宮谷正義教授の研究室では、医療用インプラントの生体適合性を向上させるための表面処理技術を開発しています。特に、ナノ秒パulsesレーザー処理を用いた微細な凹凸と酸化被膜の同時形成により、骨接着を促進する表面特性の創出を目的としています。また、電気化学的自己鋸研磨（ELID）を応用した高品質な酸化被膜形成技術の確立も進めています。

In modern computer system, system logs are important for problem determination in troubleshooting. Especially in the troubleshooting of systems, system administrators need to understand overview of the problems and identify the root causes quickly, and system logs can help the system administrators. However large numbers of unfamiliar system logs when are generated problems occur, and it's difficult to understand and use them. Most of the existing methods for interpreting system logs don't work
In this study, we developed a surface modification technology for implants using commercially pure (cp) Ti. The technology used in this study leads to reduction in the time required for adhesion between bone and surfaces of implants. The existence ofmicroasperities and oxide layers is important to induce calcium phosphate precipitation and bone formation activity of osteoblasts. In addition, we focused on nanosecondpulsed laser treatment as a method to create both microasperities and oxide layer
Conventional biomaterials, such as titanium alloys, require enhanced chemical stability and wear resistance, which are dependent on the quality of the surficial oxide layer. However, it is very difficult to produce a sufficiently homogenous oxide layer by polishing using isolation abrasive alone. In our previous study, we proposed a new electrical grinding method (ELID grinding). The process improves oxide formation on the finished surface, resulting in finished surfaces with very thick and pote
