UFS student thrives in exchange programme with the University of Debrecen

As part of an exchange initiative facilitated by the Erasmus+ Mobility Programme, Jeremiah Hlahla, a student at the University of the Free State (UFS), is nearing the completion of his PhD studies at the University of Debrecen in Hungary. Hlahla’s journey, which began in February 2024 and is set to conclude in July 2024, has been a remarkable learning opportunity. “As a first time-traveller to Europe, I have thoroughly enjoyed engaging with people from different countries and cultures,” he said.

The benefits of international collaboration

Hlahla is currently pursuing a PhD in Botany, focusing on plant stress physiology. “My current PhD project investigates the physiological, biochemical and morphological responses of vegetable-type soybean, or edamame, to combined drought and heat stress,’’ he explained. He considers the University of Debrecen the ideal institution to complete his research due to its extensive expertise and resources in similar projects. He noted that his colleagues at Debrecen conduct significant work on plant protection against biotic and abiotic stresses, including salt and drought stress, as well as proteins and amino acids in barley and other legumes.

Given the vast knowledge available on similar projects, Hlahla has found substantial engagement with his work at the University of Debrecen. “Upon arrival, I delivered an introductory lecture presenting my UFS project on the synergistic effects of combined drought and heat stress on the physiology and biochemistry of edamame. It was an engaging session as everyone could relate to my work and asked many questions,’’ he said.

Insights gained from the exchange

Hlahla has also gained valuable lessons that will assist him in his research career, including biotechnology and physiology tools. “I learned how to prepare samples and use high-performance liquid chromatography (HPLC) and reversed-phase ultra-high-performance liquid chromatography (UHPLC) to quantify proteins and amino acids,’’ he said. These techniques are beneficial not only for his current work but will also support future soybean research.

As his experience at the University of Debrecen nears its end, Hlahla reflects on the collaborations and friendships he has formed, which stand out as a significant highlight.

UFS involved in project to light up the townships

2006-06-06

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.
