“…Such a behaviour is consistent with the network former character of Te and V [23]. However it may be interesting to mention that Rozier et al [15] have recently shown that an extra Li 2 O addition leads to an increase in conductivity because of the restitution of V in a higher coordination.…”

Structural and electrical properties of tellurovanadate glasses containing Li2O

Glassy materials are promising intercalation compounds, due to their open network structure and absence of grain boundaries. Some glasses containing alkali ions and a high concentration of transition metal ions can present mixed ionicelectronic conductivity and are therefore potential candidates for application as cathode material in Li-ion batteries. The present work is devoted to the ternary system x Li 2 O -(1-x) [0.3V 2 O 5 -0.7 TeO 2 ] with 0 ≤ x ≤ 0.4. These compounds were prepared by heat treatment in air at 800°C followed by traditional quenching. Raman spectroscopy and 51 V nuclear magnetic resonance measurements were performed in order to highlight the structural short range order modifications induced by the introduction of the Li 2 O network modifier. These structural effects can be related to the electrical behaviour, as studied by complex impedance spectroscopy measurements.

“…Earlier neutron scattering experiments [21,22] and Raman spectral studies [23,24] on TeO 2 glasses containing different modifiers have revealed that the basic building block of TeO 2 glass structure is a trigonal bipyramid commonly called TeO 4 E, where one of the three equatorial directions is occupied by the 5s 2 electronic pair (E) of the tellurium atom with two equatorial bonds. The three-dimensional close packing is constituted from vertices sharing TeO 4 groups (Te eq -O ax -Te) reinforced by weaker Te-O interactions [25,26].…”

Interplay between intramolecular and intermolecular structures of 1,1,2,2-tetrachloro-1,2-difluoroethane

We report on the interplay between the short-range order of molecules in the liquid phase of 1,1,2,2-tetrachloro-1,2-difluoroethane and the possible molecular conformations, trans and gauche. Two complementary approaches have been used to get a comprehensive picture: analysis of neutron-diffraction data by a Bayesian fit algorithm and a molecular dynamics simulation. The results of both show that the population of trans and gauche conformers in the liquid state can only correspond to the gauche conformer being more stable than the trans conformer. Distinct conformer geometries induce distinct molecular short-range orders around them, suggesting that a deep intra-and intermolecular interaction coupling is energetically favoring one of the conformers by reducing the total molecular free energy.
