High Speed Acoustophoresis for Multiphase Micron-Sized Particle Assembly
Acoustophoresis assembly is a non-contact assembly method characterized by its ability to assemble micron particles in 2D and 3D mm-scale patterns and its material agonism. In this method, acoustic standing wave pressure gradients interact with the particles to generate the acoustic radiation …

Study of Fluid Forces and Heat Transfer on Non-spherical Particles in Assembly Using Particle Resolved Simulation
… Most of the studies have focused on spherical particle shapes, however, in most natural and industrial processes, the particle shape is seldom spherical. In fact, particle shape is one of the important parameters that can have a significant impact on momentum, heat and mass transfer, which are …

A study of brittle powder compaction using a combined discrete finite element approach
… to investigate the behaviour of assemblies of particles in which each particle need not behave in an entirely elastic mamrer. More importantly, discrete crack constitutive models may now be applied to each discrete element. The purpose of this thesis is to simulate the macroscopic behaviour of …

Glia Are Required For Sensory Neuron Morphology And Function In Caenorhabditis elegans
… and may function at an early stage of IFT-B particle assembly. Our results suggest that glia are required for multiple aspects of sensory organ function. Moreover, as thrombospondin 1 is a glial-secreted protein required for synapse formation in mice, these results suggest that some of the …

Dielectrophoretic formation of nanowires and devices
We report the self assembly of nanostructures via. the bottom-up approach by dielectrophoresis. Dielectrophoresis deals with the force on an electric dipole placed in an external in-homogenous field. The force depends on the geometry and volume of the dielectric material and on the frequency and …
