A new type of radiofrequency trap can capture particles with extremely different requirements and could theoretically hold ...

Ion channels are pores in the membrane of cells or cell organelles. They allow positively or negatively charged particles, so-called ions, to be transported across the membrane. Biochemists at ...

The first digital “quantum simulator” based on trapped ions has been built by physicists in Austria. The system, developed by Ben Lanyon and colleagues at the University of Innsbruck, comprises a ...

A tabletop-sized ion trap in Mainz, Germany, has confined both electrons and calcium ions using two overlapping ...

Renewable energy and electric cars are driving demand for batteries with denser energy storage than standard lithium-ion batteries. Ions that can carry more than one charge, such as calcium and ...

Researchers in Germany have moved closer to synthesizing antihydrogen after successfully confining heavy calcium ...

Calcium is a very special nutrient. In the cells of most living beings calcium ions function as so-called second messengers to transmit important signals. The same applies equally to animal, plant and ...
