3D‐Printed Optical Volatile Organic Compound Sensors Based on Donor‐Substituted Coumarin Thermally Activated Delayed Fluorescence Emitters

open access: yesSmall Science, Volume 6, Issue 6, June 2026.
Donor–acceptor coumarin emitters displaying thermally activated delayed fluorescence (TADF) are formulated into photocurable resins and processed by digital light processing (DLP) 3D printing. The resulting printed materials show a sensitive and repeatable photoluminescence response when exposed to volatile organic compounds (VOCs).

Mixed Oxides for Simultaneous CO and Toluene Catalytic Oxidation: Effect of Mn/Cu Ratio on Catalytic Performances

open access: yesChemCatChem, Volume 18, Issue 7, 14 April 2026.
ABSTRACT Manganese‐copper (Mn‐Cu) mixed oxides are promising catalysts for abatement of incomplete combustion products from domestic wood burning, notably CO and Volatile Organic Compounds (VOCs). In this paper, the influence of the Mn/Cu molar ratio on structure, redox properties, and catalytic performances was investigated.
