Summary: Microplastics have been found in drinking water, posing a risk to water quality by absorbing humic acid. This study investigated the behavior and mechanism of removing these microplastics and microplastics-humic acid compounds using coagulation-ultrafiltration technology. The results showed that aluminum-based salt was more efficient in removing both polystyrene and humic acid, and the optimal dosage for the composite system was higher than that for individual systems. The study also identified the main binding sites and weakening effects of various mechanisms during coagulation, as well as the alleviating effects of a formed cake layer and the presence of humic acid on membrane fouling. Overall, this research provides guidance for improving traditional drinking water treatment processes to remove microplastics.

Summary: The study developed a microfluidic device as an in vitro model for physiological confinement environments to investigate the role of vimentin in cell migration. Knockdown of vimentin was found to decrease cell migration speed and alter leading edge morphology under confinement, suggesting vimentin's impact on cytoskeletal organization and focal adhesion. This new approach using microfluidic devices integrated with time-lapse microscopy offers insights into the effects of vimentin on cell adhesion, migration, and invasiveness.
