Geometrically Templated Dynamic Wrinkling from Suspended Poly(vinyl alcohol) Soap Films
Yuchong Gao, Yinding Chi, Mohit Patel +4
Wrinkling is commonly observed as mechanical instability when a stiff thin film bound on a compliant thick substrate undergoes in-plane compression exceeding a threshold. Despite s…
Monolithic shape-programmable dielectric liquid crystal elastomer actuators
Zoey S. Davidson, Hamed Shahsavan, Amirreza Aghakhani +5
Macroscale robotic systems have demonstrated great capabilities of high speed, precise, and agile functions. However, the ability of soft robots to perform complex tasks, especiall…
Shaping nanoparticle fingerprints at the interface of cholesteric droplets
Lisa Tran, Hye-Na Kim, Ningwei Li +4
The ordering of nanoparticles into predetermined configurations is of importance to the design of advanced technologies. In this work, we moderate the surface anchoring against the…
Making Faces: Universal Inverse Design of Surfaces with Thin Nematic Elastomer Sheets
Hillel Aharoni, Yu Xia, Xinyue Zhang +2
Programmable shape-shifting materials can take different physical forms to achieve multifunctionality in a dynamic and controllable manner. Although morphing a shape from 2D to 3D…
Elastocapillary driven assembly of particles at free-standing smectic-A films
Mohamed Amine Gharbi, Daniel A. Beller, Nima Sharifi-Mood +4
Colloidal particles at complex fluid interfaces and within films assemble to form ordered structures with high degrees of symmetry via interactions that include capillarity, elasti…
Curvature-driven, One-step Assembly of Reconfigurable Smectic Liquid Crystal "Compound Eye" Lenses
Francesca Serra, Mohamed A. Gharbi, Yimin Luo +5
Confined smectic A liquid crystals (SmA LCs) form topological defects called focal conic domains (FCDs) that focus light as gradient-index lenses. Here, we exploit surface curvatur…
Algorithmic Lattice Kirigami: A Route to Pluripotent Materials
Daniel M. Sussman, Yigil Cho, Toen Castle +4
We use a regular arrangement of kirigami elements to demonstrate an inverse design paradigm for folding a flat surface into complex target configurations. We first present a scheme…
Making the Cut: Lattice Kirigami Rules
Toen Castle, Yigil Cho, Xingting Gong +4
In this paper we explore and develop a simple set of rules that apply to cutting, pasting, and folding honeycomb lattices. We consider origami-like structures that are extinsically…
Focal Conic Flower Textures at Curved Interfaces
Daniel A. Beller, Mohamed A. Gharbi, Apiradee Honglawan +3
Focal conic domains (FCDs) in smectic-A liquid crystals have drawn much attention both for their exquisitely structured internal form and for their ability to direct the assembly o…
Exploiting imperfections: Directed assembly of surface colloids via bulk topological defects
Marcello Cavallaro, Mohamed A. Gharbi, Daniel A. Beller +6
We exploit the long-ranged elastic fields inherent to confined nematic liquid crystals to assemble colloidal particles trapped at the liquid crystal interface into reconfigurable s…
Ring around the colloid
Marcello Cavallaro, Mohamed A. Gharbi, Daniel A. Beller +6
In this work, we show that Janus washers, genus-one colloids with hybrid anchoring conditions, form topologically required defects in nematic liquid crystals. Experiments under cro…
Micro-Bullet Assembly: Interactions of Oriented Dipoles in Confined Nematic Liquid Crystal
Mohamed Amine Gharbi, Marcello Cavallaro, Gaoxiang Wu +4
Microbullet particles, cylinders with one blunt and one spherical end, offer a novel platform to study the effects of anisotropy and curvature on colloidal assembly in complex flui…
