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.
A research team led by Professor Hoi-Jun Yoo of the Department of Electrical Engineering has developed a semiconductor chip, CNNP (CNN Processor), that runs AI algorithms with ultra-low power, and K-Eye, a face recognition system using CNNP.
Using femtosecond visible and terahertz (THz) pulses as external perturbations, scientists at Tokyo Institute of Technology and Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) have investigated the second harmonic generation effect in photoexcited BiCoO3. Driven by the THz pulse, this research highlights the importance of orbital excitation in the Co3+ ion and provides clues for improving the performance of nonlinear optical phenomena in nonlinear crystals on the femtosecond time scale.
Osaka University researchers create new material based on gold and black phosphorus to produce clean hydrogen fuel using the full spectrum of sunlight.
The 12 articles in the special issue of Advanced Electronic Materials investigate materials and devices that are being researched for their applications in micro-electronics, opto-electronics, thermo-electricity generation, photovoltaics and quantum technologies.
Researchers at the University of Illinois at Urbana-Champaign have developed a new nanoscale memory cell that holds tremendous promise for successful integration with superconducting processors. The new technology, created by Professor of Physics Alexey Bezryadin and graduate student Andrew Murphy, in collaboration with Dmitri Averin, a professor of theoretical physics at State University of New York at Stony Brook, provides stable memory at a smaller size than other proposed memory devices.
