DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Section cross-reference(s): 38 A solid polymeric electrolyte consists at least in part of a solid soln. of a closoborane of an alkali metal in a polymer or copolymer including heteroatoms capable of forming donor-acceptor type bonds with the cation of the closoborane. The invention also related to batteries in which the electrolyte is assocd. with an anode comprising an electrode material capable of supplying the same cation at its interface with the electrolyte and with a cathode forming a sink at a lower chem. potential for the nonionized species corresponding to the alkali cation. Thus, Li2B12H12 was solubilized in poly(ethylene oxide) [25322-68-3]. The solubilized amts. were such as to obtain O:Li ratio of 4-16. 72067-46-0 and 28854-71-9 which are cas registry numbers of substances are two of reagents here. A secondary battery was formed by assocg. the electrolyte film with a Li-Al anode and a cathode of composite agglomeration product of TiS2 and of the solid electrolyte. After a 1st loading, the open-circuit voltage was 2.3 V and the discharge current at 80° was >0.1 mA/cm2. .

Effect of pH and water-d2 on the temperature of thermal inactivation of chloroplasts

Effect of pH and water-d2 on the temperature of thermal inactivation of chloroplasts. Venediktov, P. S.; Krivosheeva, A. A. (USSR). Deposited Doc., VINITI 93-83, 12 pp. Avail. VINITI (Russian) 1983. DOCUMENT TYPE: Report CA Section: 11 (Plant Biochemistry) The temp. of Hill reaction inactivation was pH dependent and was max. 25322-68-3 and 14940-63-7 are cas registry numbers. These chemicals are also mentioned in this article. at pH 5.5. In a salt-free Hepes-Tris buffer the inactivation temp. was 45° at pH 5.5-7 and decreased to 30° at pH 7-9. In the presence of 100 mm NaCl or 5 mM MgCl2 in the Hepes-Tris buffer and in a citrate-phosphate buffer the inactivation temp. increased by 4-7° reaching at pH 5.5 48° for pea chloroplasts of the Pobiedidel and 51° for those of the Yubileinyi variety. High salt concns. decreased the chloroplast thermostability, esp. at low pH. Sucrose and polyethylene glycol (mo. wt. 15,000) increased the inactivation temp. at pH >5. In a medium contg. 95% D2O the max. inactivation temp. increased and the curve of pH dependency shifted by 0.5-1 pH units towards alk. pH values. EtOH (10%) decreased the inactivation temp. at acid pH values. Heat hardening of pea leaves increased the temp. of inactivation of leaf luminescence, but raised that of chloroplasts isolated from the hardened leaves. In fragments of membranes of thermophilic cyanobacteria the inactivation temp. was also highest at pH 5.5, but the max. inactivation temp. was 66°; sucrose increased the thermal stability of those membranes. .
