Tracer exchange reveals ions can speed up or slow down inside battery solids

Understanding how ions diffuse in solid materials is essential for technologies including batteries, electronics and chemical catalysts, but it has been hard for a simple reason: the materials are solids.

Why nanoscale droplets don't coalesce and microscale droplets do

Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...
