A few years ago, physicists were surprised to learn that stacking and subtly twisting two atomically thin layers of an ...

The simultaneous generation of an electron beam with high energy and high current density with a high-fill factor is challenging for a backward wave oscillator (BWO) and other linear-beam devices. To ...

Electric vehicles may be the biggest topic in alternative fuels, but they're not alone: Hydrogen-powered engines have existed for decades and are still around.

If hydrogen can be stored and carried safely at a high density, hydrogen-fuel cells offer effective solutions for vehicles. The stable chemisorption of atomic hydrogen on single layer graphene (SLG) ...

The spontaneous electron transfer capability of diaryl diselenides was demonstrated for the first time, leading to the sequestration of redox-prone radical cation intermediates via electron transfer ...

Gas-cell in-situ transmission electron microscopy (TEM) is utilized to reveal the failure mechanism of MEMS H2 gas sensor with PdAg@ZnO nanowires as the sensing material. The morphology evolution of ...
