The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly has until recently been rarely observed. However, surface multilayer structures...

In a recent EPSRC / Unilever / Oxford CASE project we have used NR to explore and develop optimised delivery mechanism for active benefit agents such as perfumes. In particular...

Ferroelectric BaTiO3 (BT) constitutes a base system for many practical applications ranging from classical capacitors to tunable dielectrics. A dielectric response in BT is...

Oxalyl chloride (mpt. 260 K), forms an ordered phase at low temperature, but a disordered phase between 250 K and the melting point. In previous beamtime we aimed to carry out...

Products such as fabric and hair conditioners are commonly in the form of di-alkyl chain cationic lamellar phase dispersion. The effects of shear on such lamellar phase...

As part of an ongoing effort to understand the underlying physics of MOFs, we propose to study the local structure and dynamics in two quartz-like systems: indium deuterium...

This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages,...

It has always been assumed that CaSnO3 perovskite remains orthorhombic (Pbnm) as a function of temperature up to its melting point, and is rather unremarkable in many ways....

We propose to measure total scattering from Rochelle Salt in order to provide new insights into the re-entrant phase transitions in this material. Rochelle Salt is an old...

Hydrophobins are secreted fungal proteins in the form of small lipopetide biosurfactants. They are strongly surface active and self-assemble at interfaces and in solution. This...

This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled...

The spontaneous formation of multilayer structures at interfaces by surfactant self-assembly is emerging as an important and more common structural signature associated with a...

The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within...

In the context of home and personal care products, studying surfactant and mixed surfactant adsorption ion model solid surfaces, which mimic real surfaces such as fabrics, hair...

Hydrophobins are secreted fungal proteins in the form of small lipopetide biosurfactants. They are strongly surface active and self assemble at interfaces and in solution. This...

Hydrophobins, hfb2, are secreted fungal proteins, which are strongly surface active and possess powerful emulsion and foam stabilising properties. Understanding their...

The formation of multilayer structures at surfaces and interfaces from self-assembly in mixed surfactant and in polymer / surfactant mixtures has been recently reported, and...

Bismuth Ferrite (BiFeO3) is the archetypal multiferroic material and as such has been copiously studied using a wide variety of techniques. Despite this, new structural and...

The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly is an important structural signature associated with a wide range of technological...

This proposal is part of a broad collaboration between Oxford, CCLRC, and Unilever in the study of surfactants and mixed surfactants at interfaces and in solution. This is an...
