Grain-boundary migration in KCl bicrystals
Boundary migration in melt-grown bicrystals of KCl containing pure twist boundaries was investigated. The experiments involve the use of bicrystal specimens in the shape of right-triangular prisms with the boundary parallel to one side.

Growth of phase-pure, crack-free single crystals and large-grained polycrystals of molybdenum disilicide
High purity molybdenum disilicide crystals are prepared by zone melting sintered compacts. This method yields single crystals or polycrystals free from macrocracks which allow better measurement and evaluation of mechanical properties.

Reflection spectra of lunar dust grains with amorphous coatings.
The suggestion of Bibring et al. (1971) that the low albedos and reddish spectra observed in some lunar fines are caused by a low density amorphous substance which coats the fines is disputed. It is shown that these coatings have only a marginal effect on lunar reflectivity.
