The process of removing indium ions from aqueous solutions by applying capacitive deionization (CDI) is reported in this manuscript. First, a modified carbon material was prepared incorporating titanium dioxide (TiO2) into activated (AC). A microwave-assisted ionothermal synthesis (MAIS) method used to produce evenly distributed nanostructured anatase TiO2 on the surface AC. polyurethane (PU) e...

A new transmission line structure is presented in this work for advanced CMOS processes. This structure has a high quality factor and low attenuation. It allows slow-waves to propagate which results in low dispersion for a given characteristic impedance. It is also designed to satisfy the stringent density requirements of advanced CMOS processes. A model is developed to characterize this struct...

Polymer blend electrolytes have been prepared using the casting technique. The electrolyte is composed of two polymers polyvinyl alcohol (PVA)/polyvinylpyrrolidone (PVP)) with a fixed ratio (50 : 50) loaded varied ratios FeCl2 (0.5, 1, and 2 wt.%). impedance analysis indicates that AC conductivity increased as temperature was following power law. Nyquist plots for pure composite samples present...

The universality of the ac electrical transport in granular metals has been scarcely studied and the actual mechanisms involved in the scaling laws are not well understood. Previous works have reported on the scaling of capacitance and dielectric loss at different temperatures in Co-ZrO2 granular metals. However, the characteristic frequency used to scale the conductivity spectra has not been d...

The temperature dependent dielectric spectroscopic properties of two heteronuclear complexes of monoethanolamine (MEA) at a wide temperature range (303-413 K) were investigated by impedance spectroscopy, in the frequency range from 100 Hz to 100 kHz. The frequency dependence of the impedance spectra plotted in the complex plane shows semi-circles. The Cole-Cole diagrams have been used to determ...

Herein we report the Fe3O4-oleate (Fe-OA) nanoparticles (NPs) incorporated poly (vinyl alcohol) (PVA), a series of highly flexible nanocomposites (Fe-OA-PVA) were prepared by solution casting technique. The fabricated with different weights per cent (0.25 wt. %, 0.5wt. and 0.75wt. 1wt. 2wt. respectively) Fe3O4-OA into PVA matrix. synthesized characterized using FTIR, UV–Vis, XRD, Contact angle,...
