Ultrasonic Study of Water Adsorbed in Nanoporous Glasses
Jason Ogbebor, John J. Valenza, Peter I. Ravikovitch +6
Thermodynamic properties of fluids confined in nanopores differ from those observed in the bulk. To investigate the effect of nanoconfinement on water compressibility, we performed…
Stress-dependent normal mode frequencies from the effective mass of granular matter
Yanqing Hu, David L. Johnson, John J. Valenza +2
A zero-temperature critical point has been invoked to control the anomalous behavior of granular matter as it approaches jamming or mechanical arrest. Criticality manifests itself…
Dynamic effective mass of granular media and the attenuation of structure-borne sound
John Valenza, Chaur-Jian Hsu, Rohit Ingale +3
We report an experimental and theoretical investigation of the frequency-dependent effective mass, , of loose granular particles which occupy a rigid cavity to a give…
Dynamic effective mass of granular media
Chaur-Jian Hsu, David L. Johnson, Rohit A. Ingale +3
We develop the concept of frequency dependent effective mass, M(omega), of jammed granular materials which occupy a rigid cavity to a filling fraction of 48%, the remaining volume…
