The North-West University has developed a method in which municipal wastewater is treated to remove ammonia and phosphate while simultaneously recovering struvite as a byproduct. Struvite is used to reduce the acidity of acidity of the acid mine drainage water which leads to precipitate metal
Chalcopyrite is a common but low-grade copper ore, and NWU researchers have developed an innovative method to improve copper dissolution and extraction from this mineral. This is achieved by harnessing galvanic interactions between chalcopyrite and magnetite, they achieved more efficient copper
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
The multi-tubular fixed-bed reactor is one of the most successful reactors used in a chemical process. However, hot spots can be formed easily in the fixed bed in a highly exothermic reaction system because of the relatively low heat transfer capacity of the tubular reactor. It is widely reported
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

This invention relates to a Femtosecond Laser-based method for the fabrication of micro- and nano-constriction type structures on a YBa2Cu3O7-x Superconducting thin film and to a new superconductor device. According to one aspect of the invention, there is a method of manufacturing micro- and nano
The invention provides a silicon pn-based device with different dopant and impurity implanted concentrations stra­tegically placed in the device, the pn junction being reverse biased, such that the 650 nm optical emission is stimulated and enhanced. The Light-Emitting Diode (LED) Grow Lights Market
The technology involves a method and an apparatus for treating a fluid, using nanoscience. Impurities in the fluid are trapped by nanoparticles. The fluid is contained in a reactor that includes a moving magnetic system. When the reactor is in use, the moving magnetic system excites the charged
The invention relates to the use of maghemite nanoparticles at pH less than 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In conventional AMD treatment, these pollutants are only removed at higher pH, and that requires costly alkaline
The invention relates to a membrane technology developed using polymeric material, to recover crude oil found in water due to spillages. Although several techniques have been employed for removing crude oil from bodies of water, these techniques are either focused on dissolving the spilled oil
The invention relates to the design of a robust membrane for desalination, using membrane distillation (MD). Although MD technology has advanced over the years, its industrial application for the treatment of brackish water and seawater continues to lag behind. This invention exhibits advantages
