This thesis deals with a laboratory study of heterogeneous reactions involving bromine and chlorine containing reservoir species on alkali salt substrates which are relevant to the marine boundary layer, and on ice substrates which are relevant to the lowe ...
The water-soluble Ru(II)-phosphine complex, [{RuCl2(mTPPMS)(2)}(2)] was found a suitable catalyst for the hydrogenation of NaHCO3 to NaHCO2 in aqueous solution under mild conditions with catalyst turnover frequencies (TOFs) in the range of 35-50 h(-1) at 5 ...
Reaction kinetics and catalyst deactivation during the redn. of NO with CO on a 0.5%Pt-3.4%MoO3/a-Al2O3 catalyst were investigated. The reaction shows an ignition/quenching behavior. After ignition, the reaction kinetics (formation of N2 and N2O) obey the ...
The present invention relates to an apparatus and a method of fabricating the apparatus for dispensing a sample for subsequent analysis by mass spectrometry. The apparatus comprises a polymer substrate (1), in which a covered microchannel (3) has been etch ...
We have investigated different possible mechanisms for the cis-trans isomerization in triply bonded ditungsten complexes with stoichiometry W2Cl4(NHEt)2(PMe3)2 using static d. functional calcns. as well as Car-Parrinello simulations. Our studies reveal an ...
The present work deals with two subjects. The interaction of NO2 and HONO with different types of soot are examined in the first part whereas in the second part an experimental set-up is presented which has been built in order to measure the kinetics of th ...
The degrdn. of herbicides 4-chlorophenoxyacetic acid (4-CPA), 4-chloro-2-methylphenoxyacetic acid (MCPA), 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) in aq. medium of pH 3.0 was comparatively studied by anodic oxi ...
The aim of this work has been to design, and fabricate a miniaturized electrospray-type interface for mass spectrometry analysis, which allows the nebulization of solutions by applying a high potential difference between the source and the mass spectromete ...
One-step hydroxylation of benzene to phenol by N2O has been performed over structured catalytic beds made of ZSM-5 coatings on stainless steel grids. The catalysts demonstrated high activity with a selectivity toward phenol formation of 98%. A detailed kin ...
A method for the online calcn. of conversion rates and yield coeffs. under dynamic process conditions was developed. The method is based on cumulated mass balances using a moving av. method. Elemental balances were used to test the measured cumulated quant ...
