Influence of bioremediation stimulators in soil on development of oat seedlings (Avena sativa) and their aminopeptidase activity / Wpływ pozostałości…

2015

Abstract The selection of bioremediation techniques is important for purification of contaminated soil for agricultural use. Studies on soil contaminated with petroleum substances have indicated that the applied method of remediation has a bigger impact on the development of oat seedlings than the level of contamination. A yeast inoculum appeared to be a technique which was the friendliest to vegetation of oat

Ziegler–Natta catalysts based on vanadium halides: a DFT study

2003

Abstract Ziegler–Natta ethylene insertion into the carbon–metal bond for a number of fragments containing vanadium on different oxidation states as well as the halogen ligands has been studied by means of DFT. It is shown that the complexation and insertion energies are strongly influenced by the charge on the transition metal atom and, to some extent, by the electronegativity of the halogen atom. Complexation energy varies in the range −129 to −159 kJ/mol for charged species and −64 to −77 kJ/mol for neutral ones. Insertion energy follows a similar pattern and ranges from −28 to −62 and −82 to −100 kJ/mol, respectively. The calculated values are compared with the experimental results and d…
