Cr-Kb X-ray Emission Spectra in Several Chromium Compounds (STATES AND STRUCTURES-Atomic and Molecular Physics)

Cr- Kb x-ray emission spectra in chromium metal and five chromium compounds were measured by using a double crystal spectrometer with high resolution. Differences in the appearance of Kb' and Kb" satellite lines are confirmed in the spectra of the compounds. The origin of Kb' and Kb" satellite lines is discussed due to both the number of unpaired electrons and the symmetry of ligands around the chromium atom

Detailed L Emission Spectra and Satellites of 74W (STATES AND STRUCTURES-Atomic and Molecular Physics)

The La and Lb spectra of tungsten were measured using a high resolution single crystal x-ray spectrometerand were fitted into Lorentzians. The fit residuals of the La and Lb spectra indicate satellites in the vicinity of each spectrum, which are originated from Coster-Kronig transitions. Linewidths, energies, and intensities were estimated for each diagram line

Synthesis of Lithium Manganate Powders by Spray Pyrolysis and its Application to Lithium Ion Batteries for Trams

Spinel type lithium manganate nanopowders were prepared by spray pyrolysis using metal nitrate solution. Chemical analysis and X-ray diffraction showed that homogeneous and high purity lithium manganate powders were obtained. The charge/discharge capacity of lithium manganate was 110mAh/g at 1C. A lithium ion battery module was also developed for the tram and its performance examined. The energy and power density of lithium ion cells were 110Wh/kg and 1920W/kg, respectively. The performance of a tram using a 20kWh type lithium ion battery module was examined. The tram ran for 20km on one charge
