Droplet Microfluidics for Fabrication of Non‐Spherical Particles
Macromolecular Rapid Communications, 2010AbstractWe describe new developments for controlled fabrication of monodisperse non‐spherical particles using droplet microfluidics. The high degree of control afforded by microfluidic technologies enables generation of single and multiple emulsion droplets.

Dielectrophoresis of non-spherical particles
Journal of Physics D: Applied Physics, 2009Dielectrophoresis of non-spherical particles is attracting attention, particularly for the aligned deposition of nanowires and nanotubes. The orientation and translation of ellipsoids are studied theoretically, and it is found that the orientation plays a significant role in determining the particle trajectory.

Deposition of non-spherical particles in bifurcating airways
Pharmaceutical Development and Technology, 2013Particle morphology plays an important role in pulmonary drug delivery. Not only does particle shape affect how particles flow and deposit, the shape also influences the drug release rate from the particles. In this work, a semi-theoretical relationship is developed to describe deposition efficiency as a function of fluid and particle properties ...

Sintering of Non-Spherical Polyethylene Particles
Polymers and Polymer Composites, 2006Experimental observations of polymer sintering with non-spherical particles have been carried out. The evolution of neck formation during sintering was studied by two- particle experiments in a temperature-controlled oven. Shrinkage and change in surface area were also measured using image analysis.

Coarsening of non-spherical particles
Journal of Crystal Growth, 1989Abstract In this paper we analyze the coarsening of a diffuse collection of non-spherical particles. The only restriction on the particles' shapes is that each one remains in its original “shape class”. Linearized Gibbs-Thomson boundary conditions are used, and it is assumed that the particles coarsen through a quasi-static process.

Melting of non-spherical ultrafine particles
Zeitschrift für Physik D Atoms, Molecules and Clusters, 1991The behaviour of lead particles, with size up to 100 nm, embedded in a SiO matrix have been investigated versus temperature by dark field electron microscopy. When the particle is not spherical, it is shown that the melting process initiates on the surface regions of the particle where curvature is maximum.

Direct simulations of dense suspensions of non-spherical particles
International Journal of Multiphase Flow, 2011We describe the direct simulation of high-solids-fraction suspensions of non-spherical rigid particles that are slightly denser than the fluid. The lattice-Boltzmann method is used to solve the flow of the interstitial Newtonian fluid, and the immersed boundary method is used to enforce a no-slip boundary condition at the surface of each particle.

Non-spherical particles for optical trap assisted nanopatterning
Nanotechnology, 2013Optical trap assisted nanopatterning is a laser direct-write technique that uses an optically trapped microsphere as a near-field objective. The type of feature that one can create with this technique depends on several factors, one of which is the shape of the microbead.

Laser Trapping of Non-Spherical Particles [PDF]
, 2000 Optical trapping, where microscopic particles are trapped and manipulated by light is a powerful technique. The single-beam gradient trap (also known as optical tweezers) is widely used for a large number of biological and other applications. The forces and torques acting on a trapped particle result from the transfer of momentum and angular momentum ...
