Influence of oxychlorination treatments on the redox and oxygen storage and release properties of thermally aged Pd-Rh/CexZr1-xO 2/Al2O3 model three-way catalysts
(2005)
Model Pd-Rh/Al2O3 three-way catalysts with and without CexZr1-xO2 as oxygen storage component have been compared in their fresh, thermally aged and oxychlorinated treated surface states to determine the potential regenerating ...
Synthesis and characterization of polyampholytic model networks: Effects of polymer composition and architecture
(2002)
Synthesis and characterization of polyampholytic model networks were studied using group transfer polymerization (GTP). The degrees of swelling (DSs) of all the polyampholytic networks were also measured as a function of ...
Effects of hofmeister anions on DPPC langmuir monolayers at the air-water interface
(2004)
In this work we investigated the effect of sodium salts of different monovalent anions belonging to the Hofmeister series on Langmuir monolayers of DPPC (1,2-dipalmitoyl phosphatidylcholine). The salts used were NaCl, NaBr, ...
Effect of halogen substitution on p-phenylenebiscarbene
(2005)
The effect of halogen (F, Cl, and Br) perturbation on the geometries and relative energies of five electronic states (one quintet, two triplets, and two singlets) of p-phenylenebiscarbene (1-H) was examined computationally ...
Effect of halogen substitution on o-Phenylenebiscarbene
(2005)
The effect of halogen (F, Cl and Br) perturbation on the geometries and relative energies of five electronic states (one quintet, two triplets and two singlets) of o-phenylenebiscarbene (1-H) is examined computationally ...
Time resolved infrared absorption studies of geminate recombination and vibrational relaxation in OCIO photochemistry
(2004)
The first ultrafast time-resolved infrared absorption studies of the geminate recombination and vibrational relaxation dynamics of aqueous chlorine dioxide (OCIO) were presented. The rapid increase in optical density ...
SAXS Investigation of ABC Triblock Star Terpolymers in Aqueous Solution
(2004)
The structure of three different ABC triblock star terpolymers in aqueous solution has been investigated by small-angle x-ray scattering (SAXS). The form factor was modeled using an analytical expression for a Gaussian ...
Can we use area per surfactant as a quantitative test model of specific ion effects?
(2004)
The three main currently proposed approaches for understanding specific ion effects are briefly described. In some experimentally well defined and simplified situations, one can decouple ion specificity effects from all ...
Synthesis and characterization of star polymers and cross-linked star polymer model networks containing a novel, silicon-based, hydrolyzable cross-linker
(2004)
An acid-labile dimethacrylate cross-linker, dimethyldi(methacryloyloxy-1-ethoxy)silane (DMDMAES), was synthesized by the reaction of 2-hydroxyethyl methacrylate (HEMA) and dichlorodimethylsilane in the presence of ...
Speed selection mechanism for propagating fronts in reaction-diffusion systems with multiple fields
(2002)
We introduce a speed selection mechanism for front propagation in reaction-diffusion systems with multiple fields. This mechanism applies to pulled and pushed fronts alike, and operates by restricting the fields to large ...
