Styrene and its natural analogues: accumulation and sustainable production methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...

Automatization of multistep sample preparation for microplastics monitoring in aquatic environments

Limnology and Oceanography: Methods, EarlyView.
Abstract Microplastics (MP) have been found in every environmental compartment in urban and remote areas. Although their ubiquity is widely recognized, the lack of harmonized protocols for sampling, sample preparation, and particle identification/quantification hinders comparability among studies.

Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction

Macromolecular Rapid Communications, EarlyView.
This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Rheological Assessment of Polymer Melts and Networks: From Degradation to Recyclability

Macromolecular Rapid Communications, EarlyView.
Rheology provides a powerful analytic tool for tracking polymer degradation and structural evolution across manufacturing, service, and recycling. Linear and nonlinear rheological techniques reveal changes in molecular architecture, network stability, and processing history.

Inverse Design of Copolyamides via Sequence‐Sensitive Multifidelity Hybrid Models and Teacher–Student Genetic Algorithm

Materials Genome Engineering Advances, EarlyView.
A sequence‐sensitive multi‐fidelity hybrid modeling framework combined with a teacher‐student genetic algorithm enables the inverse design of copolyamides. The hybrid model balances prediction accuracy, sequence‑sensitivity, and computational cost. A two‑tier genetic algorithm can efficiently identify the monomer structures and ratios of copolyamides ...
