Star-Formation and Radio-Astronomy
Star formation can be considered as one of the most basic processes in the Universe. It is hard to imagine a Universe without stars. Perhaps the most amazing aspect of the star formation process is that it takes matter which is at a very low density, of the order of hundred thousand molecules per cubic centimetre and which is very cold, about -…http://natural-sciences.nwu.ac.za/space-research/physics-in-application

Innovative Astro Tegnologies: Low Noise Amplifiers A novel Low Noise Amplifier (LNA) technique for radio telescopes (such as the planned SKA), that has lower noise over much broader bandwidths and at higher temperatures than standard LNA's, was developed. Due to the broad bandwidth, this technique makes it…http://natural-sciences.nwu.ac.za/space-research/contact-us

Background: Membrane Technology - Resource Benification
South Africa has significant reserves of various naturally occurring resources. While some materials can be easily purified from these resources other separations are notoriously difficult. For example, Zircon, the most important source for Zr worldwide, always contains a few percent of Hf.

H2 Production
In our group membrane based elctrolyzers are developed for the production of H2 using novel processes like the hybrid sulphur (HyS) process where the hydrogen is produced by the oxidation of SO2 in the presence of water forming H2SO4. Both new and existing membranes are screened for their suitability for this process in terms of…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/process-intensification
Process Intensification
Based on past experience on in-house manufactured zeolite coated ceramic membranes, current research is continuing on the use of zeolites and zeolitic membranes combining their catalytic properties as well as their ability to act as molecular sieves. /sites/natural-sciences.nwu.ac.za/files/files/CRB/imagesSintering…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/gas-separation
Gas Separation
While gas permeation studies form an intrinsic characterisation tool both for the inorganic as well as organic membranes for various applications, there are ongoing projects focussing specifically on the resolution of various perfluorinated compounds. These projects focus mainly on finding membrane based separation processes to replace…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background
