Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, Crystal growth rate of lysozyme has been measured in space for the fist time collaborating with an European topical team in 2007. The result was beyond our expectation. Though the growth rate is space has been assumed to be late, the measured growth rate was equal or more than the rate under gravity by 40%. The international team has been trying to understand this result based on both theoretical and experimental studies. Our recent results using in-situ observation system during parabolic flight also showed the increase of growth rate in space. We qualitatively understand that this is due the reduced transport of dimer impurity molecules to the crystal surface under microgravity. However the quantitative analysis cannot explain such a larger increase of growth rate because the reduction of dimer impurity molecules on the surface under microgravity is quite small. This international collaboration has been strengthened by inviting Belgium team to our team. So, Japan, Spanish and Belgium teams will collaborate for the analysis of NanoStep experiment in 2012 and hope to continue the experiment as a post NanoStep project., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065129086},
