Spherical boron powders with sizes ranging from 4 to 100 μm were prepared by ball milling a commercial powder. A planetary mill was used process control agent consisting of two immiscible fluids: hexane and acetonitrile. The spherical formed when the volume loaded close that acetonitrile in presence excess hexane. Particle measured using low-angle laser light scattering, they examined scanning ...

By combining interfacial nanoparticles and molecular surfactants together with immiscible liquids of high viscosity, we develop an alternative strategy for creating bicontinuous interfacially jammed emulsion gels (bijels). These bijels are prepared from common ingredients which are widely used in industry: glycerol, silicone oil, silica nanoparticles together with cetyltrimethylammonium bromide...

Interfacial Tension In article number 2100129, Gregor Pirnat and Matjaž Humar demonstrate a simple, fast, very precise technique to measure time dependent interfacial tension between two immiscible liquids based on whispering gallery modes in micrometer droplets. The optical enable measurements of the droplet size as well refractive index one fluids.

Impact of drops on the surface of an immiscible liquid is studied. We show that in addition to the commonly-observed lens structure at the air-liquid interface, drops released from critical heights above the target liquid can sustain the impact and at the end maintain a spherical ball-shape configuration above the surface despite undergoing large deformation. The existence of this metastable st...

Electrostatic fiber formation (“electrospinning”) is the leading technology for production of continuous fibers with submicron diameter. Applications such as drug delivery and sensors benefit from the ability to produce submicron fibers with a core/shell morphology from electrified coaxial jets of two liquids. However, low productivity of the conventional needlebased coaxial process is a barrie...

We propose and demonstrate a novel liquid deformable mirror, based on electrocapillary actuation, for high-order wavefront correction. The device consists of a two-dimensional array of vertically oriented microchannels filled with two immiscible liquids, an aqueous electrolyte, and a viscous dielectric liquid, where the dielectric liquid overfills the top end of the channel and forms a thin lay...
