Investigation of magnetic orderings in multiferroic PbFe12O19
We propose to perform neutron diffraction experiments on a powder sample of a multiferroic hexaferrite PbFe12O19. A recent paper has reported room temperature multiferroic... -
Reentrant Structural Transitions and Collapse of Charge and Orbital Orders in...
A-site ordered quadruple perovskites, AA3B4O12, show many interesting physical and chemical properties, for example, inter-site charge transfer and disproportionation, giant... -
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... -
Characterisation of the magnetic properties of SnxFe4xN
Gamma'-Fe4N exhibits fascinating magnetic properties. It adopts a simple perovskite-like structure (space group Pm-3m) with iron atoms occupying the corners (Wyckoff position... -
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... -
In-situ studies of amides with ammonia
The aim of this proposal is to determine that materials that are present in the ammoniation of amides. -
Hydrogen production from ammonia using lithium imide: an isotope study
We have recently discovered that light metal amides and imides are excellent cattalysts for the decomposition of ammonia. We request 3 days on POLARIS to perform in situ neutron... -
Understanding the decomposition of ammonia by lithium-calcium imide
Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data... -
Towards the development of carbonitrides as novel two-stage regenerable reage...
We are examining a number of cobalt-molybdenum carbonitrides as possible catalysts for reactions that produce nitrogen-containing organic molecules. There is good evidence that... -
