The inverse Class-F power amplifier (PA) comprises an appropriately biased GaN active device, input matching network, and output wave-shaping and matching network. The novel design of the wave-shaping and output matching network ensures minimal overlap of the drain voltage and current waveforms, and
The versatile micro-nutrient supplement developed at CPUT can be used in a variety of products such as biscuits, baby cereal, porridge, etc. All the ingredients are bio-available and contain natural vitamin E, pro-vitamin A, and other carotenes. Biscuits baked with this pre-mix were used in an
Medical Male Circumcision Underwear (MMC) is a specially designed male underwear developed to aid the healing process after circumcision. The underwear keeps the penis in an upright position, preventing downward and outward blood flow from the wound. Penile injuries associated with circumcision are

A novel bioreactor system that uses membranes to create a compartmentalised system where two or more species can be co-cultured without mixing of species, while ensuring rapid exchange of metabolites and proteins between compartments and shared medium composition. The system operates continuously
Many of the commonly used food preservatives and microbial agents are synthetic compounds. In recent years, there has been an increased interest in avoiding or eliminating the use of synthetic compounds and in developing and promoting the use of natural materials for use as antimicrobial agents
South Africa's manufacturing sector, particularly in automotive, aerospace, medical devices, and electronics, requires high-precision measurement tools. The proposed Coordinate Measuring Machine (CMM) addresses this need by offering enhanced accuracy and cost-effectiveness compared to traditional
The Vapour-Based Passive Multistage Solar Desalination System offers a sustainable and efficient solution for desalinating water using solar energy. The system is designed to operate off-grid, utilizing solar heat to drive the desalination process, making it ideal for remote areas where access to
Certain liquids, such as wine, are sensitive to contact with oxygen and may be degraded by oxidation, so winemakers usually take steps to limit or entirely prevent oxygen from contacting the wine. For example, inert gases may be used to displace oxygen. In reductive winemaking processes, oxygen is

In the era of COVID‑19, Personal Protective Equipment (PPE), and its fundamental role in the protection of clinicians have come to the forefront as an essential medical technology. While commonplace in many situations as a standard of care, i.e., theatre, ICU, etc., its fundamental role in the
HIV/AIDS continues to disproportionately impact sub-Saharan Africa, where it remains a leading cause of illness and death among children. Paediatric HIV progresses at an alarming rate, with 20–30% of untreated infants succumbing to the disease within their first year. Without timely intervention

The current patterns of production and consumption of conventional plastics are unsustainable. Conventional plastics are non-biodegradable, leading to visible pollution in soil, marine environments and the air when discarded, landfilled or burnt. Products that are practically non-recyclable, such as
This technology offers a next-generation creatine powder formulated with food-grade components that enable instant mixing in water and long-term shelf stability. When added to liquid, the powder disperses rapidly and forms a clear, grit-free solution within seconds, avoiding the sedimentation and
