Metal-oxide nanocrystals have applications in lubrication and electronics displays

By Scott Jenkins |

Pixelligent Technologies Inc. (Baltimore, Md.; www.pixelligent.com) has developed a process for making metal-oxide nanocrystaline materials that have found uses as additives in a variety of industrial lubricants, mixed- and augmented-reality (AR/MR) glasses, and various display technologies. The company’s PixClearProcess results in dispersions of zirconium dioxide (ZrO2) or titanium dioxide (TiO2) nanocrystals capped with surface agents. The 5-nm crystals (photo) are grown from the bottom up via a proprietary method. The nanocrystal cores are coupled with functional groups on their surfaces, according to the application. The surface functional groups prevent the particles from aggregating, allowing for uniform dispersions in various media, including oils, solvents and resins. “The PixClearProcess uses readily available raw materials and widely available equipment customized for Pixelligent to manufacture amounts of advanced nanocomposites in the range of several kilograms to multiple tons,” says Richard Ming, Pixelligent global sales and marketing director. The metal-oxide nanoparticles increase the refractive index (RI) of the resin into which they are added and enable larger fields of view in AR/MR glasses. In display applications,…
