Hydrogen Bonding is Key Factor in Reversible NH3 Uptake Causing Vapochromic and Magnetochemical Switching in Ni(II) Paddlewheel Complexes

ChemistryEurope, EarlyView.
Nickel complexes showing reversible vapochromic and spin crossover behaviors upon coordination and release of NH3 were synthesized. They bear bidentate pyridazine ligands, which allows for formation of hydrogen bonds between NH3 and the ligand in the second coordination sphere.

Selective Modification of the Product Profile of Biocatalytic Hydrolyzed PET via Product‐Specific Medium Engineering

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.

Successive Mechanical Recycling of Poly(lactic Acid) by Injection Molding: Evolution of Molecular, Thermal, and Mechanical Properties

Macromolecular Materials and Engineering, EarlyView.
This study investigated how successive injection molding recycling affects the properties of poly(lactic acid) (PLA). Gel permeation chromatography showed a two‐thirds molar mass reduction after ten reprocessing cycles. Differential scanning calorimetry revealed lower glass transition and cold crystallization temperatures.

Structure‐Aware Machine Learning for Polymers: A Hierarchical Graph Network for Predicting Properties From Statistical Ensembles

Macromolecular Rapid Communications, EarlyView.
This work presents a structure‐aware graph convolutional network that models polymers as statistical ensembles to predict macroscopic properties. By combining topologically realistic graphs generated via kinetic Monte Carlo simulations with explicit molar mass distributions, the framework achieves high accuracy in classifying architectures and ...

Nanoplastics in Depolymerization Products from Hydrolysis of Poly(Ethylene Terephthalate) in the Solid State

Macromolecular Rapid Communications, EarlyView.
Hydrolysis of PET in the solid generates nanoparticles, but thermal signatures of PET were only observed for hydrolysis at 150°C, while oligomers appeared to dominate the non‐monomeric products from hydrolysis at higher temperatures. ABSTRACT Circularity in plastic waste management through depolymerization to monomer is a promising route to address ...

Generating Tagged Micro‐ and Nanoparticles of Poly(ethylene furanoate) and Poly(ethylene terephthalate) as Reference Materials

Macromolecular Rapid Communications, EarlyView.
We successfully developed poly(ethylene terephthalate) (PET) and poly(ethylene furanoate) (PEF) nanoparticles and microparticles, covalently tagged with Alexa Fluor 633 or Alexa Fluor 647, using both mechanical and solvent‐based approaches. The particles displaying hydrodynamic diameters between 200 and 700 nm, exhibited long‐term colloidal stability ...
