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, ...

Two novel passive micromixers, denoted as the Y-Y mixer and the H-C mixer, based on split-and-recombine (SAR) principle are studied both experimentally and numerically over Reynolds numbers ranging from 1 to 100. An image analysis technique was used to evaluate mixture homogeneity at four target areas. Numerical simulations were found to be a useful support for the design phase, since a general...

Introduction: Neurohormones like testosterone and estradiol have an important role in learning and memory. The hippocampus is essentially involved in learning and memory, and is known to be a target for estradiol actions. Estrogen receptors (ERs) are highly expressed in CA1 of rat hippocampus, and mediate the effects of estrogen on learning and memory. Estradiol receptor belong to a family ...

An integrated microdevice, consisting of a micropump, a passive mixer, a magnetic separation chamber, and a microcapillary electrophoretic channel, was constructed for biobarcode assay based multiplex biological agent detection in a sample-to-answer-out manner within 30 min with high sensitivity.

Passive mixing based on microfluidics has won its popularity for its unique advantage, including easier operation, more efficient mixing performance and higher access to high integrity. The time-scale and performance of mixing process are usually characterized by mixing quality, which has been remarkably improved due to the introduction of chaos theory into passive micro mixers. In this paper, ...

The creation of complex three-dimensional (3D) fluidic systems composed of hollow microand nanostructures embedded in transparent substrates has attracted significant attention from both scientific and applied research communities. However, it is by now still a formidable challenge to build 3D microand nanofluidic structures with arbitrary configurations using conventional planar lithographic f...

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 ...
