The quantum dots in TVs controversy goes to court, with a Chinese vendor saying it uses cadmium in sets
It said the quantum dot ones in TCL sets contain at lest four micrograms of cadmium per kilogram. Cadmium-selenide (CdSe) is a compound used to make quantum dots. The presence of CdSe in TCL TVs ...

How Do Batteries Work?
Anode – Typically made of reactive materials like lithium or zinc, the anode undergoes oxidation, releasing electrons. Cathode – A material capable of accepting electrons, the cathode undergoes ...
