We are very happy to announce that IAC (International Aerosol Conference) will be held in Busan, Korea from August 28 to September 2, 2014. We will do our very best to host this event and make sure that every scientist and engineer in the field of aerosol science has a nice and comfortable stay while providing various successfully organized programs, including up-to-date technical sessions on current topics of interest. We hope that aerosol scientists and engineers from all over the world will participate in this conference in 2014 not only to exchange the most up-to-date technical information, but also to enjoy getting to know each other as well as learning about Eastern culture and Korean history.
