Outline of Final Research Achievements |
Abstract I synthesized silica gel-amino acids (L-alanine, L-serine) complexes as basic life materials of original earth life by the sol-gel method. L-alanine and L-serine are included in original earth lives such as diatoms. I revealed also that amino acids are well mixed in this hybrid phase and exist as crystalline and solution phases. The synthetic hybrid materials could be considered as a good model material for comet nuclei. The shock compression experiments for these complexes have been performed and a possibility that amino acids in the comet could reach on the Earth without decomposition. These results may suggest that the impact of comet with life material derived original rife materials.
