Significance Three-dimensional shaping of thin sheets and membranes is a ubiquitous feature of materials science and underlies diverse biological processes, ranging from large-scale morphogenesis to molecular drug delivery. It is also a familiar everyday phenomenon, as illustrated by the formation of soap bubbles. We demonstrate how flat disk–shaped colloidal membranes transform into saddle-like surfaces. As membranes coalesce, the saddle-shaped surfaces form catenoid-like structures and other…

The thermodynamic origins of chiral twist in monolayer assemblies of rod-like colloids.

The propagation of chirality across scales is a common but poorly understood phenomenon in soft matter. Here, using computer simulations, we study twisted monolayer assemblies formed by both chiral

Morpho -- A programmable environment for shape optimization and shapeshifting problems

An emerging theme across many domains of science and engineering is materials that change shape, often dramatically. Determining their structure involves solving a shape optimization problem where a

Configurations of fluid membranes and vesicles

Abstract Vesicles consisting of a bilayer membrane of amphiphilic lipid molecules are remarkably flexible surfaces that show an amazing variety of shapes of different symmetry and topology. Owing to

Achiral symmetry breaking and positive Gaussian modulus lead to scalloped colloidal membranes

The results provide insight into how the interplay between membrane elasticity, geometrical frustration, and achiral symmetry breaking can be used to fold colloidal membranes into 3D shapes.

Self-assembly of 2D membranes from mixtures of hard rods and depleting polymers().

This work demonstrates that collective molecular protrusion fluctuations alone are sufficient to stabilize membranes composed of homogenous rods with simple excluded volume interactions.

Imprintable membranes from incomplete chiral coalescence

This report studies coalescence pathways of circularly shaped two-dimensional colloidal membranes, which are one rod-length-thick liquid-like monolayers of aligned rods, and describes two pathways that do not proceed to completion but instead produce partially joined membranes connected by line defects.

Chiral molecules on curved colloidal membranes.

This work presents a covariant theory for the tilt pattern on minimal surfaces, like helicoids and catenoids, which have been generated in the laboratory only recently and predicts several non-uniform tilt patterns, some of which are consistent with experimental observations and some, which are yet to be discovered.

Entropy driven self-assembly of nonamphiphilic colloidal membranes

An entropic mechanism that explains the stability of colloidal membranes and offers a general design principle for the self-assembly of 2D nanostructured materials from rod-like molecules is proposed.

Observation of Stable Shapes and Conformal Diffusion in Genus 2 Vesicles

The observed equilibrium shapes of phospholipid vesicles of topological genus 2 (shapes with two holes) are found to be in agreement with theoretical predictions on the basis of a minimization of the

A geometric theory on the elasticity of bio-membranes

A geometric scheme is proposed to deal with the variational problems on surfaces embedded in three-dimensional Euclidean space by using exterior differential forms.

Cubic membranes: a legend beyond the Flatland* of cell membrane organization

It is shown that the “organized smooth endoplasmic reticulum” (OSER) is actually the two-dimensional representation of two subtypes of cubic membrane morphology, and may provide a valuable tool to study cubic membrane formation and function at the molecular level.

Structure, dynamics and phase behavior of short rod inclusions dissolved in a colloidal membrane.

It is demonstrated that colloidal membranes serve as a versatile platform for assembly of soft materials, while simultaneously providing new insight into universal membrane-mediated interactions.
