摘要: A method of preparing stable, transparent photocatalytic titanium dioxide sots is disclosed which involves thermal treatment of a suspension of amorphous titanium dioxide in the presence of certain alpha-hydroxy acids. The sots comprise titanium dioxide particles in the anatase form having a crystallite size less than about 10 nm and exhibit excellent stability and transparency at basic, neutral, and acid pH.

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.
