Latest Patents
One of Zhu's latest patents is a process for producing nanocrystalline composites. This invention discloses a method to create dense nanocrystalline composites, such as ceramic bodies and coatings, with a uniform microstructure. The process utilizes sol-gel solutions to minimize the agglomeration of nanocrystalline powders during the production of 'green bodies' or intermediate products. This novel approach not only reduces grain growth and porosity during sintering but also results in final grain sizes typically less than 100 nm, achieving densities approaching 99.5% of theoretical values. Additionally, the sintering temperatures required are lower than those in conventional methods, typically below 1,100°C. This process has wide applications in the manufacture of various products, particularly composite coatings and nanodevices.
Another significant patent by Zhu involves a method of interferometry with modulated optical path-length difference. This invention features an interferometer that generates two coherent beams of monochromatic light, directing them through different optical paths with a path-length difference. The system includes a detector for capturing interference signals and a modulator for periodically varying the path-length difference. This allows for the detection of small vibrations without the need for pre-calibration or a feedback servo system. The interferometer's design enables the measurement of minute changes in path-length difference, making it a valuable tool in various applications.
