The North-West University (NWU) has developed and patented a method for producing hydrogen via hydrolysis, using an activated aluminium compound. Technology Benefits: Aluminum also can be recycled after the hydrogen production process. Hydrogen can be produced under high pressure. By-products are

This technology utilises a microchannel reactor for the decomposition of ammonia, comprising two chambers: one for exothermic combustion of ammonia to generate heat. A second chamber of the reactor with a second catalyst receives a second stream of ammonia to provide endothermic decomposition of the

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

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

Almost 1 million South African Deaf people use South African Sign Language (SASL) as their primary means of communication as often they cannot speak, read nor read lips in any of the eleven official spoken/textual languages. This multi-ethnic group comprises Deaf South Africans who are largely

The technology is capable of treating high-temperature wastewater as a membrane for removing oil from wastewater One of the key challenges with membrane filtration devices is the issue of fouling and concentration gradient build-up on the surface of the membrane, which subsequently decreases its

Connecting Communities Zenzeleni is a solar-powered, community-owned Wifi telecommunications network solution providing affordable communications to remote rural areas. Through the use of wireless mesh networking, users are able to make free internal voice-over IP calls, while the cost of breakout

In the manufacture of textiles, clothing and leather goods, using a nanoparticle catalyst, this one-step wastewater treatment system activates a powerful oxidiser. This produces sulfate radicals in the wastewater which will degrade the inorganic pollutants. These highly reactive nanoparticles are
