He obtained 80% of the R3.5 million for a Pegasus IV GCxGCMS instrument installed in 2009 at UP from this SASOL program. UP supplied the rest of the funds.

# Based largely on the capital injection from SASOL for the Pegasus instrument as well as the running support of my and Prof Philip de Vaal=s joint SASOL Fuels project, a Thrip application (Philip de Vaal main applicant) of 3:1 support was successful, providing R692 000 for the year 2010.

# He was invited to deliver a research lecture in June 2010 at the University of Rostock, Germany, and at the same time be the international external examiner of the PhD thesis of Werner Welthagen with the title: Development and Evaluation of Multidimensional Gas Chromatographic and Mass Spectrometric Techniques for the Analysis of Highly Complex Chemical Mixtures.

RESEARCH INTERESTS Design and evaluation of chromatographic and mass spectrometric equipment and techniques - this includes the application of these methods to non-routine analytical problems in research, industry and the environment: Χ In gas chromatography, various contributions were made towards the production of

capillary columns, including the manufacture and deactivation of electroformed Nickel tubing. Our >press-fit= coupling is not only offered by many international GC suppliers but was in the past also utilized to produce glass capillary columns with fused silica end- pieces for the local market. Further developments include high temperature stationary phases and temporary, dynamic modification of these to effect special selectivity. Optimisation of comprehensive GCxGC and its application to essential oil and petrochemical industries were investigated. A novel Supercritical Fluid Chromatograph (SFC) coupled comprehensively to a fast programmed gas chromatograph (SFC x GC) was designed and built.

Χ Ongoing attention is given to new concentration methods suitable for inlet techniques in

capillary GC and GC-MS. High capacity solvent effect inlets were developed with evaporation taking place in packed beds, rather than the traditional open tubular >retention gaps=. Presently, multichannel silicone rubber traps are developed for thermal desorption-injection of semi-volatile compounds. Areas of application are the determination of organic pollution (including TNT traces for forensic purposes) in air, soil and water samples as well as aroma analysis of wine, beer, fruit, flowers and

4

essential oils. The characterisation of beer volatiles by purge-and-trap analysis using silicone rubber traps has been a recent success. In situ derivatisation of polar molecules (including endocrine disrupters) after collection/concentration of environmental samples in silicone traps is being investigated. Provisional patents have been filed on (i) in situ laser spectroscopic screening of compounds inside the trap, (ii) GC fraction collection for off-line olfactometry and bio-assays and (iii) a simple technique for differentiating between particle associated vs non particle associated organic contaminants in air utilising the silicone rubber traps.

Χ Customized chromatographic systems were developed for automated analysis or in-line

process control in various South African industries: At the AEC a GC was constructed for the analysis of the nuclear spin isomers, o- and p-hydrogen, in a Raman cell for frequency shifting of the 10 μm CO2 laser output. At SASOL a process analyser was developed for the rapid analysis of ppb levels of sulphur compounds in synthesis gas; a supercritical fluid chromatography method was also developed for the class separation of petrochemical fractions and for coupling to GC-MS (Fischer Tropsch products). For ISCOR, gas chromatographic methods were developed for the complete analysis of coke oven gas and for the rapid characterization of rolling mill oils. At the SAB, a GC system was developed for the monitoring of changes taking place in sulphur compounds at the ppb level, during ageing of beer in the glass bottle.

Χ Time-of-flight mass spectrometry (TOFMS) and laser ionization methods are areas of

intense interest. A TOFMS was jointly built with the AEC for the monitoring of laser based, isotope separation techniques. TOFMS systems were developed, together with a research team in Munich (GSF-Research Centre for Environment and Health, Institute for Ecological Chemistry and the Technical University of Munich, Institute for Physical and Theoretical Chemistry), for improved environmental trace analysis and incinerator exhaust-gas monitoring. The aim with laser TOF instruments is to enhance both the sensitivity and the selectivity of mass spectrometry. Both can be achieved by Resonance Enhanced Multiphoton Ionization (REMPI), a process that can produce up to 100% ionisation efficiency within a pulsed laser beam (compared to 10-5 efficiency in an electron impact source) combined with extreme selectivity arising from the selective absorption of the first laser photon by high resolution UV spectroscopic resonance of rotationally and vibrationally cooled molecules. The cooling, typically down to less than 50 K, is achieved gas dynamically by expansion through a nozzle into the vacuum of the mass spectrometer ion source. REMPI TOF MS is thus a fully two dimensional (high resolution UV spectroscopy - Mass Spectrometry) technique. 5 Patents together reflect the input in developing this (presently exotic, research) technique into a practical analytical tool, including coupling to gas chromatography.

Chemistry Lecturer: The National University of Lesotho from March 1995 to December 2004

Teaching Analytical Chemistry and Laboratory management at all levels and managing the faculty as the deputy dean.

Teaching Assistant: The National University of Lesotho, July1989 to August 1990- and throughout the study leave-1990 TO 1995

5. DEVELOPMENT AND SUSTAINABILITY CONSULTING SKILLS

� More than ten years of consulting experience:

Proficient in Environmental Management, Occupational Health and Safety, Waste

management and Sustainable Development Issues including International Conventions

thereof.

Expertise in Projects Management, Proposals and Reports Writing

Feasibility Studies and Strategy Development

Training in ALL these Fields, Workshop and Seminar Facilitation,

6. LIFETIME ACHIEVEMENTS

I worked my way up to the middle management of the University; in the office of the Deputy

Dean, while there we managed to procure a Science building that accommodated the Physical Sciences laboratories and lecturers’ offices.

As a young scientist I was able to inspire a new thinking of the scientific school for

development of Lesotho. This is that, service delivery has to be diverse and should not be limited within the taught discipline; “A Scientist is an all-rounder” this is now seen through diverse occupations of the science generation of today. I taught at University level for over ten years.

I was able to break away from the norm of being employed by being an employer and

starting a consulting company. The company now offers all relevant fields and themes of sustainable development, and has attracted clients in Private sector, Governments and International Organizations.

As a consultant I have been able to undertake diverse jobs in Economic and Policy analyses,

Health and Environment, History and Cultural Heritage all the way into fine arts. I have developed strategies in the fields of Agriculture, Health, Cultural Heritage, Biotechnology and Environment.

University of the Western Cape. Project: Synthesis and Characterization anthracene sulfonic Acid-doped polyaniline Nanostructures and their application as amperometric biosensors.

July, 2007 Department of Chemistry, University of Pennsylvania, USA in Professor Michael Therien’s Laboratory, Project, synthesis of porphyrins nanostructures using water soluble meso-tetra(4-sulfonatophenyl)porphyrin (H4TPPS4

2-) and meso-tetra(4-pyridyl)porphyrin (H2TPyP2

+)

July, 2008 iThemba Labs, Material Science Group (MRG), I did some work on the synthesis and characterization of porphyrin nanostructure
