Mesoscopic manganese based cathode materials for high voltage lithium ion batteries

Nam Hee Kwon

Alternative cathode materials were investigated for application to high voltage lithium ion batteries. Manganese based materials were considered due to the low cost and environmentally sustainable impact. Layer-structured oxide and phospho-olivine material ...

Self-assembly and dynamics of poly(γ-benzyl-L-glutamate) peptides

Harm-Anton Klok

The structure and the associated dynamics have been investigated in a series of oligopeptides of γ-benzyl-L-glutamate using DSC, WAXS, FTIR, NMR and dielectric spectroscopy, and rheology, respectively. The peptides with degrees of polymerization below 18 a ...

Cooperative Jahn-Teller distortion in PrO2

Philip Pattison

We report neutron diffraction data on single crystal PrO2 which reveal a cooperative Jahn-Teller distortion at TD=120±2 K. Below this temperature an internal distortion of the oxygen sublattice causes the unit cell of the crystallographic structure to beco ...

Specific heat capacity and Debye temperature of zirconia and its solid solution

Manuel Alexandre Pouchon

Specific heat CP of zirconia and yttria stabilized zirconia doped or not with erbia and ceria was measured from 128 to 823 K and of yttria stabilized zirconia doped with erbia and plutonia from 443 to 1573 K. The new determined data were modelled using Deb ...

ONLINE ENTHALPY MEASUREMENT METHOD FOR PHASE CHANGE SLURRIES

Didier Albert Simon Vuarnoz

To measure enthalpy densities, respectively overall specific heats, frequently the differential scanning thermal analysisis (DSC) is applied. Other useful methods are also available, but all of them have disadvantages. Therefore, an alternative measurement ...

Supercritical calorimetry: an emerging field

Thierry Meyer, Sophie Fortini, Frédéric Lavanchy

Calorimetry (adiabatic, isothermal, differential, oscillating or acoustic) is generally based on heat-flow measurements of the studied system. Most of its applications are dedicated to kinetic-parameter detn., safety studies and process optimization, phase ...

Micromachined infrared detectors based on pyroelectric thin films

Paul Muralt

The state of the art of thin-film pyroelectric infrared (IR) detectors is reviewed covering device physics, material performance, micro-fabrication and device examples. Emphasis is given to special issues related to thin films, such as small heat capacitie ...

Thermodynamic properties of carbonates at high pressures from vibrational modelling

Philippe Gillet

Simplified vibrational densities of states for five different carbonates are constructed using measured IR and Raman spectra. From the spectroscopic models we calculate thermodynamic and thermoelastic properties of magnesite, calcite, aragonite, dolomite, ...

HEAT TRANSFER OF ICE SLURRIES IN PIPES

Didier Albert Simon Vuarnoz

Some basic ideas of the heat transfer of ice slurries are discussed. The equations des-cribing a flow of a Bingham fluid through a tube with a heat flux over the boundary are presented. The theory shows that familiar Relations known in the field of heat ex ...

Determination of the thermal conductivity in zirconia based inert matrix nuclear fuel by oscillating differential scanning calorimetry and laser flash

Manuel Alexandre Pouchon

The performances of oscillating differential scanning calorimetry (ODSC) and laser-flash technique in determining the thermal conductivity and the specific heat of zirconia-based materials, analogous to a potential nuclear fuel, were compared. The tested m ...
