(MDPI, 2020)his study investigates the most effective electrocatalyst for glycerol oxidation reaction (GOR) in alkaline medium for five synthesized electrocatalysts, Pd, PdNi, PdNiO, PdMn3O4 and PdMn3O4NiO, supported on multi-walled ... -
An electrochemically active green synthesized polycrystalline NiO/MgO catalyst: Use in photo-catalytic applications
(Elsevier, 2018)For many years, research scientists have aided communities in their tremendous efforts towards environmental remediation. Due to their high physical and chemical stability, metal oxide nanoparticles (NPs) have been used as ... -
Electrochemically reduced graphene oxide pencil-graphite in situ plated bismuth-film electrode for the determination of trace metals by anodic stripping voltammetry
(ESG, 2014)An electrochemical platform was developed based on a pencil-graphite electrode (PGE) modified with electrochemically reduced graphene oxide (ERGO) sheets and in conjunction with an in situ plated bismuth-film (ERGO-PG-BiE). ... -
Electrochemiluminescence at 3D Printed Titanium Electrodes
(Frontiers Media SA, 2021)The fabrication and electrochemical properties of a 3D printed titanium electrode array are described. The array comprises 25 round cylinders (0.015 cm radius, 0.3 cm high) that are evenly separated on a 0.48 × 0.48 cm ... -
Electrodeposited CuO thin film for wide linear range photoelectrochemical glucose sensing
(Elsevier, 2022)Cupric oxide (CuO) has been used as a non-enzymatic glucose sensor for decades. However, there is a paucity of publications on bare CuO based photo electrochemical (PEC) glucose detection. In this study, a photo active ... -
Electronic health record (ehr) adoption in South African healthcare centres: a case of NW province
(University of the Western Cape, 2019)Electronic Health Records (EHRs) enable the healthcare sector to enjoy increased efficiency and throughput, whilst cutting overhead costs in healthcare centres. The aim of this study was to investigate the adoption of ... -
Electronics of anion hot injection-synthesized te-functionalized kesterite nanomaterial
