Discrimination of Truffles and Truffle Oils by a Metal–Organic‐Framework‐Based Electronic Nose

open access: yesAdvanced Sensor Research, Volume 5, Issue 9, September 2026.
A portable electronic nose based on MOF‐coated QCM sensors enables rapid authentication of truffles and truffle‐derived oils. Characteristic response patterns distinguish fresh truffle species, homemade and commercial oils, and samples adulterated with dimethyl sulfide.

Fabrication of Effective Room Temperature Chemiresistive Gas Sensor by Utilizing p‐type CuO @ n‐type g‐C3N4 Heterojunction Nanocomposite

open access: yesChemNanoMat, Volume 12, Issue 9, September 2026.
In this work, we present a low‐cost chemiresistive gas sensor operating at room temperature based on a CuO@g‐C3N4 p–n heterojunction nanocomposite synthesized via a simple hydrothermal method. The fabricated sensor exhibits fast response/recovery times and low detection limits toward both H2 and CO2 gases, attributed to efficient interfacial charge ...

Fluorescence Color Changes of Molecular Aggregation Processes of Difluoroboron β‐Diketonate Complexes With Heterocyclic Ring During Solvent Evaporation

open access: yesChemPhotoChem, Volume 10, Issue 9, September 2026.
Fluorescence visualization captures liquid‐like clusters (LLCs) during crystallization of furan‐ and thiophene‐based β‐diketonate–BF2 complexes. Enhanced dipole moments induce competition between H‐ and J‐type stacking, broadening emission, and suppressing the formation of a distinct redshift band.

2‐Vinylpyridine Plasma Polymers as Anion Exchange Membranes in Low Temperature Electrolyzers: Structure‐Property Relationships and Proof of Concept

open access: yesPlasma Processes and Polymers, Volume 23, Issue 9, September 2026.
2‑vinylpyridine (2VP) plasma polymers were deposited by PECVD and post‐functionalized. Chemically homogeneous films containing vinyl pyridinium groups with competitive ionic conduction were obtained. A water electrolysis cell using a 2VP plasma polymer as an anion‐exchange membrane reached 1 A·cm−2 at 2 V, demonstrating a highly promising proof of ...
