Nanoparticle-enhanced Magnetic Field Induces Apoptosis in Nematode

Huang G.S., Yeh L.K., Chen Y-C, National Chiao Tung University, TW

To investigate molecular consequence of magnetic field to C. elegans, Fe3O4 nanoparticles were incorporated into the culture media of C. elegans and the nematodes were grown under magnetic field for 4 days. For the expermental [...]

The Study of the Nanocontact Imprint with Aminosilane

Shen F.Y., Chen J.H., Chen N.H., Lam K.Y., Chen J.H., Chen N.H., Huang F.S., National Tsing Hua University, TW

The purpose of this paper is to develop nano-contact imprint technology with simple process by using soft HSQ (hydrogen silsesquioxane) mold transfer aminosilane ink on HSQ and glass substrates with binding Glutraic dialdehyde (GA) and [...]

Chitosan Nanoparticle Combined with Ultrasound for Cervical Cancer Detection

Tsai K-C, Shieh M.J., Yang S.J., Lin W-L, Chen W-S, Institute of Biomedical Engineering, TW

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

Colorectal Cancer Cell Detection by Chitosan Nanoparticle Conjugated with Folic Acid

Yang S.J., Chen J-W, Shieh M.J., Institute of Biomedical Engineering, TW

Endoscopy is a common diagnosis device for the detection of colorectal cancer and there are two methods to improve the diagnostic sensitivity. One is chromoendoscopy, and the other is magnifying endoscopy. Color contrast dye, such [...]

Adsorption of Colloid Gold Nanoparticles on Charged Surface

Tzeng S-D, Luo C-S, Gwo S., Lin K.-J., National Chung Hsing University, TW

Colloid gold nanoparticles have many important applications, such as bio-molecular sensors and electronic devices. To fabricate the devices, one of the most significant processes is to assemble the gold nanoparticles on surface. In this work, [...]

Exact field enhancement factor, electrostatic force and field emission current from a long carbon nanotube

Zhbanov A.I., Pogorelov E.G., Chang Y-C, Academia Sinica, TW

We consider a field emitter on the base of carbon nanotube film consisting from randomly wreathed tubes. Under applied voltage some long ends of nanotubes laying on a surface of film should be straightened by [...]

Defect reduction of Multiwalled Carbon Nanotubes by Rapid Vacuum Arc Annealing

Tsai J.T.H., Li J.S., Tseng A.A., Tatung University, TW

A rapid thermal annealing process is demonstrated for defect reduction of multiwalled carbon nanotubes (MWCNTs) using a DC vacuum arc discharge system. The MWCNTs grown by chemical vapor deposition at a relatively low temperature (~650 [...]

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 [...]

Amorphous Diamond Solar Cells

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

Silicon based photo voltaic panels are the mainstream of solar cells. However, there are intrinsic limitations of such devices for replacing power plants. The low conversion efficiency (

Dye-sensitized solar cell using a TiO2 nanocrystalline film electrode prepared by solution combustion synthesis

Wang C.M., Chungb S.L., National Cheng Kung University, TW

The nanocrystalline anatase TiO2 films were prepared and characterized in connection with their application to dye-sensitized solar cells. Solution combustion synthesis of TiO2 nanocrystalline film is based on hydrolysis, nitrated, and combustion reaction. The solution [...]
