Non-spherical particles in optical tweezers: A numerical solution
PLOS ONE, 2019 We present numerical methods for modeling the dynamics of arbitrarily shaped particles trapped within optical tweezers, which improve the predictive power of numerical simulations for practical use. We study the dependence of trapping on the shape and size of particles in a single continuous wave beam setup.

Non-spherical particle mixing behaviors by spherical inert particles assisted in a fluidized bed
Petroleum Science, 2019 Fluidized beds are widely used in many industrial fields such as petroleum, chemical and energy. In actual industrial processes, spherical inert particles are typically added to the fluidized bed to promote fluidization of non-spherical particles ...

Enhanced Septahedral Ordering in Cold Lennard-Jones Fluids [PDF]
, 2005 We report molecular dynamics calculations on two-component, cold (1.2 > T > 0.56 in natural units), three-dimensional Lennard-Jones fluids. Our system was small (7813 A, 7812 B particles), dense (N/V = 1.30), and distinctly finite (L \times L \times L ...

Volcanic ash infrared signature: porous non-spherical ash particle shapes compared to homogeneous spherical ash particles [PDF]
Atmospheric Measurement Techniques, 2014 The reverse absorption technique is often used to detect volcanic ash clouds from thermal infrared satellite measurements. From these measurements effective particle radius and mass loading may be estimated using radiative transfer modelling.

The decay law can have an irregular character [PDF]
, 2006 Within a well-known decay model describing a particle confined initially within a spherical $\delta$ potential shell, we consider the situation when the undecayed state has an unusual energy distribution decaying slowly as $k\to\infty$; the simplest ...

Calculation and optical measurement of laser trapping forces on non-spherical particles [PDF]
, 2001 Optical trapping, where microscopic particles are trapped and manipulated by light is a powerful and widespread technique, with the single-beam gradient trap (also known as optical tweezers) in use for a large number of biological and other applications.
