Applicant: ENEOS
Patent Publication Number: 2005-150278
While we’re at this topic, the first to apply TiO2 nanotubes for DSC were I and former Kyoto University Professor Adachi (at around the same time). To ensure priority over this work, I published the “humble” paper listed below. Thankfully, until this day, it has been cited a total of 72 times. (^_^)
