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

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

This novel system allows for digital monitoring of payloads on heavy vehicles and avoids repetitive, physical weighing of compliant vehicles at static weighbridges to check overloading status. This is achieved by digitally linking all weighbridges and existing or new cameras on a specific corridor

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

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

Green Coal is environmentally friendly coal briquettes produced from discarded fine coal, bio-char material, and proprietary chemical binders. The briquette reduces sulphur emissions during combustion by approximately 50%, while also increasing the burning effectiveness. The bio-char addition to the

Coarse particle transportation is essential for moving slurries, or fluids containing very high concentrations of pulverised solids, for example, hydraulic transport of coal ore or waste materials. Due to a scarcity of water and a high concentration of the solid particles, pipe blockages are common
