Interfacial Tension-Temperature-Pressure-Salinity Relationship for the Hydrogen-Brine System under Reservoir Conditions: Integration of Molecular Dynamics and Machine Learning.

Hydrogen (H) underground storage has attracted considerable attention as a potentially efficient strategy for the large-scale storage of H. Nevertheless, successful execution and long-term storage and withdrawal of H necessitate a thorough understanding of the physical and chemical properties of H in contact with the resident fluids. As capillary forces control H migration and trapping in a subsurface environment, quantifying the interfacial tension (IFT) between H and the resident fluids in the subsurface is important.

Molecular insight into COF monolayers for urea sorption in artificial kidneys.

Urea removal from an aqueous solution is considered a challenge in the biological process. The state of complete kidney destruction is known as an end-stage renal disease (ESRD). Kidney transplant and hemodialysis are the most common methods for confronting ESRD.
