A surface diffusion block coefficient and model about coal-adsorbed gas

Meitan xuebao
80%−90% of coalbed methane(CBM)/coal mine gas is stored in adsorbed state, and the diffusion of adsorbed gas is dominated by surface diffusion, which plays a decisive role in the transportation of CBM.

Enhancing Chemical Stability and Molecular Selectivity of Porous Organic Cages via Core–Shell Polymer Coating

Advanced Science, EarlyView.
This study presents an interfacial method to fabricate POC@polymer core–shell nanostructures combining cage porosity with polymer robustness. Through chiral self‐assembly and non‐solvent‐induced surface polymerisation, uniform ∼20 nm polymer‐coated particles are produced.

Moisture sorption isotherms and thermodynamic properties of isomaltulose-enriched mango. [PDF]

J Sci Food Agric
Abstract Background Moisture sorption isotherms and thermodynamic parameters are essential for designing and optimizing food processing and storage systems. This study aimed to evaluate these characteristics in untreated and osmotically treated mango slices, using isomaltulose and sucrose as osmotic agents.

Diamine Grafting of Pyrazole‐Based MOF‐303 for Diluted‐Source CO2 Capture

Small, EarlyView.
Vapor‐phase diffusion of ethylenediamine (EDA) into the pyrazole‐based MOF‐303 framework enables efficient amine grafting via pyrazole deprotonation and ion‐pair–stabilized hydrogen bonding with the pore walls. Spectroscopic analyses elucidate the interaction, while breakthrough experiments confirm the material's performance and cyclability.

CO chemisorption on Ir(111) [PDF]

, 1976
The adsorption of carbon monoxide on the (111) crystallographic orientation of iridium both at and below room temperature has been investigated using both low‐energy electron diffraction (LEED) and thermal desorption mass spectrometry.

A general and green approach of pH‐sensitive ZIF‐67 for encapsulating active substances

Smart Molecules, EarlyView.
Zeolitic imidazolate framework‐67 (ZIF‐67) was successfully synthesized in deionized water for 2 h in this work; meanwhile, various active substances could be encapsulated in one‐pot with the same process, resulting in high loading rates. The study delved into the growth mechanism, morphological difference and loading capacity.

Sorption Isotherm Curves in Dry Extruded Pet Foods: Evaluation and Comparison With the Drying Curve

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Sorption isotherms evaluate water exchange between food and environments with different water activities (aw), providing valuable information on physical changes and susceptibility of deterioration due to lipid oxidation and microbial growth.
