Abstract: The invention relates to a method of making hybrid organic-inorganic core-shell nano-particles, comprising the steps of a) providing colloidal organic particles comprising a synthetic polyampholyte as a template; b) adding at least one inorganic oxide precursor; and c) forming a shell layer from the precursor on the template to result in core-shell nano-particles. With this method it is possible to make colloidal organic template particles having an average particle size in the range of 10 to 300 nm; which size can be controlled by the comonomer composition of the polyampholyte, and/or by selecting dispersion conditions.
The invention also relates to organic-inorganic or hollow-inorganic core-shell nano-particles obtained with this method, to compositions comprising such nano-particles, to different uses of said nano-particles and compositions, and to products comprising or made from said nano-particles and compositions, including anti-reflective coatings and composite materials.

Abstract: An ultra low density film and an ultra low density solid material are produced by the steps of providing a vessel, introducing two immiscible fluids into the vessel, adding nanocrystals to at least one of the two immiscible fluids, applying a shear force to the two immiscible fluids and the nanocrystals in a manner that causes the nanocrystals to self-assemble and form colloidosomes. The colloidosomes amass and evaporation of the two fluids produces dried colloidosomes. The ultra low density self-assembled colloidosomes are hollow self-assembled colloidosomes, which are formed into the ultra-low density film and the ultra-low density solid.

Abstract: A process for forming an extruded composition using a wet-spin dry-jet technique including forming a dispersion dope by mixing phase change material with a first portion of solvent, and sonicating the mixture, forming a prime dope by combining a first portion of polymer and a second portion of solvent, forming an extrusion composition by combining the dispersion dope, the prime dope and a second portion of the polymer, rolling the extrusion composition, degassing the extrusion composition, extruding the extrusion composition through a spinneret, drying the extruded composition, and quenching the extruded composition. The weight fraction of the phase change material in the extruded composition can be greater than approximately 60%, and preferably greater than approximately 75%.

Abstract: Droplet generation devices and systems that parallelize droplet generation devices are provided. The droplet generation devices can include a symmetric block-and-break system and a tapered droplet generation zone. The symmetric block-and-break system can include a pair of break channels and a pair of bypass channels symmetrically arranged with respect to the dispersed-phase input channel and the output channel. The droplet generation devices can generate monodisperse droplets with a predefined volume over a range of flow rates, pressures, and fluid properties. The droplet generation devices are therefore capable of parallelization to achieve large-capacity droplet generation, e.g. greater than 1 L/hr, with small overall coefficients of variation.

Abstract: This invention relates to a process for colloidosome-type microcapsules elaboration from solid particles microcapsules obtained by ionic gelation. In the process, an (O/W) type emulsion is initially generated stabilized with the solid particles microcapsules, and then the particles are fixed to the interface by adsorption of polyelectrolytes, cross-linking, heat treatment or fatty coating, generating the colloidosome with the water-insoluble phase encapsulated in the core and covered by the shell particles.

Abstract: The methods described herein, referred to as particle-templated emulsification (PTE), provide an improved approach for generating a monodisperse emulsion that encapsulates target particles of interest without requiring the use of a microfluidic device. Monodisperse droplets may be effectively obtained by using monodisperse particles to template the formation of droplets, which can include, e.g., monodisperse single-emulsion droplets, multiple-emulsion droplets, or Giant Unilamellar Vesicles (GUV), without destroying the integrity of the droplets.
