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 ...

Proton transfer (PT) through and across aqueous interfaces is a fundamental process in chemistry and biology. Notwithstanding its importance, it is not generally realized that interfacial PT is quite ...

Charged particles in aqueous solutions are always surrounded by a shell of water molecules. However, much is still unknown about the nature of this so-called hydration shell. Using terahertz ...
