Abstract: Two programmable masks are used for the exposure of three-dimensional patterns in a photosensitive material. This exposure technique takes advantages of symmetries and repeating structures in the exposure pattern to reduce the exposure time, while maintaining the flexibility to produce complicated three-dimensional shapes.

Abstract: The preparation of monodispersed TiO2 nanocrystals with nanocrystal size between 1-30 nm is described herein. These TiO2 nanocrystals are used to prepare dispersions into solvents, formulation into monomers, oligomers, and polymers, and nanocomposites from the resulting formulations. Dispersions of nanocrystals can be formed in various solvents at high loading, high transmittance, and low viscosity. Formulations incorporating these nanocrystals and a matrix material are highly stable, where the resulting nanocomposites have high refractive index and are optically transparent in the visible wavelengths, with very little or no scattering.

Abstract: Light-emitting devices and methods of making the same are described whereby lenses of any array include a material with a higher refractive index than an encapsulation layer of a substrate layer, the refractive index of the material being in a range of greater than 1.7 to 1.9 at 400 nm. The material forming the lenses includes nanocomposite comprised of inorganic nanocrystals and a polymeric matrix, wherein the nanocrystals are selected from the group consisting of ZrO2, ZnO, MgO, HfO2, NbO5, Ta2O5 and Y2O3. A 3-4 micron thick sample of the nanocomposite has an optical transmittance of at least 80% over a range of 440 nm to 800 nm.

Abstract: 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.

Abstract: 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 thews-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.
