Imprintable membranes from incomplete chiral coalescence

MJ Zakhary, T Gibaud, C Nadir Kaplan, E Barry… - Nature …, 2014 - nature.com
Coalescence is an essential phenomenon that governs the equilibrium behaviour in a
variety of systems from intercellular transport to planetary formation. In this report, we study …

Chiral edge fluctuations of colloidal membranes

LL Jia, MJ Zakhary, Z Dogic, RA Pelcovits, TR Powers - Physical Review E, 2017 - APS
We study edge fluctuations of a flat colloidal membrane comprised of a monolayer of aligned
filamentous viruses. Experiments reveal that a peak in the spectrum of the in-plane edge …

Theory of microphase separation in bidisperse chiral membranes

R Sakhardande, S Stanojeviea, A Baskaran… - Physical Review E, 2017 - APS
We present a Ginzburg-Landau theory of microphase separation in a bidisperse chiral
membrane consisting of rods of opposite handedness. This model system undergoes a …

Capillary nematisation of colloidal rods in confinement

KE Klop, RPA Dullens, MP Lettinga, SA Egorov… - Molecular …, 2018 - Taylor & Francis
We confine a colloidal liquid crystal between parallel plates separated down to several times
the rod length. By connecting the system to a reservoir we effectively create a grand …

Force-induced formation of twisted chiral ribbons

A Balchunas, LL Jia, MJ Zakhary, J Robaszewski… - Physical Review Letters, 2020 - APS
We demonstrate that an achiral stretching force transforms disk-shaped colloidal
membranes composed of chiral rods into twisted ribbons with handedness opposite the …

Shape optimization of self-avoiding curves

SW Walker - Journal of Computational Physics, 2016 - Elsevier
This paper presents a softened notion of proximity (or self-avoidance) for curves. We then
derive a sensitivity result, based on shape differential calculus, for the proximity. This is …

Rafts in colloidal membranes: the role of rod chirality and length in monolayer phase separation

J Miller - 2019 - search.proquest.com
Membrane-mediated particle interactions depend both on the properties of the particles
themselves as well as the membrane environment in which they are suspended …

Self assembly of cyclic polygon shaped fluid colloidal membranes through pinning

L Saikia, P Sharma - Soft Matter, 2018 - pubs.rsc.org
2D fluid monolayer membranes of rod-like viruses spontaneously form in a mixture of rods
and polymers through depletion attraction. The rods are uniformly oriented within the bulk …

[BOOK][B] Quantifying the Bending Modulus and Gaussian Curvature Modulus of Self-Assembled Colloidal Membranes

AJ Balchunas - 2018 - search.proquest.com
A challenge in studying membrane materials is that they almost always present themselves
as three-dimensional vesicles due to the length of the constituent particles. However, prior to …

Optimal control of surface shape

H Antil, SW Walker - arxiv preprint arxiv:1407.4297, 2014 - arxiv.org
Controlling the shapes of surfaces provides a novel way to direct self-assembly of colloidal
particles on those surfaces and may be useful for material design. This motivates the …
