The effect of time and temperature on the properties and structure of a willemite glass‐ceramic were measured. ‐0 polymorphs of willemite were found to exist in most of the glass‐ceramics. Those properties of the glass‐ceramic which depend primarily on the composition of the glassy phase (helium permeation and diffusi…

The stepwise protonation of three polymeric amines, containing a different shielding group between the amine moieties of the repeating units, has been studied from a thermodynamic standpoint. This was done for comparison purposes with structurally related poly(amido amines) whose monomeric units had been previously fo…

Ferrous/ferric equilibria were determined in alkali‐alkaline‐earth borosilicate glass as a function of temperature, oxygen partial pressure, and glass composition. Expected linear relations are found between log(Fe 2+ /Fe 3+ ) and log( p O 2 ) or 1/ T . The slopes of the correlation with 10g( p O 2 ) are near the expe…

We present results of calculations of the reflectivity of diffraction gratings of sawtooth profile, and of electric fields near such gratings. We employ a method based on the use of the extinction theorem, and the grating amplitude is not assumed small. This approach also allows one to calculate the electric fields wi…

The hydride Mg2NiH4 exhibits a phase transition from a low temperature to a high temperature phase at about 508 K. The dynamics of the hydrogen in the high temperature phase have been studied by cold neutron scattering experiments. According to these, the hydrogen atoms showed a high mobility, but the motion was mainl…

This work concerns three questions: How can one decide whether a particular liquid metal will wet a given oxide substrate? What does analysis of experimental data tell one about the nature of the metal-substrate interactions? Is there correlation with strong metal-support intereactions in catalysis? Comparison of the…
