Advances in predicting organic contaminant abatement during ozonation of municipal wastewater effluent: reaction kinetics, transformation products, and changes of biological effects

Ozonation of municipal wastewater effluent has been considered in recent years as an enhanced wastewater treatment technology to abate trace organic contaminants (micropollutants). The efficiency of ozonation for micropollutant abatement depends on (1) the ...

Spherical superstructures of oxide nanoparticles for catalytic reactions in microchemical reactors

Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker

We report the fabrication of spherical superstructures composed of SiO2 and TiO2 nanoparticles and their applications in catalyzing organic reactions. Assembling of the nanoparticles into superstructures is done by heating a water-in-oil micro-emulsion, wh ...

How to increase the selectivity of Pd-based catalyst in alkynol hydrogenation: Effect of second metal

Lioubov Kiwi, Duncan Thomas Lindsay Alexander, Fernando Cardenas Lizana, Artur Yarulin

The development of selective Pd-based catalyst for semi-hydrogenation of dehydroisophytol (DIP), a C20-alkynol, is reported. A series of unsupported mono- (Pd) and bimetallic (Pd-M) nanoparticles (NPs) with Pd/M molar ratios of 1.5 - 5.0 (M = Ag or Cu) wer ...

Direct Evaluation of the Hyperconjugative Interactions in 1,1,1-Trihaloethane (CH3CX3, X = F, Cl, and Br)

Zhenhua Chen

Following the computational strategy proposed by Mulliken in 1939 (J. Chem. Phys. 1939, 7 (5), 339-352), when the concept of hyperconjugation was coined, we evaluated the hyperconjugative stabilization energy in 1,1,1-trihaloethane using the block-localize ...

Novel Approaches for Ruthenium Catalyzed Atom Transfer Radical Addition Reactions

Katrin Anne Thommes

A new catalytic procedure for atom-transfer radical addition (ATRA) and cyclization (ATRC) reactions is described. The combination of the ruthenium(III) complex [RuCl2Cp*(PPh3)] with magnesium allows these reactions to be performed under mild conditions wi ...

Electron Capture Dissociation Product Ion Abundances at the X Amino Acid in RAAAA-X-AAAAK Peptides Correlate with Amino Acid Polarity and Radical Stability

Yury Tsybin, Hisham Ben Hamidane, Aleksey Vorobyev

We present mechanistic studies aimed at improving the understanding of the product ion formation rules in electron capture dissociation (ECD) of peptides and proteins in Fourier transform ion cyclotron resonance mass spectrometry. In particular, we attempt ...

Novel catalytic applications of carbon nanofibers on sintered metal fibers filters as structured supports

Marina Ruta

Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...

Excited-State Dynamics of Donor−Acceptor Bridged Systems Containing a Boron−Dipyrromethene Chromophore: Interplay between Charge Separation and Reorientational Motion

Natalie Renuka Banerji, Eric Vauthey

The excited-state dynamics of a series of electron donor−acceptor bridged systems (DABS) consisting of a boron−dipyrromethene chromophore covalently linked to a dinitro-substituted triptycene has been investigated using femtosecond time-resolved spectrosco ...

New polynuclear catalysts for atom-transfer radical addition reactions

Laurent Quebatte

Homo- and heterobimetallic complexes of the late transitions metals have been synthesized by metathesis reactions of the corresponding chloro-bridged dimers. These reactions have the advantage of being fast and giving rise to structurally defined products ...

A bimetallic ruthenium ethylene complex as a catalyst precursor for the Kharasch reaction

Kay Severin, Euro Solari, Laurent Quebatte

A bimetallic complex, in which a RuCl2 (eta(2)C(2)H(4))(PCy3) fragment is connected via three chloro, bridges to a (eta(6)-p-cymene)RuCl2 fragment, has been synthesized and characterized by single-crystal X-ray crystallography. This complex was used to cat ...
