In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of the electric field. DEP is caused by polarization of the DNA particle. Two different electrode geometries ...

Continuous flow reactors are recently being used for lab scale synthesis as well as pilot scale manufacturing of high value low volume chemicals. Here we present our work on a new configuration of flow reactor that includes several 1800 bends and yet a varying radius of curvature thereby yielding continuous change in the direction of streamlines. Experiments as well as simulations (in COMSOL ...

The Automotive industry has now become a technology of “Drive by Wire”. This technology is used to replace the conventional mechanical system by electromechanical system which is able to perform the same tasks faster, more reliably and accurately. The problems with the traditional braking systems are unreliable at high speeds, long respond time, more brake pad wear, high temperature ...

A fuel cell is an efficient and clean alternative power source of energy. Alkaline anion exchange membrane (AAEM) fuel cells are one in which conduction of oH- (hydroxyl ion) take place. The advantages of using alkaline fuel cells over proton exchange membrane fuel cells is that electrochemical kinetics is fast and alkaline environment is friendly for catalysts. Experiments performed at ...

One of the major challenges faced by the semiconductor industry is that electronic circuits produce a lot of heat energy during their operation. And with the current scenario where the gates are packed so much close together, then the problem of heat generation has become extremely significant. So we are working towards the efficient heat management and dissipation solution for the heat generated ...

Sodium is used as a coolant in Fast Breeder Reactors. Eddy Current Flowmeter (ECFM) is used for measurement of sodium flow in the primary pump and at the outlet of the subassemblies. Eddy Current Flowmeter (ECFM) works on the principle of change in the magnetic field profile due to induced eddy currents as a result of sodium flow. It consists of a central primary winding, energized from an A.C. ...

Ion implantation in insulating materials leads to local variations in mechanical and optical properties that can be exploited for the fabrication of micro-structures. In particular, ion irradiation of diamond causes the formation of buried amorphised layers, with correspondent mass density and refractive index variations that depend on the level of “damage” of the crystal structure. ...

This paper describes the modeling of an electrochemical biosensor embedded in a microfluidic channel to determine the concentration of a target biomolecule. The total amount of analyte in the sample can be calculated by integrating the analyte concentration over the duration of the peak current. The biosensor is constructed by immobilizing redox-enzyme on an interdigitated array (IDA) electrode ...

Single photon emission computed tomography (SPECT) is a nuclear medicine imaging technique that uses gamma rays. It has been especially useful for bone scans, cardiac perfusion imaging, tumor scans and brain imaging. The main advantage of SPECT imaging is that it can target particular tissue receptors allowing one to focus on the imaging of the diseased tissue. In most cases Monte Carlo ...

Mineral precipitation on to the quartz surface of the lamp jackets in UV disinfection process (fouling) has been recognized as a major problem for UV radiation delivery during disinfection operation. Fouling behavior was observed to be induced thermally and influenced by hydraulic character of the UV disinfection configuration. Fouling process involves momentum, heat, and mass transport within ...
