The aim of the study was to determine the changes in suspension particle size identified in biologically treated wastewater, which was then treated in hydroponic system with use of engineering lighting by the light-emitting diodes (LED). The study was subjected to wastewater purified under laboratory conditions, in a hydroponic system using the effect of macrophytes Pistia stratiotes and growin...

Despite advances in the study of particle selection in suspension-feeding bivalves, the mechanisms upon which bivalves rely to discriminate among particles have not been elucidated. We hypothesized that particle sorting in suspension-feeding bivalves could be based, in part, on a biochemical recognition mechanism mediated by lectins within the mucus that covers the feeding organs. Using Crassos...

Evaporation of suspension droplets on superhydrophobic substrates reveals a dominant shape dependency the resulting supraparticles initial particle concentration.

a nanofluid is a dilute liquid suspension of particles with at least one critical dimension smaller than ~100 nm. research works so far suggest that nanofluids offer excellent heat transfer enhancement over conventional base fluids. the enhancement depends on several factors such as particle shape, particle size distribution, volume fraction of nanoparticles, temperature, ph, and thermal conduc...

Ultrasonic and dielectrophoretic particle manipulation have been studied for particle trajectory modification and particle trapping in microfluidic channels. We report an approach that combines dielectrophoresis (DEP) and ultrasonic fields to trap and concentrate particles and cells in an aqueous suspension. By simultaneously applying electric and ultrasonic fields to the sample, the favorable ...

The problem of compressible boundary-layer laminar flow of a particulate suspension over a semi-infinite fiat plate is solved numerically using the finite-difference methodology. The mathematical model employed includes such effects as particle-phase viscous stresses, variable position-dependent particle slip coefficient, and general power-law viscositytemperature and thermal conductivity-tempe...

It has been hypothesized that, when engulfing food mixed with inorganic particles during benthic feeding, cyprinid fish use protrusions of tissue from the palatal organ to retain the food particles while the inorganic particles are expelled from the opercular slits. In crossflow filtration, the particle suspension is pumped parallel to the filter surface as filtrate exits through the filter por...

The processing of ceramic scaffolds using the ice-templating, or freeze casting, technique provides a relatively simple means to mimic the hierarchical design of natural materials such as nacre. In the present study, we investigated the architecture of silicon carbide (SiC) scaffolds produced by this technique over a range of cooling rates and suspension characteristics to demonstrate its versa...

Electrorheological properties of suspensions are considerably affected by hydrophilicity of suspension particles. As a model material, polyaniline base powder protonated with sulfamic, tartaric, or perfluorooctanesulfonic acids provided particles of various hydrophilicity. The experiments revealed that, in the absence of electric field, due to a good compatibility of hydrophobic polyaniline par...
