A new way to analyze how coatings of tiny particles alter the properties of transparent plastic could help researchers create lightweight windows with nearly the strength of glass. The same method could also lead to high-strength, scratch-resistant coatings that could be applied to many different materials, according to the MIT researchers who developed the analysis.

A vascularized fiber-reinforced composite material. Illinois researchers developed a class of sacrificial fibers that degrade after composite fabrication, leaving hollow vascular tunnels that can transport liquids or gases through the composite.

Graphene, a sheet of carbon only a single atom thick, was an object of theoretical speculation long before it was actually made. Theory predicts extraordinary properties for graphene, but testing the predictions against experimental results is often challenging.

If there were a Hall of Fame for materials, manganites would be among its members. Some manganites, compounds of manganese oxides, are renowned for colossal magnetoresistance – the ability to suddenly boost resistance to electrical conductivity by orders of magnitude when a magnetic field is applied – and manganites are also promising candidates for spintronics applications – devices that can manipulate electrons according to their quantum spin as well their charge.

MIT and Harvard researchers are developing a synthetic material to revitalize damaged vocal cords. The team led by Langer and Zeitels has now developed a polymer gel that they hope to start testing in a small clinical trial next year. The gel, which mimics key traits of human vocal cords, could help millions of people with voice disorders — not just singers such as Andrews and Steven Tyler, another patient of Zeitels’.
