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

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 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
