Migration characteristics and storage forms of liquid and supercritical CO2 in saline aquifers

open access: yesMeitian dizhi yu kantan
ObjectiveCO2 storage in saline aquifers serves as a critical technology used to dramatically reduce greenhouse gas emissions. Owing to the low-temperature marine environment and the pressure from overlying seawater, shallow offshore saline aquifers ...

Smart Bioinks for 4D Bioprinting: Requirements, Design, and Applications

open access: yesAdvanced Science, EarlyView.
Smart bioinks empower 4D‐bioprinted constructs to dynamically adapt and remodel in response to stimuli, effectively biomimicking native tissues. Artificial Intelligence (AI) and Machine Learning (ML) play a guiding role in their rational design by optimizing relevant properties.

Effect of supercritical CO2 on pore structure and desorption characteristics of tectonic coal

open access: yesMeikuang Anquan
In order to analyze the influence of supercritical CO2 on pore structure and desorption characteristics of tectonic coal, a high-temperature and high-pressure geological environment simulation system was used to treat primary coal and tectonic coal with ...

Permeation of supercritical CO2 through dense polymeric membranes

open access: yes, 2019
Supercritical carbon dioxide (scCO2) is used in the food industry as a water-extracting drying agent. Once saturated with water, the scCO2 needs to be regenerated. A promising way of drying scCO2 is by using H2O permeable membranes.

In Situ CO2‐Induced Hydrogels for Enhancing Carbon Sequestration in Saline Aquifers

open access: yesAdvanced Science, EarlyView.
A novel integrated method that combines in situ CO2‐induced phase‐transition hydrogels formed by a C22‐tailed tertiary amine dispersion with tailored deep eutectic solvents to increase CO2 sequestration in saline aquifers. ABSTRACT Carbon sequestration in saline aquifers underpins global net‑zero emission goals, yet existing CO2 storage capacity ...

Study on the mechanism of CO2 injection to improve tight sandstone gas recovery

open access: yesEnergy Reports, 2023
Supercritical CO2 can improve gas recovery and achieve carbon sequestration in tight gas reservoir. It is a hot topic but not applied extensively. The main restricts include the unclear mechanism of gas-to-gas displacement and the reduction of the ...

Microcellular Foaming of Polymethylmethacrylate in a Batch Supercritical CO2 Process: Effect of Microstructure on Compression Behavior [PDF]

open access: yes, 2010
Microcellular foaming of reinforced core/ shell Polymethylmethacrylate (PMMA) was carried out bymeans of supercritical CO2 in a single-step process. Samples were produced using a technique based on the saturation of the polymer under high pressure of CO2(

Experimental investigation of the mechanism of supercritical CO2 interaction with tight sandstone

open access: yesFrontiers in Energy Research, 2022
One of the important technologies for combating global climate change is CCUS (Carbon Capture, Utilization, and Storage), which aims to address the issue of “greenhouse effect” generated by a significant amount of greenhouse gas emissions.
