Correlating gene expression with behavior at the single-cell level is difficult, largely because the small amount of available mRNA (<1 pg) degrades before it can be reverse transcribed into a more stable cDNA copy. This study tested the capacity for a novel acoustic microstreaming method ("micromixing"), which stirs fluid at microliter scales, to improve cDNA yields from reverse transcription ...

This paper presents the micromixing times in a rotor-stator spinning disc reactor. Segregation indices are obtained at different rotational speeds performing the Villermaux-Dushman parallel-competitive reaction scheme. Consequently, the corresponding micromixing times are calculated using the engulfment model, while considering the self-engulfment effect. It was found that the segregation index...

The miscible liquid-liquid two phases based on Taylor flow in microchannels was investigated by high-speed imaging techniques and Villermaux/Dushman reaction. The mixing based on Taylor flow was much better compared with that without introducing gas in microchannels, even the ideal micromixing performance could be obtained under optimized superficial gas and liquid velocities. In the mixing pro...

Two-Color Laser Induced Fluorescence (LIF) Technique enables the measurement of the progress in mixing on macroand microscale simultaneously. This is done by injecting a mixture of an inert and a reacting fluorescent dye into the vessel. The inert dye serves as a tracer for the macromixing but does not predicate the mixing quality on the nano scale. Since the chemical reaction requires mixing o...

Micromixing in a tubular polymerization reactor is characterized by the molecular mass of polystyrene obtained in the presence of a chain transfer agent. Monomer and the transfer agent are fed separately into the reactor. For constant overall inlet concentrations, the mean molecular mass produced is strongly dependent on mixing intensity. Experiments were carried out in a pilot plant loop tubul...

Micromixing is a crucial process within microfluidic systems such as micro total analysis systems (μTAS). A state-of-art review on microstructured mixing devices and their mixing phenomena is given. The review first presents an overview of the characteristics of fluidic behavior at the microscale and their implications in microfluidic mixing processes. According to the two basic principles expl...

Selective monoiodination of aromatic compounds such as dimethoxybenzene has been successfully achieved with I+, which is generated by anodic oxidation of I2 in acetonitrile, using micromixing.
