Dr Francois Jacobs
Dr Francois Jacobs received his Doctor of Philosophy degree in Chemistry on Monday, 9 December.

Dr Francois Jacobs, a 30-year-old PhD graduate, has recently returned from an intensive training workshop in Harwell, Oxford, courtesy of the David Blow Bursary. This prestigious award recognises outstanding African researchers making significant contributions to macromolecular crystallography.

Dr Jacobs earned his Doctor of Philosophy degree in Chemistry on Monday, 9 December. While earning a PhD by the age of 30 was not part of his initial plan, he always aspired to pursue higher education. “From a young age, I had a strong desire to study at university. Once I got there, my ambition shifted towards obtaining a PhD,” he says, reflecting on the journey that led to this remarkable achievement.

Groundbreaking research on cancer and antibiotics

Dr Jacobs’ research addresses some of the most pressing health challenges of our time: cancer and antibiotic resistance. Using crystallography, he investigates the interactions between newly developed anticancer and antibacterial compounds and biological structures such as proteins at the atomic level. This work is vital in combating the growing threat of antibiotic-resistant bacterial infections and advancing cancer treatments.

"For me, it's about seeing humans thrive and reducing the suffering caused by illness," he explains. "I lost my grandmother to cancer, and I hope my work can spare someone else’s loved one from a similar loss."

Prestigious workshop with global experts

The "DLS-CCP4 Data Collection and Structure Solution Workshop," hosted by Diamond Light Source, offered Dr Jacobs an unparalleled opportunity to learn from leading experts in macromolecular crystallography. The workshop covered critical skills such as growing protein and DNA crystals, preventing degradation during data collection, and processing complex data. Participants also gained insights directly from the engineers and scientists behind the facility’s cutting-edge software and synchrotron technology.

“It was an incredible opportunity to learn from some of the brightest minds in the field,” says Dr Jacobs. “Not only did I acquire new skills, but I also forged new collaborations with potential research partners who can help take my work to the next level.”

The David Blow Bursary, which enabled Dr Jacobs to attend this workshop, is awarded to  African researchers conducting impactful macromolecular crystallography studies.

"This training has been transformative," he adds. "It is a fantastic experience for any aspiring researcher, and I’m grateful to have had the chance to learn from these experts. Many researchers who attend workshops like this go on to work at the Diamond Light Source itself. I am eager to see where this training will take me."

A vision for the future

As Dr Jacobs continues his research, he remains driven by the hope that his work will lead to life-saving advancements in healthcare. “I want my research to provide hope and solutions for individuals battling cancer and bacterial infections,” he says.

His achievements exemplify the transformative power of education, research, and collaboration, and his story serves as an inspiration to aspiring researchers across Africa.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
