Profile

My research fields are spectroscopic analysis (particularly X-ray spectrometry and Secondary ion mass spectrometry) , hydrogen analysis, physical chemistry and Electron microscopy. I aim for development of a novel analytical method and a new scientific discovery using the novel method.
Since March in 2018, I have worked for a radition light beam line: BL05 of NewSUBARU synchrotron radiation facility,University of Hyogo (in the site of SPring-8) as a member of Synchrotron Analysis LLC. I have been engaged in commissioned analysis, instruction for users of BL05, and research on analytical methododlogy regarding chemical state analysis with X-ray-absorption fine structure spectroscopy (XAFS) using synchrotron radiation light.

The following (1) ~ (4) are remarkable research achievements.

(1) The Highly Sensitive Detection Method of Net Hydrogen Charged into Austenitic Stainless Steel with Secondary Ion Mass Spectrometry [1]
How should we analyze local concentration distribution of hydrogen in samlples cut out from metallic hydrogen facilities such as pipe lines or storage tanks? This problem must be dissolved to realize safe and secure hydrogen energy society. This is the sole analytical method that enables accurate local analysis (several micrometers in diameter) of hydrogen contained in metallic material.
In 2017, we for the first time suceeded in detecting and three-dimensionally visualizing "REAL" hydrogen trapped at intermetallic particles in aluminum alloy:6061-T6 exposed to high-pressure hydrogen gas with our original SIMS methodology [5].
