We propose to study the kinetics and thermodynamics of polymer:fullerene composite association to provide insight into engineering increased efficiency organic photovoltaics....

For energy storage applications, high energy density is an important material characteristic when searching for new types of suitable materials. LiNi0.5Mn1.5O4 (LNMO) is an...

Ordered double perovskites (also known as elpasolites) have the general formula A2BB’O6 where A is generally a rare earth metal or alkaline earth metal and where B and B’ are...

We have recently carried out an inelastic neutron scattering experiment at LET in order to investigate the excitations in the quantum spin ice Yb2Ti2O7. The single crystal...

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...

The family of hybrid Prussian blue analogues includes many electroactive materials, where organic cations moving within the pores of the cyanide framework cause unusual and...

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...

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 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 Earth¿s climate is strongly influenced by atmospheric aerosols. Organic surfactant films on these aerosols influences their size, optical properties and ability to act as...

Although microemulsions have been widely investigated as potential drug delivery vehicles, relatively little work has been performed establishing the detailed molecular...

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...

We propose to obtain 3 days of beam time on SXD equipped with its new top-loading CCR to analyze CaCrFe3As3 single crystals at different temperatures 10 K, 100 K and 300 K (the...

In this proposal we request 3 days of beam time on HRPD to study the structures (both atomic and magnetic) of a variety of oxychalcogenide phases: La2O2Se2Fe2O, Ce2O2Se2Mn and...

NdMnO3 exhibits A-type antiferromagnetism with TN =73 K. At 15 K, Nd sublattice orders with a (0, -Fy, 0) type ferromagnetic arrangement. Mn spin reorientation from (Ax, Fy, 0)...

Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations...

Water ice displays a remarkably complex phase diagram containing pairs of hydrogen-ordered / disordered phases. Ice XII is a hydrogen-disordered phase and ice XIV is its...

We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible...

Thermal batteries find use in applications such as emergency power systems and ejector seats in aircraft. They operate at elevated temperatures of around 400-500 °C, where the...

There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap and safe cathodes. Li2FeSiO4 shows promising performance as a cathode but...
