This year's SNO conference sessions will be organized around selected "systems", e.g. air-water systems. Sessions will be populated with talks on applications, effects and implications, analytical methods, and lifecycle aspects of nanomaterials within each system. The aims are to identity where nanomaterials and nanotechnology can improve the sustainability of each system and to foster integration of knowledge between applications and implications within each system. We also aim to encourage more papers on the applications of nanomaterials. Papers on lifecycle aspects of nanomaterials within each system or across systems is encouraged. New developments in analytical methods and instrumentation are also encouraged. Topics from prior conferences will be regrouped under an appropriate system.
