A Study of the Occurrence of Supercooling of Water
K. -C. Tan, W. Ho, J. I. Katz +1
Supercooling of water can be easily studied with a simple apparatus suitable for the student laboratory. We describe such an apparatus and its capabilities. The parameters influenc…
Rheology in the Teaching Lab: Properties of Starch Suspensions
Joel A. Groman, James G. Miller, Jonathan I. Katz
In everyday life we encounter many complex fluids, from shear-thinning paint and toothpaste to shear-thickening starch suspensions. The study of their properties offers an opportun…
Hysteresis and Lubrication in Shear Thickening of Cornstarch Suspensions
Clarence E. Chu, Joel A. Groman, Hannah L. Sieber +3
Aqueous and brine suspensions of corn starch show striking discontinuous shear thickening. We have found that a suspension shear-thickened throughout may remain in the jammed thick…
Ultrasonic Attenuation and Speed of Sound of Cornstarch Suspensions
Benjamin L. Johnson, Mark R. Holland, James G. Miller +1
The goal of this study is to contribute to the physics underlying the material properties of suspensions that exhibit shear thickening through the ultrasonic characterization of su…
Effective medium theory of elastic waves in random networks of rods
J. I. Katz, J. J. Hoffman, M. S. Conradi +1
We formulate an effective medium (mean field) theory of a material consisting of randomly distributed nodes connected by straight slender rods, hinged at the nodes. Defining novel…
Viscoelastic Suppression of Gravity-Driven Counterflow Instability
P. Beiersdorfer, D. Layne, E. W. Magee +1
Attempts to achieve "top kill" of actively flowing oil wells by insertion of dense drilling "muds", i.e., slurries of dense minerals, from above will fail if the Kelvin-Helmholtz i…
When hot water freezes before cold
J. I. Katz
I suggest that the origin of the Mpemba effect (the freezing of hot water before cold) is freezing-point depression by solutes, either gaseous or solid, whose solubility decreases…
Atomistics of Tensile Failure in Fused Silica: Weakest Link Models Revisited
J. I. Katz
In weakest link models the failure of a single microscopic element of a brittle material causes the failure of an entire macroscopic specimen, just as a chain fails if one link fai…
