Non-leachable highly luminescent ordered mesoporous SiO2 spherical particles
(Iop Publishing Ltd, 2010-04-16)
Ordered mesoporous highly luminescent SiO2 particles have been synthesized by spray pyrolysis from solutions containing tetraethylorthosilicate (TEOS) and either cetyltrimethylammonium bromide (CTAB) or the block copolymer ...
Settling velocities of particulate systems part 17. Settling velocities of individual spherical particles in Power-Law non-Newtonian fluids
(2015)
An explicit theoretical equation, compared with empirical published results, is presented to calculate the terminal settling velocities of spherical particles in Power-Law non-Newtonian fluids for Reynolds Numbers less than 1000.
Derivation and validation of a hard-body particle-wall collision model for non-spherical particles of arbitrary shape
(Elsevier, 2021-03)
In this work an extended three-dimensional model to describe the process of wall collisions of arbitrary shaped non-spherical particles is developed. This model is derived as the generalized solution of the hard-sphere ...
Non-spherical seeding 3D positioning from CCD images using Lorenz-Mie theory
(2004)
This paper describes the imaging of spherical and non-spherical particle diffraction patterns using plane-wave illumination. A discussion is presented on both the theoretical analysis of the diffraction pattern of the ...
Spinning massive test particles in cosmological and general static spherically symmetric spacetimes
(IOP Publishing, 2014)
A Lagrangian formalism is used to study the motion of a spinning massive
particle in Friedmann–Robertson–Walker and G¨odel spacetimes, as well as
in a general Schwarzschild-like spacetime and in static spherically ...
Self-consistent generalized Langevin equation theory for liquids of non-spherical brownian particles
(2015-01)
"A theoretical approach is proposed in order to describe, in the absence of hydrodynamic interactions, the equilibrium self and collective dynamics of brownian liquids conformed by non-spherical interacting particles.
As ...
Stochastic modelling for capturing the behaviour of irregular-shaped non-spherical particles in confined turbulent flows
(Elsevier, 2018-03-15)
For calculating dispersed particle-ladenflows in confined systems, the well-known Euler/Lagrange approach ismost suitable. Lagrangian tracking of non-spherical particles with certain shapes is mostly performed by addi-tionally ...
Investigation of the systems silica and silica containing chromium in alcohol medium
(Elsevier B.V., 1999-05-01)
The purpose of this work is to obtain micrometer sized spherical particles of silica and silica-chromium from sodium silicate. Spherical particles were prepared by sol-gel method from hydrolysis to polycondensation of ...
