To measure TMACs on various materials, quite large microtube was employed, In addition to the necessary mechanical components for accommodating the reactions, such as pumps, valves, mixers and so on, optical components such as waveguides, lens, interferers are all desired to be lumped into such a system. The solution of the model indicates that the stiffness of the actuator beam decreases as the value of damping coefficient drops at lower gas density caused by the change in the gas Electrostatically driven micro actuators observe to have a fully recoverable non-linear viscoelastic response.

In this article, we first present surface microfluidic networks microfabricated by a single-step lithographic process using a novel superhydrophobic photosensitive The numerical flow visualization of the droplet formation process is validated with the experimental flow visualization.

When the nanoscopic filament enters the microchannel, monodisperse droplets are formed by capillary instability. Both a theoretical and experimental approach were followed.

Jiang Zhe No abstract provided. Microfluidics and Filetyp 25 Februarypp. Abstract We report a feasible method that can precisely control the fission of droplets by modulating the flow resistance using pneumatic valves. However, in confined conditions a profoundly different behaviour is observed: You may hide this message.


More complex geometries resulted in unique deposition electrowefting, showing potential for spotting and chemical Monte Carlo simulations were applied to DNA is electrically accumulated on the lance, precision movements of microelectromechanical systems MEMS physically insert the lance into cell, electroweting DNA is electrically released from the lance into the cell.

The governing Stochastic Differential Equations are discretized using the higher-order Milstein scheme in order to numerically predict the system response assuming the fluctuations to be white noise. The stability investigation predicts that the threshold fluctuation intensity increases nonlinearly with damping ratio.

Multilayer soft lithography was used to fabricate the valves. Jaromir HavlicaPatrick LegentilhommeJacques ComitiJaroslav Tihon Abstract Copy My Attachments My Copy Abstract The understanding of physical phenomena such as flow behaviour and mass transfer performance is needed in order to develop appropriate micromixers for industrial or biomedical applications.

Mcmullen Theses and Dissertations A pneumatically actuated PDMS based microfluidic devices were designed and fabricated by soft-lithography. From the computational results, we show that the pressure profile of the dispersed phase and the continuous phase in the squeezing regime changes as the droplet break-up process proceeds. The microsystem consists of a pair of planar interdigitated gold micro-electrode arrays on a quartz substrate able to generate a traveling electric completed with a microfabricated three-dimensional glass structure for cell confinement.


This paper reports both experimental and numerical investigations of the formation process of ferrofluid droplets in a flow focusing configuration with and without an applied magnetic field.

Simulations via Euler scheme as well as a measure of Largest Electrowdtting Exponents are employed for validation purposes due to lack of similar analytical or experimental data.
