Численная гидродинамическая модель атмосферной дисперсии загрязнений вокруг зданий

The computational fluid mechanics model of is atmospheric dispersion in the vicinity of buildings is developed. The validation of model against field experiment was performed. The application of model to problem of estimation of concentration near contaminated buildings located at the territory of Pridneprovsky Chemical Plant is presented

Chemo-enzymatic cascade oxidation in supercritical carbon dioxide/water biphasic media

Enantioselective sulfoxidation was carried out by cascade reaction of Pd(0) catalysed formation of H2O2 and enzymatic oxidation using chloroperoxidase from Caldariomyces fumago. Supercritical carbon dioxide (scCO(2)) was used as medium for in situ generation of H2O2 directly from H-2 and O-2 using Pd-catalysts. Subsequently, H2O2 was utilised by the chloroperoxidase as an oxidant for the asymmetric sulfoxidation in the aqueous phase. This chemo-enzymatic cascade transformation exemplifies the potential of compartmentalisation of catalytic processes in multiphase systems
