Outline of Final Research Achievements

I have proposed a designed hyper flow reactor intended for simulating various hydrothermal environments for experimental verification of the chemical evolution process leading to the origin of life in the Hadean Earth. The hyper flow reactor consists of a high temperature chamber and a low temerature chamber, was realized high temperature and high pressure environment of 400 degree and 30 MPa in a non-equilibrium open system. It had been confirmed that it has the ability to simulate various hydrothermal environments from submarine hydrothermal vents to onshore hot springs. It was found that the temperature of hot water and the high temperature residence time are dominant the polymerization reaction of amino acids.
