Characterization of the electrode/electrolyte interphase of the electronically conducting polymer, polypyrrole
(1990)
An investigation was made to characterize the structure of the interphase of polypyrrole in terms of semiconductor theory and the molecular structure of the polymer. This investigation was carried out by performing experiments ...
Overproduction and utilization of enzymes in synthetic organic chemistry
(1989)
The utility of papain in the synthesis of peptides containing D or unusual amino acids has been demonstrated. A novel one-step synthesis of tripeptides has been developed using papain. The amidase activity of a number of ...
Transition metal complexes with substituted 7-azaindoles
(1990)
New convenient synthetic routes into mononuclear and dinuclear transition metal complexes with the ligand α-carboline are described. In addition, a new high yield preparative route for α-carboline is presented. Several ...
Proton solid-state nuclear magnetic resonance studies of zeolite catalysts
(1992)
Zeolites are inorganic solid acids which arc important in many industrial heterogeneous catalysis processes involving chemical transformations of hydrocarbons. The Bronsted acidity of a particular zeolite determines its ...
Silyl group transfer cyclizations
(1992)
An intermolecular-intramolecular Michael reaction sequence was developed for the synthesis of cyclopentanes and cyclohexanes. Silyl ketene acetals and silyl enol ethers were used as the nucleophilic initiators of the ring ...
Study of structural and physical properties of early transition metal chalcogenides and halides
(1995)
Many tantalum and niobium rich chalcogenides have been synthesized and because of their interesting anisotropic structures and properties, the physical properties of these compounds have been studied. The group V metal-rich ...
Ligand effects on the organometallic chemistry of nickel
(1993)
Nickel complexes in sulfur-rich environments have been prepared to determine those factors which stabilize organonickel species and permit access to low valent nickel. Nickel tetrathiolate complexes were initially used as ...
Mechanistic and structural investigations of decarboxylation reactions
(1993)
The utilization of carbon dioxide as a C1 source for the production of organic substrates presents a great challenge to researchers. One such process would be the carboxylation of hydrocarbons to afford carboxylic acids. ...
The role of copper(1) in homogeneously catalyzed decarboxylation reactions of carboxylic acids
(1993)
Heterobimetallics of the form (L2)CuCo(CO)4 were found to be catalyst precursors for the decarboxylation of NCCH2CO2H. The rate of decarboxylation is affected by the donating ability of the L2 ligand, i.e., more basic ...
The X-ray crystal structure of bovine (gamma symbol)-carboxypeptidase A
(1986)
The structure of [gamma]-carboxypeptidase A from bovine pancreas has been determined by single-crystal X-ray crystallography at 2.0 [angstrom] with a final Residual R factor of 0.250. Multiple isomorphous replacement, an ...
