The effects of P-poisoning of CexZr1-xO2 on the transient oxygen storage and release kinetics
(2013)
The present work reports on the investigation of the effects of chemical poisoning of CexZr1-xO2 solids by phosphorous (P) on the kinetics of oxygen storage and release (OSR) of the thus derived P-contaminated solids, as ...
A magnetostructural investigation of an abrupt spin transition for 1-phenyl-3-trifluoromethyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl
(2014)
1-Phenyl-3-trifluoromethyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl is the first example of a hydrazyl radical that shows a reversible sharp spin transition fully completed within 5(1) K. The nominally first-order transition ...
Structural, magnetic, and computational correlations of some imidazolo-fused 1,2,4-benzotriazinyl radicals
(2014)
1,3,7,8-Tetraphenyl-4,8-dihydro-1H-imidazolo[4,5g][1,2,4]benzotriazin-4-yl (5), 8-(4-bromophenyl)-1,3,7-triphenyl-4,8-dihydro-1H-imidazolo[4,5g][1,2,4] benzotriazin-4-yl (6), and 8-(4-methoxyphenyl)-1,3,7-triphenyl-4,8-dihydro-1H- ...
The suppression of columnar π-stacking in 3-adamantyl-1-phenyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl
(2016)
3-Adamantyl-1-phenyl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yl(4) crystallizes as chains of radicals where the spin bearing benzotriazinyl moieties are isolated from each other. Magnetic susceptibility studies in the 5-300 K ...
Low-temperature conversion of phenol into CO, CO 2 and H 2 by steam reforming over La-containing supported Rh catalysts
(2012)
The steam reforming of phenol in the low-temperature range of 350-550°C was studied over 0.5wt% Rh supported on Ce 0.15Zr 0.85O 2, Zr 0.93La 0.07O 2, and Ce 0.13Zr 0.83La 0.04O 2 mixed metal oxides. The reforming specific ...
Deactivation of Pd/Ce 0.5Zr 0.5O 2 model three-way catalyst by P, Ca and Zn deposition
(2012)
The negative effects of P, P-Ca and P-Zn deposition on the surface of a model 1wt% Pd/Ce 0.5Zr 0.5O 2 " three-way" catalyst (TWC) on its structural, morphological, textural, oxygen storage and release, and catalytic ...
Antiferromagnetic interactions in 1D Heisenberg linear chains of 7-(4-fluorophenyl) and 7-phenyl-substituted 1,3-diphenyl-1,4-dihydro- 1,2,4-benzotriazin-4-yl radicals
(2012)
7-(4-Fluorophenyl) and 7-phenyl-substituted 1,3-diphenyl-1,4-dihydro-1,2,4- benzotriazin-4-yl radicals were characterized by X-ray diffraction analysis and variable-temperature magnetic susceptibility studies. The radicals ...
Synthesis of 7-aryl/heteraryl-1,3-diphenyl-1,2,4-benzotriazinyls via palladium catalyzed Stille and Suzuki-Miyaura reactions
(2011)
Stille and Suzuki-Miyaura reactions of 7-iodo-1,3-diphenyl-1,4-dihydro-1,2, 4-benzotriazin-4-yl are presented as rare examples of cross-coupling reactions with stable organic radicals. Both the Stille and Suzuki-Miyaura ...
Ferromagnetic interactions in a 1d alternating linear chain of π-stacked 1,3-diphenyl-7-(thien-2-yl)-1,4-dihydro-1,2,4-benzotriazin-4-yl radicals
(2012)
X-ray studies show that 1,3-diphenyl-7-(thien-2-yl)-1,4-dihydro-1,2,4- benzotriazin-4-yl (6) adopts a distorted, slipped π-stacked structure of centrosymmetric dimers with alternate short and long interplanar distances ...
Regular and inverse polyampholyte hydrogels: A detailed comparison
(2016)
Two series of polyampholyte (PA) hydrogels were prepared via reversible addition-fragmentation chain transfer polymerization, followed by removal of the protecting group of the acidic monomer repeating units (methacrylic ...
