During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

First, the researchers used a short laser pulse about 200 nanometers in wavelength to excite ammonia molecules. This pump ...

Almost two decades ago, physicists detected a phenomenon known as the spin Hall effect 1, 2, in which an electric field separates the electrons in a material on the basis of their intrinsic angular ...

In a new study, an international group of researchers has found that chiral phonons can create orbital current without ...

How do different materials react to the impact of ions? This is a question that plays an important role in many areas of research -- for example in nuclear fusion research, when the walls of the ...

A new way of imaging frozen biological samples using electron microscopy is providing new glimpses into the nanoscopic world of cells. Images reveal bent in-vitro tubulin microtubules next to and in a ...
