“…For instance, centrifugal force is applied to detach solid materials from their concentrated suspension solution. Recently, the centrifugation technique has been used to measure the cohesion force that is developed between particles and a flat surface [16, 17]. Fundamentally, the amount of centrifugal force, which is attributed to the infiltration force, affects the morphology of the nanostructures due to augmentative quantity of infiltrated substances [17].…”

In this study, low-bandgap polymer poly{[4,4-bis(2-ethylhexyl)-cyclopenta-(2,1-b;3,4-b′)dithiophen]-2,6-diyl-alt-(2,1,3-benzothiadiazole)−4,7-diyl} (PCPDTBT) nanostructures have been synthesized via a hard nanoporous alumina template of centrifugal process. Centrifuge has been used to infiltrate the PCPDTBT solution into the nanoporous alumina by varying the rotational speeds. The rotational speed of centrifuge is directly proportional to the infiltration force that penetrates into the nanochannels of the template. By varying the rotational speed of centrifuge, different types of PCPDTBT nanostructures are procured. Infiltration force created during the centrifugal process has been found a dominant factor in tuning the morphological, optical, and structural properties of PCPDTBT nanostructures. The field emission scanning electron microscopy (FESEM) images proved the formation of nanotubes and nanowires. The energy-dispersive X-ray spectroscope (EDX) analysis showed that the nanostructures were composed of PCPDTBT with complete dissolution of the template.

“…Along with vibration and aerodynamic methods, centrifugation is one of the most efficient techniques for micrometer particle removal and for measuring adhesion forces [10][11][12][13][14][15][16][17][18][19][20][21]. In the problem of particle centrifugation, the knowledge of the rotational dynamics of particles is fundamental for understanding processes such those commonly used in industrial mixers and/or separators, fertilizer spreaders or flows under low gravity [22,23].…”

Resuspension processes in a wide range of particle sizes

et al. 2021

Particulate matter offers a broad spectrum of phenomena, well known in the granular matter community. This fact is not only related to the individual or collective behaviour that grains can present depending on the external boundary conditions and/or internal interactions but, to the wide range of particle sizes. This feature confers the possibility of studying a particular phenomenon in different size scales. The main goal of this paper is to describe the detachment of particles from surfaces, where particles go from tens of microns to several millimetres, in a variety of scenarios. All the studied systems presented here have in common the need to determine the critical conditions to lose the equilibrium balance, initiating incipient motion. Solving the right time moment for particle resuspension, consideration of the local interactions between particle, surface and external applied forces can be achieved from different modelling approaches, from deterministic dynamics to statistical mechanics. This paper focuses on some of these approaches performed recently on grains through different size scales.
