The Medal Of The Chemical Research Society Of India Awarded To Penn State Chemist Ayusman Sen
Ayusman Sen, Distinguished Professor of Chemistry at Penn State University, has been honored with the Chemical Research Society of India (CRSI) Medal. Sen is only the second recipient of the medal, which is awarded exclusively to outstanding chemists of Indian origin who work outside of India. Sen's research encompasses the twin themes of catalysis and new materials, with one of the goals being the development of new catalysts that will enable the synthesis of polymers and related materials with novel combinations of properties...

Synthesis, Characterization, and DNA-Binding Studies of Mononuclear Copper(II)-Phenanthroline-Tyrosine Complex.
Authors: Reddy PR, Manjula P
The mononuclear complex [Cu(II)(phen)(L-Tyr)(H(2)O)] was synthesized and structurally characterized by elemental analysis, magnetic susceptibility, UV/VIS, IR, and EPR spectroscopy, and ESI mass spectrometry. The electronic and EPR spectral data suggest a square-pyramidal geometry around Cu(II). Absorption spectra, thermal denaturation, and fluorescence-spectroscopic studies were conducted to assess the interaction of the Cu(II) complex with calf thymus DNA (CT DNA). The intrinsic binding constant for CT DNA/complex (K(b)=3750 M(-1)) and Stern-Volmer quenching constant (K=0.39) were determined.
