Packing problems have been a source of fascination for millenia and their study has produced a rich literature that spans numerous disciplines. Investigations of hard-particle packing models have provided basic insights into the structure and bulk properties of condensed phases of matter, including low-temperature…

Particle shape plays a crucial role in determining packing characteristics. Real particles in nature usually have rounded corners. In this work, we systematically investigate the rounded corner effect on the dense packings of spherotetrahedral particles. The evolution of dense packing structure as the particle shape…

We have recently devised organizing principles to obtain maximally dense packings of the Platonic and Archimedean solids, and certain smoothly-shaped convex nonspherical particles [Torquato and Jiao, Phys. Rev. E 81, 041310 (2010)]. Here we generalize them in order to guide one to ascertain the densest packings of…

Jammed Packings of Hard Spherocylinders with a Low Aspect Ratio: A Characterization of Their Structure Authors: ['Hugo Imaz González' 'Giorgio Cinacchi'] This work numerically investigates dense disordered (maximally random) jammed packings of hard spherocylinders of cylinder length L and diameter D by focusing on L/D…

Dense arrangements of binding sites within nucleotide sequences can collectively influence downstream transcription rates or initiate biomolecular interactions. For example, natural promoter regions can harbor many overlapping transcription factor binding sites that influence the rate of transcription initiation.…

We revisit the densest binary sphere packings (DBSP) under the periodic boundary conditions and present an updated phase diagram, including newly found 12 putative densest structures over the x−α plane, where x is the relative concentration and α is the radius ratio of the small and large spheres. To efficiently…

The study of hard-particle packings is of fundamental importance in physics, chemistry, cell biology, and discrete geometry. Much of the previous work on hard-particle packings concerns their densest possible arrangements. By contrast, we examine kinetic effects inevitably present in both numerical and experimental…

'Jason Christopher Jolly' 'Hong Suk Kang' 'Jin Hong Lee' 'Junsoo Kim' 'Seung Hwan Lee' 'Albert S. Lee' 'Soon Man Hong' 'Cheolmin Park' 'Shu Yang' 'Chong Min Koo'] Designing topographic clusters is of significant interest, yet it remains challenging as they often lack mobility or deformability. Here we exploit the huge…

Packings of identical objects have fascinated both scientists and laymen alike for centuries, in particular the sphere packings and the packings of identical regular tetrahedra. Mathematicians have tried for centuries to determine the densest packings; Crystallographers and chemists have been fascinated by the lattice…

High strength-to-weight ratio materials can be constructed by either maximizing strength or minimizing weight. Tensegrity structures and aerogels take very different paths to achieving high strength-to-weight ratios but both rely on internal tensile forces. In the absence of tensile forces, removing material eventually…

We present a simple yet efficient random (brute-force) algorithm for constructing solvated molecular systems. By placing solvent molecules at random positions and orientations within a simulation box, we circumvent the complexities typically associated with more sophisticated packing algorithms. The main computational…

The regulation of mechanotransduction is crucial for various cellular processes, including stem cell differentiation, wound healing, and cancer progression. While the activation of mechanotransduction has been extensively studied in single cells, it remains unclear whether similar mechanisms extend to…

The coordination of cell proliferation, migration, and differentiation is crucial for organogenesis in many tissues, including the central nervous system and other organs that arise from pseudostratified epithelia (PSE). PSE feature densely packed elongated epithelial cells, with nuclei positioned along the apicobasal…

Great progress has been made in understanding the atomic structure of metallic glasses, but there is still no clear connection between atomic structure and glass-forming ability. Here we give new insights into perhaps the most important question in the field of amorphous metals: how can glass-forming ability be…

Single-molecule localization microscopy (SMLM) enables nanoscale imaging but remains limited in three-dimensional (3D), high-speed, and high-density applications due to background fluorescence, photon inefficiency, and large point-spread function (PSF) footprints. Here, we present single-objective light-sheet…

Organic molecules tend to close pack to form dense structures when they are crystallized from organic solvents. Porous molecular crystals defy this rule: they typically crystallize with lattice solvent in the interconnected pores. However, the design and discovery of such structures is often challenging and time…

The ambient-pressure dl-menthol polymorph α compressed above 0.40 GPa becomes metastable but more dense than the high-pressure polymorph β.

A direct way to spot structural features that are universally shared among proteins is to find proper analogues from simpler condensed matter systems. In most cases, sphere-packing arguments provide a straightforward route for structural comparison, as they successfully characterize a wide array of materials such as…

Despite advances in crystal engineering, predicting the packing of metal-containing molecules remains a significant challenge due to their increased structural complexity and computational cost relative to purely organic compounds. Yet, predicting solid-state structures is critical for understanding structure-property…

From crystal chemistry rationale and geometry optimization onto ground state structures with DFT-based computations, a novel ultra-hard body centered tetragonal C4 (tet-C4) is proposed as the simplest dense carbon allotrope. tet-C4 is identified as cohesive as diamond, and likewise built of corner sharing C4 tetrahedra…

In scientific disciplines, benchmarks play a vital role in driving progress forward. For a benchmark to be effective, it must closely resemble real-world tasks. If the level of difficulty or relevance is inadequate, it can impede progress in the field. Moreover, benchmarks should have low computational overhead to…

How molecules pack has vital ramifications for their applications as functional molecular materials. Small changes in a molecule’s functionality can lead to large, non-intuitive, changes in their global solid-state packing, resulting in difficulty in targeted design. Predicting the crystal structure of organic…
