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...

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)...

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...

Metal-organic perovskites offer many of the advantages of their ceramic analogues, with a range of exploitable functionality including ferroelectricity. Understanding the...

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...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

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

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...

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...

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

Cu2ZnSnS4 (CZTS) is a solar cell material of great interest. However the material when fabricated, although of high symmetry, contains substantial defect concentration and a...

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...

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...

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...

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...

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