Impact of Stereochemistry and Diamine Structure on Absorption of Constructed ...
Chiral gemini surfactants containing stereogenic centers and two amphiphilic moieties, not only maintain the chiral properties, but also exhibit stronger aggregation properties,... -
Exploring Multiferroic Couplings in Ca2MnO4
The Ruddlesden-Popper (RP) compounds An+1BnO3n+1 exhibit a broad range of technologically interesting properties such as high-Tc superconductivity, colossal magnetoresistance,... -
A pair distribution function study of thermoelectric bornites
Thermoelectric materials are attracting increasing attention due to their potential for waste heat energy recovery. The challenge in finding better thermoelectric materials lies... -
Structural behaviour of gallium in phosphate glasses for bone cements
Bone cements are an important class of biomaterial used in hard tissue surgery as well as periodontology. Many of these are glass-ionomer cements formed from an aluminosilicate... -

Our recent high (P,T) developments at PEARL beamline will allow us to study the kinetic and thermodynamic behavior of boron 11B under pressures up to 12 GPa and temperatures up... -
Structure of hot dense liquid carbon dioxide
We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental... -
Structural transformations in pure and Ba-doped PbSc$_{0.5}$Nb$_{0.5}$O$_3$ u...
Lead scandium niobate (PSN) belongs to the class of perovskite-type relaxor ferroelectrics, which are among the key functional materials. Due to their structural complexity, the... -
As2Ch3 glasses: Understanding the relationship between glass structure and no...
We wish to study a series of glasses of composition As2Ch3 (Ch = S, Se and Te) to investigate the effect of varying the chalcogen type on the non-linear optical (NLO) behaviour... -
Structure of novel silica-free titanate glasses
Silica-free barium titanate bulk glasses, containing lanthanide elements, show unusually high dielectric response and a high refractive index. These properties allow crucial... -
Verification of Local Ordering in Praseodymium Doped Ceria
Doped cerias are currently being used as oxide ion conducting electrolyte materials in solid oxide fuel cells (SOFCs). Depending on the nature and concentration of the dopant... -
Measurement of Residual Stresses in Side-Punched Single Edge Notched Bend Spe...
Residual stresses have been generated, mechanically, in single edge notched bend specimens by side-punching ahead of sharp notches. Given that this is a novel method of... -
Neutron Total Scattering of Crystalline Materials in the Gigapascal Regime
Over the past few years, extensive developments have been made in the use of neutron diffraction for structural studies of liquids and amorphous materials at high pressure.... -
High-pressure, high-temperature studies of energetic materials - RDX and HMX
One of the aims of this proposal is to quench to ambient pressure a metastable form of the widely used secondary explosive RDX. This is formed above ~4.5 GPa and 448 K but is... -
PTM dependant polymorphism of acrylamide
Our recent X-ray and single crystal studies have shown that acrylamide can undergo different phase transformations depending on the pressure transmitting medium used i.e.... -
A high pressure structural study of the charge transfer complexes trimethylam...
We propose a high-pressure powder neutron diffraction study of the archetypal donor-acceptor complexes (CD3)3N...I2 and (CD3)3N...ICl . These are the simplest structurally... -
High pressure behaviour of sulfuric acid tetrahydrate
Our previous work on sulfuric acid tetrahydrate (SAT) identified a monoclinic high-pressure polymorph, which forms at 5.35 kbar when the tetragonal low-pressure phase is warmed... -
Structure Solution of the High-Pressure Polymorphs of Hydroxylamine
This proposal requests the allocation of six days beamtime on PEARL to collect neutron powder diffraction data suitable for the structure solution of phases II and III of... -
CuH: a continuing (nearly) 200 year old problem (TOSCA)
CuH was first prepared by Wurtz in 1844 by the reaction of aqueous copper sulfate with hypophosphorous acid. Several other routes have been developed including precipitation of... -
Structural changes in 320GB Blu-ray disc based on BiOx glass
Japanese company TDK has recently developed a 320GB optical storage disc. In contrast to usual DVDs and BDs, the 320GB TDK disc seems to operate because of difference in... -
Evolution of the structure of the Li/ND3 intercalate of FeSe with pressure
This experiment follows our ambient pressure characterisation of the Li intercalate of FeSe which is a superconductor with a Tc of 43 K. Li atoms, amide ions and ammonia...
