The North-West University has developed a method in which municipal wastewater is treated to remove ammonia and phosphate while simultaneously recovering struvite as a byproduct. Struvite is used to reduce the acidity of acidity of the acid mine drainage water which leads to precipitate metal
Chalcopyrite is a common but low-grade copper ore, and NWU researchers have developed an innovative method to improve copper dissolution and extraction from this mineral. This is achieved by harnessing galvanic interactions between chalcopyrite and magnetite, they achieved more efficient copper
Hysteroscopy is a procedure that requires the direct visualization of the uterine cavity to diagnose and treat abnormal uterine conditions. Health professionals regard it as the gold‑ standard for diagnosis because of its effectiveness and efficiency. Traditional hysteroscopy systems, and the
Our invention consists of an array of Inertial Measurement Unit (IMU) sensors that are synchronized with one another. The IMU sensors measure the inertia and position of the subject within a space. The IMUs’ output is their collective measurement of inertia and forces, generating big data. The data
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
Background: Biomedical studies (e.g., prosthetic development and injury rehabilitation), sports science research, high-performance optimization research and assessments, and bipedal or quadraped movement measurement often require accurate measurement of the forces exerted by the subject being

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

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

Green Clean Surfaces for Safe Food Preparation Nutridx® is a disinfectant enhanced by the addition of a natural anti-microbial compound. It has been specifically formulated to disinfect and sterilise of food and food processing equipment as well as internal and external hard surfaces. It has been

Sol-gel Long Lasting Power These long-lasting and significantly safer batteries are novel because of their sol-gel base. A uniform carbon coating process produces high-performance lithium-ion batteries. This method makes use of organic phosphoric acid as carbon and phosphoric sources to produce
