Structural Color 3D Printing By Shrinking Photonic Crystals [PDF]

, 2019
The rings, spots and stripes found on some butterflies, Pachyrhynchus weevils, and many chameleons are notable examples of natural organisms employing photonic crystals to produce colorful patterns.

Investigation of functionally graded TPMS structures fabricated by additive manufacturing

Materials & Design, 2019
Triply periodic minimal surfaces (TPMS), which have zero mean curvature and large surface areas, are discussed in this paper. Two TPMS structures, the Schwarz Primitive (P) and Gyroid, were designed with both uniform and graded density and fabricated ...

Weyl points and line nodes in gapless gyroid photonic crystals

, 2012
Weyl points and line nodes are three-dimensional linear point- and line-degeneracies between two bands. In contrast to Dirac points, which are their two-dimensional analogues, Weyl points are stable in the momentum space and the associated surface states

Icosahedral packing of polymer-tethered nanospheres and stabilization of the gyroid phase

, 2007
We present results of molecular simulations that predict the phases formed by the self-assembly of model nanospheres functionalized with a single polymer "tether", including double gyroid, perforated lamella and crystalline bilayer phases.

Bending Frustration of Lipid-Water Mesophases Based on Cubic Minimal Surfaces [PDF]

, 2001
Inverse bicontinuous cubic phases are ubiquitous in lipid-water mixtures and consist of a lipid bilayer forming a cubic minimal surface, thereby dividing space into two cubic networks of water channels. For small hydrocarbon chain lengths, the monolayers

Spatially distributed and interconnected porous architectures for dental implants

International Journal of Implant Dentistry
Purpose Patients with pre-existing medical conditions that impair bone integrity face challenges in dental implant success due to compromised osseointegration. This study evaluates three titanium interconnected porous architectures: the TPMS solid gyroid,

Geometry of the momentum space: From wire networks to quivers and monopoles [PDF]

, 2013
A new nano--material in the form of a double gyroid has motivated us to study (non-commutative $C^*$ geometry of periodic wire networks and the associated graph Hamiltonians.

Structural transitions and arrest of domain growth in sheared binary immiscible fluids and microemulsions [PDF]

, 2007
We investigate spinodal decomposition and structuring effects in binary immiscible and ternary amphiphilic fluid mixtures under shear by means of three dimensional lattice Boltzmann simulations.
