process that creates lactic acid, filtrates and polymers that can be used in the production of a biodegradable plastic called PHA.
I found this article to be interesting as it relates to MSE 101 as plastics are polymers. It also made me think of how agricultural byproducts can be used in composites, as in the Re_Home's exterior siding. However, here it is used to create a bio-plastic.
Almost everyone knows about the tragic terrorist attacks involving the World Trade Center on September 11, 2001 and how they have affected many lives. The security of nation has been on higher alert ever since too prevent such tragedy. The collapse of the two towers were said to be the cause of over heated steel beams. A new theory revolves around the explosions that were heard just before they started to collapsed. A scientist came up with the theory that the meeting of molted aluminum from the planes and water creating the explosions. This sparks engineers to make planes that include metals with higher melting points to prevent the the metal alloys from over heating. As we learned in materials class, such decisions of material choices could save many lives.
The genetic makeup of two heat-loving fungi, Myceliophthora thermophila and Thielavia terrestris have been decoded by scientists and will soon play role in energy and material science. These two fungi are often found in composite, also are self-ignite without spark or flame.Organisms that thrive at high temperatures are rare. Fewer than 40 heat-loving fungi have been identified and they hold great promise in the production of many chemicals and biomass-based fuels. These two fungi, however could accelerate the breakdown of fibrous materials from plants at temperatures ranging from 40 to 70 degrees.
Scientist says that their next goal is to figure out how these organisms flourish at high temperatures and what makes them so efficient in breaking down plant materials.
And that will transit our world from a heavily fossil-dependent economy to a biomass one.
Are the days of refs making wrong calls over? Some might say so if the CTRUS football (soccer ball) becomes a reality. The CTRUS football, coming in multiple designs, incorporates multiple technologies to enhance the fairness of the ‘beautiful game’. The designs features transparent footballs that contain an interior processor and GPS positioning that allow the ball to light up when crucial plays occur. This eliminates the age-old issue of refs calling the ball out when it is still in play. This advancement in soccer represents a clear relation to materials in today’s world. The materials incorporated in this football that allow transparency yet durability, electronic positioning, and most importantly, it is created using materials that allow it to function without requiring air to pump it up. These features will certainly propel the game forward.

It is estimated that 2.6 billion people who don't have regular access to toilets. Again, 2.6 BILLION PEOPLE. Lack of access to toilets poses huge risk in contracting diseases spread through watershed in urban slums across the world. Often, those without access to a porcelain toilet use helicopter toilets, or plastic bags of excrement that a slum-dweller may fling away. However, as far as you think you can throw a bag, you cannot throw it out of your watershed. Meaning, that current methods of disposing of waste pollute the entironment and encourage the spread of disease.
The Solution? The Peepoo. This bag, "once used, can be knotted and buried, and a layer of urea crystals breaks down the waste into fertilizer, killing off disease-producing pathogens found in feces." Not only does this bag provide a way to dispose of waste in a sanitary way, but it can also be used to fertilize crops.
There are world-altering implications that come with the introduction of the Peepoo to growing, third-world countries. Clever use of materials can provide worldly sanitation and fertilization and prove to make 2.6 million lives a little bit better.
2011 has brought us so many new inventions, but one of the coolest ideas I've seen has been the Flying Car which is now being developed and distributed. It relates to MSE because it is using present materials to create something completely new and innovative. The flying car can drive on streets and has highway speeds, but if you need it, it can also fly you to wherever you need to go. It uses unleaded gas and seems very practical. This is some of the best usage of materials I've seen because the idea is simple but it actually does make a lot of sense. Flying to places instead of driving is probably easier and quicker. Who knows, maybe in a couple years we will all be driving and flying with these awesome cars!
Dow Chemical claims that they have found a way of making plastic out of sugar cane, which is as cheap as making plastic out of petroleum. The company plans to build a plant in Brazil that it says will be the world's largest facility for making polymers from plants. Cirihal says Dow is keeping costs down by doing every part of the process, from growing the sugarcane to producing the polymers. This makes it possible, for example, to provide energy to run the plant with biomass left over from producing sugar from sugarcane. While he says the plastics produced will be competitive with petrochemicals, he also says the company hopes to charge more for the product because of the significant demand for low-carbon, sustainable materials.
Using calcite prisms, a type of natural occurring crystal, research teams have been able to create "carpet cloaks." These carpet cloaks can take objects as big as an ant and make it disappear. On the website, there is a picture of a piece of paper that has been cloaked. In the creation of this, the research teams used calcite prisms for the first time to make a cloak devise. In the past, metamaterials have been used. http://www.sciencenews.org/view/generic/id/69415/title/Invisibility_cloaks_hit_the_big_time
PUMA "CLEVER LITTLE BAG" Shoe Box
This new idea of a shoe box went the other way of creating something productive. It gives shapes and reduces the cardboard use by 65%. Moreover, without that shiny box exterior, there's no laminated cardboard (which interferes with recycling). There are things that regular shoe boxes contain, but not the new Puma Clever Little Bag such as: There are no tissue papers inside. There are no throw-away plastic bag. The bag itself is made of recycled PET, and it's non-woven; woven fibers increase density and materials use; and stitched with heat, so that it's less manufacturing intensive.
The impact: Puma has many great benefits:
Puma estimates that the bag will slash water, energy, and fuel consumption during manufacturing alone by 60% in one year:
- Savings of 8,500 tons of paper
- Saves 20 million mega joules of electricity
- Saves 264 gallons of water
- Ditching the plastic bags will save 275 tons of plastic
- The lighter shipping weight will save another 132,000 gallons of diesel
- Saves 264,000 gallons of fuel
This Product relates to MSE by creating many ways to use materials and try to make them better for the world. As an Industrial Designer I believe its important to think how we use materials and how we use "less" to make it better for the world. The innovation of this Clever Little Bag is a great Idea in the shoe manufacturing process. This bag isn't going to save the whole world, but it's a nice reminder that there are still plenty of ways we can improve everyday things.

Just like ordinary concrete surfaces, it looks a tad dull and drag when dry … but put it in a place with condensation-producing heat, running water or natural rain and it reveals hidden decorative designs (that disappear again as it dries).
Conceived by Frederik Molenschot and Susanne Happle, it is a bit like the old bathroom mirror trick – the writing, picture or pattern appears and disappears with moisture content. On a humid day you might get partial glimpses of what would be fully visible during a torrential downpour.
Floral patterns and falling leaves conjure images of sidewalks and steps where organic matter fell before the poured concrete fully dried, but the possibilities beyond that are endless as well – spirals of words in your bathroom sink, interactive decor in public places, steamy subliminal messages in urban night clubs or remote saunas.
While custom and cast-in-place patterns are possible, prefab repeating modules make this a store-shelf-ready concept just waiting to enjoy mass production and commercial distribution.
WIth their new product line, Sanjay Jha, CEO of Motorola Mobility Holdings, Inc., has revealed that Motorola plans to issue smart phones with kevlar parts and body frames. This would be a huge improvement to the previous ceramic and metallic body type that is typical of Motorola Droids as it would be much stronger of a material.
Kevlar phone bodies would allow for smart phones to sustain high levels of stress and damage before actually breaking or deforming. This is wholly dependent upon what type of composite is used and how it is formed and woven. Kevlar is not molded, but spun in a very intricate process to remove all air pockets and create an extremely solid material. When spun properly, it can produce a tensile strength of 3.620 MPa.
Another reason as to why Kevlar is so strong is its inter-molecular hydrogen bonding. Molecules will bond together using h-bonding between the carbonyl and nitrogen subgroups. The spinning process of Kevlar also eradicates any impurities such as air bubbles and various salts, two components which could drastically compromise the strength and structure of the final nylon sheet.
With the tensile strength that a kevlar body offers, Jha predicts composite materials is where the future of phone design is going.

New technological developments in the field of polymer strength is being incorporated by Rawling's in new NFL football helmets. The research was developed at The University of Southern Mississippi in the school of Polymers and High performance materials. The material will help reduce the impact of the collision, and it is allowing a new audience to see how different materials affect the way we live.
Recently, 3M has developed a way to make windows into solar panels without reducing the visibility.
Meaning, one can still look out the window; it's a transparent solar panel!
The way it works is it's a thin film that you put on your windows that anybody can do.
It'll apparently be very affordable in comparison to solar panels, but it will only generate 20% of what a normal solar panel can produce, which isn't bad.
Like the Re_home, it's dealing in electronic materials that will help utilize future technology.
This material is used in electronic products, but it takes a lots of time and effort to produce. Most of the time if the silicon evaporates too much it becomes useless and cannot be used in the electronic products. Scientists have figured out a new effective way to prevent the evaporation. This relates to material science because one of the goals of material science is to find new ways for materials to be more effective.http://www.sciencedaily.com/releases/2011/09/110922180029.htm^ ^ http://www.sciencedaily.com/releases/2011/09/110922180029.htm
A key problem electric car manufacturers are having is finding a light weight, powerful, and safe battery. The more light weight an electric car is, the more eco-friendly and efficient the car will be. Average electric car batteries weigh over 100 pounds, and this new battery only weighs 77 pounds. Traditional solutions were made of steel, but thanks to material science, developers were able to make a battery and protective casing with a much lighter composite material.

Jeff Tiedeken's Gravity Bike
The Gravity Bike is designed for a sport activity of riding a peddleless and gearless bike. The idea of riding came from Newton's discovery. The article states, "it has to be low to the ground and fit within a specified weight range." The heavier people most likely to ride faster than the light-weighted people.
The materials were the same materials that the regular bike is made. The brake pads, cables, adapters, wheels, inner tubes, metal and PVC pipes and tubing, and sheet metal and tools. The tires were used the silk road tires so the ride is smooth and fast. The angle of head tube is changed, and the length of it is also shorter.
Organic Light-Emitting Diodes (OLEDs) are solid-state devices composed of thin films of organic molecules which generate light when electricity is applied. OLEDs are semiconductors that are only 100-500 nanometers thick, and they are able to produce superior visuals when compared to conventional LEDs and LCD. OLEDs typically contain 2-3 layers of organic materials and create light through a process known as electrophosphorescence. There are several types of OLEDs currently available, each with unique properties:
- Passive-matrix OLED
- Active-matrix OLED
- Transparent OLED
- Top-emitting OLED
- Foldable OLED
- White OLED
The first fully stretchable OLED has successfully been created, paving the way towards innovative commercial applications from companies such as Samsung and 3M, who aim to create video displays that can swell, shrink, bend, fold, and more.
A multivascular network materials, capable of pumping self-healing polymers, is created by the Microvascular Autonomic Composites Initiative. The layered structure is capable of heal a crack at the same spot not just once - but even up to seven times. It is pleasing that professors at the Univiersity of Illinois at Urbana-Champaign participated in this project.
As an industrial designer, I find that we are constantly looking for new ways to inspire and be inspired. One source that holds a lot of potential is nature. This article kind of supplements a previous blog post here on biomimicry, or looking at different parts and systems of nature and emulating them to solve human problems. This article includes a gallery of eight different animals and how scientists, researchers, and engineers have applied their unique characteristics in the medical field. Here are two of my favorites:
The sea cucumber's unique skin can change from soft to stiff in an instant as a defence mechanism, inspiring the development of a biopolymer that turns soft when exposed to water and goes back to being rigid when the water evaporates and has the potential to be applied in neural implants.
Probably the most well known of these "lessons" and perhaps the most prominent for out class right now comes from spider silk, whose arrangement is "a mix of hard, crystalline regions and amorphous, elastic regions that give silk fibers their amazing tensile strength and elasticity." Spider silk has lots of applications for military and medical industries including substitutes for Kevlar armor and biomaterials.
Im really interested in sustainable architecture so when I found this article about a phase changing material that can regulated heating with in a homes walls, it sparked my interest. The article expalins "An inch of phase change material has the same heat storage capacity as a foot of concrete. Adding it to walls can reduce the amount of heat that naturally enters a building by 40 percent and energy consumption by 20 percent, depending on the building's location. The material functions kind of like a high-tech adobe, keeping interior temperatures comfortable throughout the day and night." I believe that this phase changing material would be considered to be an new form of composite building material. Read more at ... http://news.discovery.com/tech/smart-walls-keep-house-comfy.html
This video, "made possible by Corning", depicts a conceptual day in future where our entire day's activities are accomplished by highly interactive glass. With our current advancements in touchscreen technology and the already available magic glass mentioned in an earlier post by another student, "a day made of glass" is not completely impossible. but I still find it highly unlikely as the all the concepts seem to completely disregard the very much visible electronics that would be necessary under all that beautiful clear glass. And, ultra thin, rollable, electronics enabled glass? Amazing but, possible? Also, glass is very susceptible to fingerprints and cracks so I'm not sure I want my entire life to be based on such a delicate material. Regardless, it is a wonderful concept built upon an everyday material and I found myself drawn to all those amazing possibilities because I am all for technology.
New properties of Graphene (nanomaterials)-- It is the thinnest material in the world that is a single atomic layered material made by reacting graphite powers with strong oxidizing agents. Many scientists have been interested in graphene oxide because they think it could help to produce low cost carbon-based transparent and flexible electronics. However, the scientist found the new insight of a property of graphene oxide that could lead to new applications for the materials which means that it could help to disperse insoluble materials by using its conductivity.
Scientists at the University of California at Berkeley have developed a glass material that mimics the anisotropic structure of natural materials. The new bioactive glass scaffold aids the regeneration and self-repair of bone defects. This material has improved upon past designs of biomaterial metals which do not allow for bone regeneration and snug fitting. New opportunities have been created by this new ceramic in terms of bone regeneration. (a gel example from http://elements.geoscienceworld.org/cgi/content/full/3/6/393/FIG4)
Basically what this does is that it takes water and splits it into hydrogen and oxygen. That is stored in a fuel cell and when the energy is used, the waste product is just water.This tech has potential because it can be more easily mass produced then similar ideas.
The way it works is that sunlight generates a current in the semiconducting silicon, "coated on one side with a special cobalt catalyst and the other nickel-molybdenum-zinc alloy" in order to split the molecules in the water. The relevancy is that its an idea that takes these materials that are more applicable in the market as opposed to being a tech that is too expensive to produce for global needs. Other websites also propose the idea that the "waste" could be a solution to freshwater issues. The tech is still in its infancy and not ready for replacing gas anytime soon.
This article is about a new way of classifying molecular structures using a math trick of reversing spirals. After our discussion in class about crystalline structure and defects, we learned that the way a material is structured affects its properties. This different symmetry idea can help explain materials' properties even further and help everyone understand as much as they can about different materials.
The new technology from Dow Coating Materials called EVOQUE pre-composite polymer technology provides pain that uses 20 percent less TiO2. TiO2 is a scarce and costly mineral for most white and light colored paints. This article discusses the new technology and materials, and how they relate to consumer cost and manufacturing cost. This new technology has had positive outcomes and paint maybe changed to have a standard of EVOQUE. This article relates to MSE 101 because it discusses a polymer material that has changed the way certain paint has been manufactured and distributed. It is also a new technology combining a pre-composite material and polymer. This can change the way paints are sold and made.
When we talk about biomaterial The following words come up in our mind must be hi-tech, but the real biomaterials are usually come from living things among us. In material science, we should not just creat material, we also need to find new materials. And This article is a good example of how can we find the solution from normal plants and use them to creat new material. This new material called SLIPS, which is come from Pitcher plants, but it is both more slippery than the natural pitcher plant material and also more slippery than any artificial material and following images just showed its strong property. That unlike most other materials this cool, it's easy to make.
Located at 30 St Mary's Axe, London, United Kingdom, Swiss Re building is definitely one of the most distinct landmarks in London.
This bullet-shaped building is, out of my imagination, London’s first ecological building due to its “energy-conscious enclosure” design, which resolves walls and roof into “continuous triangulated skin.” This design also allows column-free floor space, and more light and views in the building.
Environmentally, the shape of the building effectively “reduces the amount of wind deflected to the ground compared with a rectilinear tower of similar size.” In addition, the halls between each radiating shaped floor link together vertically for a “series of informal break-out spaces that spiral up the building.” Interestingly, this system lowers tower’s reliance on air-conditioning. It is expected to use only half of the energy that consumed by a typical air-conditioned office building.
Indeed, the design and the shape are really the tow main factors that make this building interesting, and it requires picking the appropriate materials that can meet the design, I think this building is conceptually innovated on its design and materials.
I think this article is pretty cool. It explains that this material called "Meta-material" produces what's called negative refraction of visible light. This means that this material takes the light and bends it in the opposite way that it is supposed to when passing through a material. At first they were only able to accomplish this with 2-d materials, but they now have a new multi layered "fishnet structure" that they claim allows us to "harness light at will". I'm looking forward to seeing the advancements with this "meta-material". For more info, go to http://www.livescience.com/2767-material-objects-invisible.html
Scientists have been modifying semi conductors to create a 'topological insulator' which would enable creation of a quantum computer.This model is a huge sep forward in this field as compared to its previous designs and models. It is a huge breakthrough as Quantum computers potentially are a thousand times faster than today's computers. Quantum computers use a fraction of the resources of a regular computer but deliver more than a thousand times their speed. Thus this is a huge leap for mankind.
The article focuses on a new breakthrough developed by Professor Gadi Rothenberg and Dr. Albert Alberts. The experts created a completely biodegradable and recyclable resin that is non-toxic and completely non-hazardous. Previously, resins were normally made through hazardous means - burning fossil fuel under extremely strict precautions. These synthetic resins are mainly used in the construction industry. This article is extremely applicable to our class, MSE 101. One of the main goals and focuses of MSE is the use of efficiency and environmentally friendly materials to create products. The biodegradable and recyclable resin discussed in the article match this description. Also, resin is commonly used in polymers, plywood, and concrete (materials commonly studied in MSE).
I found this article the other day and found it to be very interesting. The article discusses how an artificial vascular system is being developed so that materials can be self-healing. It works kind of like epoxy but on a much more microscopic scale. This may allow for longer lasting materials in the future, as they will "fix" themselves and repair cracks and fractures on their own, much like our own biological systems. Sottos and White, faculty in the College of Engineering at the University of Illinois, and their fellow collaborators from Beckman's Autonomous Materials Systems (AMS) group developed different methods for self-healing. They found that an active pumping mechanism in a microvascular system is the most effective but is not yet possible for the material to do that on its own. Hopefully in the future that may be possible.
Within the past year, there has been innovative accomplishments in the construction industry. Researchers at the University of Sheffield and EU partners have formulated a new form of concrete that provides many different benefits. Concrete is an example of a composite. As we learned in class, a composite is a mixture of two or more materials into a single component. According to the article, the new roller-compacted concrete, "consists of dry mix concrete reinforced with recycled steel fibres from waste tyres." Some of the advantages of this composite is that is much cheaper than concrete and able to facilitate traffic much quicker than regular asphalt or concrete following being laid. Composites are typically expensive, as stated in lecture, so the fact that the researchers are able to lower the material's price is remarkable.

As we have learned throughout a significant portion of our lives, a window does not differentiate where a ray of light originated from. However, we now have reason to believe that special types of glass and plastics may be able to distinguish the direction of the light. The phenomenon lies in nonlinear materials. The Italian physicists state that this material could block light from one direction while simultaneously allowing light to pass through from the appropriate direction. Nonlinear materials can change as light passes through them. The light changes the properties of the materials as it passes through the object. This ultimately determines and even changes how the light behaves. This research is applicable to MSE 101 because the knowledge integrates physics and engineering. Also, their work attempts to understand the structure and properties of the nonlinear materials and how these factors affect performance. The scientists are hoping to determine how to develop wave diodes that only allow waves that flow in a certain direction. If you are interested in reading more, please check out the following link:

Graphene is basically a monoatomic thin sheet of graphite (the very same graphite used in pencil lead) made of fullerenes and carbon nanotubes. The more impressive application of this thin material is its strength and conductivity. It is said to be the most conductive material ever found on earth. This is an absolutely great material for electronic components such as processors, IC chips, etc... Considering how thin graphene can be, it has sparked many ideas of ultra thin computers and touch screen devices. Not to mention, its strength is also unprecedented: it is 200 times stronger than structural steel according to the article. The article even put its strength into prespective: "it would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap [cling film]". This could be the future of electronics and could make silicon obsolete in the semiconductor industry.

As I was looking for an interesting material to talk about in my blog I ran across the magazine, Materials Today. So I decided I would take the time to introduce everyone to the magazine. If you want to learn anything new about materials, or old even, this is the perfect place to look. It has articles on the website even divided up by class of material, such as biomaterials, ceramics, composites, etc. So if you want information about just a particular class, this is the best place to go for interesting articles. I was using the website to try and find something interesting and found too many options! I hope you enjoy the website as well!

Heat is typically a waste byproduct created when using electrical devices, such as a car. By using a microwave oven to cook a nanomaterial made of aluminum and zinc oxide, researchers have discovered a way of harvesting heat waste and converting it into electricity. This would allow for greater efficiency in devices that create heat and ultimately reduce our dependency on fossil fuels.
Material Science plays a significant role here as researchers searched for a material that is good at conducting electricity but poor at conducting heat. Normally, conductivity with electricity and heat are directly related, so it is a challenge to decrease one but not the other. However, by adding aluminum to the zinc oxide and processing the material in a microwave oven, researchers were able to do it. The method is fairly inexpensive and is environmentally friendly. This opens the door for other researchers to come up with creative ways to increase our overall energy efficiency by using energy from heat waste.

Due to a large concern for the safety of baseball players, the NCAA and NFHS (National Federation of State High School Associations) have changed from a BESR standard to a stricter BBCOR standard for non-wood baseball bats. BESR is known as ball exit speed ratio, and BBCOR is known as batted ball coefficient of restitution. Basically, metal bats were too powerful and were providing extra "pop" due to their innate properties. They were proven to be more effective for hitters than wood bats. Metal bats provide more "pop" because they are lighter (easier) to swing, and they have greater elastic properties than wood bats. This extra "pop" in metal bats was putting fielders at risk because baseballs were entering the field of play at faster speeds and at a higher frequency. The notion behind switching to this stricter BBCOR standard is to make metal bats more similar to wood bats in terms of how hard and how often baseballs are hit into the field of play by batters.

In this class, I think that we focus a lot on items made from materials for the future. We look at carbon fiber bikes and technology made from spider silk. This is why I felt the need to post a blast from the past that has been given new life. Artist, Jane Walentas has spent the past 20 years working on a project that many of us could have only dreamed of as children. She has been restoring the DUMBO, a carousel from Ohio for the Brooklyn Bridge Park. This carousel was even decorated gold leaf and hand painted and adorned with an acrylic box. It looks almost as though it is being preserved in it's crystal clear box, however the carousel open on September 16 and is to stay open year round.

Can a flexible LED placed on the human heart, brain, or blood vessels diagnose or even treat various diseases? New research suggests these possibilities may soon become a reality.
A team of researchers in South Korea led by Prof. Keon Jae Lee (Department of Materials Science and Engineering, KAIST) has developed a new concept in cancer detection: a biocompatible, flexible gallium nitride (GaN) LED that can detect prostate cancer.
I found this article interesting because the product relates to both electronic and biomaterial properties. The research team has taken GaN LEDs, used in LED TVs, and developed it into a biocompatible material that can be used in human bodies to detect cancer.

Since technology is a part of our everyday lives I thought this was an interesting topic. Copper nanowires could replace the existing indium tin oxide(ITO) films. The copper nanowires are transformed into transparent conductive films and coated onto glass or plastic. Found in the display screens of cell phones, IPads, and electronic readers, replacing ITO with copper could lower costs. The copper is less expensive to manufacture, whereas Indium is an expensive rare earth element. Duke chemist Ben Wiley who developed this technique co-founded a company called NanoForge Corp in 2010. "In early 2011, NanoForge received a $45,000 North Carolina IDEA grant for refinement and scale-up of the manufacturing process of copper nanowires, and it is now filling orders."

Although we have learned about silicon as an electronic material, Silicon also has many applications in kitchen tools and appliances. It has several important properties such as flexibility, durability, and heat stability. This translates to many convenient uses in the kitchen. For example, utensils made from silicon like spatulas can bend like plastic or rubber, yet can be used directly on a hot pan. Additionally, baking pans made from silicon don't require greasing or flouring, and can be transferred directly from the oven to the fridge or freezer without breaking or warping, unlike glass or metals. For manufacturers, silicon easily can be combined with fillers or pigmentation, and can be used in a wide variety of temperature settings.
This material is important in today's world because of the current economy. People eat out less frequently and spend more time (and money) in the kitchen. By taking advantage of more recent kitchen technology compared to what our parents or grandparents might have used, our cooking can become easier and more convenient.

When a pair of basketball shoes upper material thickness of only 1 mm, the overall weight of only 9.8 ounces (equivalent to 27.78 grams) of the time, this is a kind of concept? I thought that the beginning of the 2010 season, Derrick Rose put on the adidas adiZero Rose 1.0 debut, basketball shoes, adidas lightweight revolution has begun to reflect the products and achieve extremely light. But when the playoffs start, adidas top basketball boots adidas adiZero Crazy Light coming when, in fact, the subversion of lightweight basketball shoe has just arrived.
1 mm SprintWeb, not only on technology challenges. Breathable mesh body of the shoe, make your feet dry and comfortable even play a role in the campaign. Clima Cool technology research to bring the data said that if the body temperature from 37 degrees down to 36 degrees, to be able to extend the physical limits of 50% of the time in basketball often means a critical moment in the score, and even the team's victory . Bring a great sense of permeability, adidas adiZero Crazy Light Derrick Rose 9.8 Black White is back on the light wings, 9.8 ounces for a basketball player means faster, better physical domination, and a more powerful explosive.
More than two years in the making, the adidas Innovation Team (aIT) and adidas Basketball Design developed the adiZero Crazy Light from the canvas of a bare foot to ensure every part of the shoe serves a vital performance function. Only lightweight, highly flexible and durable materials were selected to create the lightest shoe in basketball.
“We wanted to build the ultimate shoe for the ultimate basketball player, and research has clearly shown that a lighter shoe will provide better performance,” says Griff Wilson, senior developer, adidas Innovation Team. “The key is to provide the support and cushioning of a traditional basketball shoe in a super lightweight construction. The Crazy Light, the culmination of two years of design, research and testing, is the lightest shoe in the market by nearly two ounces and will give basketball players an advantage over the competition.”
The adiZero Crazy Light features a revolutionary new SPRINTWEB exoskeleton upper less than 1mm thick and seamlessly bonded to a nylon textile base to significantly reduce weight and provide increased support and strength. The web layout of the materials provides vertical and horizontal strength to give players optimum support for any cutting motion.
The SPRINTFRAME external heel counter and TORSION SYSTEM are bonded together to allow maximum weight reduction, energy return and motion control. Each lace eyelet is load bearing and has a corresponding web spar to support players during hard cuts. The upper is made with translucent nylon to further decrease weight and give players nearly 360 degrees of ventilated comfort.
The adiZero Crazy Light traction system has varied engineered thickness to ensure maximum grip in high wear perimeter zones, and less thickness and weight in low perimeter zones like the midfoot. It also features longitudinal grooves in the heel and forefoot to provide support during extreme forefoot cuts.
A 9-story building the EcoArk Pavilion in Taipei, Taiwan is built primarily out of interlocking polymer bricks called Polli-bricks made from recycled PET plastics. It's shape emulates that of a polygonal bottle which allows the material to be snugly stacked together, capable to withstand harsh weather. The bricks are cost efficient, strong, and environmentally friendly. The company that produces these innovative building blocks are also looking into using recycled wood and silicon to create new building materials.

Scientists at Tufts University have found ways to encrypt secret messages (secret agent-style) into genetically engineered strains of E. Coli bacteria. They've produced fluorescent strains of of bacteria that are only viewable under a specific wavelength of light. Currently, there are seven different strains and a unique pair of strains stands for a specific number or letter (Yellow and Green means H, Green and Orange mean I). The encrypted messages are called SPAM:steganography by printed arrays of microbes. While using SPAM for top-secret military missions would be ideal, it will more than likely serve as a way to separate counterfeit drugs from the real thing.

I think the design of this car is so cool. And it could satisfy the creativity and imagination of people. From the Material perspective, It should give a significant contribution to accomplish this design.
http://online.wsj.com/article/SB10001424053111903461304576523851844058530.htmlAnyone who grew up in the 1980s on a diet of Back to the Future and Knight Rider will, by now, be very disappointed in how the car of the early 21st Century has turned out. Cars cannot yet drive themselves, they don't help fearless cops solve villainous crimes and they certainly can't transport the driver to another era.
While this view of the 21st century from the hazy imaginations of the 1980s mind has quite evidently not come to pass, a closer inspection of the latest technology available to drivers reveals that, in some cases, today's technology is not that far off the futuristic fantasies of three decades ago.
Thanks to the World Wide Web, satellites, speech recognition, radar and digital content -- not to mention the smartphone and the tablet computer -- the world has arrived at a point in motoring history where the car is starting to resemble people's childhood imaginings. And it is big business for the beleaguered motor trade, with gadgetry and 'soft' technology increasingly becoming what differentiates a car maker's latest marque from an ever more homogenous store front of vehicles.
'Style, design and fuel economy are still very important, but they are no longer the key differentiators: It's the experimental and technological things that consumers now reach out for,' says Jim Buczkowski, Henry Ford technical fellow and director, at the Ford Motor Company in Detroit. 'It is certainly an increasing draw to get people onto the dealerships' showroom floors -- especially if they have already tried it.'
So, is the driverless car any nearer to realization? Ford's Mr. Buczkowski doesn't envisage totally autonomous cars any time soon, but plans are on the drawing board. Researchers at the Freie Universitat in Berlin are experimenting with mind technology that could eventually lead to hands-free motoring. Drivers wear a neuroheadset device which interprets electrical signals from the brain with additional support from latest radar sensing technology and cameras. Such technology, however, remains firmly in the realm of science fantasy. Numerous trials have also been undertaken with vehicles festooned with equipment that can just about negotiate a car park. Progress is being made, however, in partial autopilot projects for cars.
German car maker Volkswagen is trialing its Temporary Auto Pilot at the EU research project: Highly Automated Vehicles for Intelligent Transport. TAP allows the car to drive semi-automatically up to a speed of 80 miles per hour (129 kilometers per hour), but always under the driver's supervision.
It relies on a series of cameras and ultra-sound radar sensors that ensure the car stays in lane and is a safe distance from other cars. 'TAP is an important milestone on the path towards fully automatic and accident-free driving,' says Dr. Jurgen Leohold, executive director Volkswagen Group Research. 'One conceivable scenario for its initial use might be in monotonous driving situations, such as in traffic jams or over sections of a driving route that are exceedingly speed-limited.'
Ford has a similar set up, which is already on production cars. It too keeps the car within white lines and a safe distance from the car in front. The sensor technology on some of Ford's latest models also allows the car to parallel park itself, with only some gas inputs from the driver. But again the driver is still ultimately in control.
