Enantiomerically pure 2,8-diazabicyclo[3.2.1]oct-2-ene derivatives (+)-5 and (-)-5 have been obtained from 2-azido-3-tosyl-7-azabicyclo[2.2.1]heptanes (+)-1 and (-)-2 and their enantiomers, by ring expansion under radical conditions. Compounds (+)-5 and (- ...
The electro-combustion of water sol. polymeric contaminants such as polyacrylates (PA) in aq. acid soln. using a B-doped diamond anode was studied by bulk electrolysis in 1 mol/dm3 HClO4 under galvanostatic conditions in a wide range of PA concns. and curr ...
A review, with 17 refs., on research carried out by the polymer reaction engineering group at EPFL in reaction engineering, including kinetic modeling of polymn. reactions (lab. and pilot scale reactors), free radical, polyepoxydation, polycondensation. De ...
When wetting is promoted by interfaces, the rate at which the liquid spreads over the solid substrate is controlled by the rate at which the well-wetted interfacial product can be formed along the liquid/solid/atmospheric triple line. If this reaction invo ...
[Pt-3(mu-CO)(3)(PPh3)(3)] was prepared in high yield by the reaction of [Pt-3(mu-CO)(3)(PPh3)(4)] with H2O2. The carbonyl ligands in [Pt-3(mu-CO)(3)(PR3)(3)] (PR3 = PPh3, PPh(2)Bz, PCy3, P'Pr-3) may be completely replaced by sulfur dioxide to give [Pt-3(mu ...
The present study investigates the degradation of atrazine (2-chloro-4-(ethylamino)-6-isopropylamino-s-triazine) by ozone and OH radicals during ozonation and advanced oxidation processes, with the identification of the main degradation products. Besides t ...

Advanced oxidation has proven to be an efficient process to increase micropollutant removal compared to conventional ozonation and to lower considerably the load to subsequent activated carbon treatment. Laboratory tests to determine the most important rea ...

PEG-diacrylamide was synthesized and utilized to make materials for tissue engineering. Acrylamide groups readily react with thiol groups, and peptides containing a single thiol group were coupled to the PEG-diacrylamide in aqueous solution at room tempera ...
The authors have studied the electrochem. oxidn. of H2SO4 on B-doped synthetic diamond electrodes (BDD) obtained by hot filament CVD on p-Si. High current efficiency for H2SO4 oxidn. to peroxodisulfuric acid can be achieved in concd. H2SO4 (>2M) at moderat ...
