(2021)Water pollution associated with dyes and bacteria has become a concern to researchers due to lack of quality sanitation. South Africa falls amongst the water scarce countries. Thus, it is important to develop materials ...
-
(2021)Titanium metal and its alloy components find extensive applications in various industries such as aerospace, medicine and automotive due to its light weight-strength ratio. More importantly, titanium-based components with ...
-
(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, ...
-
Synthesis of quinoxaline compounds and their medicinal properties against mycobacterium tuberculosis (2019)In an attempt to synthesise quinoxaline-ferrocene compounds with antimycobacterial activity; a series of quinoxaline alkynyl derivatives were successfully synthesised from 3- (quinoxalin-3-yl)prop-2-yn-1-ol 86A and ...
-
(2020)An extensive search for a highly efficient, reusable, and non-toxic adsorbent materials for the removal of organic dyes from wastewater continues to be of great importance to the world. Activated carbon is the most ...
-
(2020)The interest on the use of proton exchange membrane (PEM) fuel cells for vehicle application has increase due to its efficiency, high power density and rapid start up. The on-board reforming process is used to generate ...
-
(2021)Fusarium species are among pathogenic organisms responsible for massive yield and quality losses in crop production. They cause crop diseases in the field and during storage, and some species are capable of producing ...
-
(2019)Imidazolyl-ethanamine Schiff base ligands of the N^N type were prepared by condensation reaction of histamine dihydrochloride with para-substituted aldehyde derivatives to yield: (E)-N-benzylidene-2-(1H-imidazol-4-yl)ethanamine ...
-
(2019)Nano-architecture structures of LixTiO2 are very promising as anode materials for lithium rechargeable batteries due to their ability to accommodate more lithium atoms and its ability to withstand high temperatures at ...
-
Polyaniline-zeolitic imidazolate framework composite nanofibers for hydrogen gas sensing application (2019)The quest for renewable, sustainable and environmentally compatible energy sources have been on-going for decades. Green technology such as hydrogen fuel cell has attained much attention as an alternative energy carrier ...
-
(2019)Rivers provide the main water sources for domestic, industrial, and irrigational purposes; however, they could be polluted by receiving wastes from municipal and industrial sources as well as runoff from agricultural land. ...
-
(2019)The increase in industrialisation such as mining and smelting activities is among the main sources of heavy metal pollution in the environment. These potentially toxic elements may be adsorbed directly by sediments of water ...
-
(University of Limpopo, 2019)Metal alloys are one of few materials that are capable of acting as catalyst precursors in Sabatier reactions, reducing poisonous CO2 gas into different useful hydrocarbons. However, optimal reduction of CO2 through these ...
-
(2019)This work presents the synthesis, characterisation and application of poly(vinylidene fluoride-co-hexafluropropylene) (PVDF-HFP) membrane prepared using a phaseinversion method. PVDF-HFP was blended with either functionalised ...
-
Palladium supported graphene oxide based metal organic framework composite for hydrogen technology (2019)The concept of sustainable energy development is one of the crucial topics of the 21st century. It has evolved into a guiding principle for a liveable future world where human needs are met while maintaining balance with ...
-
(2018)Beyond conventional intercalation chemistry, reaction of lithium with sulphur and oxygen (so-called “Li-air” batteries) have the potential to provide 2 to 5 times the energy density of current Li-ion battery systems. ...
-
(University of Limpopo, 2018)The dissertation describes the use of 2-benzenesulfonyloxyquinoxaline as a good coupling partner for different amine substrates. The palladium-mediated cross- coupling of aryl electrophiles and amines has become a widely ...
-
(2017)The presence of polycyclic aromatic hydrocarbons (PAHs) in the environment is of major concern since these compounds are highly persistent, toxic and wide spread pollutants. The aim of this study was to evaluate the levels ...
