The high-pressure forms of ice, phases III and V, are the equilibrium solids in contact with liquid water at pressures between 2.5 - 5.5 kbar. Consequently, their properties are...

Ti2AlN and Ti4AlN3 are MAX phases that exhibit a unique combination of the characteristics of both ceramics and metals coupled with an unusual combination of mechanical,...

Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crysta. There are outstanding...

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...

hard carbon are promising anodes for sodium ion batteries, due to their high capacity and green production from biowaste. However, they require treatment at very high...

Hydrogen hydrates are good potential hydrogen storage materials because they are both cheap and environmentally passive. This proposal is to study the crystal structure and...

On exposure to ammonia, LiBD4 and Mg(BD4)2 form the respective ammoniates, Li(11)BD4(ND3)n and Mg((11)BD4)2(ND3)6. We have identified the decomposition temperatures, kinetics...

This proposal seeks to identify and characterise the adsorption of primary linear amides that adsorb to the surface from the bulk of a polymer melt. These layers are...

Methylamines are an ideal chemical system to study in order to understand the effects of steric bulk and competing non-bonding interactions on hydrogen bonding at the networks...

The use of the J 0-to-1 rotational transition of dihydrogen has been extensively used to characterise the state if hydrogen in and on materials. The disadvantage of studying the...

We have recently performed a ZF muon experiment on Ba3Dy2GaNb9O30 in EMU under the influence of electric fields and demonstrated that this material demonstrates multiferroic...

We request 3 days on POLARIS to study the detailed crystal structure of a sodium battery cathode material that is currently under consideration for use in commercial sodium...

Recently [RB 900007], we have demonstrated that it is possible to determine the detailed site-by-site behaviour of hydrogen during in-situ absorption and desorption in metal...

Water displays a highly complex phase diagram that is key to a range of critical processes, from the evolution of icy moons to that of the Earth's hydrosphere and even of life...

Multiferroic materials which exhibit both ferroelectric and (anti)ferromagnetic ordering are of great technological importance offering the potential for the design of novel...

MAX phases exhibit a unique combination of the characteristics ofboth ceramics and metals coupled with an unusual combination of mechanical, electrical and thermal properties....

In recent years, the long-standing belief that beyond the critical point, matter exhibits no clear transition between liquid-like and gas-like states has been questioned. A line...

Cemented carbides are composite materials manufactured via powder metallurgy. The excellent wear resistance, high hardness, and high toughness make them widely used materials in...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...

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...
