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.

UFS Odeion School of Music (OSM) launched
2011-09-15

The University of the Free State’s (UFS) Odeion School of Music will be launched at the first Dean’s Concert in the Odeion on the Bloemfontein Campus on Friday, 16 September 2011.

The former Department of Music, in the Faculty of Humanities, has been transformed and will henceforth be known as the Odeion School of Music (OSM). This follows in the path of the corporate transition currently taking place at the university, which aims to reflect the progressive and dynamic striving towards excellence, as endorsed by the UFS Vice-Chancellor and Rector, Prof. Jonathan Jansen, and his management group.
 
Two years ago the faculty formulated a new mission with the aim to become an international faculty of excellence. An important component of it has been to create a pro-active marketing strategy and policy towards internationalisation and curriculum development.
 
The name Odeion School of Music portrays not only an excellent asset in the Free State, but also nationally and internationally. The school’s new name bears the respected Odeion brand and a number of successful and respected ensembles operate under this brand. These include the acclaimed residential Odeion String Quartet, as well as the Music Department’s student ensembles, the Junior Odeion String Quartet, the Odeion Sinfonia, and the Odeion Choir.
 
According to Prof. Nicol Viljoen, the Chairperson of the OSM, the name change was motivated by the following objectives:
  • The idea of a school within the Faculty of Humanities not only reflects an academic profile that does justice to the intention of the Department to reposition itself, but also simulates the current identity of the unit. This encompasses diverse thematic entities not only from an academic perspective, but also from a community and cultural perspective. The unit does this through providing services, which include arts entertainment, the provision of facilities, as well as a strong emphasis on community development.
  • With regard to an international perspective, it provides attractive possibilities not only from the perspective of a marketing and publicity profile, but also with regard to the identity of the unit.  
  • Hypothetically the new name allows more flexibility to complement the profile with reference to newly anticipated developments. These include the application of prestigious international experts as artistic fellows, membership to progressive European, jointly developed degree programmes and curriculum development initiatives, the founding of a chair in Orchestra Conducting, a master’s degree in Arts Management, as well as the incorporation of bio-kinetics in the teaching methodologies of performance practice, to name but a few.
  • From a management perspective it could also consolidate the perspective of scarce skill specialisation.
  • To give momentum to the establishment of the OSM, Mr Marius Coetzee was appointed as Innovation Manager. He is a former Project Manager of the European Degree in International Music Management – a joint degree initiative between three Universities from Norway, the Netherlands and Finland, funded by the EU in Brussels. His aim will be to develop and investigate aspects such as internationalisation, marketing, pro-active recruitment strategies, curriculum development and innovative teaching methodologies.
Mr Coetzee said music conservatories, from both European and American perspectives are managed and maintained as highly successful and substantial brands. From the European perspective some examples include the Sibelius Academy in Helsinki (Finland), the Liszt Academy in Budapest (Hungary), the Grieg Academy in Bergen (Norway) and the former Sweelinck Academy in Amsterdam (Netherlands). Similar to the South African milieu, the majority of music conservatories in the USA and Canada are resident within an academic university.
However, unlike the South African reality, the majority of these institutions have a value-added identity portrayed by a specific name. Such an example is the renowned Peabody Conservatory of the University of Baltimore or the Jacobs School of Music at the Indiana University Bloomington, to name but a few.
 
The Dean’s Concert will highlight performances of students in the school. The concert will probably become a regular event in future Spring Music Festivals.
