The hype around hydrogen fuel cells has died down, but scientists have continued to pursue new technologies that could enable such devices to gain a firmer foothold. Now one team has developed an electrocatalyst to replace the currently dominant, but expensive, one of choice -- platinum -- that could help boost the fledgling fuel-cell industry. Their report appears in the journal ACS Nano.
One of the greatest challenges facing artificial intelligence development is understanding the human brain and figuring out how to mimic it. Now, one group reports in ACS Nano that they have developed an artificial synapse capable of simulating a fundamental function of our nervous system -- the release of inhibitory and stimulatory signals from the same 'pre-synaptic' terminal.
Researchers from TU Graz and the University of Graz present the new method of 3-D-plasmon tomography in Nature Communications.
Researchers created an atomically thin material at Berkeley Lab and used X-rays to measure its exotic and durable properties that make it a promising candidate for a budding branch of electronics known as 'spintronics.'
New research by Berkeley Lab scientists could help usher in a new generation of high-definition displays, optoelectronic devices, photodetectors, and more. They have shown that a class of 'soft' semiconductors can be used to emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers. The work could challenge quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light.
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals -- a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
New research into the largely unstudied area of heterostructural alloys could lead to greater materials control and in turn better semiconductors, advances in nanotechnology for pharmaceuticals and improved metallic glasses for industrial applications.
Argonne researchers have identified a nickel oxide compound as an unconventional but promising candidate material for high-temperature superconductivity. The project combined crystal growth, X-ray spectroscopy and computational theory.
Frequent measurement of a quantum system's state can either speed or delay its collapse, effects called the quantum Zeno and quantum anti-Zeno effect. But so too can 'quasimeasurements' that only poke the system and garner no information about its state.
Javier Vela, scientist at the US Department of Energy's Ames Laboratory, believes improvements in computer processors, TV displays and solar cells will come from scientific advancements in the synthesis of low-dimensional nanomaterials.
