Prof Hendrik Swart
Prof Hendrik Swart’s prolific publication record, the high impact of his work, and the outstanding quality of his scholarly contributions have placed him among the top 0,05% of all scholars worldwide.

ScholarGPS awarded Prof Hendrik Swart, Senior Professor in the Department of Physics at the University of the Free State (UFS), Highly Ranked Scholar status.

ScholarGPS celebrates Highly Ranked Scholars™ for their performance in various fields, disciplines, and specialties. Prof Swart’s prolific publication record, the high impact of his work, and the outstanding quality of his scholarly contributions have placed him among the top 0,05% of all scholars worldwide.

Prof Swart received Highly Ranked Scholar status (Lifetime) for ranking 16th in the discipline of Phosphor. Highly Ranked Scholars™ – Lifetime refers to distinguished authors, including those who are currently active, retired, or deceased. These scholars are recognised for their exceptional lifetime scholarly contributions, placing them in the top 0,05% of all scholars. Their achievements are evaluated across four categories: overall (across all fields), within their specific field of study, within their particular discipline, and across all specialties they are associated with.

Additionally, Prof Swart received Highly Ranked Scholar status (prior five years) for ranking first in Condensed Matter Physics, 42nd in Physics, 155th in Sensor, 207th in Physical Science and Mathematics, and 969th in all fields.

Scientific profile and credibility

ScholarGPS is a California-based company that applies artificial intelligence, data mining, machine learning, and other data science techniques to its massive database of more than 200 million publications and 3 billion citations to rank more than 30 million scholars and 55 000 institutions worldwide. They categorise more than 200 million scholarly publications into specific academic specialties. These specialties are further organised into 177 disciplines and 14 overarching fields. As a result of this extensive classification effort, scholars who are considered highly ranked within their respective fields can now be identified with greater precision. This identification is done not only within each academic specialty, but also across disciplines and fields, providing a comprehensive view of scholarly achievement and expertise. This system allows for the identification of top scholars within various areas of academic research in a way that was not possible before.

Prof Swart, who is an NRF B1-rated researcher, currently also holds the SARChI Research Chair: Solid-state Luminescent and Advanced Materials (2023-2027). On receiving this award from ScholarGPS, he says it is always a privilege to be recognised as one of the top scholars in your specific field, especially at this late stage of his career.

Professionally, Prof Swart says this award may boost his scientific profile and credibility in the academic community, potentially leading to more collaborations and partnerships.

In the field of condensed matter physics, the impact of his work is specifically noteworthy in the study of defects and impurities within semiconductors, along with their practical applications in optoelectronic devices. Moreover, his significant contributions extend to understanding optical and electronic properties at the nanoscale, bearing implications for the development of semiconductor technology, including light-emitting diodes (LEDs), photovoltaic cells, and quantum dots.

Primarily focused on mentorship

He believes his successes in physics and advances in understanding the universe are the result of a combination of variables, including innovative research, collaboration and networking, mentorship, effective communication, persistence, and resilience. “I am primarily focused on mentorship, which is critical to developing the next generation of physicists and creating a supportive environment for learning and discovery, as well as conducting groundbreaking research and making novel discoveries that are critical to pushing the boundaries of physics. I am always searching for opportunities to collaborate with other scholars, both inside and outside my discipline, which will result in constructive exchange of ideas, interdisciplinary discoveries, and collective problem solving.”

An interest in groundwater resource management ignited the spark for a PhD research thesis by Dr Yolanda Kotzé, Affiliated Researcher in the Institute for Groundwater Studies (IGS) at the University of the Free State (UFS).

Her PhD research thesis titled, A Framework for Groundwater Use Authorisations as Part of Groundwater Governance in Water Scarce Areas within South Africa, was the result of her interest in groundwater resource management. Dr Kotzé identified the agricultural sector as one of the major water users, and a decision was made to conduct research within this sector.  

Research funded by Institute for Groundwater Studies
Groundwater is water found underground in cracks and spaces in soil, sand, and rocks. It is stored in, and moves slowly through geological formations of soil, sand, and rocks (aquifers). The National Department of Water and Sanitation was indirectly the client for this research. The research project was funded by the IGS. Given the current drought, effective groundwater resource management can be achieved within all sectors through sustainable abstraction and use without over-abstraction.

“Groundwater can be effectively managed
in the agricultural sector by sustainable use,
monitoring the quantity of groundwater use,
and measuring groundwater levels,”
said Dr Kotzé.

Research addresses improvement of groundwater management
Her promotor, mentor, teacher, and friend, the late Prof Gerrit van Tonder, introduced her to the field of Geohydrology, and especially to groundwater resource management. “With my research, I made a significant contribution to the improvement of groundwater governance and groundwater resource management, as well as to the handling of groundwater use authorisations for irrigation purposes in South Africa,” said Dr Kotzé. With this significant contribution, she attempts to address the phenomenon of poor groundwater allocation and groundwater resource management by means of a framework. The development of this framework has shown the value of action research in an attempt to find a solution to a problem. “Groundwater can be effectively managed in the agricultural sector by sustainable use, monitoring the quantity of groundwater use, and measuring groundwater levels,” said Dr Kotzé.

The methodology of the research consisted primarily of action research, which has a five-phase cyclical process. The research was Dr Kotzé’s application for a PhD in Geohydrology at the UFS in 2012. The research was completed in 2015.
