Prof Rodney Moffett was presented with the Silver Medal Award. At the ceremony were, from the left: Prof Glynis Goodman-Cron, SAAB President, Prof Rodney Moffett, and Prof Sandy-Lynn Steenhuisen.

Prof Rodney Moffett, Honorary Research Fellow in the Department of Plant Sciences at the University of the Free State (UFS) and Top Research Fellow in the Afromontane Research Unit (2018-2019) on the UFS Qwaqwa Campus, was recently awarded a Silver Medal from the South African Association of Botanists (SAAB) at their 48th annual conference that took place in Polokwane.

Prof Sandy-Lynn Steenhuisen, Subject Head and Associate Professor in the Department of Plant Sciences on the UFS Qwaqwa Campus, says, “It was an absolute joy and honour to be able to nominate and present a SAAB Silver Medal to Prof Moffett, who is an iconic figure and friend in our department. I was so happy that he could receive his award in person, with his daughter visiting from the United Kingdom. He inspires my research group so much with his knowledge of plants of the Eastern Free State and through the wealth of specimens he’s contributed to the QWA herbarium.”

The conference with the theme, ‘Plants, Health and Prosperity’, was hosted by the University of Limpopo’s Faculty of Science and Agriculture under the School of Molecular and Life Sciences in the Department of Biodiversity.

Outstanding research contributions 

According to Prof Steenhuisen, Prof Moffett received the Silver Medal Award for his outstanding research that contributed to the advancement of botany and plant sciences in South Africa.

Since his retirement, Prof Moffett has published a number of book chapters, books, reports, and articles on various aspects of fauna and flora. 

He sole-authored eight books and authored/co-authored more than 36 peer-reviewed articles in scientific journals covering mainly the taxonomy of plant genera such as Sarcocaulon, Rhus, and Searsia, and checklists of vascular plants and their medicinal uses for the Qwaqwa and Lesotho regions. 

Around 2006, Prof Moffett pursued his passion to document and describe the ethnobotanical uses of plants used by the Basotho people of Lesotho and South Africa. His books focused, for instance, on the natural history and Sesotho names of the plants used by the Basotho of the Eastern Free State and their ethnobotanical uses, the taxonomic works on the grasses of the Eastern Free State (still the most detailed grass identification guide for the area to date), and the flora and fauna of the Clarens Village Conservancy (a field guide). 

Prof Moffett has also published a scientific bibliography of the Drakensberg, Malotis and adjacent lowlands, which Prof Steenhuisen describes as “a mammoth task and one which he is continually updating and expanding, with another volume in preparation”.

Prof Steenhuisen, who nominated Prof Moffett for the Silver Medal Award, says that as a highly respected naturalist in the Qwaqwa region, he is continually consulted by conservation authorities, researchers, and postgraduate students on the flora of the area. He also regularly presents his research at garden and botanical societies. 

Among the books he has published are Sesotho names of plants and animals and plants used by the Basotho (2010), A biographical dictionary of contributors to the natural history of the Free State and Lesotho (2014), and Meriana ya dimela tsa Basotho – Basotho medicinal plants (2016 and 2020). In 2020, he also published A Scientific Bibliography of the Drakensberg, Maloti and adjacent Lowlands.

Prof Steenhuisen states that Prof Moffett’s books are treasured resources for anyone working in the Maloti-Drakensberg area. 

Best poster presentation

Joining researchers, postgraduate students, and experts from other universities and organisations at the conference, was the Plant Ecology Research Group of Prof Steenhuisen, her postgraduate students, and a postdoctoral fellow involved in invasive species and climate change research. Postgraduates from three other research groups (Plant Biotechnology, Proteomics, and Ethnobotany supervised by Dr Arun Gokul, Dr Rudo Ngara, and Prof Anofi Ashafa) on the Qwaqwa Campus also attended the conference. 

Dr Makoena Moloi, Senior Lecturer in the Department of Plant Sciences on the Bloemfontein Campus, and her postgraduate students researching aspects of plant ecophysiology, were also present at the conference, together with master’s candidate Orateng Sedimo, who is supervised by Dr Lize Joubert, Senior Lecturer in the department. Sedimo presented his honours research and won a prize for presenting the best Honours poster in the category Molecular Systematics. 

Besides being well-represented at the 48th SAAB annual conference and being awarded for its outstanding contributions to botany and plant sciences, academics from the UFS had the opportunity to learn from and network with some of the best scientists in the field. This included A1-rated scientist, Prof Steven Johnson from the University of KwaZulu-Natal, (Prof Steenhuisen’s supervisor for her PhD), and B2-rated Prof Anton Pauw from Stellenbosch University. Prof Johnson and Prof Pauw were respectively awarded a Gold and second Silver Medal from SAAB.

UFS boasts with most advanced chemical research apparatus in Africa 

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie.  The NMR is used to analyse molecular structures. 

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa.  The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research.  We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard.  Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around.  I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million.  With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level.  Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes. 
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.  
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry.  These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples. 

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
