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...

Diagnosis of a disease typically includes testing of patient samples on an appropriate diagnostic platform, and it is necessary to perform proficiency testing of these platforms regularly, so as to assure the accuracy of the results,  Professor Kana and his team at Wits have developed proficiency...

Treating relatively fine bone fractures is challenging, as mechanisms to promote and correct bone growth used in large fractures are not suitable. Wits researchers have developed an injectable compound which is liquid at room temperature and becomes solid at body temperature that meets this need. It...

Wits researchers have developed a compound for the treatment of age-related diseases, such as cancer and cellular ageing. The compound occurs naturally in the body, and reduces the effects of telomerase activity in cells in a manner that prevents ageing of the cells. The compound, a protein fragment...

Wits researchers have developed a kit for diagnosing cancer by detecting telomerase activity in cells using functionalized gold nanoparticles. The Ageing Related Disease Diagnostic (ARDD) telomerase assay will ultimately be easier to use, have a potentially longer shelf-life, and avoid the...

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 cost of building materials contributes significantly to overall construction costs, with ordinary Portland cement (OPC) being one of the main components.  The production of OPC is not environmentally friendly. It is energy-intensive, uses natural resources such as limestone and results in high...

With our society facing challenges related to sustainability i.e. resource depletion and waste accumulation, the future success of the chemical and polymer industries relies on the use of renewable feedstocks.

Lignin, one of the main components of non-edible lignocellulosic biomass shows great...

Background

Leak detection and management is an important topic in the management of water distribution systems. Various instruments and measurement techniques have been developed to identify the occurrences and locations of new leaks in large distribution systems and networks.
