✦ Synopsis

We have developed quantitative equations for the resistive transition of a superconducting 2-dimensional granular array including the effects of intergranular charging energy. The equations are applied to thin BN-NbN cermet films. Results indicate that charging energy plays a significant role in the high sheet resistance, low T c samples.

Nonlinear current-voltage characteristics have been measured for ultrathin (16-400/~) YBa2Cu3Or\_6 films in high magnetic fields. A scaling analysis of these data reveals deviations from the universal vortex-glass critical scaling behavior observed for thick films. This is argued to be a dimensional

A model based on the two film approximation is proposed for the description of the kinetics of the hydrogen isotope exchange between CHCl3 and DzO. In this model, details of mass transfer in interfacial region between the two liquid phases are considered and the kinetics of the exchange reaction is
