Particle Shape Modification in Comminution

open access: yesKONA 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

The Shape of Pulverized Bituminous Vitrinite Coal Particles

open access: yesKONA 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

The effect of alumina nanofillers size and shape on mechanical behavior of PMMA matrix composite [PDF]

open access: yesJournal 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 ...

Effect of Particle Shape on Size Segregation of Particles

open access: yesChemical Engineering Transactions, 2013
High-level control of the particle packing structure in a container requires the detailed analysis of particle size segregation during gravity filling. Here, we propose a method for analyzing quantitatively the effect of particle shape on the size segregation of particles using DEM (Distinct Element Method) simulation, which employ spherical particles ...

Effects of particle shape on mechanical performance of sand with 3D printed soil analog

open access: yesYantu gongcheng xuebao, 2020
At particle scale, the morphological characteristics have a significant effect on the mechanical responses of sand. To analyze such effect, a modified 3D shape factor S ′ is introduced to quantify the particle shape.

Shape‐Shifting Patchy Particles

open access: yesAngewandte 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.
