Good understanding of the different phases of involved plasma-chemistry is essential for the development of non thermal plasma technologies for pollution control. These techniques are often based on the production of radicals from dissociation parent gases ...
Bromate formation in ozone-based advanced oxidation processes (AOPs) was investigated by laboratory experiments in combination with kinetic modeling. Oxidant concentrations were monitored during the experiments, which allows us to account for the relative ...
Ozone prodn. in 5M H2SO4 with Ti/IrO2/SnO2 - Sb2O5 electrodes was studied. Electrodes were prepd. at 550 Deg by spray pyrolysis of a soln. of precursors contg. tin and antimony chlorides. The aim of this work was to elucidate the mechanism of activation an ...
After an experimental study of refrigerants HFC-134a, HCFC-123, HFC- 404A and HFC-407C, and considerable modifications to the test stand, LENI has undertaken a new experimental program and has assembled a large new database for evaporation of ammonia and t ...
From a data set collected during the MEDCAPHOT-TRACE field campaign, we demonstrate that ozone fluxes can be detd. with a shot-per-shot DIAL instrument operated in the UV spectral region. This is done by the simultaneous reconstruction of ozone concns. and ...
The reaction between the hydroxyl radical and the nitrogen dioxide radical in the gas phase has been studied with ab initio mol. dynamics simulations based on d. functional theory. Nitric acid HONO2 and cis-cis peroxynitrous acid ONOOH are formed spontaneo ...
Triacetate of 7-oxabicyclo[2.2.1]hept-5-ene-1,2-exo,3-exo-trimethanol was converted selectively into (1RS,2SR,5RS,6RS)-4,5,6-tris(acetoxymethyl)-2-bromocyclohex-3-en-1-ol (4) or into (1RS,2SR,5RS,6RS)-5,6-bis(acetoxymethyl)-2-bromo-4-bromomethylcyclohex-3 ...
Intube evaporation tests for R-407C and R-407C/oil are reported for a plain copper tube. The tests were run at a nominal inlet pressure of 6.45 bar (93.5 psia) at mass velocities of 100, 200 and 300 kg/m2s (73581, 147162 and 220743 lb/h ft2) over nearly th ...
The objectives of the present work is to theoretically and experimentally demonstrate the advantages of a two-stage cycle equipped with an economizer and single variable speed compressor for heat pumps using air as cold source. Furthermore, an efficient de ...
Zinc(II) phthalocyanine (ZnPC) is a new photosensitizer currently undergoing phase I and II clinical trials at Lausanne's CHUV hospital for the photodynamic therapy (PDT) of early cancer in the upper aerodigestive tract. Activated oxygen species other than ...
