Random close packing in protein cores
Jennifer C. Gaines, W. Wendell Smith, Lynne Regan +1
Shortly after the determination of the first protein x-ray crystal structures, researchers analyzed their cores and reported packing fractions , a value that is simi…
Beyond packing of hard spheres: The effects of core softness, non-additivity, intermediate-range repulsion, and many-body interactions on the glass-forming ability of bulk metallic glasses
Kai Zhang, Meng Fan, Yanhui Liu +3
When a liquid is cooled well below its melting temperature at a rate that exceeds the critical cooling rate , the crystalline state is bypassed and an amorphous glassy state f…
Magnetic alignment of block copolymer microdomains by intrinsic chain anisotropy
Yekaterina Rokhlenko, Kai Zhang, Manesh Gopinadhan +6
We examine the role of intrinsic chain susceptibility anisotropy in magnetic field directed self-assembly of a block copolymer using \textit{in situ} X-ray scattering. Alignment of…
Protocol dependence of the jamming transition
T. Bertrand, R. P. Behringer, B. Chakraborty +2
We propose a theoretical framework for predicting the protocol dependence of the jamming transition for frictionless spherical particles that interact via purely repulsive contact…
Experiments demonstrate that the null space of the rigidity matrix determines grain motion during vibration-induced compaction
A. Hubard, C. S. O'Hern, M. D. Shattuck
Using a previously developed experimental method to reduce friction in mechanically stable packings of disks, we find that frictional packings form tree-like structures of geometri…
On the origin of multi-component bulk metallic glasses: Atomic size mismatches and de-mixing
K. Zhang, B. Dice, Y. Liu +3
The critical cooling rate , below which liquids crystallize upon cooling, characterizes the glass-forming ability (GFA) of the system. While pure metals are typicall…
