The title compound, Ca[Sn(H2PO2)6], was formed after a few days when tin(II) fluoride was allowed to react with phosphinic acid at ambient conditions. The structure consists of chains of Ca(2+) and Sn(4+) cations in octa-hedral sites with -3 symmetry bridged by bidentate hypophosphite anions. The chains are hexa-gonally close packed along [001]. The discovery of the compound and the successful ...

We report synthesis of cetyltrimethyl ammonium bromide (CTAB) stabilized Zn1+xSnO3+x (0 ≤ x ≤1) nano-crystallites by facile cost-effective wet chemistry route. The X-ray diffraction patterns of as-synthesized powders at the Zn/Sn ratio of 1 exhibited formation of ZnSn(OH)6. Increasing the Zn/Sn ratio further resulted in the precipitation of an additional phase corresponding to Zn(OH)2. The deco...

In recent years, the particular interest of researchers is focused on such enzymes as α-L-rhamnosidase and α-galactosidase. These are considered useful for various applications. α-L-rhamnosidases may be applied debittering citrus fruit juices, due to less bitter taste derhamnosylated flavonones, rhamnose production, determination anomeric configuration in polysaccharides, glycosides glycolipids...

Abstract Y 2 Ti 2− x Sn O 7 ( = 0–2) pyrochlore sodium aluminoborosilicate glass–ceramics (GCs) are produced by calcining the pelletized Y–Ti–Sn oxide mixture and glass precursor at 1200 or 1300°C for 4 h. The metal is prepared a soft chemistry route. X‐ray diffraction, Raman spectroscopy, electron microscopy employed to investigate formation of GCs local crystal structures. Near phase pure Ti‐...

Although alloy tin plating has been known and used for many years, this paper will describe the use of a new non-cyanide tin/zinc alloy as a possible replacement coating for cadmium and the use of a tin/nickel alloy as a possible substitute for barrel decorative chromium plating. A review on the corrosion properties of tin, zinc and cadmium compared to tin/zinc alloys and review of the properti...
