Transition metal interstitial compounds thin film preparation and superconducting properties, emphasizing high critical temperature, rock salt structure and NbN base
Slush H and N gels preparation and characteristics, including measurements of weight bearing capacity of gel as function of percent mass silica gelant
Procedure for preparing thin films for infrared spectrophotometric analysis involves pressing of a neat mixture of reactants between nonreactive thin polymer films with noninterfering absorption bands. Pressing is done under a pressure that gives desirable thickness. Following this process, the film sandwich is cut to accommodate the laboratory instrument.
