Hydrogen Storage Properties of Vanadium‐Decorated Holey Graphyne: A Density Functional Theory Study

open access: yesEnergy Storage, Volume 8, Issue 5, August 2026.
A V‐decorated HGY exhibits strong yet reversible H2 adsorption, delivering a hydrogen storage capacity of 6.43 wt% with an adsorption energy of −0.46 eV and a desorption temperature of 378 K. ABSTRACT Hydrogen storage remains a key challenge for the practical deployment of hydrogen‐based energy systems due to the limited storage capacity and weak ...

Talking Minds: Group Gender Composition and Educators’ Mental State Language in Early Childhood Education and Care

open access: yesSocial Development, Volume 35, Issue 3, August 2026.
ABSTRACT Children's exposure to mental state language (MSL) has implications for their social, emotional and cognitive developmental outcomes. Although parental MSL is found to vary as a function of child gender, gender differences in children's MSL exposure are yet to be considered in the early childhood education and care (ECEC) context.

Radical‐Based On‐Surface Transformation of Nonplanar Aromatics Into Nonbenzenoid Nanographenes

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Formation of radicals in nonplanar hydrocarbons through thermally induced dehydrogenation leads to molecular transformation via intramolecular radical‐based cyclization and dimerization, leading to formation of nonbenzenoid nanographenes. ABSTRACT On‐surface synthesis has emerged as a powerful tool for atomically precise C─C bond formation, enabling ...

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3775-3795, July 2026.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

A Review of Black Phosphorus‐Based Materials: From Preparation Strategies to Characterization Techniques

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
The structure, properties, preparation methods, and characterization techniques of BP. As a typical 2D layered material, black phosphorus (BP) demonstrates exceptional promise in various fields, particularly in energy storage for alkali metal‐ion batteries. However, its distinctive structure and properties, together with the compositional complexity of
