Mechanical and Dielectric Properties of Polyhedral Oligomeric Silsesquioxanes Modified Graphene Oxide/Polyimide Nanocomposites

Ma C.-C.M., Liao W-H, Hsiao S-T, Wang Y-S, Li S-M, Liao W-H, Lin S-C, Lin S-C, National Tsing Hua University, TW

An effective method is proposed to prepare octa(aminophenyl) silsesquioxane (OAPS) functionalized graphene oxide (GO) reinforced polyimide (PI) composites with a low dielectric constant and ultra-high mechanical properties. The amine-functionalized surface of OAPS-GO is a versatile [...]

Ordered Structure Pattern on Polymeric Surface

Liu T.H., Huang C-L, Lee S., National Tsing Hua University, TW

The wrinkle pattern on polymeric surface is explained by chemical stresses. We solved the anomalous transport equation to obtain the concentration of solvent in polymeric film. The anomalous transport consists of case I and case [...]

Tunable-Linewidth Nanoimprint Working Stamps Fabricated by Double Oblique Metal Deposition

Lin C.H., Wu C-L, Sung C.K., National Tsing Hua University, TW

This paper proposes a low cost but rapid methodology for fabricating working stamps with tunable line-width or pitch structures. Conventionally, the master stamp for nanoimprint lithograph (NIL) is made of silicon by e-beam lithography, which [...]

Chemical Fluid Deposition of Ru/MCM-41 as Catalyst for Hydrogenation in Green Environments

Lin H.W., Yen C.H., Tan C.S., National Tsing Hua University, TW

The Ru/MCM-41 catalyst prepared by chemical fluid deposition technique exhibited high catalytic activity for hydrogenation of p-xylene, bisphenol A, bisphenol F and benzoic acid, which was higher than that of a conventionally prepared Ru/MCM-41 catalyst. [...]

The Effect of Growth Temperature on Aluminum Nanocrystal Embedded AlOxNy for Non-Volatile Memory

Chen N.H., Hsieh P-H, Huang F.S., Huang S-J, Huang F.S., Huang S-J, National Tsing Hua University, TW

The aim of this paper is to present a aluminum-based nonvolatile memory of Al2O3 (28 nm)/ Al-rich Al0.54O0.42N0.04 (22 nm)/ Al0.44O0.38N0.18 (3 nm) layered structure on SiO2 (2 nm)/ n-Si by a simple rapid thermal [...]

Fabrication of PEG Hydrogel Microstructures in Microfluidic System for Multicellular Spheroid Formation, Culturing and Analysis

Fu C.-Y., Chang H.-Y., National Tsing Hua University, TW

In this abstract, we describe a novel PEG-based, simple-to-fabricate, U-shaped micro-scale growth chamber, which allows cell trapping and forming into spheroids as well as culturing in the presence of a continuous perfusion flow, a long-term [...]

Fabrication of Magnetic Poly (ethylene glycol) Hydrogels Blocks Using Microfluidic System for Cell Patterning Techniques

Chang H.-Y., Fu C.-Y., Lin C.Y., Wang T.-P., National Tsing Hua University, TW

In this study, we developed a novel technique called magnetic hydrogel-based cell patterning (MHCP) to easily achieve heterotypic cell patterning in both of multi-well plate-based methods and microfluidic system. We also demonstrated that the material [...]

Cytotoxicity Assessment of Human Lung Alveolar Cell Exposed to Nanoparticles and Polycyclic Aromatic Hydrocarbons Exhausted from Motorcycle

Chien S.M., Huang Y-J, Chuang C.C.Y., Hsiao I.L., Kuo Y.F., National Tsing Hua University, TW

The potential harmfulness of traffic pollutants, particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs), were elevated with the increment of motocycles. However, the toxicology of the nanoparticulate and particle-PAHs (p-PAHs) has rarely been evaluated in [...]

Comparing Cytotoxicity of ZnO Nanoparticles in Exposure to Serum/Serum-free Cell Culture Medium

Hsiao I.L., Huang Y-J, National Tsing Hua University, TW

The aim of this study is to evaluate the influence of serum in cell culture medium on nanotoxicity to human lung epithelial cells (A549). We found nano-ZnO had greater toxicity as it was suspended by [...]

Post-annealing effect of copper phthalocyanine on enhancing the performance of green organic light-emitting diode

Chen S.Z., Jou J.H., Tang F.S., Chiang P.H., Chang C.Y., National Tsing Hua University, TW

Post-annealing copper phthalocyanine (CuPc) can effectively improve the efficiency of a green organic light-emitting diode, consisting of indium tin oxide/CuPc/N,N’-bis-(1-naphthyl)- N,N’-diphenyl-1,10-biphenyl-4-4’-diamine/tris-8-hydroxy-quinoline aluminum/lithium fluoride /aluminum. By annealing the device at 120℃ for 1 hr, the power [...]
