Ferroelectric memristors may lead to brain-like computers
Sodium-air battery offers rechargeable advantages compared to Li-air batteries
Graphene enhances many materials, but leaves them wettable
Graphene is the thinnest material known to science. The nanomaterial is so thin, in fact, water often doesn't even know it's there.
Research team develops tattoo-like skin thermometer patch
Researchers unravel mysteries of spider silk
(Phys.org)—Scientists at Arizona State University are celebrating their recent success on the path to understanding what makes the fiber that spiders spin – weight for weight - at least five times as ...
Artificially-engineered material pushes the bounds of superconductivity
A multi-university team of researchers has artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications.
Nanotrees harvest the sun's energy to turn water into hydrogen fuel
(PhysOrg.com) -- University of California, San Diego electrical engineers are building a forest of tiny nanowire trees in order to cleanly capture solar energy without using fossil fuels and harvest it for ...
Merging bioengineering and electronics: Scientists grow artificial tissues with embedded nanoscale sensors
A multi-institutional research team has developed a method for embedding networks of biocompatible nanoscale wires within engineered tissues. These networks—which mark the first time that electronics and ...
Engineers develop a stretchable, foldable transparent electronic display (w/ Video)
(Phys.org) —Imagine an electronic display nearly as clear as a window, or a curtain that illuminates a room, or a smartphone screen that doubles in size, stretching like rubber. Now imagine all of these ...
Making a better invisibility cloak
The first functional "cloaking" device reported by Duke University electrical engineers in 2006 worked like a charm, but it wasn't perfect. Now a member of that laboratory has developed a new design that ...
Mix of graphene nanoribbons, polymer has potential for cars, soda, beer
A discovery at Rice University aims to make vehicles that run on compressed natural gas more practical. It might also prolong the shelf life of bottled beer and soda.
New mechanism converts natural gas to energy faster, captures CO2
(Phys.org) —North Carolina State University researchers have identified a new mechanism to convert natural gas into energy up to 70 times faster, while effectively capturing the greenhouse gas carbon dioxide ...
