Latest Patents
Ooi Kiang Tan's latest patents include a method for providing photocatalytic activity. This invention discloses a method that utilizes nanoparticulate matter comprising a strontium titanate ferrite of the general formula SrTi1-xFexO3-, where x can range from 0 to 1. The nanoparticulate matter is exposed to electromagnetic radiation with wavelengths between approximately 380 nm and 800 nm.
Another significant patent is a process for producing dense nanocrystalline composites. This process aims to create ceramic bodies, coatings, and multi-layered devices with a uniform microstructure. The invention employs sol-gel solutions to minimize the agglomeration of nanocrystalline powders during the production of 'green bodies' or intermediate products. This innovative use of sol-gel solutions also helps reduce grain growth and porosity during sintering, resulting in final grain sizes typically less than 100 nm and densities approaching 99.5% of theoretical densities. Additionally, the required sintering temperatures are lower than those in conventional methods, typically below 1,100°C.
