A new theoretical model enlightens the structure and the electrical properties of pure and doped ice. A fascinating substance with unique properties, ice has intrigued humans since time immemorial. Unlike most other materials, ice at very low temperature is not as ordered as it could be. A collaboration between the […]

Ultra-thin gold lamellae drastically amplify the incoming terahertz pulses (red) in the underlying graphene layer, enabling efficient frequency multiplication. Credit: HZDR/Werkstatt X On the electromagnetic spectrum, terahertz light is located between infrared radiation and microwaves. It holds enormous potential for tomorrow’s technologies: Among other things, it might succeed 5G by […]

Scientists at The University of Tokyo use computer simulations to model the effects of elemental composition on the glass-forming ability of metallic mixtures, which may lead to tough, electroconductive glasses.

Diamond could conduct electricity like metals when it is deformed to strains at the nanoscale, according to predictions from a study by an international team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) and the Massachusetts Institute of Technology (MIT), USA. Using computer simulations, the team, which also […]

Substituting deuterium for hydrogen makes methylammonium heavier and slows its swaying so it can interact with vibrations that remove heat, keeping charge carriers hot longer.

ANIMATION Researchers at Linköping University have developed a molecule that absorbs energy from sunlight and stores it in chemical bonds. A possible long-term use of the molecule is to capture solar energy efficiently and store it for later consumption. The Earth receives many times more energy from the sun than […]

Scientists have directly seen the first step in a light-driven chemical reaction for the first time. They used an X-ray free-electron laser at SLAC to capture nearly instantaneous changes in the distribution of electrons when light hit a ring-shaped molecule called CHD. Within 30 femtoseconds, or millionths of a billionth […]

A new “refrigerator” super-cools molecules to nanokelvin temperatures. The technique may enable more complex, molecule-based quantum computing. Credit: José-Luis Olivares, MIT Technique may enable molecule-based quantum computing. For years, scientists have looked for ways to cool molecules down to ultracold temperatures, at which point the molecules should slow to a […]
