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 is still lagging. This invention exhibits advantages over the

The invention relates to the use of maghemite nanoparticles at pH < 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In a conventional way of AMD treatment, these pollutants are only removed at higher pH and requires costly alkaline chemicals

The technology relates to an application that allows the efficient delivery of groceries ordered online by using a car lift service from general road drivers. Unlike existing delivery applications, this platform does increase the reliance on dedicated delivery vehicles but makes use of a network of

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 technology relates to a new generation of telecommunications and data processing technology with improved wavelength sensitivity in the visible and near-infrared wavelengths range rather than microwave communication in 2–4 GHz. The technology provides the realisation of optical sources (LEDs)

A system which harvests thermal energy from various sources such as sunlight, cars, power plants, factories and other industries, and converts it into electricity. The harvested heat energy is stored in a storage tank, with water used as an energy storage medium. This then flows along a gradient to

A low-cost, portable, self-aligning rooftop wind turbine designed to capture moderate velocity wind and generate electricity efficiently for household use. Large-scale wind turbines in South Africa are located far afield, and the energy generated must be transported back to communities via huge

A method and apparatus for treating a fluid utilising nanoscience. The impurities in the fluid are trapped by the charged 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 entails an energy-generating system that makes use of polyethylene plastics that would otherwise result in environmental pollution to produce synthesis gas (syngas). Unlike conventional gasification systems that rely on oxygen, this system ensures that the gasification of polyethylene

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

T his technology relates to a novel process for a One-step Mass- Production of various nanofluids in a modified version of laser ablation in open atmosphere. According to a first aspect of the invention, there is provided with a method of producing a nanofluid, the method including laser ablating a

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
