Toxicological investigations on silicon carbide. 2. In vitro cell tests and long term injection tests.

Silicon carbide (SiC) dust and other dusts for comparison were injected intratracheally at a high dose (50 mg) into rats and the response of the lungs and the lymph nodes was studied after an appropriate experimental period. The indices studied were: histological changes in the lung and lymph nodes, organ weights, the formation of collagenous fibres, and the appearance of quartz typical areas. ...

Toxicological investigations on dimethylformamide.

The boiling point is 1530 C., and it is miscible with water and some organic solvents. On boiling with water or alkali it hydrolyzes to formic acid and dimethylamine. It is more stable than formamide and can be distilled. For the present work freshly distilled dimethylformamide was used and all aqueous solutions were freshly prepared. Dimethylformamide in the atmosphere may be trapped by passin...

Molecular dynamics studies of Radiation Effects in Silicon Carbide

We discuss results of molecular dynamics computer simulation studies of 3 keV and 5 keV displacement cascades in p-Sic, and compare them to results of 5 keV cascades in pure silicon. The Sic simulations are performed with the Tersoff potential. For silicon we use the Stillinger-Weber potential. Simulations were carried out for Si recoils in 3 dimensional cubic computational cells with periodic ...
