media object: Cadmium

In this new Everything Matters segment, get to know the colorful element cadmium. Once used in rechargeable batteries, TV picture tubes, and artists' pigments (its use has been curtailed due to its toxic nature, though you can still find Cadmium Red and Yellow paint if you look), its light once served as the standard for measuring certain lengths. Today, you'll find it in photocells, quantum dots for LCD televisions, control rods in nuclear reactors, and solar cells.

In the spirit of amplifying the Black Lives Matter movement and to avoid any appearance of having appropriated that title, our series of talks formerly called Everything Matters: Tales from the Periodic Table will now be called, simply, Tales from the Periodic Table. Please excuse the former title on videos made in the past.
