This is due to the strong interparticle interactions that keep the particle cloud, as a whole, stationary. The charge on the particles is estimated, leading to a value of the Coulomb coupling parameter of Γ=10. This large value suggests that the particle cloud can be viewed as a Coulomb ...
The cause of such concentration dependence is, of course, interparticle interactions. In the early days of dynamic light scattering (DLS), interactions were generally regarded as a nuisance whose effects could be removed by extrapolation of data to zero concentration. Thus "free-particle" properties...
aNote that the Stokes-Einstein equation is limited to spherical, which have no interaction. At increased concentration with particle-particle interactions taking place, then an apparent particle size is obtained. If the concentration and the particle interactions are constant, then relative comparisons ...
interactions between the PEG5kand68Ga that release weakly bound68Ga from the particle during the fractionation steps. In vivo experiments revealed a similar behaviour with a rapid uptake in the lung. We suggest that this may be the result of two main factors: the size/rigidity of the particle...
is the number of ions or electrons per second represented by each model particle so that the user-defined current is obtained. Similarly, when modeling fluid-particle interactions, the volume force, , that is exerted by particles on the fluid is computed as: ...
Rheology of fine particle systems depends on many factors, particle-particle interactions being one of them. As shown by Xu and Yoon (1989, 1990), hydrophobic particles tend to coagulate in aqueous environment (Fig. 6.13). We studied such effects with the use of rheological methods. The tests...
2. One such system involves ultrafast interactions between quasi-free electrons in semiconductors3,4—which are central to high-speed and future quantum electronic devices. The femtosecond kinetics of nonequilibrium Coulomb systems has been calculated using static5,6and dynamical7,8screening models that...
For systems in which rp ≫ (1 + 1/κap), it may be assumed that the suspension is dilute enough to neglect many-body interactions (κ is the Debye reciprocal length described in Chapter 2). In order to minimize coagulation of particles prior to deposition, the electrolytes should be ...
A quantum computer that can simulate interactions between fundamental particles has been unveiled by physicists in Austria. Four trapped ions were used to model the physics that describes the creation and annihilation of electron–positron pairs. While the result can be easily calculated using a conve...
This results in a larger contribution of particle-particle interactions to the overall viscosity [13]. Second, in the case of the larger plate-like particles having a high aspect ratio, they may become aligned as the loading increases due to excluded volume interactions, which are well ...
