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... -
Does tethered PEG behave as a typical polymer brush at the solid-liquid inter...
We propose to make neutron reflectivity measurements of hydrophillic polymers covalently attached, via thiol chemistry, to the gold-water interface. In particular, we will... -
Temperature induced structural phase transitions in BaPrO3 and acceptor doped...
The sequence of structural phase transitions that occur in distorted ABO3 perovskites as a function of temperature is of intrinsic interest for better understanding of the... -
Surface structures of polycations in confined geometries
A second-generation surface force style apparatus has been developed to probe the inter-surface and near-surface structures under compressive forces. Systems of current academic... -
Degenerate ground-states in Ho2-xYxSn2O7
Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the... -
Investigating the effect of pore structure upon interactions of hydrogen with...
Three MOFs samples with high hydrogen storage capacities at 77K, and high surface area, are willing to be analyzed. In order to investigate hydrogen interactions within the... -
Magnetic excitations in CrB2
CrB2, like MnB2, are transition metal diborides that have magnetically ordered ground states. Preliminary neutron (TAS) work and in house lab indicated that the dispersion has... -
Temperature dependence on mangetic excitations from the high Tc cuprate BSCCO
We plan to continue inelastic neutron scattering measurements on the high Tc cuprate superconductor BSCCO with optimum doping. In the proposed experiment, we will have about 40... -
Interactions between a polymer brush grown from a macro-initiator-modified sa...
We propose to make neutron reflectivity measurements of the weak polyelectrolyte, poly(dimethy amino ethyl methacrylate), grown from two different surface densities of initiator...
