A promising class of materials for solar energy is conjugated polymer (CP)-fullerene mixtures. They offer the future potential for replacing current inorganic systems with...

Although the surface properties and self-organisation of end-functional polymers in amorphous blends are well understood, the influence of crystallinity has received little...

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...

Ammonia is seen as a key part of the transition to a sustainable energy economy, but needs decomposition catalysts to release its stored hydrogen. Lithium nitride-hydride...

NOx emissions from the energy and transport sectors represent a major hazard to human health and this has been the focus of significant industrial and academic research. One of...

In the current work, we study inorganic solid-state electrolytes for lithium-ion batteries. These materials, unlike the traditional liquid electrolytes, could lead to a...

The search for a light, high-capacity hydrogen store continues. Ammonia borane (AB) is a complex hydride with excellent hydrogen capacity, of which half desorbs at moderate...

Cooling down a liquid at ambient pressure all except Helium attain a solid state. If a crystalline state is reached a dramatic change in long range order occurs manifesting the...

As a natural continuation of RB1010524, we propose to perform NCS measurements on CsHSO4 around the super protonic phase transition at 414 K. Our methodology to compute atomic...

Due to the importance of developing efficient biomass conversion processes, the mobility of lignin constituents phenol and catechol in zeolite Beta will be studied using QENS....

We wish to collect powder neutron diffraction data as a function of temperature to investigate structural changes through a phase transition in the parent thermoelectric phase...

In Sheffield, 9% efficient organic solar cells have been made using a new non-fullerene acceptor called ITIC, when blended with semiconducting polymers. GIWAXS measurements have...

The compound, Si5O(PO4)6, is a component of a solid phosphoric acid catalyst, it has highly unusual coordination of the silicon (octahedral, as well as the more common...

Free volume theory has successfully predicted and described all of the liquid-to-solid transitions in hard sphere system. However, in polymer system, the exact molecular picture...

Zinc Oxide (ZnO) is a wide band gap semiconductor that has a number of interesting applications especially its optoelectronic (blue and near UV light emitting properties, as a...

We propose to study two aspects of the hydrogen dynamics in complex hydrides:First: The structural transitions in borohydrides are believed to be connected with an increase in...

Lubricants contain a complex mixtures of polymers and base oils that must provide protection to moving surfaces with minimal energy loss due to friction or viscous drag. There...

The synthesis of a phase combining electrical polarisation P and spontaneous magnetisation M is hard because of the distinct electronic structure requirements for the main...

We propose to use Polaris to record powder neutron diffraction data for the oxygen deficient double perovskite Sr3SbO5.5 as a function of temperature to establish the...

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...
