Chemistry changing the world to create a better future
These practical applications of Chemistry are part of the relevant and practically applicable research Prof André Roodt (far left) and his research group are involved in. With him are Dr Ebrahiem Botha, Post-doctoral fellow; Pheelo Nkoe, PhD student; Shaun Redgard, MSc student; and Dr Orbett Alexander, Post-doctoral fellow

Some people have a gift for explaining the most complex concepts in a way anyone could understand. Combine this gift with passion, energy, and enthusiasm, and you are close to describing a meeting with Prof André Roodt

Prof Roodt not only teaches Chemistry, he lives it. He has published more than 320 papers, lectured internationally more than 100 times, and has guided 35 PhD and 48 MSc students to complete their degrees. These figures are likely to conjure up visions of a dusty academic working on pie-in-the-sky theories. 

Adding value

Within minutes you are made aware of the fact that Chemistry is not only a subject confined to classrooms and labs. It is a means of changing the world through research to create a better future. In academic terms, Prof Roodt and his team are involved in ‘Homegeneous Catalysis’, ‘Radiopharmacy: Theranostics’, ‘Metal Benefication’, and ‘Conversion of carbon dioxide and water’. And just when you start to remember how terrifying high-school Chemistry was, Prof Roodt explains the practical nature of what they are doing.

Few of us are aware of the exact processes that produce fuel for our cars, although we probably know that these processes have side effects which are usually detrimental to the environment; but what if the by-products of these processes can be turned into speciality chemicals which could add value in different ways?

Ever wondered how medication know where to go in your body? Well – just imagine highly specialised (clever) pharmaceutical agents giving off their own ‘light’, knowing exactly where to go, showing you where they are going, and knowing what to do in order to provide information and interact with specific cells in your body to assist in healing cells and fighting disease. Exciting.

Passionate people

But, as they say in the ads, that is not all; imagine better ways to generate power, using the natural processes in plants to increase natural oxygen where needed, and to be able to change oxygen levels in the environment.

These practical applications of Chemistry are part of the relevant and practically applicable research Prof Roodt and his research group are involved in.

When you leave Prof Roodt’s office, you realise that this is what the UFS is all about: Global impact. World-class research. Passionate people. And seizing the opportunity to create the future.

Boyden Observatory turns 120

The Boyden Observatory, one of the oldest observatories in the Southern Hemisphere and a prominent beacon in Bloemfontein, recently celebrated its 120th year of existence.

This milestone was celebrated by staff, students, other dignitaries of the University of the Free State (UFS) and special guests at the observatory last week.

“The observatory provides the Free State with a unique scientific, educational and tourist facility. No other city in South Africa, and few in the world, has a public observatory with telescopes the size and quality of those at Boyden,” said Prof. Herman van Schalkwyk, Dean of the Faculty of Natural and Agricultural Sciences at the UFS.

The observatory, boasting the third-largest optical telescope in South Africa, has a long and illustrious history. It was established on a temporary site on Mount Harvard near the small town of Chosica, Peru in 1889. Later it was moved to Arequipa in Peru where important astronomical observations were made from 1891 to 1926. “However, due to unstable weather patterns and observing conditions, it was decided to move the Boyden Station to another site somewhere else in the Southern Hemisphere, maybe South Africa,” said Prof. Van Schalkwyk.

South Africa's excellent climatic conditions were fairly well known and in 1927 the instruments were shipped and the Boyden Station was set up next to Maselspoort near Bloemfontein. Observations began in September 1927 and in 1933 the new site was officially completed, including the 60 inch (1.5 m) telescope, which was then the largest optical telescope in the Southern Hemisphere. This telescope was recently refurbished to a modern research instrument.

The observatory has various other telescopes and one of them, the 13" refractor telescope, which was sent to Arequipa in 1891 and later to Bloemfontein, is still in an excellent condition. Another important telescope is the Watcher Robotic Telescope of the University College Dublin, which conducts many successful observations of gamma ray bursts.

“In the first few decades of the twentieth century, the Boyden Observatory contributed considerably to our understanding of the secrets of the universe at large. The period luminosity relationship of the Cepheid variable stars was, for example, discovered from observations obtained at Boyden. This relationship is one of the cornerstones of modern astrophysics. It is currently used to make estimates of the size and age of the universe from observations of the Hubble Space Telescope,” said Prof. Van Schalkwyk.

“The Boyden Observatory contributed to the university’s astrophysics research group being able to produce the first M.Sc. degrees associated with the National Space Science Programme (NASSAP) in the country and the Boyden Science Centre plays an important role in science and technology awareness of learners, teachers and the general public,” said Prof. Van Schalkwyk.

The Boyden Science Centre has also formed strong relationships with various institutions, including the South African Agency for the Advancement of Science and Technology (SAASTA) and the Department of Science and Technology. The centre has already conducted many different projects for the Department of Science and Technology, including National Science Week projects, as well as National Astronomy Month projects. It also serves as one of the hosts of SAASTA’s annual Astronomy Quiz.
