Hypothesis: In a porous medium saturated with oil (containing oleic surfactant) and saline water, salinity reduction alters the thermodynamic equilibrium and induces spatial redistribution of surfactants, changing the local fluid configuration. During fluid-fluid displacement, this local change reshapes global fluid flows, and thus results in improved oil displacement.

Experiments: We performed microfluidic experiments in a centimeter-long pore-network model with a fracture and a dead-end model to observe both the macroscale flows and microscopic fluid configuration evolution.

Article Synopsis
  • The study explores the use of donor lungs from extended criteria after brain death (DBD) within the context of controlled donation after circulatory death (cDCD) lung transplants.
  • It involves a retrospective chart review from a hospital to compare outcomes between standard and extended criteria donor lungs over a six-year period.
  • Results indicate that using extended criteria lungs does not negatively impact lung transplant outcomes, including graft dysfunction rates and survival, suggesting a potential increase in available donor organs.
