Abstract: Stable, bulk electrical superconductors are prepared by heating mixed metal oxides in the presence of oxygen in a closed vessel in a preheated oven for 1-5 hours at 850-900 DEG C. The final oxides are in the molar ratio Tl0.6-1.1Ca2-3Ba0.75-1.25Cu2-3O(5+ delta )-(9+ delta ), where delta is less than one.

Abstract: Hydrogen is generated from water containing acid by passing electric current through it, using as the cathode a semiconductor exposed to light and having a transition metal metallocenophane compound attached to the surface of the cathode by means of a polymer.
