Nano-carbon materials are promising canidates for applications in high performance devices, including highly sensitive biosensors. We have developed a self-alignment process for nano-carbon field effect transistors (FETs), using a carbon nanowall (CNW)—a nano-carbon materials—to fabricate CNW-FETs. We measured the pH dependence of the device properties. The binding molecules are known to be key...

Nano-plasticity of thin single-wall carbon nanotubes under uniaxial compression is investigated through generalized tight-binding molecular dynamics (GTBMD) and ab-initio electronic structure methods. A novel mechanism of nano-plasticity of carbon nanotubes under uniaxial compression is observed in which bonding geometry collapses from a graphitic (sp 2) to a localized diamond like (sp 3) recon...

We describe the nanofabrication study of self-aligned electrodes on suspended multiwalled carbon nanotube structures. When metal is deposited on a suspended multiwalled carbon nanotube structure, the nanotube acts as an evaporation mask, resulting in the formation of discontinuous electrodes. The metal deposits on the nanotubes are removed with lift-off. Using Al sacrificial layers, it was poss...

[Abstract] In order to fabricate new dye-sensitised solar cell, we proposed a new photoresponsive electrode structure using bio nano process. Carbon nanotube-TiO2 hybrid materials having multitudious nano-sclae cavities were realized using a bifunctional cage-shaped protein possessing carbonaceous material-binding peptides and Ti-binding peptides. The obtained structure was confirmed to consist...

Nano-carbon as lighting source is demonstrated in this paper. The characterized nano-radiation from nano-carbon, excited by different lasers in vacuum, is observed when laser intensity is over a threshold. With lower excitation threshold and smaller white light source, nano-carbon is more applicable to be as lighting system than the others in scientific experiments. White light emission of nano...

A multi-scale investigation of nanostructured carbon films has been performed by means of inelastic light scattering (Raman and Brillouin scattering). Carbon films with different nanoand mesostructure have been deposited from supersonic cluster beams in a low energy deposition regime by exploiting aerodynamic focusing effects. Acoustic phonon propagation in the porous amorphous structure, where...

Lamellar hard carbon derived from holly leaf with enlarged pores of tiny graphite-like domains and meso-pores was prepared by hydrothermal followed high temperature pyrolysis process. Benefiting from the enlarged nano-pores of tiny graphite-like domains and the thin sheet structure with meso-pores, the derived carbon delivered a high reversible capacity of 318 mAh g(-1) at a current rate of 20 ...

Top-down approach for vertically aligned CNWs has not reported yet although it is necessary for immediate integration of CNWs with micro and nano systems. In this paper, vertically aligned pyrolyzed carbon nanowires (CNWs) is fabricated by photolithography with modification and pyrolysis as a top-down approach which the control of shape and position of CNWs is reliable. Subμm high aspect ratio ...

Nano carbon materials as nanotube and fullerene have a potential for applications to the advanced industries. For nano carbon materials, it has been recognized that large-scale simulation is a powerful and efficient tool to find and create new functional nano carbon materials. Aiming at conducting the productive simulation for nano-materials, we have developed the large-scale simulation models ...

Objective and Background: Fluoride is an element widely found in the earth crust. Advantages and disadvantages of fluoride in the human body are depended on its concentration. Long-term consumption of drinking water contaminated with arsenic can cause adverse health effects such as skin lesions and cancer in humans. The aim of this study was to study efficiency of nano alumina on multi walled c...
