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 ...
The steam reforming of phenol over natural calcite materials
(2009)
Five natural calcite materials of different geographical origin were studied towards the steam reforming of phenol reaction and the activity results obtained were correlated with some of their physico-chemical properties. ...
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) ...
Development of a Reliable Analytical Protocol for the Isolation of Cholesterol Oxidation Products—a Comparison of Different Lipid Extraction and Saponification Methods
(2015)
The main objectives of this study were (i) the optimization and the validation of a high performance liquid chromatographic method for the simultaneous determination of seven cholesterol oxidation products (COPs), (ii) the ...
Mathematical modeling of the oxygen storage capacity phenomenon studied by CO pulse transient experiments over Pd/CeO2 catalystAAA
(2003)
A mathematical model has been developed for the first time to study the oxygen storage capacity (OSC) phenomenon by the CO pulse injection technique over a 1 wt% Pd/CeO2 model catalyst in the 500-700°C range. A two-step ...
Low-temperature H2-SCR of NO on a novel Pt/MgO-CeO2 catalyst
(2007)
The selective catalytic reduction of NO by H2 under strongly oxidizing conditions (H2-SCR) in the low-temperature range of 100-200 °C has been studied over Pt supported on a series of metal oxides (e.g., La2O3, MgO, Y2O3, ...
Mechanistic aspects of the H2-SCR of NO on a Novel Pt/MgO-CeO2 catalyst
(2007)
Steady State Isotopic Transient Kinetic Analysis (SSITKA) coupled with Temperature-Programmed Surface Reaction (TPSR) experiments, using on line Mass Spectroscopy (MS) and in situ DRIFTS have been performed to study essential ...
Pt/Mg-Ce-O catalyst for NO/H2/O2 lean de-Nox reaction
(2004)
The NO/H2/O2 reaction was studied under oxidizing conditions in the 100-400 °C range over 0.1 wt% Pt supported on various metal oxides such as MgO, CeO2, SiO2, La2O3, CaO, Y2O3 and TiO2. The Pt/MgO and Pt/CeO2 catalysts ...
