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 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 CSIR has established a bioconversion platform that focuses on alternative pathways for chemical production. The platform is geared towards local production and replacing imports of bio-based platform chemicals, including lactic acid. This shift will have a direct impact on the bioeconomy. 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

Industrial electrowinning is one such example where archaic technology has become the norm, with innovation being limited simply because the process is “good enough”. After doing a fundamental analysis on the electrowinning process, the design team has invented a dynamic solution which improves on

Air quality is a concern worldwide. Consequently, efficient means to monitor air pollutants are critical. Current commercially available carbon-based sorbents used for sampling volatile organic compounds (VOCs) in air typically require solvent extraction prior to analysis, and they cannot be reused

Improved Alkaline-Activated Slag Composition: Green Mortar Solution The invention relates to the development of both an improved alkaline-activated slag (AAS) composition as well as a dry mixed ready-to-use alkaline-activated slag (AAS) composition. The ready-to-use AAS can be pre-packed into bags

Using a metallurgical waste product, the invention consists of a method to treat acidic water from mining sites. The treated water can be used for industrial applications or, with additional steps, be treated for potable usage. Water is currently a scarce resource in South Africa, and the depletion

A new technology that provides the first ever high-throughput 3D imaging of locked diamonds within kimberlite rocks. Locked diamonds of up to 10cm in diameter can now be located within rocks before the crushing process begins. Conventional sorting as well as other more recent sorting technologies

The researchers at Stellenbosch University have developed a technology for the radiometric correction of high spatial resolution imagery (aerial or UAV). The imagery is calibrated to approximate surface reflectance by fusing with concurrent and collocated satellite imagery. The technique allows the

PhenoLAB is an online web-based analyses platform and database for wine producers. PhenoLAB incorporates highly accurate, extensive and robust analyses methods based on absorbency values for determining tannins, colour density, anthocyanins and total phenolics levels in grapes, fermenting must and

A cost-effective tip appendage design that reduces tip leakage vortices in axial flow fans to improve fan performance. The appendage is robust in that it is applicable to various axial flow fan designs and can be installed on currently operational units through retrofitting due to its simplistic
