Outline of Final Research Achievements

Unusual structures and properties of materials at two extreme environments, outer space mimicked by inner column of an electron microscope and confined nano spaces in inner of carbon nanotubes, were studied by transmission electron microscopy and electron energy loss spectroscopy. Experimental results suggest that amino acids may be able to be protected from high energy ray irradiation by ionic liquid coating. The results imply that amino acids can survive at outer space when the amino acids are protected by these materials. Also we found that van der Waals interaction between host materials which form the confined nano space and guest materials significantly affects structure and properties of the guest materials in the confined nanospace. The results provide important theoretical suggestions for development of nano devices by applying the confined nano space.
