Hydrides of Laves type Ti–Zr alloys with enhanced H storage capacity as advanced metal hydride battery anodes
(Elsevier, 2020)The present work was focused on the studies of the effect of variation of stoichiometric composition of Ti–Zr based AB2±x Laves phase alloys by changing the ratio between A (Ti + Zr) and B (Mn + V + Fe + Ni) components ... -
Hydrocarbon generation and migration from Barremian – Aptian source rocks, Northern Orange Basin, offshore Western South Africa: A 3d numerical modelling study
(Wiley-Blackwell, 2021)A 3D numerical modelling workflow was applied to the Barremian—Aptian source rock interval in a shelfal to lower slope area of the northern Orange Basin, offshore western South Africa. The main objective was to investigate ... -
Hydrogen absorption study of high-energy reactive ball milled Mg composites with palladium additives
(Elsevier, 2013)Hydrogenation behaviour, structure, morphology and dehydrogenation/re-hydrogenation performances of Mg–Pd nanocomposites prepared by high-energy reactive ball milling in H2 (HRBM) of Mg in the presence of amorphous and ... -
Hydrogen storage behavior of magnesium catalyzed by nickel-graphene nanocomposites
(ScienceDirect, 2019)In present study nanocomposites of Graphene Like Material (GLM) and nickel containing 5–60 wt % Ni were prepared by a co-reduction of graphite oxide and Ni2+ ions. These nanocomposites served as effective catalysts of ... -
Hydrogeochemical characteristics and evaluation of groundwater quality for domestic and irrigation purposes: A case study of the Heuningnes Catchment, Western Cape Province, South Africa
(Springer, 2020)Knowing the quality of water is imperative if the water is meant for drinking or agricultural purposes. The spatial and temporal groundwater quality in the Heuningnes Catchment was investigated, and its appropriateness ... -
A hydrogeomorphological approach to quantification of groundwater discharge to streams in South Africa
(Water Research Commission, 2002)In South Africa, the flow requirements for maintaining the normal functioning of aquatic ecosystems is termed the “ecological reserve”, and these should be determined when a licence application for water allocation is ... -
Hydrological modelling and climate adaptation under changing climate: A review with a focus in sub-Saharan Africa
(MDPI, 2022)Empirical evidence continues to show that climate change remains a threat to the stability of the hydrologic system. As the climate system interacts with the hydrologic cycle, one significant repercussion of global warming ... -
Hydromedusae off the Orange River Mouth, Southern Africa
(NISC (Pty) Ltd and Taylor& Francis, 2003)A total of 242 zooplankton samples from the upper 100 m of the water column was collected discontinuously from March 1997 to January 1999 off the Orange River mouth on the west coast of southern Africa. Six species of ... -
Hypertension in African populations: Review and computational insights
(MPDI, 2021)Hypertension (HTN) is a persistent public health problem affecting approximately 1.3 billion individuals globally. Treatment-resistant hypertension (TRH) is defined as high blood pressure (BP) in a hypertensive patient ... -
Hyphenated LC-ICP-MS/ESI-MS identification of halogenated metabolites in South African marine ascidian extracts
(The South African Chemical Institute, 2018)Extracts of 13 species of marine ascidian collected in Algoa Bay were analyzed by LC-ICP-MS/ESI-MS. This technique allows parallel analysis of the molecular species and the presence of certain elements. The LC-ICP-MS/ESI-MS ... -
Hypoglycaemic activity of biosynthesized copper oxide nanoparticles in alloxan-induced diabetic Wister rats
(Wiley, 2023)Diabetes mellitus (DM) is a metabolic disorder that affects the body's ability to produce or use insulin. This study evaluated the hypoglycaemic activity of biosynthesized copper oxide nanoparticles (CuO-NPs) ... -
Hypolithic and soil microbial community assembly along an aridity gradient in the Namib Desert
(Springer, 2013)The Namib Dessert is considered the oldest desert in the world and hyperarid for the last 5 million years. However, the environmental buffering provided by quartz and other translucent rocks supports extensive hypolithic ... -
