Special issue on nanofluids [PDF]

open access: yesNanoscale Research Letters, 2011
Nanofluids, or fluid suspensions of nanometer-sized structures, are research challenges of rare potential but daunting difficulty. The potential comes from both scientific and practical opportunities in many fields. The difficulty reflects the issues related to multiscales.

Molecular dynamic simulation on the density of titanium dioxide and silver water-based nanofluids [PDF]

open access: yesJournal of Molecular Liquids 333 (2021) 115966, 2021
This study utilizes molecular dynamics simulations to scrutinize the influence of type and volume fraction of nanoparticle on the density of nanofluids, i.e. silver (as a hydrophilic case) and titanium dioxide (as a hydrophobic case) water-based nanofluids.

Statistical Analysis of Thermal Conductivity Experimentally Measured in Water-Based Nanofluids [PDF]

open access: yesProc. R. Soc. A, 477:20210222, 2021, 2021
Nanofluids are suspensions of nanoparticles in a base heat-transfer liquid. They have been widely investigated to boost heat transfer since they were proposed in the 1990's. We present a statistical correlation analysis of experimentally measured thermal conductivity of water-based nanofluids available in the literature.

Dispersion stability and thermal conductivity of propylene glycol-based nanofluids [PDF]

open access: yesJ. Nanopart Res (2011) 13:5049-5055, 2012
The dispersion stability and thermal conductivity of propylene glycol based nanofluids containing Al2O3 and TiO2 nanoparticles were studied in the temperature range of 20 to 80 {\deg}C. Nanofluids with different concentrations of nanoparticles were formulated by the two-step method without use of dispersants.

Nanofluidic Devices and Their Applications [PDF]

open access: yesAnalytical Chemistry, 2008
Recent developments in micro- and nanotechnologies made possible the fabrication of devices integrating a deterministic network of nanochannels, i.e., with at least one dimension in a range from 1 to 100 nm. The proximity of this dimension and the Debye length, the size of biomolecules such as DNA or proteins, or even the slip length, added to the ...

Increasing the accuracy of estimating the dynamic viscosity of hybrid nano-lubricants containing MWCNT-MgO by optimizing using an artificial neural network

open access: yesArabian Journal of Chemistry, 2023
Artificial neural network (ANN) is utilized as efficient models to forecast the nanofluids (NFs) viscosity (μnf). In this examination, ANN is used to forecast the μnf of the MWCNT-MgO (25 % −75 %) / SAE40 nano-lubricant (NL) experimental data set ...
