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.
The research involves the preparation of the nano-accepters, titanium dioxide (TiO2). It is diagnose by different techniques such as IR, AFM, SEM, XRD and EDX, which illustrated the topographic features and features of the nano-crystalline prepared in terms of crystalline level, size of minute, pore shape, and elements analysis and et al. The study also includes a spectroscopic study of the transfer complexes of the charge using nano-TiO2 as the accepters electron with the alizarin dye extracted as donor electrons using absolute ethanol as a solvent. The Bensi-Hildebrand equation is applied to calculate the equilibrium constant and the molecular absorption coefficient of the resulting complex. The linear relationship resulting from the application of the equation showed that the forward ratio of the talent to the receiver is 1: 1. The effect of temperature change at the range (293-313 °K) was study on the equilibrium constants calculated from the Bensi-Hildebrand equation and used in the calculation of thermodynamic functions ΔH°, ΔS° and ΔG°. Negative values ΔG° showed that the reaction was automatic and the positive values ΔH° Indicate that the interaction of the composition of the complex is endothermic, while the positive values ΔS° are indicative of the random reaction. The stability energy of the complex complexes is calculated and is equal to (2.24 eV) as well as the calculation of the ionization Potential and the dissociation energy of the excitation state of these complexities and other physical properties. The kinetics of the transition of the prepared charge complexes were studied in the absolute ethanol solvent. The results of the study showed that the kinetics of the formation and decomposition of the complexes are first order.
