The world of science is always in a state of flux, evolving and growing with each new discovery. Recently, the race to create the blackest material has seen an exciting development. A newly created ...

Normally, an object in thermal equilibrium with its environment emits and absorbs thermal radiation at the same rate (left). But researchers have developed a multilayer material (right) that, when ...

Renewable energy of the future is concentrated solar power because it can be easily used to store thermal energy. Despite the fact that, historically, it is more expensive and complex than ...

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...

Bandgap materials are solids – primarily semiconductors and insulators – that possess an energy gap between their valence band and conduction band. This gap, measured in electron volts (eV), dictates ...

New results published in the journal Physical Review Letters detail how a specially designed metamaterial was able to tip the normally equal balance between thermal absorption and emission, enabling ...
