In this paper, the cyclic voltammetry behavior of Ferrocyanide/Ferricyanide, which is commonly used for electrochemical DNA detection experiment, was studied in the commercial EQCM-D setup (Q-sense) using the COMSOL Multiphysics. The model was established in a 3D geometry of QCM liquid cell. The simulation shows depletion of concentration of ferrocyanice following applied electrode potential. ...

Electrodeposition has a major advantage over other methods of thin film deposition. It allows deposition at atmospheric pressure and room temperature, requiring inexpensive equipment. However, there are several parameters which can influence an electroplated metal layer quality. The current density distribution is taken into consideration. The Hull cell is an electrodeposition tank with a ...

The proposed State of Charge (SOC) governed fast charging method for secondary lithium based batteries charges a battery many times faster than the normal Constant Current-Constant Voltage (CC-CV) charging and reduces the side-effects generally accompanied by various fast charging methods. The proposed charging algorithm takes into account the varying internal impedance of the battery at ...

Low cost high energy density batteries that can be charged and discharged rapidly are required in a number of applications. Tapping energy from renewal resources such as solar, wind and tide requires rapidly generated energy to be first stored and then used round the clock. Storing energy of a moving vehicle as it slows down and recovering it to accelerate the vehicle later can significantly ...

Additive manufacturing uses 3D printing to build physical parts from CAD-based designs. The technology includes fused deposition modeling (FDM) and selective laser sintering (SLS) methods. 3-D printing is of particular interest for smaller, one-of-a-kind, customizable products. A cube satellite (CubeSat) containing fiber reinforced SLS parts has been successfully launched (Ref 1). Lower ...

Galvanic corrosion is encountered in marine applications because one often has dissimilar metal joints and seawater acts as an electrolyte. One metal acts predominantly as anode and undergoes material dissolution while the other acts predominantly as cathode and is the site where a cathodic reaction takes place. Assuming a stagnant electrolyte, the equation governing the distribution of ...

The corrosion at cut-made edges is significant due to the anode to cathode surface ratio in this region. The major problems are the risks of red rust appearance at the exposed steel surface, and the risks of paint delamination in case of insufficient corrosion protection. The work presented here focuses on the development of a 2D FEM model simulating a steady state corrosion situation at a cut ...

Ionic wind is the gas flow induced by the corona discharge. Ions produced by corona are accelerated by electric field and transfer their momentum to neutral molecules. Using ionic wind one can convert electric energy to kinetic energy of air flow almost directly. The phenomenon of ionic wind finds applications in electrostatic precipitators and ionizers. It is difficult to solve the complete ...

This paper discusses the simulation studies on a vibration based energy harvesting system to convert the undesirable mechanical vibration to useful green power. The design consists of a resonating proof mass and a spring system enclosed in housing and fixed on the source of vibration. A piezoelectric suspension acts as the transducer and generates a voltage that is used to charge the batteries of ...
