Prof Abdon Atangana
Prof Abdon Atangana is known for his work in developing a new fractional operator used to model real-world problems arising in the fields of science, technology, and engineering. He was recently awarded the TWAS Mohammad A. Hamdan Award by The World Academy of Sciences.
Prof Abdon Atangana, Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS), was awarded the TWAS Mohammad A. Hamdan Award by The World Academy of Sciences for the advancement of science in developing countries.

It is the first time that the TWAS Mohammad A. Hamdan Award was bestowed. According to a statement issued by TWAS, this award is given for outstanding mathematical work carried out by a scientist working and living in Africa or the Arab region. It states that the award can be given for work in pure mathematics, applied mathematics, probability, or statistics. Prof Atangana received the award for his contribution to fractal mathematics and partial differential equations.

Making a difference in society

He is known for his research in developing a new fractional operator, the Atangana-Baleanu operator, which is used to model real-world problems. With this operator, he not only describes the rate at which something will change, but also account for disrupting factors that will help to produce better projections.

His work can be applied to make complicated predictions in the fields of science, technology, and engineering. His models can, for instance, help to predict the spread of infectious diseases among people in a settlement, forecasting the number of people who will be infected each day, the number of people who will recover, and the number of people who will die.

Prof Atangana’s models can also help to advise people drilling for water by predicting how groundwater is flowing in a complex geological formation. These are only two examples of how his work can be applied to make a difference in society.

The award from TWAS is the third prestigious commendation he has received in the past month. He was recently named as one of the top 1% scientists on the global Clarivate Web of Science list. His name also appeared on a global list of leading scientists published by Stanford University in the United States. The list is the result of a study published in PLOS Biology, a peer-reviewed open-access journal.

World’s most accomplished scientists

Honours awarded by TWAS and its partners are among the most prestigious for research in the developing world. They recognise outstanding achievements and contributions to science and acknowledge the best work by scientists from the global South.

TWAS, founded in 1983 by a group of scientists under the leadership of Pakistani physicist and Nobel laureate, Abdus Salam, believes that developing nations – by growing strength in science and engineering – will be able to address challenges such as hunger, disease, and poverty, through their knowledge and skills.

TWAS is represented in 100 countries, and of the more than a thousand elected fellows, 14 are Nobel laureates. Eighty-four percent of these fellows are from developing nations. TWAS fellows are also some of the world’s most accomplished scientists.

Prof Hendrik Swart richly contributes to research of phosphors

Since his appointment as the South African Research Chairs Initiative (SARChI) Chair, there has been a sharp increase in the number of papers and publications by Prof Hendrik Swart, Senior Professor in the Department of Physics at the University of the Free State (UFS). From January this year, he has already published 78 articles. Some of the journals that has published his work, includes:

• Nanotechnology (impact of 3.67)
• Dalton Transactions (impact of 4.097)
• Sensors and Actuators B: Chemical (impact 3.84)

“My biggest success, however, is the powerful group of researchers we have built over the years. Staff, postdocs and students – without them it would have been impossible. I am therefore much indebted to my groups on both the Bloemfontein and Qwaqwa Campuses.

“The good apparatus we acquired via a sponsorship from the National Research Foundation and Sasol is also one of the main reasons for this. The financial support I get from the university’s research office is of course also a contributing factor,” he says.

For the past 20 years, Prof Swart has been conducting research on any substance that glows. “I only adjust the focus to fit in with current trends,” he says.

Prof Swart believes that his research will make a contribution to the fundamental knowledge about phosphors, as well as to the training of good students for the academic and industrial world on the outside. For the man on the street, his research translates into better, brighter lights that use less energy.

His more recent research focuses on the development of nano-phosphors for light-emitting diodes (LEDS) and organic light-emitting diodes (OLED).

Prof Swart has presented papers on his research not only nationally, but all over the world – including countries in Europe and the East. Some of the most recent papers presented by him and his colleagues/postgraduate students include:

• Applications of AES, XPS and TOF SIMS to phosphor materials at die 15th European Conference on Applications of Surface and Interface Analysis 2013 in Forte Village Resort, Sardinia, Italy.
• Luminescent properties of phosphor nano thin films at the first International Symposium on Nanoparticles/Nanomaterials and Applications in Caparica (Lisbon, Portugal), where he was an invited speaker.
• Role of surface and deep-level defects on the emission of nano metal oxides at the 2014 NanoAfrica international conference, Vanderbijlpark, South Africa, where he delivered the keynote address.
• PHI systems and their modifications at KOVSIES at the PHI European User Meeting in Ismaning (Munich), Germany, where he was invited to speak.

Prof Swart also delivered the keynote address at the SETCOR International Conference on Smart Materials and Surfaces in Bangkok, Thailand. His lecture was titled, ‘Role of surface and deep-level defects on the emission and degradation of phosphor materials’.
