Experimental study of laser-induced processes on the surfaces of carbonaceous materials with simultaneous measuring of their temperatures

Results are presented from experiments on monitoring laser-induced processes (heating, melting, and ablation) on surfaces of carbonaceous materials (glassy carbon, pyrocarbon) using a laser display and according to the brightness temperature determined during these processes with a high-temperature pyrometer. The melting brightness temperature of glassy carbon (2720 ± 15 K) is determined using a continuouswave fiber laser. Some wave structures are revealed. No melting of pyrocarbon was observed over the range of powers and temperatures. The surfaces ablated after heating.

α-(3-Indolyl)-β-hydroxyethylamine and its derivatives

The reduction of oximes of 3-hydroxyacetylindole, 3-benzyloxyacetylindole, and 3-ethoxy-acetylindole (mixtures of syn and anti isomers) gave -(3-indolyl--hydroxyethylamine, -(3-indolyl)--benzyloxyethylamine, and -(3-indolyl)--ethoxyethylamine, the structures of which were confirmed by PMR and mass spectrometry.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 6, pp. 778–781, June, 1971.
