Journal ArticleDOI
Template-directed colloidal crystallization
TL;DR: In this article, the slow sedimentation of colloidal particles onto a patterned substrate (or template) can direct the crystallization of bulk colloidal crystals, and so permit tailoring of the lattice structure, orientation and size of the resulting crystals.
Journal ArticleDOI
Electrochemically grown photonic crystals
Paul V. Braun,Pierre Wiltzius +1 more
TL;DR: In this paper, the authors explored the use of colloidal crystallization as a fabrication method for photonic crystals and found that the photonic behavior such as photonic band-gaps is expected only for very high index of refraction contrast systems, which can be achieved through electrodeposition of semiconductors, polymers, or metals in the interstitial space of self-assembled colloids.
Journal ArticleDOI
Patterned colloidal deposition controlled by electrostatic and capillary forces.
TL;DR: This approach makes it possible to fabricate complex, high-resolution two-dimensional arrays of colloidal particles, and the driving forces of the process, i.e. screened electrostatic and lateral capillary interactions, are discussed.
Journal ArticleDOI
Direct‐Write Assembly of 3D Hydrogel Scaffolds for Guided Cell Growth
Robert Barry,Robert F. Shepherd,Jennifer N. Hanson,Ralph G. Nuzzo,Pierre Wiltzius,Jennifer A. Lewis +5 more
TL;DR: In this article, a direct-write assembly of an acrylamide-based ink was proposed to obtain 3D microperiodic hydrogel scaffolds with micrometer-sized features.
Journal ArticleDOI
Monolithically integrated, flexible display of polymer-dispersed liquid crystal driven by rubber-stamped organic thin-film transistors
TL;DR: In this article, the authors describe the monolithic integration of rubber-stamped thin-film organic transistors with polymer-dispersed liquid crystals (PDLCs) to create a multipixel, flexible display with plastic substrates.
