“…Data were collected at a scattering angle of 2θ from 2° to 82° with 0.05° step size and 10°/min scan speed (BRUKER AXS D2 phaser, Karlsruhe, Germany). 2θ for equivalent CuKα radiation was calculated using Bragg's Law [94].…”

“…The chemical quantification was calculated using the Cliff-Lorimer (or ratio) method, which is considered a good approximation for thin films. 25 Elemental maps via EFTEM were acquired using a contrast aperture of about 10 mrad to reduce aberrations, mostly chromatic, and using the three windows method. 26 The elastic image (or zero-loss image) was acquired as a reference with a 10 eV wide energy slit; then, chemical maps using the S L-edge (165 eV), Cd M-edge (404 eV), Cu L-edge (931 eV) and Se L-edge (1436 eV) were acquired on the same area of zero-loss with energy slits of 20 eV, 30 eV, 50 eV and 60 eV, respectively.…”

Cubic and hexagonal phase Cu 2-x (S y Se 1-y ) alloy nanocrystals, with a well-defi ned near-infrared valence band plasmon resonance, were transformed in the corresponding Cd-based alloy nanocrystals, with the comparable S y Se 1-y stoichiometry, by cation exchange preserving the original crystal structure. Cubic Cu 2-x (S 0.5 Se 0.5 ) nanocrystals were then evaluated as anode material in Li-ion batteries. As featured in:See E. Dilena et al., J. Mater. Chem., 2012, 22 We report synthetic routes to both cubic and hexagonal phase Cu 2Àx (S y Se 1Ày ) alloy nanocrystals exhibiting a well-defined near-infrared valence band plasmon resonance, the spectral position of which is dependent mainly on x, i.e. on Cu stoichiometry, and to a lesser extent on the crystal phase of the NCs. For cubic Cu 2Àx (S y Se 1Ày ) nanocrystals y could be varied in the 0.4-0.6 range, while for hexagonal nanocrystals y could be varied in the 0.3-0.7 range. Furthermore, the Cu 2Àx (S y Se 1Ày ) nanocrystals could be transformed into the corresponding Cd-based alloy nanocrystals with comparable S y Se 1Ày stoichiometry, by cation exchange. The crystal phase of the resulting Cd(S y Se 1Ày ) nanocrystals was either cubic or hexagonal, depending on the phase of the starting nanocrystals. One sample of cubic Cu 2Àx (S y Se 1Ày ) nanocrystals, with S 0.5 Se 0.5 chalcogenide stoichiometry, was then evaluated as the anode material in Li-ion batteries. The nanocrystals were capable of undergoing lithiation/delithiation via a displacement/conversion reaction (Cu to Li and vice versa) in a partially reversible manner.

“…1. Using Nelson-Riley plots, 33 the lattice parameter a was found at all measured temperatures. These are listed in Table I and agree with values of the lattice parameter calculated using the accepted temperaturedependent linear coefficient of thermal expansion 34 and room temperature-lattice parameter.…”

Neutron scattering measurements of phonons in nickel at elevated temperatures

Measurements of elastic and inelastic neutron scatterings from elemental nickel were made at 10, 300, 575, 875, and 1275 K. The phonon densities of states ͑DOSs͒ were calculated from the inelastic scattering and were fit with Born-von Kármán models of the lattice dynamics. With ancillary data on thermal expansion and elastic moduli, we found a small, negative anharmonic contribution to the phonon entropy at high temperature. We used this to place bounds on the magnetic entropy of nickel. A significant broadening of the phonon DOS at elevated temperatures, another indication of anharmonicity, was also measured and quantified.
