Translational and rotational friction on a colloidal rod near a wall.
We present particulate simulation results for translational and rotational friction components of a shish-kebab model of a colloidal rod with aspect ratio (length over diameter) L/D=10 in the presence of a planar hard wall. Hydrodynamic interactions between rod and wall cause an overall enhancement of the friction tensor components. We find that the friction enhancements to reasonable approxima...
متن کاملTranslational and Rotational Friction of Lactodendrimer Molecules in Solutionl
The samples of fir'e hybrid dendrimer (lactopolypropylene imine) generations were studied by the methods of molecular hydrod-vnamics, including the sedimentation velocity. translationa] diffusion, and intrinsic viscosity measurement s in 0.l65Vo aqueous NaCl solutions. The molecular masses (1.9 < M sDx 10-3 < 46.5) and the corresponding hydrodynamic dimensions of the dendrimer molecules were de...
متن کاملDecoupling of rotational and translational diffusion in supercooled colloidal fluids.
We use confocal microscopy to directly observe 3D translational and rotational diffusion of tetrahedral clusters, which serve as tracers in colloidal supercooled fluids. We find that as the colloidal glass transition is approached, translational and rotational diffusion decouple from each other: Rotational diffusion remains inversely proportional to the growing viscosity whereas translational d...
متن کاملPair interaction of charged colloidal spheres near a charged wall.
Although equally charged colloidal particles dispersed in clean water are expected to repel each other, an unexplained long-range attraction has consistently been reported for charged colloidal spheres confined by charged macroscopic surfaces. We present an alternative equilibrium measurement of the pair interaction energy for charged spheres near a single charged wall. Analyzing their radial d...
متن کاملa study on rate making and required reserves determination in reinsurance market: a simulation
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
