Optimum Size of Nanorods for Heating Application [PDF]
, 2013 Magnetic nanoparticles (MNP's) have become increasingly important in heating applications such as hyperthermia treatment of cancer due to their ability to release heat when a remote external alternating magnetic field is applied. It has been shown that the heating capability of such particles varies significantly with the size of particles used.

A novel particle tracking method with individual particle size measurement and its application to ordering in glassy hard sphere colloids [PDF]
Leocmach, M. & Tanaka, H. A novel particle tracking method with
individual particle size measurement and its application to ordering in
glassy hard sphere colloids. Soft Matter 9, 1447-1457 (2013), 2013 Particle tracking is a key to single-particle-level confocal microscopy observation of colloidal suspensions, emulsions, and granular matter. The conventional tracking method has not been able to provide accurate information on the size of individual particle.

A method to estimate the size of particles using the open source software OpenPTV [PDF]
arXiv, 2022 A method to obtain particle sizes from images that are used for particle tracking velocimetry is proposed. This is an open source method, developed to use together with the open source software OpenPTV. First, the analysis of different factors that affect the estimation of the particle size is made.

Unifying size-topology relations in random packings of dry adhesive polydisperse spheres [PDF]
Phys. Rev. E 99, 022901 (2019), 2018 We study the size-topology relations in random packings of dry adhesive polydisperse microspheres with Gaussian and lognormal size distributions through a geometric tessellation. We find that the dependence of the neighbour number on the centric particle size is always quasilinear, independent of the size distribution, the size span or interparticle ...

Effect of Particle Size on the Shear Strength Behavior of Sands [PDF]
Australian Geomechanics Journal, 2011, 2019 During plastic deformation of granular materials due to loading, the stress-strain and strength characteristics of sand grains are influenced with grain size, their distribution and packing. Also the macroscopic behaviour of granular materials changes with the variation of microscopic behaviour.

Separating micrometer-sized particles utilizing a dusty plasma ratchet [PDF]
Applied Physics Letters,123,2023, 2023 Directional transport-dominated particle separation presents major challenges in many technological applications. The Feynman ratchet can convert the random perturbation into directional transport of particles, offering innovative separation schemes.

A study of the size of snow particles in powder snow avalanches [PDF]
Annals of Glaciology 32 (2001) 258-262, 2007 In this work, we study the size of the particles involved in a powder snow avalanche phenomenon. To determine these sizes, we study all the phenomena the particles have to face before arriving in the "body" of the avalanche. We study the boundary layer which is at the bottom of the avalanche.

Porous dust grains in debris disks [PDF]
, 2013 When modeling the density and grain size distribution in debris disks, the minimum particle size is often significantly larger than the corresponding blowout size. While the dust particles are usually modeled as compact, homogenous spheres, we instead investigate the impact of porosity. The optical properties of porous particles are determined, and the

Size-independent susceptibility to transport in aeolian saltation [PDF]
arXiv, 2017 Natural wind-eroded soils contain a mixture of particle sizes. However, models for aeolian saltation are typically derived for sediment bed surfaces containing only a single particle size. To nonetheless treat natural mixed beds, models for saltation and associated dust aerosol emission have typically simplified aeolian transport either as a series of ...
