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 ...

Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

open access: yesResponsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Solar‐Powered Water Depollution Through a Bioinspired Device Based on ZIF‐8 Loaded Macroporous Hydrogels Prepared via Ice‐Templating

open access: yesSmall, EarlyView.
ABSTRACT Water pollution poses a constant threat to the environment and is one of the central causes for global shortage of clean water. Metal–Organic Frameworks (MOFs) have emerged as highly efficient adsorbents; however, their application is limited by their common production as fine powders, which hinders recovery and reuse.

A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

open access: yesSmall, EarlyView.
This work describes a green and scalable approach to robust and flexible heterometallic MOFs, MIP‐215's, with tunable photoactivity for efficient, noble‐metal‐free solar hydrogen production. ABSTRACT Photocatalytic particulate systems offer a cost‐effective solar hydrogen production but are generally limited by narrow visiblelight absorption and poor ...

Seeded Growth of Plasmonic Core‐Shell NU‐1000 NanoMOFs With Intracellular Optical Readout

open access: yesSmall, EarlyView.
Seed‐mediated growth yields plasmonic core‐shell nanocomposites by encapsulating gold nanoparticles within NU‐1000 nanoMOFs, preserving morphology and optical response. The materials exhibit tunable photoluminescence quenching, efficient photothermal heating, and SERS activity.

Preserving Hierarchical Integrity During Primary Structure Modification of Spherulitic MOFs

open access: yesSmall, EarlyView.
A MOF‐74‐type zinc framework self‐organizes into well‐defined spherulitic superstructures while allowing precise covalent post‐synthetic modification (PSM) of the linkers. A built‐in tetrazine enables fast inverse electron‐demand Diels–Alder (iEDDA) functionalization to uniformly install primary amines.

Kinetics of polymer crystallization

open access: yes, 2001
Kinetics of three steps of complex crystallization of poly(N-methyldodecano-12-lactam) were studied by DCS using an Avrami model. Mechanism of respective isothermal steps involves mixed heterogeneous/homogeneous nucleation (primary melt crystallization ...
