A nanocomposite optical ceramic (NCOC) material includes a plurality of coated (core-shell) nanoparticles having nanoparticles of a first material coated with a coating of a second material. The first material and the second material are mutually insoluble and each have a transmissivity of at least 80% for an intended wavelength. The first material and the second material have a difference in index of refraction of less than 25%. The first material and second material have grins with a diameter of less than 1/20the intended wavelength. The coating of the second material on the nanoparticles of the first material is up to 50 nm thick. The NCOC contains no more than 0.01% voids per unit volume.

Coated (core-shell) nanoparticles for nanocomposite optical ceramics

A nanocomposite optical ceramic (NCOC) material. The material having a first solid phase, a second solid phase, and a third solid phase. The first solid phase has first solid phase grains no larger than 5 μm, and each first solid phase grain has a first solid phase grain boundary. The second solid phase has second solid phase grains no larger than 5 μm, and each second solid phase grain has a second solid phase grain boundary. The third solid phase has a doping agent. The doping agent is less than 5 atomic % soluble in the first solid phase and the second solid phase. At least part of the third solid phase is situated at the second solid phase grain boundary.

A method of bonding includes applying a glass composition to at least a first material surface. The glass composition includes a glass powder and a solvent. The first material surface is disposed onto a second material surface. An elevated temperature is applied to the first material surface and the second material surface to form a bond between the first material surface and the second material surface. The first material surface and the second material surface are compressed under an isostatic pressure.

A pillow for an infant includes a pillow body and a support member. The pillow body includes a medial portion and a pair of arms extending therefrom. Each of the arms includes a first end and a second end. The medial portion is formed integrally with, and extends generally laterally between, the arm first ends. The pair of arms are spaced apart in a mirrored relationship such that a well region is defined therebetween. The support member includes a body portion and a head portion extending from the body portion. The body portion extends across the well region and is between the pair of arms. The head portion is coupled to, and extends from, each of the arm second ends.
