Synthesis of the string-like CNT having few layers stacking of graphene

Muramatsu K., Toyoda M., Incubation　Alliance,Inc., JP

In this study and development,it challenged in synthesizing of flexible CNT having few layers graphene and showing the excellent physical property different from graphite fibers. In this study,raw material calcined and cobalt acetylacetonato were mixed [...]

Generation and Evaliation of Graphene Depends on the Electron Irradiation Applied to the Fullerene

Matsukawa S., Kubota H., Kumamoto University, JP

Graphene is a flat monolayer of carbon atoms tightly packed into a two-dimensional (2D) honeycomb lattice, and is a basic building block for graphitic materials of all other dimensionalities. Electrons of graphene behave as Dirac [...]

Spectroscopic study on the charge redistribution between Au and Ag in Au@Ag core-shell nanoparticles

Nishimura S., Anh D.T.N., Mott D., Ebitani K., Maenosono S., Japan Advanced Institute of Science and Technology, JP

Charge transfer in heteromeric structures such as Au@Ag core-shell nanoparticles (NPs) and Au@Ag@Au double-shell NPs was demonstrated using X-ray absorption near-edge structure (XANES) and X-ray photoelectron spectroscopy (XPS) techniques. XANES analyses confirmed that the d-orbital [...]

A Helical Peptide can Mediate Electron over 120 Å by Hopping Mechanism

Arikuma Y., Nakayama H., Morita T., Kimura S., Kyoto University, JP

We have studied long-range electron transfer through various lengths of helical peptides from 8 mer (24 Å) up to 80 mer (120 Å) in self-assembled monolayers prepared on a gold surface. Helical peptides carrying a [...]

Platinum Bowtie Nanostructure Arrays for Massively Parallel Single Molecule Detection Based on Fluorescence Enhancement Phenomena

Saito T., Takahashi S., Obara T., Itabashi N., Imai K., Hitachi High-Technologies Corporation, JP

To enable not only long sequence read but also high throughput in a DNA sequencer, the single molecule sequencing method based on direct observation of processive DNA polymerization is very promising. In this method, only [...]

Modeling of the impurity-gradient effect in high-voltage MOSFETs

Maekawa Y., Fukushima K., Tanaka A., Kikuchihara H., Miyake M., Mattausch H.J., Miura-Mattausch M., Miura-Mattausch M., Hiroshima University, JP

Two major high-voltage MOSFET types are commonly used by semiconductor industries. One has a symmetrical structure, and the other has a laterally-diffused asymmetric structure called LDMOS. Here our focus is the LDMOS structure, where an [...]
