Abstract: NOVEL COMPOSITIONS OF MATTER FORMED OF AMMONIA, HYDRAZINE, AND ORGANIC NITROGEN COMPOUND INTERCALATES AND HEAVY METAL LAYERED CHALCOGENIDES, WHEREIN THE CHALCOGEN IS SELECTED FROM SULFUR, SELENIUM AND/OR TELLURIUM. THE NOVEL INTERCALATED COMPOUNDS DISPLAY ADVANTAGEOUS CARACTERISTICS WHEN UTILIZED AS SOLID LUBRICANTS, AND AS DIFFRACTION GRATING CRYSTALS. CERTAIN OF THE INTERCALATED TRANSITION METAL CHALCOGENIDES ALSO EXHIBIT UNIQUE SUPERCONDUCTIVITY CHARACTERISTICS.

Abstract: COMPOUNDS AND METHOD FOR ASSAYING ENZYMES BY ADDING TO A MEDIUM CONTAINING AN ENZYME A STABLE FREE RADICAL COMPOUND HAVING A STABLE FREE RADICAL FUNCTIONALITY, BONDED DIRECTLY OR INDIRECTLY TO AN ENZYME LABILE FUNCTONALITY, WHICH WHEN SUBJECTED TO AN EMZYNE CATALYZED REACTION CHANGES THE ENVIRONMENT OF THE FREE RADICAL FUNCTIONALITY. BY FOLLOWING THE CHANGE IN THE ELECTRON SPIN RESONANCE (ESR) SPECTRUM AS AFFECTED BY THE CHANGE IN ENVIRONMENT, THE TYPE OF ENZYME AND ACTIVITY OF ENZYME MAY BE DETERMINED.
