Effect of pulse current on structure and adhesion of apatite electrochemically deposited onto titanium substrates (2008)

Hayakawa, Tomoyasu, Kawashita, Masakazu, Takaoka, Gikan H., Miyazaki, Toshiki

Apatite films were deposited onto titanium (Ti) metal substrates by an electrodeposition method under a pulse current. Metastable calcium phosphate solution was used as the electrolyte. The ion...

Dependence of size distribution for liquid cluster ions on retarding voltage (2008)

Takaoka, Gikan H., Okada, Takeshi, Sugiyama, Kazumichi, Kawashita, Masakazu

We have succeeded in producing liquid clusters such as ethanol and water clusters by an adiabatic expansion phenomenon, and the cluster size distribution was analyzed by using the time-of-flight...
