The UK-China International Particle Technology Forum IV continues the primary objectives of the previous forums, which was successfully held in Leeds, UK (2007), Guiyang, China (2009), Birmingham, UK (2011) to provide opportunities for scientists and engineers to discuss recent advances, to share knowledge and to identify future research directions in the field of particle science & technology and their roles in environment, energy, healthcare and other emerging applications. It also aims to facilitate communications between scientists and engineers from both academia and industry to establish and strengthen cooperation and collaboration. This forum will be divided into two stages: registration and first two days in Shanghai, and then to Xiuning, (near the famous Huangshan Mountain), Anhui province.
