Thus viability and analysis of input and output of energy is of prime concern before any process or reaction or for that matter if any engine or industry is being set up because after all it is the process or reaction which takes place inside the engine. As the globe is gradually but certainly moving away from fossil fuel or carbon-based energy production as it immensely pollutes the environment due to evolution of greenhouse gases into the environment and contribute towards global warming, it is but necessary to evaluate the impact assessment of the pollutants on the environment before any engine or industry is being developed or installed. It is in this perspective that the thermochemical studies of metal compounds of ‘s’ ‘p’ ‘d’ and ‘f’ block elements and those of organometallic compounds become extremely important as it clearly identifies and defines the products as well as absorption and evolution of energy involved therein. 2016-01-15T00:00:00Z http://pucir.inflibnet.ac.in:8080/jspui/handle/123456789/944 Title: Arsenic Attenuation through Phytochemistry Authors: Pathak, Raghvendu Abstract: Inorganic pollutants, which when present in higher concentrations than the permissible or prescribed limits, contaminate both soil and aquatic bodies and affect human health and environment very badly. Focusing on the damages caused by inorganic forms of Arsenic (As) chemicals to health and environment, the paper presents an overview of the investigation of As remediation through photochemistry. 2016-01-01T00:00:00Z http://pucir.inflibnet.ac.in:8080/jspui/handle/123456789/943 Title: Calorimetric Computation of Enthalpy of Formation of Trisacetylacetonato Chromium(III) [Cr(C5H7O2)3(c)] Authors: Pathak, Raghvendu Abstract: From thermochemical studies of organometallic compounds, a host of thermodynamic parameters viz., heat capacity, entropy, Gibbs energy etc., can be evaluated. The present communication deals with the evaluation of enthalpy of combustion and thereby estimation of enthalpy of formation of crystalline trisacetylacetonato chromium(III) [Cr (C5H7O2)3 (c)] or [Cr (acac)3 cH) and enthalpy of formation fH° –1 –1 respectively. Experimental data obtained are in good agreement with one another. 2019-01-01T00:00:00Z http://pucir.inflibnet.ac.in:8080/jspui/handle/123456789/942 Title: The long-wavelength-limit of structure factor and chemical ordering in binary Ag-In melts Authors: Pathak, Raghvendu Abstract: The long-wavelength-limit partial structure factors, Sxy(0), have been determined for liquid silverindium (Ag-In) alloys using square well potential as perturbation over Percus-Yevick (PY) hard sphere reference system. Obtained Sxy(0) at various compositions of In have been employed to calculate isothermal compressibility and chemical ordering in the alloys. Further, homocoordination and hetero-coordination in Ag-In alloys have been studied at microscopic level in terms of mutual and intrinsic diffusion coefficients 2015-01-29T00:00:00Z
