We introduce a new dielectrophoretic particle microconcentrator that combines interdigitated electrodes with a chaotic mixer to achieve high-throughput (>100 microL/min) particle concentration. The interdigitated electrodes use positive dielectrophoresis to attract particles to the surface, while the chaotic mixer circulates the particles to increase the number brought in proximity with the sur...

Homogeneous and rapid mixing in microfluidic devices is difficult to accomplish, owing to the low Reynolds number associated with most flows in microfluidic channels. Here, an efficient electroosmotic micromixer based on a carefully designed lateral structure is demonstrated. The electroosmotic flow in this mixer with an asymmetrical structure induces enhanced disturbance in the micro channel, ...

Emissions and fuel consumption are essential parameters to indicate the working of a combustion engine. This paper discusses methods achieve lower emissions efficient consumption. One is by making emulsion fuel. The emulsion-making surfactant emulsion, micro-emulsion, ultrasonic real-time non-surfactant (RTES). In research, mixture B30 Biodiesel water without that supplied in after being mixed ...

The formation and behaviour of micelles of sodium dodecylsulfate in water byuse of a static micro mixer were studied. Trisbipyridylruthenium(II) was applied asindicator dye, 9-methylanthracene was used for fluorescence quenching. All experimentswere carried out by a micro fluid arrangement with three syringe pumps, a 2 1 two-stepstatic micro mixer (IPHT Jena) and a on-line micro fluorimetry inc...

We present a low noise SIS mixer developed for the 1.2 THz band of the heterodyne spectrometer of the Herschel Space Observatory. The device of this design will be among the first SIS mixers flown in space at Herschel. The developed SIS mixer has a quasi-optical design, with a double slot planar antenna and an extended spherical lens made of pure Si. The SIS junctions are Nb/AlN/NbTiN with the ...

Fluid mixing is a crucial and challenging process for microfluidic systems, which are widely used in biochemical processes. Because of their fast performance, active micromixers that use stirrer blades are considered for biological applications. In the present study, by using a robust and convenient Incompressible Smoothed Particle Hydrodynamics (ISPH) method, miscible mix...
