2,649,463 describes the production of a coordination complex created by the reaction of an olefin with a metal halide where the metal is copper, platinum, palladium, iridium, aluminum, zinc, silver, mercury or antimony. This coordination complex is further reacted with oxygen at a high ...
Hexavalent chromium (Cr(VI)) is still a common contaminant in water. In this work, we studied the Cr(VI) adsorption by polyphenol-rich bacterial cellulose(BC) gel, synthesized by the Komagataeibacter rhaeticus K15 using wine pomace. The results showed th
When the photosensitizing agent absorbs the light, it transfers the absorbed energy to oxygen molecules dissolved in the tissue producing an active oxygen molecules which destroy cells in the vicinity of the target cells where the agent has been localized. In the practice of the present invention,...
On the other hand, the 8 elements of Sr, Sn, Sb, Y, Zr, Nb, Mo and Ce form their oxides in LBE according to oxygen concentration. Iodine reacts with Pb and forms PbI2 under the almost given conditions, but it reacted with Rb and Sr to form either RbI and SrI2 under the ...

[0054] If the supported catalyst is used as a powder, the stirred container to be used for mixing the reaction components is fitted with stirrers which can be used for this purpose. When working with supported catalyst powders as a suspension in stirred vessels or bubble columns, amounts of...
it being possible for the carbon chain to be interrupted by nonadjacent oxygen, sulfur or NRa groups, with Ra=alkyl, cycloalkyl, aryl or aralkyl,x=0 to 2,and characterized in that(i) the compound (B) containing isocyanate groups and silane groups comprises uretdione groups, and(ii) the...
1. A sealant formulation prepared from components comprising: (a) at least one ungelled mercapto-terminated polymer prepared by reacting reactants comprising at least one polyvinyl ether monomer and at least one polythiol material; (b) at least one curing agent reactive with a mercapto group of...
These silver ions react with the citric acid and many silver ions produce a citric acid-silver complex while a very small quantity of silver ions is produced. On the other hand, the aluminum reacts with the citric acid and produces a citric acid-aluminum complex, and in addition to the ab...
