Cerium-based Kondo lattice compounds have received considerable attention, owing largely to the variety of exotic ground states that they exhibit (e.g., unconventional...

We have elaborated a new nano-crystallized high capacity Li-Mn-O cathode material, exhibiting record reversible capacities larger than 355 mAh/g and good cyclabilities. RT...

The aim of this experiment is to determine high quality structural models for pyrochlore and zirconolite phases in the Y2Ti2-2xFexNbxO7 and Y2-xCexTi2-xFexO7 solid solutions,...

KxNa1-xNbO3 (KNN)-based solid solutions are promising lead-free piezoelectrics for ceramic actuators. In this system, the long-range order of octahedral rotations and...

This proposal seeks to test a new battery designed to allow in situ neutron diffraction measurements of lithium ion battery electrodes under charge and discharge. We have...

Layered oxides are increasingly attractive as electrode materials in energy technology applications, such as fuel cells, electrolysers and permeation membranes. As the...

We request 6 days of HRPD time in order to study the structures on the tetragonal side of the lead zirconate-titanate (PZT) phase diagram, a region that has so far been rather...

We plan to study the coupling between magnetic properties and local structure of polycrystalline and nanocrystalline chromium. Chromium undergoes a magnetic ordering transition...

Recently, our group has prepared a series of new double perovskite materials (Li1.5La1.5MO6, M=W6+, Te6+) which display interesting electrochemical behaviour for use in Li-ion...

There is a pressing worldwide need for research to develop specific sustainable spent fuel reprocessing technologies suitable for minimizing waste from next generation nuclear...

To develop the next generation of high performance Li-ion rechargeable batteries we need to find new positive electrode materials with a greater capacity to store charge. It is...

Single-Molecular Magnets (SMMs) provide access to the mesoscopic world. They possess slow magnetization relaxation due to an energy barrier induced by axial magnetic anisotropy,...

The migration of cations with a charge greater than 1 has received very little attention historically, perhaps due to no commercially driven demand for the research as well as...

To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently...

Oxide ion conductors are researched as potential electrolytes in solid oxide fuel cells (SOFCs). Yttria-stabilized zirconia is currently the most commonly used electrolyte in...

Solid-state electrolyte materials are crucial for applications involving electrochemical conversion and storage, as these devices become increasingly important in the transition...

The width of a peak in a pair distribution function (PDF) provides a measure of the variation in the distance between a pair of atoms. This results from a combination of thermal...

Bismuth(III) containing oxides display numerous interesting properties, such as ionic conductivity, ferroelectricity, nonlinear optical properties, catalytic activity and...

Barium hydride is a of interest due to its high hydride ion conductivity, which would make it suitable as an electrolyte materials in a variety of electrochemical devices and...

Atomistic characterisation of phase transitions in organic materials is important because of the role played by polymorphism in pharmaceuticals and agochemicals. Conventional...
