Internal stresses and strains are created in the graphite over time as a consequence of exposure to thermal gradients, structural loads and fast neutron irradiation. However,...

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....

Internal stress is a terminology often used in high temperature creep as a measure of the internal resistance of polycrystalline materials to creep deformation. Changes in...

In this study, in-situ high-temperature loading investigations will be performed to characterise the micromechanics of a high strength alloy 720Li, during stress relaxation in...

The proposed experiment aims to explore in detail these two effects in a thermodynamic range at ~25 MPa over a temperature range of 280° to 600°C, never investigated before,...

Transition metal oxynitrides with perovskite type structures are an emerging class of materials with optical, photocatalytic, dielectric and magnetoresistive properties that may...

We propose to study the structures of Li2NiGe3O8 and Li2ZnGe3O8 using variable temperature high resolution powder neutron diffraction, with the intention of locating the Li...

Hollow nanoparticles (HNP) have been successfully used for encapsulation and controlled release of biochemicals such as drugs, DNA, and dyes. However no in-situ method has been...

Alloy catalysts are commonly employed for selective hydrogenation of organic molecules due to their enhanced selectivity than individual components but their structural and...

Aliphatic polyesters are the most attractive candidates for biodegradable polymers. To improve their physical properties while maintaining biodegradability, incorporating...

We have previously studied proteins with IINS, as well as their building blocks (20 different amino acids). The latter studies of amino acids yielded sharp vibrational peaks...

Welds in safety critical applications are subject to structural integrity assessments where residual stress plays a key part. Dissimilar welds are often used in service without...

A-site-ordered perovskite oxides with formula AA'3B4O12 have a rich variety of physical and chemical properties. Most have Jahn-Teller active Cu2+ or Mn3+ at the square-planar...

Understanding the fundamental aspects of the surface adsorption and self-assembly of biosurfactant and biosurfactant / conventional surfactant mixtures is a major challenge for...

BiCoO3 is a perovskite type material recently prepared by high pressure-high temperature synthesis in Kyoto. It has a distorted acentric perovskite structure with order of high...

Control of crystallisation is essential for many applications ranging from pharaceuticals to packaging and food preservation, yet remains extremely challenging. Recently we have...

Two new A-site ordered perovskite structure oxides, CaCu3Fe4O12 and LaCu3Fe4O12, were recently synthesized under high-pressure and high-temperature conditions in Kyoto. These...

BiNiO3, synthesized at high pressure, has the unusual charge distribution Bi3+0.5Bi5+0.5Ni2+O3 with ordering of Bi3+ and Bi5+ charges on the A sites of a highly distorted...

Neutron reflectivity will be employed to investigate the interaction between dimethylsulphoxide and monomolecular films of phosphatidylcholine. The monolayer will be used as a...

Hydrophobins are secreted fungal proteins and are small lipopeptide biosurfactants. They are strongly surface active and self-assemble at interfaces. Their unique film forming...
