Soft double gyroids are unique, but imperfect, crystals

- What appears to be an impossibly complicated maze is actually quite simple. Two complicated mazes, intertwined but not touching, tell a different story.
Now imagine them on the nanoscale and made of soft crystals. Materials scientist Ned Thomas of Rice University's Brown School of Engineering has done more than imagine them - he and his lab have made and analyzed them, slice by nano slice.
Thomas and his team report in Nature their characterization of a soft-matter double gyroid. What they briefly thought would be a perfect double gyroid, its curving arrangement of nodes and rods repeating ad infinitum, was not to be. They found instead their hoped-for cubic construction was full of distortions.
A gyroid is a crystal based on triply periodic minimal surfaces, a geometry that allows its repeating form to spread out in three dimensions forever (or at least until constrained). They are sometimes found in nature; for instance, gyroids give butterfly wings their iridescence.
Thats my dad! He's the best.
AWESOME! Pretty legendary! :)
Hello, sorry to bother you, but could you kindly ask him for any tips on how to understand the mathematical pattern for this double gyroid? I am trying to create a 3D one on my PC.
@@courage936 did you manage? I have a MATLAB code for a 3D gyroid
I've been using gyroid infill structure on my 3D prints. I use less infill for the same stregth on the part. Saves a TON of time and also greatly reduces cost of matierial.
didn't mean to come here, but i am glad i did! thanks Ned Thomas!
Where is the paper? A link in the description would be very useful.
Is the 3D print file open to the public?
I wish I could understand this
Anyone else found this when they were looking for videos of the gyrodes from animal crossing
my goodness, pfft we'll see about that! only 230 space groups *dreams*
