Silver nanoparticles are being given considerable attention because of their interesting properties and potential applications. One such exploitable use is as the major constituent of conductive inks and pastes used for printing various electronic components. This paper presents a novel direct-writing process for fabrication of the first deposited silver nanoparticles (AgNPs) (50-200nm) elec...

in the present work, the modified nickel electrode was electrochemically fabricated and tested for the electro-oxidation of paracetamol in alkaline media. the methods of cyclic voltammetry (cv), chronoamperometry (ca), and impedance spectroscopy (eis) were used to determine kinetic parameters such as transfer coefficient (α), the catalytic reaction rate constants (k), and the diffusion coeffici...

A WO dimensional. 16-electrode Electrical Impedance Tomography (EIT) system has been simulated using PSPICE to determine whether EIT can be used as a screening technique for early breast cancer detection. Simulation results show that a tumor of area of 1% of the cross-sectional breast model area produces more than 4% variation in the voltage magnitude at the surface electrodes when compared to ...

This paper reports on the development of a micro-potentiometric sensor based on external microelectrodes introduced into a microchip. We miniaturized reference and ion-selective electrodes (ISEs) and embedded them into a plastic (PDMS) microchip; the miniaturization of ISE was attained by using a monolithic capillary-based membrane. This sensor was applied to the detection of alkali ions (Na+, ...

Using an implanted electrode, we recorded the responses from the ultrasound-sensitive mantis interneuron 501-T3 during flying bat attacks in a large flight room where the mantis served as the target. 501-T3 responds to each vocalization emitted with multi-spike bursts when pulse repetition rates (PRRs) are below 55 pulses x s(-1). As PRR increases and pulse durations fall below 3 ms, 501-T3 cea...

A single walled carbon nanotube (SWCNT)-based three-electrode system was fully integrated on glass substrates using a standard microfabrication process and electrochemically characterized using cyclic voltammetry. O(2) plasma functionalization of the SWCNT film working electrode for achieving high sensitivity was voltammetrically optimized with respect to the plasma power and treatment time. Ch...
