Phonon measurements of the incommensurate phase transition in Åkermanite
The proposal is to measure the inelastic scattering from a single crystal of Åkermanite on cooling towards and through the incommensurate phase transition at 358 K. There are... -
The effect of unsaturation on the shear dependence of cationic lamellar phase...
Products such as fabric and hair conditioners are commonly in the form of di-alkyl chain cationic lamellar phase dispersion. The effects of shear on such lamellar phase... -
How molecular solids prepare for phase transitions: The phase transition in o...
Oxalyl chloride (mpt. 260 K), forms an ordered phase at low temperature, but a disordered phase between 250 K and the melting point. In previous beamtime we aimed to carry out... -
The topotactic reduction and anion exchange of complex oxy-halides
The reaction of LiH with the oxy-chloride Sr3Fe2O5Cl2 initially leads to the topotactic deintercalation of oxide ions and the formation of Sr3Fe2O4Cl2 containing sheets of... -
Study of structural and phase transitions of carbon dioxide confined in the n...
When fluids are confined in pores with dimensions in the nanoscale, their properties differ from the bulk mainly due to the solid-fluid interactions and the finite pore size.... -
Quantitative determination of the phase distribution of an iron tool from a B...
We propose to measure a fragment of a tool, coming from a Bronze Age burial ground of southern Tuscany, which seems to be forged of iron but does not fit with the attributed age. -
Investigation of excitonic physics in polycyclic aromatic hydrocarbon molecules
The MuSES project currently ongoing in the HiFi spectrometer gives unique opportunity in the field of photochemistry and photophysics of organic molecules. After two successful... -
Magnetic structure of the potential multiferroic GdCrO3
Because of the potential applications of multiferroicity, the discovery of a new multiferroic (MF) material is invariably met with great enthusiasm in the condensed matter... -
Probing phase transitions in vanadium oxide polymorphs using muons
Vanadium oxides have attracted considerable attention, not only due to their potential technological applications, but also because of the rich variety of structures and... -
Spin wave excitations of chiral magnet Fe3PO7
In a magnetic system, besides the common homogenous magnetic configuration, there also exist interesting and useful magnetic defects, and they are linked to novel topological... -
Excitations, BEC, and partially ordered states of liquid 4He in disorder
We propose measurements of the elementary phonon-roton (p-r) excitations of liquid 4He confined in porous MCM-41 (45 Å pore diameter) at wave vectors Q ¿ beyond the roton¿, 2.4... -
Pressure dependence on the isomorphic phase transition in KOs2O6
We are requesting 5 days of beamtime on HRPD to measure powder diffraction patterns of KOs2O6 under He gas high pressure up to 150 MPa. KOs2O6 exhibits a novel phase transition... -
Field induced spin Luttinger liquid phase in a spin ladder
Spin ladders present a class of low dimensional quantum magnets that occupy a regime of subtle behaviour which lies between the stark extremes of a one-dimensional chain or... -
Oxidation of bilayer of labelled DPPC by aqueous hydroxyl radical elucidati...
Oxidation of atmospheric aerosol can produce cloud condensation nuclei capable of changing the reflectivity and lifetime of clouds. The oxidation of organic film on atmospheric... -
Inelastic Spectroscopy of the Mobile Phase of Ammonia Borane
Ammonia borane (AB) is one of the most promising hydrogen storage materials. There has recently been work on a more mobile phase of AB (denoted AB*) which is formed (via the... -
High resolution INS spectra of hydrocarbonaceous overlayers formed on novel m...
For the first time, the research team aim to use INS to characterise a series of new high specification methane reforming catalysts. The enhanced performance of these catalysts... -
Inelastic neutron scattering investigations of the high temperature phase tra...
Recently it has been reported that YbAl3C3 undergoes an antiferromagnetic quadrupolar ordering transition at 80 K, Further study by Ochiai et al. revealed that the transition at... -
Studying the limits of the quantum Griffiths phase in Ni,V
A randomly diluted ferromagnet has its transition temperature Tc suppressed to a quantum critical point. Between the Tc of the diluted material and that of the undiluted... -
Investigation of Bose-Einstein condensation of magnons through temperature-fi...
YbAl3C3 exhibits a spin gap formation due to spin dimer ground state below 10 K. In zero-field the ground state is paramagnetic and no sign of long range magnetic ordering down... -
