Processing carbon nanotubes with holographic optical tweezers
Joseph Plewa, Evan Tanner, Daniel M. Mueth +1
We report the first demonstration that carbon nanotubes can be trapped and manipulated by optical tweezers. This observation is surprising because individual nanotubes are substant…
Measurements of Particle Dynamics in Slow, Dense Granular Couette Flow
Daniel M. Mueth
Experimental measurements of particle dynamics on the lower surface of a 3D Couette cell containing monodisperse spheres are reported. The average radial density and velocity profi…
Signatures of granular microstructure in dense shear flows
Daniel M. Mueth, Georges F. Debregeas, Greg S. Karczmar +3
Granular materials react to shear stresses differently than do ordinary fluids. Rather than deforming uniformly, materials such as dry sand or cohesionless powders develop shear ba…
Memory Effects in Granular Material
Christophe Josserand, Alexei Tkachenko, Daniel M. Mueth +1
We present a combined experimental and theoretical study of memory effects in vibration-induced compaction of granular materials. In particular, the response of the system to an ab…
Compaction of Rods: Relaxation and Ordering in Vibrated, Anisotropic Granular Material
Fernando X. Villarruel, Benjamin E. Lauderdale, Daniel M. Mueth +1
We report on experiments to measure the temporal and spatial evolution of packing arrangements of anisotropic, cylindrical granular material, using high-resolution capacitive monit…
Force Distribution in a Granular Medium
Daniel M. Mueth, Heinrich M. Jaeger, Sidney R. Nagel
We report on systematic measurements of the distribution of normal forces exerted by granular material under uniaxial compression onto the interior surfaces of a confining vessel.…
