Ralaxation of deformed drops, vesicles, and cells
The deformation of drops, vesicles, and cells constitutes an important class of problems in chemical and biomedical engineering and is often explored as a means to study interfacial dynamics and mechanical properties of the lipid membrane. Less attention has been paid to the relaxation process after the deforming mechanism is removed. In this study, analyses of such process are presented. A dro...
متن کاملDrops, Slugs, and Flooding in Polymer Electrolyte Membrane Fuel Cells
The process of flooding has been examined with a single-channel fuel cell that permits direct observation of liquid water motion and local current density. As product water flows through the largest pores in the hydrophobic GDL, drops detach from the surface, aggregate, and form slugs. Flooding in polymer electrolyte membrane (PEM) fuel cells occurs when liquid water slugs accumulate in the gas...
متن کاملBiocompatibility of fluids for multiphase drops-in-drops microfluidics
This paper addresses the biocompatibility of fluids and surfactants in the context of microfluidics and more specifically in a drops-in-drops system for mammalian cell based drug screening. In the drops-in-drops approach, three immiscible fluids are used to manipulate the flow of aqueous microliter-sized drops; it enables merging of drops containing cells with drops containing drugs within a Te...
متن کاملControlled encapsulation of single-cells into monodisperse picolitre drops.
Encapsulation of cells within picolitre-size monodisperse drops provides new means to perform quantitative biological studies on a single-cell basis for large cell populations. Variability in the number of cells per drop due to stochastic cell loading is a major barrier to these techniques. We overcome this limitation by evenly spacing cells as they travel within a high aspect-ratio microchanne...
