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

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

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

The invention relates to the design of a robust membrane for desalination using membrane distillation (MD). Although MD technology has advanced over the years, its industrial application for the treatment of brackish water and seawater is still lagging. This invention exhibits advantages over the

The invention relates to a membrane technology developed using polymeric material to recover crude oil found in water due to spillages. Although several techniques have been employed for the removal of crude oil from water bodies, these techniques are either focused on dissolving the spilled oil

A method and apparatus for treating a fluid utilising nanoscience. The impurities in the fluid are trapped by the charged nanoparticles. The fluid is contained in a reactor that includes a moving magnetic system. When the reactor is in use, the moving magnetic system excites the charged

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

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

Water hyacinth (Eichhornia crassipes) is an aquatic weed which has one of the highest growth rates of all plants in the world. This fast-growing plant causes numerous problems in water bodies. These problems are related to navigation, recreation, irrigation and hydropower generation. The complete

Whartels™ is a maths board game designed for pre-primary and primary school learners and is aimed at improving children's maths achievement by focusing on cognitive aspects (maths concepts, metacognition and information processing) and neuropsychological facets (executive functioning, self

Almost 1 million South African Deaf people use South African Sign Language (SASL) as their primary means of communication as often they cannot speak, read nor read lips in any of the eleven official spoken/textual languages. This multi-ethnic group comprises Deaf South Africans who are largely
