Yoshiyuki Amemiya Group
Applied Physics [Quantum Beam Physics]
In my school days & Since then.
When I was a student, I wished to study the basic of the physics deeply and to contribute to the human society through what I had studied. This is the reason why I chose the applied physics as my major. In particular, during my bachelor thesis study, I became interested in developing the new X-ray instrumentation as a tool to observe the nano-structure and its motion in contracting muscle. Since then, I have been involved in the development of X-ray detectors and X-ray optics, particularly for use with synchrotron X-ray radiation, which is an extremely intense x-ray beam emitted from electrons running with the light velocity.
"Seeing is believing" is a basic concept in the materials science. Development of new instrumentation and methods of synchrotron X-ray radiation surely enables us to observe the details of nano-structure and its dynamics in materials and thereby to get not only the knowledge about the relation between structures and functions of materials but also the clues for exploring new function of materials.
Message to students
If you wish to live a vital life, what is most important is keeping strong, tireless and sustainable motivation for what you do in your life.To that end, I would advise you, whenever you tackle with your work,
1) Keep your " Curiosity to the truth " vivid,
2) Fillip your " Passion to what you do ",
3) Become aware of your " Mission to society and human beings",

Introduction of the study
With the advent of synchrotron radiation (SR), brilliant X-rays became available as a probe to observe the detailed structure and its dynamics of materials. In order to make the best use of the brilliant SR, the development of new methods relating to X-ray scattering, X-ray spectroscopy, and X-ray imaging is highly required as well as the development of new instrumentation such as X-ray detectors and X-ray optics. Amemiya’ lab. is aiming to develop new methods and instrumentations for use with brilliant SR and to explore new application fields to study nano-structure and its dynamics of materials. In particular, we are interested in none-crystalline materials such as soft-materials (polymers, rubbers, liquids), which require brilliant and coherent X-ray beam. The methods which we are mainly using are more or less related to SAXS (Small-Angle X-ray Scattering).
Students will have frequent opportunities to go to SPring-8 in Hyogo prefecture and Photon Factory in Tsukuba to carry out their experiments.
In addition, Amemiya’s lab is making vital collaborations with several industrial companies, which have led to successful productions by the companies.
Message from a senior
I have been researching and developing novel methodologies using high brilliant X-rays from synchrotron light sources. Experiments at synchrotron facilities are hard working, but the research is full of discoveries and really fruitful time. Please join us and do research together.
