CORE-SHELL PARTICLES AND USE THEREOF
In a method for manufacturing core-shell particles including core particles and a shell, the constituent metal elements of the core particles and the shell are different from each other. A quinone-containing core particle dispersion containing at least core particles consisting of a first metal, hydroquinone (HQ), benzoquinone (BQ), and a second metal compound including a second metal element for making up the shell is prepared, and a reduction treatment is performed on the quinone-containing core particle dispersion, through addition of a reducing agent, to form a shell including the second metal element as a main constituent element, on the surface of the core particles. A mass ratio: HQ/BQ ratio of added hydroquinone (HQ) and benzoquinone (BQ) is 0.1 to 120.
Method of encapsulating particulate material
A method of encapsulating particulate materials. The method of encapsulating particulate materials may be used to multi coat a coated thermoplastic particle. The method includes providing an amount of acidified water in an amount to hydrolyze a pre-determined amount of alkoxysilane. A particulate thermoplastic material is dispersed within the acidified water. Once dispersed, an amount of alkoxysilane having a pre-determined formula is added and an amount of time is allowed to pass thereby allowing the alkoxysilane to hydrolyze and build a particle having a pre-determined particle size. Once the particle with pre-determined particle size has been obtained, the particles may be combined with alkoxysilane having a pre-determined formula and an amount of time is allowed to pass thereby allowing the alkoxysilane to hydrolyze and build a particle having a pre-determined particle size. This provides an encapsulated particulate material having one or more coatings thereon.

Polyelectrolyte microcapsules and methods of making the same
Polyelectrolyte microcapsules, and methods for making and using the polyelectrolyte microcapsules, are described. A method of making polyelectrolyte microcapsules includes forming an “interfacial complexation in emulsion” (ICE), wherein a polyelectrolyte “shell” is formed by complexing two different polyelectrolytes together at an interface between two immiscible fluids. Both hydrophilic and hydrophobic materials can be incorporated into the cores and shells of the polyelectrolyte microcapsules.
