A highly resourceful magnetically separablemagnetic nanoparticles from aqueous peel extract of Bottle gourds for organic dyes degradation
(Elsevier, 2017)Present work, described the green synthesis of Pd supported Fe3O4 magnetic nanoparticles BG/Pd/Fe3O4MNPs from aqueous Peel extract of Bottlegourds (BG) which act as reducing and capping agent. Synthesized nanoparticles of ... -
The effect of acid demineralising bituminous coals and de-ashing the respective chars on nitrogen functional forms
(Elsevier, 2017)An opportunity presented itself to compare changes in nitrogen functional forms brought by the acid treatment of South African bituminous coals and their respective chars. X-ray photoelectron spectroscopy (XPS) was used ... -
The experimental evaluation of nitrogen transformation in South African coal chars and the concomitant release of nitrogenous species
(North-West University, 2018)The effect of typical South African (SA) coal properties on nitrogen functional transformation and release were examined in the course of pyrolysis in a fluidised bed (FB) and drop-tube furnace (DTF). Chars were generated ... -
FTIR and XPS study of the adsorption of probe molecule used to model alkyd resin adhesion to low carbon aluminum killed steel
(Elsevier, 2009)An important factor in achieving maximum adhesion of a particular coating system to the substrate lies in the proper pre-treatment of the substrate prior to the application of the coating. The Lewis acid–base properties ... -
Green arbitrated synthesis of Fe3O4 magnetic nanoparticles with nanorod structure from pomegranate leaves and Congo red dye degradation studies for water treatment
(Elsevier, 2017)An efficient, cost effective and eco-friendly approach has been developed for the synthesis of Fe3O4 magnetic nanorods (MNRs) using aqueous extract of Pomegranate leaves (PG). The synthesized PG-Fe3O4 MNRs were characterized ... -
Towards practical applications of EQCN experiments to study Pt anchor sites on carbon surfaces
(Springer, 2018)This work investigates the viability and outlines the current challenges in electrochemical quartz crystal nanobalance (EQCN) experiments on supported Pt catalysts. EQCN experiments involving Pt supported on 2-D “surface-treated ... -
Transformation of nitrogen functional forms and the accompanying chemical-structural properties emanating from pyrolysis of bituminous coals
(Elsevier, 2018)Characterisation of simultaneous changes in nitrogen functionalities and condensed aromatic crystallites during pyrolysis of bituminous coals was conducted. X-ray photoelectron spectroscopy (XPS) was utilised to determine ...
