The impact of educational reform and categorization of scientific journals and scientists on physics in Serbia

The trend of the increasing participation and importance of female physicists in Serbia continues. Many women have taken leading position in research and faculty governance and are contributing significantly to educational reform and the improvement of physics education in the primary and secondary schools

Trends in the Presence and Roles of Women Physicists in Serbia

In general, the portion of women in physics has been increasing in recent years in Serbia, as well as their presence in research and academic institutions. The percentage of women who earned BSc degrees in physics is greater than men. In this respect the situation in Serbia is different from most other countries. But more men than women earned MSc and PhD degrees

A molecular inclusion complex of atenolol with 2-hydroxypropyl-b-cyclodextrin; the production and characterization thereof

The molecular inclusion complex of atenolol with 2-hydroxypropyl-b-cy­clodextrin was synthesized using the coprecipitation method. The complex obtained was characterized by FT-IR, 1H‑NMR, 13C-NMR spectroscopy, as well as by DSC and X-ray diffraction analysis. The DSC analysis confirmed the existence of the com­plex with the endothermic atenolol melting peak at about 155 ºC disappearing. The X-ray diffraction patterns of the complex and 2-hydroxypropyl-b-cyclodextrin were very similar, thus confirming the complete inclusion of the atenolol molecule within the cavity of the 2-hydroxypropyl-b-cyclodextrin. The peaks originating from ate­nolol were completely absent in the diffractogram of the complex. 1H-NMR and 13C-NMR spectra showed certain changes in the chemical shifts of protons and C atoms from atenolol and 2-hydroxypropyl-b-cyclodextrin, indicating that a complex had been formed and also which protons participated in the hydrogen bonds which formed the complex. The atenolol solubility in water was improved (254 mg com­plex cm-3, i.e., 37.5 mg atenolol cm-3), and in pH 3 HCl solution (251 mg com­plex cm-3, i.e., 37 mg atenolol cm-3) when compared to pure atenolol, and even when compared to the atenolol complex with b-cyclodextrin. The increased solubility en­sures greater bioavailability of the active component and, due to the low solubility, significantly corrects for the lack of the basic active substance and, simultaneously, increases its overall therapeutic effect, combined with reduced side effects

The influence of water molecule coordination onto the water-aromatic interaction. Strong interactions of water coordinating to a metal ion

The interactions between water molecules (non-coordinating and coordinating) and aromatic rings were studied by analyzing data in the Cambridge Structural Database and by quantum chemical calculations. The results show the influence of water coordination to a metal ion; interactions of coordinating water are stronger. The MP2/def2-QZVP interaction energies of non-coordinating water and neutral aqua complexes [ScCl3(H2O)(3)], [ZnCl2(H2O)(4)], [CdCl2(H2O)(4)], and [ZnCl2(H2O)(2)] with benzene molecule are -3.36, -5.10, -5.43, -6.86, and -5.14 kcal mol(-1), respectively. Interactions of charged aqua complexes [ZnCl(H2O)(5)](+) and [Zn(H2O)(6)](2+) are stronger, -9.69 and -13.96 kcal mol(-1), respectively. The calculations also reveal strong long-range interactions: at the distance of 3.0 angstrom the interaction energies of neutral complexes are in the range of -4.11 to -4.91 kcal mol(-1), while interaction energies of charged complexes are -6.37 and -10.76 kcal mol(-1).Supplementary material: [http://cherry.chem.bg.ac.rs/handle/123456789/3555

Classification of stacking interaction geometries of terpyridyl square-planar complexes in crystal structures

Stacking interactions of terpyridyl square-planar complexes in crystal structures were studied analyzing data from the Cambridge Structural Database. In most of the crystal structures, two terpyridyl complexes were oriented "head-to-tail" or "head-to-head", with "head-to-tail orientation" being most prevalent. The number of structures with other orientations was very small. Based on the analysis of interacting geometries, we classified overlaps of terpyridyl complexes into six types. The types were defined by values of several geometrical parameters and all interactions of the same type had very similar overlap patterns
