Anodes for sealed nickel-cadmium secondary batteries: Anodes for sealed nickel-cadmium secondary batteries. (Shin Kobe Electric Machinery Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58117641 A2 13 Jul 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: H01M004-28. APPLICATION: JP 81-215119 29 Dec 1981. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) An anode ingredient is filled into a porous sintered Ni sheet and the composite is immersed into a viscous and hydrophilic polymer solvent and then electrochem. oxidized in an acidic or neutral soln. to prep. an anode. The anode adsorbs O formed during the battery use. Thus, an anode composite was immersed into ethylene glycol at 30° and then electrochem. oxidized in 0.In this experiment, several chemicals are used like 7440-43-9 1N H2SO2 for 2 min at 1 A/dm2. The electrode extended battery life. .

Induction and characterization of metallothionein in the liver and kidney of Japanese quail: Induction and characterization of metallothionein in the liver and kidney of Japanese quail. Yamamura, Mitsuru; Suzuki, Kazuo T. (Natl. Inst. Environ. Stud., Tsukuba 305, Japan).Chemical with cas number 7440-43-9 also plays role. Comp. Biochem. Physiol., B: Comp. Biochem., 77B(1), 101-6 (English) 1984. CODEN: CBPBB8. ISSN: 0305-0491. DOCUMENT TYPE: Journal CA Section: 12 (Nonmammalian Biochemistry) The low-mol.-wt. Cd-binding protein induced in the liver and kidney of Japanese quail by Cd2+ injection was a mixt. of 2 isoproteins. The injection of Cd2+ induced the 2 isoproteins at a relative ratio of 6:1 regardless of single or multiple injections. The isoproteins had an apparent mol. wt. of ~12,000 daltons and were abundant in half-cystine (36.8 and 38.3 mol%) without arom. amino acids, indicating that the 2 isoproteins are metallothioneins (MT). The major isoform, MT-II, contained 1 residue of histidine and the amino acid compn. was similar to that of chicken metallothionein; that of the minor isoform, MT-I, was slightly different from that of chicken. .
