Our goal is to describe atoms that represent element distribution of the Solar system that are continuously evolving from the beginning to the future. To understand the Solar system with spatial scale 1013 m, we analyze planetary materials that are from different origin with different processes, and determine element and isotope compositions with spatial resolution down to 10-9 m.

Planetary materials besides terrestrial ones are the rolling stones that are sampled with locality unknown. To fill the important missing information, we developed a protocol that is to determine multiple-elements, multiple-isotopes, and multiple-phases. We referred the approach to be 'comprehensive' and construct an analytical system that let us do so. The system acts as a gigantic machine with numerous instruments glued by analytical methods and disciplined people. The disciplines and samples would be taken over to the next generation to sustain our science.

We work as a team and prefer arguments scientifically.


End of the year message


This year has been very difficult for PML. A big earthqueake (6.6 magnitude) damaged a large amount of our facilities affecting the scientific activies of the group. For this new year we are highly determined to exhibit our recovery and enhance our science.
