Architectural excellence celebrated at recent Sophia Gray lecture
Prof ‘Ora Joubert, a leading architect and academic, delivered the 30th Sophia Gray Memorial Lecture at the UFS.
A jolly kink, creative, aesthetically sensible, a dream house, welcoming, true colours, bright lights – these are some of the terms one can use to describe the work of Prof ‘Ora Joubert, leading architect, academic and former head of the UFS Department of Architecture.

A journey through time and space

She is also the 30th laureate to deliver the recent Sophia Gray Memorial Lecture on the Bloemfontein Campus of the University of the Free State (UFS). The lecture was titled: La Promenade Architecturale – A journey through time and space. “The title refers to the revelatory experience of an observer who wanders on a pathway in and through architectural spaces,” said Jan Ras, lecturer in the Department of Architecture and organiser of the event. 
“As the observer tours the architectural configuration, a sequence of composed images, themes and ordering systems are revealed. This gradually unfolds as the observer moves through the spaces,” Ras said.

The lecture, which coincided with an exhibition at the Oliewenhuis Art Museum, is a highlight of the South African architectural community and celebrates outstanding practitioners and academics in architecture.

Besides the numerous design awards she received as practitioner, Prof Joubert’s work has also received critical acclaim internationally in publications from Australia, to Russia and the UK. In 2001 she was cited as one of the most esteemed architects under the age of 40 and her work was included in the 2004 Phaidon Atlas of Contemporary Architecture. She is also a well-respected academic with 34 articles published in a variety of publications.

Recognising the intelligence and ingenuity of design

Prior to the lecture, the department also presented a mini-congress, introducing the new PhD with Design programme. This programme recognises the intelligence and ingenuity of design and is aimed at, among others, younger MArch graduates who wish to explore creative research. The department envisaged that the PhD study might be practice-based for architects who wish to document and research their own work and or design-led for candidates who wish to explore a new creative project. 

Forming part of this week filled with architectural creativity was a fundraising breakfast, with contributions going to the Sophia Gray Bursary Fund. The fund is part of a greater call to alumni and friends to be actively involved in the department’s continuous development and future endeavours towards imagination, care and excellence.

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.
