The University of Hyderabad is a Central University located in the city of Hyderabad in Telangana, India. Founded in 1974, this public and largely residential university occupies about 2000 acres in the locality of Gachibowli on the outskirts of the city. The University came into existence as one of the points of the so-called Six-Point Formula of 1973, the political settlement arrived at after the protests during the 1960s and early 1970s in the region. The organic chemist and Professor of Chemistry at the Banaras Hindu University, Gurbakhsh Singh was the first Vice-Chancellor of the UoH, from 1974 to 1979. Shri B D Jatti was the first Chancellor of the University. The Governor of the state of Telangana is ex-officio the Chief Rector of the University, while the President of India is the Visitor to the University.In January 2015 University of Hyderabad has been selected for the Visitor’s Award for the Best Central University in India Wikipedia.

Nano/micro scale passive organic optical waveguides, which are self-assembled from tailor made organic molecules, are one of the less studied branches of organic photonics. This perspective article is primarily focused on the research work related to one dimensional (1D) passive organic optical waveguides. In the beginning, a brief theory of organic waveguides, recent works on active organic waveguides and attempts towards fabrication of integrated photonic components and circuits will be discussed. Later more focus will be given to passive organic wave guiding materials derived from 1D hexagonal submicrotubes, parallelepipedic nanotubes, shape shifting organic structures and paramagnetic tubes. By using laser ablation techniques, the polishing of organic tube tips, the precise control of the light propagation distance and the creation of multiple optical outputs will be discussed. This perspective also highlights some noteworthy applications of passive organic waveguides in remote sensing, excitation and defect identification. The end of this article concludes with the potential of passive organic optical waveguides in future organic nanophotonics. This journal is © the Partner Organisations 2014. Source

To understand the mechanism of ionic detergent-induced protein denaturation, this study examines the action of sodium dodecyl sulfate on ferrocytochrome c conformation under neutral and strongly alkaline conditions. Equilibrium and stopped-flow kinetic results consistently suggest that tertiary structure unfolding in the submicellar and chain expansion in the micellar range of SDS concentrations are the two major and discrete events in the perturbation of protein structure. The nature of interaction between the detergent and the protein is predominantly hydrophobic in the submicellar and exclusively hydrophobic at micellar levels of SDS concentration. The observation that SDS also interacts with a highly denatured and negatively charged form of ferrocytochrome c suggests that the interaction is independent of structure, conformation, and ionization state of the protein. The expansion of the protein chain at micellar concentration of SDS is driven by coulombic repulsion between the protein-bound micelles, and the micelles and anionic amino acid side chains. © 2009 Wiley Periodicals, Inc.

In this work, 110 energetic salts were designed and studied for their applications in energetic materials. Density functional theory methods were used to predict the heats of formation (HOFs), electronic structure, and energetic properties of a series of triazine-based ionic and nonionic compounds. It is observed that the -N3 group, triazole, tetrazole, triazine, and tetrazine are effective structural units for increasing the HOFs in the designed compounds. The HOFs of cations and anions and the lattice energies of the salts were calculated separately to obtain the HOFs of the salts based on the Born-Haber cycle. The combination of three cations within the same framework is very useful for improving the HOFs of energetic salts. Similarly, the presence of the -NO2 and -NHNO2 groups in the same structure were found to be helpful in improving densities through strong inter- and intramolecular hydrogen bonding. The detonation velocities and detonation pressures of the salts were predicted by the Kamlet-Jacobs equations using calculated densities and HOFs. The calculated energetic properties indicate that the combination of suitable anion and cation species is useful for modifying detonation properties and oxygen balances (OB). The predicted results reveal that most of the compounds outperform hexahydro-1,3,5-trinitro-1,3,5-triazine and 2,4,6-trinitro-1,3,5-triaminobenzene and may be considered as potential candidates for high-energy materials. These results provide basic information for molecular design of novel high- energy salts. © 2013 American Chemical Society. Source

Chiral N-salicyl-β-amino alcohol Schiff bases are important ligands widely employed in asymmetric catalysis. These are referred to as 'tridentate salen ligands' and are considered as a member of the well-known 'privileged ligands' group. The desire to understand the roles of weak non-covalent interactions in catalysis has greatly expanded the scope of structural studies on catalytic complexes. This review focuses on the structural and supramolecular features of the metal complexes derived from chiral N-salicyl-β-amino alcohol Schiff base ligands. Metal complexes of varying nuclearities, such as, mono-, di-, tri- and tetra-nuclear complexes, have been reported from this group of ligands. The geometries of the metal centers present in these complexes vary from tetrahedral, square-planar, square-pyramidal, octahedral to trigonal prismatic. The available structural data clearly indicate the coordination versatility of this group of ligands towards various metal ions. In addition, these complexes exhibit a variety of weak bonding interactions leading to the formation of supramolecular structures such as helices, 1-D chains, 3-D networks, etc. in solid state. The articles discussed here highlight the competence of chiral N-salicyl-β-amino alcohol Schiff base ligands to support various structural and supramolecular features in their complexes, but the role of these features in determining their catalytic efficiencies have not yet been studied in detail. We believe that the present review may inspire many such studies in future. © 2013 Elsevier B.V. Source
