Poly(vinyl chloride) membrane electrode on a graphite substrate for the potentiometric titration of tetramethylammonium bromide with sodium tetraphenylborate
Influence of surfactants on contact angles of ceramic brick-aqueous solution-air and sand lime brick-aqueous solution-air
A radiotracer determination of the sorption of sodium ions by microporous silica films
Influence of quartz surfaces on the reaction C3A + CaSO4.2H2O + water
Quartz surfaces counteract the retarding action of SO42- on the hydration of C3A, by presenting additional sites for ettringite crystallization. Strong retardation requires the presence of ettringite near the C3A, influencing the local concentrations there

An improved apparatus for the measurement of zeta potentials of rod-shaped materials
The method is based on measurement of the electroosmosis of the system formed by a rod placed in a cyclindrical hole in a piece of another material (P) leaving a narrow space between rod and hole wall. The zeta potential (z2) of the hole wall was described previously (S. and Stein, 1977); the zeta potential of the rod can be calcd. from z2 and the electroosmosis data. Measurements can be made in the same app. (at the same time) as radiotracer studies of ion adsorption on the rod
