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 ...
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 ...
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 ...
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 ...
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 ...
Manipulating the singlet-triplet energy gaps of arene-fused bis(1,2,3-dithiazoles): A computational study
(2013)
Benzo- and azino-fused bis(1,2,3-dithiazoles) were investigated computationally using density functional theory (DFT) in an attempt to relate structure to ground state multiplicity preference. Structural changes on the ...
Separation of acetylcholinesterase inhibitors using polymeric surfactants in polyelectrolyte multilayer coatings
(2012)
The main objective of this study is the use of polymeric surfactants in polyelectrolyte multilayer (PEM) coatings for the separation of the pharmaceutical substances acetylcholinesterase inhibitors (AChEIs). AChEIs are ...
Tetraphenylhexaazaanthracenes: 16π Weakly Antiaromatic Species with Singlet Ground States
(2015)
Tetraphenylhexaazaanthracene, TPHA-1, is a fluorescent zwitterionic biscyanine with a closed-shell singlet ground state. TPHA-1 overcomes its weak 16π antiaromaticity by partitioning its π system into 6π positive and 10π ...
Uranium determination in water samples by liquid scintillation counting after cloud point extraction
(2010)
The aim of this study is the radiometric determination of uranium in waters by liquid scintillation counting (LSC) after pre-concentration of the element by cloud point extraction (CPE). For CPE, tributyl phosphate (TBP) ...
