The odd free surface flows of a colloidal chiral fluid
Vishal Soni,Ephraim Bililign,Sofia Magkiriadou,Sofia Magkiriadou,Stefano Sacanna,Denis Bartolo,Michael Shelley,William T. M. Irvine +7 more
TL;DR: In this article, a two-dimensional chiral liquid consisting of millions of spinning colloidal magnets was created and its flows were studied, and it was shown that dissipative viscous "edge-pumping" is a key and general mechanism of chiral hydrodynamics, driving unidirectional surface waves and instabilities.

Full‐Spectrum Photonic Pigments with Non‐iridescent Structural Colors through Colloidal Assembly
Jin-Gyu Park,Shin-Hyun Kim,Sofia Magkiriadou,Tae Min Choi,Youngseok Kim,Vinothan N. Manoharan +5 more
TL;DR: It is shown that the design of the microcapsules facilitates the suppression of incoherent and multiple scattering, enabling the fabrication of photonic pigments with colors spanning the visible spectrum, providing new insights into the design and synthesis of materials with structural colors.
Absence of red structural color in photonic glasses, bird feathers, and certain beetles.
TL;DR: Using scattering theory, it is shown that the absence of angle-independent red color can be explained by the tendency of individual particles to backscatter light more strongly in the blue, and the model is used to develop design rules for colloidal glasses with red, angle- independent structural colors.
Inverse Photonic Glasses by Packing Bidisperse Hollow Microspheres with Uniform Cores
Seung-Hyun Kim,Seung-Hyun Kim,Sofia Magkiriadou,Sofia Magkiriadou,Do Kyung Rhee,Do Kyung Rhee,Doo Sung Lee,Doo Sung Lee,Pil J. Yoo,Pil J. Yoo,Vinothan N. Manoharan,Vinothan N. Manoharan,Gi-Ra Yi,Gi-Ra Yi +13 more
TL;DR: A binary mixture of 246 and 268 nm hollow silica particles with 180 nm cores in an index-matched polymer matrix achieves angle-independent red color that can be tuned by controlling the shell thickness, which can be kept constant, even for larger interparticle distances.
Effects of multiple scattering on angle-independent structural color in disordered colloidal materials.
TL;DR: In this article, a combination of experiment and theory is used to understand the color peak of colloidal spheres, and it is shown that one significant contribution to the breadth of the main peak is light that is scattered, totally internally reflected from the boundary of the sample, and then scattered again.
