Preparation of multiple-cation alpha-SiAlON ceramics containing lanthanum
(Amer Ceramic Soc, 1999)
Until recently, it was accepted that Ce3+ cations, with an ionic radius (r) of 1.03 Angstrom, were too large to form an alpha-SiAlON structure. However, more-recent studies have shown that cerium cations can be incorporated ...
Latex supported manganese(III) porphyrin catalysts for oxidations of alkenes by hydrogen peroxide and tert-butyl hydroperoxide in the aqueous medium
(Scientific Technical Research Council Turkey-Tubitak, 1996)
Cationic polymer latexes were prepared by emulsion copolymerization of vinylbenzyl chloride and divinylbenzene followed by quaternization with trimethylamine and used as catalyst supports for 5,10,15,20-tetrakis(2, ...
Preparation of multiple-cation ?-SiAlON ceramics containing lanthanum
(1999)
Until recently, it was accepted that Ce 3+ cations, with an ionic radius (r) of 1.03 Å, were too large to form an ?-SiAlON structure. However, more-recent studies have shown that cerium cations can be incorporated into ...
