How glass learns to illuminate itself and create heat

Among other things, this can be used to produce electrically conductive and self-heating glass microreactors for the chemical and pharmaceutical industries

31-Mar-2022

Glass objects which glow in the dark, glass containers that heat up and cool down, or glass control knobs and switches that eliminate viruses and bacteria by themselves – all this seems to completely contradict our everyday experience of what glass can do. And yet, it is now within reach. To ...
