Experimental and Theoretical NANOTECHNOLOGY

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.


Theaim of thestudywasthe production ofceramicSiO2nanowires usingthe sol-gel andelectrospinningmethods from solution of PVP/TEOS/AcOH/EtOH. Theobtained fibrousmats wassubjected to preliminarydrying at roomtemperature and next was subjected thecalcinationprocess in airto obtain pureamorphous silicon dioxide nanowires.Analysis of themorphologyandchemical composition ofthe resultingnanowireswascarried out usingascanningelectronmicroscope (SEM) with energydispersivespectrometer (EDS).In order toanalyze the structureof the obtainedmaterials wereusedhigh-resolution transmissionelectronmicroscope (TEM) and X-raydiffractionanalysis (XRD). The analysis of the opticalpropertiesand theenergybandgap of preparednanowireswasdeterminedbyspectralanalysisof theabsorbancein the function oftheenergyof radiationobtained using aUV-Visspectrophotometer.
