Sustainable and miniaturized electrochemical sensors for glyphosate and parabens: integrating biomass‐derived carbons, FDM fabrication, and portable instrumentation

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract Glyphosate and parabens are chemically distinct emerging contaminants whose field monitoring is constrained by complex matrices and by the cost and infrastructure requirements of conventional laboratory methods. This review evaluates whether biomass‐derived carbon materials, fused deposition modeling (FDM), and portable electrochemical ...

Styrene and its natural analogues: accumulation and sustainable production methods

open access: yesJournal 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 ...

A systematic 15N‐amino‐acid tracer framework to identify sources of pelagic marine organic matter

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurately tracing organic matter sources in marine systems remains challenging, particularly where natural and anthropogenic inputs coexist. Compound‐specific stable isotope analysis of amino acids (CSIA‐AA) offers strong potential for organic matter source discrimination, but its application is limited by the small number of validated δ15N ...

Automatization of multistep sample preparation for microplastics monitoring in aquatic environments

open access: yesLimnology 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

open access: yesMacromolecular 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.
