Particle force

A magnetic field exerts a force on each of the two poles of a dipole (particle), forcing it to ahgn itself with the hnes of magnetic force. 

It should be clear that force field methods are models of the real quantum mechanical systems. The total neglect of electrons as individual particles forces the user to define explicitly the bonding present in the molecule prior to any calculations. The user must decide how to describe a given molecule in terms of the selected force field. The input to a calculation consists of three sets of information. 

From the continuity and momentum equations for the fluid and solid phases along with the boundary conditions, the following groups of independent dimensionless parameters are found to control the hydrodynamics, noting our assumption that the particle-particle forces are only dependent on hydrodynamic parameters,...

In FFF systems, the separation along the flow axis is caused by the perpendicular field, whose crucial role is recognized by the word "field" 1n field-flow fractionation. The applied field Interacts with entrained particles, forcing them to accumulate at one wall (the accumulation wall) of the channel. Since the flow velocity near any wall is reduced by frictional drag, the downstream displacement of the particles 1s retarded. Retardation (or retention) is greatest for those particles forced most closely to the wall. Consequently, particles are separated according to the different forces exerted on them by the applied field. These forces normally depend on particle size, leading to a size-based separation. 

In several cases, however, the DLVO-theory has shown to be inadequate, due to the occurrence of other inter-particle forces that may be present in colloidal suspensions. These phenomena are summed up below ... 

The Monte Carlo simulation of Brownian coagulation involves the evaluation of the ensemble average of the coagulation rate over a large number of particle pairs, through the generation of particle trajectories. The inter-particle forces due to the van der Waals attraction and Born repulsion are accounted for in the description of the relative motion [40] two Particles. The relative Brownian motion of two particles is described by the... 

Aggregation because of strong inter-particle forces, originated by an excess of surface free energy, nanoparticles may easily aggregate. When hydrophobic they will clump together in polar/aqueous media such as any body fluid. This may be inconvenient with animal tests as such clumped material will not disperse,14 and in some cases even cause immediate animal death.15...
