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 ...
Conformers of cis-N-methylacetamide : Ab initio study of geometries and vibrational spectra
(Elsevier, 1991-11-01)
Energies and geometries have been obtained, at the Hartree-Fock 4-31G* level, for the four stable conformers of cis-N-methylacetamide that result from conformational isomerism of the CH3 groups. Ab initio force fields were ...
Surface complexation models: An evaluation of model parameter estimation using FITEQL and oxide mineral titration data
(Elsevier, 1991-03-15)
The ability of surface complexation models (SCMs) to fit sets of titration data as a function of changes in model parameters was evaluated using FITEQL and acid-base titration data of [alpha]-FeOOH, [alpha]-Al2O3, and TiO2. ...
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 ...
A potential function for protein folding
(Kluwer Academic Publishers; J. C. Baltzer AG, Scientific Publishing Company ; Springer Science+Business Media, 1991-12)
One of the most difficult problems in computational chemistry is the prediction of the three-dimensional structure of a protein molecule given only its amino acid sequence. Although there are several programs for calculating ...
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 ...
Molecular cloning of porcine [alpha]1-microglobulin/HI-30 reveals developmental and tissue-specific expression of two variant messenger ribonucleic acids
(Elsevier, 1991-01-17)
A 1008 basepair (bp) cDNA clone encoding 335 amino acids followed by an inframe TGA translation termination codon and a 295-nucleotide 3' untranslated (UT) region has been isolated from a pig liver cDNA library. Based on ...
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 ...
