Air quality is a concern worldwide. Consequently, efficient means to monitor air pollutants are critical. Current commercially available carbon-based sorbents used for sampling volatile organic compounds (VOCs) in air typically require solvent extraction prior to analysis, and they cannot be reused...

The invention is a leakage detection system for water pipelines installed in partially saturated soils. Most soils in South Africa and the rest of Africa are partially saturated because the water table is usually deep. Given the large amount of water lost from water distribution systems worldwide...

The invention relates to the scavenging of flavour compounds, typically undesirable or off-flavours, from a liquid beverage or foodstuff. In particular, the invention relates to the use of proteins for scavenging flavour compounds associated with dairy products, such as those which arise from heat...

The compound 1, 3, 6, 8–tetrahydroxy –2, 5-dimethoxyxanthone (formula (I)), having the ability to treat sexual dysfunction or erectile dysfuncion, is claimed. A process for obtaining a plant extract containing this compound, an extract and the use of this compound or extract in manufacturing a...

Improved Alkaline-Activated Slag Composition: Green Mortar Solution

The invention relates to the development of both an improved alkaline-activated slag (AAS) composition as well as a dry mixed ready-to-use alkaline-activated slag (AAS) composition. The ready-to-use AAS can be pre-packed into bags...

The invention relates to a process for producing protein microparticles in dilute organic acid solutions, without the presence of an alcohol such as ethanol. The microparticles are formed by dissolving a cereal prolamin protein in a concentrated organic acid solution with agitation, followed by...

Slow-Release Bicomponent Fibres: Teaming Up Against Malaria

This technology enables the controlled release of insect-repellent formulations by engineering the interactions between the components of the repellent mixture. The composite polymer fibres consist of a filament with a core containing a...

This invention relates to a system that continuously measures and monitors the dynamic behaviour of turbomachine blades in order to provide early warning of incipient blade failure. This would enable management to take corrective action in order to prevent failure and downtime. The system can be...

This invention relates to an alternate oxidant for a delay composition, and more particularly to a delay composition including a fuel and an oxidant in the form of antimony hexitatridecoxide having the formula Sb6O13. The invention also relates to the use of antimony hexitatridecoxides as an oxidant...

The invention

The invention uses plastic waste and Waste Foundry Sand (WFS) to produce building and construction material with a density of between 1700 and 1750 kg/m3. The plastic is melted and WFS is used to produce a paste for the moulding of building material.

Problem solved

Plastics are...

Invention

The invention relates to a food ink for use in a 3D printing process for the manufacture of food items, using extrusion-based printing techniques.

Problem solved

The printer can make foods with elaborate decorations and designs more easily than doing it by hand. It can enhance diversity...

Using a metallurgical waste product, the invention consists of a method to treat acidic water from mining sites. The treated water can be used for industrial applications or, with additional steps, be treated for potable usage.

Water is currently a scarce resource in South Africa, and the depletion...

The invention consists of a unique hinge mechanism as an alternative to existing spectacle hinge configurations. This mechanism facilitates the customisation of spectacle frames while also reducing costs associated with customisation.

The majority of eyewear frames uses hinging systems that are...

A new technology that provides the first ever high-throughput 3D imaging of locked diamonds within kimberlite rocks. Locked diamonds of up to 10cm in diameter can now be located within rocks before the crushing process begins.

Conventional sorting as well as other more recent sorting technologies...

A reusable sanitary pad that is uniquely designed to collect, retain and dispose of menstrual fluid. The reusable pad is used externally, it is hygienic and easy to clean.

The most commonly used and commercially available menstrual hygiene products in South Africa are tampons and sanitary pads. The...
