Polarized photoluminescence excitation spectroscopy of single-walled carbon nanotubes in VIS- UV range (2009)

Y. Miyauchi, S. Maruyama

Recently there has been considerable interest in the optical properties of single-walled carbon nanotubes (SWNTs) as one of the ideal quasi one-dimensional systems. Due to their one-dimensionality,...

Through fluorescence-spectrum measurements, we investigated the effects of light-assisted oxidation with H2O2 (LAOx) on single-wall carbon nanotubes (SWNTs) that were individually dispersed in an...

In-situ Raman diagnosis of laser-heated ACCVD growth process of (2008)

S. Chiashi, Y. Miyauchi, S. Maruyama, Shigeo Maruyama

We have built an atomic force microscope (AFM) with Raman scattering measurement capabilities and succeeded in synthesizing SWNTs on the AFM sample stage [1] using alcohol catalytic CVD method [2]....

Magnetic Brightening of Carbon Nanotube Photoluminescence through Symmetry Breaking (2007)

Shaver, J., Kono, J., Portugall, O., Krstic, V., Rikken, G. L. J. A., Miyauchi, Y., ...

Often a modification of microscopic symmetry in a system can result in a dramatic change in its macroscopic properties. Here we report that symmetry breaking by a tube-threading magnetic field can...

Magneto-optical (2006)

J. Shaver, J. Kono, O. Portugall, V. Krstic, G. L. J. A. Rikken, Y. Miyauchi, ...

Photoluminescence intermittency in an individual single-walled carbon nanotube at room temperature (2005)

Matsuda, K., Kanemitsu, Yoshihiko, Irie, K., Saiki, T., Someya, T., Miyauchi, Y., ...

We described the photoluminescence (PL) properties of individual micelle-encapsulated single-walled carbon nanotubes (SWNTs) at room temperature. Single PL peak from isolated individual SWNT with a...

Temporal and spatial dispersion of repolarization during premature impulse propagation in human intact ventricular muscle: Comparison between single vs double premature stimulation (2000)

Shimizu, S., Kobayashi, Y., Miyauchi, Y., Ohmura, K., Atarashi, H., Takano, T.

Aims This study was performed to determine whether or not the kinetics of action potential duration restitution during double premature stimuli (S3) differ from that during single premature stimuli...

Present status of the conceptual design of IFMIF target facility. (1998)

Temperature Dependence of Raman Scatterings from Single-Walled Carbon Nanotubes (1500)

S. Chiashi, Y. Miyauchi, Y. Murakami, S. Maruyama

Raman scatterings from various SWNT samples were measured at a wide range of temperatures (from 4 K to about 1000 K) in the vacuum environment [1]. With increase in sample temperature, both the Raman...

High-Mr glycoprotein profiles in human milk serum and fat-globule membrane.

Shimizu, M, Yamauchi, K, Miyauchi, Y, Sakurai, T, Tokugawa, K, McIlhinney, R A

Gradient-polyacrylamide-gel electrophoresis of human milk serum separated three high-Mr glycoprotein bands. The properties of the components corresponding to the three bands (tentatively termed...
