Background

Currently, there are two ways of administering anaesthesia: either by administering the anaesthetic agents by gas or through intravenous administration. The drawbacks of inhalation anaesthesia are that they can cause side effects, particularly respiratory[1], have a negative impact on...

A method of extracting beneficial compounds from moringa for addition in foods, drinks and dietary supplements to increase their vitamin content and their health benefits.

Plants, such as those of the Moringaceae family, contain compounds that have antioxidant and immune-boosting properties which...

Research on animals and pre-industrialized societies conducted by the University of the Witwatersrand, Johannesburg and the University of California, Los Angeles, has shown a strong correlation between Wet Bulb Globe Temperature ((WBGT) – a combination of ambient air temperature and humidity) and...

VeristicPrint Biometrics System is a software package that has the ability to acquire a coloured photograph of a finger through a digital imaging device (e.g. Smartphone, Webcam, Digital camera etc.) and converts it into a conventional grayscale fingerprint image. Furthermore, the biometric features...

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...
