Sodium-ion batteries: How doping works

Sodium-ion batteries still have a number of weaknesses that could be remedied by optimizing the battery materials. One possibility is to dope the cathode material with foreign elements. A team from HZB and Humboldt-Universität ...


Popping a champagne cork reveals propulsive dynamics

Researchers have resolved the complex gas dynamics that occur upon opening a champagne bottle (or, more generally, a bottle containing a pressurized liquid and gas) and these dynamics' interaction with the bottle's cork stopper. ...
