Cross‐Carboxylation of Methanol and Other Alcohols With CO2 Into Asymmetric Alkyl Methyl Carbonates Over a CeO2 Catalyst

open access: yesChemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
One‐pot synthesis of asymmetric organic carbonates from CO2, methanol, and other alcohols was demonstrated in the presence of CeO2 catalyst and 2‐cyanopyridine dehydrant. This reaction proceeded through two reaction pathways—direct route via cross‐carboxylation and indirect route via production of DMC and subsequent transesterification.

Experimental Proof to Natural Hydrogen Generated Through Serpentinization of Olivine at Room Temperature and Ambient Pressure With Mechanochemistry

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
This work shows experimentally the possibility of serpentinization (main mechanism of natural hydrogen) at room temperature and ambient pressure, which may provide the rapidly growing hydrogen economy with inspirations to explore new natural hydrogen deposits and new methods for hydrogen production. Natural hydrogen, or “white hydrogen,” is a promising

A multiscale study on the microstructure and hardening models of the irradiation defects on reactor pressure vessel steels: Modelling and experiment

open access: yesJournal of Materials Research and Technology
Irradiation defects are known to impede the dislocation motion in irradiated reactor pressure vessel (RPV) steels. However, consistent experimental studies of the respective irradiation defects and relevant theoretical studies of the interaction ...

Dynamic recrystallization and microstructural evolution in 40CrNi2MoV steel during forging

open access: yesiScience
Summary: Reactor pressure vessel (RPV) studs require uniform microstructures for reliability. A strain-compensated Arrhenius constitutive model and dynamic recrystallization (DRX) model for 40CrNi2MoV steel were established via isothermal compression ...
