Interdisciplinarity in Action


Lunchtime learning webinar on


The  Intersection between Science and Visual Arts


In this webinar, Prof Willem Boshoff and Prof Louis Scott, both from the University of the Free State, will discuss the intersection between science and the visual arts. The webinar will explore how new levels of understanding may emerge when seemingly unrelated fields of interest intersect, supported by the ideas we may find in the endless diversity of nature.

This webinar is part of a series of three webinars on Interdisciplinarity presented from November to December 2020 via Microsoft Teams for a duration of 45 minutes each. The webinar topics in the series explore the intersection between Neuroscience and Music, between Science and Entrepreneurship, and between Science and Visual Arts. 
 
Date: Tuesday 8 December 2020
Topic: The intersection between science and visual arts 
Time: 13:00-13:45 (SAST)
RSVP: Alicia Pienaar, pienaaran1@ufs.ac.za by 7 December 2020 
Platform: Microsoft Teams

Introduction and welcome
 
Prof Corli Witthuhn – Vice-Rector: Research at the University of the Free State 

Presenters

Prof Willem Boshoff
Willem Boshoff is a Senior Professor in Fine Arts at the University of the Free State. As a conceptual artist, he engages primarily with language. Notably, his works have included the writing of several themed dictionaries, most often made accessible to a broad audience in the form of large art installations. His broad interdisciplinary interests, including the fields of botany, music, and lexicography, have over the years led to the development of a digital research archive, which he recently donated to the University of the Free State.  Prof Boshoff’s work is exhibited extensively, both locally and abroad, and has been included in major private collections and museums. Recently, he became the first South African artist to be awarded an A2 rating by the National Research Foundation (NRF). 

Prof Louis Scott
Prof Louis Scott is a retired professor and mentor in the Department of Plant Sciences at the UFS, with an interest in visual arts. He studies fossil pollen in natural lake, cave, swamp, and fossil dung deposits. He attempts to reconstruct our heritage associated with African prehistory through environmental history, including natural long-term processes of change. Prof Scott is widely published in this field, serves on the editorial boards of international journals, and has a B-rating with the National Research Foundation.

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.
