IAM performs classified research on behalf of the South African Defence Force that entails the use of pyrotechnics in specialized applications. However, the main client is AEL Mining Services. In this regard the research effort is focussed on the removal of all lead and toxic heavy metal compounds from mining detonators. IAM had reasonable technical success in this regard but further development work is required at AEL before industrialization can commence. In short, IAM has developed fast, medium and slow burning time delay compositions that are lead-free. It also succeeded in the development of a thermite system capable of initiating high explosives via an ultra-high temperature shock. This is significant as this makes it possible to eliminate the lead-containing primary explosives from the detonator train.

Hendrik: Insecticides

During 2010 IAM received funding support from Sasol towards the development of a long life mosquito net (LLIN), from the Bill & Melinda Gates Foundation for an insecticidal paint approach for indoor residual spray (IRS), and from Mozambique-South Africa to explore the use of local clays as controlled release devices for IRS insecticides.

The long-term hope is to replace DDT currently used in IRS practice with more benign alternatives. Current results indicate that this may indeed be possible. A low-cost way of stabilizing WHO-approved insecticides was identified and proven in Phase I laboratory tests. A low cost net design was found that also passed Phase I WHO Laboratory testing. The IAM also forms part of the soon-to-be-established Centre for Sustainable Malaria Control. Research funding for future LLIN and IRS work will be sought from various sources. The current plan foresees three product offerings: A multifilament knitted polypropylene-based LLIN, a non-DDT IRS, and a low-cost Netlon type net for indoor wall use. We are currently meeting and negotiating with the IDC, Sasol ChemCity and Moznet, a local company interested in local production of LLIN’s. A proposal was submitted to the Bill & Melinda Gates Foundation for Phase II & III field trials.

Hendrik: Carbon Chair Introduction

The SARChI Chair in Carbon Science and Technology was established in 2006 within the Institute. It was set up to provide research and training in carbon materials, particularly those relevant to the Pebble-bed Modular Reactor and related industries. Prof. Brian Rand, a world leader in carbon materials research, is the part-time Chair Holder. His brief includes mentoring Dr Manyala as his future successor.

During 2010 some Carbon Chair students visited international other Universities and research institutions to perform research related to their projects. Mr Fabiane spent some time at the University of Pennsylvania, USA; Mr Hlatshwayo worked at the Institute of Polymer Research in Dresden Germany. Several students present papers at international conferences, notably the annual Carbon Conference. One of the students, M Badenhorst even gave a keynote lecture on graphite oxidation at the 2010 Carbon Conference held in Clemson, USA. While several conference contributions were delivered, the Carbon Chair only published one journal paper. However, most of the students will be completing their studies this year and it is anticipated that up to 10 publications could be submitted before the end of the year.
