Magnetic, Mössbauer, and I.R. studies of nanosize particles of Fe and Co species dispersed in a cage of aluminosilicates structure, in relation to syngas (CO+H2) Fischer Tropsch conversion. The difference in the catalytic activity of such species have shown dependancy on their degree of dispersion. The carbonyl impregnation gave ultra-fine Super Paramagnetic Fe3O4, whereas the nitrate impregnat...

The kinetics of the reactions of 5'-AMP and 5'-GMP with excess cis-[Pt(NH,),CI,] in the presence of KCI at pH* 6.5 have been investigated by 'H NMR and analyzed by nonlinear numerical integration and optimization techniques. The species formed have been further characterized by 195Pt NMR. The reaction with 5'-AMP involves a branching pathway: 5'-AMP reacts with ~ i s [ P t ( N H ~ ) ~ c l , ] t...

oilseed rape is economically affected by stem rot caused by sclerotinia sclerotiorum worldwide. glucosinolates arethe specific secondary metabolites of brassica plants that appear in different profiles of each species. their hydrolysisproducts have biocidal activity and may play a role in resistance against plant pathogenic fungi. the resistance ofoilseed rape (brassica napus) cultivars and two...

Abstract We study reaction-diffusion processes with multi-species particles and hard-core interaction. add boundary driving to the system by means of external reservoirs which inject remove particles, thus creating stationary currents. consider condition that time evolution average occupation evolves as discretized version a coupled diffusive equations linear reactions. In particular, we identi...
