Background:

Cellulose and Chitin are the two most abundant natural biopolymers in the world. Both are characterised as water‑insoluble in their natural states. 

Chitin is a white, hard, inelastic polysaccharide found primarily in the exoskeleton and internal structures of invertebrates such as...

One of the barriers to increasing microprocessing clock speed is the extreme difficulty to move heat out of the CPU chip. Wits researchers have developed a cold spraying heat exchanger manufacturing technique where thin layers of copper and aluminium are deposited on a copper substrate. De-alloying...

The North-West University (NWU) is pioneering 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...

Wits researchers have developed a water treatment plant which removes organic pollutants from municipal bulk water. The process is environmentally friendly, making use of sunlight to purify water, thus saving energy and eliminating the need to use chemicals. Its modular design allows for scaling...

The novel solar trough plant receiver is customizable based on the solar field needs, providing improvements in the harnessing of solar energy. Unlike conventional parabolic trough solar systems, it has a wider operational temperature range as well as high-efficiency levels which not only reduce...

Surfactants are amphipathic molecules with both hydrophilic and hydrophobic moieties that partition preferentially at the interface between fluid phases such as oil/water or air/water interfaces. Such characteristics confer excellent detergency, emulsifying, foaming, and dispersing traits, which...

The Explosives ICT Control System is a dedicated explosive control system developed for registered users of explosives such as mines and civil blasters for ordering, receipt, distribution and utilization of explosives as required by the Mine Health and Safety Act, and the Explosives Act. 

This...

BabyChecker is a low-cost ultrasound combined with Artificial Intelligence, and automatically detects maternal risk factors without the need of a trained specialist. It can be connected to a smartphone or tablet, which makes it a portable solution that can be used in remote areas that lack power...

There are approximately 1 million upper limb amputees across South Africa, with an estimate of another 5 million in the rest of Africa.  Amputees find available prostheses too expensive, uncomfortable and/or having limited functionality. This results in many amputees discarding their prostheses...

Monitoring location and activities of miners underground, as well as environmental information, is essential to ensure miner safety. Information transmission systems currently used in underground mines are not able to cost-effectively address this need.  Visible Light Communication (VLC) and Power...
