Hydrolysis and hydrogenation of [RhCl(tppms)(3)] (1) and trans-[RhCl(CO)(tppms(2)] (2) was studied in aqueous solutions in a wide pH range (2 < pH < 11) in the presence of excess TPPMS (3 -diphenylphosphinyl-benzenesulfonic acid sodium salt). In acidic sol ...
Structured filamentous zeolitic materials were prepd. by depositing ZSM-5 coatings on glass fiber supports. A homogeneous coverage of the support filaments was obtained by prepg. MFI crystals in F-contg. media at neutral pH. The samples were characterized ...
The reactivity of hypoiodous acid (HOI) is an important factor for the fate of iodine in oxidative drinking water treatment. The possible reactions of HOI are its disproportionation, its oxidation to iodate (IO3-), or the reaction with natural organic matt ...
The solid-state structure of the cationic MeO-Biphep Rh(I) compd. [Rh((S)-MeO-Biphep)(P{OMe}3)2]BF4 (3) was detd. by x-ray diffraction. The four P-donors deviate markedly from square-planar geometry, with the phosphite ligands P2 and P2' ca. +-0.61(7) .ANG ...
In aqueous solutions, RuCl2(TPPMS)(2) (TPPMS = 3-sulfonatophenyldiphenylphosphine) catalyzes the exchange between H-2 and D2O or between D-4 and H2O with high efficiency (up to 1 252 turnovers per hour) under mild conditions (298 K, 2 MPa H-2). The ex ...
An agitated 12-well microtiter plate system with a working volume of 2ml was investigated for cell culture process development. Agitation assures homogeneity in wells and enhances mass transfer between the gas and the liquid phase, thus improving maximum c ...
Previous studies of cyanide exchange on square planar tetracyanoplatinate complex [Pt(CN)4]2- have been undertaken only at a high pH. For a more complete fundamental understanding of this system we extended the investigations of these exchanges over a larg ...
A Multicomponent Aerosol Dynamics Model (MADM) capable of solving the condensation/evaporation equation of atmospheric aerosols is presented. Condensable species may be organic and/or inorganic. For the inorganic constituents the equilibrium model ISORROPI ...
The water-soluble tertiary phosphine complex of ruthenium(II), [RuCl2(PTA)(4)], (PTA. 1,3,5-triaza-7-phosphaadamantane) was used as catalyst precursor for hydrogenation of CO2 and bicarbonate in aqueous solution, in the absence of amine or other additives, ...
Protoporphyrin IX (PpIX) is used as a fluorescence marker and photosensitizing agent in photodynamic therapy (PDT). A temporary increase of PpIX in tissues can be obtained by administration of 5-aminolevulinic acid (ALA). Lipophilicity is one of the key pa ...
