Microfluidics and Nanofluidics 22 Novemberpp. In this study, we use the DPD approach to model the motion of circular and elliptical particles in a 2D shear laminar flow. This periodic arrangement creates phononic bandgaps, and modifies phononic bandstructures of a material. Luo Abstract Copy My Attachments My Copy Abstract Microfluidic devices with micro-sieve plate as the dispersion medium have been widely used for the mass production of emulsions.

However, this technology requires precise control of the surface profile of microlenses, which is a major technical challenge.

Fracture toughness of the Ni Microfluidics and Nanofluidics 15 Decemberpp. Abstract Ethanol consumption is associated with the risk of breast cancer progression; however, the mechanism of relationship has not yet been fully explained. Two calibration curves for determining the concentrations of urinary albumin A wide range of MEMS devices are used in every aspects of our life, from microaccelerators and microgyroscopes to microscale drug-delivery systems.

A PDMS molding and bonding process is used to fabricate the proposed microfluidic devices. Although several applications of electrowetting on dielectric digital lab-on-a-chips are reported in literature, there is still a lack of knowledge about the influence of operational and design parameters on the performance of an analytical assay.

In this dissertation, the surface forming process of the out-of-plane microlenses in UV-lithography fabrication was modeled and simulated using a simplified cellular automata model. Microfluidics and Nanofluidics 30 Novemberpp. Abstract Droplet breakup in systems with either a viscoelastic matrix or a viscoelastic droplet is studied microscopically in bulk and confined shear flow, using a parallel plate counter rotating shear flow cell.


A torsional testing procedure provided an Microfluidics and Nanofluidics 18 Februarypp. The bonding was carried out under a pressure of 1.

Electrowetting of a 3D drop: numerical modelling with electrostatic vector fields

A possible explanation for the enhanced flow in carbon nanotubes is given using a mathematical model that includes a depletion layer with reduced viscosity near the wall. The corrosion rate can be monitored by detecting the resistivity change in sensing elements.

Emulsion droplets functioning as templates and reactors are employed to realize the synthesis process. Md Abdul Haseeb Nanocrystalline nickel-tungsten alloys have great potential in the fabrication of components for microelectromechanical systems. Recently, the second author obtained convincing results in the 2D axisymmetric case. Only the controls for the widget will be shown in your chosen language.

The high density integration of the eo pump required a small footprint as well as a specific on-chip design to ventilate the electrolyzed gases emerging at the platinum Pt electrodes. Abstract We report a feasible method that can precisely control the fission of elecrrowetting by modulating the flow resistance using pneumatic valves.

The solution of the model indicates that the stiffness of the actuator electrowegting decreases as the value of damping coefficient drops at lower gas density caused by the change in the gas Ethanol consumption is associated with the risk of breast cancer progression; however, the mechanism of relationship has not yet been fully explained. This paper investigates how droplet size variability, introduced by droplet dispensing and splitting, influences the assay performance with respect to repeatability and accuracy and presents a novel method to reduce this variability.
