Polymers, end-functionalised with carboxylic acid (COOH) groups do not normally segregate to film surfaces due to the high surface energy of these functionalities. However, we...

Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al...

Off-specular neutron reflection is potentially a powerful technique for studying the lateral organisation of phospholipid bilayers. However, this has not yet been demonstrated....

We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing...

We have prepared a new family of rare-earth carbonates, R4(CO3)6(H2O)2en (R=Dy-Lu). With the exception of R=Er, all materials exhibit a steadily decreasing meff below 70K. The...

We aim to continue our investigation of the high temperature magnetic interactions in LaCoO3. Our previous experiment has confirmed magnetic susceptibility data, with a change...

When nanoparticles enter a biosytem they rapidly acquire a protein corona. The nature of the outer part of this corona will determine the response of the biosystem to the...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...

Oxide ceramics based on ceria, CeO2, have been the subject of considerable research for the role of solid electrolyte within solid oxide fuel cells (SOFCs), since their ionic...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

Natural antimicrobials are of great interest, since they are antibiotics that act on the biological membrane, and it is believed that this makes it far more difficult for...

For many Heusler compounds a spin polarisation close to 100% was predicted by band structure calculations. Thus if those materials are incorporated in magnetic tunnel junctions,...

Multiferroic materials are rare and exceptional: they are ferroelectric and ferromagnetic in the same phase and these two properties can couple. Recently, materials with complex...

This proposal seeks to identify and characterise the adsorption of primary linear amides that adsorb to the surface from the bulk of a polymer melt. These layers are...

The asphaltene fraction of crude oil is defined by its solubility parameters (insoluble in n-heptanebut soluble in toluene). Changes in conditions (temperature, pressure,...

The 'non-magnetic' ground state of a Kondo ion is generally believed to consist of the localised spin surrounded by a compensating cloud of conduction electrons coupled...

This proposal aims to investigate the evolution of the structures of layered oxysulfide materials which show promise as lithium ion battery electrodes. The lithiation of...

We are investigating the ultra-rapid synthesis of transition metal carbides using microwave (MW) irradiation. Currently we are establishing an understanding of these reactions...

NMR has become an extremely sophisticated experimental technique because of the use of pulse sequences which allow the control and manipulation of a nuclear spin system or...

For the first time, the research team aim to use INS to characterise a series of candidate methane reforming catalysts. Recent studies have shown that modification of...
