Particle Shape Modification in Comminution
KONA Powder and Particle Journal, 2014 The evolution of particle shape during the course of comminution processes has been investigated. Shape is characterized using a variety of quantitative shape descriptors determined from particle profiles obtained by

Shape matters: Competing mechanisms of particle shape segregation
Physical Review E, 2022 It is well-known that granular mixtures that differ in size or shape segregate when sheared. In the past, two mechanisms have been proposed to describe this effect, and it is unclear if both exist. To settle this question, we consider a bidisperse mixture of spheroids of equal volume in a rotating drum, where the two mechanisms are predicted to act in ...

The Shape of Pulverized Bituminous Vitrinite Coal Particles
KONA Powder and Particle Journal, 2014 The shape of pulverized bituminous coal particles (vitrinites) was determined by optical and laser light scattering. Vitrain samples were collected from obvious tree remains located in the ceilings of two Appalachian

Effect of particle shape and fragmentation on the response of particle dampers [PDF]
, 2013 A particle damper (PD) is a device that can attenuate mechanical vibrations thanks to the dissipative collisions between grains contained in a cavity attached to the vibrating structure.

The effect of alumina nanofillers size and shape on mechanical behavior of PMMA matrix composite [PDF]
Journal of the Serbian Chemical Society, 2014 Composites with the addition of alumina nanofillers show improvement in mechanical properties. The PMMA polymer was used as a matrix and two different types of nanofillers, having extremely different shapes were added in the matrix to form the ...

Shape formation by programmable particles [PDF]
Distributed Computing, 2019 Shape formation is a basic distributed problem for systems of computational mobile entities. Intensively studied for systems of autonomous mobile robots, it has recently been investigated in the realm of programmable matter. Namely, it has been studied in the geometric Amoebot model, where the anonymous entities, called particles, operate on a ...

Shape‐Shifting Patchy Particles
Angewandte Chemie International Edition, 2017 AbstractA facile method to synthesize shape‐shifting patchy particles on the colloidal scale is described. The design is based on the solvent‐induced shifting of the patch shape between concave and convex features. The initial concave patchy particles were synthesized in a water suspension by a swelling‐induced buckling process.
