The hepta-nuclear Fe(III) title compound Fe7 exhibits a unique antiferromagnetic exchange topology reminiscent of a three-bladed propeller, giving rise to spin frustration, also...

The performance of polymer electrolyte fuel cells (PEMFC) is strongly dependent on the diffusion rate of hydrogen and the electron mobility, which in turn is strongly influenced...

Understanding high-temperature superconductivity is a major aim of condensed-matter science, which is of fundamental importance and may ultimately allow the design of materials...

The structure and dynamics of water molecules in the presence of non-trivial confinement in porous systems has always created a lot of interest, both from an experimental and...

Sr0.75Y0.25CoO2.62 is a promising cathode material for solid oxide fuel cells. It shows metallic behaviour above 600K and molecular dynamics simulations have concluded that...

We propose to conduct inelastic neutron scattering measurements on a deuterated polycrystalline sample of the {Fe9} molecule [(Fe9-3-O)4 (O3PPh)3(O2CCMe3)13] to...

Motivated by the observation of incommensure magnetic order in Ba(Fe1-xCox)2As2, we have recently grown BaFe2-xNixAs2 crystals with systematic electron doping level especially...

We aim to determine the magnetic excitation spectrum in single-crystals of the parent LaFeAsO compound and thereby address some basic issues concerning the nature of the...

Fluidised Catalytic Cracking (FCC) units are one of the major conversion units in modern petrochemical refineries. ZSM-5 additives are used in FCC units to convert gasoline...

The experiment is aimed to unravel the diffusion mechanism of hydrogen in Callovo-Oxfordian clays, which are candidates to be used as backfill material in long term geological...

Oxides containing heavy transition-metal ions with four d electrons (d^4) surrounded by an octahedron of oxygen ions have recently been predicted to display a novel type of...

Flexible functional materials are important candidates of current research, because of their potential applications in plastic electronics. Organic ferroelectrics and...

We propose to use OSIRIS to determine the magnetic structures of a series of cobalt oxysulfides containing Co in square planar coordination. Several compositions...

In this proposal, we would like to propose to perform neutron diffraction experiments on the powder samples of the frustrated antiferromagnets AFeO2 (A=Cu and Ag) using WISH. In...

The subjects of this proposal, Ho2+xTi2-xO7-x/2, are brand new materials1 related to Ho2Ti2O7, a spin ice2,3. They have the remarkable property of remaining disordered at very...

The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...

The discovery of slow relaxation of the magnetization and quantum effects in the single-molecule magnet (SMM) Mn12-ac in 1993 has inspired both physicist and chemist alike. A...

We request 4 days on HRPD with the IGAn apparatus to follow the structural changes of Me-ND4 11BD4 as a function of temperature. The high resolution of HRPD will allow us to...

Reflectin, so named because of its high refractive index, is a protein expressed exclusively in cephalopods and forms reflectors responsible for dynamic iridescence and...

Most of the one dimensional spin chain compounds are antiferromagnetic with a rich magnetic phase diagram due to the magnetic frustration. We have synthesized Ba3CrS5 and...
