Bio-synthesis of silver nanoparticles using agroforestry residue and their catalytic degradation for sustainable waste management

Author: Anand, K ; Kaviyarasu, K ; Muniyasamy, Sudhakar ; Roopan, SM ; Gengan, RM ; Chuturgoon, AA Date: Jul 2017 The sustainable synthesis of nanoparticles provides an eco-friendly and interesting approach in the domain of clean synthesis and nanobiotechnology. The in vitro synthesis of silver nanoparticles from the aqueous extract of an indigenous South ... Read more
A DFT study of disperse yellow 119 degradation mechanism by hydroxyl radical attack

Author: Wahab, OO ; Olasunkanmi, LO ; Govender, Krishna ; Govender, PP Date: Dec 2018 Previous experimental studies had proposed two possible mechanisms, that is, N-N or C-N bond cleavage, for azo dye degradation. However, the relative feasibility of these mechanisms based on their energetics has not been properly explored. ... Read more
DMol3/COSMO-RS prediction of aqueous solubility and reactivity of selected Azo dyes: Effect of global orbital cut-off and COSMO segment variation

Author: Wahab, OO ; Olasunkanmi, LO ; Govender, Krishna ; Govender, PP Date: Jan 2018 Aqueous solubility and reactivity of four azo dyes were investigated by DMol3/COSMO-RS calculation to examine the effects of global orbital cut-off and COSMO segment variation on the accuracies of theoretical solubility and reactivity. The ... Read more
Prediction of aqueous solubility by treatment of COSMO-RS data with empirical solubility equations: The roles of global orbital cut-off and COSMO solvent radius

Author: Wahab, OO ; Olasunkanmi, LO ; Govender, Krishna ; Govender, PP Date: Jun 2019 Aqueous solubility values of (E)-2-(ethyl(4-((4-nitrophenyl)diazenyl)phenol)amino)ethanol [B1], (E)-2,2'-((4-((4-nitrophenyl)diazenyl)phenyl)azanediyl)diethanol [B2], (E)-2,2'-((3-methyl-4-((4-nitrophenyl)diazenyl)phenyl)azanediyl)diethanol ...
