When phones or computers are recycled, small amounts of important materials get discarded. Those minute amounts of cobalt, ...

I tried dropping sodium metal into sulfuric acid — and the reaction was way more intense (and dangerous) than I expected.

Sodium titanate nanotube/titanium metal composites were synthesized by hydrothermal treatment of titanium metals with various morphologies such as plate, wire, mesh, microsphere, and microtube at 160 ...
