A composite includes a polymer; and a phase-change composition including an unencapsulated first phase-change material, and an encapsulated second phase-change material.

Biomedical devices for implantation with decreased pericapsular fibrotic overgrowth are disclosed. The device includes biocompatible materials and has specific characteristics that allow the device to elicit less of a fibrotic reaction after implantation than the same device lacking one or more of these characteristic that are present on the device. Biocompatible hydrogel capsules encapsulating mammalian cells having a diameter of greater than 1 mm, and optionally a cell free core, are disclosed which have reduced fibrotic overgrowth after implantation in a subject. Methods of treating a disease in a subject are also disclosed that involve administering a therapeutically effective amount of the disclosed encapsulated cells to the subject.

Embodiments of the present technology may include a system for forming an emulsion. The system may include a coiled tube. The coiled tube may have a first end and a second end. The second end may be located at a position higher than the position of the first end. The system may also include a plurality of beads disposed within the coiled tube. The system may further include a first inlet fluidly connected to the coiled tube. The first inlet may be configured to deliver a first fluid to the first end before the second end. In addition, the system may include a second inlet fluidly connected to the coiled tube. The second inlet may be configured to deliver a second fluid to the first end before the second end.

An object of the present invention is to increase an amount of a powder component dispersed in a content in a seamless capsule. The present invention relates to a seamless capsule including a content and an outer shell enclosing the content adjacently to the content, and provides a powder component-containing seamless capsule in which the content is a suspension prepared by dispersing a powder component, which is poorly soluble in water and oil, in an oil component or a hydrophilic component, the content has a specific gravity of 1 or more, and a difference (d=d.sub.Bd.sub.A) between the specific gravity (d.sub.A) of the content and a specific gravity (d.sub.B) of the outer shell is within the range of 0.15 to +0.05 and a method for manufacturing the same.

A method for manufacturing a capsule, said method comprising: preparing a mixture by mixing an aqueous solution of a hydrophilic high-molecular gelling agent, said aqueous solution containing at least one member selected from the group consisting of carrageenan, agar, sodium alginate and gellan gum, with an amphiphilic substance compatible with oil and water; adding a cation to the mixture; and removing the amphiphilic substance therefrom.

The present application provides for water capsules, preparation methods of water capsules, a preparation method for lightweight concrete and a structure of lightweight concrete. Each of the water capsules comprises an alkali-sensitive shell and water inside; the water capsules are used to mix with a cementitious matrix, the water capsules can survive during concrete mixing and transportation processes but then gradually rupture in hardened concrete; the water released during the hardening of the concrete is beneficial for the hydration of the concrete. The water capsules and their preparation method, the preparation method for and structure of the lightweight concrete of the present application are of unique design and strong practicability.

Capsules contain in their interior a water-based substance, and are coated with a film of alginate of an alkaline earth metal selected from calcium and magnesium. The capsules are of a larger size than previous capsules, while maintaining their sphericality. The capsules of water-based substances are obtained by incubating the capsules in suspension.

The present invention relates to a compound thickener comprising rhamsan gum and gellan gum. In the compound thickener, rhamsan gum accounts for 50%-95% of the total weight of rhamsan gum and gellan gum. The combination of rhamsan gum and gellan gum in the compound thickener produces a synergistic effect, and its viscosity is remarkably improved. The compound thickener can be applied to products such as foods, beverages, pharmaceutical products, and personal care products, and when the compound thickener is applied as a gelling agent in soft capsule shells, the shell strength and the shell elasticity are better.

A composition including a particle including a crosslinked matrix, prepared from a liquid droplet including a formulation including a polymer, the gelled particle having an average diameter of less than 250 pm, is provided herein. A method of printing the composition including releasing the liquid droplet into a fluid including an aerosol including a crosslinking agent and contacting the liquid droplet with the fluid is further provided. A device configured to introduce an aerosol including a crosslinking agent to a droplet of a formulation including a polymer as the droplet passes through the aerosol including the crosslinking agent is further provided.

This device comprises a hollow body, the hollow body defining: an internal conduit for distributing the first fluid, the internal conduit defining an inner volume; an external conduit or distributing the second fluid, the internal conduit and the external conduit extending coaxially along a longitudinal axis (AA). It at least comprises one metal tube extending along the longitudinal axis (AA) and being positioned in the inner volume of the internal conduit and/or in the downstream extension of the internal conduit and/or of the external conduit.
