Limited wavelengths: the Casimir effect arises because virtual photons at certain wavelengths cannot emerge in a gap between two plates (Courtesy: iStock/4X-image) Physicists in the US have worked out ...

Metal oxides are abundant in nature and central to technologies such as photocatalysis and photovoltaics. Yet, many suffer from poor electrical conduction, caused by strong repulsion between electrons ...
