Electric space propulsion systems use energized atoms to generate thrust. The high-speed beams of ions bump against the graphite surfaces of the thruster, eroding them a little more with each hit, and are the systems' primary ...
Over the past century, more than 16 million ocean temperature profiles had been collected by various instruments. However, each instrumentation provides data of different accuracy, different quality, and different completion ...
Quantum sensors can be used to reveal a surprising new mechanism for converting light into electricity in Weyl semimetals, Boston College (BC) Assistant Professor of Â鶹ÒùÔºics Brian Zhou and colleagues report in the journal ...
Researchers at Hokkaido University in Japan have combined natural squid tissues with synthetic polymers to develop a strong and versatile hydrogel that mimics many of the unique properties of biological tissues. Hydrogels ...
Aerosols are tiny particles that can have a significant impact on Earth's climate and human health.
Plasma is matter that is so hot that the electrons are separated from atoms. The electrons float freely and the atoms become ions. This creates an ionized gas—plasma—that makes up nearly all of the visible universe. Recent ...
Bosons, one of the two fundamental classes of particles, have been the focus of countless physics studies. When bosonic particles are transitioning into an already occupied final quantum state, the rate of this transition ...
The optical, electrical and mechanical properties of some materials change depending on the direction or orientation of the material. Depending on how wood is cut, for example, the orientation of the wood grain can result ...
While conducting an otherwise straightforward investigation into the assembly mechanism of calcium-phosphate clusters, researchers at UC Santa Barbara and New York University (NYU) made a surprising discovery: Phosphate ions ...
A paper published on Dec. 21 in Energy Material Advances reviews improvement strategies for the electrocatalytic activities of transition metal nitrides (TMNs) on hydrogen evolution reaction.
