We request 4 days of beamtime on SXD in order to locate the protons and quantify their ordering within the structure of hopeite Zn3(PO4)2.4H2O. Hopeite is an important phase in...

This proposal is part 2 of a set of two proposals on Offspec aimed at understanding some of the effects seen in off-specular data and in particular the use of the spin echo...

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...

For polymer vesicles to act as effective molecular delivery systems we must efficiently encapsulate a molecular payload within the vesicle. We would like to use neutron...

There is a pressing worldwide need for research to develop specific sustainable spent fuel reprocessing technologies suitable for minimizing waste from next generation nuclear...

We ask for 8 days of beam time on CRISP to study the absorption and desorption of hydrogen and deuterium in Ti/Mg/Pd trilayer samples. Our specific objective is to understand in...

We propose a high-pressure powder neutron diffraction study of the archetypal donor-acceptor complexes (CD3)3N...I2 and (CD3)3N...ICl . These are the simplest structurally...

ZrMn2H3 is a Laves Phase intermetallic hydride with interesting materials properties - unlike most Laves Phases, the parent alloy ZrMn2 is not a line phase but has a wide range...

Ammonium borohydride (ABH2) has been studied as a hydrogen storage material, it stores hydrogen on both cationic and anionic sites and has the largest gravimetric and volumetric...

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 Earth¿s climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects cloud droplet size and optical properties, important climatic...

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...

Ammonia borane (AB) is one of the most promising hydrogen storage materials. There has recently been work on a more mobile phase of AB (denoted AB*) which is formed (via the...

King Henry VIII's flagship, the Mary Rose, offers a unique insight into Tudor life. As well as her value as one of the first purpose built warships of the modern period,...

Antioxidants are receiving increased attention for their potential effects in the prevention of chronic and degenerative diseases such as cancer and cardiovascular disease as...

Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work...

Our main objective in this proposal is to study the competition between halogen and hydrogen bonding as a function of temperature in the complex (CH3)2C=O--- Br2. The results of...

Our intention is to study the INS spectra of ammine complexes nNH3LiBH4 (with n = 1,2,3,4) and nNH3LiI (n=1). Ammine complexes (MXm(NH3)n), amides (M(NH2)m), and imides...

The interaction of ammonia with binary hydrides (prototypically, the interaction of LiH with ammonia gas) is thought to be the predominant interaction for hydrogen production...

Our understanding of chemical reactivity is founded on the fundamental concepts of Electrophilicity and Neucleophilicity. There are a number of attempts of limited applicability...
