Journal of Colloid and Interface Science, 1997
We use Brakke's Surface Evolver to construct a family of intersection-free triply periodic surfaces with constant mean curvature. The gyroid family models various physical interfaces. We calculate area and volume along the family, compare it with the Schwarz P and D families, and discuss the general problem of a comparison of triply periodic ...

Gyroidal Metal–Organic Frameworks
Journal of the American Chemical Society, 2011The gyroid is ubiquitous for underlying the construction of natural substance and artificial zeolites, but it has been, surprisingly, overlooked by chemists who work in the field of metal-organic frameworks (MOFs). In this work, a series of gyroidal MOFs with gie topology, constructed from 1,2-bis((5H-imidazol-4-yl)methylene)hydrazine and octahedral ...

Nonclassical Chiral Elasticity of the Gyroid Lattice
Physical Review Letters, 2020The gyroid lattice is a metamaterial which allows chirality that is tunable by geometry. Gyroid lattices were made in chiral and nonchiral form by 3D printing. The chiral lattices exhibited nonclassical elastic effects including coupling between compressive stress and torsional deformation.

The stiffness and strength of the gyroid lattice
International Journal of Solids and Structures, 2014 AbstractRecently, a nanoscale lattice material, based upon the gyroid topology has been self-assembled by phase separation techniques (Scherer et al., 2012) and prototyped in thin film applications. The mechanical properties of the gyroid are reported here.

Physica A: Statistical Mechanics and its Applications, 1998
Abstract The unusual gyroid phase is described in three different amphiphilic systems. The way in which its existence can be understood in terms of surfaces of constant mean curvature is reviewed, as is the manner in which it can actually be accounted for by standard models of diblock copolymers solved within self-consistent field theory.

On the Origin of Chirality in Nanoplasmonic Gyroid Metamaterials
Advanced Materials, 2012Metallic single gyroids, a new class of self-assembled nanoplasmonic metamaterials, are analyzed on the basis of a tri-helical metamaterial model. The physical mechanisms underlying the chiral optical behavior of the nanoplasmonic single gyroid are identified and it is shown that the optical chirality in this metallic structure is primarily determined ...

Kinetic pathway to double-gyroid structure
The Journal of Chemical Physics, 2005We have investigated the structural development during order-order transitions to the double-gyroid (DG) phase of nonionic surfactant/water systems based on two-dimensional small-angle x-ray scattering patterns from highly oriented ordered mesophases.

Metallic gyroids with broadband circular dichroism
Optics Letters, 2018Circular dichroism is a useful property for filtering or separating beams containing opposite spin angular momentum. Of the many geometries exhibiting circular dichroism, the gyroid has proven to be an excellent template for exploring circular dichroism in three dimensions.

Enhanced Electrochromism in Gyroid‐Structured Vanadium Pentoxide
Advanced Materials, 2012Manufacturing V(2)O(5) in a 3D periodic highly interconnected gyroid structure on the 10 nm length scale is shown to lead to a significant electrochromic performance enhancement. The structured devices surpass previous inorganic electrochromic materials in all relevant parameters: the switching speed, coloration contrast, and composite coloration ...
