Progress in Surface‐Enhanced Raman Scattering‐Based Volatile Organic Compounds Detection: Materials, Application, and Prospects

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The detection of volatile organic compounds (VOCs) holds significant implications in environmental monitoring and disease diagnosis. Traditional gas detection technologies are constrained by complex operation and high cost, thereby failing to satisfy real‐time detection demands.

Single‐Molecule Imaging and Spectroscopy Enables Quantification of Location‐Dependent Light–Matter Interactions on Nanoantennas

Small Science, Volume 6, Issue 3, March 2026.
The fluorescence intensity as well as the spectral shape of the emission of single dye molecules strongly depend on the molecules’ exact position relative to plasmonic nanoparticles in hybrid systems. By point‐spread function modification analysis, the vertical binding location of single fluorophores on gold nanocones is obtained and correlated to both

Focused Thermal Emission From a Radiative Metasurface

Small Structures, Volume 7, Issue 3, March 2026.
MIM‐type metasurfaces, consisting of metal‐dielectric‐metal nanostructures, are promising materials for achieving highly efficient photothermal conversion. By introducing a structural arrangement inspired by metalens, which can focus light using a two‐dimensional lens, into this structure, we have achieved filter‐less light‐focusing operation.

Seismoacoustic Analysis of Possible Vent‐Drying Sequence During Phreatomagmatic Activity on 13 July 2021 at Semisopochnoi Island, Alaska

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pulse‐like infrasound accompanying volcanic phenomena sometimes suggests interaction with water at the crater. We focus on pulse‐like infrasound observed at Semisopochnoi Island in the Aleutian Arc, Alaska, during the phreatomagmatic activity on 13 July 2021.

Surface‐Enhanced Infrared Absorption on Arranged Pt Nanoantennas

ChemPhysChem, Volume 27, Issue 4, 25 February 2026.
We investigated the infrared transmission absorption of benzene‐adsorbed Pt nanoantennas on Si substrates under ultra‐high‐vacuum conditions. A scanning electron microscope image shows a high aspect ratio of the Pt nanoantennas. As shown in the transmission absorption spectrum, surface‐enhanced infrared absorption (SEIRA) is observed for the C–C ...
