Silver/nickel oxide (Ag/NiO) nanocomposites produced via a citrate sol-gel route as electrocatalyst for the Oxygen Evolution Reaction (OER) in alkaline medium
(Springer, 2018)A series of Ag/NiO nanocomposite electrocatalysts, with a general molecular formula of Ag x Ni1 − xO, was synthesised employing the citrate sol-gel route and tested for the oxygen evolution reaction (OER) in 0.1 M KOH ... -
Functionalization of PLGA nanoparticles with 1,3-β-glucan enhances the intracellular pharmacokinetics of rifampicin in macrophages
(Springer, 2018)Purpose Mycobacterium tuberculosis which causes tuberculosis, is primarily resident within macrophages. 1,3-β-glucan has been proposed as a ligand to target drug loaded nanoparticles (NPs) to macrophages. In this study ... -
Continuous machine learning for abnormality identification to aid condition-based maintenance in nuclear power plant
(Elsevier, 2018)A condition-based maintenance (CBM) regime in a nuclear plant will result in eliminating unnecessary maintenance cost without jeopardizing the safety of the plant. The foundation of a good CBM regime is an accurate and ... -
Biomarkers in tigerfish (Hydrocynus vittatus) as indicators of metal and organic pollution in ecologically sensitive subtropical rivers
(Elsevier, 2018)Studies have shown high levels of contamination of both metals and organochlorine pesticides (OCPs) in aquatic systems of the world renowned Kruger National Park, South Africa. With effects evident in top predators, ... -
Morphological and molecular characterisation of some Criconematidae (Nematoda, Tylenchida): Ogma decalineatus (Chitwood, 1957) Andrassy, 1979, Criconema silvum (van den Berg, 1984) Raski & Luc, 1985 and Neobakernema variable (Raski & Golden, 1966) from South Africa and the USA
(Russian Academy of Sciences, 2017)During recent nematological surveys Ogma decalineatus and Criconema silvum were found in South Africa and Neobakernema variabile was found in California, USA. These three species are morphologically and morphometrically ... -
Metabolomics reveals the depletion of intracellular metabolites in HepG2 cells after treatment with gold nanoparticles
(Taylor & Francis, 2018)Studies on the safety of gold nanoparticles (GNPs) are plentiful due to their successful application in drug delivery and treatment of diseases in trials. Cytotoxicity caused by GNPs has been studied on the physiological ... -
Distinct intrinsic functional brain network abnormalities in methamphetamine‐dependent patients with and without a history of psychosis
(Wiley, 2018)Chronic methamphetamine use is associated with executive functioning deficits that suggest dysfunctional cognitive control networks (CCNs) in the brain. Likewise, abnormal connectivity between intrinsic CCNs and default ... -
A retrospective analysis of nickel exposure data at a South African base metal refinery
(Taylor & Francis, 2018)This study aimed to analyze historical soluble nickel exposure data from a South African base metal refinery and to identify trends in the soluble nickel exposure from 1981 until 2014 in the electrowinning department. Exposure ... -
Analytical treatment of particle motion in circularly polarized slab-mode wave fields
(Cambridge Univ Press, 2018)Wave–particle interaction is a key process in particle diffusion in collisionless plasmas. We look into the interaction of single plasma waves with individual particles and discuss under which circumstances ... -
Toward a comprehensive, theoretical model of compassion fatigue: an integrative literature review
(Wiley, 2018)This study was an integrative literature review in relation to compassion fatigue models, appraising these models, and developing a comprehensive theoretical model of compassion fatigue. A systematic search on PubMed, ... -
Irrigation water quality and the threat it poses to crop production: evaluating the status of the Crocodile (West) and Marico catchments, South Africa
(Springer, 2018)Ensuring food security is becoming increasingly difficult due to limited freshwater resources. Low-quality irrigation water also poses a severe threat to crop yield and quality. The aim of this study was to evaluate the ... -
Leptin and its relation to autonomic activity, endothelial cell activation and blood pressure in a young black and white population: the African-PREDICT study
(Thieme, 2018)An increasing prevalence of obesity-related hypertension is observed in the youth and may have severe consequences for future cardiovascular disease development. Previous studies portrayed leptin as a potential factor ... -
Diversity of participant representation within the 66th Lindau Nobel Laureate Meeting
