TEM and ESCA Observations of Copper Deposits Containing Tin Impurities

Autor: Makoto Dobashi, Toshiko Yokota, Yoshihira Aoki, Noriko Hanzawa, Hiroyuki Kaneko

Publikováno v: Journal of the Surface Finishing Society of Japan. 49:519-524

TEM and ESCA observations have been used to study copper crystallite sizes, tin and oxygen atom concentration distributions, tin oxidation, and the crystal structure of tin oxide, compared to electrolytic polycrystalline copper deposits with no impur

Influence of Additives in Electrolytic Solution on Mass Change of Zinc Electrodeposited Films. Investigation by Quartz Crystal Microbalance Measurement

Autor: Toshiko Yokota, Takashi Shirakashi, Sachio Yoshihara, Makoto Dobashi

Publikováno v: Journal of the Surface Finishing Society of Japan. 48:330-336

Natural additive agents such as glue and gelatin have been used for preventing impurities from precipitating during deposition and for surface leveling of deposited films in the electrowinning industry. The mechanism behind the effect of their agents

Impurity Effect on Surface Morphologies and Mechanical Properties of Copper Deposits

Autor: Toshiko Yokota

Publikováno v: Journal of the Surface Finishing Society of Japan. 48:1109-1114

We studied how impurities-Cr, Fe, Co, Ni, Zn, Ag, Cd and Sn-in electrolytes, prepared with recycled copper, affect surface morphology and mechanical properties, i.e., tensile strength and elongation-of electrolytic polycrystalline copper deposlts, 35

Study on Zn Electrodeposition by Quartz Crystal Microbalance Method

Autor: Makoto Dobashi, Takashi Shirakashi, Naoki Takahashi, Sachio Yoshihara, Toshiko Yokota

Publikováno v: Journal of the Surface Finishing Society of Japan. 47:513-517

Natural additive agents in the electrodeposition process have long been used to improve deposition flatness and help prevent impurities from precipitating during deposition. The effective molecular weight and elements of these natural additives durin

ChemInform Abstract: Palladium- or Ruthenium-Catalyzed Synthesis of 2-Phenylindoles

Autor: Toshiko Yokota, Taeko Izumi

Publikováno v: ChemInform. 24

Allyl α-phenyl-2-aminophenethyl carbonates undergo a smooth decarboxylation-dehydrogenation reaction to afford 2-phenylindole derivatives in acetonitrile at 80 o in the presence of palladium complex as catalyst. In the reaction, the ruthenium hydrid
