Using steady-shear rheometry in combination with high-pressure 11B nuclear magnetic resonance spectroscopy (11B NMR), we have found that gels formed from water-soluble polymers containing vicinal hydroxyl groups cross-linked with various boron-contai

Ferromagnetic cobalt nanoparticles with average diameter of 9.5 nm, used for the purpose of magnetic catalyst recovery, were shown to catalyze the hydrolysis of silicon–hydride bonds for a range of hydrosilanes. The highest turnover frequencies (22

Thermodynamic parameters relevant to the phosphine-modified cobalt hydroformylation reaction are reported. Equilibrium constants for the hydrogenation of Co2(CO)6L2 to yield HCo(CO)3L were determined using in situ 1H and 31P NMR spectroscopy between

The dimeric cobalt complex Co 2 (CO) 6 [P(p-CF 3 C 6 H 4 ) 3 ] 2 (1) reacts reversibly with hydrogen to produce HCo(CO) 3 [P(p-CF 3 C 6 H 4 ) 3 ] (4). The carbonyl and the phosphine ligands of both 1 and 4 are very labile. Compound 1 reacts with CO t

High-pressure NMR spectroscopy was used for the first time to investigate microemulsions of water in supercritical carbon dioxide. The emulsions were formed using a family of anionic perfluoropolyether ammonium carboxylate surfactants. This system ho
