Environmental Chemist Postdoc @MeckingGroup @UniKonstanz Biodegradation of polymers in the environment. My latest work: https://t.co/GK1PFFjPAY
Joined November 2020
Can we make polymers from broad mixtures of monomers with diff. lengths (e.g., aliphatic diacids made from cat.-ox. of waste PE)? 🗑️➡️⛓️ What kind of materials might we be able to get? Read below in @angew_chem to see some 1st answers! @MeckingGroup

We are thrilled to announce our newest publication in @ACSSustainable We report the successful synthesis of a biodegradable vulcanized polyester-based rubber exhibiting elastic properties. Solvolysis to the monomer enables recycling. Check it out: https://t.co/sCVmcQ4PED

The cross-linked nature of vulcanized rubbers as used in tire and many other applications prohibits an effective closed-loop mechanical or chemical recycling. Moreover, vulcanization significantly...

On the back of a new publication using this method 🛠️, I received an email today that 1 year out from publication our manuscript on tracking 🔎13C-labelled biodegradable 🌿polymers⛓️ in @NatureComms has been downloaded over 7,000 times! 🤯 Check it out open access below 👇
With biodegradable plastics, we want to be sure that they actual biodegrade, right? 13C-labelling of poly(butylene succinate) unequivocally showed biodegradation in soil and let us precisely close mass balances on polymer-C. https://t.co/a4kDMCNXkW But that’s not all…

Could we make recyclable and degradable polyesters from #biowaste? @TaylorFNelson and colleagues show that the small monomers found in feedstock or #biomass can be used to make longer chains. This could be the next step towards closed-loop #recycling. https://t.co/MZecducCeo

@angew_chem @MeckingGroup We used model systems of diacids with diff. lengths to make ductile, recyclable, degradable polyesters in collab. with M.Sander @usys_ethzh. Shows possibility to make polymers from mixed-monomer feedstocks, incl. ox. PE waste, or bio-based source materials!

A week in Woods Hole flew by! Lots of good work on the NMR with great @WHOI colleagues @bdbjames @Chris__Reddy Yanchen Sun & Collin Ward. Looking forward to more cool stuff! For some info on what we’ve been up to see our paper in Analytical Chem on DOSY for plastics! 👇

Enjoying San Francisco and the start of the #ACSFall2023 meeting! I will present Monday 14:30 in Moscone West 3006 in the ENVR section And have a poster Tuesday from 19-21 in Moscone Hall F in the PMSE section

Main applications we highlight are analysis of consumer plastics and following polymer transformations, such as environmental Photodegradation. See more for yourself! Open Access!

We also applied DOSY to different polymers to highlight the wide applicability thermoplastics + water-soluble polymers. Can greatly reduce solvent req. and throughput compared to GPC/SEC!

We highlight some important considerations for preparation of polymer samples for DOSY. A key is concentration which of course effects solution viscosity and therefore diffusion! But, DOSY can be applied across a range of conc., which could have different advantages

I was happy to participate this is great work🧑🔬in my research group @MeckingGroup at @UniKonstanz ! (press release below) We presented a strong HDPE-like 💪 polyester that shows enzymatic hydrolysability 🦠and compostability Find it open-acess 👇 https://t.co/8M9iYqQYrf
onlinelibrary.wiley.com
While it resembles high density polyethylene with regard to its mechanical properties and solid-state structure and has a high melting point (Tm=96 °C), the novel polyester-2,18 material at the same...
A polyester plastic of great mechanical stability, which is also easily recyclable and even compostable: Stefan Mecking, #UniKonstanz chemist, and his research group present a new material. Details: https://t.co/2mPR7ZIwAZ
