Quantum effects detected in hydrogen and noble gas collisions

A Freie Universität Berlin research team headed by quantum physicist Professor Christiane Koch has demonstrated how hydrogen molecules behave when they collide with noble gas atoms such as helium or neon. In an article published ...

Superconductivity with Tc as high as 32K found in borides

Superconductors with high transition temperature (high-Tc SCs) are long-sought targets in the condensed matter physics and materials communities because of significant scientific and application values. Since the discovery ...

Unusual interactions between polymers explain hydrogel formation

Many people use hydrogels without knowing it. As superabsorbents in nappies, for example, hydrogels absorb a lot of liquid. In the process, the initially dry material becomes jelly-like, but it does not wet. Some people place ...

Defying gravity with the Brazil nut effect

Physicists from the University of Utrecht and the Faculty of Physics at the University of Warsaw have observed—for the first time experimentally—the Brazil nut effect in a mixture of charged colloidal particles.

Visualizing differences in nuclear structure

Helium usually has two protons and two neutrons strongly bound to each other, often forming a substructure within the nucleus. A nucleus composed of several such substructures is called a cluster structure. In the standard ...

Simplified calculations reproduce complex plasma flows

Accurate and fast calculation of heat flow (heat transport) due to fluctuations and turbulence in plasmas is an important issue in elucidating the physical mechanisms of fusion reactors and in predicting and controlling their ...
