Surface characterization of Cu-M (M=Ti, Zr, or Hf) alloy powder catalysts
Article Abstract:
A study was conducted to characterize amorphous Cu-M alloy powders generated by the mechanical alloying of the constituents using X-ray photoelectron spectroscopy. The Kratos XSAM 800 spectrometer was utilized to obtain the XP spectra while the Cu(super 0) surface area of the catalysts was determined by N2O titration based on the reaction of nitrous oxide with Cu(super 0) species. Results indicated that instrumental studies and copper surface area measurements supported the characterization of the surface structural and compositional changes associated with Cu-M amorphous alloy powders.

Structure of liquid Al2O3 from a computer simulation model
Article Abstract:
A study on diffraction experiments on ionic systems in both the crystalline and liquid states demonstrates how the combination of new containerless sample and high intensity synchrotron source technologies enables the x-ray diffraction pattern from a molten oxide, Al2O3, to be determined for the first time. The method presented is a simplified version of one which correctly predicts the ground state crystal structure of Al2O3. Further, Al2O3 is a good candidate for studying the phenomenon of polyamorphism in the liquid state.

Preparation of fast lithium ion conducting glasses in the system Li2S-SiS2-Li3N
Article Abstract:
A study on lithium ion secondary batteries reports on the preparation and the thermal, electrical and electrochemical properties of Li2S-SiS2-Li3N glasses. Melt-quenching under vacuum was used to produce (60-3x/2)Li2S.40SiS2.xLi3N (where x is less than or equal to five). Both temperatures of glass transition and crystallization increased with an increase in nitrogen content. The glasses' main charge carrier was the lithium ion and they exhibited high electrochemical stability in a wide potential range of 10 V.
