Force network ensemble for the triangular lattice: A tale of tiles [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2009
In granular materials, contact forces between neighboring grains are organized in disordered force networks. At present, it is unclear whether or not theories based on statistical mechanics can correctly predict the statistics of these force networks. The force network ensemble is a convenient model system for studying force networks.

Experimental study of cooling tower performance using ceramic tile packing [PDF]

open access: yesProcessing and Application of Ceramics, 2013
Deterioration of the packing material is a major problem in cooling towers. In this experimental study ceramic tiles were used as a packing material. The packing material is a long life burnt clay, which is normally used as a roofing material.

Non-Local Game of Life in 2D Quasicrystals

open access: yesCrystals, 2018
On a two-dimensional quasicrystal, a Penrose tiling, we simulate for the first time a game of life dynamics governed by non-local rules. Quasicrystals have inherently non-local order since any local patch, the emperor, forces the existence of a large ...

Moiré-Tile Manipulation-Induced Friction Switch of Graphene on a Platinum Surface [PDF]

open access: yes, 2023
Friction control and technological advancement are intimately intertwined. Concomitantly, two-dimensional materials occupy a unique position for realizing quasi-frictionless contacts.

Surface mosaics [PDF]

open access: yes, 2006
This paper considers the problem of placing mosaic tiles on a surface to produce a surface mosaic. We assume that the user specifies a mesh model, the size of the tiles and the amount of grout, and optionally, a few control vectors at key locations ...

Direct Atomic Force Microscopy Observation of DNA Tile Crystal Growth at the Single-Molecule Level [PDF]

open access: yesJournal of the American Chemical Society, 2012
While the theoretical implications of models of DNA tile self-assembly have been extensively researched and such models have been used to design DNA tile systems for use in experiments, there has been little research testing the fundamental assumptions of those models.
