The characteristics of double zincate pretreatment of thin Al films deposited on glass plates using magnetron sputtering and ion-beam sputtering were investigated.

4. Monitoring of Hydrogen Absorption into Titanium Using Resistometry - Azumi, Kazuhisa; Asada, Yoshihide; Ueno, Tomohiro; Seo, Masahiro; Mizuno, Tadahiko
Electric resistance of Ti increased with H absorption due to growth of a hydride layer from the surface toward the inside.

5. Direct Plating of Electroless Ni-P Layers on Sputter-Deposited Al-Ni Alloy Films - Azumi, Kazuhisa; Yugiri, Takuma; Kurihara, Toshiyuki; Seo, Masahiro; Habazaki, Hiroki; Fujimoto, Shinji
Direct plating of electroless Ni-P layers on Al-Ni alloy films formed on glass substrates was performed using magnetron-sputtered deposition and ion beam-assisted deposition methods.

6. Effect of Copper Pretreatment on the Double Zincate Process of Aluminum Alloy Films - Azumi, Kazuhisa; Egoshi, Shinnosuke; Kawashima, Satoshi; Koyama, Yuuichi
Etching pretreatment in H2SO4+CuSO4 solution was applied to magnetron sputter-deposited Al–Si alloy films formed on a glass plate to improve uniformity of Zn deposition in the double zincate process.

7. Selective optical probing of the charge-density-wave phases in NbSe3 - Shimatake, K.; Toda, Y.; Tanda, S.
A selective enhancement of the relaxation dynamics connected with one of the two charge-density-wave (CDW) phases was realized by tuning the probe energy to around 1.5 eV, in which the temperature dependence across the corresponding phase transition shows a pronounced anomaly.

8. High inoculation cell density could accelerate the differentiation of human bone marrow mesenchymal stem cells to chondrocyte cells. - Takagi, Mutsumi; Umetsu, Yousuke; Fujiwara, Masashi; Wakitani, Shigeyuki
The increase in the initial density of MSCs from 0.05×104 to 0.9×104 cells/cm2 accelerated the increase in the expression level of aggrecan mRNA during the differentiation culture for 7 d.

9. Ellipsometry of passive oxide films on nickel in acidic sulfate solution - Iida, Masahede; Ohtsuka, Toshiaki
and ??, during the anodic passivation and reduction, thickness of the passive oxide film was estimated with assumption of refractive index of nf = 2.3 of the film.
