Innovations

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

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 continues to lag behind. This invention exhibits advantages

This technology provides a method for making a nanofluid by nuclear irradiating a mixture of a base fluid and precursor to form the nanofluid. Nanofluids exhibit superior thermal properties such as enhanced thermal conductivity, viscosity, heat transfer coefficient, dielectric strength, etc. However

The technology relates to a sol-gel based, uniform carbon-coating method for producing high-performance lithium-ion batteries. This method makes use of organic phosphoric acid as carbon and phosphoric sources to produce uniformly carbon-coated lithium-ion batteries that overcome the challenges of

The invention relates to an energy-generating system that makes use of polyethylene plastics (that would otherwise result in environmental pollution) to produce synthesis gas (syngas). Unlike conventional gasification systems that rely on oxygen, this system ensures that the gasification of

The technology relates to a system which harvests thermal energy from various sources (e.g., sunlight, cars, power plants, factories and other industries) and converts it into electricity. In this system, heat energy is harvested and then stored in a storage tank, using water as energy storage

The invention relates to a low-cost, portable, self-aligning rooftop wind turbine designed to capture moderate-velocity wind and generate electricity efficiently for household use. Current large-scale wind turbines in South Africa are located far field and the energy generated must be transported

The technology relates to an upright tubular fixed-bed reactor body comprising a heat -dissipating pipe, which extends from the reactor tube wall, to ensure that heat is effectively transferred in highly exothermic reactors such as Ficher-Tropsch, which are prone to heat build-up. The heat pipe is

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 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

LeguPro is a protein-rich pasta, which is produced from non-traditional pasta ingredients such as peanuts, soybeans, and chickpeas. It is a cost-effective nutrient-dense high protein, healthy instant noodle product and aims to give consumers an alternative staple food product to be consumed as is or
