Molecular interactions and structures in ethylene glycol-ethanol and ethylene glycol-water solutions at 303 K on densities, viscosities, and refractive indices data

Abstract: Molecular interactions and structural fittings in binary ethylene glycol + ethanol (EGE, x EG = 0.4111–0.0418) and ethylene glycol + water (EGW, x EG = 0.1771–0.0133) mixtures were studied through the measurement of densities (ρ), viscosities (η), and refractive indices (n D ) at 303.15 K. Excess viscosities (η E ), molar volumes (V m ), excess molar volumes (V ), and molar retractions (R M ) of the both binary systems were computed from measured properties. The measured and computed properties have been used to understand the molecular interactions in unlike solvents and structural fittings in these binary mixtures.

Metalloporphyrins as Oxidation Catalysts: Moving Toward “Greener” Chemistry in the Inorganic Chemistry Laboratory

Abstract: Training future chemists to be aware of the environmental impact of their work is of fundamental importance to global society. To convince chemists to embrace sustainability, the integration of green chemistry across the entire chemistry curriculum is a necessary step. This experiment expands the reach of green chemistry techniques into the inorganic laboratory curriculum. Students utilize a metalloporphyrin catalyst with hydrogen peroxide to facilitate the production of cyclooctene oxide eliminating the need for the environmentally harmful iodosylbenzene catalyst. Both chloroiron(III) tetraphenylporphyrin and chloroiron(III) tetra(pentafluorophenyl)porphyrin are incorporated into the experiment to allow comparison of catalytic activity. Product characterization includes UV-visible spectroscopy and gas chromatography-mass spectrometry.

Research Training, Institutional Support, and Self-Efficacy: Their Impact on Research Activity of Social Workers

Abstract: While the expectations for social work practitioners to do research have increased, their involvement is still limited. We know little about what factors influence involvement in research. The present study proposes a theoretical model that hypothesizes research training and institutional support for research as the exogenous variables, research self-efficacy as an intervening variable, and research activity as the endogenous variable. The study tests the model using data collected from a random sample of social workers. To a large degree the data support the model. Research self-efficacy has a significant effect on research activity. It is also an important mediating variable for the effect of institutional support on research activity. Although institutional support for research has no direct effect, it has an indirect effect via self-efficacy on research activity. However, research training has no effect on research activity and self-efficacy in research. The implications of these findings are discussed.
