EFFECT OF SURFACE ROUGHNESS ON EMITTANCE OF NONMETALS
Journal of the Optical Society of America, 1965It has been observed experimentally, both at NBS and elsewhere, that the emittance of polished metals can be markedly increased by roughening the surface, by as much as a factor of 2 or 3. For nonmetals and particularly white ceramic materials, on the other hand, the emittance appears to be essentially independent of surface roughness, at least for ...

The mechanical properties of polymers differ fundamentally in many respects from those of metals and much of this difference can be ascribed to the characteristic structures of these two classes of material. Most polymers consist of long molecular chains which are built up from a large number of single molecular units called mers.

Carbene Complexes of Nonmetals
European Journal of Organic Chemistry, 2005AbstractElectrophilic carbenes accept a variety of n‐ and π‐donors. The products range from persistent ylides to matrix‐isolated xenon complexes. Ylides can be viewed as carbene complexes if they regenerate carbenes thermally or undergo concerted methylene transfer reactions.

Electronic Polarons in Nonmetals
Physical Review B, 1972We use the techniques of perturbation theory and the electronic polaron to classify and obtain explicit formulas for electronic correlation in nonmetals. We consider explicitly the case in which the highest valence band is $p$ type and the lowest conduction band is $s$ type or vice versa, a situation which holds for all rare-gas solids, alkali halides,

Perfluorovinyl derivatives of nonmetals
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19601. As a result of the reaction between perfluorovinylmagnesium iodide and PCl3, AsCl3, and SbCl3, the corresponding tris-(trifluorovinyl)-phosphine, tris-(trifluorovinyl)-arsine, and tris-(trifluorovinyl)-stibine were obtained. 2. Amides of the type ClP(NR2)2 reacted smoothly with R'MgX (where R' is alkyl or perfluoroalkenyl) to form ...

Russian Chemical Bulletin, 1994
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.
