This proposal follows from a short previous test experiment (RB 920345) aimed at understanding the nature of local structure distortions in YBa2Cu3O6.9 and their possible role...

Graphene is a very promising material and appears particularly suitable in order to develop efficient hydrogen storage systems, especially if it is ¿decorated¿ with proper metal...

Ionic conductivity is a property where a material is able to conduct electricity through the movement of ions. Oxide ion conductors can be used in solid oxide fuel cells, which...

Bismuth germanate glasses are technologically important for a number of reasons, including fibre-optical and laser applications, non-linear optical glasses, IR transmitting...

We propose to use a pulsed magnet system tried and tested at several neutron and synchrotron facilities in conjunction with the new high flux diffractometer WISH to perform the...

Complex oxides within the family CeNbO4 have been shown by single crystal x-ray studies to have superstructured average structures, but little detail has been obtained about the...

A very important property of O/W microemulsions is the exchange dynamics of the oil molecules. So far little is know about that, despite the fact that its control is crucial for...

The hydroxides Me(OH)2 of the bivalent transition metals Co, Cu, Fe, Mn, Ni, Cd and Zn play critical roles as sorbents, catalysts or reductants in many environmental and...

The structure of the phosphate materials Na_{1+x}Ge_{2-x}Al_x(PO_4)_3 with x = 0, 0.4 and 0.8 will be investigated using high real-space resolution neutron diffraction. In the...

The research on new anode materials for solid oxide fuel cell is extremely important for its potential to overcome the drawbacks of current state of the art anodes. In this...

Relaxor ferroelectrics are a class of locally disordered crystals possessing peculiar structure and electrical properties. The solid solution of a relaxor perovskite and PbTiO3...

The aim of this project is to understand the influence of an applied electric potential on the structure of a porous non-covalent network-based electrode in the presence of an...

We propose to study the phase diagram of a lead-free piezoelectric material consisting of a tricritical triple point where anomalous enhancement of the physical properties have...

Molybdenum based-oxides have recently attracted interest for use as electrolyte and electrode materials in Solid Oxide Fuel Cells. This proposal requests 5 days of beamtime on...

We have developed a new and benign method for the production of cellulose based aerogels, highly porous materials with applications in insulation, drug delivery, gas storage,...

We have synthesized and characterized a new member, namely Fe2V2O7 in the family of 3d transition metal pyrovanadate M2V2O7 (M =Mn, Fe, Co, Ni, Cu). M2V2O7 exist with a great...

It has recently been discovered than the rutile phase of zinc fluoride shows negative thermal expansion along all three crystallographic axes. What is highly unusual about this...

Alkali borogermanate glasses are topologically complex, in that [BOn] (n = 3, 4)and [GeOn] (n = 4, 5, 6) polyhedra may all coexist. Equilibrium between these structural units...
