Electrokinetic Manipulations Combined With Direct and Ambient Ionization Mass Spectrometry

open access: yesMass Spectrometry Reviews, Volume 45, Issue 2, Page 244-259, March/April 2026.
ABSTRACT Mass spectrometry (MS) is a powerful analytical technique that typically involves sample preparation and online analytical separation before MS detection. Traditional methods often face bottlenecks in sample preparation and analytical separation, despite the rapid detection capabilities of MS.

Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation

open access: yesAngewandte Chemie, Volume 138, Issue 9, 23 February 2026.
Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...

Quantizing DNA Metallization for Site‐Defined Growth of Single Quantum Emitters

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
Predictive design rules guide DNA origami‐templated synthesis of atomically precise silver nanoclusters. Controlled nucleation yields single emitters with nanometer registration and reproducible fluorescence signatures, paving the way toward programable quantum photonic architectures and nanoscale device integration.

The Nasal Microbiome and Associations With Environmental Exposures and Respiratory Health

open access: yesAllergy, Volume 81, Issue 3, Page 750-763, March 2026.
This study evaluates the association of the nasal microbiome with air pollutants, meteorological conditions, and respiratory health in adolescents. Bacterial diversity is positively associated with hay fever and short‐term NO2 exposure, and negatively with temperature. A Moraxella‐dominated nasotype is linked to lower O3 exposure and higher temperature
