Amorphous Diamond as a Thermionic Material

Sung J.C., Sung M., Kan M-C, Hsiao T-J., Chen Y-T, Sung J.C., Sung M., Kinik Company, TW

Amorphous diamond is essentially a chaotic carbon mixture with distorted sp2 and sp3 bonds. As such it possesses both metallic character of conductive graphite and semiconductor character of insulating diamond. Moreover, as each carbon atom [...]

Novel FD SOI Devices Structure for Low Standby Power Applications

Ma M-W, Chao T-S., Kao K-S, Huang J-S, Lei T-F, National Chiao Tung University, TW

In this paper, fully depleted (FD) SOI devices with S/D extension shift and high-k offset spacer were investigated in detail. The results show that the S/D extension shift can decrease Ioff significantly to reduce standby [...]

Assemblies of Blue-emitting CdSe Nanocrystals in Redox Copper Phenanthroline-based Polymeric Chains

Fu S.-J., Lin K.-J., National Chung Hsing University, TW

Assemblies of quantum-confined semiconductor nanoparticles into block copolymer micelles and silica shell open the door to “tunable” optical, electrical, and even mechanical properties. Sharp tuning of 3D spherical morphology in water solution is a fascinating [...]

Nanoimprint Mold Manufacturing with Focused Ion Beam

Chung M., Huang B.R., Weng M.H., Fu C.S., Chang Y.Y., Lai S.W., Chiou J.M., Chen Y-C, Tzeng Y.H., Southern Taiwan University of Technology, TW

Nanoimprint lithography (NIL) is an emerging low cost technique for reproducing sub-100 nm pattern in various applications; however, manufacturing the mold for nanoimprint has been a key issue both in expense and resolution. Focused Ion [...]

Poly(vinyl amine) Stabilized Colloidal CdS Quantum Dots of Color-Tunable Photoluminescence: Syntheses and Optical Properties

Chen K.M., Hou S.-S., National Cheng Kung University, TW

The colloidal CdS QD solutions were prepared with PVAm as the stabilizing polymer in a mixed solvent composed of methanol and water. The emitting colors of the prepared CdS QD colloids are tunable by varying [...]

Fabrication of CuO Nanofilm preparation by Electrophoretic Deposition

Chang H., Wei C.H., National Taipei University of Technology, TW

This paper uses electrophoretic deposition for coating a self-fabricated CuO nanofluid on a stainless steel substrate and measures the nature of this nanofilm. The pH value of the fabricated CuO nanofluid is 6.0, with a [...]

Prediction Model of Thermal Conductivity for Composite Materials with Nano Particles

Huang C-K, National Taipei University of Technology, TW

In this study, the transport theorem of phonons and electrons is utilized to create a model to predict the thermal conductivity of composite materials with nano particles. By observing or assuming the particle displacement in [...]

The Effects of Nano Particles on the Leidenfrost Phenomenon

Huang C-K, Lin C.K., National Taipei University of Technology, TW

When small amount of liquid mass is deposited on a hot enough solid surface, the liquid may not evaporate rapidly as we expect. Instead, the liquid mass evaporates slowly with a vapor film beneath. This [...]

A modified plasma arc gas condensation technique for the synthesis of tungsten oxide-based materials with various morphologies and structures

Su C.Y., LIn H.C., Yang Z.K., Lin C.K., National Taipei University of Technology, TW

Various nanoproducts including nanoparticles, nanorods, and nanowires have been prepared by a modified plasma arc gas condensation technique. By changing some parameters during the experiment, different kinds of products could be obtained. The results reveal [...]

A Novel Detection of Early Colorectal Cancer by Chitosan Nanoparticles Conjugated with Folic Acid

Yang S.J., Lin F.H., Tsai K-C, Shieh M.J., Institute of Biomedical Engineering, National Taiwan University, TW

The 5-Aminolevulinic acid (5-ALA) can be converted into protoporphyrin IX (PpIX) that can be utilized as a fluorescent probe for tumor detection. In this study, folic acid was conjugated on chitosan molecules via covalent bond [...]
