Water librations in proton conducting hydrated alkali thio-hydroxogermanates
We propose to perform a systematic study of the intermolecular librational mode of molecular water in the proton conducting hydrated alkali thio-hydroxogermanates... -
Electric field induced swelling/collapse of strong polyelectrolyte brushes
Electric field induced changes in the swelling of a strong polyelectrolyte brush will be investigated using neutron reflectivity. A poly(styrene sulphonate), PSS, brush will be... -
Probing the structure of calcium silicates over a wide range of length scales.
Sol-gel derived calcium silicates are of great importance due to their ability to bond to bone and stimulate new bone growth. Diffraction has revealed the atomic-scale changes... -
Dynamic ferromagnetic domains in a frustrated 1-d chain system
We propose to carry out a small angle scattering experiment on LOQ or SANS2D on a frustrated Ising chain system. SrHoCrO6 is based on ferromagnetic chains arranged on a... -
Insoluble layer formation in polymer bilayers
In a previous neutron reflectivity(NR) measurement (RB620370) on CRISP, we showed that the insoluble interlayer formed between the charge injection layer and a semiconducting... -
Charge disproportionation and structural modulation in multiferroic CaMn7O12
Multiferroic materials in which strongly coupled magnetic and ferroelectric order parameters coexist attract considerable interest. Below 90 K, CaMn7O12 possesses the largest... -
