Background:

Silicon-based photovoltaic (PV) systems undergo a drop in real-time performance in the field when compared to the predicted “laboratory” performance. The effects of dynamic operational environments where these PV panels are deployed give rise to various fault conditions which reduce...

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...

Central to the wellbeing of any living organism is the nucleus of the cell. It stores and organises genetic information and protects this information from other cellular components. The nucleus also communicates with the rest of the cell, exchanges proteins and RNA, and facilitates several important...

Platinum chemotherapeutics are used especially in patients with highly metastatic triple-negative breast cancers (TNBC). The chemotherapy is non-selective and toxic causing negative side effects that have been well documented. TNBC also readily acquires resistance to platinum-based therapies...

Non-toxic biodegradable wound dressing that releases drugs in response to inflammation and mimics skin cells. This accelerates the healing process and results in minimal scar formation, allowing wounds to achieve optimal healing.

Despite the existence of sophisticated materials used in preparing...

Parkinson’s disease (PD) is the most frequent neurodegenerative disease of motor activity, with more than 10 million people worldwide suffering from the disease. One of the major causes of PD is a shortage of dopamine, which is important to motor functioning in the body. Additionally, in PD, a...

Atherosclerosis is a chronic, progressive disease which involves the blockage of the arteries, and is the major form of cardiovascular disease (CVD). It is often comorbid with obesity, insulin resistance and/or diabetes. This disease is the result of the formation of atherosclerotic plaques which...
