Researchers Turn Wasted Heat Into Power

Yale University engineers have developed a new technology that makes energy from the low-temperature wasted heat produced by industrial sources and power plants. It is estimated that recoverable waste heat in the U.S. alone could power tens of millions of homes. Although existing technologies can reuse high-temperature heat or convert it to electricity, it is […]

MIT Develops Tough Hydrogel Hybrid

MIT engineers have developed a method to bind gelatin-like polymer materials called hydrogels and elastomers, which could be used to make artificial skin and longer-lasting contact lenses. If you leave a cube of Jell-O on the kitchen counter, eventually its water will evaporate, leaving behind a shrunken, hardened mass — hardly an appetizing confection. The […]

A New Way to Turn Electricity Into Light

By slowing down light to a speed slower than flowing electrons, scientists have developed a new way to turn electricity into light. When an airplane begins to move faster than the speed of sound, it creates a shockwave that produces a well-known “boom” of sound. Now, researchers at MIT and elsewhere have discovered a similar […]

MIT Engineers Search for a New Formula for Concrete

Engineers from MIT are seeking to redesign concrete by using bones and shells as blueprints for a stronger, more durable concrete. In a paper published online in the journal Construction and Building Materials, the team contrasts cement paste — concrete’s binding ingredient — with the structure and properties of natural materials such as bones, shells, […]

A Newly Designed Digital Rochester Cloak

While the Rochester Cloak relied solely on lenses, a newly developed system combines a different type of lens array combined with a digital scanning and processing technique that increases the range of angles for which it works. The Rochester researchers have shown a proof-of-concept demonstration for such a setup, which is still much lower resolution […]

Researchers Create Perfect Nanoscrolls

Using both low- and high-frequency ultrasonic techniques, scientists have fabricated nanoscrolls made from graphene oxide flakes. Water filters of the future may be made from billions of tiny, graphene-based nanoscrolls. Each scroll, made by rolling up a single, atom-thick layer of graphene, could be tailored to trap specific molecules and pollutants in its tightly wound […]
