Photocatalytic disinfection of E. coli using tourmaline-N-doped TiO2 composite

Tzeng J-H, Lin Y.-T., Weng C-H, National Chung Hsing University, TW

Neither the microbicidal mechanism of TiO2 under visible radiations nor their potential effects in the light intensity have yet been well established. In this paper, the photocatalytic inactivation of bacteria was investigated using E. coli, [...]

Adsorption of Tetramethylammonium Hydroxide (TMAH) on Y-type Zeolite

Chang S., Lu C., National Chung Hsing University, TW

Y-type zeolite have high TMAH removal efficiency when pH>4 with solid-liquid ratio (S/L) of 2 g/L in 20 minutes. The correlation coefficients of Langmuir and Freundlich isotherm models are 0.973 and 0.997, respectively. The exponential [...]

Mn-Zn Ferrite and Photosensitizer Co-Loaded Cancer Theranostic Agent for Magnetic Resonance Imaging and Photodynamic Therapy

Lai P.S., Lai S.M., Yang M.-D., Tung M.-J., Lai P.S., Lai S.M., National Chung Hsing University, TW

Developing a nanodevice with simultaneous cancer imaging and therapy is one of the promising approaches for cancer treatments. In this report, a multifunctional cancer theranostic system based on magnetic resonance (MR) contrast agent and photosensitizer [...]

Clusters of Iron Oxide Nanoparticles for Efficient Magnetic Resonance Imaging

Lai P.S., Lai S.M., Lai P.S., Lai S.M., National Chung Hsing University, TW

Recently, self-assembling clusters of metal nanoparticles have been extensively investigated in various fields. To prepare these clusters, various ionic surfactants, have been employed as stabilizers or emulsifiers to form water-dispersed spherical clusters. However, these ionic [...]

Electronic Structure and Band Gap Engineering of ZnO-based Semiconductor Alloy Films

Liu P-L, Shao P-T, National Chung Hsing University, TW

We conduct first-principles total-energy density functional calculations to study the band structures and atomic structures in ZnO and Zn0.5M0.5O alloys using the planewave projector augmented-wave (PAW) method with the Heyd-Scuseria-Ernzerhof (HSE) hybrid functional. We find [...]

Photocurable Composite with Antimicrobial Activity for Wound-Healing

Chang M-H, Ding F.-C., Ju W.-Y., Lai P.S., National Chung Hsing University, TW

To develop an appropriate approach that can accelerate the wound healing rate or prevent other microorganisms contamination is necessary for wound healing. In this study, the combination of antimicrobial activity and photodynamic antimicrobial chemotherapy of [...]

Overcome the Doxorubicin Resistance by Multimodal Nanoparticles in Mice

Lai P.S., Hsu C.Y., Lu H.-L., Yu H.-P., Syu W.-J., Shieh M.J., National Chung Hsing University, TW

The efficacy of many chemotherapeutic agents is reduced in cells that have developed multiple drug resistance (MDR). To address this important problem, a biodegradable polymer was coupled to the photosensitizer and the resulting photosensitizer-nanoparticles were [...]

siRNA and Paclitaxel Loaded PEG-PCL-PEI Tri-block Polymeric Micelle for Gene and Chemo-therapy Applications in Multidrug-resistance cancer cell

Hsu C.Y., National Chung Hsing University, TW

An annoying problem of chemotherapy was the drug resistance of cancer cell which was expression of multidrug-resistance associated proteins and resulted in ineffective treatment. To conquer this problem, a small interfering RNA (siRNA) molecule and [...]
