Tebogo Motsei
Tebogo Motsei, a PhD student in Physics at the UFS, has been awarded the prestigious CV Raman International Fellowship for African Researchers.

Imagine a supercapacitor/battery made right here in South Africa that could change the way we store energy for the better. A product that can store energy in real time, thus solving energy problems as they happen, which makes a huge difference especially during power outages. A product that is not just good for the environment – transitioning away from lithium-ion batteries – but that can also create jobs and boost the local economy.

What we are talking about is a type of technology known as a sodium-ion supercapacitor/battery, which is the focus of Tebogo Motsei’s research. This technology serves as a power source for lighting, power plants, cars, and phones. Motsei, a PhD student in the Department of Physics on the Qwaqwa Campus of the University of the Free State (UFS), explains that – unlike lithium batteries, which have undergone extensive research and are expensive to produce – they are conducting experimental work and characterisations to determine if sodium-ion supercapacitor/batteries can perform as well or even better, using more affordable and eco-friendly materials.

“Our results, inspired by the urgent need for improved energy storage solutions in South Africa amid its energy challenges, have been very promising. We have successfully developed a sodium-ion supercapacitor/battery that stores as much energy as a lithium-ion battery. Moreover, it was crafted from recycled materials, making it a more cost-effective and environmentally friendly option,” states Motsei, adding that their battery is unique, as no one else in the world has created anything quite like it, despite numerous attempts.

She is also pleased with this supercapacitor/battery’s ability to repair itself. Motsei explains, “Imagine if your toy could fix itself whenever it got broken – that's kind of what our sodium-ion supercapacitor/battery does!”

Motsei is part of a group of scientists in the Department of Physics at the UFS who are working on this research and who have published a scientific article on their work, titled Composite super-capacitor/Na-ion battery with self-healing Fe–Cr alloy electrodes. 

“We're proud of what we have accomplished,” she remarks.

Fellowship: a dream come true

Being part of this impactful research contributed to Motsei receiving the prestigious CV Raman International Fellowship for African Researchers (2023). The fellowship is for African researchers engaged in research at an African institution, providing opportunities for research collaboration in India. Motsei will be the only candidate from South Africa.

This award is merit-based. Motsei attributes her selection to factors such as her strong academic record, research accomplishments, and innovative approach to solving complex problems. She also believes her experience in research, collaboration, and publication reflects her potential to make meaningful contributions to the field during the fellowship period. 

Another key factor contributing to her selection for this fellowship is her skill in fabricating actual devices/prototypes. “The hands-on nature of this research, allowing me to create devices from scratch, has always been my passion. Making my first device – the ‘Magnetron Sputtering Unit’ – during my master’s studies, was a turning point. It made me realise that I had made the best decision ever by choosing this research field. I'm truly passionate about my work,” says Motsei. 

For her PhD studies, she is supervised by Prof Richard Ocaya, Associate Professor in the Department of Physics, and co-supervised by Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics. Prof Ocaya, proud of Motsei’s achievements, believes that this fellowship not only serves as a great motivation for students – especially on the Qwaqwa Campus – but also highlights the global relevance of the UFS, particularly the Department of Physics.

Motsei says receiving this fellowship is a dream come true and a profound, life-changing moment for her. “I feel deeply honoured to be concluding this programme at the CSIR-Electrochemical Research Institute, the host institution in India, under the guidance of Prof Arul Manuel Stephan, whose invaluable assistance has been instrumental in my preparations.” Motsei also expressed her gratitude towards everyone who has supported her during this process, including Sudhir Kumar from the Indian Embassy in Pretoria.

“I am excited about how I can use this opportunity to make a difference. Whether it’s tackling significant global energy issues or finding new ways to solve everyday problems, I know this fellowship will give me the tools and support needed to make a real impact. Overall, I see this fellowship as a stepping stone to exciting new opportunities and adventures in the world of research,” she comments.

Making a meaningful impact

Motsei will be leaving for India on 23 February for a period of six months. She is excited about this new chapter in her research journey. “This fellowship will enhance my abilities as a scientist and leader in physics, providing me with essential skills, connections, and experience to make a meaningful impact in science and energy. I'm genuinely happy about this opportunity, which I thank God for.”

  • Sir Chandrasekhara Venkata Raman, after whom the fellowship is named, was a renowned Indian physicist who made great contributions to physics, winning many prizes and awards, including the 1930 Nobel Prize in Physics. He was known for his work in the field of light scattering and was the first Asian and non-European to receive a Nobel prize in any branch of science.

Centenary medals awarded
2004-10-15

Speech, Rector and Vice-Chancellor: Prof. Frederick Fourie

Op 28 Januarie 2004 het ons die honderdste herdenking van die geboorte van hier­die hoër onderwys instelling gevier met ‘n groot partytjie voor die Hoofgebou. Dit was ‘n wonderlike en vreugdevolle aand.

Die historiese prosessie tydens die amptelike opening van 6 Februarie 2004, in kleurvolle akademiese togas, vanaf ons wortels in Grey-Kollege tot by die Hoof­gebou, het die reistog vanaf die verlede na die hede treffend ge­simbo­liseer.

Talle ander eeufeesgeleenthede het gedurende hierdie jaar plaasgevind. Woensdagaand het ons die premiêre van ‘n dokumentêre film oor koning Moshoeshoe beleef – ‘n belangrike eeufeesprojek van die UV wat onder meer gemik is op die ontwikkeling van ‘ n gedeede geskiedenisbesef – a shared sense of history – and the celebration of a very special leadership, of a spirit of nation-building and reconciliation, in somebody like king Moshoeshoe (also MT Steyn and others…)

Last night we experienced a wonderful and moving honorary doctorary ceremony, with a wonderful group of South Africans like Khotso Mokhele, Antjie Krog, Jakes Gerwel, Van Zyl Slabbert, Jaap Steyn, Saleem Badat, and others - giving so much food for thought.

This evening, where we honour outstanding contributors to the development of this University, is a suitable moment to reflect on the course of the first 100 years of the University of the Free State.

1. ‘n Voëlvlug oor die geskiedenis: die vyf fases

1.1 Eerste fase: 1904 – 1927 (Eerste kwarteeu)

Eerste wankelende treë in die totstandkoming van die
Grey Universiteitskollege

Gedurende 1904 – 1920 word die eerste en mees basiese vakke in geestes- en natuurweten­skappe ingestel, eerste Senaat en eerste Raad saamgestel, en eerste geboue opgerig (hoofgebou en manskoshuis). Teen 1920 was daar egter slegs ongeveer 100 studente, die instelling was finansieel in die knyp, met geen vooruitgang en groei, en ook nie ‘n vaste rektor nie – klaar­blyk­lik was die GUK nog geen lewensvatbare instelling nie. Vrystaatse kinders word steeds eerder na ander universiteite gestuur.

Hierna maak ds JD Kestell, rektor 1920 – 1927, ‘n reuse bydrae om ‘n versukkelde, arm, klein universiteitskollege lewensvatbaat te kry. Hy slaag met fonds­insameling en oortuig Afrikaanse én Engelse ouers om hulle kinders na die GUK te stuur. Teen 1927, met 420 studente, word die eerste nederige mylpale van kritiese massa bereik te midde van ‘n steeds armoedige Vrystaat­se gemeenskap en ‘n studentekorps met gelapte klere. [Maar ook die tyd waarin die Reitz-saal, waarin hierdie plegtigheid plaasvind, gebou is.]

1.2 Second phase: 1927 – 1950 (Tweede kwarteeu)

The Grey University College becomes a fully fledged university

By 1950 the establishment of main basic and career-oriented faculties were completed – Faculty of Commerce in 1937; Faculty of Law as wel as the Faculty of Education in 1945. Student numbers reached 1000 in 1950.

Die UKOVS beleef en oorleef die Groot Depressie, die armblankevraagstuk, die Tweede Wêreldoorlog, taal- en politieke stryd onder Afrikaners, en die stryd van Nat vs Sap, ook op die kampus. Die tydperk word veral gestempel deur die taalstryd met DF Malherbe (rektor 1929 – 1934) as sterk kampvegter vir Afrikaans. Veral na 1948 volg rektor Van der Merwe Scholtz ‘n doelbewuste enkel­talige Afrikaanse rigting (Christelik-nasionaal).

1.3 Derde fase: 1950 – 1976 (Derde kwarteeu)

Ongekompliseerde groei ná onafhanklikheid

Hierdie periode word gestempel deur verkryging van onafhanklikheid as universiteit op 18 Maart 1950. Daarna beleef die UOVS onder rektore Scholtz, Flippie Groene­woud en Benedictus Kok stelselmatige groei sonder beduidende finansiële kommer. Die UV is duidelik ‘n Afrikaanse ‘volksuniversiteit’ op Christelik-nasionale grondslag, onlosmaaklik in­gebed in die dominante politieke bedeling van apartheid en afsonder­like ontwikke­ling. Dit is die hooggety van Afrikaner (en blanke) self­vertroue en heerskappy. Vir personeel sowel as studente is dit ‘n relatief onge­kom­­pliseerde tyd getipeer deur groeiende voor­spoed in die blanke en Afrikaanse gemeenskap, goeie werksvooruitsigte vir studente, kommer­lose studentepret, en min spanning op die kampus.

The academic focus is on teaching, especially to provide staff for the growing public service and education sectors. Research has a low profile. More career-oriented or professional faculties are established: agriculture in 1958 and the medical faculty in 1970. Student numbers reach 2000 in 1960, 4000 in 1970 en 7000 in 1975. Many new residences and academic buildings are erected, especially in the Kok-era.

Teen 1976 was die vernaamste boustene van ‘n medium-grootte universiteit in posisie: onafhanklikheid, genoeg fakulteite, genoeg koshuise en akademiese geboue, goeie sport en kultuur. Op die oog af is die ideaal van volwaardige, onaf­hanklike universiteit verwesenlik.

1.4 Vierde fase: 1976 – 1989

Op koers na die jaar 2000: van die statiese na vernuwing

Politieke onstabiliteit en oorgang in die land begin met die Soweto-onluste, die drie-kamer parlement, PW Botha se Rubicon-toespraak, noodtoestande, die ‘struggle’ en opkoms van UDF, en so meer. Die UOVS is swaar onder die indruk van die ‘totale aanslag’ en die regering se totale teen-strategie. Die Universiteit word polities en akade­mies geïsoleer en intellektueel gemarginaliseer. Ekonomies is dit moeiliker tye na die oliekrisis en die begin van hoë inflasie, en die Staat se finansies wat begin knyp.

Academically this period is distinguished by the strong stimulation and support of the research capacity and orientation by rector Wynand Mouton, which leads to a significant growth in research, especially in the natural sciences. The faculty of Theology is establishyed, the Sasol-UFS library erected. Student numbers continue to grow, but at a much slower rate then before.

Twee ander fasette kenmerk hierdie tydperk: eerstens die toelating van die eerste swart studente (nagraadse 1978, voorgraads 1988) en die begin van die era van multikulturaliteit; tweedens, die begin van subsidie- en finansiële probleme en die eerste rasionalisasie van personeel. Albei hierdie is voortekens van ingewikkelde jare wat sou volg vanaf 1990.

1.5 Fifth phase: 1990 – 2004: The turn of the century brings winds of change

(a) 1990 – 1996:

Die Francois Retief era word gedomineer deur die gevolge van die politieke verande­ringe deur president FW de Klerk en die vrylating van Nelson Mandela. Die UV ontwaak tot die realiteit van die oorgang na ‘n post-apartheid samelewing en komende ANC regering. Die eerste versigtige trans­for­ma­sie­stappe word ingestel, multikulturaliteit word die groot uitdaging, en die eerste fasiliterende strukture (bv. die Multikulturele Komitee) word gevestig. Die eerste senior swart personeel word aangestel.

The dramatic decision about the introduction of parallel-medium teaching in 1993 signals the start of multilingualism as well as a significant growth in the admission of black students. Total student numbers are stable at approximately 9000, but black student numbers grow to 36% in 1995. Initially the change to parallel-medium impact negatively on staff teaching load and hence onresearch outputs.

Die inkrimping in staatsubsidie lei tot ernstige finansiële probleme, besparings­pogings, grootskaalse rasionalisasie van personeel in veral die fakulteit Lettere en Wysbegeerte, spanning tussen Senaat en rektoraat oor finansies – en mismoedig­heid onder personeel.

(b) 1997 – 2004:

The time of rector Stef Coetzee and his successor is the era of the new democracy and transformation. At the beginning of this phase Afrikaans parents start sending their children to other Afrikaans universities; residence become half full. Tensions arise between student groups. This is followed by the large breakthroughs in student transformation in 1997, which normalises the situation. The University becomes a leader in transformation. This leads to the acceptance of the multicultural and multilingual character, on a Christian foundation, of the University. The name changes to the University of the Free State (UFS).

Met ‘n finansiële krisis en verdere rasionalisasie van personeel op hande word die akade­miese en finansiële ‘draaistrategie’ in Januarie 2000 geloods. ‘n Drama­tiese finansiële ommekeer lei tot herinvestering in kampus­fasiliteite en toerusting, ‘n toename in personeel en beduidende verhoging in vergoeding bokant inflasie. Terselfdertyd is daar ‘n opbloei in die akademie: innoverende onderrig­programme, e-leer, ‘n fokus op programgehalte. Konsolidering van fakulteite vind plaas, die Bestuurskool word gestig, daar is sterk internasio­na­lisering en groei in navorsing. Profes­sionele bemarking en strategiese kommunikasie verander die beeld van die UV.

Studentegetalle groei dramaties van 10 000 in 2000 na meer as
23 000 in 2003/4; groei moet nou beperk word. Afrikaanse studente keer terug; koshuise kry lang waglyste. Die verhou­ding tussen wit en swart studente op die hoofkampus is rondom 50:50.

The period ends with the incorporation of the Qwaqwa en Vista Bloemfontein campuses, the approval of a new language policy which also established multilingualism in management and administration, and purposeful efforts to consolidate the foundations of an institutional culture of multiculturalism, multilingualism, non-racialism and non-sexism – a culture of tolerance, embracement and justice in diversity. The Centenary is celebrated with harmony and prosperity on the campus in 2004 (although always with a good sprinkling of unexpected challenges and problems).

2. Vanaand bring ons hulde, en sê ons dankie aan, die bouers van die UV

Oor ‘n honderd jaar het honderde, duisende mense ‘n bydrae gelewer tot die UV se ontwikkeling.

Kom ons eer en dank diegene wat, 100 jaar gelede in a baie arm gemeen­skap wat bykans verwoes is deur die Anglo-Boere oorlog, nooit opgehou droom het oor ‘n eie universiteit om die jongmense te dien, om die mense te dien – die arm Vrystaatse mense van daardie tyd.

Let us honour and thank all those who painstaking built this university from very humble beginnings, from the first fragments and embrio of a university – through a hundred years of various wars, of the struggle, of poverty, of bad times but also good times.

In elke dekade, in elke een van die honderd jaar, is hierdie instelling gebou deur die harde werk, idealisme en verbintenis (“commitment”) van leiers, akademiese personeel, steundiens­personeel, dienswerkers. Laat ons hulle eer en dank.

Let us honour the spirit of commitment and ‘vasbyt’, of ‘never let go’, the determination to overcome obstacles, of timely and pre-emptive adjustment to new challenges and new needs, which made that possible.

Kom ons vier en eer die duisende studente wat in die 100 jaar hier was, wat die spesiale tradisies en spesiale gees geskep het van Kovsiekampus, van Kovsie studentelewe – en wat gedurig nuwe tradisies en gebruike geskep (en gepleeg) het, soos net studente dit kan doen.

Let us celebrate the way this University has, in the last 20 years, once again taken up the challenge of transformation and adjusting to new needs, serving all the people, especially those most in need at this time of our history – thereby closing the circle, going fully “from post Anglo-Boer War to Post-Apartheid”.

Kom ons vier, en wees innig dankbaar vir, die wyse waarop hierdie Universiteit in die laaste 5 jaar gedraai het, finansieel sowel as akademies, en die wonderlike periode van akademiese groei en ontwikkeling en verdieping waarin ons nou staan – tesame met die geleenthede wat QwaQwa en Vista Bfn vir ons bied. Hierdie voorspoed sien ons in die nuwe fisiese aangesig van die kampus, insluitend hierdie wonderlike Eeufeeskompleks.

Let us thank God, the Almighty, who has guided this university through a tumultuous century, for always being there for us, for blessing us in so many ways. In Deo Sapientiae Lux

So: vanaand is ons hier om erkenning te gee en dankie te sê…

Soveel mense het veel vroeër hul fondament-leggende bydraes gelewer, en alles wat ons vandag hier sien, moontlik gemaak. Selfs mense uit meer onlangse jare is reeds oorlede – enkeles terwyl hulle nog in diens van die UV was, ander na hul aftrede.

‘n Bepaalde groep was bevoorreg en geseend om in die laaste ongeveer 30 jaar by die UV betrokke te kon wees, én om vandag nog in die lewe te wees. Dit is van hulle wat vanaand hier is, en wat vanaand Eeufeesmedaljes ontvang.

Geweldige moeite is gedoen om hierdie proses van seleksie en keuring so billik en deeglik as moontlik te doen. Uiteraard is so ‘n proses nie volmaak nie en sal almal nie saamstem met die uitkomste van die proses nie. Groot moeite is egter gedoen in hierdie fase om mense nie verkeerdelik uit te laat uit of in te sluit in die toekenningslys nie, in volle bewustheid dat daar waarskynlik steeds foute gemaak sal word. Onvermydelik sal daar foute wees, of mense wat uitgelaat is. Ons vra daarvoor nederig om verskoning en begrip.

Billikheid, so ‘n belangrike rigsnoer vir hierdie Universiteit, veral in hierdie tye, lei ons ook dat ons oë oop is vir die bydraes vir mense uit alle afdelings van die Universiteit, wat lei tot ‘n bepaalde balans tussen fakulteite, tussen fakulteite en steundienste, tussen poskategorieë, tussen geslag en ras, en individue soveel as mense in spanverband.

In Deo Sapientiae Lux
