Renewable methacrylate resin for vat photopolymerization derived from post‐consumer polyester waste

open access: yesPolymer International, EarlyView.
End‐of‐life poly(ethylene terephthalate) was upcycled into a renewable methacrylate crosslinker using microwave‐assisted methacrylation and applied in vat photopolymerization. The recycled resin enabled high‐resolution 3D printing with tunable mechanical performance, highlighting a circular strategy to reduce fossil‐based photopolymer feedstocks ...

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

open access: yesJournal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Opposite Trends in Glass Transition and Vogel Temperatures in Long‐Chain Branched Poly(l‐Lactic Acid)

open access: yesJournal of Polymer Science, EarlyView.
The glass transition temperature (Tg), as determined by conventional DSC, increases from 326 K to 329 K while the Vogel temperature (Tv) decreases from 271 K to 255 K as the number of branch points per molecule increases from 0 to 3.3. ABSTRACT Poly(l‐lactic acid) (PLLA) is widely used as both a commodity thermoplastic and for engineering applications,

Roll‐to‐Roll Processing of Biodegradable Multilayer Barrier Packaging Structures

open access: yesPackaging Technology and Science, EarlyView.
This work demonstrates that novel packaging materials built using biobased and biodegradable materials can be produced in pilot‐scale and converted into functional barrier packaging. The proposed structures are anticipated to make a strong impact in use‐cases where the risk of environmental littering is elevated, such as snacks and take away meals ...

Peptide Fingerprinting of Single Protein Molecules Using In‐Plane Nanopore Sensors Integrated to an Extended Immobilized Nanoscale Enzymatic Reactor (eINER)

open access: yesSmall Methods, EarlyView.
The protein Time‐of‐Flight (P‐ToF) chip can peptide fingerprint a single protein molecule by subjecting it to a solid phase endopeptidase cleavage reaction in‐line with a combination of resistive pulse sensing of the resulting single peptides and machine‐learning aided identification.
