PSRC Abstract Supplement P oter P rofs gel concentrations. Mechanical tests were carried out with an indentation test, and the deformation distance of the gel construct was used as an indicator of relative gel stiffness. A total of 5 different concentrations were used with relative stiffness including: <1, 5, 9, 18 and 25 kPa. The 3D gels were cultured as a single droplet on a 48-well suspensio...

Quantitative application of digital in-line holography (DIH) to characterize multiphase fragmentation is demonstrated. DIH is applied to record sequential holograms of the breakup of an ethanol droplet in an aerodynamic flow field. Various stages of the breakup process are recorded, including deformation, bag growth, bag breakup, and rim breakup. A recently proposed hybrid method is applied to ...

We use droplet microfluidics to produce monodisperse elastomeric microbubbles consisting of gas encapsulated in a polydimethylsiloxane shell. These microbubbles withstand large, repeated deformations without rupture. We perform μN-scale compression tests on individual microbubbles and find their response to be highly dependent on the shell permeability; during deformation, the pressure inside i...

We present new algorithms for simulating pressuregradient flows in molecular dynamics (MD) simulations. Nano-channel inlet and outlet non-periodic boundary conditions are implemented using hydrodynamic statereservoirs and flux boundary models at arbitrary boundaries of the domain geometry. We demonstrate the new method in a complex nano-mixer configuration and for droplet deformation in extensi...

The breakup of non-Newtonian droplets is ubiquitous in numerous applications. Although the property can significantly change droplet process, most previous studies consider Newtonian droplets, and effects properties on process are still unclear. This study focuses secondary shear-thinning by numerical simulation. volume fluid method used to capture interface dynamics adaptive grids. To compare ...
