A Single Bicontinuous Cubic Phase Induced by Fusion Peptides

Structural transitions of the mono-olein bicontinuous cubic phase induced by inclusion of protein lysozyme solutions.

Inclusion of protein lysozyme molecules in the lipidic mono-olein cubic phase induces a transition from a Pn3m structure to an Im3m one. The small-angle x-ray scattering method with high-intensity synchrotron radiation enabled us to follow closely the transition depending on the conditions of lysozyme solutions. We show that concentrated lysozyme solutions induced the appearance of the Im3m str...

X-ray scattering by bicontinuous cubic phases

-Ia3d bicontinuous cubic phases are interpreted as constituted of a fluid film of constant thickness supponed by the gyroid minimal surface. We first compute the gyroid structure factor. Then we decorate the surface by the film. We compute the diffracted intensities and compare to X-ray intensities measured in some lipid

Orientation of the Inverse Bicontinuous Cubic Phase Induced by Combination of Oscillatory Shears with Different Strain Amplitudes

Electrostatic swelling of bicontinuous cubic lipid phases.

Lipid bicontinuous cubic phases have attracted enormous interest as bio-compatible scaffolds for use in a wide range of applications including membrane protein crystallisation, drug delivery and biosensing. One of the major bottlenecks that has hindered exploitation of these structures is an inability to create targeted highly swollen bicontinuous cubic structures with large and tunable pore si...

PHYSICAL MATHEMATICS SEMINAR Liquid Infused Surfaces and Phase Separation on Bicontinuous Cubic Membranes

This seminar consists of two parts. First, I will talk about a novel class of functional surfaces, termed liquid infused surfaces, which have been shown to exhibit a wide-range of advantageous surface properties, including self-cleaning, drag reduction, anti-icing and anti-fouling. Unlike standard wetting problems, our theory shows that the contact angle of a droplet on liquid infused surfaces ...
