Prof André Roodt — Prof Andreas Roodt was recently awarded the MT Steyn Prize for Natural Science and Technology Excellence from the SA Akademie vir Wetenskap en Kuns. He will receive the prize, sponsored by Sanlam, at a function scheduled for September this year.

Prof Andreas Roodt, former Head of the Department of Chemistry at the University of the Free State (UFS) and retired Distinguished Professor in the same department, was recently awarded the MT Steyn Prize for Natural Science and Technology Excellence from the SA Akademie vir Wetenskap en Kuns.

The prize, a major recognition of his life's work, was presented to him for his contribution to the exploration and sustained development of natural science and technology and the successful application thereof in broader society.

Impacting society

About receiving the prize, he says it was a big surprise, but he is very proud to be honoured with this special award, “being an Afrikaans kid from a ‘platteland’ school outside Bloemfontein.”

Prof Roodt’s research focuses on understanding the reaction mechanisms of mainly inorganic coordination chemical systems that are critical to different industrial, medical, environmental, and metal beneficiation processes.

His research, for instance, contributes to important compounds and processes relevant to nuclear medicine and potential cancer therapy. Not so long ago, he registered a patent on this in Europe, Japan, and the USA that could help to diagnose and potentially treat cancer-related tumours in the future.

In addition, he continues to work on several projects aimed at developing cleaner industrial processes in the South African petrochemical industry. He is also focusing on more efficient ways of accessing the country’s mineral resources.

Career highlights

Throughout his academic career, Prof Roodt has achieved many significant milestones. He was extensively involved in crystallography for more than 30 years. One of his career highlights was being elected as the President of the European Crystallographic Association from 2012 to 2015, an organisation with more than 35 member countries.

In this field, he established an X-ray crystallographic facility in the UFS Department of Chemistry, which was officially named the ‘Roodt XRD Lab’ at the end of 2021.

He also sees his journey with the diverse group of 41 PhD and 54 MSc students (Afrikaans, English, Sesotho, Setswana, and isiXhosa) as another notable achievement in his career.

Other outstanding moments in Prof Roodt's career were his collaborations with research leaders from countries such as the USA, UK, Switzerland, Italy, Sweden, France, Croatia, India, Japan, Russia, the Netherlands, Germany, and Tunisia. These collaborations have allowed him to be recognised by peers worldwide and have demonstrated that Africa and South Africa can produce high-quality and relevant research that can compete on an international level.

The future

Despite his appointment as a Distinguished Professor and his commitment to finishing uncompleted work and assisting younger colleagues both in South Africa and abroad, Prof Roodt retired more than a year ago. He is now enjoying his retirement with his wife, children, and grandchildren, while also devoting time to his passion for collecting aloe plants and generating new hybrids.

UFS involved in project to light up the townships

The parties involved with the project are from the left: Prof Hendrik Swart (Departmental Chairperson of the UFS Department of Physics), Dr Thembela Hillie (CSIR), Prof Neerich Revaprasadu (Department of Chemistry at the University of Zululand) and Dr Wynand Steyn (CSIR).

UFS involved in project that could light up the townships

The University of the Free State’s (UFS) Department of Physics is involved with a project that could make life easier in the townships through the use of artificial light.

“The project is based on the use of sunlight to activate nano material in for example cement and paint during the day. At night the cement or paint can then radiate light,” said Prof Hendrik Swart, Departmental Chairperson of the UFS Department of Physics.

According to Prof Swart an amount of R3,9 million has been made available by the Council for Scientific and Industrial Research (CSIR) for the further development of the project.

Prof Swart visited the University of Florida in America in 1995 for a year where he researched luminescent phosphor material that is suitable for flat panel television screens. The red, green and blue spots on the television screens originate from these kinds of phosphor materials. “At that stage plasma television screens were only a dream. Today it is sold everywhere,” said Prof Swart.

“Upon my return I started a research group at the UFS which investigated the degrading of phosphor material. We also started to concentrate on the effectiveness of nano phosphors. In the mean time our cooperation with the Americans was strengthened with follow-up visits to America of my colleagues, Prof Koos Terblans and Mr Martin Ntwaeaborwa,” said Prof Swart.

“Nano phosphors are basically luminescent powders that consist of particles that are 1 millionth of a millimetre. These particles can provide light as soon as they are illuminated with, for instance, sunlight. The amount of time these particles can provide light, is determined by the impurities in the material,” said Prof Swart.

According to Prof Swart nano particles are developed and linked to infrastructure materials in order for these materials to be excited during the day by sunlight and then it emits light during night time.

“The nano material is of such a nature that it can be mixed with materials, such as paint or cement. The yellow lines of roads can for example emit light in a natural way during night time,” said Prof Swart.

About a year ago Prof Swart and Dr Thembela Hillie, a former Ph D-student of the UFS Department of Physics, had discussions with Prof Neerich Revaprasadu from the University of Zululand and the CSIR about the possibility of mixing these nano phosphor particles with other materials that can be used as light sources in the building of roads and houses.

“Prof Revaprasadu is also actively involved in the research of nano materials. Our efforts resulted in the CSIR approving the further extension of the project,” said Prof Swart.

“The UFS and the University of Zululand are currently busy investigating ways to extend the light emitting time,” said Prof Swart.

“There are eight M Sc and Ph D-students from the UFS and about five students from the University of Zululand working on this research project. The Department of Physics at the Qwaqwa Campus of the UFS, with Francis Dejene as subject head, is also involved with the project,” said Prof Swart.

According to Prof Swart the further applications of nano materials are unlimited. “Children whose parents cannot afford electricity can for instance leave any object such as a lamp, that is covered with these phosphor particles, in the sun during the day and use it at night as a light for study purposes,” said Prof Swart.

According to Prof Swart the further extension of the project will take about two years. “During this time we want to determine how the effectiveness of the phosphors can be increased. Discussions with the government and other role players for the possible implementation of the project are also part of our planning,” said Prof Swart.
