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...

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...

The objective of the proposed experiment is to develop an understanding of the Li/Ni/Mn ordering in a commercially relevant lithium ion battery positive electrode,...

Ammonia has been proposed as a high density chemical energy-storage media, which can be safely and reversible stored within low cost saline halides. Here we propose to extend...

Phenol-water and phenol-ammonia clusters are useful model systems for understanding the types of proton-transfer interactions that occur during photosynthesis in plants and...

Organic ferroelectrics are in the focus of current research because their potential applications as a material to address global challenges. These lightweight, flexible and...

Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric...

Antiferromagnetic S = 1 one-dimensional chains exhibit a myriad of magnetic ground states depending on the balance between the spin exchange parameter and the single-ion...

The ambient-pressure phase of ice is a well-known example of a molecular solid that exhibits negative volume thermal expansion below 60 K. In a recent study carried out on HRPD...

This proposal requests the allocation of six days beamtime on PEARL to collect neutron powder diffraction data suitable for the structure solution of phases II and III of...

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...

Clay barriers are routinely used in nuclear waste repositories to isolate radionuclides from the biosphere. Such barriers have to be carefully designed to remain effective for...

Flexible functional materials are important candidates of current research, because of their potential applications in plastic electronics. Organic ferroelectrics are one of...

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...

In previous experiments at ILL we observed a gap in the magnetic excitation spectrum of the stripe-ordered superconductor (La,Nd)2-xSrxCuO4, x=0.12. We observed a spin gap of...

SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of...

In recent high pressure experiments (S. Klotz et al., Nature Materials, DOI 10.1038/ NMAT2422, 23.4.2009) we discovered a salt hydrate based on a high-pressure ice form, i.e....

We will investigate the structure of 4-chloroimidazole a material, which undergoes extreme anisotropic thermal expansion,.as a function of pressure at a range of temperatures...

Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical...

Metal-organic framework materials are a topical family of nanoporous solids that have potential applications in molecular storage, separation and catalysis. Some of these...
