Therefore, in the incident energy region where the shape resonance is present for only one of the spin-speciic scattering channels, the difference between the

The aim of this work was the development of a green analytical procedure for determination of copper and iron in plant materials, exploiting microwave-assisted digestion with

Novel 1,4’-bipyrazoles were synthesized via highly regioselective cyclocondensation reactions of β -dimethylaminoenones with hydrazine monohydrate, tert -butylhydrazine

First, a univariate study of the Zn-Ox complex peak current as a function of pH was carried out choosing values at which adequate currents were obtained.. Then, selection of

The modiied colloidal platinum was supported on commercial silica and the catalytic activity was studied in two reactions: the hydrogenation of ethyl pyruvate and the hydrogenation

The presence of the O-DMSO molecule in the fac - [RuCl 2 (S-DMSO) 3 (O-DMSO)] complex and its absence in the amine type complex, when the complexes are in solution, can

With the purpose of activity enhancement of 1-substituted phenyl-3-(2-thioxo-1,3,4-oxadiazol- 5-yl) β -carbolines 1a-c, reported as potential antitumor agents in our previous

Amazingly, results obtained revealed that 4 h incubation (Figure 2A) of ibroblast cells in the presence of 0.15 and 0.25 mM terrein was enough to promote 80% of cell death, the
