Dear Readers,

This is the fourth year of Thai Journal of Nanoscience and Nanotechnology (TJNN) published in 2019 by College of Nanotechnology, King Mongkut’s Institute of Technology Ladkrabang. TJNN reports on fundamental research in all branches that involve nanoscience and nanotechnology community. This issue provides three attractive peer-reviewed interdisciplinary research articles of the preparations, characterizations, and applications of nanomaterials.

On behalf of editorial board, I do have every expectation that TJNN will become one of the most appreciated journals in the field of nanoscience and nanotechnology and will be technically useful for all readers and researchers in this community. TJNN invites original reports of fundamental research in all branches of the theory and practice 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
