Pyrochlore to Defect- Fluorite Transition Studies in Holmium-Titanate based Composition using Neutron Powder Diffraction Technique-2

YbAl3C3 undergoes a structural phase transition at 80 K and a spin-dimer formation below 10K. To gain more information on the nature of the spin-dimer state and the phase...

An intriguing unknown variant of the nematic liquid-crystal phase (Nx) has been discovered first in a class of main-chain polymers, and later in LC dimers connected via an...

We shall use small angle neutron scattering to investigate the structural behaviour of the temperature sensitive highly branched poly(N-isopropyl acrylamide) [PNIPAM]. These...

[2,2]-Paracyclophane, C16H16, is a small molecule containing both sp2 and sp3 hybridized carbon atoms. Despite of its apparent simplicity, its solid state structure and...

The fcc polymorph of the hyperexpanded fulleride Cs3C60 can be driven to a bulk suprconducting state without symmetry change by the application of pressure. Its Tc passes...

This experiment is part of a programme to study the effect of applied electric fields on the structure of biomimetic films formed at Au electrodes, with emphasis on...

It has very recently been shown that Mott-insulators located at the crossover regime closer to the itinerant side, such as RNiO3, undergo a pressure-induced transition into a...

We propose to continue our search for the Kasteleyn transition in the kagome ice phase of the spin ice Ho2Ti2O7. The experiment requires the applied magnetic field to be...

We have been recently successful in isolating the fcc polymorph of the key hyperexpanded fulleride Cs3C60 - this phase can be driven to a bulk suprconducting state without...

High resolution powder diffraction data will be used to obtain lattice parameter and atomic coordinate variations as a function of temperature for Pr0.6Ca0.4MnO3, which has a...

In a previous SAXS experiment at Max-Lab (Sweden) we observed that the thermotropic mesophase transitional behaviour of the monoolein(MO):cholesterol:water system was...

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...

Hybrid organic-inorganic perovskites are interesting candidates for a range of applications, from solar cells to light emitting diodes and lasers. For the latter applications...

The proposal consists of two parts. Firstly, we will undertake an ambient temperature ex-situ PND study of some new ternary transition metal carbide phases that have been...

During the course of a PhD project funded by CCLRC's CMPC, we have developed a cell that allows electrical transport property measurements to be made simultaneously with the...

Here we propose to investigate the fluroide containing compounds - AgF2, CuF2 and Cs2CuF4. By taking advantage of the F-mu-F coupling wich occurs in these compounds, we will...

In the present project we will focus on critical behaviour of Cu3(pyrazine)[W(CN)8]2 revealing magnetic phase transition at Tc=43 K. The findings will be compared to those...

Apatite-type phases have been attracting interest as a new class of oxide ion conductors, and in these systems, the key defects are oxide ion interstitials. We have recently...

BiNiO3, synthesized at high pressure, has the unusual charge distribution Bi3+0.5Bi5+0.5Ni2+O3 with ordering of Bi3+ and Bi5+ charges on the A sites of a highly distorted...
