The International Conference on Nanomaterials and Atomaterials Science and Applications (ICNASA) will be held at Swinburne on 4-6 July, 2019. It focuses on the most recent advances in the fields of micro/nano/atomic-materials and optoelectronics, especially the new ideas and concepts in modelling, synthesis, fabrication and testing of new materials, structures, devices and systems, and their applications. It provides a global forum to exchange knowledge on nano and atomic materials, engineering, manufacturing and industrialisation.
