Diamond lattices formed by atomic or colloidal elements exhibit remarkable functional properties. However, building such structures via self-assembly has proven to be challenging because of the low packing fraction, sensitivity to bond orientation, and local heterogeneity. We report a strategy for creating a diamond superlattice of nano-objects via self-assembly and demonstrate its experimental...

objective: to evaluate the efficacy of modified perihepatic packing (mphp) in reducing the rate of re-bleeding rate after packing removal. methods: this was an experimental study being performed in shiraz animal laboratory. high grade liver parenchymal injury was induced in 30 transgenic australian rabbits which were then divided into two groups. group a (control) included 14 and group b (exper...

We discuss experiments on dense packing of granular beads that are cyclically sheared quasi-statically between parallel walls under constant pressure boundary conditions. The particle positions inside the shear cell are tracked over several cycles in three dimensions using particle index-matching imaging technique. The total volume fraction of the particles φ in the cell is observed to increase...

We perform molecular dynamics simulations to compress binary hard spheres into jammed packings as a function of the compression rate R, size ratio α, and number fraction x(S) of small particles to determine the connection between the glass-forming ability (GFA) and packing efficiency in bulk metallic glasses (BMGs). We define the GFA by measuring the critical compression rate R(c), below which ...

We compare side chain prediction and packing of core and non-core regions of soluble proteins, protein-protein interfaces, and transmembrane proteins. We first identified or created comparable databases of high-resolution crystal structures of these 3 protein classes. We show that the solvent-inaccessible cores of the 3 classes of proteins are equally densely packed. As a result, the side chain...

The compressibility factor of nonassociated chain molecules composed of hard convex core Yukawa segments was derived with SAFT-VR and an extension of the Barker-Henderson perturbation theory for convex bodies. The temperature-dependent chain and dispersion compressibility factors were derived using the Yukawa potential. The effects of temperature, packing fraction, and segment number on the com...
