Electrochemical immunosensor based on polythionine/gold nanoparticles for the determination of Aflatoxin B1
(MDPI, 2008)An aflatoxin B1 (AFB1) electrochemical immunosensor was developed by the immobilisation of aflatoxin B1-bovine serum albumin (AFB1-BSA) conjugate on a polythionine (PTH)/gold nanoparticles (AuNP)-modified glassy carbon ... -
Electrochemical interrogation of g3-poly(propylene thiophenoimine) dendritic star polymer in phenanthrene sensing
(MDPI, 2015)A novel dendritic star-copolymer, generation 3 poly(propylene thiophenoimine) (G3PPT)-co-poly(3-hexylthiophene) (P3HT) star co-polymer on gold electrode (i.e., Au|G3PPT-co-P3HT) was used as a sensor system for the ... -
Electrochemical performance of zinc carbodiimides based porous nanocomposites as supercapacitors
(Elsevier, 2021)The low energy densities of supercapacitors are generally limited by the used anodes. To develop supercapacitors with high energy densities, metal–organic framework (TRD-ZIF-8) derived honeycomb-like porous zinc carbodiimide ... -

(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
(MDPI, 2021)Metal chalcogenides such as copper zinc tin sulfide (CZTS) have been intensively studied as potential photovoltaic cell materials, but their viability have been marred by crystal defects and low open circuit potential (Voc) ... -
Eleventh annual Julius Nyerere memorial lecture in 2014
(University of the Western Cape, 2015)The event included a live performance by Jana Natya Manch (The People’s Theatre Group), also known as Janam (Birth). Janam has created original plays for the past 40 years; they have performed more than 8000 times in over ... -
Eliciting student feedback for course development: the application of a qualitative course evaluation tool among business research students
(Taylor & Francis, 2018)Student evaluations of teaching and learning are playing an increasingly important role in the delivery of high-quality, student-centred education. Insights into student perceptions of their learning experience provide ... -
Eliminating micro-porous layer from gas diffusion electrode for use in high temperature polymer electrolyte membrane fuel cell
(Elsevier, 2017)In this work, we report a simple strategy to improve the performance of high temperature polymer electrolyte membrane fuel cell (HT-PEMFC) by eliminating the micro-porous layer (MPL) from its gas diffusion electrodes ... -
Eliminating mother to child HIV transmission in South Africa
(World Health Organization (WHO), 2013)PROBLEM: The World Health Organization has produced clear guidelines for the prevention of mother-to-child transmission (PMTCT) of the human immunodeficiency virus (HIV). However, ensuring that all PMTCT programme components ... -
Elite capture and state neglect: new evidence on South Africa’s land reform
(Taylor & Francis, 2017)The most recent incarnation of South Africa’s land reform is a model of state purchase of farms to be provided on leasehold, rather than transferring title. This briefing presents headline findings from our field research ... -
Elite Capture in Land Redistribution in South Africa
(PLAAS, 2019-12-03)The research on elite capture in land redistribution in South Africa was conceived against the background of a significant decline in systematic research on land reform outcomes. Data on land reform outcomes and more ... -
Elite capture in South Africa’s land redistribution: The convergence of policy bias, corrupt practices and class dynamics
(Taylor and Francis Group, 2023)Land reforms are an important mechanism for addressing inequalities in society. Whileaddressing South Africa’s racialised land inequalities remains crucial, new forms of classinequality are produced through land reform, ... -
Elite land grabbing in Namibian communal areas and its impact on subsistence farmers’ livelihoods
(PLAAS, University of the Western Cape, 2011)This brief examines some emerging trends and dynamics in changing power relations in rural Namibian communities due to emerging new elites and the threats to subsistence farmers’ access to communal land and ... -
