In situ NPD investigation of double perovskite manganites in wet hydrogen atm...
The aim of the experiment is to investigate by means of in situ NPD the structural behavior of two new Mn-rich double perovskites compounds, NdBaCo1.5Mn0.5O5+d and NdBaMn2O5+d... -
Structure-conductivity relationship in La2-xBaxNiO4+d
Unusual total conductivity behaviour at high Ba contents may be attributed to a change in conduction mechanism at high tempertaures, structure change or phase... -
Defect structure in W/Ln and Ta/Ln di-substituted bismuth oxide based solid e...
The stability regime of the oxide ion conductor delta-Bi2O3 is limited to a narrow temperature range just below its melting point. Substitution of Bi3+ by a variety of isovalent... -
In situ studies of mixed-phase oxygen transport membranes
The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen... -
Determination of the accurate crystal structure of Na2ZrO3 and its conversion...
The aim of the proposal is to study the crystal structure of Na2ZrO3, which is one of the key solid-state materials for CO2 capture. Laboratory experiments have established a... -
Order-Disorder Transitions in Layered Tellurides
We have prepared a new series of layered tellurides Cr2-xInxGe2Te6, containing 2D ordered arrays of (Cr,In) cations and (Ge-Ge) pairs. Recent neutron measurements reveal indium... -
In-situ QENS studies of the nitridation of Calcium Hydride
The proposed experiment will study how material properties change as a function nitridation (eg. the incorporation of nitrogen gas into the material). In previous study at RAL,... -
