01About This Special Issue
Nanotechnology is a so-called breaking-technology, which dramatically changes the society. To reflect the recent achievements in the nanoresearch, the Tbilisi (Georgia) scientific conferences on nanotechnologies are held regularly (every two years) since 2010. The coming 4th International Conference “Nanotechnologies”, October 24 – 27, 2016, Tbilisi, Georgia (Nano – 2016) will be devoted the methods of synthesizing of nanomaterials, studying their structure, chemical, physical and technological properties, as well as applications in techniques. Conference will provide an evaluation of the present state-of-art in this field of knowledge, newly obtained results and prospects of developments in nanotechnologies.This Special Issue of the American Journal of Nano Research and Applications is to publish part of Conference Papers presented at the Nano – 2016. Participants / authors, who have sent Abstracts of conference presentations to the Organizing Committee, are invited to submit their valuable presentations in the form of full-text papers in this Special Issue.
