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...

Hydrogen storage is considered to be one of the principal technological barriers in the transition towards a hydrogen-based economy. In this proposal, we plan to look at the key...

We ask for 4 days beam time on GEM to study the dehydrogenation and subsequent rehydrogenation of Mg(11BD4)2. Mg(BH4)2 is currently one of the most promising lightweight...

Despite the large research effort that has been made, the microscopic processes of hydrogen chemisorption on graphite is not well understood. By ball milling graphite for a...

On exposure to ammonia, Li(11)BD4 forms the ammoniate Li(11)BD4(ND3)n. Our recent experiment (RB820252) has shown that there are four distinct crystalline phases in the...

The development of high energy density and high efficiency hydrogen storage materials is widely considered to be one of the most challenging barriers to the adoption of fuel...

Bimetallic alloy catalysts with optimized metal ratio usually exhibit a superior catalytic hydrogenation activity and selectivity compared to individual mono-metallic catalysts,...

We request 4 days on HRPD with the IGAn apparatus to follow the structural changes of Me-ND4 11BD4 as a function of temperature. The high resolution of HRPD will allow us to...

Early transition metal carbides and nitrides catalyze a variety of chemical transformations from gas- and solution phase hydrogenations, to the water-gas-shift reaction. The...

As part of a PhD study our research team is investigating protonic conduction in cerium and yttrium doped barium zirconate (BZCY) prepared by Spark Plasma Sintering. Previous...

We request 4 days on HRPD to perform combined specific heat and neutron powder diffraction measurements of C60 and the molecular hydrogen storage materials, ammonia borane and...

We have constructed a novel microwave frequency resonator that can sit within the GEM and POLARIS diffractometers and will allow us to simultaneously collect diffraction and...

The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen...

Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data...

Nitrides of alkali and alkaline earth metals are an interesting set of materials specifically for their potential in reversible hydrogen storage. However, many fundamental...

We request 3 days on GEM to perform in-situ neutron diffraction and electrical conductivity studies of LiBD4 (crystalline and after quenching from 500K) and 0.33LiI.LiBD4 as a...

Catalysts used for water-gas shift reactions, and other important industrial processes, often suffer from deposition of hydrocarbon and carbon species (coking) to reduce their...

We ask for 8 days on VESUVIO to study the momentum distribution of LiBH4, Li2NH and Li1+xNH2-x as a function of temperature from 10K-653K (depending on sample). Li2NH and...

Bimetallic alloy catalysts with optimized metal ratio usually exhibit a superior catalytic hydrogenation activity and selectivity compared to individual mono-metallic catalysts,...

Ammonia Borane (AB), NH3BH3, was first synthesised in the 1950s and has now become the focus of a world wide research program with regards to its potential as a hydrogen store....
