In this case, reaction of hexahedral silsesquioxane and CF 3 SO 3 H in DMSO conducted in 1 : 12 molar ratio gives heptahedral silsesquioxane. In the first step CF 3 SO 3 H acid attacks siloxane Si-O-Si bonds and the formation of Si-O-SO 2 CF 3 bond parallel with cage opening process is observed and compound B is obtained (Figure below). Such an ...
Gillette is an American brand of safety razors and other personal care products including shaving supplies, owned by the multi-national corporation Procter & Gamble (P&G). ). Based in Boston, Massachusetts, United States, it was owned by The Gillette Company, a supplier of products under various brands until that company merged into P&G i
Caesium hydride or cesium hydride is an inorganic compound of caesium and hydrogen with the chemical formula Cs H.It is an alkali metal hydride.It was the first substance to be created by light-induced particle formation in metal vapor, [2] and showed promise in early studies of an ion propulsion system using caesium.

This is the list of Schedule I controlled substances in the United States as defined by the Controlled Substances Act. [1] The following findings are required for substances to be placed in this schedule: [2]
methanol - 0.8 ethanol - 1.4 propanol - 2.7 pentanol - 2.8 acetone - 1.4 toluene - 7.6 cyclohexanone - 7.0 hexane - 2.4 Recent studies have determined the volume viscosity for a variety of gases, including carbon dioxide , methane , and nitrous oxide .
For all A P H 4 systems in D 4h symmetry, the ground state is a 1g. The exact electronic configuration, however, is dependent on the electronegativity of the main group element. The distortion to tetrahedral geometry has b 2u symmetry. For these A P H 4 systems, the a 2u →b 1g * and e u →e g * one-electron charge-transfer transitions are ...
The 17 wallpaper groups, with finite fundamental domains, are given by International notation, orbifold notation, and Coxeter notation, classified by the 5 Bravais lattices in the plane: square, oblique (parallelogrammatic), hexagonal (equilateral triangular), rectangular (centered rhombic), and rhombic (centered rectangular).
