Rubidium atoms can exist in three states ... We’ve seen this done before, of course. Cesium is even more precise, but there are things still better than that.

Researchers at the University of California San Diego have been able to explain how adding small amounts of cesium or rubidium salt to perovskite-based solar cells can increase performance by ...

Rubidium could be the next key player in oxide ... Since Rb + is one of the largest cations (second only to the cesium ion), crystalline Rb-containing oxides are expected to have a larger lattice ...

While a cesium clock may be off one second in 100 ... If you want to build your own clock, you might start with rubidium at a less accurate 6.8 GHz. If you want to know more about how atomic ...
