New member of the Pontifical Academy of Social Sciences - Prof Pearl Sithole

Social scientist and Vice-Principal: Academic and Research on the Qwaqwa Campus, Prof Pearl Sithole, was appointed by Pope Francis as a member of the Pontifical Academy of Social Sciences for her stellar work in social sciences. 
Academicians are appointed by the Pope on the basis of their competencies in the social sciences and their moral integrity.

Prof Sithole said she was looking forward to sharing meaning and impact with the world through a space dedicated to the social sciences. “It’s a great honour. I’m feeling really humbled. The social sciences and humanities are a hugely necessary space to make meaning of the world, but for some reason, in the pecking order, they were relegated to a space that is thought of last. This appointment is to a dedicated space – to say, let’s look at issues through that lens.”
The Pontifical Academy of Social Sciences was established by Pope John Paul II in 1994 with the aim of promoting the study and progress of the social sciences, primarily economics, sociology, law, and political science. To achieve its aims, the academy organises conferences and workshops on specific themes, promotes scientific surveys and research, and publishes publications. 

Prof Sithole said the academy provides a wonderful way of reminding academicians of the importance of relating science to the real world. 

“What I like about it is that it demystifies science. It says, be excellent in your field but be able to converse for impact, be able to come to a forum that worries about specific issues, it still encourages publications and pure science/scientific endeavours, advancements in their field, but sometimes people come together to look at an issue from various angles. For me, it’s such a wonderful way of saying we must remember that we are doing science in order to relate to the world, not just to understand for the sake of understanding,” she said.

Make a genuine effort to make a difference in whatever you do, and your work will speak for itself.- Prof Pearl Sithole. 

The appointment also coincides with Women’s Month, and Prof Sithole said she takes great pride in her womanhood. 

“I am a mother and a daughter. I strive to pinpoint problems and offer solutions. I am a social scientist. I’ve made it a mission to study how systems affect people by infusing humanity within the systems. Women have been made to be apologetic about the qualities that define us as women, which we bring especially into leadership. I don’t apologise for my emotions. I don’t apologise for my multitasking abilities; however, I do feel that women are often abused for having these.”

What would you say makes you a UFS woman of quality, impact, and care?

I am the sort of person who strongly believes that your work should speak for itself. I don’t work for accolades. My approach to life is to work genuinely to make a difference, and your work will speak for itself. If you wake up every day to genuinely make a difference, it is enough. You get a lot of satisfaction in life, and you sleep better because you know you have given it your best, and you know that sometimes you can actually see it making a difference.

What advice would you give to the 15-year-old you?

I would say, be true to yourself. At a younger age, you want to chase all sorts of aspirations that look glamorous, which is not a bad thing, because you have to have appetite; but in your appetite for excellence and as someone who lives for a purpose, be true to yourself. Be able to design a life that aspires, but at the same time be adaptable to what you discover your strengths to be.

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.
