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 ...
Efficient in-situ regeneration method of the catalytic activity of aged TWC
(2007)
The expansion of durability of deactivated "three-way" catalysts (TWCs) used in gasoline-driven cars by applying efficient, economically viable and environmentally friendly methods for the in situ regeneration of their ...
Regio- and stereoselective synthesis of enantiomerically pure [60]fullerene tris-adducts with an inherently chiral e,e,e addition pattern
(2005)
The synthesis and flash column chromatographic separation of c enantiomerically pure tris-adducts of C60 with an e,e,e-addition pattern is achieved via cyclopropanation with chiral D3-symmetrical cyclo-tris(malonate) ...
[4 + 2] Cycloadditions of rigid s-cis dienes to C60. A synchronous Diels-Alder reaction
(2001)
(Matrix presented) The Diels-Alder reaction of rigid s-cis dienes with C60 occurs by a concerted mechanism, via a symmetrical transition state.
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 ...
A DFT study of the ground state multiplicities of linear vs angular polyheteroacenes
(2004)
Unrestricted density functional calculations in combination with the broken-symmetry approach and spin-projection methods have been employed to study a series of formally 4n π antiaromatic linear and angular polyheteroacenes. ...
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 ...
Catalytic removal of nitrates from waters
(2010)
The selective catalytic reduction of nitrates (NO3 -) in pure water towards N2 formation by the use of gaseous H2 and in the presence of O2 (air) at 1 atm total pressure and 25 °C has been investigated over Pd-Cu supported ...
