With a portfolio of two patents, Orii's innovative work focuses on the development of advanced silica gel particles and precise measurement techniques in gas adsorption and desorption.

Latest Patents

Ryuji Orii's latest patents showcase his groundbreaking work in creating functional materials. His first patent, titled "Method for preparing spherular silica gel particles," outlines a novel technique for producing minute spherular silica gel particles that serve as effective polymer catalyst carriers. This method enables the production of these particles by simply controlling the moisture content in a slurry of silica hydrogel particles and water, without the need for organic substances. The resulting particles possess advantageous physical properties, including an easily controllable specific surface area, average pore diameter, and pore volume, along with sufficient particle strength.

The second patent, "Apparatus and method for measuring adsorption/desorption," presents an innovative approach to determine gas flow rates and adsorption characteristics of solid samples. This method precisely measures the actual flow rate of gas in relation to pressure variances in the reservoir, allowing for accurate calculation of gas not adsorbed in the sample container. By plotting pressure against corresponding adsorption or desorption points, researchers can construct detailed isotherms that reveal essential characteristics such as surface area and pore size distribution.
