Activation of dioxygen molecules on dinuclear metal centersProceedings / Indian Academy of Sciences - Tập 111 - Trang 413-424 - 1999
Yoshihiko Moro-Oka
Activation of dioxygen molecules on transition metal centers, especially dinuclear metal centers was systematically investigated using hydrotris(3,5-dialkylpyrazolyl)borate ligands from both organometallic and bioinorganic viewpoints. Physicochemical data and X-ray crystallography of synthesized dicopper-O2 complexes revealed aμ-η

Polystyrene supportedt-butyl chromates: Effect of the degree of crosslinking on reactivityProceedings / Indian Academy of Sciences - Tập 110 - Trang 499-506 - 1998
K Geethakumari, K Sreekumar
Polystyrene supportedt-butyl chromate reagents were prepared using divinylbenzene as the crosslinking agent. The extent of crosslinking was varied from 2 to 20% (2, 5, 10, 15 and 20%). These polystyrene systems appeared to be amenable to structural variations for studying the effect of the nature and extent of crosslinking on the reactivity of the attached functional groups. Polystyrene supportedt...... hiện toàn bộ
Effect of the valine-threonine constraint on the dynamics of the proline helix — A molecular dynamics studyProceedings / Indian Academy of Sciences - - 1994
S. Shobana, Gautham Nadig, Saraswathi Vishveshwara
Proline residues in helices play an important role in the structure of proteins. The proline residue introduces a kink in the helix which varies from about 5° to 50°. The presence of other residues such as threonine or valine near the proline region can influence the flexibility exhibited by the kinked helix, which can have an important biological role. In the present paper, the constraint introdu...... hiện toàn bộ
Sum rules in inelastic gas-surface scatteringProceedings / Indian Academy of Sciences - Tập 96 - Trang 249-252 - 1986

An explanation for sum-rules observed in gas-surface scattering is offered via a classical scaling theory for inelastic collisions.
Structure-function relationship in some macrocyclic dicopper complexesProceedings / Indian Academy of Sciences - Tập 102 - Trang 269-282 - 1990
K. Nag
A number of macrocyclic dicopper(II) complexes containing aza-, amino or amido nitrogen and phenolic oxygen donors are described, X-ray crystal structures of several of these compounds are discussed. An account of their electrochemical behaviour and magnetic properties is given. Factors that affect electron transfer behaviour with regard to stabilization of the lso- and mixed-valence species, intr...... hiện toàn bộ
