Synthesis and Application of Novel N-halamine Antimicrobial Materials
(2010-08-10)
Several novel antimicrobial N-halamines have been synthesized and were incorporated into water-soluble latex paint. These paints were expected to render good biocidal capability and the antimicrobial activity to be ...
Organic Electronic and Optoelectronic Devices Based on Diphenylamine End-group Polymers
(2010-12-01)
This work mainly focuses on making a series of organic diodes and photovoltaic devices based on electroconducting polymers with diphenylamine end-groups for their monomers. Most of them are with structural motif of R-X-R. ...
Smart Materials for Advanced Applications: Self-Decontaminating Polymers, Photofunctional Composites, and Electroconductive Fibers
(2010-12-17)
Materials capable of providing multifunctional properties controllable by some external stimulus (pH, light, temperature, etc) are highly desirable and obtainable given recent advancements in material science. Development ...
Purine Carbocyclic Nucleside Analogues as Antiviral Agents
(2010-12-07)
The carbocyclic nucleosides aristeromycin and neplanocin A are two of the most potent inhibitors of S-adenosylhomocysteine hydrolase, an enzyme that plays a critical role in methyl transfer reactions during a viral replication ...
Design and Synthesis of 3-Deazaaristeromycin Derivatives
(2010-12-07)
Analogs of naturally occurring nucleosides have served as structural models for the design of antitumor, antiviral, and antibacterial agents. The carbocyclic nucleosides aristeromycin and neplanocin A are two examples that ...
Production, Characterization and Structure Determination of the C-terminal Domain of Stt3p: the Catalytic Subunit of Yeast Oligosaccharyl Transferase
(2010-08-03)
N-glycosylation, the most ubiquitous protein modification in eukaryotes, is catalyzed by the enzyme complex Oligosaccharyl Transferase (OT). This protein co-translational modification has been implicated in a multitude of ...
Investigations of Laser Ablation and Laser-Induced-Plasma Ignition of Cyclotrimethylenetrinitramine (RDX)
(2011-01-04)
Performance and sensitivity are two factors almost equally weighed when an explosive is considered in application. With a superb combination of high detonation power and low sensitivity to external stimuli, secondary ...
The Identification of Critical Active-Site Groups and Catalytic Steps Governing the Desulfonation Reaction by Alkanesulfonate Monooxygenase
(2012-10-08)
The alkanesulfonate monooxygenase enzyme (SsuD) catalyzes the oxygenolytic cleavage of a carbon-sulfur bond of sulfonated substrates. A mechanism involving acid-base catalysis is proposed for the desulfonation mechanism ...
A Novel Halogenation Protocol and Non-heme Iron Hydroxylase Mimics as Catalysts for C-H Oxidation and O2 Activation
(2012-08-03)
Hydrocarbons react with molar concentrations of peracetic acid and halide salts to yield predominantly monohalogenated products under optimum conditions, with chlorination being more oxidatively efficient than bromination. ...
Regioselectivity of the Photoisomerization of Acyclic 1,3-Dienes and Stable Trans Cycloheptenes
(2012-12-05)
There is still no complete understanding of how the visual system controls the
regioselectivity of the photoisomerization of the C11=C12 double bond in the visual
chromophore retinal. In this work we used a series of ...
