Short-range forces refer to those interactions that occur at a particle separation distance of less than 1–2 nm, whereas long-range interaction forces among particles refer to those interactions that occur at a particle separation distance ranged approximately from 5–100 nm. Long-range forces ...
On a similar note, what about particle-particle interaction, I'll be considering linear elastic interactions. Let's say for the sake of the argument, two A cells have a k value of 10 N/m while a A-B cell interaction have 2 N/m, How can I apply this on COMSOL? Thanks in advan...
Currently, PEPT is restricted to industrial applications such as the evaluation of particle–fluid or particle–particle interactions in the pharmaceutical, chemical, oil, mining, construction and power generation industries, among others2,3,4. Due to the extraordinary spatiotemporal resolution of PEPT,...
Interaction between two different species of particles in a fluid stream is promoted by generating turbulent eddies in the fluid stream. The turbulent eddies are designed to be of such size and/or intensity that the two species of particles are entrained into the eddies to significantly different ...
Particle velocities were measured in a solid-liquid suspension of polv-sized particles at solids concentrations of 1.6–3.6% v/v. The results of these experiments indicated that particle-particle interactions may play an important role in determining the velocities of the separate particles in the ...
The fundamental properties of a plasma depend upon the interactions between the plasma particles and the existing force fields. These fields may be externally applied or they can be internal fields associated with the nature and motion of the particles themselves. In this text the words collision ...
Undesirable protein-protein interactions (PPI) can lead to self-association and/or high solution viscosity in concentrated protein formulations that are typically greater than 50 mg/mL. Therefore, understanding the effects of excipients on nonspecific PPI is important for Disentangling the role of ...
Electrostatic coupling between particles is important in many microscopic phenomena found in nature. The interaction between two isolated point charges is described by the bare Coulomb potential, but in many-body systems this interaction is modified as a
Learn about the new efficient and self-consistent approach to modeling particle-field and fluid-particle interactions available in COMSOL 4.4
We present direct measurements of particle–particle and particle–surface interactions in the gas phase carried out with an atomic force microscope (AFM). Special emphasis is given to a proper statistical treatment of the data. For modelling of particle adhesion, we use computer-assisted empirical ...
