Thermal expansion studies of metallic glasses showing magnetocaloric effect
The main aim of our proposal is investigation of thermally induced volume changes occurring in short range order of amorphous pseudo-binary Fe(Mn)-B alloys in the vicinity of... -
Hydrogen from ammonia using lithium imide metal nitride composites
Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
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... -
Molecular motions in novel water-soluble organometallic gels
The aim of this proposal is to study the internal dynamics of a novel organometallic polymers based on two metal-containing moieties -Ru, Au- bridged through a tridentate... -
Diffuse scattering in the paraelectric phase of titanite
Titanite consists of TiO6 octahedra arranged in chains. These are linked by SiO4 tetrahedra. At room temperature, Ti is slightly off-center resulting in an alternation of short... -
In-Situ Studies of Electrochemically Enhanced Performance in Perovskite Elect...
Recent studies in our laboratory have shown that a range of A-site deficient perovskite oxides, with carefully tuned chemical compositions, exhibit excellent properties when... -
Define the crystal structures of lead-free ferroelectric, candidate multiferr...
We have a range of new structures in the lead-free ferroelectric, candidate multiferroic and SOFC cathode areas. The HRPD data will be used to define these new crystal... -
Monomer dynamics in polymer nanocomposites
We have recently shown that the addition of single walled carbon nanotubes produces a minimum in the diffusion coefficient with increasing nanoparticle concentration. Initially,... -
Investigation of Atomic Disorder Effects in Ti1-xZrxNiSn
We propose to investigate the arrangement of Ti, Zr, Ni and Sn over the 4 available atomic sites in the half-Heusler structure for the title series. This will help rationalise... -
Apatite-type Oxides for Energy Applications: Role of Lattice Dynamics
Lanthanum-containing germanate apatites are materials with potential applications as electrolytes in solid oxide fuel cells. The conductivity of these materials is known to... -
Average structures of new functional oxides - HPRD
The proposal addresses the average structures of new lead-free ferroelectrics, low-temperature ionic conductors and mixed conductors which are candidate solid oxide fuel cell... -
Oxygen Dynamics in Y2O3 doped Bi2O3: (Bi0.8Y0.2)2O3 and (Bi0.6Y0.4)2O3
The high ionic conducting delta-phase of Bi2O3 can be stabilized at ambient temperature in a range of compositions, viz., (Bi1-xYx)2O3 (x=0.1 -0.5). We would measure inelastic... -
Local magnetic order and the paramagnetic-parmagnetic transition in MnO
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... -
Monomer dynamics in polymer nanocomposites
We have recently shown that the addition of single walled carbon nanotubes produces a minimum in the diffusion coefficient with increasing nanoparticle concentration. Initially,... -
Order-disorder transitions in ternary unfilled skutterudites
The aim of this proposal is to study the thermal evolution of the structure of two ternary ordered skutterudites, CoGe1.5Q1.5 (Q = S, Te). At room temperature, ordering of the... -
Electronically-driven structural transition in Ti-doped Ca3Ru2O7
The purpose of the experiment is to determine the effect of titanium doping on the structural and magnetic transitions of Ca3Ru2O7. The pure material undergoes a Néel transition... -
Variable temperature study of the structure of the new bimetallic, mixed anio...
We propose 1 day of beam-time on GEM to probe changes in the crystal structure of the new fast Li+ conducting mixed-cation, mixed-anion phase, Li0.5Na0.5(BD4)0.83I0.17 as a... -
The structures of PZT in its ¿rhombohedral¿ phases and their dependence on th...
In the piezoelectric ceramic material PbZrxTi1-xO3 (PZT) there is controversy about the structure of PZT at the Zr-rich end. This region has always been considered to be of... -
Ammonia synthesis using lithium hydride-metal nitride composites: an in situ ...
The development of more active catalysts for the production of ammonia will have a worldwide impact on the energy cost of producing fertiliser. Composites of lithium hydride and...
