Ocean warming and acidification can have negative implications on coral reefs. This mechanistic study aims to evaluate the proximal causes of the observed negative response of...

Recent studies of short side chain(SSC) polymers used in fuel cells have shown that they have higher conductivity and better structural properties than Nafion, the commercially...

We propose to measure the incoherent neutron spectra of lithium amide (LiNH_2) and imide (Li_2NH) at low temperature (T<20 K). These two substances belong to the Li-H-N...

Croconic acid has recently emerged as the first example of an above room-temperature organic single component ferroelectric. Our goal is to determine its crystal structure at...

The fluorinated ionomer Nafion is a material that provides efficient proton conducting membranes for application in important technological areas such as hydrogen fuel cells....

We request 4 days on VESUVIO to study the proton, lithium and oxygen momentum distributions in a series of HxLiyWO3 bronzes (including the protonated bronze HxWO3). VESUVIO has...

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...

In the proposed experiment ammonia borane (NH_3BH_3) will be investigated through incoherent inelastic neutron scattering on TOSCA at low temperature. Since it is well known...

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...

We propose to measure the dynamics in ZnADP¿3H2O, a new and high performance material that exhibits proton conductivity as high as Nafion membranes, which is the best commercial...

Earlier experiment at ISIS have shown that water responds to the distortion of the hydrogen bond network by delocalizing some of the protons in the vicinity of the defects. That...

Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the...

Super proton conductors are in the focus of interest because of their use in low temperature fuel cells. In this project we try to obtain information on proton mobility,...

we propose deep inelastic neutron scattering measurements on VESUVIO to investigate the short time proton dynamics in Li2NH. The latter belongs to the Li-H-N system, which has...

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...

The fluorinated ionomer Nafion is a material that provides efficient proton conducting membranes for application in important technological areas such as hydrogen fuel cells....

Upon the addition of Li to anhydrous ammonia, the famous Li-Ammonia solutions form through an intriguing metal-insulator transition. These have been studied intensely for many...

Hydrogen bonds are ubiquitous in materials across the chemical spectrum, from inorganic to biological. They influence the structure, the functionality, and therefore the...

Ethylene glycol is an industrially important alcohol used as anti-freeze. The presence of intra and inter-molecular hydrogen bonding in its liquid and solid state form makes the...

We request 7 days on VESUVIO to study the molecular crystals 7Li(NH3)4X (X=I, Br, Cl , F) and parent halides, 7LiX (data for 7LiF and 7LiCl already exists). This proposal is...
