Variable temperature structural study of oxides with low thermal conductivity
The aim of the experiment is to investigate the temperature evolution of the crystal structure for two transition metal oxides with low lattice thermal conductivities. This will... -
Structure Sequence in Ca(1-x)Nd2x/3TiO3 Ceramics
Microwave dielectric ceramics are used in communications devices. Such materials need high relative permittivity, high dielectric quality factor and be temperature stable.... -
Structure of Molecular Hydrogen in High Charge Pillared Clays
In this proposal we aim to study low temperature structure of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual motivations for this... -
Study of the interfacial self-assembly of peptide/polymer membranes by neutro...
The interfacial self-assembly between large (polymer) and small (peptide) molecules of opposite charge results in the formation of highly organized membranes. Furhter... -
Sensing SO2 in Robust Porous MOF Materials via Simultaneous Microwave Dielect...
We seek to develop new MOFs for sensing and removal of toxic gases (e.g., SO2) and request 4 days on POLARIS to study the structural binding details and dielectric data... -
The effect of γ′ particle size on the γ/γ′ load tr...
The aim of this experiment is to measure the load transfer between the matrix and the precipitates in an advanced nickel¿base superalloy as a function of particle size... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
High temperature neutron powder diffraction studies of polymorphism in Li3+xV...
Novel oxide ceramics with high values of lithium-ion conductivity at ambient temperatures are required as an essential part of the development of new lithium battery... -
Ferroelastic transitions in quantum critical tetragonal tungsten bronzes
Tetragonal tungsten bronzes have three types of channels for ions with the smallest unusually occupied with Li in potassium lithium tantalate (KLT). This creates complexity... -
Does The Crystal Structure of Leucite Evolve with Temperature to the Proposed...
The concept of an aristotype, or equivalently, the basic structure, that represents the highest symmetry crystal structure that can be attained, either experimentally, or... -
Understanding Deep Earth Mineralogy: A High P/T study of CaSiO3 Perovskite
CaSiO3 perovskite is the third most abundant mineral in the Earth's lower mantle; it also occurs as a major phase at lower pressures and temperatures in subduction zones, where,... -
Variable temperature structural study of Ca1-xSrxMnO3-d perovskites for use i...
CaMnO3-based perovskite oxides show promise as solid oxygen carriers for use in chemical looping. Partial substitution with small amounts of Sr increases both the capacity and... -
Complex ordering in a new polar A-site deficient perovskite
Recent theoretical work has identified that oxygen octahedral rotations (OORs) in layered perovskites such as Ruddlesden-Popper (RP) phases can generate noncentrosymmetry...
