A microcapsule, in particular of spherical shape, having a hollow capsule core encased by a capsule shell, characterized in that the capsule shell is at least partially made of hydrated cementitious material. A method for the production of a microcapsule includes the steps of: a) preparing of a suspension of particulate cementitious material in a solvent b) preparing a dispersion by mixing the suspension of step a) with an immiscible fluid so that (i) the suspension is present as a dispersed phase in the fluid as a dispersion medium or that (ii) the fluid is present as the dispersed phase in the suspension as the dispersion medium, such that the particulate material of the suspension adsorbs at least partially at a phase boundary between the fluid and the suspension, and c) allowing the particulate material adsorbed at the phase boundary to hydrate with the formation of an individual microcapsule.

In one aspect, radioactive nanoparticles are described herein.

The present specification discloses porogen compositions comprising a core material and shell material, methods of making such porogen compositions, methods of forming such porous materials using such porogen compositions, biocompatible implantable devices comprising such porous materials, and methods of making such biocompatible implantable devices.

A method of producing nanoparticles comprises effecting conversion of a molecular cluster compound to the material of the nanoparticles. The molecular cluster compound comprises a first ion and a second ion to be incorporated into the growing nanoparticles. The conversion can be effected in the presence of a second molecular cluster compound comprising a third ion and a fourth ion to be incorporated into the growing nanoparticles, under conditions permitting seeding and growth of the nanoparticles via consumption of a first molecular cluster compound.

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.

A decorative sheet including a substrate layer, and one or more layers of at least one of a transparent resin layer and a top coat layer provided on one surface of the substrate layer, the one or more layers being provided as a front surface layer, wherein at least one layer of the transparent resin layer and the top coat layer contains a radical scavenger, and the radical scavenger is contained in a form of radical scavenger vesicles, which encapsulate the radical scavenger within an outer membrane.
