Topotactic reduction of YMnO3 with CaH2 yields three new reduced phases. Two of these phases appear to have compositions close to YMnO2.5 but with very different anion vacancy...

The aim of this experiment is to determine accurately the crystal structures of phases in the (1-x)BiScO3-xPbTiO3 (BST-PT) perovskite phase diagram, particularly in the vicinity...

Previous studies have attempted to correlate the results of metallography with neutron diffraction studies on the very high-carbon steels used in Oriental blades, and Indian...

Multiferroic materials are rare and exceptional: they are ferroelectric and ferromagnetic in the same phase and these two properties can couple. Recently, materials with complex...

An uncommon oxygen absorption/desorption behavior for cobalt oxide YBaCo4O7+d was found[Karppinen et al. Chem Mater 18 2006 490]. Y114 absorbs and desorbs oxygen up to d = 1.5...

New types of water-in-CO2 microemulsions using mixed surfactant systems will be investigated by high-pressure SANS (HP-SANS). Exciting new results (see report on RB820030) have...

BiFeO3 is a rare example of multiferroic material with a simple perovskite-like structure, having extremely large magnetic ordering temperature (TN = 650 K) and Curie...

We propose to use NR to study the structural features of the model wheat wax films formulated from the known main components of long chain primary alcohols and an ester. By...

Over the past two years I have carried out high-pressure surveys of the ammonia monohydrate (AMH) phase diagram using a Paris-Edinburgh press mounted on the D20 beam-line at the...

The proposal involves the non-invasive measurement of ancient Roman coins by ToF diffraction techniques. A well selected series of Victoriati are to be measured in order to...

We propose to measure the inelastic scattering S(Q,E) maps from barium in both the polycrystalline and liquid phases, based on the fact that there are intriguing similarities...

We request 6 days of HRPD time in order to study the structures on the tetragonal side of the lead zirconate-titanate (PZT) phase diagram, a region that has so far been rather...

We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the...

The objective of this experiment is to characterise four particular high-pressure polymorphs of various hydrates discovered by us in recent years during work carried out using...

This proposal aims to explore these dispersed lamellar phases with a variety of F7H4 derivatives,to help understand their formation in supercritical CO2 (sc-CO2). The focus is...

In a series of in situ neutron diffraction measurements from deuterium up-take in Li3N, the present authors have identified a novel non-stoichiometric 'quasi-imide' of...

Following our investigation of alpha-orthorhombic sulphur, we will measure level crossing spectra of some other allotropes and phases, to find if the muon radical observed in...

This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages,...

Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type...

This proposal follows on from our successful experiment on ENGIN-X lin 2006, where we measured the development of strains in the aluminium and silicon phases of a common casting...
