Physical Review E, 1998
We investigate the entropic depletion force that arises between two big hard spheres of radius ${R}_{b},$ mimicking colloidal particles, immersed in a fluid of small hard spheres of radius ${R}_{s}.$ Within the framework of the Derjaguin approximation, which becomes exact as ${s=R}_{s}{/R}_{b}\ensuremath{\rightarrow}0$, we examine an exact expression ...

The traditional method of determining the forces induced on structural elements has been to consider the force to be due to linear combination of an inertial contribution and a drag contribution, or FT = FI + FD Each of these time-varying components has then been formulated in terms of (i) geometrical properties of the structure, (ii) fluid properties ...

Forced Rayleigh Experiment in a Magnetic Fluid
Physical Review Letters, 1995A spatial modulation of colloidal concentration of nanoscopic magnetic particles is written in a ferrofluid solution inside the fringes of a forced Rayleigh scattering device. The relaxation time of this transient grating is inversely proportional to the square of the characteristic wave vector and thus to the cooperative diffusion coefficient of ...

In the previous chapter, we looked in some detail at gravity, which is a force that acts at a distance. Except for gravity, however, most of the forces that we encounter in our daily lives arise from direct contact with other objects, either solids or fluids.

Pair force distributions in simple fluids
The Journal of Chemical Physics, 2011Analytic expressions are derived for the frequency distribution, P(f), of pair forces, f, and those of their α-Cartesian component, fα, or P(fα), for some typical model simple fluids, expressed in terms of the radial distribution function and known constants. For strongly repulsive inverse power (IP), exponential and Yukawa purely repulsive potentials,

Point force in a MHB rotating fluid
Applied Scientific Research, 1977We consider the steady flow of an inviscid, rotating fluid confined in a cylinder under the influence of a uniform axial magnetic field, in the presence of an isolated point force. It is found that, the wave-like terms, infinite in number, occurring on the downstream side are not persistent and decay at far distances, in contrast to the non-magnetic ...

Forced capillary wetting of viscoelastic fluids
Journal of Colloid and Interface ScienceAchieving rapid capillary wetting is highly desirable in nature and industries. Previous endeavors have primarily concentrated on passive wetting strategies through surface engineering. However, these approaches are inadequate for high-viscosity fluids due to the significant viscous resistance, especially for non-Newtonian fluids.

Forces and Fluids in the Essay
2018The term force is one of the most widely employed in the Essay, more than two hundred and fifty times, only surpassed by the word pressure. Considering d’Alembert’s warning that he would only use the word force in order to avoid circumlocution, this repetition seems somewhat surprising.

Quantification of intercellular adhesion forces measured by fluid force microscopy
Talanta, 2017The mechanics of cancer cell adhesion to its neighboring cells, homotypic or heterotypic, have significant impact on tumor progression and metastasis. Intercellular adhesion has been quantified previously using atomic force microscopy-based methods. Here we show the feasibility of the recently developed fluidic force microscopy (FluidFM) to measure ...
