Experimental data are used to determine the atomic volumes and radii of the elements of subgroups IV–VIIA in the structures of metallic phases at high pressures. Metallic radii of nonmetals are compared with values based on Pauling and Goldschmidt calculations.

Overhauser Effect in Nonmetals
Physical Review, 1955A survey is made of different ways in which nuclear spins can relax through their interaction with electronic spins. It is shown that the maximum amount of nuclear polarization which can be obtained by saturating the electronic resonance depends: (a) on the type of interaction between electronic and nuclear spins, namely dipole-dipole type, scalar ...

Proizvodnja anorganskih nemetalnih materijla ima veliko ekonomsko značenje i jedna je od najatraktivnijih gospodarskih grana razvijenih zemalja svijeta. Ta proizvodnja u Republici Hrvatskoj s obzirom na sirovinsku bazu nije zadovoljavajuća i daleko je ispoda realnih mogućnosti.

Abstract This chapter discusses the processes involved in the wetting, spreading, and chemical interaction of a braze on a nonmetal. The chapter reviews the key materials and process issues relating to the joining of nonmetals using active brazing. Emphasis is placed on the differences in brazing to metals by established methods.
