The board of the Suid-Afrikaanse Akademie vir Wetenskap en Kuns (SAAWK) recently (22 April) announced the winners of the 2022 prizes. The academy, which was established in 1901, aims to promote the use of Afrikaans in science and the arts.

Havenga Prize for Physical Sciences

Prof Hendrik Swart, NRF B1-rated researcher, SARChI Research Chair in Solid-state Luminescent and Advanced Materials, and Senior Professor in the Department of Physics at the University of the Free State (UFS), received the prestigious Havenga Prize for Physical Sciences.

He says it is an honour to receive this award. “When I look at the list of names that have received the award in the past, I am very humbled and surprised to receive such an award.”

The Havenga Prize, for which candidates are specifically judged on research publications and evidence of their promotion of Afrikaans, has been awarded annually for the past 77 years for original research in the natural sciences or a technical field. 

A collaboration with researchers from the Nelson Mandela University (NMU) on semiconductor materials that improve the efficiency of solar cells, resulted in Prof Japie Engelbrecht (Emeritus Professor, NMU) nominating Prof Swart for this award. He is involved in an NRF collaborative research project with NMU and Linköping University in Sweden.

Prof Swart has played an important role in the acquisition of numerous research devices for analysing the thin layer of phosphor, and the semiconductor devices that can be made from such materials. His research and zeal for his work led to the establishment of the national nano-surface characterisation facility (NNSCF) containing state-of-the-art surface characterisation equipment. 

The PHI Quantes XPS system, for instance, is the first in Africa and one of only 20 in the world. The Quantes XPS system uses X-rays to determine the chemical composition of molecules on the surface of a sample. The system is unique in the sense that it also has an extra X-ray source that can determine the chemical state below the surface, which was not possible in the past. This will help to dictate the position of defects in phosphor materials, which will consequently enable the department to create better phosphor for solid-state lighting as well as solar cell applications.

The most meaningful for him, however, was the production of several well-trained postgraduate students and the generation of high-impact, well-cited scientific publications.

This award, one of several awards he has received during his career, does not signify the end of the road. On the contrary, he is looking forward to improving solar cells by using the phosphor materials they have manufactured, applying it on glass windows doped with phosphors to generate electricity.

NP van Wyk Louw Medal and Alba Bouwer Prize for children's literature

The NP van Wyk Louw Medal was awarded to Prof Hennie van Coller, a researcher who is also affiliated to the UFS. Prof Van Coller, currently an emeritus outstanding professor and research fellow at the university, was a former Head of the UFS Department of Afrikaans and Dutch, German and French, as well as Chairperson of SAAWK. He is known for his impact on the literary world, both locally and internationally, through the quality of his scientific articles and books. 

According to SAAWK, the body awards the NP van Wyk Louw Medal for a person’s creative contributions to the exploitation, organisation, and continuous development of a section of the humanities, significantly contributing to the advancement of the humanities.

Jaco Jacobs, the children’s author of more than 170 books who recently presented the 35th DF Malherbe Memorial Lecture at the UFS, was also awarded for his work. Jacobs, also a UFS alumnus, received the Alba Bouwer Prize for children's literature. The prize, which is awarded every three years, was presented to Jacobs for the book Die boekwinkel tussen die wolke, written during the COVID-19 lockdown period. 

SAAWK will present the awards later this year during two virtual award ceremonies in July.

Prestige Scholar and lecturer of African/South African History at the UFS, Dr Chitja Twala, was recently accepted as a Visiting Fellow at the Harvard Graduate School of Arts and Sciences (GSAS).

A Visiting Fellow status is available to individuals holding a doctoral degree to pursue independent research at Harvard. The Fellowship is for non-degree purposes but aims at the enhancement and further intellectual development of those involved. It focuses on enrichment and development programmes.

Twala was appointed in the Department of History at the UFS in the beginning of 2003. His research field is Liberation History, with specific reference to the liberation movements on the SADC region. He has published extensively on this field and presented papers in local and international conferences.

“I applied (to Harvard GSAS) in April 2014 for the Fellowship through the South Africa Harvard Fellowship Programme,” says Twala.

“After being successful in the interviews conducted by the GSAS panel in July 2014, I had to apply for admission in the Department of African and African American Studies at Harvard, and got accepted for the Fall Semester of 2015.”

At Harvard, Twala will be mentored by Prof Emmanuel Akyeampong (African History Expert).

“Firstly, my main assignment will be to grasp a much deeper theoretical knowledge/framework in historical studies and a broader repertoire of methodologies in the field of African History. Secondly, if time permits, I will be presenting seminars and attending some in a very challenging, stimulating, and intellectually demanding environment where my ideas can be tested and expanded. Thirdly, I will be exposed to new trends as far as African historiography is concerned. Lastly, I will informally engage and exchange some ideas with some experts in the field of African History.”

The programme was recommended to Twala by the Vice-Chancellor and Rector, Prof Jonathan Jansen and Prof Ian Phimister, Centre for Africa Studies Senior Professor at UFS.

“As per the priorities of the Prestige Scholarship Programme, the Fellowship will assist in inculcating in me the intellectual breadth and depth required to pose critical questions and generate ground-breaking knowledge for History as a discipline. It is important for the UFS to establish and sustain international networks with other leading universities and scholars around the world.

“I applied for this Fellowship in order to advance further and broaden the scope in the three areas of scholarship in higher education: discovery, teaching, and public engagement,” says Twala.

Twala will be leaving for Harvard by mid-August and will return by the end of December 2015.
