Dielectrophoretic separation of particles finds a variety of applications in the capture of species such as cells, viruses, proteins, DNA from biological systems, as well as other organic and inorganic contaminants from water. The ability to capture particles is constrained by poor volumetric scaling of separation force with respect to particle diameter, as well as the weak penetration of elect...

The Corning Advanced-FlowTM Reactor (AFR) whose productivity is ready for scale-up with limited loss of transport properties was implemented in the continuous synthesis Ag nanoparticles (NPs). To demonstrate effect mixing on NPs, flow pattern and characteristic (mainly meso- macroscale) AFR were studied by visualisation computational fluid dynamics simulation first. It found that increasing tot...

Emulsions formed by mixing reactant streams inside microdroplets are efficient microscale reactors for the synthesis of nano/microparticles/crystals due to small quantities reagents confined within each droplet and separation contents from reactor walls. In this work, size-tunable gold nanoparticles (AuNPs) emulsion droplets generated in a three-phase glass capillary microfluidic device was inv...

Various approaches to structure gas-solid fluidized beds are reviewed, followed by detailed discussion on the use of gas pulsation induce dynamic structuring. Granular media dissipative systems, which develop complex spatiotemporal patterns when excited an oscillating energy source. Here, we discuss how such perturbations initiate surface and these could propagate into a macroscopically organiz...

Microfluidic devices have become a new trend in different fields and attracted attention due to their compact size capability deal with small amount of fluid. Micromixing is an efficient way mix miscible fluids at this microfluidic level. This work explores approach for optimization microfluidics, using CFD (Computational Fluid Dynamics) ML (Machine Learning) techniques. The objective combinati...

Probability density function methods for characterizing various fluctuating quantities in the reacting gas phase of turbulent spray flames are presented, development which O'Brien has been a pioneer. Balance equations two-phase flows considered as piecewise continuous medium first presented with interface conditions containing vaporization–condensation equilibrium. From these, equation joint pr...

Surface acoustic waves (SAWs), which are 10 MHz order surface waves roughly 10 nm in amplitude propagating on the surface of a piezoelectric substrate, can offer a powerful method for driving fast microfluidic actuation and microparticle or biomolecule manipulation. We demonstrate that sessile drops can be linearly translated on planar substrates or fluid can be pumped through microchannels at ...
