Synthesizing Cubic Diamond Crystal Using DC Plasma Jet CVD
Autor: Xia Zhu, Ryoya Shiraishi, Hiromichi Toyota, Kazuto Nakajima, Shinfuku Nomura, Yukiharu Iwamoto
Publikováno v: Key Engineering Materials. 825:71-76
Diamond crystals are successfully synthesized by irradiating DC arc plasma jet to the substrate set in a methanol solution. It is the important procedure to preheat the substrate by inert Ar plasma jet before introducing the methanol solution gas to

Effect of Amorphous Silicon Carbide Interlayer on Diamond-Like Carbon Film Structure and Film Hardness
Autor: Yukiharu Iwamoto, Hiromichi Toyota, Yutaroh Kimura, Ryoya Shiraishi, Shinfuku Nomura, Xia Zhu
Publikováno v: Key Engineering Materials. 825:99-105
This study was performed to improve the adhesiveness of a diamond-like carbon (DLC, a-C:H) layer film with an a-SiC interlayer. In previous studies, an a-SiC/DLC layer film was formed and changes in the DLC film structure and hardness caused by the t

Simultaneous Synthesis of Diamond and Hydrogen
Autor: Shinfuku Nomura, Hiromichi Toyota, Yukiharu Iwamoto, Kazuto Nakajima, Ryoya Shiraishi, Xia Zhu
Publikováno v: Key Engineering Materials. 825:77-83
A relationship between diamond synthesis and hydrogen production in in-liquid plasma method have been investigated. Approximately 60 % energy can be recovered by collecting hydrogen gas made by ingredient solution decomposition. The relationship is t

Effect of introducing a steam pipe to n-dodecane decomposition by in-liquid plasma for hydrogen production
Autor: Ryoya Shiraishi, Hiromichi Toyota, Shinobu Mukasa, Shinfuku Nomura, Yuki Amano
Publikováno v: International Journal of Hydrogen Energy. 44:16248-16256
A method has been developed to improve the hydrogen production efficiency (HPE) by in-liquid plasma n-dodecane decomposition. A thin steam pipe is placed over the plasma electrode to recover the thermal energy emitted from the plasma to its surroundi
