Photoelectrochemical ion concentration polarization : a microfluidic ion filtration system using light-driven electrochemical reactions [PDF]

open access: yes, 2019
We report an ion separation or filtration method used in microchannel called photoelectrochemical ion concentration polarization (pICP). As a variant of faradaic ion concentration polarization (fICP), pICP utilizes TiO₂ photoelectrochemistry to form an ...

COMSOL Simulation of Bio-MEMS Rotating Microfluidic Mixer [PDF]

open access: yes, 2016
Microfluidic flows in MEMS devices are generally laminar flows, hence the mixing is difficult. To improve the mixing of microfluidic flows, a passive or active micromixer device is needed.

Flow-Ratio Monitoring in a Microchannel by Liquid-Liquid Interface Interferometry

open access: yesProceedings, 2017
A new method to monitor the relative flow rates of two different liquids in a microchannel is presented. By using a simple out-of-plane interferometer setup, shifts in the position of the interface between the two liquids can be determined.

Numerical and Experimental Study on Mixing Performances of Simple and Vortex Micro T-Mixers

open access: yesMicromachines, 2018
Vortex flow increases the interface area of fluid streams by stretching along with providing continuous stirring action to the fluids in micromixers. In this study, experimental and numerical analyses on a design of micromixer that creates vortex flow ...

Finding the optimal design of a passive microfluidic mixer. [PDF]

open access: yes, 2019
The ability to thoroughly mix two fluids is a fundamental need in microfluidics. While a variety of different microfluidic mixers have been designed by researchers, it remains unknown which (if any) of these mixers are optimal (that is, which designs ...

Active Microfluidic Mixer with Fully-Differential Rotary Blades [PDF]

open access: yes, 2016
Mixing of microfluidic flows is difficult due to the fact that microfluid is generally laminar flow and turbulence is not enough. To improve the mixing of microfluid, passive or active microfluidic mixers are developed.
