Highly stereoselective preparation of nitro olefins and nitro dienes by the addition-elimination of copper-zinc organometallics to [beta]-alkylthio and [beta]-phenylsulfonyl nitro olefins
(Elsevier, 1991-01-21)
The addition-elimination of copper-zinc organometallics RCu(CN)ZnX to (E)-1-nitro-2-phenylsulfonyl ethylene 2a gave highly functionalized pure (E) nitro olefins and stereoselectively (1E, 3E) and (1E, 3Z)-1-nitrodienes in ...
Fat-preferring rats consume more alcohol than carbohydrate-preferring rats
(Elsevier, 1991)
Rats with a genetic preference for alcohol (ETOH) have been found to consume more dietary fat then ETOH nonpreferring rats. We therefore hypothesized that rats selected on the basis of fat and carbohydrate (CHO) preferences ...
The selectivity of hydrazine oxidation on a polycrystalline rhodium surface
(Elsevier, 1991-11-02)
The surface reactions of coadsorbed hydrazine and atomic oxygen have been examined by means of temperature-programmed reaction spectroscopy (TPRS) on a clean polycrystalline rhodium surface over the 90 to 1450 K temperature ...
Monte Carlo simulation of the adsorption of co on pt(111): thermodynamic considerations for the surface configuration of adsorbed species
(Elsevier, 1991-02-02)
We have developed a "two-site" lattice gas model which provides a theoretical framework for understanding adsorption equilibrium in systems for which the potential energy surface is inherently heterogeneous in terms of ...
Comparison of the isolation of adducts fo 2'-deoxycytidine and 2'-deoxyguanosine with phenylglycidyl ether by high-performance liquid chromatography on a reversed-phase column and a polystyrene-divinylbenzene column
(Elsevier, 1991)
2'-Deoxycitidine (dCyd) and 2'-deoxyguanosine (dGuo) were subjected to reaction with phenylglycidyl ether (PGE) in methanol in order to study the formation of the corresponding 2'-deoxynucleoside adducts. Separation methods ...
Interaction of fatty acids with recombinant rat intestinal and liver fatty acid-binding proteins
(Elsevier, 1991-04)
Intestinal enterocytes contain two homologous fatty acid-binding proteins, intestinal fatty acid-binding protein (I-FABP)2 and liver fatty acid-binding protein (L-FABP). Since the functional basis for this multiplicity is ...
Modeling of immunosensors under nonequilibrium conditions : I. Mathematic modeling of performance characteristics
(Elsevier, 1991-08-01)
Immunosensors for the detection of small analytes that use analyte-enzyme conjugates as signal generators require special attention if operated under nonequilibrium conditions. If the size of the analyte and the analyte-enzyme ...
Structural and kinetic studies in propene oxidation over Sb oxide dispersed on TiO2
(Elsevier, 1991-02)
Antimony oxide dispersed on TiO2 was characterized using FTIR, Raman, and Auger spectroscopies as well as XRD. They indicate that the electronic environment about Sb is perturbed at low concentration suggesting that the ...
