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.

Prof Hendrik Swart richly contributes to research of phosphors

Since his appointment as the South African Research Chairs Initiative (SARChI) Chair, there has been a sharp increase in the number of papers and publications by Prof Hendrik Swart, Senior Professor in the Department of Physics at the University of the Free State (UFS). From January this year, he has already published 78 articles. Some of the journals that has published his work, includes:

• Nanotechnology (impact of 3.67)
• Dalton Transactions (impact of 4.097)
• Sensors and Actuators B: Chemical (impact 3.84)

“My biggest success, however, is the powerful group of researchers we have built over the years. Staff, postdocs and students – without them it would have been impossible. I am therefore much indebted to my groups on both the Bloemfontein and Qwaqwa Campuses.

“The good apparatus we acquired via a sponsorship from the National Research Foundation and Sasol is also one of the main reasons for this. The financial support I get from the university’s research office is of course also a contributing factor,” he says.

For the past 20 years, Prof Swart has been conducting research on any substance that glows. “I only adjust the focus to fit in with current trends,” he says.

Prof Swart believes that his research will make a contribution to the fundamental knowledge about phosphors, as well as to the training of good students for the academic and industrial world on the outside. For the man on the street, his research translates into better, brighter lights that use less energy.

His more recent research focuses on the development of nano-phosphors for light-emitting diodes (LEDS) and organic light-emitting diodes (OLED).

Prof Swart has presented papers on his research not only nationally, but all over the world – including countries in Europe and the East. Some of the most recent papers presented by him and his colleagues/postgraduate students include:

• Applications of AES, XPS and TOF SIMS to phosphor materials at die 15th European Conference on Applications of Surface and Interface Analysis 2013 in Forte Village Resort, Sardinia, Italy.
• Luminescent properties of phosphor nano thin films at the first International Symposium on Nanoparticles/Nanomaterials and Applications in Caparica (Lisbon, Portugal), where he was an invited speaker.
• Role of surface and deep-level defects on the emission of nano metal oxides at the 2014 NanoAfrica international conference, Vanderbijlpark, South Africa, where he delivered the keynote address.
• PHI systems and their modifications at KOVSIES at the PHI European User Meeting in Ismaning (Munich), Germany, where he was invited to speak.

Prof Swart also delivered the keynote address at the SETCOR International Conference on Smart Materials and Surfaces in Bangkok, Thailand. His lecture was titled, ‘Role of surface and deep-level defects on the emission and degradation of phosphor materials’.
