Stability is key to sustaining the colloidal properties of nanofluids and by extension the beneficial thermophysical properties they exhibit for practical applications. Nanofluid suspensions are typically prepared through ultrasonic dispersion of nanoparticles, either using low-power ultrasonic baths or high-power ultrasonic probes.

We present a nanofluidic diode that at voltage range -5 to +5 V rectifies ion current with degrees of rectification reaching several hundreds. The diode is based on a single asymmetric nanopore whose surface was patterned so that a sharp boundary between positively and negatively charged regions is created. This boundary defines a zone that is enriched

Ionic rectifying effect is a unique ion transport phenomenon observed in certain types of nanofluidic devices and cannot be implemented in microfluidics. Analogous to a diode in solid-state electronics, these diode-like nanofluidic devices can be used to turn the ionic flow on and off depending on the polarity of the applied electric-field.

Abstract We show that macroscale heat conduction in nanofluids is of a dual-phase-lagging type rather than the Fourier type. This leads to models for effective thermal capacity, conductivity and diffusivity of nanofluids and reveals even more anomalous thermal behavior of nanofluids than those reported in the literature. Due to the coupled conduction

Nanofluidics: Fundamentals and applications
TRANSDUCERS 2009 - 2009 International Solid-State Sensors, Actuators and Microsystems Conference, 2009The paper gives a brief overview of nanofluidic theory, with an emphasis on transport processes in nanochannels. It subsequently reports on recent progress in nanofluidic research in the BIOS/Lab-on-a-Chip group, especially DNA electrophoresis in 20-nm high nanoslits, AC electroosmotic flow in nanochannels, and two-phase flow in nano/microfluidic ...

Chaos in Nanofluidic Convection of CuO Nanofluid
2017This paper deals with the nonlinear stability dynamics of nanofluid convection under magnetic and temperature variation for Copper Oxide (CuO) nanofluid, which is used as coolant in heat transfer applications. The system comprises a cavity in which the fluid layer is subjected to external magnetic field and heat exposure.

The uniform dispersion of nanoparticles in the base fluid is applied to many heat transfer and fluid flow processes to investigate the effect of the suspension on the efficiency of the system. The first and foremost condition for practical applicability of nanofluids is the uniform dispersion of nanofluids. So, the stability should be taken care during
