Magdalena Beres 🇺🇦

A bit late post but happy I could attend #MACRO2024 this year. It was a bit hectic but totally worth it, great to catch up with friends old and new :) Now back to maternity break, see you soon! @mothersinsci

@fred_opj Thanks Fred! Yes, this is really interesting, I have even carried out photoRAFT with light wavelengths which had no overlap with the abs spectrum

@MagdaBeres Awesome paper Magda! Love the redshifted reactivity compared to the absorbance spectrum!

Interested in RAFT? Polymerization kinetics? Photopolymerizations? Look now further and check out our work on the effect of monomer, RAFT agent and light intensity on the kinetics of photoiniferter-RAFT polymerization

We are back tomorrow for week 3, in which we will dive into the intricacies of colloids with @JulianHeuer and @BelluatiAndrea. See you at 15:00 UK time!

Ready, set, register!! We have a group of fantastic PhD students and postdocs ready to share their recent research in macromolecular science. Our FREE weekly webinars start Tue 5-March at 15:00 (UK). Sign up using the link below - and tell your friends! 😊 tinyurl.com/YMT2024

Want to know how the wavelength of light or monomer stability affect PI-RAFT? Look no further and make this January a bit brighter with photochemistry! pubs.rsc.org/en/content/art… #PolymerChemistry #OpenAccess @TeamPerrier @PolymChem @warwickchem

@AmyGodfrey23 @LabGibson @MRCDTP_IBR @markvanraaij @craigpthomp Congrats! :)

Happy to share that I passed my PhD viva on Friday! Thankyou to my amazing lab on IBRB floor2, @LabGibson, @MRCDTP_IBR and of course a big thankyou to my examiners @markvanraaij and @craigpthomp for some great discussions!

Bitter-sweet feelings as my time at Monash is over. I had a great time exploring flow chemistry and Australia. Huge thank you to everyone in the PRD group,you made me feel very welcome. Thanks to Tanja Junkers and @SebPerrier for this opportunity! @TeamPerrier

@AnastasakiLab @MariaNefeli12 Well done @MariaNefeli12, congratulations!

@APME2023 was a blast! What made it even better was the fact that our PhD student @MariaNefeli12 won the award for the best oral presentation! Big thanks to organizers & @PolymChem @RSCApplied @MaterHoriz for sponsoring the award and we hope to see everyone again at Catania!🇮🇹

@ItsJamesWilson @pratik_gurnani The old ones we have at Warwick are from Mylee brand but I'm not sure if their design hasn't changed over time

@pratik_gurnani Yeah, I remembered having an old one back in Warwick that had no timer, but cannot for the life of me find one without. I'm not clicking every 2 minutes over the course of 4-6 hours!

Does anyone know where to get a cheap UV lamp for thiol-ene reactions? One that stays on and not a short timer. I have no clue where to look.

@ItsJamesWilson You could try using UV lamp used for visualisation of TLCs

@ChemistMhmdJ To improve the second factor (stability of TTC end group) - there are some reports showing that adding a tertiary amine can reduce TTC radical to a TTC anion which prevents degradation. However, we haven’t seen big improvements in our system.

@ChemistMhmdJ Green light works better than blue so likely shifting to even longer light wavelength could improve the livingness. However, this will increase time reaction significantly and can also lead to poor initiation, which will lead to broader dispersity.

What can we learn about photo-iniferter RAFT polymerization of methacrylates using bis-trithiocarbonate RAFT agents? #RSCPoster #RSCMat @TeamPerrier @Polymer_RTP @warwickchem

@ChemistMhmdJ It's a going bit of a long answer but there's quite a few factors to consider here ;)

@Bellotti_Vale @AnastasakiLab How the photocatalyst will affect the recovery of monomer and RAFT agent? Can you remove the Eosin easily?

Check out our latest work on light-accelerated depolymerization using Eosin Y as photocatalyst! How to use visible light to improve depolymerization of RAFT-made polymers 💡 #RSCPoster #RAFT #Depolymerization @AnastasakiLab

@Satu_Hakkinen So in short, I think majority of CTA participates in initiation but I haven't than quantitative studies /3

@Satu_Hakkinen For MMA I suspect it's similar as I don't have (big) initialisation period. I think for PMMA the main problem is the end group degradation which will happen throughout the entire polymerization and this would be applicable to every trithiocarbinate based RAFT agent! /2
