Absorption and translocation of 14C‐propiconazole associated with two adjuvants in young coffee plants

open access: yesPest Management Science, EarlyView.
Experimental workflow evaluating 14C‐propiconazole absorption and translocation in Coffea arabica with two biodegradable adjuvants, quantified at six post‐application time points using radioscanner and liquid scintillation spectrometry. Abstract BACKGROUND This study evaluated the absorption, translocation and distribution of 14C‐propiconazole applied ...

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Combining Laser‐Induced Edition to Collision‐Induced Sequencing of Digital Oligomers in a Single Gas‐Phase Experiment

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale To increase the confidentiality level of molecular tags, binary information can be hidden in sequence‐defined oligomers using isobaric monomers including a photo‐sensitive one, which mass can be modified upon light irradiation. Reading such secured data requires light edition prior to MS/MS sequencing, which was investigated here in ...

Cooperative Regulation of Defect‐Mediated Molecular Recognition With Single‐Walled Carbon Nanotubes

open access: yesSmall, EarlyView.
Defect‐mediated sensing in SWCNTs arises from the cooperative interplay of defect characteristics, density, heterogeneity, analyte properties, corona composition, and environment. Understanding these interconnected variables enables tunable fluorescence modulation, selective molecular recognition, ratiometric sensing, and sensitive detection in complex

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

open access: yesThe Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

open access: yesThe Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...
