Tris(1,3-Dihydroxy-2-propyl)amine, A Planar Trialkylamine: Synthesis, Structure, and Properties. A Potential Precursor to Hypervalent Nitrogen
(2008-09-09)
The hindered amine tris(1,3-dihydroxy-2-propyl)amine, 36, is a potential precursor to possible examples of nitrogen hypervalency. There are no simple, effective, and general methods to synthesize hindered tertiary amines. ...
The Synthesis and Practical Applications of Novel N-Halamine Biocides
(2009-02-23)
A novel set of N-halamine siloxane precursors were synthesized for the purpose of coating various substrates to determine the factors, which are the most dominant influences of the overall stability of the newly modified ...
Elucidating the flavin reductase mechanism in the alkanesulfonate monooxygenase system from Escherichia coli
(2009-02-23)
The two-component alkanesulfonate monooxygenase system from Escherichia coli is comprised of an FMN reductase (SsuE) and a monooxygenase enzyme (SsuD) that together catalyze the oxidation of alkanesulfonate to the corresponding ...
Design and Properties of Novel Uranium-Containing Layered and Framework Materials
(2008-09-09)
Ten uranyl-containing frameworks and one layered material have been
synthesized under hydrothermal conditions. These compounds belong to eight structure
types, not previously described. They are constructed from uranyl ...
Roles of an 'Inactive' Domain in Catalase-Peroxidase Catalysis: Modulation of Active Site Architecture and Function by Gene Duplication
(2008-09-09)
Within biological systems iron is a transition metal that allows access to the benefits of molecular oxygen as an oxidant. However, with these benefits come grave consequences if the reactions are not strictly controlled. ...
Ion Selective Polymeric Membranes as Chemically Selective Coulometric Electrodes
(2008-09-09)
Potentiometric and optical ion sensors use highly selective lipophilic ionophores as a special additive in a plasticized PVC membrane have been thoroughly studied for application as a coulometric electrode. This dissertation ...
Quantum Chemical Studies and Kinetics of Gas Reactions
(2008-09-09)
Potential energy surfaces and reaction mechanisms were calculated using various computational methods such as density-functional and wave-function methods. High-level computational methods were used to obtain accurate ...
Characterization of the iron center in cysteine dioxygenase and kinetic analyses of flavin binding by the alkanesulfonate flavin reductase
(2008-09-09)
Cysteine dioxygenase (CDO) and the flavin reductase, SsuE, are both important proteins in sulfur metabolism. CDO catalyzes cysteine oxidation which is a key step in cysteine metabolism in mammalian systems. SsuE is a flavin ...
Studies on Laser Ablation of Polymer Coated Propellant Films
(2008-09-09)
In artillery, safety issues make propellants highly preferable as compared to ordinary explosives. However, the same properties that make propellants safer, such as their low shock sensitivities, also make them more difficult ...
Studies on The Synthesis of B-Ring 6-Azasteroids
(2008-09-09)
Azasteroids, which carry a nitrogen in the C-6 position of the steroid nucleus are still
mysterious and very few synthesized, were found to possess antimicrobial and antifungal
properties apart from their pharmacodynamic ...
