About the Journal :

Experimental and Theoretical NANOTECHNOLOGY (ETN) abbreviated as Exp. Theo. NANOTECHNOLOGY is a multidisciplinary peer-reviewed and open access journal. 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, materials science and medicine. 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.


In this paper, we report an alternate technique for the deposition of nanostructured TiO2 thin films using theelectrohydrodynamicatomization(EHDA)techniqueus- ingpolyvinylpyrrolidone(PVP)asastabilizer.Therequired parameters for achieving uniform TiO2 films using EHDA are also discussed in detail. X-ray diffraction results con- firm that the TiO2 films were oriented in the anatase phase. Scanning electron microscope studies revealed the uniform deposition of the TiO2. The purity of the films is charac- terized by using Fourier transform infrared (FTIR) spec- troscopyandX-rayphotoelectronspectroscopy(XPS),con- firming the presence of Ti–O bonding in the films without anyorganicresidue.TheopticalpropertiesoftheTiO2films were measured by UV-visible spectroscopy, which shows that the transparency of the films is nearly 85% in the visi- bleregion.Thecurrent–voltage(IV)curveoftheTiO2thin filmsshowsanearlylinearbehaviorwith45mQcmofelec- trical resistivity.
