'Diamane': Diamond film possible without the pressure
(Phys.org) —Perfect sheets of diamond a few atoms thick appear to be possible even without the big squeeze that makes natural gems.
Stressed out: Research sheds new light on why rechargeable batteries fail
Pity the poor lithium ion. Drawn relentlessly by its electrical charge, it surges from anode to cathode and back again, shouldering its way through an elaborate molecular obstacle course. This journey is ...
Liberating devices from their power cords: New structural 'supercaps' take a lickin', keep on workin'
(Phys.org) —Imagine a future in which our electrical gadgets are no longer limited by plugs and external power sources. This intriguing prospect is one of the reasons for the current interest in building ...
Nanowires grown on graphene have surprising structure
(Phys.org) —When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy.
Phosphorus a promising semiconductor
(Phys.org) —Defects damage the ideal properties of many two-dimensional materials, like carbon-based graphene. Phosphorus just shrugs.
Flexible, transparent thin film transistors raise hopes for flexible screens
(Phys.org) —The electronics world has been dreaming for half a century of the day you can roll a TV up in a tube. Last year, Samsung even unveiled a smartphone with a curved screen—but it was solid, not ...
Engineers advance understanding of graphene's friction properties
(Phys.org) —An interdisciplinary team of engineers from the University of Pennsylvania has made a discovery regarding the surface properties of graphene, the Nobel-prize winning material that consists of ...
A promising light source for optoelectronic chips can be tuned to different frequencies
Chips that use light, rather than electricity, to move data would consume much less power—and energy efficiency is a growing concern as chips' transistor counts rise.
Self-cleaning, antireflective coating mimicks the structure of moth eyes
(Phys.org) —Porous films, which use similar properties to those seen in moth eyes in combination with nanoparticles, are being developed into robust, self-cleaning antireflective coatings for use on both ...
New type of solar structure cools buildings in full sunlight
(Phys.org) —A Stanford team has designed an entirely new form of cooling panel that works even when the sun is shining. Such a panel could vastly improve the daylight cooling of buildings, cars and other ...
Trees go high-tech: Process turns cellulose into energy storage devices
Based on a fundamental chemical discovery by scientists at Oregon State University, it appears that trees may soon play a major role in making high-tech energy storage devices.
Understanding graphene's electrical properties on an atomic level
(Phys.org) —Graphene, a material that consists of a lattice of carbon atoms, one atom thick, is widely touted as being the most electrically conductive material ever studied. However, not all graphene is ...
