Gyroid Nanoporous Membranes with Tunable Permeability [PDF]

open access: yesACS Nano, 2011
Understanding the relevant permeability properties of ultrafiltration membranes is facilitated by using materials and procedures that allow a high degree of control on morphology and chemical composition. Here we present the first study on diffusion permeability through gyroid nanoporous cross-linked 1,2-polybutadiene (1,2-PB) membranes with uniform ...

Stress response and structural transitions in sheared gyroidal and lamellar amphiphilic mesophases: lattice-Boltzmann simulations [PDF]

open access: yes, 2006
We report on the stress response of gyroidal and lamellar amphiphilic mesophases to steady shear simulated using a bottom-up lattice-Boltzmann model for amphiphilic fluids and sliding periodic (Lees-Edwards) boundary conditions.

Experimental observation of Weyl points [PDF]

open access: yes, 2015
In 1929, Hermann Weyl derived the massless solutions from the Dirac equation - the relativistic wave equation for electrons. Neutrinos were thought, for decades, to be Weyl fermions until the discovery of the neutrino mass.

Comparison of vapor cooling characteristics of a triply periodic minimal surface and other channel geometries

open access: yesMechanical Engineering Journal, 2023
Vapor cooling shield is a key technology for long-term cryogenic propellant storage in space. Cooling channels with a triply periodic minimal surface embedded inside are expected to improve its cooling performance.

Appearance of the Single Gyroid Network Phase in Nuclear Pasta Matter [PDF]

open access: yes, 2014
Nuclear matter under the conditions of a supernova explosion unfolds into a rich variety of spatially structured phases, called nuclear pasta. We investigate the role of periodic network-like structures with negatively curved interfaces in nuclear pasta ...

Three-dimensional single gyroid photonic crystals with a mid-infrared bandgap [PDF]

open access: yes, 2016
A gyroid structure is a distinct morphology that is triply periodic and consists of minimal isosurfaces containing no straight lines. We have designed and synthesized amorphous silicon (a-Si) mid-infrared gyroid photonic crystals that exhibit a complete ...

A Bicontinuous Double Gyroid Hybrid Solar Cell [PDF]

open access: yesNano Letters, 2008
We report the first successful application of an ordered bicontinuous gyroid semiconducting network in a hybrid bulk heterojunction solar cell. The freestanding gyroid network is fabricated by electrochemical deposition into the 10 nm wide voided channels of a self-assembled, selectively degradable block copolymer film.

Direct Integration of 3D Printing and Cryogel Scaffolds for Bone Tissue Engineering

open access: yesBioengineering, 2023
Cryogels, known for their biocompatibility and porous structure, lack mechanical strength, while 3D-printed scaffolds have excellent mechanical properties but limited porosity resolution.

The geometry of the double gyroid wire network: quantum and classical [PDF]

open access: yes, 2012
Quantum wire networks have recently become of great interest. Here we deal with a novel nano material structure of a Double Gyroid wire network. We use methods of commutative and non-commutative geometry to describe this wire network.

Block copolymer self-assembly for nanophotonics [PDF]

open access: yes, 2015
The ability to control and modulate the interaction of light with matter is crucial to achieve desired optical properties including reflection, transmission, and selective polarization.
