MIT researchers have identified the proper temperature and chemical mixture to selectively separate pure copper and other metallic trace elements from sulfur-based minerals using molten electrolysis.

Photochromic materials can reversibly change their color and optical properties when irradiated with ultraviolet or visible light. However, they are made from organic compounds that are expensive to ...

Copper sulfide nanostructures encompass a family of p-type semiconductors with stoichiometries ranging from CuS (covellite) to Cu₂S (chalcocite), exhibiting band gaps between approximately 1.0 and 2.5 ...
