This is the third year of Thai Journal of Nanoscience and Nanotechnology for delivery of information on many issues that involve in nanotechnology community. Starting with this issue, it provides five peer-reviewed interdisciplinary research articles in the field of nanoscience and nanotechnology including attractive articles that were selected from the second International Conference on Science and Technology of Emerging Materials 2018 (STEMa2018). On behalf of editorial board, I do have every expectation that it will become one of the most respected journals in the field of nanoscience and nanotechnology. All published articles in Thai Journal of Nanoscience and Nanotechnology can be viewed online with free access via official journal website at http://www.nano.kmitl.ac.th/tjnn.
