MONODOMAIN SMECTIC LIQUID CRYSTALS OF MEMBRANE LIPID WITH MODEL ION CHANNELS
… annealing ($$80$\mu$ thick x 40mm$\sp2$ area) monodomain defect-free multilayers containing as many as 10$\sp{17}$ uniformly oriented gramicidin channels to be prepared. The alignment of the lipid multilayers was monitored by observing conoscopic interference patterns and orthoscopic images. …

The interplay between order and disorder in cholesteric hydroxypropyl cellulose films
… often assumed that the structure is a perfect monodomain, which would reflect metallic and iridescent colour. However, in macroscopic HPC films, a multitude of domains of various orientations coexist and scatter light multiple times, which results in a more matte appearance. The aim of this …

Competition and Coexistence of Screening Mechanisms in Ferroelectric Thin Films and Superlattices
… be sustained. First-principles calculations of monodomain thin films and superlattices were performed using the virtual crystal approximation to introduce a two-dimensional electron gas through interfacial defects. We observed the screening of the depolarising field by the two-dimensional …

Morphological studies of polymeric systems with liquid crystalline order
… Ndel inversion walls formed in a nematic monodomain during magnetic realignment of a highly elastically anisotropic thermotropic liquid crystal polyether are examined via PLM and AFM.

Nonlinear macroscopic description of liquid crystalline elastomers in external fields
… specific routes of synthesis SCLSCEs feature a monodomain of the liquid crystalline order in the ground state. Their macroscopic coupling of liquid crystalline order and elastic mechanical deformations makes them unique. In particular, we investigate the macroscopic behavior of cholesteric and …

Nanostructured ferroelectric materials
… can be used to form high density arrays of monodomain ferroelectric nanostructures, which is desirable for the miniaturisation of memory devices. This thesis details the use of various types of nanostructuring approaches to fabricate arrays of ferroelectric nanostructures, particularly …

Competing polar and nonpolar distortions and phase transitions in low-dimensional materials
… and a 2DEG. We find that the polydomain and monodomain phases are separated by a region of coexistence in which both phenomena are simultaneously observed. \noindent The final example comes from twistronics, an emerging field in which the properties of layered systems are tuned by introducing …

Design, synthesis and characterization of side chain liquid crystal segmented polyurethanes
… technologies to effect the liquid crystal monodomain ordering required for mechanooptic applications. This thesis describes the design. synthesis and characterization of two series of side chain liquid crystal po I yurethanes. The first series of polyurethanes are made with traditional hard …

A Discrete Monolayer Cardiac Tissue Model for Tissue Preparation Specific Modeling
<p>Engineered monolayers created by using microabrasion and micropatterning methods have provided a simplified in vitro system to study the effects of anisotropy and fiber direction on electrical propagation. Interpreting the behavior in these culture systems has often been performed using …

Cellulose photonics: designing functionality and optical appearance of natural materials
Cellulose is the most abundant biopolymer on Earth as it is found in every plant cell wall; therefore, it represents one of the most promising natural resources for the fabrication of sustainable materials. In plants, cellulose is mainly used for structural integrity, however, some species organise …
