The present invention generally relates to emulsions, and more particularly, to multiple emulsions. In one aspect, multiple emulsions are formed using a plurality of channels, such as microfluidic channels, that meet at a common intersection. The multiple emulsions may be created at a single common intersection in some embodiments, unlike other prior art systems where multiple channel intersections are required to create multiple emulsions. For instance, in one set of embodiments, three, four, or more microfluidic channels may intersect at a common intersection, with two or three serving as inlets and one serving as the outlet. In some embodiments, a first fluidic channel may be relatively hydrophobic, while a second fluidic channel is relatively hydrophilic. The third channel, if present, may be relatively hydrophilic or hydrophobic, depending on the application. The outlet channel may be hydrophobic, hydrophilic, or may comprise at least one portion that is relatively hydrophilic and at least one portion that is relatively hydrophilic. By controlling the flow of fluids through the hydrophilic and hydrophobic portions of the channels, multiple emulsions may be created proximate the common intersection, due to interactions between the fluids entering the common intersection. In other embodiments, different patterns of hydrophilic or hydrophobic channels may be used. Other aspects of the invention are generally directed to methods of making and using such systems, kits involving such systems, emulsions created using such systems, or the like.

Parallel uses of microfluidic methods and devices for focusing and/or forming discontinuous sections of similar or dissimilar size in a fluid are described. In some aspects, the present invention relates generally to flow-focusing-type technology, and also to microfluidics, and more particularly parallel use of microfluidic systems arranged to control a dispersed phase within a dispersant, and the size, and size distribution, of a dispersed phase in a multi-phase fluid system, and systems for delivery of fluid components to multiple such devices.

A variable transmission film may include an electrophoretic medium having a plurality of capsules and a binder, each capsule containing a plurality of electrically charged particles and a fluid, the charged particles being movable by application of an electric field and being capable of being switched between an open state and a closed state. The film may include at least one of a binder containing fish gelatin and a polyanion; a binder containing one or more tinting agents; capsules containing charge control agents, such as an oligoamine-terminated polyolefin and a branched chain fatty acid comprising at least 8 carbon atoms; a selection of capsules in which at least 60% have a diameter between 50 μm and 90 μm and at least 15% have a diameter between 20 μm and 49 μm; a tinted adhesive layer; and a fluid selected from one or more nonconjugated olefinic hydrocarbons.

An electro-optic media includes either a plurality of microcapsules in a binder, a polymeric sheet containing sealed microcells, or droplets in a continuous polymeric phase. Each of the microcapsules, microcells, or droplets contain a dispersion that includes a plurality of charged composite particles and a suspending fluid, and the charged particles move through the suspending fluid under the influence of an electric field. The composite particles include one or more types of pigment particles that are at least partially coated with a polymeric material. Each of the binder, polymeric sheet, continuous polymeric phase, the charged composite particles, and the suspending fluid have an index of refraction, and a difference between the index of refraction of the composite particles and at least one of the binder, polymeric sheet, continuous polymeric phase, and solvent is less than or equal to 0.05 at 550 nm.
