- Created Chemicals, Gases and Reference Samples (assembly): "Oxide and carbonate powders are the precursors for YBa2Cu3O7 and the bismuth cuprates, with magnesium and boron for MgB2. Oxygen and argon supply the furnace and arc-melting atmospheres, liquid nitrogen cools samples, and known superconductors (a YBCO disk, a Bi-2223 bar, niobium, lead) check the measurement setups."
