An accurate prediction of the settling velocities drill cuttings is essential in effectively designing, running, and optimizing drilling operations. If there no reliable process for modelling drag coefficient, velocity cannot be obtained. In most current literature, particles are assumed to spherical, which can easily modelled. However, this assumption may lead inaccurate results other irregula...

We study steady-state properties of active, nonchiral and chiral Brownian particles with polar alignment steric interactions confined within a ring-shaped confinement (annulus) in two dimensions. Exploring possible interplays between interparticle alignment, geometric the surface curvature, being incorporated here on minimal levels, we report surface-population reversal effect, whereby active m...

Understanding light scattering by nonspherical particles is crucial in modeling the transport of light in realistic structures such as biological tissues. We report the application of novel analytical approaches based on modified Wentzel-Kramers-Brillouin and equiphase-sphere methods that facilitate accurate characterization of light scattering by a wide range of irregularly shaped dielectric p...

Study characterized and analyzed form factor, elementary composition and particle size of wood dust, in order to understand its harmful health effects on carpenters in Quindío (Colombia). Once particle characteristics (size distributions, aerodynamic equivalent diameter (D(α)), elemental composition and shape factors) were analyzed, particles were then characterized via scanning electron micros...

The imidazolium-based main-chain organic polymers are one of promising platforms in heterogeneous catalysis, the size and outer morphology of polymer particles are known to have important effects on their physical properties and catalytic applications, but main-chain ionic polymers usually generate amorphous or spherical particles. Herein, we presented a versatile and facile synthetic route for...
