Physics excels in Afrikaans Academy for Science and Art symposium
UFS postgraduate students in the Department of Physics attended the Student Symposium of the Afrikaans Academy for Science and Art. From the left are Izak van der Westhuizen (PhD) and Hélène Szegedi (MSc), who both came in second place in their respective sessions. On the right of the banner are Dina Oosthuizen (PhD) and Lucas Erasmus (MSc),who claimed first place in their respective sessions.

Every year postgraduate students from all universities and universities of technology in the country are invited to participate in the student symposium of the Afrikaans Academy for Science and Art.

Honours, master's, and doctoral students from different universities in different scientific fields, including chemistry, physics, computer science, engineering, geography, medicine, etc. participated in the symposium. From the Department of Physics at the University of the Free State (UFS), Dina Oosthuizen (PhD) won a first prize in session 1, Hélène Szegedi (MSc) won second prize in session 2, where Lucas Erasmus (MSc) claimed first place and Izak van der Westhuizen (PhD) took second place in session 3.

'We love what we do'

Students from the UFS do incredibly well each year at this symposium. “These achievements speak of the excellent education and training we receive, especially in the department. Physics students not only have lecturers and supervisors who are well-respected in their own research fields but have access to world-class instruments in our physics laboratories. We also love what we do and see it as a privilege to share our work.

“The symposium is also an opportunity to gain valuable experience in presenting our own research as well as getting exposure to various research topics, methods and scientific disciplines,” said Hélène Szegedi, who is a junior lecturer in the Department of Physics

Symposium unique on many levels



Although every participant has to present in Afrikaans, it is not only Afrikaans-speaking students who participate in the symposium. Szegedi said: “The language requirement for the symposium does, however, create the opportunity to develop Afrikaans further as a science language, and we sometimes have to coin new words or terms to describe our research, making this symposium unique and beneficial on many levels.”

What do diamonds, chocolates, bugs and almost 30 Nobel Prizes have in common? Crystallography
2014-10-15

 

Some of the keynote speakers and chairpersons at the third world summit in the International Year of Crystallography (in Africa) were, from the left, front: Profs Abdelmalek Thalal (Morocco), Prosper Kanyankogote (University of Kinshasa, Democratic Republic of the Congo); Habib Bougzala (Tunisia), Santiago Garcia-Granda (IUCr, University Oviedo, Spain), Michele Zema (IYCr 2014, Italy/UK) and Dr Jean-Paul Ngome-Abiaga (UNESCO, Paris, France); back: Dr Thomas Auf der Heyde (Acting Director-general, South African Department of Science and Technology); Dr Petrie Steynberg (SASOL) and Prof André Roodt (UFS, host).

The third world summit in the International Year of Crystallography (in Africa) was hosted by Prof André Roodt, Head of the Department of Chemistry and President of the European Crystallographic Association,  at the University of the Free State in Bloemfontein.

A declaration with and appeal to support crystallography and science across Africa, was signed.

When one mentions 'Crystallography', or more simply 'crystals', what comes to mind? Diamonds? Perhaps jewellery in general? When thinking of crystals and Crystallography, you will need to think much bigger. And further – even to Mars and back.

Crystallography refers to the branch of science that is concerned with structure and properties of crystals. The obvious examples would include cut diamonds, gemstones such as amethysts, and ‘simple’ crystals such as selenite and quartz.

But have you thought about the irritating brown scales at the bottom of your kettle? The sand in your shoes? The salt over your lamb chops or the sugar in your coffee? All crystals. From egg shells to glucose, from bugs and insecticides to additives in food – even the compounds in chocolate – all fall under the close scrutiny of Crystallography.

The breakthroughs this field of science has produced have led to almost 30 Nobel Prizes over the years.

Determining the structure of DNA by crystallography was arguably one of the most significant scientific events of the 20th century. Different diseases have been cured or slowed by medicines obtained based on crystallographic studies. These include certain cancers, HIV/Aids, Tuberculosis and Malaria. Biological Crystallography enables the development of anti-viral drugs and vaccines.

This field of science influences our daily lives in virtually immeasurable ways. Here are but a few areas of study and development Crystallography contributes to:

•    LCD displays;
•    cellular smartphones;
•    insects and insecticides;
•    additives and products in foods;
•    improved effectiveness and security of credit cards;
•    new materials to preserve energy;
•    better gasoline with less by-products;
•    identify colour pigments used in paintings from the old masters, indicating if it’s an original or an imitation; and
•    beauty products such as nail polish, sun-block, mascara and eye shadow.

Crystallography is also currently used by the Curiosity Rover to analyse the substances and minerals on Mars.

Crystals and Crystallography form an integrated part of our daily lives – from bones and teeth to medicines and viruses, from chocolates to the blades in airplane turbines. Even down to the humble snowflake.
