Pore-scale evaluation of CO2 miscible displacement in porous rocks induced by convection and diffusion: implications for CO2 geo-sequestration

International Journal of Coal Science & Technology
CO2 enhanced oil recovery plays an important role in carbon storage and utilization. However, the incomplete understanding of the underlying microscopic convection–diffusion mechanisms in complex pore structures has constrained the broader industrial ...

Diffusion, mass transfer and oil mobilization mechanisms of CO2 huff-n-puff in Gulong shale oil reservoirs

Petroleum Exploration and Development
To reveal the complex crude oil-CO2 interaction mechanism and oil mobilization behavior during CO2 huff-n-puff in shale-type shale oil reservoirs, CO2 huff-n-puff experiments with on-line nuclear magnetic resonance monitoring were conducted on Gulong ...

Responses of leaf stomatal and mesophyll conductance to abiotic stress factors

Journal of Integrative Agriculture, 2022
Plant photosynthesis assimilates CO2 from the atmosphere, and CO2 diffusion efficiency is mainly constrained by stomatal and mesophyll resistance. The stomatal and mesophyll conductance of plants are sensitive to abiotic stress factors, which affect the ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

FEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Enzymatic and microbial routes to bioplastics: The green chemistry frontier of biopolymers

FEBS Open Bio, EarlyView.
Microbial biosynthesis and engineered enzyme platforms are expanding the design space of polyhydroxyalkanoate bioplastics. By combining fermentation, PHA synthase engineering and cell‐free modular systems, tailored biodegradable polymers can be produced with tunable properties, supporting more sustainable materials and future circular bioeconomy ...

Molecular simulation of self-diffusion of CH4, H2O and CO2 in coal macromolecule

Meikuang Anquan
In this paper, the self-diffusion coefficients (SDC) of CH4/CO2/H2O in coal molecules under different ensemble conditions and the effects of temperature and pressure are calculated by grand canonical Monte Carlo and molecular dynamics (MD) methods ...

SELECTIVITY AND SELF DIFFUSION OF CO2 AND H2 IN A MIXTURE ON A GRAPHITE SURFACE

Frontiers in Chemistry, 2013
We performed classical molecular dynamics (MD) simulations to understand the mechanism of adsorption from a gas mixture of CO2 and H2 (mole fraction of CO2 = 0.30) and diffusion along a graphite surface, with the aim to help enrich industrial off-gases ...

Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...

Inversely estimating the vertical profile of the soil CO2 production rate in a deciduous broadleaf forest using a particle filtering method.

PLoS ONE, 2015
Carbon dioxide (CO2) efflux from the soil surface, which is a major source of CO2 from terrestrial ecosystems, represents the total CO2 production at all soil depths.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.
