Crystal-Donna Roberts
Crystal-Donna Roberts is a multifaceted lady. She appears regularly in soaps and is now a published author too. Speurder Sammi, an Afrikaans book written for early teens, explores themes such as anxiety, trauma, and pain.

She loved mysteries from a young age. Growing up, Crystal- Donna Roberts was fond of Columbo and Murder she wrote. Roberts, who graduated with a BA Drama and Theatre Arts in 2005, says she had always liked the tricky puzzles Scooby-Doo and Nancy Drew had to solve. She eagerly joined them on their missions page by page. Being an actress and having a busy schedule in front of cameras, Roberts actively decided to put time aside last year to write while participating in the Jakes Gerwel mentorship programme for upcoming authors. A lifelong dream came true when she wrote her debut novel, Speurder Sammi: Die blou steen (Detective Sammi: The blue stone). Tafelberg published her mystery-based story, which Roberts launched in September.

“Sammi is a teenager who lives with her artist aunt Valerie. The duo went on holiday visiting Oumie and Dedda in the Northern Cape. Although Sammi will miss her friends, April and Lerato, she is looking forward to a change of scenery. It will also distract her mind from the anticipation of waiting for acceptance at an art school she fancies. However, rural towns are full of surprises – and chancers.”

“There are teenage memories we seldom forget. The memory of growing pains is still vivid in my mind. I recall it and draw inspiration from it.”

Roberts doesn’t have set rituals when she writes. “I allow myself to do what my body and soul likes. Sometimes this means simply sitting down and enjoying a cup of tea.” Looking back on her fellowship, she discovered her love for creating new worlds and allowing the story to develop a storyline of its own. “I’ve learned I still have a lot to learn – this excites me. I also learned the importance of deadlines, even though they are scary.”

The former UFS student says she chose the Northern Cape as the setting for her story as it is one of the most beautiful parts of our country. “It is one of the prettiest parts of our country. I wanted my character to explore new horizons, but to remain between her loved ones when she goes through her healing and strengthening process.” Although Roberts is determined to write her second book, the details are still unknown. In the meantime, she enjoys reading Walter Russel’s The Secret of Light. She draws inspiration from Andrew Davidson’s The Gargoyle. “Apart from the story that deeply resonates with me, I can appreciate the detail in the story and Davidson’s writing style.”

Presenter and television, theatre and film actress, Roberts is currently starring in kykNET’s drama series, Fraksie. She is also known for her roles in 7de Laan, Getroud Met Rugby, Montana, Vallei van Sluiers, Krotoa, and The Endless River.

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.
