0-D: Zero-dimensional quantum dots identified by researchers
(Phys.org) —In physics, there's small, and then there's nullity – as in zero-dimensional.
New 'pomegranate-inspired' design solves problems for lithium-ion batteries
with silicon nanoparticles clustered like seeds in a tough carbon rind – overcomes several remaining obstacles to using silicon for a new generation of lithium-ion batteries, say its inventors at Stanford ...
Beyond the Moore's Law: Nanocomputing using nanowire tiles
An interdisciplinary team of scientists and engineers from The MITRE Corporation and Harvard University have taken key steps toward ultra-small electronic computer systems that push beyond the imminent end ...
Bacterial nanowires: Not what we thought they were
For the past 10 years, scientists have been fascinated by a type of "electric bacteria" that shoots out long tendrils like electric wires, using them to power themselves and transfer electricity to a variety ...
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 ...
Scientists investigate how ice melts below freezing due to nanowire's pressure
New solar-cell design based on dots and wires
Using exotic particles called quantum dots as the basis for a photovoltaic cell is not a new idea, but attempts to make such devices have not yet achieved sufficiently high efficiency in converting sunlight ...
Scientists investigate atomic-scale mechanisms of nanowire growth process
Researchers make first all-optical nanowire switch
(Phys.org)—Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1's and 0's were represented by bursts of light, instead of electricity.
Tiny lasers light up future electronics
(Phys.org) —Faster, smaller electronics are one step closer with researchers from The Australian National University successfully making the first room temperature lasers from gallium arsenide nanowires.
Researchers improve performance of III-V nanowire solar cells on graphene
(Phys.org) —Imagine a field of small wires—standing at attention like a tiny field of wheat—gathering the Sun's rays as the first step in solar energy conversion.
New 'FeTRAM' is promising computer memory technology
(PhysOrg.com) -- Researchers are developing a new type of computer memory that could be faster than the existing commercial memory and use far less power than flash memory devices.
Triple point: Physicists pinpoint key property of material that both conducts and insulates
It is well known to scientists that the three common phases of water – ice, liquid and vapor – can exist stably together only at a particular temperature and pressure, called the triple point.
Extra-short nanowires best for brain
If in the future electrodes are inserted into the human brain - either for research purposes or to treat diseases - it may be appropriate to give them a 'coat' of nanowires that could make them less irritating for the brain ...
