Particle sorting methods in microfluidic platforms are gaining momentum for various biomedical applications. Bioparticles are found in different shapes and sizes. However, conventional separation techniques are mainly designed for separation of spherical particles. Thus, there is a need to develop new methods for effective separation of spherical and non-spherical bioparticles for various appli...

This paper attempts the well-known regularized gamma distribution function to represent the separation efficiency of particle segregation in gravity concentrators. The model has four parameters that are evaluated by a least square fit between the model estimate and the measured data. The model takes into account the bivariate effects of particle size and particle density to define the size-dens...

Particle separation is of great interest in many biological and biomedical applications. Flow-based methods have been used to sort particles and cells. However, the main challenge with flow based particle separation systems is the need for a sheath flow for successful operation. Existence of the sheath liquid dilutes the analyte, necessitates precise flow control between sample and sheath flow,...

Innovative separation and beneficiation techniques of various materials encountered in electrical and electronic equipment wastes (WEEE) is a major improvement for its recycling. Mechanical separation-oriented characterisation of WEEE was conducted in an attempt to evaluate the amenability of mechanical separation processes. Properties such as liberation degree of fractions (plastics, metals fe...

This paper will present a characterization of a microfluidic device with embedded angled microelectrode arrays for the continuous flow-through dielectrophoretic separation of particles. The operation of the device is demonstrated using samples of colloidal latex spheres, achieving 100% particle deflection with low operating voltage of 10V. This characterization is essential for dielectrophoreti...

Viscoelastic flow-based particle manipulation techniques enable bio-particle focusing, separation, and enrichment by precisely tuning the rheological parameters, flow conditions, microchannel geometry. In this study, we fabricated a PDMS-based single inlet/outlet to separate bio-particles their size ranging from 1-10 μm. Flow conditions properties are optimized using 2 μm 4 Polystyrene beads re...

Examination of the partitioning of particles between the dorsal and ventral regions of the rumen and the buoyancy properties of the particles themselves gives quantitative support for a major role of mechanical entrapment in the dorsal raft in restricting the availability of particles for outflow from the ret iculo-rumen. The effect is greatest for large particles and diminishes with time after...
