Aquaporins and CO2 diffusion across biological membrane [PDF]
Frontiers in Physiology, 2023 Despite the physiological significance of effective CO2 diffusion across biological membranes, the underlying mechanism behind this process is not yet resolved. Particularly debatable is the existence of CO2-permeable aquaporins.

Experimental study of the supercritical CO2 diffusion coefficient in porous media under reservoir conditions [PDF]
Royal Society Open Science, 2019 Reliable measurement of the CO2 diffusion coefficient in consolidated oil-saturated porous media is critical for the design and performance of CO2-enhanced oil recovery (EOR) and carbon capture and storage (CCS) projects.

Study on diffusion characteristics of CO2 in low permeability coal under sub-critical conditions
Meikuang Anquan, 2023 In order to study the diffusion characteristics of CO2 in low-permeability raw coal under subcritical conditions (gas pressure lower than 6 MPa and temperature lower than 39 ℃), the CO2 adsorption/desorption experiments and diffusion experiments were ...

Molecular dynamics simulation of CO2 dissolution-diffusion in multi-component crude oil
Frontiers in Environmental Science, 2023 In order to study the dissolution-diffusion process and mechanism of CO2 in multi-component crude oil, a model of multi-component crude oil system with octane as the main component and 16 other alkanes as a compound was constructed by using molecular ...

Study on CO2 adsorption and diffusion law of coal under different temperatures and pressures
Meikuang Anquan, 2023 In order to overcome the difficulty of gas mining when coal mining depth increased, the adsorption and diffusion laws of CO2 molecules at different temperatures and pressures were simulated by using the simulation software Materials Studio; the ...

Facilitated Diffusion of CO2 across Albumin Solutions [PDF]
The Journal of General Physiology, 1974 The steady-state CO2 flux across thin layers of 30 g/100 ml albumin solutions was measured in two different CO2 partial pressure ranges (boundary PCO2 values 3 and 8 torr, and 160 and 650 torr, respectively). From the data the apparent diffusion coefficient for CO2, DCO2, was calculated.
