BIOINFORMATICS: ENRICHING THE MATERIAL SCIENCE Journal of Biological ,Pharmaceutical And Chemical ResearchJournal of Biological ,Pharmaceutical And Chemical Research2394-3076201524 M. K. Sharma1, R. N. Yadav1, S. K. Chakrabarti2 Page No. 1-4 1 Material science is an emerging field of science. It is an interdisciplinary science comprising of physics, chemistry, biology, earth science, computer science and technology as well as materials engineering. Due to the advancement of knowledge now-a-days each of these branches of science has different sub-branches. There are several interrelations among these branches and subbranches. Bioinformatics is such an emerging interdisciplinary science. In this paper we have discussed that day by day as the material science is gradually being enriched, bioinformatics has also an important role in it. Key words: Biophysics, Biochemistry, Computer science, DNA, Protein. http://www.jobpcr.com/archive-abs.php?arc=260http://www.jobpcr.com/archive/JOBPCR-2015-2-4-037-1-4.pdf

ENTROPY OF MIXING OF TWO LEAD BASED BINARY LIQUID ALLOYS: A STATISTICAL MECHANICAL STUDY Journal of Biological ,Pharmaceutical And Chemical ResearchJournal of Biological ,Pharmaceutical And Chemical Research2394-3076201524 N. K. Mishra Page No. 9-12 1 The thermodynamic properties of the lead based binary liquid alloys are often found to vary considerably from the ideal values. Here two such alloyslithium-lead and sodium-leadhave been considered. Efforts are made to compute their entropies of mixing at different concentrations of the constituent species by using Florys model. In this course the temperature dependence of the interchange energy has also been introduced. The results indicate that the size effect in the present alloys may not be an important factor for shaping the entropy of mixing as for other thermodynamic calculations. Key words: Florys model, Size effect, Interchange energy, Free energy of mixing, Heat of mixing. http://www.jobpcr.com/archive-abs.php?arc=262http://www.jobpcr.com/archive/JOBPCR-2015-2-4-039-9-12.pdf

ACTIVITY OF THE ALKALI METALS IN THEIR LEAD BASED BINARY LIQUID ALLOYS Journal of Biological ,Pharmaceutical And Chemical ResearchJournal of Biological ,Pharmaceutical And Chemical Research2394-3076201524 P. K. Karn Page No. 13-17 1 Alkali metals are highly reactive. Within a binary alloy they generally form complexes. Due to formation of such complexes the thermodynamic properties of the alloys often show asymmetry around equi-atomic composition. In the present work we have considered two lead based binary alloys of alkali metals e.g. Li-Pb and Na-Pb. The phase diagrams of these alloys reveal that at their liquid state complexes are formed. We have confined our study in computing the activity of lithium and sodium within these molten alloys. Activity is one of the fortunate thermodynamic functions which can be measured directly by experiment. For the purpose of our theoretical study Florys model has been employed. It is a statistical mechanical model based on the size factor of the constituent species of a binary liquid alloy. For each alloy we have started with the mathematical expression for the free energy of mixing according to this model and found out the interchange energy between the ingredients from the observed values of the former by the method of successive approximations. Using this value of the interchange energy finally the activity of the concerned alkali metal has been computed for different concentrations. Our calculation indicates that the lithium-lead liquid alloys are structurally disordered at lower concentrations of lithium. Key words: Binary liquid alloys, Alkali metals, Lead based alloys, Florys model, Free energy of mixing, Interchange energy, Activity. http://www.jobpcr.com/archive-abs.php?arc=263http://www.jobpcr.com/archive/JOBPCR-2015-2-4-040-13-17.pdf

MATHEMATICAL STUDY OF THE THERMODYNAMICS OF Cd-Na LIQUID ALLOY Journal of Biological ,Pharmaceutical And Chemical ResearchJournal of Biological ,Pharmaceutical And Chemical Research2394-3076201524 R. R. Thapa Page No. 18-21 1 The concentration dependent thermodynamic properties of cadmium-sodium liquid alloy are interesting in many ways. The free energy of mixing, entropy of mixing and heat of mixing are quite asymmetric about the equi-atomic composition. The phase diagram of Cd-Na alloy shows a wavy liquidus line with a small hump around the stoichiometric composition. The quasi-lattice chemical model is used for computation of its thermodynamic entities. The results explain the observed asymmetry in the properties of mixing of Cd-Na liquid alloy around equi-atomic composition. Key words: Binary alloy, Equi-atomic composition, Quasi-lattice model, Ordering energy, Free energy of mixing, Entropy of mixing, Heat of mixing. http://www.jobpcr.com/archive-abs.php?arc=264http://www.jobpcr.com/archive/JOBPCR-2015-2-4-041-18-21.pdf
