Structural study of lipid bicontinuous cubic phases for cellular delivery
Lipid bicontinuous cubic phase is fundamentally interesting phase. Initially it is considered as an intermediate structure between lamellar and hexagonal phases due to its small phase space and complicated structure. With the development of structure characterization technologies, especially X-ray …

Design, Synthesis and Self-assembly of Amphiphilic Cyclodextrin-Based Materials for Enhanced Ion Conduction and Drug Encapsulation
… have shown unprecedented ability to form bicontinuous cubic mesophases. Chapter 3 builds upon the findings of the previous chapter by enhancing the synthetic efficiency and investigating the ‘open’ crown-ether concept, achieved by incorporating linear OEG chains onto a benzene ring in …

A Mesoscale Dynamics study of the phases in surfactant-water ternary systems
… high-surface curvature phases, such as the bicontinuous cubic and mesh phases, in favour of the lamellar phase. However, the addition of anaesthetics and short-chained alcohols, which are small amphiphilic molecules, promote surface curvature, and there is an optimum chain length for maximum …

Computer simulation of rod-sphere mixtures.
… microphase separated structures including bicontinuous, cubic, and micelle-like arrangement have been observed in bulk. Thirdly, the four types of mixtures previously studied in bulk are subjected to a static magnetic field. A variety of novel phases are observed for the cases of positive …

The mesophase structure of surfactants
… intermediate phases in preference to the bicontinuous cubic phases usually encountered between hexagonal and lamellar phases in shorter chain homologues. A nematic phase has also been observed in the water penetration scan. The intermediate phase is extensive, ranging from 32 to 60% …

Computer simulations of tapered particles
… investigated further and found to be a type of bicontinuous cubic phase, specifically the Ia3d or gyroid (G) as it is also known -a phase never before obtained from this type of simulation. Characterisation of the I-G transition was undertaken, which indicated that the gyroid freely …

NMR Applications in Soft Materials Science: Correlation of Structure, Dynamics, and Transport
… materials undergo a transition from columnar to bicontinuous cubic phases with a simple increase in humidity, while the amorphous domain boundaries consist of individual wedge molecules with a significant fraction (~ 10%) of total wedge molecules. Multiple-component diffusion of both wedges and …

Self-assembly of nanostructured amphiphiles onto surfaces: Design principles for substrate mediated biomedical applications
… diverse symmetry. The lipid films displayed 3D bicontinuous cubic, 2D inverted hexagonal, and 1D lamellar structures yielding X-ray diffraction patterns resembling that of single crystals. The genetic materials (small interfering RNA or siRNA) were successfully incorporated into the films. …
