Methylammonium lead iodide (MAPI) is one the most promising materials for photovoltaics. Notwithstanding the above, access to its phase diagram and the underlying structural...

Organic-inorganic lead halide perovskite compounds are shown to be very promising candidates for low cost, solution-processable, highly efficient (>22%) solar cells with a...

In nucleophilic fluorination reactions it is extremely difficult to tune the reactivity of the fluoride anion in organic solution to give the desired product. Building on our...

We will use the high resolution of HRPD and the excellent long d-spacing data available on OSIRIS to investigate the phase transitions in Sr1-xNaxFe2As2 which are associated...

The dipeptides are a class of organic molecules that form hexagonal crystalline structures (space group P61) with one-dimensional chiral channels of tunable pore diameters in...

We have synthesised the series of lanthanide complexes Ln(trensal-thiophene), where Ln = Er, Dy, Yb and H3trensal = 2,2’,2”-tris(salicylideneimino)trimethylamine. These...

Rare-earth (A= La, Ce, Nd, Pr) orthochromites (A CrO3) and orthomanganites (A MnO3) are of interest due to the number of unusual physical properties they possess, displaying...

Understanding the magnetic exchange coupling and fundamental Hamiltonian of the parent compound of FeAs-based superconductors is extremely important, because such information...

Encouraged by many unconventional magnetic properties in the magnetically frustrated spin-chain compounds of the type A3MM'O6, we have recently synthesized a new member...

Cancer is a growing health problem worldwide, and thus the development of effective chemotherapeutic approaches is crucial for improving human health. Much effort has been put...

A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound...

In recent years topologically complex materials have provoked questions about the basic models of magnetism. These materials have given rise to unusual phenomena, including...

Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This...

Ferromagnetic shape memory alloys (FSMAs) are of recent interest because they exhibit a shapememory effect that can be driven by magnetic fields. Thus, FSMAs are important for...

The aim of the experiment is to characterize the magnetic structure of the compound Ce2Ni12As7 using neutron diffraction. At low temperatures the magnetic moments of the cerium...

The increasing demand for portable energy means that the search for new electrode materials for rechargeable solid-state batteries is a key challenge in materials science....

This proposal is concerned with determining the local structure of LaCoO3 and observing changes within this as the material undergoes some well characterised temperature driven...

In the new class of iron pnictide superconductors, there is evidence of phase coexistence close to the phase boundary between the SDW and superconducting order produced by hole...

We are examining various perovskite solid solutions based on NaNbO3 or BiFeO3 that havepromising ferroelectric or multiferroic properties. All of these solid solutions show...

Highly oxidized transition metal cations in oxides tend to display unusual electronic and magnetic behavior due to the highly covalent nature of the M-O interactions. Iron is of...
