UFS collaborates with Wits UWC to present higher education PhD Conference

The higher education sector in Africa has seen dramatic shifts over the past few years, and has attracted renewed attention from global funders and national policy-makers. In turn, country-wide challenges of poverty, inequalities, and university histories and stratification in South Africa and elsewhere on the continent offer rich opportunities for critical, theoretically-informed research to investigate and understand the conditions of possibility for change nationally and comparatively.

In particular, three centres at universities in South Africa have decided to build an organic collaboration, starting with research by doctoral research fellows at these universities, who presented papers at a two-day conference. The conference was jointly organised and hosted under the umbrella of the SARCHi (South African Research Chairs Initiative) Chair in Higher Education and Human Development at the Bloemfontein Campus of University of the Free State (UFS). Two keynote addresses on significant issues in the sector were presented by Prof Stephanie Allais, Director of the Centre for Researching Education and Labour (REAL, University of the Witwatersrand) and Prof Patricio Langa, Associate Professor of Sociology and Higher Education Studies at the Institute for Post-School Studies (IPPS, University of the Western Cape).

HE researchers collaborate
This ongoing collaboration between the three universities was initiated by Prof Melanie Walker at the UFS, in partnership with Prof Allais and Prof Langa and their institutions, with each institution taking a turn to host similar conferences. The conference at the UFS not only brought together doctoral researchers from these three centres to share their research, but it also offered the opportunity to engage with other early-career and experienced scholars. 

The conference was themed Critical Higher Education Studies: Theories and Research and aimed to build research relationships and stimulate debate among scholars. It was jointly organised by postdoctoral fellows: Ntimi Mtawa and Faith Mkwananzi (UFS), Bothwell Manyonga (Wits), and Patrick Swanzy (UWC).

Significant benefits for conference-goers and presenters alike

Conference-goers, as well as the presenters, reported great benefits as a result of their attendance and participation in the event. The research papers were important and central. However, the broader value of the conference was the platform it offered to young, emerging scholars to showcase their research projects, receive critical comments, listen and learn from one another, in addition to engaging with experienced scholars. 

Secondly, the variety of PhD research fellows who presented their research further enhanced critical academic engagement and the exchange of ideas. Presenters reported that the quality of feedback and comments on their projects had especially enhanced their current work. The focus of the stimulating keynote addresses also challenged participants to think well and critically about the field of higher education. Practical skills development also featured on the programme in the form of learning how to present a TED-style talk.

“The conference was especially valuable in bringing together early-career researchers working on critical and theorised approaches to higher education,” said Prof Walker. She added, “In particular, I valued the diversity of both the projects and their theoretical frames, which proved especially rich, together with the outstanding keynote contributions—one from political economy and one from sociology—which shaped the event as a whole.”

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.
