Moving beyond semiconductors for next-generation electric switches

Computers use switches to perform calculations. A complex film with "quantum wells"—regions that allow electron motion in only two dimensions—can be used to make efficient switches for high-speed computers. For the first ...

Researchers make thinnest plates that can be picked up by hand

Scientists and engineers are engaged in a global race to make new materials that are as thin, light and strong as possible. These properties can be achieved by designing materials at the atomic level, but they are only useful ...

One step closer to artificial photosynthesis and 'solar fuels'

Caltech scientists, inspired by a chemical process found in leaves, have developed an electrically conductive film that could help pave the way for devices capable of harnessing sunlight to split water into hydrogen fuel.

Surface properties command attention

Whether working on preventing corrosion for undersea oil fields and nuclear power plants, or for producing electricity from fuel cells or oxygen from electrolyzers for travel to Mars, associate professor of nuclear science ...

Lateral crystal growth using oxide nanosheets as seed crystals

In the demonstration project for practical application at the Kanagawa Academy of Science and Technology (KAST), the research group led by Dr. Tetsuya Hasegawa developed a method for growing high-quality oxide thin films ...

Super-stretchable yarn is made of graphene

(Phys.org) —A simple, scalable method of making strong, stretchable graphene oxide fibers that are easily scrolled into yarns and have strengths approaching that of Kevlar is possible, according to Penn State and Shinshu ...
