Nitrogen-Doped Graphene-Oxide Quantum Dots as Photocatalysts for Overall Water-Splitting under Visible Light Illumination
Hsisheng Teng

We have recently succeeded in producing nitrogen-doped graphene oxide quantum dots (NGO-QDs) with large surface area and optimized functionalization. Visible-light illumination of NGO-QDs in pure water resulted in evolution of H2 and O2 at a molar ratio of approximately 2:1. We hypothesize that the unique character of the NGO-QDs are caused by p- and n-domains in the …

In vivo anti-cancer efficacy of magnetite nanocrystal - based system using locoregional hyperthermia combined with 5-fluorouracil chemotherapy
Dar-Bin Shieh

Hyperthermia (or thermotherapy) is one alternative cancer therapy available for advanced disease states.  Experimental results showed that by exposing tumor to temperature around 41-45C for a period of time can damage or kill cancer cells while only minimally injure normal tissue (Hartman 2008). Cancer lesions present intrinsic acidity and low oxygen environment which provide resistance to …

Ionospheric Disturbance Waves Generated by Rockets
Chien-Hung Lin

Similar to the bow and stern waves generated in the fluid (water surface for example) due to transition of an object, the upper atmospheric neutral density and ionospheric plasma could be disturbed by the rocket fly-by.  Using the dense ground-based GPS receiver network around East Asia, we observed disturbance wave signatures in the total electron contents (TECs) measured along the signal ray …

Multi-Index Hybrid Trie for IP Lookup and Update
Sun-Yuan Hsieh

High performance routers require high-speed IP address lookup to achieve wire speed packet forwarding. In this thesis, a new data structure of dynamic router table is proposed for IP lookup and updates, called Multi-Index Hybrid Trie (MIHT). By associating each prefix with a key value, we can perform an IP lookup operation efficiently in a balanced search tree. Furthermore, because the tree …
