Polycrystalline ceramics of bismuth layered structure of (Bi2O3)(BaxFe1-xO3) (0.2x0.8, x is in step of 0.2) have been prepared by conventional solid-state reaction method to study its modified dielectric and electrical properties. X-ray diffraction technique is used on the powdered samples for physical characterization and an average grain size of 16 – 21 nm was obtained. The XRD analysis rev...

In this work, a facile method to prepare Bi2O3 decorated activated carbon (Bi2O3@AC) composites with high pseudocapacitive properties was presented. The inorganic–organic synthesized using commercial and active different weight ratio. were assessed spectroscopic, microscopic, diffractive techniques. Our assessments confirmed that carbons successfully doped nanoparticles dopant rates. electroche...

Solid polymer blend electrolyte systems have been prepared with Poly (ethylene oxide) (PEO), (Vinylidene fluoride) (PVdF) and complexed NaNO3 salt by using solution cast method. The complexation of has verified X-Ray diffractogram, Fourier Transform Infrared Spectroscopy Scanning Electron Microscopic studies. AC DC conductivity measurements on these blends were carried out changing the weight p...

A novel impedance spectroscopy technique has been developed for high speed single biological particle analysis. A microfluidic cytometer is used to measure the impedance of single micrometre sized latex particles at high speed across a range of frequencies. The setup uses a technique based on maximum length sequence (MLS) analysis, where the time-dependent response of the system is measured in ...

Electrochemical impedance spectroscopy (EIS) enables the examination of electrochemical nature electrodes and cells by applying an alternating voltage (or current) measuring resulting current voltage). The resistance capacitance components electrode can be evaluated AC changing frequency. In particular, analysis using equivalent circuit determine important parameters related to reaction electro...

Other than concentrating the target molecules at the sensor location, we demonstrate two distinct new advantages of an open-flow impedance-sensing platform for DNA hybridization on carbon nanotube (CNT) surface in the presence of a high-frequency AC electric field. The shear-enhanced DNA and ion transport rate to the CNT surface decouples the parasitic double-layer AC impedance signal from the ...

introduction bladder cancer is the most common malignancy in elderly people and most bladder cancers are transitional cell carcinomas (tcc). bladder pathology is usually investigated visually by cystoscopy and this technique can represent different conditions ranging from simple inflammation to flat cis. however, biopsies must be taken from the suspected area to obtain diagnostic information. t...

the effect of mentha spicata l. extract on the corrosion behaviour of carbon steel in 1.0 m hcl solution was investigated using polarization, electrochemical impedance spectroscopy (eis) and electrochemical noise (en) techniques. the solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (ie). the effect of temperature on the rate of corrosion ...
