The electrification of the powertrain requires enhanced performance lithium-ion batteries, mainly in terms energy and power density. They can be improved by optimising positive electrode, i.e., changing their size, composition or morphology. Thick electrodes increase gravimetric density but generally have an inefficient performance. This work presents a 2D modelling approach for better understa...

Abstract To explore the influence of different processing parameters on efficiency electrochemical machining and surface morphology, removal spikes was simulated by COMSOL Multiphysics simulation software. And combined with experiments, micro-surface analyzed compared. The results showed that amount increased increase voltage, time, electrolyte concentration, decreased in gap. appropriate not o...

introduction             wastewater treatment using activated sludge process (asp) produces huge amounts of sludge that must be treated by efficient methods. wastewater sludge handling is one of the most important economic-technical challenges of wastewater treatment projects. conventional methods for this purpose are very time consuming, expensive and in lots of cases have limited success. in ...

This document provides an inventory of the parameters that are in use to describe impedances of electrochemical cells. The definitions of these parameters are given, as well as recommendations for their terminology and nomenclature. Where relevant, experimental determination of a parameter and limitations to its validity are briefly discussed.

The production and assembling of disposable electrochemical AFM1 immunosensors, which can combine the high selectivity of immunoanalysis with the ease of the electrochemical probes, has been carried out. Firstly immunoassay parameters such as amounts of antibody and labelled antigen, buffer and pH, length of time and temperature of each steps (precoating, coating, binding and competition steps)...

Aluminium metal matrix composites (AMMCs) are now gaining their usage in aerospace and automotive industries because of their inherent properties like high strength to weight ratio, low wear rate etc. Electrochemical Machining (ECM) allowed success in the production of newer materials, especially for the aerospace and biomedical applications. In this paper an attempt is made to machine the LM6 ...

An electrochemical cell consisting of two copper electrodes and copper sulphate solutions is modeled. The presented model takes into account both electrode interfaces and the activity of copper(II) ions. The current-potential equation is derived and a method for identifying mass-transfer parameters as well as kinetic parameters is proposed for a specific case. The created model is simulated and...

A multiparametric system able to classify red and white wines according to the grape varieties and for analysing some specific parameters is presented. The system, known as hybrid electronic tongue, consists of an array of electrochemical microsensors and a colorimetric optofluidic system. The array of electrochemical sensors is composed of six ISFETs based sensors, a conductivity sensor, a red...

Scanning Electrochemical Microscopy is a tool for imaging and investigate surfaces by meaning of chemical reactivity, electric conductivity, and enzymatic activity. This technique is typical electrochemical cell plus three axis positioner. Positioner allows to measure typical electrochemical measurements, like Cyclic Voltammetry, Chronoamperometry, Impedance Spectroscopy, etc. in the vicinity o...
