 Welcome to Williams Research Group website. These pages provide some introduction to our latest news, research interests, academic publications, group members, outreach and engagement activities and information on how to apply to join us.

Our research focusses on sustainable chemistry, carbon dioxide utilization, catalysis, polymer chemistry, materials, inorganic/coordination and organometallic chemistry.  We are a diverse, multi-national and multi-disciplinary team whose objective is to provide innovative solutions to major global and environmental challenges. We work in modern synthesis laboratories in the chemistry research laboratory and have specialist laboratories equipped to scale and monitor polymerizations, process and understand polymer properties for a wide range of applications. Our polymers are used as plastics, elastics, adhesives, surfactants, coatings, in solid state batteries, consumer products, electronics and many more.  All our polymers are designed to be renewably sourced, show excellent properties for their target application and to be fully recyclable after use. We work with many different academic partners to solve these problems across fields, including engineering, materials science, computing, environmental economics, policy and law. We also often work in partnership with industries, businesses, charities and with individuals motivated by sustainability challenges. Our team regularly undertaken outreach and engagement activities, including Charlotte's work with professional societies to provide future technology policy briefings.

    • The Royal Society policy briefing "Catalysing Change: Defossilising the Chemical Industry" was launched today in London. The report emphasises the importance of developing the science and technologies which will allow the UK to decouple its future chemical industry from fossil fuels. It presents scientific explanations, written for the non-technical audience, of current options for sourcing chemicals and materials from biomass, carbon dioxide, and industrial wastes. The policy briefing was underpinned by consultations and expert input from leaders across academia and industry. Charlotte served on the working group for the report, collaborating closely with the experts in policy at the Royal Society; she presented today, at the launch event, on the science and technology options for the future chemical industry. There were also presentation from Prof. Graham Hutchings CBE FREng FRS, Prof. Matthew Rosseinsky OBE FRS, and Neil Johnson (Director, Department for Business and Trade) and a round table discussion and Q&A session with all presenters.

The latest DPhil graduate is Dr Holly Yeo! Very many congratulations to Holly on a successful DPhil viva examination. Holly's thesis entitled "New Polymerization Approaches for Future Batteries" was co-advised with Prof. Mauro Pasta and Prof. Peter Bruce FRS in the Department of Materials and with Dr George Gregory (RS Dorothy Hodgkin Fellow). With thanks to the examiners Prof. Paul Beer and Prof. Remzi Becer. Holly has been a fantastic colleague and researcher in the group, working hard to develop new polymer electrolytes, binders and elastomers - her work has brought together our discoveries in switchable catalysis and block sequence selectivity, and also allows for the replacement of PFAS in solid state battery applications. Holly was funded by the OxICFM CDT and was also a key group member of the outreach team. She helped put together the London Design Museum Exhibition of Williams Group Chemistry for the 'Waste Age' Exhibition and undertook several other outreach and engagement activities for the Dept. Chemistry. We all wish her well in her future career in the civil service and in her move to Manchester.

  • ‘Cleaning up cleaning: policy and stakeholder interventions to put household formulations on a pathway to net zero’

    • Researchers from the group, along with a team in environmental economics at the Oxford Smith School and working with Unilever Home Care have jointly reported on the policy interventions required to improve sustainability of household products. Their aim is to reduce the consumption of fossil-fuel derived feedstocks used in many chemical formulations ubiquitous in everyday household products.

  • ‘Designing a circular carbon and plastics economy for a sustainable future’ – Perspective in Nature published
    • A collaborative team from the Williams group, as well as other teams in law and environmental economics, published a perspective piece in Nature today detailing a set of ambitious targets to achieve a net zero plastic economy. Their report analyses the current plastic economy and several proposed scenarios to combat the multifaceted issues with current plastics manufacturing and use. They find that only the most drastic of measures will be sufficient to achieve substantial change by 2050. Their proposal for the future of the plastics economy centres on: a reduction on plastic consumption by half, replacement of all fossil-fuel-based plastics with renewable feedstocks, designing materials to enable 95 % of all plastics to be recycled, and minimizing environmental impacts by removing pollution and hazards to all organisms and decreasing the carbon footprint in their lifecycle.
    • The team have been advising the UN Environment Programme and UK Government to aid with the ongoing discussions around the second global pollution treaty, due for completion in 2024, focussing on the lifecycle of plastics.

  • Hot Paper Angew. Chem. Int. Ed, May 2021  

    • Congratulations to Alex for an Angewandte Chemie 'hot paper' for his work on heterotrimetallic catalysts for carbon dioxide copolymerization and switchable catalysis Alex's paper describes a series of new heterometallic catalysts featuring Na(I) and Zn(II) ions which show efficient catalysis for carbon dioxide/epoxide ROCOP. The catalysts allow for the selective placement of ether linkages in the polymer chains and particularly at chain ends, which serves to stabilise the resulting PCHC. The paper includes detailed kinetic investigations which shed light on the catalysts unusual selectivity and allow for understanding of their performances in switchable polymerizations using epoxide, carbon dioxide and anhydride monomers. It also includes a structure-activity study using other metals which underscores the unique and important role for Na(I) in the best performing catalysts.

  • Science to Enable Sustainable Plastic , June 2020
    • The worst environmental impacts of plastics are a common sight in the news or on social media – but they also fulfil vital roles in society, and in some cases can even be a more sustainable option compared to alternatives. But more research is urgently needed in order to make them fit for the future. In November 2019, Charlotte Williams chaired a group of researchers, representative of learned societies, and funders from China, Germany, Japan and the UK at the Chemical Sciences and Society Summit (CS3). Over the course of a three day summit, they developed a plan for how to create a circular economy for plastics, preserving the crucial function they serve in society while introducing much better recyclability and reusability into their design. Today we’re announcing publication of the white paper, which outlines four major research challenges – areas in urgent need of development.

  • Congratulations to Arron on the publication of his work on heterodinuclear catalysts for carbon dioxide and epoxide copolymerization in Nature Chemistry. The paper describes a highly active and selective Co(II)Mg(II) catalyst which shows remarkably enhanced performance compared to any homodinuclear analogue.  Through detailed investigation of the polymerization kinetics, the factors influencing the synergy in this catalyst are also explored, with the Co(II) being responsible for reducing the transition state enthalpy and the Mg(II) reducing the transition state entropy compared to homodinuclear analogue catalysts.  This rare insight into how heterodinuclear synergy or cooperativity enhances performances may be more generally applicable and could be a new design feature to exploit in preparing polymerization catalysts.
