Mathematical Modeling and Numerical Simulation of CO2 Removal by Using Hollow Fiber Membrane Contactors [PDF]

Iranian Journal of Oil & Gas Science and Technology, 2017
In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the ...

The influence of acoustic power on chemical absorption of CO2 using Slow Kinetic Solvent [PDF]

E3S Web of Conferences, 2021
Ultrasonic Irradiation (UI) is an emerging technology that is used to assist the CO2 absorption process. Even for the slow kinetic solvents without using any chemical promoter, high-frequency UI might enhance mass transfer during the absorption process ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
