Study on the effect of polymer dynamics to the transport properties and macro...
We use inorganic nanoparticles grafted with polymers as membranes for gas separation. These membranes show remarkable enhancement in permeability as compared to the bulk... -
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... -
Superstructures in insulating and metallic lanthanum-doped sodium cobaltate
The thermoelectric properties of NaxCoO2 can be substantially improved by replacing Na ions by cations of higher valence. Our neutron diffraction studies on SXD for doping with... -
Structure and Phase Transitions of XNbOP2O7, with X = ND4 and Rb
In this proposal we request 3 days of beam time on HRPD to study the structure and phase transitions of XNbOP2O7 (X = Rb and ND4). These materials have been shown to undergo... -
Li-ion diffusion in the solid electrolyte LLT
The high voltage and energy density has made lithium-ion batteries ubiquitous in portable electronics, such as iPods, laptops and mobile phones. At present, they are typically... -
Jump diffusion of small molecules in polymers influence of grafting on the ...
The concept of diffusion of light gases through polymers is a widely used in a variety of commercially available materials - food packaging materials, solar cell encapsulants,... -
Magnetic and charge ordering, superstructures and diffuse scattering in de-in...
Sodium Cobaltate has a complex phase diagram, exhibiting various phenomena and a kaleidoscope of superlattice diffraction patterns as the concentration of sodium is varied. It... -
Two-Dimensional Incommensurate Modulation in Melilite
We have prepared large single crystals of the melilite electroltyes Ln1+xCaxGa3O7+d; (Ln = La and Nd; x = 0 and 0.5) using a floating zone mirror furnace. We have characterised... -

Detailed characterisation of metastable phase fractions in ZrW2O8
Cubic alpha-ZrW2O8 is the classic example of a material exhibiting the unusual property of negative thermal expansion (NTE). Despite this effect having been discovered 20 years... -
Phase Separation in NaTaO3. Can it be controlled by pressure?
The present proposal seeks to establish the pressure dependence of the Pbnm-Cmcm transition in NaTaO3 and some doped variants thereof. It aims to understand the understand the... -
Molecular weight dependence of 2D-confined dynamics in glass-forming systems
We seek to explore the dynamics of glass forming systems upon extreme 2D-confinement. These experiments are motivated by preliminary experiments on oligomers and macromolecules... -
Thermal equations of state for kyanite, andalusite and sillimanite
The three Al-silicate polymorphs, kyanite, andalusite and sillimanite, are well-known geological markers used to determine the extent of P- and T-induced metamorphism... -
Investigation of segmental dynamics in polymer nanocomposite glasses with gra...
Polymer nanocomposites are formed by embedding polymer grafted nanoparticles in homopolymer host matrix. Polymers form glasses when cooled through their glass transition... -
Hydride-ion mobility analysis of SrVO2H using quasielastic neutron scattering
The proposed experiment at ISIS aims at the characterization of the diffusional motion of the hydride-ions in SrVO2H, which possesses the highest H (hydride) content among... -
A QENS Study of Guaiacol, a Lignin Model Compound, on a Hydrodeoxygenation Ca...
Bio-oil can be obtained from the pyrolysis of biomass and maintains a closed carbon cycle with no net increase in atmospheric CO2 level, making the environment cleaner. However,... -
Investigation of phonon anomalies in the CDW phases of 1T-TaS2
1T-TaS2, an archetypal quasi-2D compound, reveals strong electron-phonon (e-p) coupling responsible for charge-density-wave (CDW) instabilities leading to a series of phase... -
Local structure of ortho-terphenyl glass
Ortho-terphenyl is a paradigmatic example of a molecular glass-former; yet the structure of its glass has never been fully described. We have recently demonstrated that, by... -
Inelastic Neutron Scattering study on new tetragonal compound Ce2PdGe3
Cerium-based Kondo lattice compounds have received great attention, owing mostly to the variety of exotic ground states that they exhibit (e.g., unconventional... -
Crystal and Magnetic structure of CoFe3O5
A recent exciting development in magnetic materials was the discovery of a new iron oxide, Fe4O5, using high temperature and high pressure. A very recent structural study has...
