Mode‐Locked Pulse Generation in Plasmonic Lattices

open access: yesLaser &Photonics Reviews, EarlyView.
The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

Bioinspired, Guanidinium, and Indole Modified Poly(glycidyl ether)s as Highly Efficient Vectors for Polyplex‐Mediated Gene Delivery

open access: yesMacromolecular Rapid Communications, EarlyView.
Guanidinium‐ and indole‐functionalized poly(glycidyl ether)s were developed as non‐viral gene delivery vectors with tunable hydrophilic–hydrophobic balance. All polymers formed stable DNA polyplexes, while moderate indole content yielded the highest transfection efficiency at low N/P ratios.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

open access: yesNordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Microwave‐Assisted Organic Syntheses in Deep Eutectic Solvents: A Win‐Win Association for Sustainable Chemistry

open access: yesChemistryOpen, EarlyView.
In organic synthesis, deep eutectic solvents (DES) have demonstrated their ability to be used as reaction media for the development of reactions in line with green chemistry principles. This review presents an overview of microwave‐assisted organic synthesis in DES, highlighting the diversity of uses for these solvents, their role in mechanisms, the ...

2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

open access: yesChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...

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.

Exploring the Fragmentation of Sodiated Species Involving Covalent‐Bond Cleavages for Metabolite Characterization

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Electrospray (ESI), the most popular desorption/ionization technique used in mass spectrometry‐based metabolomics, generates both protonated and deprotonated molecules, as well as adduct ions, sodium being the most frequent monoatomic cation entering their composition.

Supramolecular Assemblies of Self‐Immolative Janus Dendrimers With Rapid Photodegradation Response

open access: yesSmall, EarlyView.
Self‐immolative Janus dendrimers assemble into spherical nanoparticles with solid cores. Upon irradiation, rapid end‐to‐end depolymerization triggers a unique degradation pathway from spheres to crescents within minutes, enabling on‐demand release of encapsulated cargo.

Illicit Drug‐Derived Volatile Organic Compounds as Markers for Application in Noncontact Detection Technology

open access: yesThe Chemical Record, EarlyView.
This review highlights the characteristic odor markers of illicit drugs, emphasizing volatile markers from both natural and synthetic sources, and explores the shift from canine‐based detection to emerging noncontact sensing technologies. Illicit drug use remains a global concern, requiring effective detection methods to counter evolving concealment ...
