Abstract: The invention relates to a method to prepare pockets comprising encapsulated material. The pockets are formed by first forming one or more bases B of barrier material on a substrate, by subsequently applying core material on at least part of the bases B and by forming a lid L on bases B provided with core material. The core material comprises at least one photoemissive particle or photoemissive compound such as quantum dots. The invention also relates to a pocket or a plurality of pockets comprising encapsulated material obtained by such method, to a device comprising at least one pocket of encapsulating material and to a process to transfer such a pocket of encapsulated material from one substrate to another substrate.

Abstract: Provided are compositions that may be referred to as photoreactive compositions or inks. The compositions may have a plurality of reactive components, which are silica nanocages with one or more photoreactive ligand(s). Also provided are methods of making an article of manufacture. Also provided are articles of manufacture and uses thereof. The article of manufacture may be formed from a composition of the present disclosure.

Abstract: Porous compositions and methods of making and using same. The compositions may be one or more layer(s) of mesoporous inorganic materials. The mesoporous inorganic material(s) may be a plurality of inorganic nanocages, which may be microporous. A composition may include homostacks of layers of the same inorganic mesoporous materials. A composition may include heterostacks of layers of inorganic mesoporous materials, where at least two of the layers are different. The compositions may be surface functionalized. The compositions may be formed in a reaction mixture including one or more precursor(s), one or more surfactant(s), water, and one or more organic solvent(s). The compositions may be formed at the liquid-liquid interface between the water and the one or more organic solvent(s). A composition may be used as a catalyst, in a catalytic method, as a separation medium, in a separation method, in nanomedicine applications, or the like.

Abstract: Provided are inorganic nanocages. The inorganic nanocages may be non-metal nanocages, transition metal oxide nanocages, or transition metal nanocages. Non-metal nanocages may include metal oxides. The inorganic nanocages can be made using micelles formed using pore expander molecules. The inorganic nanocages may be used as catalysts, drug delivery agents, diagnostic agents, therapeutic agents, and theranostic agents.
