Exploring Polymer Vibrations under Extreme Confinement: Substrate Effects
We seek to explore extreme confinement on the vibrational density of states of polyethylene oxide (PEO) over a wide energy-transfer range (10-3000 cm-1). These experiments are... -
Dynamics of Polymer/Polymer nanocomposites
By adding only about 1% of soft polymer nanoparticles to natural rubber, a dramatic decrease in the viscosity (more than 50%) is induced. Our recent time of flight measurements... -
The use of INS to characterise deactivation of methane reforming catalysts.
For the first time, the research team aim to use INS to characterise a series of candidate methane reforming catalysts. Recent studies have shown that modification of... -
A variable temperature study of polymorphism in Li2+2xM1-xSiO4 electrode mate...
There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap andsafe cathodes. Recently, silicate-based cathodes have been described,... -
Unusual polymorphism in sodalites
We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible... -
Analysing intermediates of a CO2 insertion reaction using simultaneous operan...
Atmospheric levels of CO2 are increasing at uncontrolled levels and as such methods of CO2 utilisation are being researched. A key reaction for this purpose is the coupling of... -
Structures and magnetism of chemical and electrochemical deintercalates of la...
We propose to use OSIRIS to investigate the changes in magnetic ordering which occur when a series of layered oxysulfides with mixed-valent Mn ions in their oxide layers are... -
Local structural disorder in the ion conducting complex oxide CeNbO4+d
Complex oxides within the family CeNbO4 have been shown by single crystal x-ray studies to have superstructured average structures, but little detail has been obtained about the... -
Effects of interlayer confinement and hydration on capacitive charge storage ...
Nanostructured birnessite (δ-MnO2) exhibits high specific capacitance and nearly ideal capacitive behavior in aqueous electrolytes, rendering it an important electrode material... -
Revealing the structure and oxygen transport at interface in complex oxide he...
Vertically aligned nanocomposite (VAN) films, comprising nanopillars of one phase embedded in a matrix of another, have shown great promise for a range of applications due to...
