Self-organized dynamics and the transition to turbulence of confined active nematics
Achini Opathalage,Michael Norton,Michael Juniper,Blake Langeslay,S. Ali Aghvami,Seth Fraden,Zvonimir Dogic,Zvonimir Dogic +7 more
TL;DR: It is shown that confining a model experimental active nematic converts bulk chaotic motion into coherent circulatory flows, suggesting the possibility of exploiting geometric design to encode the spatiotemporal dynamics of topological defects, thereby endowing synthetic materials with the self-organized capabilities heretofore mainly found in living organisms.

X-ray transparent Microfluidics for Protein Crystallization and Biomineralization
Achini Opathalage
- 01 Jan 2016
TL;DR: Achini et al. as discussed by the authors developed an emulsion-based serial crystallographic technology in nanolitre-sized droplets of protein solution encapsulated in to nucleate one crystal per drop.

Low-Z polymer sample supports for fixed-target serial femtosecond X-ray crystallography
Geoffrey K. Feld,Geoffrey K. Feld,Michael Heymann,Michael Heymann,W. Henry Benner,T. Pardini,Ching-Ju Tsai,Sébastien Boutet,Matthew A. Coleman,Mark S. Hunter,Xiao-Dan Li,Marc Messerschmidt,Achini Opathalage,Bill Pedrini,Garth J. Williams,Garth J. Williams,Bryan A. Krantz,Seth Fraden,Stefan P. Hau-Riege,James E. Evans,Brent W. Segelke,Matthias Frank +21 more
TL;DR: The fixed-target approach to sample delivery involves depositing samples on a thin-film support and subsequent serial introduction via a translating stage as discussed by the authors, where the sample of interest must be serially replaced after each destructive pulse.
Insensitivity of active nematic liquid crystal dynamics to topological constraints
Michael Norton,Arvind Baskaran,Achini Opathalage,Blake Langeslay,Seth Fraden,Aparna Baskaran,Michael F. Hagan +6 more
TL;DR: It is found that anchoring conditions are screened by the active flow, preserving system behavior across different topological constraints, identifying a fundamental difference between active and equilibrium materials.
Rapid prototyping of cyclic olefin copolymer (COC) microfluidic devices
S. Ali Aghvami,Achini Opathalage,Zhengpu Zhang,Markus Ludwig,Michael Heymann,Michael Heymann,Michael Norton,Niya Wilkins,Seth Fraden +8 more
TL;DR: In this paper, a low-cost, high-yield rapid fabrication method for casting COC microfluidic chips that is appropriate for academic labs and small companies is introduced.
