TLDR
Low Reynolds number flow theory finds wide application in such diverse fields as sedimentation, fluidization, particle-size classification, dust and mist collection, filtration, centrifugation, polymer and suspension rheology, and a host of other disciplines.Abstract:
Low Reynolds number flow theory finds wide application in such diverse fields as sedimentation, fluidization, particle-size classification, dust and mist collection, filtration, centrifugation, polymer and suspension rheology, flow through porous media, colloid science, aerosol and hydrosal technology, lubrication theory, blood flow, Brownian motion, geophysics, meteorology, and a host of other disciplines. This text provides a comprehensive and detailed account of the physical and mathematical principles underlying such phenomena, heretofore available only in the original literature.read more

Breakdown of the Continuum Stokes−Einstein Relation for Nanoparticle Diffusion
TL;DR: This is one of the first demonstrations of X-ray photo correlation spectroscopy applied to polymeric liquids, which is used to explain the simultaneous 60% viscosity reduction of the mixture through a proposed constraint release mechanism.
Journal ArticleDOI
Measurement of small forces using an optical trap
TL;DR: In this paper, a simple and sensitive method for detecting small forces applied to an optically trapped microsphere utilizes the transmitted beam of the trapping laser to monitor micro-sphere deflections within the potential well of the trap.

Rotational friction coefficients for ellipsoids and chemical molecules with the slip boundary condition
G. K. Youngren,A. Acrivos +1 more
TL;DR: In this paper, the authors employed a more realistic shape for benzene and found a difference of 10%, which is within the limits of the numerical and experimental uncertainty, for a benzene molecule rotating normal to its axis of symmetry.
Journal ArticleDOI
Photonic force microscope calibration by thermal noise analysis
TL;DR: In this paper, the forces of a photonic force microscope based on optical tweezers are determined using the Boltzmann dis- tribution of thermally driven position fluctuations, where only a minimum of information about the system is required, i.e. the solution's temperature.
Journal ArticleDOI
A new continuum model for suspensions of gyrotactic micro-organisms.
TL;DR: The continuum model for small epsilon is used to reanalyse the instability of a uniform suspension and it is demonstrated that the only significant contribution to sigma is that derived from the stresslets associated with the cells' intrinsic swimming motions.
