Recent Advances in Ionizing Radiation as a Nonequilibrium Chemical Field for Catalysis
Carbon and Hydrogen, EarlyView.Ionizing radiation acts as a nonequilibrium chemical field that generates reactive species and structural perturbations. These radiation‐induced effects bridge catalytic material construction, including metal loading, framework evolution, defect engineering, and carbon‐network reorganization, with selective transformations such as oxidation, reduction,

Unbiased Reaction Network Exploration of C–C Coupling in Methane Dehydroaromatization Over Mo‐ZSM‐5
Chemistry – A European Journal, EarlyView.Automated reaction route mapping reveals distinct methane coupling pathways over mono‐ and dinuclear Mo carbide species in ZSM‐5. Mononuclear [MoC]2+ selectively forms desorbable C2H4, whereas dinuclear [Mo2C2]2+ promotes strongly adsorbed C3/C4 intermediates linked to coke formation.

Chemie Ingenieur Technik, EarlyView.Growing air traffic increases the contribution of aviation fuels to global emissions. With few viable alternatives for decarbonizing aviation, Sustainable Aviation Fuels (SAF) are a key lever. Green methanol enables a flexible synthetic production pathway, but realizing a specification‐compliant 100% drop‐in fuel requires overcoming significant ...

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...
