Abstract

The paper deals with the issue of assessing the research competence of the academic staff in higher educational institutions. The criteria for carrying out an objective analysis of the state of research competence formation of the academic staff are described. Indicators that reveal the main features of the above mentioned criteria and imply the possibility of assessment using appropriate techniques, questionnaires, tests, etc. are defined.

Abstract

© 2015 Elsevier Ltd. All rights reserved. New nitronyl nitroxides LMe and LMe-CP containing a 4-methylpyridin-3-yl substituent were synthesized. It was found that the interaction of Cu(hfac)2 with LMe and LMe-CP gave binuclear [Cu(hfac)2LMe]2 and [Cu(hfac)2LMe-CP]2·Solv (Solv = n-C6H14, n-C10H22, n-C16H34) and chain polymer {[[Cu(hfac)2]2LMe2][Cu(hfac)2]}∞ heterospin complexes. An important structural peculiarity of LMe and LMe-CP is a large dihedral angle between the planes of the O•-N-CN → O paramagnetic fragment and the pyridine ring: 55.2 and 56.1°, respectively. The presence of a methyl group in the pyridine ring of the nitroxide molecule in {[[Cu(hfac)2]2LMe2][Cu(hfac)2]}∞ proved favorable for spin transition at nearly room temperature.
