Title: Sakae Tsuda: Innovator in Porous Material Production
Introduction
Sakae Tsuda is a notable inventor based in Sapporo, Japan. He has made significant contributions to the field of material science, particularly in the production of porous materials. With a total of 4 patents to his name, Tsuda's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of Tsuda's latest patents is a method for producing porous material using antifreeze protein. This method allows for the control of porosity to 50% or higher through a freezing technique. The pore size can be adjusted between 10 µm to 300 µm, ensuring a uniform pore diameter distribution. The process involves freezing a mixture of water and a raw material, which can include ceramic materials, resins, metals, and their precursors. The ice crystals formed during freezing serve as a source for the pores, and the resulting dry material is heat-treated after the ice is removed. The inclusion of antifreeze protein in the mixture enhances the effectiveness of this method.
Another significant patent involves a novel material designed to promote the freezing of water or hydrous substances. This invention features a carrier that immobilizes polypeptides with side chains that bind to water molecules. Additionally, antifreeze proteins are integrated into the carrier, enhancing its ice nucleation activity.
