Porous materials display interesting transport phenomena due to restricted motion of fluids within the nano- to microscale voids. Here, we investigate how liquid wetting in highly ordered inverse opals is affected by anisotropy in pore geometry. We compare samples with different degrees of pore asphericity and find different wetting patterns depending on the pore shape. Highly anisotropic struc...

Abstract The introduction of different additives into the cooling and lubrication systems in metal cutting process, contributed to improving machining process sustainability. Different types can help reduce friction, wear contact surfaces, improve heat dissipation from zone, etc. With development nanotechnology, great focus has been placed on investigation using nano-particles, nano-additives n...

One method suitable for the accurate characterisation of magnetic fluids is by the measurement of the frequency-dependent, complex susceptibility, χ(ω) = χ′(ω) − iχ′′(ω). Such measurements enable data on, relaxation mechanisms, ferromagnetic resonance, stochastic resonance, non-linear properties, magnetic losses and the signal-to-noise ratio (SNR) of these colloidal nano-particle systems to be ...

The principal objective of the present work is to conduct investigations leading to a more complete explanation of natural convective heat transfer in a partitioned cavity utilizing nano fluids. The nano fluid used, which is composed of Aluminum oxide nano particles in suspension of Ethylene glycol, has been provided at various particle concentrations ranging from 0 to 30% in volume. The study ...

Nanoparticles (NPs) which enter physiological fluids are rapidly coated by proteins, forming a so-called corona which may strongly modify their interaction with tissues and cells relative to the bare NPs. In this work the interactions between a living cell and a nano-object, and in particular the effect on this of the adsorption of serum proteins, are directly examined by measuring the forces a...

In this paper, we model and compute flow-induced mechanical properties of nematic polymer nanocomposites, consisting of transversely isotropic rigid spheroids in an isotropic matrix. Our goal is to fill a gap in the theoretical literature between random and perfectly aligned spheroidal composites (Odegard et al. in Compos. Sci. Technol. 63, 1671–1687, 2003; Gusev et al. in Adv. Eng. Mater. 4(12...

Domestic RO systems are commonly installed in households for water purification and treatment, typically drinking purposes. While effectively remove impurities, such as dissolved salts, minerals, contaminants from tap water, they produce a concentrated waste stream known reject. This reject contains the that were removed during filtration process. can be utilized other domestic, agricultural, i...

We review recent advances in the design, synthesis, and modeling of active fluids. Active fluids have been at center many technological innovations theoretical over past two decades. Research on this new class has inspired by fascinating remarkably efficient strategies that biological systems employ, leading to development biomimetic nano- micro-machines swimmers. The encompasses both micro-sca...

Over the last 15 years molecular dynamics (MD) simulations have become one of the important tools to tackle many of the complex problems that are faced by rheologists and engineers. The advent of modern areas of science such as nanotechnology and the need to understand physical phenomena including rheology and tribology at the molecular scale have helped the growth of research both experimental...

This paper deals with the double-diffusive boundary layer flow of non-Newtonian nano-fluid over a stretching sheet. In this model, where binary nano-fluid is used, the Brownian motion and thermophoresis are classified as the main mechanisms which are responsible for the enhancement ofthe convection features of the nanofluid. By means of the successive approximation method the governing equation...
