A new Li-Al-N-H system for reversible hydrogen storage

Article Abstract:

The dehydrogenation/rehydrogenation reactions of a combined system of Li3AlH6 and LiNH2 are investigated. The results reveal that the dehydrogenation reaction of the new material system is nearly 100% reversible and a short-cycle experiment has shown that the new combined material system of alanates and amides could maintain its hydrogen storage capacity upon cycling of the dehydrogenation/rehydrogenation reactions.

Dispersion and reduction of copper oxide supported on WO3-modified Ce0.5Zr0.5O2 solid solution

Article Abstract:

The various methods, which includes X-ray diffraction, and laser Raman spectra are used to investigate the surface properties of copper oxide/WO3/Ce0.5Zr0.5O2 samples. The results indicate the effect of the loading amount of WO3 on the reduction property of Cu(super 2+) ions in a series of CuO/WO3/CZ samples.

Size-distribution and emission spectroscopy of W nanoparticles generated by laser-assisted CVD for different WF6/H2/Ar mixtures

Article Abstract:

Tungsten nanoparticles were produced by ArF excimer laser-assisted chemical vapor deposition from WF6/H2/Ar gas mixtures. X-ray fluorescence spectroscopy determined rate of W nanoparticle films deposition.
