SHINING THE BEAM ON BONES: CHARACTERISATION OF BURNED AND FOSSILISED SKELETAL...
Neutron spectroscopy is applied to study bones exposed to anaerobic burning or fossilisation. The results thus obtained will complement previous data gathered by the team on... -
The high-pressure structures of carbon dioxide hydrate
The gas hydrates offer potential as hydrogen and carbon dioxide storage materials for use either in transport applications or for carbon sequestration. We have discovered a... -
Metastable Water Ice and Nitric Acid ¿ observing the phase changes
The IPCC report 2007 underlines the particular importance of aerosol particles for the water cycle and the radiation balance, and thus for the global climate. In Cirrus clouds... -
Studying weakly hydrophobic guest hydrates and ammonia-water gas ternaries by...
The proposing team has a well established experience in the use of INS on samples containing molecular hydrogen. Our recent experimental results on various types of H2 clathrate... -
Continuation: Metastable Water Ice and Nitric Acid ¿ observing the phase changes
Nitric acid plays important roles in the atmosphere, in all aggregate states and combined with water.During the last periode we were running the proposal RB1110207 "Metastable... -
The proton momentum distribution in oriented ice films
We propose to fully characterise the proton quantum dynamics in oriented ice, grown on Pt surface, via DINS experiment and quantum ¿mechanical calculation, using path integral... -
Quasielastic scattering in stuffed spin ices: defects or low lying singlets?
The subjects of this proposal, Ho2+xTi2-xO7-x/2, are brand new materials1 related to Ho2Ti2O7, a spin ice2,3. They have the remarkable property of remaining disordered at very... -
Inelastic neutron scattering of deep glassy ice VI
Water displays a highly complex phase diagram that is key to a range of critical processes. Using ISIS facilities, our group has discovered three new phases of ice and most... -
Ice β-XV – a novel ice polymorph
Water molecules can form different hydrogen-bonded networks, a property known as ice polymorphism. So far 18 different networks have been characterized using neutron diffraction... -
Water proton's environment in Low Density and Very High Density Amorphous Ices
Amorphous polymorphism is one of the key concepts in our understanding of water, its structure, physical properties and anomalies. The basic idea is that liquid water at ambient... -
Magnetic Charge Transport in Spin Ice
The transport of electrically charged quasiparticles plays a pivotal role in modern technology. In contrast, the transport of magnetic charges has barely been explored... -
H_2 dynamics in filled ices prepared between 3 and 7 kbar
The proposing team has a well established experience in the use of INS on samples containing H_2. Our recent experimental results on sII and sH H_2-filled clathrate hydrates,... -
The unusually low zero-point energy of ice II: Critical benchmarking against ...
Water displays a highly complex phase diagram that is key to a range of critical processes. Using ISIS facilities, we have recently shown that ammonium-fluoride doping leads to... -
Dynamical Signatures of Quantum Spin Ice in Tb2Ti2O7
We propose the first neutron scattering experiment on the frustrated magnet Tb2Ti2O7 in the presence of a magnetic field along [111]. This will allow us to uncover signatures of... -
INS Determination of the Surface Properties of Nanoparticle Pollutants
Metal oxide nanoparticles are a form of pollution generated by a number of industrial procedures, and there is evidence that this class of nanoparticle can have a detrimental... -
Depth profiles of the contribution to total chlorophyll a+chlorophyllide a by...
Calculations were based on factors established for 89 water samples across Lake Baikal in July 2001 (see text). The traps were deployed for about 16 months and the core top... -
Relative percentage diatom profile for BAIK38 (BAIK94-38A), using uncorrected...
Fig. 3 is the diatom stratigraphy of dominant phytoplankton taxa for BAIK38 expressed as relative percentages, plotted against the age scale. Zone 1 (c. 880 AD–c. 1180 AD) is... -
Relative percentage diatom profile for BAIK94-38A using corrected values for ...
Preservation differences can be used as correction factors to recalculate the relative abundances of each of the five dominant plankton taxa in BAIK38 and are depicted in Fig.... -
Densities of benthic taxa with depth (CON 01-01 and CON 01-04 expeditions).
In all abyssal stations, densities are never over an average of c. 3100 individuals m−2 (Fig. 3, Table 1). In contrast, the shallow station (CON01-427, Posolskoe Bank) harbours... -
Depth profiles of marker pigments from Bacillariophyceae plus Chrysophyceae (...
The traps were deployed for about 16 months. The respective regression equations and its coefficients of determination (r2) are reported in Table 5.In the 40-m trap, fucoxanthin...
