Journal ArticleDOI
Hydrogen-Bonded Pyridine-Water Complexes Studied by Density Functional Theory and Raman Spectroscopy
TL;DR: In this article, a density functional theory (DFT) at the B3LYP/6-31++G(d,p) level was employed to obtain the optimized geometries and vibrational spectra of several pyridine(Py)−water(W) complexes with stoichiometric ratios ranging from 2:1 (Py2W) to 1:3 (PyW3).
Journal ArticleDOI
Investigations on structural and optical properties of ZnO and ZnO:Co nanoparticles under dense electronic excitations
TL;DR: In this paper, the structural, morphological, and optical properties of Co-doped ZnO nanoparticles (NPs) prepared by a sol-gel method before and after dense electronic excitations caused by swift heavy ion irradiation have been reported.

TL;DR: The results indicate that aqueous solubility and stability of Curcumin can be achieved by preparing its quantum dots and demonstrates that by sizing down the particle size has not only enhanced its antimicrobial properties but it has also shown its antibiofilm activities.
Journal ArticleDOI
Liquid crystal based sensor system for the real time detection of mercuric ions in water using amphiphilic dithiocarbamate
Sachin Kumar Singh,Rajib Nandi,Kirtika Mishra,Hemant Kumar Singh,Ranjan K. Singh,Bachcha Singh +5 more
TL;DR: In this article, the authors developed a simple, sensitive, label-free and real time detection method for mercuric ions (Hg2+) in water using liquid crystals (LCs).
Journal ArticleDOI
Hydrogen-bonding between pyrimidine and water: a vibrational spectroscopic analysis.
TL;DR: In this article, an experimental and theoretical study on hydrogen-bonding between pyrimidine and water as the H-donor was performed by using polarization-resolved linear Raman spectroscopy with the pyridine ring breathing mode ν1 as a marker band.
