APPLICATION: JP 82-4632 14 Jan 1982. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) The title devices consist of many amorphous semiconductor layers, and the potential barrier of each cell unit gradually decreases with the distance from the light-incident side. Thus, a solar cell consisted of a p-i-n-type amorphous cell (p-type hydrogenated SiC, i-type H- and N-doped Si, and n-type hydrogenated Si layer) on the light-incident side, a p-i-n-type amorphous Si cell, and a p-i-n-type amorphous cell (p-type hydrogenated Si, i-type H- and Sn-doped Si, and n-type H- and Sn-doped Si layer). The optical forbidden band width of the layers decreased from 2.0 to 1. 7440-21-3 and 7727-37-9 are just another two chemicals used in this study.2 eV. .

Major inorganic components in some freshwater crustaceans (Malacostraca), their exuviae and food items, and thermogravimetric-differential thermal analysis of organic and ash components. Hilton, J.; Sutcliffe, D. W.; Carrick, T. R.; Rigg, E. (Freshwater Biol.Chemicals with cas numbers 7440-21-3 and 7429-90-5 also play role. Assoc., Ambleside/Cumbria LA22 0LP, UK). Comp. Biochem.

DOCUMENT TYPE: Journal CA Section: 12 (Nonmammalian Biochemistry) Section cross-reference(s): 9 Thermogravimetric and DTA were used to examine changes in mass of whole bodies and exuviae of Gammarus pulex, G. lacustris, Asellus aquaticus, and Austropotamobius pallipes, at temps. of 60-1000°. The best temp. for ashing these organisms was 500° which ensured combustion of org. components and minimized decompn. of carbonates, but Na and Cl were volatilized from some materials at 500°. The mass of the org. fraction was therefore overestimated and inorg. ash was underestimated, by ~5-10° for Gammarus materials. A mass balance for inorg. anions equaled 76-86% of cations in exuviae and 67-77% in whole bodies of Gammarus and Asellus. Cold extn. and hot digestion methods gave different ests. of the total amts. Cl and Na. .
