Mechanisms of Diffusion-Reduction Interaction of Microcrystalline Cellulose and Silver Ions

Mechanisms of Diffusion-Reduction Interaction of Microcrystalline Cellulose and Silver Ions. Kotel'nikova, N. E.; Demidov, V. N.; Wegener, G.; Windeisen, E. ( Institute of Macromolecular Compounds, Russian Academy of Sciences, St.Several reagents with their cas registry numbers 7761-88-8 and 7782-87-8 are used here. Petersburg, Russia). Russian Journal of General Chemistry (Translation of Zhurnal Obshchei Khimii), 73(3), 427-433 (English) 2003 MAIK Nauka/Interperiodica Publishing. CODEN: RJGCEK. ISSN: 1070-3632. DOCUMENT TYPE: Journal CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 78 The prepn. of microcryst. cellulose samples contg. intercalated silver(0) particles includes two main stages: diffusion of silver ions from aq. AgNO3 into the microcryst. cellulose matrix, followed by redn. of the silver ions bound to cellulose macromols. to Ag(0) and growth of Ag(0) particles inside the cellulose matrix and on its surface. Mechanisms of interaction of silver ions with cellulose as reducer and with other reducers and ligands are considered. .

Potassium phosphinate in zinc electroplating of steel sheet

Potassium phosphinate in zinc electroplating of steel sheet. Koga, Takeshi; Suzukawa, Hiroyoshi (Kawasaki Steel Corp., Japan). Jpn. Kokai Tokkyo Koho JP 61217595 A2 27 Sep 1986 Showa, 3 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C25D007-06.There are some reagents with their cas registry numbers 12597-69-2 and 7782-87-8 are used in this study. ICS: C23C022-07. ICA: C25D003-22. APPLICATION: JP 85-55969 22 Mar 1985. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) Section cross-reference(s): 72 The steel sheet, e.g. for automotive panels, is electroplated with Zn in a bath contg. KH2PO2 for the improvement of conversion coating for secondary adhesion of a paint. An electroplating bath (50°) contg. ZnSO4.7H2O 400 and KH2PO2 0.5 g/L, for example, shows the claimed effect. .
