18 Prof Hattingh’s research interests are in the key areas of characterising the energy input, process interpretation by a novel NMMU developed "force footprint" model; linking process parameters with residual stresses mapping. The development of new leading edge techniques using the principal of friction hydro pillar processing as repair and joining technique is currently a high priority for Prof Hattingh’s research group. Evidence of the research impact can be seen in his participation and leadership in competitive peerreviewed European Union beam time applications over the past few years at the world-renowned ILL and ESRF facilities in France, who have provided over 38 days of synchrotron and 17 days neutron radiation beam time with a real facility cost of around £675 256 (R7.8 million). Prof Hattingh also serves on the Editorial Advisory Board of the International Journal of Fatigue published by ELSEVIER. Prof Tim Downing: C1 NMMU Research and Innovation Report 2011 - Research Overview Prof Tim Downing conducts research on fresh surface-water quality with specific reference to cyanobacterial toxins, their environmental fate, ecotoxicology, toxicology and human and animal exposure risks. In addition to evaluating the causes of cyanobacterially related mortalities in the Kruger National Park, evaluating the national cyanobacterial toxin risk and studying the physiological role of well-known cyanobacterial toxins within the producing organisms, his recent research activity has focused on the cyanobacterial metabolite ß-N-methylamino-L-alanine (BMAA), a neurotoxin linked to the development of the neurodegenerative disease, amyotrophic lateral sclerosis (ALS). In recent years, he has developed a robust and sensitive analytical method for this toxin and applied it to the evaluation of human exposure risk for this toxin from water sources and via trophic accumulation in ecosystems. In addition to showing unequivocally that BMAA is a cyanobacterial metabolite and determining the prevalence, incidence and distribution of BMAA producing cyanobacteria in South Africa, he has shown that human exposure is most likely via aerosol and ingestion of bioaccumulated toxin rather than via consumption of potable water. Work on ecotoxicology has resulted in a better understanding of both the environmental fate and potential ecological effects of this toxin. Much of the current research effort is on the biosynthesis, environmental regulation, and metabolic role of BMAA in cyanobacteria, human exposure evaluation, and the neurotoxic effects within model systems. Prof Thomas Gerber: C1 Prof Thomas Gerber has extensive experience in the synthesis of many classes of organic compounds and their interaction with Re and Tc in the oxidation states +1 and +V . These compounds include benzimidazoles,-oxazoles, and -thiazoles that have the potential application in the diagnosis of Alzheimer’s disease. Other ligands used were antipyrines, quinazolines, benzamides, imidazoles, pyrimidines and uracils among others. Prof Gerber in this research has demonstrated that the reaction of [ReO2(py)4]Cl with the tridentate N3 -donor Schiff base N-(2aminobenzylidene-1,2-diamine (H2L3) led to the formation of the rare oxo-free ‘3+3” rhenium (V) compound [Re(L3)2](ReO4. His current research focus is on oxo-free rhenium (V) compounds with metal -nitrogen multiple bonds, for example metal-hydrazido and metal-imido complexes. This research has shown that the reaction of 1, 2-diaminobenzene(H2dab) with trans -[ReOCl3(PPh3)2 in ethanol produces trans-[Re(dab)Cl3(PPh3)2], in which dab is coordinated as a monodentate imide. Additionally, Prof Gerber and his team of researchers have attempted the synthesis of the potentially tridentate Schiff base ligand H2OPhsal, which lead to the isolation of the zwitterion derivative H3ono. The reaction of H2ono with trans-[ReOBr3 (PPh3)2] surprisingly led to the isolation of the rhenium (III) complex [ReBr (PPh3)2(ono)] (1), which ono acts as a dianaionic tridentate ligand. The area of pursuit for the last eight years (2004 to date) has been an interest in the coordination chemistry of rhenium, which was mainly centred on its +V oxidation state, since it is easily accessible from the reduction of perrhenate (which is beneficial for its radio-pharmaceutical application), and is stabilised by a large variety of donor atoms. The study of ligands containing the amino group, especially aniline is an active research field in the coordination chemistry of rhenium, and Prof Gerber and his group have become the most active in this research niche internationally. Prof Geoff Booth: C2 At the beginning, Prof Geoff Booth had a number of diverse interests, which included lattices of radicals, as well as Generalised ADS. With the passage of time though, his focus shifted to near-rings and sandwich near-rings of continuous functions. He collaborated with Prof Peter Hall to study primeness, which hither to their research had not been studied. He looked more in-depth at both near-rings of continuous self-maps and sandwich near-rings of continuous functions. This kind of work has become his exclusive interest at present. He has attained some interesting results on strongly primeness, and has published results derived from such research. He has delivered papers at a number of international conferences, covering places such as Australia, Spain, Taiwan and Greece. The study of near-rings of continuous functions has proved interesting to him, because it provides a large number of examples of nearrings with a differing structure, and the second thing it does is provide a link between algebra and topology. This understanding will contribute to resolving some questions in near-ring theory. Prof Booth has also contributed significantly to the theory of lattices of radicals of associative rings with Halina France-Jackson.
Research Output Units The research output subsidy units allocated by the Department of Higher Education and Training (DHET) for research publications and graduating Masters and Doctoral students represents a crucial benchmark of research excellence and is based on successful Doctoral and Masters graduates and subsidies generated through academic publications. The monetary value of the subsidy from this source increased over the past three years as follows: R59 million (2010 based on 2008 outputs), R64 million (2011 based on 2009 outputs) and R78 million (2012 based on 2010 outputs). In 2010, there was a 13.6% increase to 255.51 units for research publications (books, conference proceedings and journal articles) compared to 224.01 units in 2009. This is remarkable given the fact that there was already a 22% increase from 2008 to 2009. Masters and Doctorate units decreased by 3.26% from 400.966 units in 2010 to 387.899 units in 2011. This was mainly due to a drop in the number of Doctoral candidates graduating from 64 in 2011 (class of 2010) to 59 graduating in 2012 (class of 2011).
