The temperature dependence of the area-specific conductance of egg-lecithin/cholesterol bilayers formed with n-hexadecane in 1 mM KCI has been studied. From Arrhenius plots the activation energy for conduction was measured as 35 -+ 2 kJ/mol. Comparison of this value with those predicted by various m

The electrical conductivity of coal, at either 1 kHz or d.c., was measured at 24Β°C on samples recovered from pyrolysis experiments aimed at modelling conditions during in situ gasification of coal. From an initial value of low3 S/m (when the coal is saturated with formation water), the conductivity
## Abstract Anomalies in the temperature dependence of the conductivity of BF~4~^β^ doped polypyrrole were observed in cyclic measurements at temperatures between 250 K and 310 K. The anomalies were accompanied by endothermic effects in differential scanning calorimetry and are interpreted as being
