Computation of Implicit Representation of Volumetric Shells with Predefined Thickness

Algorithms, 2021
We propose and validate a method to find an implicit representation of a surface placed at a distance h from another implicit surface. With two such surfaces on either side of the original surface, a volumetric shell of predefined thickness can be ...

Numerical and experimental studies on compressive behavior of Gyroid lattice cylindrical shells

Materials & Design, 2020
In this paper, Gyroid lattice cylindrical shell (LCS) specimens were designed by a newly proposed mapping methodology and were fabricated by selective laser melting (SLM) technology. Their energy absorption and deformation modes were investigated through

Gyroid Nickel Nanostructures from Diblock Copolymer Supramolecules [PDF]

Journal of Visualized Experiments, 2014
Nanoporous metal foams possess a unique combination of properties - they are catalytically active, thermally and electrically conductive, and furthermore, have high porosity, high surface-to-volume and strength-to-weight ratio. Unfortunately, common approaches for preparation of metallic nanostructures render materials with highly disordered ...

Conjugate Heat Transfer and Flow Analysis of Double-Wall Cooling with Printable Gyroid-Type TPMS-Based Effusion

Aerospace
This study introduces the Gyroid structure, a type of triply periodic minimal surface (TPMS), for enhanced effusion cooling performance. Conjugate heat transfer simulations are used to compare the flow behavior, pressure loss, and overall cooling ...

A pH‐ and Light‐Responsive Nanoporous Lyotropic Gyroid Polymer Network

Advanced Materials Interfaces, 2023
Bicontinuous cubic (Q) lyotropic liquid crystal (LLC)‐derived polymer networks possess periodic, uniform‐size, 3D‐interconnected nanopores that make them highly desirable organic materials for selective molecular separation and uptake applications.

Curvature effect on nuclear pasta: Is it helpful for gyroid appearance?

, 2011
In supernova cores and neutron star crusts, nuclei are thought to deform to rodlike and slablike shapes, which are often called nuclear pasta. We study the equilibrium properties of the nuclear pasta by using a liquid drop model with curvature ...

Epitaxial Transition from Gyroid to Cylinder in a Diblock Copolymer Melt [PDF]

, 2005
An epitaxial transition from a bicontinious double gyroid to a hexagonally packed cylinder structure induced by an external flow is simulated using real-space dynamical self-consistent field technique. In order to simulate the structural change correctly,
