The invention relates to the use of maghemite nanoparticles at pH less than 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In conventional AMD treatment, these pollutants are only removed at higher pH, and that requires costly alkaline

This system involves the process of taking soil samples from a potential building site, mixes it with water and then the sedimentation process is evaluated by a camera and analysed to determine how much clay is in the soil sample. This in turn will then provide the engineers with information on what

Postharvest table grapes are susceptible to fungal infection even when stored at the optimal temperature of −0.5°C. The most important pathogen of stored Table Grapes is grey mould, which is caused by Botrytis cinerea. Some countries fumigate their grapes with sulphur dioxide gas. However, if the

The Bambara Groundnut, or round bean, is widespread in Africa where it is known by various names. It has potential as a cash crop, owing to its nutritional composition, functional properties and antioxidant potential. Consequently, we at CPUT have used the Bambara Groundnut as a raw material to

The invention relates to a novel process of partial oxidation of un-agglomerated chromite ore in ferrochrome production processes. The process includes the steps: Providing a source of un-agglomerated chromite ore; subjecting the source of un-agglomerated chromite ore to pre-oxidation at a

The North-West University (NWU) has pioneered the novel use of Europium-Tellurium-Oxide (ETO) in the production of clean energy. ETO is a light-chargeable catalyst material that exhibits sustained and enhanced activity after light excitation has ended. Its unique characteristics present an

The Agricultural Research Council - Vegetable and Ornamental Plants ( ARC-VOP), which has a solid reputation as a leader in sweet potato R&D, has developed a new variety Khumo orange-fleshed sweet potato. A 60-gram serving of boiled roots of variety Khumo, supplies the recommended daily allowance

The cost of building materials contributes significantly to overall construction costs, with ordinary Portland cement (OPC) being one of the main components. The production of OPC is not environmentally friendly. It is energy-intensive, uses natural resources such as limestone, and produces high

Currently, the ARC have three commercial cultivars, Ratel, Steenbok and Tredou. Ratel consists of a medium growth period whereas Steenbok consists of a short growth period with good drought tolerance making it suitable for areas with a dry climate. Tredou is the newest addition to the ARC cultivar

Fly ash, is a waste by-product from the coal-fired electricity generating stations. Power stations need to dispose of the fly ash in a safe and environmentally friendly manner, making the need to utilize fly ash important. The production of zeolites is one way to beneficiate the fly ash waste where

Academic staff rating index (AR Index) is an interactive platform for supervision management. It is designed to enhance the student-supervisor relationship while also providing a rating index for supervisors. AR index aims to improve transparency and quality of academic student supervision by

Floatation Device is a system that acts as an anchor and elevator for equipment, shacks and mobile houses that would otherwise be affected by flooding. During the rainy season, the Floatation Device elevates the items away above the stormwater and provides stability to secure items from damage or
