Coupled Operando Mössbauer‐Raman Spectroscopic Analysis of Iron Molybdate Catalysts During Oxidative Dehydrogenation

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
We demonstrate the potential of a coupled SMS‐Raman setup for the ODH of EtOH over a Fe2(MoO4)3 + MoO3 catalyst during reductive conditions. Coupling both methods allows to distinguish (sub)surface and bulk properties of the material during catalysis, that can be correlated with activity and selectivity data from mass spectrometry.

Enhancement of the WS2 A1g Raman Mode in MoS2/WS2 Heterostructures

physica status solidi (b), Volume 263, Issue 8, August 2026.
In van der Waals heterostructures consisting of WS2 and MoS2 monolayers, we find a strong, selective enhancement of the WS2 A1g Raman mode due to interlayer coupling and in‐phase vibration of sulfur atoms in the adjacent MoS2 layer. When combined into heterostructures, transition metal dichalcogenide monolayers enable the exploration of novel physics ...

High‐Efficiency Generation of Vectorial Terahertz Beams via Surface‐Wave‐Excited Dielectric Metasurfaces

Small, Volume 22, Issue 46, 18 August 2026.
ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

High‐Performance Near‐Infrared Organic Light‐Emitting Diodes Based on Grating‐Structured Hole Transport Layer

Small Structures, Volume 7, Issue 8, August 2026.
High‐performance near‐infrared (NIR) organic light‐emitting diodes (OLEDs) were achieved by incorporating a one‐dimensional Bragg grating into a thermally cross‐linkable hole‐transporting layer via microtransfer molding. The optimized devices exhibit an emission peak at 880 nm, a maximum external quantum efficiency of 1.55%, and a peak radiant exitance
