A template-assisted method for the synthesis of 2D nanosheets comprises growing a 2D material on the surface of a nanoparticle substrate that acts as a template for nanosheet growth. The 2D nanosheets may then be released from the template surface, e.g. via chemical intercalation and exfoliation, purified, and the templates may be reused.

An alkali-free H-AFX zeolite and synthesis procedure are disclosed, as well the use of such zeolite as a catalyst in an SCR process.

The present disclosure provides functionalized powder particles and methods of forming functionalized powder particles. The functionalization is acquired through the formation of primary and/or secondary structures on a powder particle. Functionalization can be controlled to bring about changes in a broad range of physical and/or chemical properties.

Monodisperse particles having: a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology are disclosed. Due to their uniform size and shape, the monodisperse particles self assemble into superlattices. The particles may be luminescent particles such as down-converting phosphor particles and up-converting phosphors. The monodisperse particles of the invention have a rare earth-containing lattice which in one embodiment may be an yttrium-containing lattice or in another may be a lanthanide-containing lattice. The monodisperse particles may have different optical properties based on their composition, their size, and/or their morphology (or shape). Also disclosed is a combination of at least two types of monodisperse particles, where each type is a plurality of monodisperse particles having a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology; and where the types of monodisperse particles differ from one another by composition, by size, or by morphology. In a preferred embodiment, the types of monodisperse particles have the same composition but different morphologies. Methods of making and methods of using the monodisperse particles are disclosed.

The present invention provides a process for depositing an oxide coating on an inorganic substrate, including providing an aqueous composition containing a tetraalkylammonium polyoxoanion and hydrogen peroxide; contacting the aqueous composition with an inorganic substrate for a time sufficient to deposit a hydroxide derived from the polyoxoanion on surfaces of the inorganic substrate to form an initially coated inorganic substrate; and heating the initially coated inorganic substrate for a time sufficient to convert the hydroxide to an oxide to form on the inorganic substrate an oxide coating derived from the polyoxoanion. The inorganic substrate may be a ceramic material or a semiconductor material, a glass or other dielectric material, and the ceramic material may be a lithium ion battery cathode material.

The present disclosure relates to a coating composition comprising calcium silicate and precipitated calcium carbonate particulate material, a suspension comprising the coating composition and at least one solvent, an article which is at least partially coated with the coating composition or the suspension, and a process for producing an article, wherein the article is at least partially coated with the suspension, and use of the coating composition comprising calcium silicate and precipitated calcium carbonate particulate material.

Methods of synthesizing MOF materials are disclosed. Further, plasmonic MOF composites and uses thereof as a recyclable catalyst, for ultrafast desorption (e.g., of solvents), MOF activation are also disclosed.

A biconical tungsten (molybdenum) trioxide powder, and a preparation method and use thereof are provided. By adjusting the concentrations of glycerol and oxalic acid, the viscosity of the reaction solution could be adjusted, and then the growth of a (001) crystal plane and a (110) crystal plane of the tungsten (molybdenum) trioxide powder could be inhibited; thus, a monodisperse biconical tungsten (molybdenum) trioxide powder could be controllably prepared with a highly exposed (100) crystal plane.
