Provided are metal oxide ceramic materials and intermediate materials thereof (e.g., nanozirconia gels, nanozirconia green bodies, pre-sintered ceramic bodies, zirconia dental ceramic materials, and dental articles). The nanozirconia gels are formable gels. Also provided are methods of making and using the metal oxide materials and intermediate materials. The nanozirconia gels can be made using, for example, osmotic processing. The nanozirconia gels can be used to make nanozirconia green bodies, pre-sintered ceramic bodies, zirconia dental ceramic materials, and dental article. The nanozirconia green bodies, pre-sintered ceramic bodies, zirconia dental ceramic materials, and dental articles have desirable properties (e.g., optical properties and mechanical properties).

Metal oxide ceramic nanomaterials and methods of making and using same

At least partially capped nanocrystals and nanocomposites containing the nanocrystals are described herein along with products, uses and methods of making.

High refractive index solvent free silicone nanocomposites

The present disclosure provides nanocrystals(s) containing silicone capping agent(s). Dispersions containing the nanocrystal(s) and at least one of silicone monomer(s), silicone pre-polymer(s), and silicone polymer(s), and optionally additionally containing a solvent are also described. Cured dispersions, compositions of nanocrystal(s) and LEDs and related structures containing the composition(s) are provided in the present disclosure.

High refractive index silicone nanocomposites

Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on the as-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.

Synthesis, capping and dispersion of nanocrystals

The presently disclosed technology relates to a nano-additives to improve the performance of lubricants, oils, and greases. More specifically, the presently disclosed technology relates to applying capped metal oxide nanoparticles, such as capped zirconia nanoparticles, in the lubricants to produce a tribofilms on the lubricating surfaces to provide wear protection to the said surfaces. Also, the interaction of the capped zirconia nanoparticles with other commonly used additives in lubricants may further optimize the performance of the resulting tribofilms.

Nano-additives enabled advanced lubricants

The current disclosure relates to a nanocomposites coating including metal oxide nanocrystals, the nanocomposites further include a mixture of acrylates monomers and oligomers to provide a curable coating that provides high refractive index, high transmittance, and high temperature stability.
