On behalf of the organizing committee, I would like to invite you to participate in the International Conference on Nanoscience and Technology, China 2013 (ChinaNANO 2013) which will be held between September 5-7, 2013 in Beijing, China. This is the fifth conference following the successful ChinaNANO 2005, ChinaNANO 2007, ChinaNANO 2009 and ChinaNANO 2011 held in Beijing, respectively. ChinaNANO 2013 is intended to stimulate discussions on the forefront of research in nanoscience and nanotechnology. The conference will focus on inorganic nanomaterials and MOFs, carbon nanomaterials, soft nanomaterials, nanocomposites and applications, energy and environmental nanotechnology, nanophotonics and optoelectronics, nanodevices and nanosystems, nanobiotechnology and nanomedicine, nanocharacterization and metrology, as well as modeling and simulation of nanostructures. We sincerely hope that the scope of the conference will serve the interest of the scientific community, as well as the industry and the general public. I wish to extend my welcome to all participants and sponsors of the event.
