The Tetsuya Suzuki Laboratory develops high-performance thin-film materials and analyzes materials at the atomic level. The lab has developed a technology for industrial applications that creates thin films by breaking down methane and other gases. In particular, diamond films, the hardest known material, are used in various fields and hold great promise for the future. Coating industrial products with a diamond thin film dramatically improves their durability. Leveraging diamond's blood-repellent properties, it is applied in stent surgery. Other applications include turning the bones of deceased pets into diamonds as mementos. Professor Tetsuya Suzuki discusses the potential of diamond thin films across a wide range of fields.
