This experiment will establish the structural changes that occur in Amorphous Solid Water (ASW) prior to the process of pore collapse or crystallisation. We will study the...

Very rapid quenching of liquids to form a glass, from which crystalline phases are subsequently obtained by devitrification, is a powerful technique for obtaining novel...

The concept of an aristotype, or equivalently, the basic structure, that represents the highest symmetry crystal structure that can be attained, either experimentally, or...

Hexagonal close packed (HCP) alloys have a wide range of industrial uses, including within the nuclear industry and for aerospace applications.The properties of HCP alloys are...

The hybrid organic-inorganic perovskites are of great interest as functional materials, because they combine the well-established perovskite topology with new physics and...

The aim of this experiment is to complete the understanding of the complex nature of the structural and magnetic interactions in the La0.7Sr0.3Mn1-xFexO3 series of materials in...

We will use off-specular reflectivity to probe the characteristic lateral length-scales in responsive polyelectrolyte brushes grown by surface-initiated ATRP from solid-liquid...

Barocaloric materials, in which a large isothermal entropy change is associated with a pressure induced phase transition, offer an alternative to vapour-compression technologies...

One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution...

The perovskite-structured phases and their associated phase transitions remain an enduring topic of study within the solid state sciences due to their importance in both applied...

Ionic liquids (ILs) are gaining increased interest as electrolytes given their thermal and chemical stability, wide electrochemical windows, and ionic conductivities. However,...

Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such...

This proposal is part of our research programme on spin and orbital order in frustrated systems. AgNiO2 has a layered crystal structure with Jahn-Teller active Ni3+ ions forming...

One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or...

The crystal structure of the intermetallic PrFe2Al8 consists of a network of Al which forms quasi cage-like structure where the Pr and the Fe form chains of atoms along the...

We request 3 days’ beam time on POLARIS for in-situ powder diffraction studies of the reactions of lithium amide or lithium imide with manganese(IV) oxide under flowing argon or...

Ferroelectric polarization in type-II multiferroics is induced below long-range magnetic ordering with certain magnetic structure that breaks the inversion symmetry. Here we...

Metal oxides(MO) are widely used in technological applications especially for catalysts and supports for catalysts. We propose to use the inelastic response of H2 adsorbed on...

With the discovery of almost 3000 exo-planets it is clear that planet formation is a by-product of star formation, yet in the micron ? cm size range, where relative velocities...

Like the well known perovskites, the double perovskites A2BB'O6 form an enormous family of compounds exhibiting a wealth of phenomena ranging from magnetic long range order,...
