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...

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...

Background:

Obstructive Sleep Apnoea (OSA) is a debilitating condition with significant morbidity and mortality characterized by blockage of the upper airway during sleep as a result of collapse of the soft tissues in the throat. OSA affects approximately 6-8.5% of the adult population in western...

Conventional narrow-bandwidth low-noise amplifiers (LNA’s) can achieve noise figures close to the theoretical minimum noise figure of the high electron mobility transistor  (HEMT) devices that are being used (red curve). The wider the bandwidth, however, the more difficult it becomes to achieve a...

The North-West University has developed a universal, remote and digital interpretation system for PCR results that allows for point of care diagnosis. A difficulty in times of pandemic, for example, during the COVID-19 pandemic, is that there are large numbers of people requiring testing to identify...

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...

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.

UCT researchers...

Background

Globally, freshwater is a precious resource that needs to be managed properly. Considerable amounts of freshwater supplied via bulk distribution systems are lost through leakages in poorly maintained water network infrastructure. Utilities, network operators, and other relevant...

Many accidents in rural areas are caused by stray animals. These animals, mostly cows and donkeys, are integral to the livelihoods of the rural communities. Furthermore, accidents with large animals are often fatal for the driver or passengers of a car. Cars also sustain significant damage during...

Fly ash, is a waste by-product from the coal-fired electricity generating stations. Power stations need to dispose of the fly ash in a safe and environmentally friendly manner, making the need to utilize fly ash important. The production of zeolites is one way to beneficiate the fly ash waste where...
