A counterintuitive case in which like charges attract

When it comes to electric charge, there is one overriding theme: opposites attract, and like charges repel. But in a new study, physicists have made the surprising discovery that two spherical like-charged metal nanoparticles ...

Upgrading the vanadium redox battery

Though considered a promising large-scale energy storage device, the vanadium redox battery's use has been limited by its inability to work well in a wide range of temperatures and its high cost. But new research indicates ...

Good vibrations lead to molecular revelation

(PhysOrg.com) -- A little luck and the wisdom to recognize what they were seeing helped Rice University researchers solve a molecular conundrum in a way that could be a boon to chemists.

Putting the pedal to the metal: Lithium metal improves fuel cells

(PhysOrg.com) -- Water splitting is a clean way to generate hydrogen, which is seen by many as the fuel of the future. Scientists from the Energy Technology Research Institute, AIST in Tsukuba, Japan now report in ChemSusChem ...

Recipe for safer batteries—just add diamonds

While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due ...

Giant charge reversal observed for the first time

Charged surfaces submerged in an electrolyte solution can sometimes become oppositely charged. This nonintuitive phenomenon, known as charge inversion, happens when excess counter ions adsorb, or adhere, to the surface. It ...

Chemists create vitamin-driven battery

A team of University of Toronto chemists has created a battery that stores energy in a biologically derived unit, paving the way for cheaper consumer electronics that are easier on the environment.
