Phys.org / Organic materials conduct ions in solids as easily as in liquids thanks to flexible sidechains

Normally, when liquids solidify, their molecules become locked in place, making it much harder for ions to move and leading to a steep decrease in ionic conductivity. Now, scientists have synthesized a new class of materials, ...

Phys.org / Active thermal metasurfaces amplify heat signatures by a factor of nine

Light undergoes a unique phenomenon called superscattering, an optical illusion where a very small object scatters far more light than expected. This happens when multiple scattering modes overlap and interact, allowing tiny ...
