GML joins EPSRC RE3 project- Rethinking Resources and Recycling

Manchester is at the heart of the UK’s shift to a sustainable plastic society. Greater Manchester plans to minimise single-use plastics by 2020, providing a leading example to the rest of the UK, where a 2042 target has been set by the government for elimination of avoidable plastic waste. It is essential that we realise that often plastic is the best material for the job – from both an energy and a property perspective – and thus it is about intelligent choices of how we reuse, recycle and degrade these materials that underpins progress. Following our move to the University of Manchester, the Green Materials Laboratory are excited to be collaborating on the EPSRC funded RE3 project, with the aim of addressing plastic waste stream and supply chain challenges in the UK.

This interdisciplinary project seeks to target both the technological and societal sides of the 5 million tonnes of plastic waste being generated in the UK annually. A consortium has been formed of manufacturing, social, and material scientists, as well as several other academic and industrial partners, to provide practical solutions and thought leadership in valorising these plastic waste streams and creating sustainable business models. The project also aims to enable development of new degradable polymers to reduce our current reliance on single-use plastics from non-renewable feedstocks. Collaborating in this consortium allows us the unique opportunity to couple our expertise with that of other academics at the University of Manchester, as well as both industrial and local authority partners. We appreciate the new perspectives on what is a massive global challenge!

Ring-opening polymerisation of dioxolanones

Congrats to Yuechao and Mitch for their latest work on ROP of dioxolanones!

The paper builds on our previous work on the synthesis of poly(α-hydroxy acid)s where we found elimination of formaldehyde to be the favoured driving force. Here, the impact of a competing Tischchenko side reaction via the liberated formaldehyde was probed and found to lead to significant reductions in molecular weight. Polymerisation under dynamic vacuum reduces the tendency towards this side reaction through removal of formaldehyde, while use of a water jacketed reactor avoids loss of monomer. Crystalline poly(mandelic acid) was formed under these conditions, giving thermal properties competitive to that of polystyrene!

Morpholino Polymer Hydrogels as miRNA Sensors

Check our Gerry Langford’s new paper in ACS Sensors: It details our work in developing hydrogels with morpholino-based crosslinks that serve as sensors for single stranded oligonucelotide sequences. They show a remarkable improvement in sensitivity, salt tolerance, and temperature stability compared to ssDNA analogues and have detection limits as low as 10 pM. They even work using a simple mobile phone camera!

Work with the GML, work with industry leader!

As part of our new transition to the University of Manchester, we are seeking an enthusiastic person to work with us and an industry leader in glass fibre insulation on a Knowledge Transfer Partnership (KTP) project. The ideal person will had a PhD in polymer synthesis or composites, with an expertise in sustainability a bonus. Above all, we are looking for an exceptional and independent learner, scientist and leader to undertake this 36-month project which has an overall aim of developing sustainable glass fibre insulation formulations.

The position will provide you with a unique opportunity to improve the sustainability of glass fibre insulation through their knowledge of polymer chemistry. Translating fundamental commodity polymer chemistry into the unique field of glass fibre composites will require a diverse knowledge of sustainability, composites, polymer chemistry, synthesis and characterisation. It will allow for the rapid development, pilot and scale-up of solutions to reduce the environmental footprint of a major construction product, making the process as “green” as possible whilst retaining or improving material performance. Understanding the applicability of potential solutions to fit with existing company infrastructure will provide ideal training as a transition to a career in the chemicals or polymers industries in the UK, but also extensive experiential learning in communication and leadership. This collaborative project will be directly connected to the training and development aspect of the KTP, with integration of both composites and sustainability training into the Associate’s role.

Based at the University of Manchester School of Materials and extensive travel to company premises, You will work directly with supervisors from both the University and the company and will use the facilities and resources of both organisations.

Topological Control from a Synthetic Polymer

Congrats to Mohammed Alkattan and our University of Glasgow collaborator Joelle Prunet who have just had a really cool paper accepted as a VIP article in Angewandte Chemie:

The paper details our work on creating stereoregular cyclopolyethers. Ring-closing metathesis from an isotactic polyether affords the target cyclopolyether. Stereoselective cis-dihydroxylation gives a PEGose framework that mimics the helical ladder structure of amylose. This topological control of synthetic polymer frameworks is a really tough challenge in polymer science in the quest for biopolymer mimics. Great work!

Joseph Black Stars

Big congratulations to Meng Wang (2nd Place Talk Prize – Materials Chemistry) and Joanne Dunne (2nd Place Poster Prize – Synthesis and Catalysis) for their award winning work at the 4th annual Joseph Black Conference on 31 May.

Big congratulations to the rest of the group as well – Gerry gave a great talk in the Chem/Bio section on his sensor work; Dan and Mo both gave great talks in the Syn/Cat section (although Dan needs to get his face onto Titanium Man’s body, too…); and both Vishal and Yas had really attractive posters presenting their work on new polymers.

Great work!
