NAPHTHOL BINARY DRUG SYSTEM 2018-10-19T22:14:13+00:00 H. Shekhar hshe2503@rediffmail.com Manoj Kumar manojcbpstk@gmail.com <p>With view to synthesize and characterize the enhanced pharmaceutical properties of the solid-liquid dispersions of binary drug system through green chemical technique the present communication have been undertaken for detailed investigation of thermodynamic and interfacial properties of benzimidazole (BI) and β. naphthol (βN) binary eutectic and non-eutectic drug dispersions. Eutectic solid dispersion was observed at 0.657 mole fraction of β. naphthol (βN) and at melting temperature 90°C.</p> <p>Thermodynamic quantities; Partial and Integral &nbsp;excess Gibbs energy (g<sup>E</sup>), excess enthalpy (h<sup>E</sup>), excess entropy (s<sup>E</sup>) of eutectic and non-eutectic dispersions were determined with the help of activity coefficient data. The negative deviation from ideal behaviorhas been seen in the system which refers stronger association between unlike molecules during formation of binary mix. The negative value of Gibbs free energy of mixing (DG<sup>M</sup>) refers the mixing for all eutectic and non-eutectic dispersions is spontaneous. The solid-liquid interfacial characteristics i.e., entropy of fusion per unit volume (DS<sub>V</sub>), solid-liquid interfacial energy (s), roughness parameter (α), grain boundary energy and roughness parameter (α) of eutectic and non-eutectic solid dispersions have been reported.</p> <p>The size of critical nucleus at different undercoolings has been found in nanoscale, which may be a big significance in pharmaceutical world. The value of roughness parameter, α &gt; 2 was observed which manifests the faceted and irregular growth leads in the system.</p> 2018-09-29T00:00:00+00:00 ##submission.copyrightStatement## http://giapjournals.com/index.php/gctl/article/view/gctl.2018.422 APPLICATIONS OF GREEN CHEMISTRY PRINCIPLES IN AGRICULTURE 2018-10-19T22:14:13+00:00 SUNEETA BHANDARI sunitabhandari77@gmail.com <p>Green chemistry involves the design and development of products and processes that minimize or eliminate the use and generation of chemicals hazardous to the environment and human health. The principles of green chemistry involve the development of green catalysts and use of non-toxic reagents. Green chemistry emphasizes the use of reactions improved atom efficiency, use of solvent-free or environmentally benign recyclable solvent system and the use of renewable resources.</p> <p>Nowadays, green chemistry plays a new paradigm in the field of agriculture. Sustainable agriculture and green chemistry are both revolutionary fields and intertwined. In the last few years, for sustainable production in agriculture use of renewable biomass resources increases to generate bio-based food products with low inputs, zero waste, substantial social values and minimizing environmental impact. This article provides a good insight into green chemistry principles in sustainable agriculture.</p> 2018-09-29T00:00:00+00:00 ##submission.copyrightStatement##
