Inelastic Neutron Spectroscopy Study of Ammonium Borohydride
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... -
Local structure study of the order/disorder ferroelectric transition in [ND4]...
We will carry out a definitive local structure investigation of the ferroelectric transition in [ND4][Zn(DCOO)3]. This compound is seen as the canonical example of a... -
High-pressure studies of inorganic azides
This proposal seeks to identify and structurally characterise the high-pressure phases of the azide salts of sodium, silver, lead, and the ammonium ion. Azides are examples of... -
The Pressure and Temperature Dependence of the Structure of Ammonium Triiodide
We have shown that the molecular ionic solids MI3 (M=Tl, Cs, Tl, NH4) undergo structural phase transitions below 3.4 GPa at RT to give the same new high pressure phase (HP) with... -
Search for magnetic fluctuations and a spin resonance in FeSe intercalated wi...
Very recently, bulk superconductivity has been found at Tc = 43 K in the layered compound FeSe intercalated with Li ions and amide and ammonia molecular groups. We propose to... -
Structure, thermal expansion and vibrational properties of ammonium bicarbona...
Ammonium carbonates, sensu lato, have relevance to carbon capture schemes and as potential hydrogen storage materials. These compounds occur on Earth as minerals and, since... -
Adsorption kinetics from polymer/surfactant systems; PSS/CnTAB
Polymer-surfactant mixtures are widely used in commercial formulations in personal care, pharmaceutical and agrochemical, cleaning, automotive and food industries. The... -
Proton/deuteron mobility in ammonium hexachlorometallates.
The piloting experiments RB820478, RB610497 and RB 10067 on VESUVIO on (NH4)2PdCl6 and (NH4)2TeCl6 have shown that: (i) at 300 K, the dynamics of NH4+ and PdCl6- and TeCl6- is... -
High-pressure, high-temperature studies of energetic materials - FOX-7, CL-20...
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of 3 important energetic materials - FOX-7, CL-20, and ADN. These experiments are expected... -
Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crysta. There are outstanding... -
Study of NH4+ mobility in ammonia borane, ammonium borohydride and methyl amm...
We request 5 days on EMU to study the NH4+ ion mobility in the light borohydride materials NH3BH3, NH4BH4 and CH3NH3BH4. As has been proposed by Stowe et al., during the... -
Vibrational density of states in ammonium hexachlorometallates.
The piloting VESUVIO experiments RB820478, RB610497 on (NH4)2PdCl6 and (NH4)2TeCl6 and RB 10067 on (ND4)2PdCl6 have shown that: (i) the H/D dynamics in NH4+/ND4+ is largely... -
Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crystal. There have been no... -
Onset of classical dynamics in ammonium hexachlorometallates.
The piloting experiment (RB 820239) on VESUVIO on (NH4)2PdCl6, has shown that, at 5 and 80K, H momentum distribution, J(y), in NH4+ is non-Gaussian with non-vanishing... -
