We studied the dynamics of photoluminescence (PL) and energy transfer in close-packed monolayer films of CdSe and Au nanoparticles (NPs) assembled using the Langmuir-Blodgett technique. The PL...
Analysis of Gasses Generated by Electrical Discharges in Low Viscosity Silicone Oil (2008)
Endo, Fumihiro, Yamamoto, Shinpei, Sadakane, Takayuki, Yamagishi, Akira, Miyagi, Katsunori, Okubo, Hitoshi
Silicone oil has merits of less flammability and excellent environment-friendliness. High-viscosity silicone oil of 50 cSt has been widely applied to power and distribution transformers. Recently,...

Chemical groups that adhere to the surfaces of living malignant cells (2007)
McNamee, Cathy E., Aso, Yuki, Yamamoto, Shinpei, Fukumori, Yoshinobu, Ichikawa, Hideki, Higashitani, Ko
Yamamoto, Shinpei, Morimoto, Yasumasa, Tamada, Yoshinari, Takahashi, Y. K., Hono, K., Ono, Teruo, ...
A method to prepare monodisperse and highly coercive L10-FePt nanoparticles which are dispersible in nonpolar organic solvents such as toluene, chloroform, and hexane was developed. By vigorously...
Tamada, Yoshinori, Morimoto, Yasumasa, Yamamoto, Shinpei, Hayashi, Naoaki, Takano, Mikio, Nasu, Saburou, ...
We investigated magnetic properties of the L10-FePt nanoparticles synthesized by the SiO2-nanoreactor method by means of Moessbauer spectroscopy from the microscopic point of view. Almost all of the...
Magnetically Superior and Easy to Handle L10-FePt Nanocrystals (2005)
Yamamoto, Shinpei, Morimoto, Yasumasa, Ono, Teruo, Takano, Mikio
We report a successful synthesis of monodisperse L10-FePt nanocrystals which are not only superior in magnetism but also easy to handle through being dispersible in solvents. Thanks to a thick...

Direct force measurements were made by atomic force microscopy (AFM) at surfaces of polymer brushes comprising low-polydispersity poly(methyl methacrylate) chains densely end-grafted on a silicon...
Optimization for β-Mannanase Production of a Psychrophilic Bacteriunm, Flavobacterium sp. (1998)
Zakaria, Mia Md., Ashiuchi, Makoto, Yamamoto, Shinpei, Yagi, Toshiharu
Ejaz, Muhammad, Yamamoto, Shinpei, Ohno, Kohji, Tsujii, Yoshinobu, Fukuda, Takeshi, Miyamoto, Takeaki
The atom transfer radical polymerization technique using the copper/ligand complexes was applied to the graft polymerization of methyl methacrylate on the Si wafer on which the monolayer of the...
Active Transport Activities of Free B-6 Vitamers in Various Yeast Strains (1996)

Purification and Characterization of Aspartate Aminotransferase Isoenzymes from Rice Bran (1993)
Yagi, Toshiharu, Sako, Masayuki, Moriuti, Shinya, Shounaka, Masafumi, Masaki, Kazunari, Yamamoto, Shinpei
Yagi, Toshiharu, Shounaka, Masafumi, Yamamoto, Shinpei
The distribution of aspartate aminotransferase activity in yeasts was determined. The number of species of the enzyme in each yeast was determined by zymogram analysis. All the yeasts, except for the...

Effect of the Physicochemical Properties of Poly(Ethylene Glycol) Brushes on their Binding to Cells
McNamee, Cathy E., Yamamoto, Shinpei, Higashitani, Ko
We investigated the effect of the number of oxyethylene groups (polymer molecular weight) and the interchain binding and/or entanglements of methoxy-terminated-poly(ethylene glycol) (m-PEG) brushes...
