We report the creation of a cohesive two-dimensional chiral liquid consisting of millions of spinning colloidal magnets and study its flows. We find that dissipative viscous ‘edge-pumping’ is a key and general mechanism of chiral hydrodynamics, driving unidirectional surface waves and instabilities, with no counterpart in conventional fluids …. read more: https://rdcu.be/bQGuc
Zhe Gong, Ted, Mena and Zhe Xu did a wonderful job presenting their work at the APS March meeting in Boston! Highlights below :)
Building spinning microrotors that self-assemble and synchronize to form a gear sounds like an impossible feat. However, it has now been achieved using only a single type of building block — a colloid that self-propels. Read more...
The 2nd COLLOID AND INTERFACE SYMPOSIUM 2018 is meeting at Sungkyunkwan University in Suwon, Korea. Check out the lineup at https://coins2018.weebly.com
The workshop will be held at the University of Massachusetts, Amherst from Thurs-Sat, October 26-28th 2017. The topic focuses on extracting useful action or work from systems that are driven far from equilibrium is a very exciting area of science with great potential in responsive, self-repairing, autonomous, materials.
