The BIMEVOXes are an important family of fast oxide ion conducting solids that exhibit very high conductivities at low and intermediate temperatures. A study of local ordering...

Research within the field of functional oxides has always been very active. In recent years systems showing a coupling between ferroelectricity and magnetism have become one of...

This proposal requests 6 days on Tosca to investigate the nature of local structure and proton sites in the proton conducting brownmillerite system Ba2In1.85M0.15O6H2 (M = In,...

This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages,...

Ferroelectric BaTiO3 (BT) constitutes a base system for many practical applications ranging from classical capacitors to tunable dielectrics. A dielectric response in BT is...

The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong...

This proposal requests 4 days on Tosca to investigate the local structure and vibrational properties of phospors for solid state white lighting. The key objective is to...

This proposal is a low-cost/high-gain first step in an ambitious project: namely, to develop a combined neutron scattering and electronic structure calculation approach as a...

This proposal aims to study local structure and dynamics in two metal-organic frameworks (MOFs): namely, zinc imidazolate and cobalt imidazolate. Imidazole (IM) is a small, flat...

We will carry out a definitive local structure investigation of the ferroelectric transition in [ND4][Zn(DCOO)3]. This compound is seen as the canonical example of a...

We propose to use two days of beamtime on POLARIS to carry out the first analysis of the Pair Distribution Function of lithium-conducting garnets. These materials show...

We propose to study the local structure in two series of promising thermoelectric materials: Ti1-xZrxNiSn and TiNi1+ySn. Diffraction experiments on Ti1-xZrxNiSn reveal multiple...

Ortho-terphenyl is a paradigmatic example of a molecular glass-former; yet the structure of its glass has never been fully described. We have recently demonstrated that, by...

The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong...

Derivatives of the perovskite NaNbO3 are currently being studied as benign replacements for piezoelectric Pb(Zr,Ti)O3. In order to understand the structure-composition-property...

This proposal requests 3 days on Maps to investigate the nature of local structure and proton sites in the proton conducting brownmillerite system Ba2In1.85M0.15O6H2 (M = In,...

We propose to study by total neutron scattering the structures of some complex oxide materials prepared by new hydrothermal routes in order to construct structural models...

This proposal is focused on developing an understanding of how surfaces affect the local structure of synthetic polymers. There is considerable evidence for a strong variation...

Lithium iron phosphate is a commonly used cathode material in Li-ion batteries. The material exhibits a two phase system on lithiation and delithiation with narrow solid...

The development of new interstitial oxide conductors with less restrictive structural constraintsrequires understanding of the mechanisms allowing both incorporation and...
