Ecotoxicology
Ecotoxicology is a scientific discipline which studies the effects of stressors on biological organisms. It integrates toxicology and ecology, predicting the effects of stressors across all levels of biological organisation from molecular level to whole communities and ecosystems. The current techniques, services, and organisms shown below…http://natural-sciences.nwu.ac.za/unit-environmental-sciences-and-management/staff

Prof Henning Krieg Henning Krieg completed his B.Sc. and B.Sc. Hons in South Africa before travelling on a Fulbright scholarship to the US where he completed his M.S. in Chemistry at Rutgers, the State University of New Jersey in 1994. He returned to South Africa where he completed his Ph.D. in 2000 at the North-West…http://natural-sciences.nwu.ac.za/crb/resource-benification
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. The…http://natural-sciences.nwu.ac.za/crb/research-groups/membrane-technology/background/resource-benification

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/space-research/outreach
