Journal ArticleDOI
Instabilities in a sandpile
TL;DR: In this article, it is shown that sand behaves in a manner more reminiscent of a first-order transition than of a second-order one, which is not consistent with self-organized criticality.
Journal ArticleDOI
Sound in sand
Chu-heng Liu,Sidney R. Nagel +1 more
TL;DR: It is found that the vibrations in a granular material are qualitatively different from those found in solids or liquids, reminiscent of conductance fluctuations in mesoscopic metals.
Journal ArticleDOI
Wide‐frequency specific heat spectrometer
Norman O. Birge,Sidney R. Nagel +1 more
TL;DR: In this paper, the frequency-dependent specific heat of a liquid over a frequency range exceeding five decades, 0.01-3000 Hz, was measured using a planar heater.
Journal ArticleDOI
The inexorable resistance of inertia determines the initial regime of drop coalescence
Joseph D. Paulsen,Justin Burton,Sidney R. Nagel,Santosh Appathurai,Michael T. Harris,Osman A. Basaran +5 more
TL;DR: It is revealed that a third regime, one that describes the initial dynamics of coalescence for all drop viscosities, has been missed and an argument based on force balance allows the construction of a new coalescence phase diagram.
Journal ArticleDOI
Frequency-dependent specific heat and thermal conductivity at the glass transition in o-terphenyl mixtures.
Paul K. Dixon,Sidney R. Nagel +1 more
TL;DR: Les mesures de chaleur massique et de conductivite thermique en fonction de la frequence sont faites sur (ortho-terphenyle) 1−x (orthO-phenyl-phenole) x avec x=0,09,0,16, 0,22 et 0,33 pres de la transition vitreuse.
