The bicontinuous phases, composed of two interthreaded channels separated by a matrix domain have a firm place in soft matter self-assembly, from lipids to copolymers. This post high-lights some of our recent work that shows that more complicated geometries, with three rather than two channel domains, may also result from self-assembly. Read more
Held in the picturesque Black Forest region of Germany from 7-11 September 2015, this conference will cover the mathematics and physics of disordered spatial structures and systems. Keynote speakers at this event include: Anton Bovier, Paul Chaikin, Wiebke Drenckhan, Matthew Kahle, Randall Kamien, Domenico Marinucci, Frank den Hollander and Rien van der Weygaert. We’re still accepting poster abstracts for this conference, see www.gpsrs.de
We’re still accepting abstracts for what shapes up to be an exciting international conference on real-world materials, dead and alive, with complex spatial microstructures. An interdisciplinary discussion meeting on patterns and geometry, and their role in biological and synthetic microstructured materials and tissue. We invite contributions from biology, chemistry, materials science, mathematics, physics and related fields addressing the genesis, properties and function of complex nano-scale geometries, as well as underlying geometric and topological concepts for the study of complex structure and shape. More information can be found on www.shape-up.academy. See you in Berlin! Read more
The cubic Gyroid surface is a “bicontinuous” minimal surface that divides space into two intertwined network- or labyrinth-like subdomains. The two subdomains are enantiomorphic, that is identical apart from different handedness. This animation shows a rotation of a fairly large subsection of this periodic surface, and a flight through one of the two domains. The flight path first follows a three-fold screw axis, and then turns into a four-fold screw axis. In a second run of the same animation, the same surface is shown together with the skeletal graphs that are often used to represent the Gyroid.
If you are using this animation, please reference the publication that describes it: Hyde & Schröder-Turk, Geometry of interfaces: topological complexity in biology and materials, Interface Focus 2(5), 529-538 (2012)
This animation was produced at the ANU during my PhD. Special thanks to Stuart Ramsden for a lot of help!
