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...

UCT in partnership with Stellenbosch University have developed the technology, which has undergone field trials on municipal water networks using a prototype system. 

It is a system consisting of a field device and a back‑end information management system. The field device temporarily connects to...

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...

Moulds are hollowed-out blocks that are used as tools for the mass production of parts such as plastic bottles and automotive parts. These moulds are expensive to manufacture and are therefore designed to have a long service life.  Manufacturing industries thus seek cost-effective processes to...

The technology is a membrane for treating acid mine drainage that is reproducible and can handle large discharges of acid mine drainage. It is suitable for implementation in a filtration cartridge setup that allows for the reclamation of metals which can then be recycled and used for other...

This technology is a high-temperature self-repairing carbide ceramic matrix composite. It is produced using titanium and a porous CfC composite preform matrix. Titanium and the composite preform matrix are placed in a crucible and spark plasma sintering is used to melt titanium so that it...

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...

LeguPro is a protein-rich pasta that is produced from non-traditional pasta ingredients such as peanuts, soybeans and chickpeas. LeguPro is a cost-effective nutrient dense high protein healthy instant noodle product and aims to give consumers an alternative staple food product to be consumed as is...

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 risk of occupational exposure to aerosolised bio-contaminants (potentially pathogenic viruses, bacteria and yeasts) in dentistry and the dental office environment has been highlighted in the literature for many years. Removal of these aerosols would decrease oral healthcare workers' risk of...
