Light opens and closes windows in membranes

Scientists have developed novel membranes, whose selectivity can be switched dynamically with the help of light. For this purpose, azobenzene molecules were integrated into membranes made of metal-organic frameworks (MOFs).

Stability challenge in perovskite solar cell technology

New research results suggest that the degradation of MAPbI3 perovskites may not be a fixable issue.

Fluorescence microscopy: It cannot get any sharper

Researchers achieve ultimate resolution limit in fluorescence microscopy.

The hidden inferno inside your laser pointer

Physicists have discovered that concepts such as 'hot' or 'cold' apply to any system, even those far from equilibrium. The findings could possibly inform the design of future microelectronic devices.
