La conversion a basse temperature de l'hydrogene sur l'or diamagnetique fournit, quoique dans une mesure moindre qu'avec l'aluminium paramagnetique, des indications sur les valences libres superficielles postulees dans des calculs sur les chaleurs de

Thin films of gold were deposited by evaporation onto glass surfaces generated by slow fracture in a vacuum. Such films characteristically show an agglomerated or coalesced structure. Deliberate contamination of the substrate and growing films with O

The mechanism of parahydrogen conversion was studied on Gd2O3 and Y2O3 powders and on Gd and Y evaporated metal films at low and high temperatures (77° to 90°K and 298° to 418°K). Absolute rates of conversion are compared to theoretical values fo

The surface states of silica in the forms quartz, cristobalite, and silicic acid were studied by investigating the kinetics of para-ortho hydrogen conversion and of hydrogen-deuterium equilibration from 93° to 773°K. The products of conversion were

The adsorption of calcium lignosulfonate and salicylic acid was studied on the hydration products of the four principal components of portland cement. To investigate the adsorption as a function of development of hydration product, the determinations

In an attempt to verify theories on the effect of admixtures on portland cement, the adsorption isotherms for calcium lignosulfonate and salicylic acid on cement have been determined. The adsorption isotherms for these compounds on 3CaO·SiO2, 2CaO·

Contact angles, surface free energies, and work of adhesion were determined by a sessile drop technique for the wetting of MgO, Al2O3, and SiO2 by In, Ga, and Sn at 10-10 torr. The surface free energies of In, Ga, and Sn were 540, 632, and 573 ergs/c
