-
(2022)The vast majority of typical cathode materials for lithium ion batteries suffers from severe specific capacity due to structural changes that occur during the process of cycling, which may lead to fractures within the ...
-
(2023)Using “gravimetric analysis, potentiodynamic polarisation (PDP), and electrochemical impedance spectroscopy (EIS), an investigation into the corrosion prevention properties of the metals aluminium (Al), mild steel (MS), ...
-
(2021)The stead-fast demand for sustainable lithium-ion batteries (LIB) with competitive electrochemical properties, safety, reduced costs, and long-life cycle, calls for intensive efforts towards the development of new battery ...
-
Density functional theory study of (110)B-MnO2, B-TiO, and b-VO2, surface in metal - air batteries (2017)Density functional theory (DFT) study is employed in order to investigate the surfaces of, β-MnO2, β-TiO2 and β-VO2 (β-MO2) which act as catalysts in Li/Na-air batteries. Adsorption and co-adsorption of metal (Li/Na) and ...
-
(2022)Water contamination caused by toxic elements has serious human health and ecological implications. The increasing quantity of toxic elements in surface and groundwater is currently an area of greater concern, especially ...
-
(2022)Calcium and magnesium are two dominant species that contribute to water hardness. The aim of this study was to develop a poly (vinylidene fluoride-co hexafluoropropylene) (PVDF-HFP) composite membrane for treatment of ...
-
(2022)The gas sensing performance of two-dimensional (2D) hexagonal boron nitride nanosheets (h-BNNSs) has being studied by means of computational and experimental methods. The structural, stability and vacancies properties ...
-
(2021)Breast cancer is a malignant tumour that starts in the cells of the breast. Many studies revealed aromatase (CYP19A1) and cyclin-dependent kinase 2 (CDK2) as possible therapeutic targets regarding breast cancer treatment, ...
-
(2017)The undoped ZnO nanoparticles, In or Co single doped ZnO nanoparticles and the In and Co combinational doped ZnO nanoparticles were synthesised through sol-gel technique. The samples were characterised using XRD, TEM, ...
-
Metal oxides modified multiwalled carbon nanotubes based biosensor for determination of hypoxanthine (2022)Heart and Stroke Foundation South Africa (HSFSA) reports that about 17.3% of deaths in the country are associated with heart-related diseases and this rate is expected to increase to 41% by the year 2030. This severe ...
-
(2022)The Two Rivers Platinum Mine (TRP) located in the Eastern Bushveld Igneous Complex is currently exploiting platinum-group elements (PGE) in the Upper Group 2 chromitite (UG2) Reef at the Dwarsrivier Farm. TRP has ...
-
(2020)The Glentig, Alma and Swaershoek Formations were deposited after the emplacement of the Bushveld igneous complex (BIC). The sediments accumulated in what is termed as the proto-basin of the Waterberg Group. The Glentig ...
-
(2021)The ab initio density functional theory and molecular dynamics approach have been used to study the properties of Zr-based systems. In particular Zr-Nb, Zr-Nb-X (X = Co and Sn). We have calculated the structural, ...
-
(2020)Titanium dioxide is among the most abundant materials and it has many of interesting physical and chemical properties (i.e., low density, high thermal and mechanical strength, insensitivity to corrosion) that make it a ...
-
(2021)First-principles density functional theory has been used to study the stabilities of binary TiPt, TiTa, TiNi and TiCo potential shape memory alloys. Furthermore, ternary alloys Ti50Pt50-xMx with V, Ta, Hf and quaternary ...
-
(2020)In this work, we present first-principles calculation on the structural, thermodynamic, mechanical and electronic stabilities of Fe-Al and FeAl-X (X: Pt, Pd, Ru and Ag) alloys at lower and high temperatures. These systems ...

-
(2021)Titanium is the most abundant element in the earth’s crust and can be produced as both a metal and in powder form. It finds applications in various industries such as in medical and aerospace, where the fabrication of ...
-
(2021)Globally and in most parts of South Africa, there is a trend of increasing shrub encroachment in savanna rangelands. A number of studies have investigated the impact of shrub encroachment on soil organic carbon content ...
