In this paper a novel ligand debip (2-(4-N,N-diethylbenzenamine)1H-imidazo[4,5-f] [1, 10]phenanthroline) and its Ru(II) polypyridyl complexes [Ru(L)2(debip)](2+), (L = phen (1), bpy (2) and dmb (3)) have been synthesized and characterized by spectroscopic techniques. The DNA binding studies for all these complexes were examined by absorption, emission, quenching studies, viscosity measurements and cyclic voltammetry. The light switching properties of complexes 1-3 have been evaluated.

Synthesis of gold nanobactericides (AuNBs) were achieved by treating 1mM chloroaurate with cell free supernatant of Aneurinibacillus migulanus. Formation of AuNBs was initially was monitored with change in colour to ruby red. Further confirmation was assessed with UV-visible spectra with maximum absorption occurring at 510nm.

To develop sentence lists in the Telugu language for the assessment of speech recognition threshold (SRT) in the presence of background noise through identification of the mean signal-to-noise ratio required to attain a 50% sentence recognition score (SRTn).
This study was conducted in three phases. The first phase involved the selection and recording of Telugu sentences.
