Low-temperature purification of gas streams from phenol by steam reforming over novel supported-Rh catalysts
(2010)
The purification of gas streams from phenol at low-temperatures (350-550 °C) was investigated by its reaction with steam over novel catalytic systems, namely 0.5 wt% Rh supported on Ce0.15Zr0.85O2, Ce0.15Zr0.83Mg0.02O2 and ...
Regiospecific Suzuki coupling of 3,5-dichloroisothiazole-4-carbonitrile
(2003)
3,5-Dichloroisothiazole-4-carbonitrile 1 reacts with aryl- and methylboronic acids to give in high yields the 3-chloro-5-(aryl and methyl)-isothiazole-4-carbonitrile 2 regiospecifically. The reaction was optimized with ...
1,2,3-Dithiazole chemistry in heterocyclic synthesis
(2006)
The chemistry of various 5H-1,2,3-dithiazoles is investigated with emphasis on assisted ring opening and ring closure reactions leading to new heterocycles. Thus on treatment with catalytic tetraalkylammonium iodide ...
Effects of sodium salts of lyotropic anions on low-temperature, ordered lipid monolayers
(2012)
Electrolytes are known to impart considerable disorder to lipid assemblies, including monolayers at the air-water interface, bilayers, and vesicles. In the present work, we have investigated the disordering effect of sodium ...
Preparation and surface characterisation of novel ceria-copper and ceria-manganese mixed oxides
(2002)
The paper presents surface texture and catalysis results for a series of copper and manganese-containing ceria samples. These samples, especially the 20% manganese containing one, had significantly higher surface area than ...
Suppression of the oxygen storage and release kinetics in Ce0.5Zr0.5O2 induced by P, Ca and Zn chemical poisoning
(2011)
The present investigation concerns for the first time the understanding of the individual and combined effects of phosphorous with calcium or zinc deposited on a Ce0.5Zr0.5O2 solid followed by calcination in 20%O2/He at ...
Effect of thermal aging on the transient kinetics of oxygen storage and release of commercial Cex Zr1-x O2-based solids
(2009)
The use of powerful analytical methodologies for the evaluation of the performance of commercial oxygen storage materials based on oxygen transient isothermal isotopic exchange experiments is illustrated in this study. Ce ...
A two-step reaction mechanism of oxygen release from Pd/CeO2: Mathematical modelling based on step gas concentration experiments
(2004)
A mathematical model was developed to study the transient release of oxygen from a 1 wt % Pd/CeO2 catalyst in the 450°-550°C range based on alternate step concentration switches between CO and O2. The proposed mathematical ...
The journey of L-tartaric acid in the world of enantiomerically pure bis- and trisadducts of C60with the inherently chiral trans-3 and all-trans-3 addition patterns
(2014)
Inherently chiral multi-adducts of [60]fullerene represent unique chiral molecular tectons featuring fascinating optoelectronic properties. Herein we discuss the most recent progress in the synthesis of enantiomerically ...
Spin-triplet excitons in 1,3-diphenyl-7-(fur-2-yl)-1,4-dihydro-1,2,4- benzotriazin-4-yl
(2013)
7-(Fur-2-yl)benzotriazinyl 1 is the first example of a hydrazyl radical dimer with a thermally accessible triplet state. The triplet exciton (|D| = 0.018 cm-1, |E| = 0.001 cm-1) was observed by solid-state VT-EPR spectroscopy ...
