Background The nucleus of a cell is central to the well-being of any living organism. It stores and organises information from other cellular components and protects this information. It communicates with the rest of the cell, exchanges RNA and facilitates several important processes. The nuclear

Background A Magnetic Resonance Imaging (MRI) scanner applies magnetic fields to a human or animal in order to generate an image of a specific region of the body. Due to a number of internal and external effects, these fields are never completely homogeneous. Distortion of the magnetic fields may

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

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 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

Water hyacinth (Eichhornia crassipes) is an aquatic weed which has one of the highest growth rates of all plants in the world. This fast-growing plant causes numerous problems in water bodies. These problems are related to navigation, recreation, irrigation and hydropower generation. The complete

South Africa harbours the highest number of rape incidents in the world, and sexual assault and rape cases in the entire SADC region are estimated at a minimum of 55 000 cases per year. Crime scene investigations utilise DNA technology on a regular basis. In cases of rape or sexual abuse, male

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
