Brain-Like Computer Closer to Realization
New memory material may hold data for one billion years
(PhysOrg.com) -- Packing more digital images, music, and other data onto silicon chips in USB drives and smart phones is like squeezing more strawberries into the same size supermarket carton. The denser you ...
Scientists build 'single-atom transistor'
(PhysOrg.com) -- Researchers from Helsinki University of Technology (Finland), University of New South Wales (Australia), and University of Melbourne (Australia) have succeeded in building a working transistor, ...
Silicon oxide circuits break barrier: Nanocrystal conductors could lead to massive, robust 3-D storage
Rice University scientists have created the first two-terminal memory chips that use only silicon, one of the most common substances on the planet, in a way that should be easily adaptable to nanoelectronic ...
Engineers build first sub-10-nm carbon nanotube transistor
Scientists design solar cells that exceed the conventional light-trapping limit
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 ...
Ancient effect harnessed to produce electricity from waste heat
A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. ...
Researchers report first fully integrated artificial photosynthesis nanosystem
(Phys.org) —In the wake of the sobering news that atmospheric carbon dioxide is now at its highest level in at least three million years, an important advance in the race to develop carbon-neutral renewable ...
Laser the size of a virus particle operates at room temperature, defies the diffraction limit of light
A Northwestern University research team has found a way to manufacture single laser devices that are the size of a virus particle and that operate at room temperature. These plasmonic nanolasers could be readily integrated ...
A Billion Year Ultra-Dense Memory Chip (w/Video)
(PhysOrg.com) -- Berkeley Lab researchers have created a unique ultra-high density memory storage medium that can preserve digital data for a billion years.
Cat brain: A step toward the electronic equivalent
A cat can recognize a face faster and more efficiently than a supercomputer. That's one reason a feline brain is the model for a biologically-inspired computer project involving the University of Michigan.
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.
Researchers invent new method for graphene growth
(PhysOrg.com) -- A Cornell research team has invented a simple way to make graphene electrical devices by growing the graphene directly onto a silicon wafer.
