Science for the Future (S4F) summit
Attending the Science for the Future (S4F) summit in the Centenary Complex on the Bloemfontein Campus were, from the left: Back: Dr Cobus van Breda (S4F Programme Director), Amaria Reynders (S4F Family Math Manager), Dr Glynnis Daries (Sol Plaatje University), Prof Francis Petersen (Rector and Vice-Chancellor of the UFS), Tarin Roberts (Nelson Mandela University), Adolph Tomes (Acting Chief Executive Office, SANRAL). In the front are, from the left: Prof Angela James (University of KwaZulu-Natal), Heidi Harper (General Manager Skills Development, SANRAL), Prof Jogymol Alex (Walter Sisulu University).

Teachers from across the country and representatives of six other universities recently gathered at the University of the Free State (UFS) to celebrate the achievements of the Science-for-the-Future (S4F) Teacher Professional Development programmes as well as the successful collaboration between the UFS and other universities.  

The Science-for-the-Future unit in the Faculty of Education hosted a summit in the Centenary Complex on the Bloemfontein Campus on 30 September 2022. The Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, delivered the keynote address at the summit. Representatives from the South African National Roads Agency (SANRAL) – the official sponsors of the Science for the Future initiative – were also present, along with 300 teachers and representatives from the Department of Basic Education. 

In his welcoming address, Prof Patrick Mafora, Vice-Dean of the Faculty of Education, said the initiative exemplifies the UFS’ institutional goals, such as increasing our contribution to local, regional, and global knowledge.  It also supports development and social justice through engaged scholarship.

Improving the quality of teaching and learning for Math and Science 

Dr Cobus van Breda, Programme Director of S4F and Project Manager of the Universities Collaboration initiative, provided background regarding the programmes and stated that “… we know from research that there are many factors that prevent learners in rural areas from excelling in Mathematics and Science. These include subject content knowledge, lack of teaching resources at school and at home, along with a lack of parental involvement, among others.” He said the project aims to address the challenges related to Mathematics and Science teaching and learning in the country. One of the ways in which this goal can be accomplished, is by empowering teachers and learners with the necessary tools, including resources and knowledge, to create a successful learning space for Mathematics and Science. “Our mission is the advancement of innovative and effective Mathematics and Science teaching and learning,” he indicated.

Representatives from the DBE and other institutions were also given the opportunity to highlight the impact of the initiative in their respective institutions. “Our public schooling system, especially in poor and rural areas, is in crisis – more especially in the Eastern Cape. This is due to a lack of learning support and a lack of sufficient skills. This created a need for innovative, sustainable, and tactical solutions to improve the quality of teaching and learning for Math and Science. The Science for the Future initiative is exactly that,” explained Prof Jogy Alex from the Walter Sisulu University.

Making a difference and changing people’s lives 

During his keynote address, Prof Petersen indicated that he preferred the word ‘co-creation’ instead of ‘collaboration’, and he urged the “sponsors not only to contribute funding, but really contribute towards the intellectual project of this programme”. Surely, they have learnings and some ideas that can strengthen and expand the project, he said. Prof Petersen also alluded to the fact that SANRAL contributes towards a Research Chair in Science and Mathematics Education in the Faculty of Education, as well as the fact that, at the university, “we don’t exist to create knowledge for the sake of knowledge; we exist to create knowledge so that the knowledge can make an impact”. He referred to the project as an example of how knowledge is converted to practical application.  


Mr Adolph Tomes, Acting Business Operations Executive at SANRAL, also commended the initiative and its impact. “Although we as SANRAL are the funders and we get praise for being funders, this is a phenomenal project, and it is making a difference and changing people’s lives.”

New world-class Chemistry facilities at UFS
2011-11-22

 

A world-class research centre was introduced on Friday 18 November 2011 when the new Chemistry building on the Bloemfontein Campus of the University of the Free State (UFS) was officially opened.
The upgrading of the building, which has taken place over a period of five years, is the UFS’s largest single financial investment in a long time. The building itself has been renovated at a cost of R60 million and, together with the new equipment acquired, the total investment exceeds R110 million. The university has provided the major part of this, with valuable contributions from Sasol and the South African Research Foundation (NRF), which each contributed more than R20 million for different facets and projects.
The senior management of Sasol, NECSA (The South African Nuclear Energy Corporation), PETLabs Pharmaceuticals, and visitors from Sweden attended the opening.

Prof. Andreas Roodt, Head of the Department of Chemistry, states the department’s specialist research areas includes X-ray crystallography, electrochemistry, synthesis of new molecules, the development of new methods to determine rare elements, water purification, as well as the measurement of energy and temperatures responsible for phase changes in molecules, the development of agents to detect cancer and other defects in the body, and many more.

“We have top expertise in various fields, with some of the best equipment and currently competing with the best laboratories in the world. We have collaborative agreements with more than twenty national and international chemistry research groups of note.

“Currently we are providing inputs about technical aspects of the acid mine water in Johannesburg and vicinity, as well as the fracking in the Karoo in order to release shale gas.”

New equipment installed during the upgrading action comprises:

  • X-ray diffractometers (R5 million) for crystal research. Crystals with unknown compounds are researched on an X-ray diffractometer, which determines the distances in angstroms (1 angstrom is a ten-billionth of a metre) and corners between atoms, as well as the arrangement of the atoms in the crystal, and the precise composition of the molecules in the crystal.
  • Differential scanning calorimeter (DSC) for thermographic analyses (R4 million). Heat transfer and the accompanying changes, as in volcanoes, and catalytic reactions for new motor petrol are researched. Temperature changes, coupled with the phase switchover of fluid crystals (liquid crystals -watches, TV screens) of solid matter to fluids, are measured.
  • Nuclear-magnetic resonance (NMR: Bruker 600 MHz; R12 million, one of the most advanced systems in Africa). A NMR apparatus is closely linked with the apparatus for magnetic resonance imaging, which is commonly used in hospitals. NMR is also used to determine the structure of unknown compounds, as well as the purity of the sample. Important structural characteristics of molecules can also be identified, which is extremely important if this molecule is to be used as medication, as well as to predict any possible side effects of it.
  • High-performance Computing Centre (HPC, R5 million). The UFS’ HPC consists of approximately 900 computer cores (equal to 900 ordinary personal computers) encapsulated in one compact system handling calculations at a billion-datapoint level It is used to calculate the geometry and spatial arrangements, energy and characteristics of molecules. The bigger the molecule that is worked with, the more powerful the computers must be doing the calculations. Computing chemistry is particularly useful to calculate molecular characteristics in the absence of X-ray crystallographic or other structural information. Some reactions are so quick that the intermediary products cannot be characterised and computing chemistry is of invaluable value in that case.
  • Catalytic and high-pressure equipment (R6 million; some of the most advanced equipment in the world). The pressures reached (in comparison with those in car tyres) are in gases (100 times bigger) and in fluids (1 500 times) in order to study very special reactions. The research is undertaken, some of which are in collaboration with Sasol, to develop new petrol and petrol additives and add value to local chemicals.
  • Reaction speed equipment (Kinetics: R5 million; some of the most advanced equipment in the world). The tempo and reactions can be studied in the ultraviolet, visible and infrared area at millisecond level; if combined with the NMR, up to a microsecond level (one millionth of a second.

Typical reactions are, for example, the human respiratory system, the absorption of agents in the brain, decomposition of nanomaterials and protein, acid and basis polymerisation reactions (shaping of water-bottle plastic) and many more.
