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
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
This system provides accurate, digital, mid-upper arm measurements for screening of severe and acute malnutrition in children, as prescribed by the World Health Organisation (WHO). The system electronically captures the appropriate measurements and then proceeds to store and analyse the data using a
The digital infantometer provides accurate digital anthropometric measurement data for tracking the development of babies. The accurate measurement of weight, recumbent length and head circumference data are prescribed by the World Health Organisation (WHO) to assess the optimal growth of babies up
We have developed a universal, non-invasive remote condition monitoring system for ventilators. It provides remote monitoring of a heterogeneous/ multi-brand fleet of ventilators and patients’ respiratory function. In an already stretched healthcare system with limited human resources, this will

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 risk of occupational exposure to aerosolised bio-contaminants (potentially pathogenic viruses, bacteria and yeasts) in dentistry and the dental office environment has been highlighted in the literature for many years. Removal of these aerosols would decrease oral healthcare workers' risk of
The skin represents the first physical barrier to protect our bodies from harmful toxins, pathogens and dangerous environmental factors and plays an important role in social and visual experiences. South Africans have used traditional herbal medicinal products to increase immunity in
