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...

Researchers at Stellenbosch University have developed a groundbreaking new polymer having permanent antimicrobial properties. The compound can be spun into nanofibers for the production of filter elements or membranes, which successfully filter out micro-organisms and eliminate harmful bacteria.

A...

Power plant efficiency is generally determined by projected electricity tariffs and power plant life cycle costs during the design phase. This technology can be installed below wet cooling tower fills to significantly enhance the thermal performance of the cooling towers, resulting in a reduction in...

 

A cost-effective, highly efficacious trough assembly for collecting and removing drops with minimal air-side pressure drops for use in evaporative heat exchangers or cooling towers. The innovation reduces water consumption and required fan power. The elimination of a rain zone reduces the...

 

Short chain fructooligosaccharides (scFOS) are prebiotics used as a food supplement to improve dietary health in humans and animals. FOS are also used in the food industry as low-calorie sweeteners and added to food products to improve their organoleptic properties.

Global demand for FOS is...

Irrigation is an essential part of commercial agriculture. The water and energy used in typical large-scale irrigation systems can be substantial. As water becomes a scarcer resource its responsible use and conservation become imperative. The same is true of energy especially in territories where...

The researchers at Stellenbosch University have developed a technology for the radiometric correction of high spatial resolution imagery (aerial or UAV).  The imagery is calibrated to approximate surface reflectance by fusing with concurrent and collocated satellite imagery.  The technique allows...

The mobile application teaches fundamental computer programming concepts in a competitive, engaging, and playful way. Designed for students aged 10 to 14, the app features a military tank navigating through a maze, following directions provided by physical puzzle tokens. With 20 levels, players...

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...
