Abstract: Embodiments disclosed herein are hemp wood preservative compositions, and related methods. A composition for treating wood includes a methyl ester composition, hemp seed oil (HSO), wax present in an amount of about 10 wt % or less of the composition, and silica present in an amount of about 10 wt % or less of the composition. A method of forming a composition for treating wood includes forming a mixture including wax and a methyl ester composition, mixing hemp seed oil with the mixture including the wax and the methyl ester composition, and mixing silica with at least one of (1) the mixture including the wax and the methyl ester composition, (2) the hemp seed oil, and/or (3) the hemp seed oil with the mixture including the wax and the methyl ester composition.

Abstract: The present invention relates to mesoporous silica coated nanoparticles comprising a metal oxide nanoparticle core; and a mesoporous silica shell encapsulating metal oxide core; wherein said mesoporous silica shell and the metal oxide core are not in full contact. The nanoparticles of the invention are useful as diagnostic and therapeutic agents.

Abstract: Silica particles, and methods of making and using silica particles are disclosed herein. In some embodiments, the silica particles are hollow, include an outer shell portion having a mesoporous structure, and have a pore volume of at least 4 cm3/g. In some embodiments, the silica particles include an outer shell portion having a mesoporous structure forming a cavity, the silica particles have an average pore diameter of 3 to 100 nm, and at least a portion of the silica particles include one or more core nanoparticles within the cavity. Silica particles as disclosed herein can be useful in a wide variety of applications such as selective separations (e.g., gas separations or purifications) based on structure.
