Intense room-temperature photoluminescence of crystalline β-Ta2O5 nanobrick arrays

Ma Y-R, Lin J-H, Ho W-D, Devan R.S., National Dong-Hwa University, TW

In this study we analyzed the structural, electronic, and photoluminescence (PL) properties of a new morphological form, stacking Ta2O5 nanobrick arrays that were synthesized by hot filament metal-oxide vapor deposition. Field-emission scanning electron microscopy (FESEM) [...]

Channel-to-rib width ratio effects of flowfield plates in the performance of a micro-PEM fuel cell stack

Her B.-S., Hsieh S.-S., Chen J.H., National Sun Yat-Sen University, TW

Effect of channel-to-rib width ratio of flowfield plates on micro proton exchange membrane fuel cell stacks performance test (VI/PI) was studied experimentally in the present study (see Fig. 1). The channel-to-rib width ratio was varied [...]

Two-Phase Convective Heat Transfer in Microchannels

Lin C.Y., Hsieh S.-S., Chen J.H., National Sun Yat-Sen University, TW

Experiments were conducted to investigate subcooling flow boiling in 75 parallel microchannels (L=30 mm) having 200 μm (W) x 100 μm (H) cross-section with/without structured reentrant angle ( 0°、60°、90°and 120°). Boiling inceptions, flow morphologies, critical [...]

Parameterized Structural Capacitance Behavioral Modeling for TFT-LCD Panel

Huang H.M., Li Y., National Chiao Tung University, TW

Thin film transistors (TFTS) find wide usage in active matrix liquid crystal displays. The basic principle of operation of the LCD panel is to control the transparency of each pixel portion by bus lines to [...]

Gold nanoparticles caused learning impairment in mice

Chen Y-S, Hung Y.-C., Liau I., Lin L.-W., Hong M.-Y., Huang G.S., National Chiao Tung University, TW

Aims : To investigate the toxic effect of gold nanoparticles (GNP) to the learning and memory of mice. Key findings: Both 17 nm and 37 nm GNPs induced severe sickness in mice. However, only 17 [...]

Photothermal Characteristics study of PEGylated Gold Nanorods

Shih T-Y, Lin J-T., Tien C.C., Tseng P-L, Chen Y-H, Industrial Technology Research Institute, TW

Gold nanorods have a growing role in a diversity of medical applications especially in the area of hyperthermal therapy of tumor. Since localized temperature rising by laser irritation gold nanorods at near-IR frequency can induce [...]

A 3-dimensional nanobiosensor based on an anodic aluminum oxide template

Wang G.-J., Lin Y.-D., National Chung Hsing University, TW

In this paper, we propose a high sensitive nanobiosensor based on a 3D sensing element that has uniformly deposited gold nanoparticles. The sequential synthesis processes include: preparation of an AAO film; modification of the surface [...]

Ultrasensitive Protein Detection Using an Au/ZnO SPR-Based Biosensor

Chang C-C, Lin C-W, Lin S-H, Chiu N.-F., Lin C-W, Lin S-H, National Taiwan University, TW

In this study, we demonstrated that the Au/ZnO nanocomposite films could be effectively used to enhance the performance of SPR for the detection of tumor marker. Carbohydrate antigen 15.3 (CA15.3) tumor marker for breast cancer [...]

The Application of Ansperical Microlens Array on Direct Backlight System

Tsou C., Lai T., Huang C., Chang C., Wu C., Feng Chia University, TW

Today’s liquid crystal displays (LCDs) have to achieve more brightness and better uniformity in a thinner package, especially for the large-sized LCD panels with direct-type LED backlight system. Different reflective and transmissive characteristics managed by [...]
