We have also started to apply the metal stable isotopes, e.g., Ca, Fe, Zn, Cd, and Mo, to the studies of numerous, including: a) the evolution of Cd and Zn in the seawater, sinking particles, and the aerosols from the South China Sea and Western Philippines Sea; b) the uptake of Cd by marine phytoplankton; c) the evolution of Cd, Zn, Mo, and Fe isotopes in the sediments of Lake Baikal; d) tracing the aerosol pollutant using the Cd and Zn isotopes; e) the B and Sr isotopes in corals and fluids in mud volcanoes; f) the magma generation and evolution for young volcanic centers in Japan; and g) Fe and Zn isotopes in plants. Furthermore, we have collaborated with researchers from Taiwan and around the world to study Hf isotopes in a variety of different geological settings, including seawater, archean zircons, and terrestrial basalts, as well as Fe and Mo isotopes in river water and sediment samples throughout Taiwan. We have also collaborated with colleagues from Taiwan and China to study a sediment sequence in Lantian, and Fe and Cd isotopes in soil samples from SE China. We have recently started the project to search and study for Ca-Al-rich-Inclusions (CAIs) with fractionated unknown nuclear (FUN) isotopic effects. Lastly, the PI has taken over the principle responsibility of overseeing the AS NanoSIMS facility, and we are currently working on projects related to the areas of cosmochemistry, cell biology, and marine chemistry. Some of these studies have been finished and published, and we are writing the results gradually for the rest.
