Effects of _-Stabilized Alloying Element on the Nanotube Morphology of Ti-Alloy

Jang S.H., Choe H.C., Ko Y.M., Brantley W., Chosun University, KR

In the present study, we chose Nb as a binary alloying element because it has excellent biocompatibility and be expected to act as a -stabilizer. The purities of the starting raw materials were 99.99% for [...]

Electrochemical Characteristics of Nanotube Formed Ti-Zr Alloy

Kim W.G., Choe H.C., Ko Y.M., Brantley W., Chosun University, KR

In this paper, Ti-Zr(10, 20, 30 and 40 wt%) alloys were prepared by arc melting and nano-structure controlled for 24 hr at 1000 °C in argon atmosphere. Formation of oxide nanotubes are conducted by anodizing [...]

Phenomena of Nanotube Formation on the Surface of Cp-Ti, Ti-6Al-4V, and Ti-Ta alloys

Lee K., Choe H.C., Ko Y.M., Brantley W.A., Chosun University, KR

In this study, the phenomena of nanotube formation on the surface of Ti alloys by electrochemical method. Nanotube layer formed on Ti alloys in 1 M H3PO4 and 1 M H2SO4 electrolyte with small additions [...]

Nanotube Formation and Surface Study of New Ternary Titanium Alloys

Choe H.C., Ko Y.M., Brantley W.A., Chosun University, KR

New titanium alloys with improved biocompatibility have been developed for dental and biomedical applications. The osseointegration of implants depends on surface properties of these alloys; nature of the oxide film at the metal-oxide-bone. Also stress [...]

Solubilization of Capsaicin and Its Nanoemulsion Formation in the Sonication and Self-Assembly Processes

Choi A.J., Kim C.J., Kim C.T., Cho Y-J, Choi A.J., Hwang J.K., Kim C.J., Kim C.T., Korea Food Research Institute, KR

Currently, interests in food nanotechnology and its research and development are at an initial stage in the world, and food industry is slowly moving to embrace it and preparing for establishment of a final goal [...]

Molecular Dynamics of Self-Assembled Monolayer Formation in Soft Nanolithgoraphy

Heo D., Yang M., Jang J., Pusan National University, KR

Molecular dynamics simulation is performed to study the growth mechanism of self-assembled monolayer in the AFM tip-assisted soft nanolithography such as in dip-pen nanolithography [1]. We investigate how the droplet created around the tip spreads [...]

Mechanical and Electrical Properties of CNT/Inorganic Nanocomposites by Molecular Level Mixing Process

Hong S.H., Korea Advanced Institute of Science and Technology, KR

One of the emerging applications of CNTs is the reinforcement of composite materials to overcome the performance limits of conventional materials. However, because of the difficulties in distributing CNTs homogeneously in metal or ceramic matrix [...]

Numerical Stress Analysis on Thermal Nano-Imprint Lithography

Cho B-G, Park S.Y., Won T., Inha University, KR

This paper investigations the stress distribution of the polymer through numerical simulations during thermal NIL. Numerical results explained characteristic phenomena which never appear in continuous line-and-space patterning cases. We believe that numerical simulations with more [...]

Ab-initio Calculations of Uniaxially and Biaxially Tensile Stress Effect

Kim Y.K., Park S.Y., Won T., Inha University, KR

In this paper, we present an ab-initio study on energy configurations, minimum energy path (MEP), and migra-tion energy for neutral indium diffusion in a uniaxial and biaxial tensile strained {100} silicon layer for the first [...]

Alcohol vapor sensors using multiple spray-coated SWCNTs

Kim S.J., Choi Y.M., Lee G.W., Kyungnam University, KR

Recent advances in purification, dissolution and dispersion technologies of carbon nanotubes (CNTs) have provided opportunities for the development of various CNT gas sensors[1-2]. Here, we suggest an alcohol vapor sensor using single-walled carbon nanotube (SWCNT)-composites [...]
