Motional modes of dilatational waves in elastic porous media containing two immiscible fluids
Wei-Cheng Lo

1. RESEARCH OBJECTIVES

Wave excitation in an elastic porous medium generates dynamic stress-flow coupling in which the deformation of the medium influences the flow of the pore fluids, and vice versa, thus producing a time-dependent behavior known as poroelasticity.  Poroelastic phenomena at wave excitation frequencies in the seismic range (< 250 Hz) are of particular interest …

Fractionation correction methodology for precise and accurate isotopic analysis of boron by negative thermal ionization mass spectrometry based on BO2 ions and using the 18O/16O ratio from ReO4 for internal normalization
Chen-Feng You

A novel approach to obtain fractionation free 11B/10B isotope ratio by N-TIMS, based on oxygen isotopes is described. The method uses only a few ng B and BO2- ions are employed. The oxygen isotopes are determined employing 187Re/185Re for internal normalization and pre-determined 18O/16O isotopes is used to …

A Microchip Fabricated with a Vapor-Diffusion Self-Assembled-Monolayer Method to Transport Droplets Across Superhydrophobic to Hydrophilic Surfaces
Dar-Bin Shieh

A novel method which combines microstructure patterning and SAM techniques to fabricate a microchip across superhydrophobic to hydrophilic surface to transport a droplet is proposed. The gradient from superhydrophobic to low hydrophilic surface is formed by a saturated decyltrichlorosilane(DTS) assembled on the microstructure gradient surface with the decreasing density. On the other hand, …

A systematic investigation into the electrical properties of single HeLa cells via impedance measurements and COMSOL simulations
Ling-Sheng Jang

Introduction

In recent years, many researches have attempted to eradicate diseases in earliest stages. However, in the case of diseases such as cancer, conventional cell inspection techniques do not generally provide sufficient information to provide a reliable diagnosis since only a very small percentage of the cells exhibit symptoms of malfunction during the early stages of the …
