I am Hiroki Kato. I'm from Gifu.
Gifu pref have a lot of nature and foods. Please Look at the "What is Gifu?"
I have many hobbies. For example, I like taking photo of nature, artificial things(historical or modern building, bridge‥etc). I also like going to far place by the Train, the car, and the bicycle.
Viewing of landscape of far place make me blow off steam!
Further more, I like sounds of train running or melody in the station. It is very comfortable!
I also like Hot springs.
It is heal my mind. I want to go every hot springs in Japan!
What is Gifu?
My home town is Gifu pref.
Gifu pref is filled in nature. There is a lot of beautiful landscapes and delicious foods!

My study(For June 6th)
I am studying fiber processing technology using electron beam.
Electron beams are a type of radiation, and can be functionalized into fibers by irradiating fibers with chemical reactions on fibers. When an electron beam is irradiated on a polymer material such as fiber, radicals are generated on the polymer. By adding monomers there, Radical polymerization occurs in the fibers, and graft chains are formed. Functionality can be imparted to fibers by graft polymerization of functional groups. What I am particularly focused on is dyeing. In the general dyeing method, the chemical structure varies depending on the fiber, so it is necessary to select the dye separately. My research is to dye the non-adaptive dye by applying reactive groups of the dye to the fiber by graft polymerization. For example, polyesters can usually be dyed only with disperse dyes. Furthermore, when dyeing with disperse dye, it is necessary to dye at high temperature (130 ℃.) Furthermore, the color fastness of the polyester dyed with the disperse dye is not good. Therefore, if reactive groups of dyes can be introduced into polyester by electron beam graft polymerization, it is considered that dyeing can be carried out even when other dyes are used. Besides dyeing, I am doing research to impart various functionalities to fibers using electron beam graft polymerization. For example, we are introducing water repellency by introducing a long hydrophobic carbon chain into fibers by using electron beams, and on the contrary, SR processing that makes it easy to remove dirt by introducing a hydrophilic functional group.
