With climate change, resource scarcity, and environmental pollution among the most pressing challenges of our time, Prof Elizabeth (Lizette) Erasmus used her inaugural lecture on Wednesday, 20 August to show how chemistry can provide powerful, practical answers. In her lecture, Molecules of Change: Chemistry for a Better Tomorrow, she traced her journey from fundamental research to pioneering innovations that turn waste into value, protect ecosystems, and improve food security.

During her talk, Prof Erasmus – Researcher in the Department of Chemistry – recalled a moment in 2018 that reshaped her career trajectory. While preparing a Sasol research grant on copper oxide nanoparticles, an entrepreneur assisting with the proposal posed a deceptively simple challenge: “So what?” “Although upsetting at first, those two words completely reshaped my outlook,” she explained. “They inspired my journey from purely academic chemistry towards more applied, impactful research – with the mission of not only advancing science, but of also improving society and the environment.”

 

From fundamental science to global solutions

Prof Erasmus began her career in organometallic chemistry, preparing and characterising complex molecules to understand their reactivity and physical properties. Later, her focus shifted to heterogeneous catalysis, where she explored nanomaterials and surface chemistry.

Her research has since evolved towards developing sustainable technologies that address urgent global challenges. One example is agricultural innovation: using green solvents to extract cellulose from wattle tree bark to create biodegradable superabsorbent polymers. “Unlike the polyacrylates in baby diapers, these SAPs degrade into nutrients for soil microbes and plants,” she explained. “By loading them with fertiliser, we develop slow-release, water-retaining materials that improve agricultural sustainability.”

Other projects include producing biochar to restore degraded soils, creating natural growth enhancers such as wood vinegar, and designing an ‘ultimate fertiliser’ that combines these products for long-term soil health. Her group also works on environmental remediation, developing hydrophobic sponges to absorb oil spills, repurposing building waste to clean polluted water, and using innovative chemistry to convert carbon dioxide into valuable products.

“We are even looking at one of the fastest-growing waste streams: e-waste,” Prof Erasmus noted. “With more gold per ton than natural ore, e-waste represents both a challenge and an opportunity. By developing porous absorbent materials, we can selectively capture and reduce gold ions directly to metallic gold – recovering a precious resource from waste.”

She concluded by crediting her team and collaborators: “This, however, is only the tip of the iceberg. The bulk of the work lies beneath the surface, carried out by dedicated students, collaborators, mentors, colleagues, friends, and family. I owe them my deepest gratitude, for they are the ones who truly sustain this journey of transforming chemistry into solutions for a better world.”

 

About Prof Erasmus

Prof Elizabeth (Lizette) Erasmus obtained all her degrees at the University of the Free State: a BSc (2001), BSc Honours in Chemistry (2002), MSc in Chemistry (2003), and a PhD in Chemistry (2005). She has published more than 80 research papers, holds an H-index of 21, and has extensive experience in supervising MSc and PhD students.

After serving as a senior researcher at the CSIR, she returned to academia at the UFS, where her international collaborations in the Netherlands and at UC Davis broadened her focus from organometallic chemistry to heterogeneous catalysis and nanochemistry. Her expertise spans organometallic chemistry, electrochemistry, surface characterisation, and nanomaterials.

New multi-purpose residences open in January 2015
2014-06-18

The UFS is currently busy with exciting new accommodation developments on both the Bloemfontein and Qwaqwa Campuses.

This includes a new residence with a hotel and a conference/lecture hall on the western part of the Bloemfontein Campus and the building of another residence on the Qwaqwa Campus.

“We have done what was possible in our quest to maximise the number of beds available in the older residences on the Bloemfontein Campus,” says Quintin Koetaan, Senior Director: Housing and Residence Affairs at the UFS. “This we achieved by converting underutilised and unutilised dining halls and kitchens into bedrooms, which was totally insufficient to address the dire need for beds.”

“The new residence building will have different types of accommodation. I am very excited and look forward to the completion of this project. And this particular residence also brings a very exciting architectural design to the university environment.”

The residence, with multiple blocks for different accommodation, will be wheelchair friendly and numbering and signage will also be in braille. This futuristic-designed building will stand the test of time and will be provide student accommodation until 2030.The R60 million project is funded by the UFS and the Department of Higher Education and Training.

In step with international university accommodation trends – as with Yale's residential college system – this residence will house female first-years who will be mentored by postgraduate students. Postgraduates will be headhunted with the support of the Student Representative Council’s (SRC) postgraduate committee. These postgraduate students will represent all the faculties. Block A and B will accommodate 184 female first-years.

Each floor in this residence will have a study room, two lounges, a kitchen and a laundry for 25 students. Security will be very tight, with three levels of security: entrance to residence, corridor and individual bedroom door. There will also be perimeter camera surveillance and a security officer outside and inside the residence. 

 
Block C will accommodate postgraduate students. The ground floor will house eight single-bed roomed flats. The first floor will have 16 single rooms sharing a bathroom, kitchen and living room, as well as one double room with its own bathroom. The second floor will have 21 single rooms sharing a bathroom, kitchen and living room.

Block D will house 18 hotel-like en suites, with a dining room where breakfast will be served. The target market here will be visiting academics and other university-affiliated visitors. Prices will be competitive to those of local guesthouses and hotels.

Bookings have already opened. Guests will be able to book in and access the hotel desk 24/7. The dining room, accommodating up to 60 people, will not only be open for hotel guests, but also for postgraduate students and UFS staff. Bookings will therefore be essential.

The expansion of bed spaces also took place at the Qwaqwa Campus. In 2012 a 200-bed residence with a state of the art computer room was completed. As a follow-up to this development, another 248-bed residence is now being built. In this particular residence, there will be designated post-graduate accommodation for 48 students.

The project will be handed over at the end of October 2014, with the first intake planned for January 2015.

Another development at the Qwaqwa Campus is the Chancellor’s House Bed & Breakfast. This B&B, with its 5 en suite rooms, is open for business for all UFS staff.
