This research tends to propose an optimal executing order of developing policies in nanotechnology domain. By using the multi-objective compromise optimization method which integrating AHP with TOPSIS, we can conduct a priority of government policies [...]

Application of nanoparticle in photodynamic diagnosis for colorectal cancer

Yang S.J., Peng C.L., Lai P.S., Lin F.H., Shieh M.J., National Taiwan University, TW

Photodynamic medicine is a novel approach for cancer therapy and diagonosis via different photosensitizers and suitable light source. The 5-Aminolevulinic acid (5-ALA) can be converted into protoporphyrin IX (Pp IX ) that can be utilized [...]

Thermostability of TiO2 nanoparticle and its Photocatalytic Reactivity at Different Anatase/Rutile Ratio

Tseng Y-H, Lin H-Y, Kuo C-S, Li Y.Y., Lin H-Y, Huang C.P., Industrial Technology Research Institute, TW

Thermostability study of commercial P25 TiO2 nanoparticles was carried out by ascending annealing temperature from 400 to 1100 oC. The thermostability of TiO2 structure was measured by X-ray diffraction (XRD). Anatase-Rutile phase transition occurred only [...]

A New Copper Electrodeposition Scheme to Reduce Void Defects after Chemical Mechanical Polishing

Lin J.Y., Wang Y.Y., Wan C.C., Wang Y.Y., National Tsing Hua University, TW

Deposition of highly (111) oriented conductive layer is required for achieving better electromigration resistance and lower resistivity. Moreover, the amount of void defects decreases as the (111)/(200) ratio increases in CMP process. Hence, we investigated [...]

Feng H.P., Cheng M.Y., Wang Y.Y., Wan C.C., Wang Y.Y., National Tsing Hua University, TW

The behaviors of various electroplated copper films during CMP are important for removal mechanism and defect generation. This article was to study the characteristics of various copper films during CMP, including impurity effect and current [...]

Cold Cathode Fluorescence Light with Amorphous Diamond Coated Electrodes

Sung J.C., Kan M-C, Kinik Company, TW

Amorphous diamond is the only material that can emit electrons in vacuum when applied with an electrical field of only a few volts per micron and such current can increase hundreds or millions times when [...]

In Situ Synthesis of Carbon Nanotubes by Polymer Materials

Huang C.W., Hsu L.C., Li Y.Y., CCU, TW

Catalytically grown carbon nanotubes were prepared by in situ thermal decomposition of the polymer materials. Polymer material (PEG, polyethylene glycol) was employed as carbon source and nickel-based materials were used as catalytic precursors. These materials [...]

Investigation of Carbon Nanotube Mechanical Properties Using Atomistic-Continuum Mechanics Method

Wu C-J, Chou C.Y., Han C-N, Chiang K.N., Advanced Microsystem Packaging and Nano-Mechanics Research Laboratory, National Tsing Hua University, TW

This paper utilizes atomistic-continuum mechanics method (ACM) to investigate the mechanical properties of single-walled carbon nanotubes (SWCNTs). Fundamental to the proposed concept is the perception that a carbon nanotube is a geometrical frame-like structure, and [...]

Chang C-C, Chen C.C., National Chung Cheng University, TW

TiO2, CNT, coaxial composite array, visible-light absorption

Development of a 3-D Finite-element Solver for Piezoelectric Transformer Analysis

Chen Y-M, Lee C-K, Yang Y-J, National Taiwan University, TW

Piezoelectric transformers step up or step down input voltages by electrical/mechanical/electrical conversion. Piezoelectric transformers have been proved to be promising alternatives for magnetic transformers. Furthermore, since the fabrication technology of thin-film piezoelectric materials becomes mature, [...]
