Study of thermal stability for tertiary pyridine ion exchange resin and anti-corrosion property of structural material toward eluents used in the advanced ORIENT cycle process

Autor: K. Kurosawa, K. Tatenuma, Ken Okada, Yoshihiko Sato, Shin-ichi Koyama, Masaki Ozawa

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 286:807-813

A multi-functional separation process is pro- posed as one of the technologies for implementing the Adv.-ORIENT (Advanced Optimization by Recycling Instructive ElemeNTs) Cycle concept (1). The tertiary pyridine-type anion exchange resin (TPR) embedde

Fundamental functions of a new type of leak detector using oxygen-ion conductor

Autor: Takashi Momose, K. Tatenuma, H. Saeki, A. Ando, K. Uchida, T. Noguchi

Publikováno v: Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films. 18:1755-1757

A new type of leak detector (LeakD) was developed using the principle of selective and sensitive oxygen detection using oxygen-ion-conducting ceramics, e.g., yttria-stabilized zirconia (YSZ). By comparing the experimental results of the LeakD with a

Surface cleaning on aluminum for ultrahigh vacuum using supercritical fluid CO2 with H2O and NaCl as additives

Autor: Z. Sherverni, Takeo Ebina, H. Yoshida, K. Tatenuma, Takashi Momose, Yutaka Ikushima

Publikováno v: Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films. 17:1391-1393

Ozone treatments have been shown to reduce the outgassing rates in ultrahigh vacuum for several metals. We have further studied surface cleaning employing supercritical fluid CO2 which has high solubility for hydrocarbons. The sample measured was a h

Ultrahigh electron emissive carbon nanotubes impregnated with subnano RuO/sub 2/ clusters

Autor: T. Fukuda, Fumihito Arai, Y. Saito, S. Kato, H. Muto, Tsuneyuki Noguchi, K. Tatenuma, Pou Liu, E. Yashima

Publikováno v: 5th IEEE Conference on Nanotechnology, 2005..

Multi-wall carbon nanotubes (MWNTs) have a great commercial potential as electron field emitters but suffer from fundamental problems such as poor stability and lack of brightness. Here we show that the MWNTs impregnated with nano and subnano-sized r
