Steps, hops and turns: examining the effects of channel shapes on mass transfer in continuous electrochemical reactors

Solution moving through an electrode, hence hopping from one electrode to another, has the greatest effect on an electrochemical reaction when compared to simple turns within a flow channel.

MAKING PROTOTYPE OF ELECTRO PLATING EQUIPMENT FOR HOME INDUSTRYOME INDUSTRI

Corrosion is an electrochemical reaction process that is natural and takes place by itself, corrosion cannot be prevented or stopped but can only be controlled using the Electro Plating method. Electroplating is a process that produces a thin layer of metal on top of another metal surface by electrolysis or electroplating using direct current (DC) and chemical solutions (electrolytes). The process of giving this protective layer aims to protect the metal from corrosion, in this study, will make a prototype electro plating tool for small industry or Home Industry, the completeness of the components needed to make a prototype electro plating tool is an AC transformer matic 30-50 A 12V, ampere meter, volt meter, fuse and switch, then nickel solution serves to provide strength, metal resistance from rust and chrome solution serves to provide resistance to corrosion and gives a glossy white color so it looks better, to produce a strong coating. With the occurrence of the anode, cathode, and electrolyte solution which are used entirely as related to coating materials, especially metals are illustrated as, the cathode can be interpreted as the workpiece to be coated, connected to the negative pole of the electric current source and the electrolyte in the form of a solution whose molecules can be dissolved. in water and decomposes into positively or negatively charged particles and the deposition in the process is due to the presence of ions in the electrolyte and will settle on the cathode and the process of coating the metal occursPlease write your abstract in English version here.

Modelling of Electrode Size Influence on Electrochemical MHD Processes

The presented article describes a simulation of an electrochemical reaction in a presence of a magnetic field using a custom model implemented into Ansys Fluent. The influence of electrode size and the effect of scan rate is investigated further. The results show that the magnetic field can significantly increase mixing and transport of species towards the electrode, which results in higher obtained current densities. Additionally, this method can be used to control fluid flow in microfluidic devices.

Cylindrical model of electrochromic colouration of hydrated vanadium pentoxide thin films with point contacts

This article analyses experiments on the kinetics of the internal electrochromism of thin (micron) films of hydrated vanadium pentoxide xerogel with point contacts. It describes a cylindrical model of electrochromic colouration, which was used to evaluate the concentration of the colour centres in the initial film and after additional hydrogenation of this film by plasmaimmersion ion implantation.When we compared the calculated values of the concentration of colour centres with the equilibrium concentration of protons in the xerogel, we saw that the mobility of the protons migrating from the depth of the film to the cathode region, which are involved in the electrochemical reaction, was not a determinant of the electrochromism kinetics.The rate of electrochromic colouration could be increased by the formation of layered film structures based on hydrated vanadium pentoxide, which have increased overall electron conductivity and, as a consequence, low faradaic resistance of the electrochromic cathodic reaction.
