Latest Patents

Among her latest inventions, Yasuko has developed a sophisticated ozone detecting device. This device features a vessel containing a specialized detector solution, which is an aqueous mixture designed by dissolving a detector component that includes a dye. This dye undergoes a color change upon reaction with ozone gas. The process involves preparing a sheet-like carrier that is dipped into this detector solution for approximately 30 seconds, resulting in an impregnated sheet. Post-impregnation, the sheet is dried, causing the solvent, typically water, to evaporate and forming the final ozone detecting device.

Another notable patent involves a similar approach where an aqueous solution consisting of a dye made from alizarin, along with a humectant like glycerin, is alkalized using a base. This results in a detector solution with about 20 wt% of the humectant. A cellulose filter paper serves as the sheet-like carrier that is similarly dipped into the solution for 30 seconds, pulled up, and then dried in dry nitrogen to effectively create another version of the ozone detecting device.
