Equilibrium, thermodynamic, and kinetic modeling studies for the adsorptive removal of oxyanions from water
(TAYLOR & FRANCIS INC, DEC 2021)Water is being contaminated by different oxyanions which have many negative effects on the human body. This study deals with the adsorptive removal of Cr2O7-2, AsO4-3, and ClO4-1 oxyanions from water using diethanolamino ... -
Pd-PEPPSI: X-ray Structure, Spectroscopic Analyses, and Quantum Mechanical Studies
(2021)Pyridine enhanced precatalyst preparation stabilization and initiation (PEPPSI) complexes contain two halides, an unstable pyridine derivative and a bulky N-heterocyclic carbene (NHC) ligand. In this study, a new ... -
Activity analysis of new N-heterocyclic carbenes and silver N-heterocyclic carbene molecules against novel coronavirus by UV-vis, fluorescence spectroscopy and molecular docking
(2021)The biggest pandemic that this generation has experienced is still continuing. While researchers concentrated on vaccine studies, development of treatment procedures and anti-viral drugs are other important parts of ... -
Synthesis, characterization, antimicrobial and antibiofilm activity, and molecular docking analysis of NHC precursors and their Ag-NHC complexes
(2021)Microorganisms attach to surfaces and interfaces and form biofilms which create a sheltered area for host cell response. Therefore, biofilms provide troubles in fields such as medicine, food, and pharmaceuticals. Inhibition ... -
Theoretical computation of normalised radii, density and global hardness as a function of orbital exponent
(Springer International Publishing, 21 Februar)The recent work has an aim to establish a pivotal role of orbital exponent in the normalized atomic radii, atomic density and atomic hardness. These three periodic descriptors help to understand the real scenario of an ... -
A gossypol derivative as an efficient corrosion inhibitor for St2 steel in 1 M HCl + 1 M KCl: An experimental and theoretical investigation
(Journal of Molecular Liquids, 26 January)Currently, there are several types of corrosion inhibitors were studied. The new type of corrosion inhibitor based on a gossypol derivative was first introduced. The anti-corrosion performance of 6-aminopenicillanic acid ... -
