Interaction and self-organization of inclusions in two-dimensional free-standing smectic films

PV Dolganov, P Cluzeau, VK Dolganov - Liquid Crystals Reviews, 2019 - Taylor & Francis
In this article we review interactions and collective behavior of inclusions in free-standing
smectic films with in-plane orientational ordering. The inclusions interact on large distances …

Meniscus and Dislocations in Free-Standing Films of Smectic-A Liquid Crystals

JC Géminard, R Hołyst, P Oswald - Physical review letters, 1997 - APS
A flat, freely suspended film of smectic-A liquid crystal supports a pressure difference, Δp,
across its two free surfaces. The size of its meniscus is about 10 μm, 2 orders of magnitude …

Freely suspended nematic and smectic films and free-standing smectic filaments in the ferroelectric nematic realm

KG Hedlund, V Martinez, X Chen, CS Park… - Physical Chemistry …, 2025 - pubs.rsc.org
We show that stable, freely suspended liquid crystal films can be made from the ferroelectric
nematic (NF) phase and from the recently discovered polar, lamellar SmZA and SmAF …

Topological defect coarsening in quenched smectic- films analyzed using artificial neural networks

RA Chowdhury, AAS Green, CS Park, JE Maclennan… - Physical Review E, 2023 - APS
Mechanically quenching a thin film of smectic-C liquid crystal results in the formation of a
dense array of thousands of topological defects in the director field. The subsequent rapid …

Nanoscopic terraces, mesas, and ridges in freely standing thin films sculpted by supramolecular oscillatory surface forces

Influence of salt on supramolecular oscillatory structural forces and stratification in micellar freestanding films

S Yilixiati, R Rafiq, Y Zhang, V Sharma - ACS nano, 2018 - ACS Publications
Freestanding films of soft matter containing micelles, nanoparticles, polyelectrolyte–
surfactant complexes, bilayers, and smectic liquid crystals exhibit stratification. Stepwise …

Sublimation of isolated toric focal conic domains on micro-patterned surfaces

W Kim, E Vitral, PH Leo, J Viñals, DS Kim, DK Yoon - Soft Matter, 2024 - pubs.rsc.org
Toric focal conic domains (TFCDs) in smectic liquid crystals exhibit distinct topological
characteristics, featuring torus-shaped molecular alignment patterns with rotational …

Coupling between meniscus and smectic-A films: Circular and catenoid profiles, induced stress, and dislocation dynamics

F Picano, R Hołyst, P Oswald - Physical Review E, 2000 - APS
In this paper we discuss the formation and shape of the meniscus between a free-standing
film of a smectic-A phase and a wall (in practice the frame that supports the film). The wall …

Elastocapillary driven assembly of particles at free-standing smectic-A films

MA Gharbi, DA Beller, N Sharifi-Mood, R Gupta… - Langmuir, 2018 - ACS Publications
Colloidal particles at complex fluid interfaces and within films assemble to form ordered
structures with high degrees of symmetry via interactions that include capillarity, elasticity …

Coalescence of islands in freely suspended smectic films

ZH Nguyen, K Harth, AM Goldfain, CS Park… - Physical Review …, 2021 - APS
Smectic liquid crystal films a few molecular layers thick that are freely suspended in air are
used as a model system to study the coalescence of fluids in two dimensions. High-speed …
