Experimental and Theoretical NANOTECHNOLOGY

About the Journal :

Experimental and Theoretical NANOTECHNOLOGY (ETN) is a multidisciplinary peer-reviewed international journal published four issues a year. It includes specialized research papers, short communications, reviews and selected conference papers in special issues on the characterization, synthesis, processing, structure and properties of different principles and applications of NANOTECHNOLOGY; with focus on advantageous achievements and applications for the specialists in engineering, chemistry, physics and materials science.

ETN covers and publishes all aspects of fundamental and applied researches of experimental and theoretical nanoscale technology dealing with materials synthesis, processing, nanofabrication, nanoprobes, spectroscopy, properties, biological systems, nanostructures, nanoelectronics, nano-optics, nano-mechanics, nanodevices, nanobiotechnology, nanomedicine, nanotoxicology within the scope of the journal. ETN aims to acquire the recent and outstanding researches for the benefit of the human being.
