The present application discloses an eco-friendly long-lasting heat-sensitive paper, including a substrate layer, a base color layer, a heat-sensitive covering layer, and a protective layer that are arranged sequentially from bottom to top, where the heat-sensitive covering layer is prepared as follows: coating a heat-sensitive covering layer raw material on the base color layer, and oven-drying a resulting product, where the heat-sensitive covering layer raw material is an emulsion obtained by mixing an acrylic hollow microsphere with a host resin. In the present application, an acrylic hollow microsphere that can change from an opaque state to a transparent state after rupturing under heat is used as a heat-sensitive covering layer to cover a base color layer to obtain the heat-sensitive paper with heat-sensitive color development characteristics.

The present disclosure provides curable compositions comprising polymerization inhibitor-functionalized particles to prevent undesired polymerization of the polymerizable compounds in the curable compositions during their transportation, handling or storage, or during 3D printing processes. Such curable compositions can be used to produce polymeric materials with properties suitable for use in various 3D printed objects, such as orthodontic appliances.

A coated pigment is used which includes a base of which at least the surface is composed of a light-transmitting material; and a magnetite layer coating the base, and having a crystal lattice constant of not less than 8.35 . At least one selected from the group consisting of silica, alumina, glass, mica and a resin is usable as the light-transmitting material.

A method of manufacturing an inorganic oxide nanofiber of an embodiment of the disclosure includes: preparing a mixture solution by dissolving water, a metal alkoxide, a catalyst, and a surfactant in an aprotic or protic polar solvent; removing the polar solvent from the mixture solution and synthesizing a nanostructure having a reverse two-dimensional hexagonal structure; and thereafter decomposing the nanostructure.

Silica nanoparticles grafted with hydrophobic branches and amines may be used to mitigate corrosion. For example, method for mitigating corrosion downhole may include introducing a treatment fluid into a subterranean formation, wherein the treatment fluid includes: an aqueous acid and a plurality of silica nanoparticles grafted with hydrophobic branches and amines. Examples of amines may include C2 to C18 amines. Examples of hydrophobic branches may include C2 to C18 alkyl groups.

The present disclosure concerns particulate matter including insoluble, non-magnetic, inorganic oxide particles, having, on each particle's surface, a plurality of, covalently grafted, ricinoleate compounds. The particulate matter is particularly suitable for odor scavenging of heterogenous materials. Further, the present disclosure provides a method of producing the particulate matter, articles of manufacture comprising the particulate matter and methods of producing the particulate matter.
