Anion exchange membrane fuel cells (AEMFCs) have gained attention in the process of fuel cell development because they operate in alkaline environments, the redox reaction rate at the electrodes is ...

In a major physics breakthrough, scientists in New Zealand have developed a technique to consistently isolate and capture a fast-moving neutral atom -- and have also seen and photographed this atom ...

Chemists have found that the all-cis isomer of hexafluorocyclohexane, a molecule that made headlines last year for being the most polar aliphatic compound known, is capable of binding both cations and ...

When scientists at Caltech revealed that they had assembled the world’s largest neutral-atom quantum computer, the announcement sent waves across both academia and industry. By trapping and ...

All chemists are familiar with the litmus test. Like other acid-base indicators, litmus changes color when the pH of a solution changes. The indicator is an example of a "naked-eye" colorimetric ion ...
