    摘要: Stable, translucent or transparent titanium dioxide sols comprising amorphous titanium dioxide and an organic peptizing agent are provided that are useful in particulate binding applications. Also provided are methods for preparing the inventive sols. The inventive sols are prepared from titanium dioxide precursors including organotitanium compounds and water-soluble titanium salts that are treated to precipitate amorphous titanium dioxide. The amorphous titanium dioxide is re-dispersed and peptized to form a translucent or transparent mixture. The inventive sols are stable for an extended period of time.

    摘要: An off page condition or invalid sensors position data is detected by checking the errors from an initial transformation parameter estimation. If an abnormally large error is encountered, a sensor's reading (position data) may be invalid or the sensor was off page. Then the invalid sensor data will be identified and removed. Finally the transformation parameters will be re-estimated using valid sensor position data only. A weighted least-square minimization is used by considering the sensor lift situation. If a sensor is lifted, the weight for the error related to the sensor will be set to a small weight or zero. Also considered are the geometric properties of sensor locations in weighting the sensor error. A confidence measurement of the sensor data and associated error is performed. The confidence measurement is derived from an error ellipse at 95% confidence level.

    摘要: This invention relates to a composition comprising nano-structured metal oxide particles (particularly, zirconia) and at least one stabilizing agent, a method to produce the composition, and a method to produce the thermally stable nano-structured particles. The method to produce the nano-structured particles comprises first preparing a base solution and a nanoparticle precursor solution, then combining these solutions at a final pH 7 or greater to precipitate a colloidal hydrous oxide. The colloidal hydrous oxide is then treated with at least one silicate, phosphate, or aluminum phosphate stabilizing agent and dried. These nano-structured particle products have high thermal stability and are particularly advantageous in applications as catalysts or catalyst supports that operate at high temperatures.
