Interfacial mechanisms governing rarefied gas transport in nanochannels: molecular insights beyond Knudsen theory

Lian Duan, Minjunshi Xie, Jun Zhang, Jing Liu et autres

Rarefied gas transport in nanoporous media governs key processes in gas capture and separation, yet classical Knudsen theory neglects the molecular nature of gas–surface interactions. Using molecular dynamics simulations, we investigate the diffusion of rarefied CO 2 and propane (C 3 ), …

Molecular insight into interfacial structure-driven anisotropic CO2 diffusion in water-saturated silica confinements

Minjunshi Xie, Lian Duan, Xu Liu, Zhehui Jin

• Anisotropic CO 2 transport emerges on Q3 surfaces under hydrated confinement. • Directional CO 2 diffusion follows corridor-like arrangements of adsorption sites. • Interfacial structure governs nanoscale CO 2 transport behavior. • Residence time is related to surface wettability.

Study of the Influence of Na + and Mg 2+ on CaCO 3 Cluster Nucleation and Growth Based on ReaxFF Molecular Dynamics Simulations

Qian Chen, Bei Wei, Jian Hou, Yongge Liu et autres

Understanding the nucleation and growth mechanisms of calcium carbonate (CaCO 3 ) in multicomponent aqueous environments is essential for regulating mineralization. Here, ReaxFF molecular dynamics simulations were employed to investigate the effects of Na + and Mg 2+ on CaCO 3 cluster …

Interfacial water structure effect on CO2 solubility in water-saturated silica confinements: A molecular perspective

Minjunshi Xie, Mingshan Zhang, Lian Duan, Wenting Xiong et autres

Hypothesis Solubility trapping is a key mechanism in geological carbon sequestration (GCS), yet CO 2 solubility in water-filled nanopores often deviates markedly from bulk behavior. We hypothesize that variations in CO 2 solubility within silica nanopores originate from differences in interfacial water …

Drastic-yet-distinct alterations in rarefied gas transport of CO2 and propane in nanochannels by finely-tuning surface characteristics

Lian Duan, Zhehui Jin

• Under ambient conditions in nanochannels, CO 2 self-diffusivity is only half of that of propane, against the Knudsen theory. • Finely-tuning surface properties boosts CO 2 self-diffusivities by ∼ 290 % versus ∼ 35 % for propane. • The distinct alteration …

Water-Lubricated CO2 and CH4 Transport in Crystalline Silica Mesopores: A Molecular Dynamics Study

Lian Duan, Zhehui Jin

In this study, we use molecular dynamics simulation to study slippage behaviors of pressure-driven CO 2 and CH 4 flows with water films in β-cristobalite mesopores. Significant differences in water-induced enhancement in gas slippage are observed in comparison to pure CO 2 …

Effects of Interfacial Molecular Structures on Pressure-Driven Brine Flow in Silica Mesopores

Lian Duan, Mingshan Zhang, Yiling Nan, Zhehui Jin

In this work, we conduct molecular dynamics simulations to investigate pressure-driven brine flow in silica mesopores under typical reservoir conditions (323 K and 20 MPa). While surface counterions accumulate strongly in the vicinity of fully deprotonated silica surfaces, water forms multilayer structures …

Periodontitis Deteriorates Cognitive Function and Impairs Neurons and Glia in a Mouse Model of Alzheimer’s Disease

Xueshen Qian, Shuang Zhang, Lian Duan, Feng‐Chun Yang et autres

Background: Although periodontitis is reportedly associated with increased cognitive decline in Alzheimer’s disease, the mechanisms underlying this process remain unknown. Porphyromonas gingivalis lipopolysaccharide (P.g-LPS) is an endotoxin associated with periodontal disease. Objective: We investigated the effect of periodontitis on learning capacity and …

A method for pore-scale simulation of single-phase shale oil flow based on three-dimensional digital cores with hybrid mineral phases

Lian Duan, Hai Xia Sun, Lei Zhang, Zhehui Jin et autres

The mineral properties of the pore walls have a great influence on the single-phase shale oil flow at the pore scale. In this paper, a new method is proposed for pore-scale simulation of single-phase shale oil flow based on digital cores with …
