Monique Tangah (Economic and Management Sciences Faculty) won the PhD category of UFS Institutional Three-Minute Thesis competition hosted by the Postgraduate School.

Monique Tangah, a postgraduate student from the Faculty of Economic and Management Sciences at the University of the Free State (UFS), will represent the university on 13 November 2020 at the National Three-Minute Thesis, also known as the ‘3MT’, competition after she won the UFS competition. 

The UFS Postgraduate School hosted its Institutional 3MT on 9 October 2020 and winners chosen from each faculty competed against each other for the UFS Three-Minute Thesis title. Tangah, with her thesis titled, Cameroonian women’s empowerment through higher education: An African-feminist and Capability Approach Analysis, emerged victorious from a total of 20 students who are registered for their PhD and master's degrees. Tensions were high as the participants brought their research products of a very high standard forward in the virtual competition.

Willard Morgan, a student in the Faculty of Education, won the category for the Master’s Degree students with his title, Ideological representations of entrepreneurship in high school economic and management sciences textbooks.

The Three-Minute Thesis competition is an annual competition held at 200 universities across the world. It is open to PhD and master's students and challenges participants to present their research in just 180 seconds – in a way that is understood by an audience with no background in their specific research area.

Universities need to focus on the generation of new knowledge to solve critical problems in the country, continent and globally. The Three-Minute Thesis competition aims to achieve this by encouraging the increase of research output produced by master’s and PhD students. 


Winners and runners-up of the UFS competition for 2020 are:

For the PhD category
Winner: Monique Tangah (Economic and Management Sciences Faculty)
1st runner-up: Tamson Foster (Natural and Agricultural Sciences Faculty)
2nd runner-up: Monique Basson (Humanities)

For the Master’s category
Winner: Willard Morgan (Education)
1st runner-up: Kyla Dooley (Natural and Agricultural Sciences Faculty)
2nd runner-up: Bonolo Makhalemele (Natural and Agricultural Sciences Faculty)

The National Three-Minute thesis will be hosted virtually on 13 November 2020. PhD finalists from South African universities will compete for the 3MT SA title. Whose research thesis will stand the test of time? Join to find out.

Date: 13 November 2020
Time: 10:00-13:00

UFS researcher engineers metal surfaces
2015-03-03

Shaun Cronjé, a PhD student, in a surface characterisation laboratory at the UFS.

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
