Investigation of Mechanical Strength of the Nanoshell of Bacteriophage Phi-29

Han C-N, Chou C.Y., Chiang K.N., National Tsing Hua University, Taiwan, TW

In this research, by using the analytical solution (method 1, method 2) and finite element method that include three approaches were proposed to find the stress in the nanoshell when phi-29 packages the dsDNA. Method [...]

Investigation of dsDNA Molecule Mechanical Behavior using Atomistic Continuum Mechanics Method

Han C-N, Chou C.Y., Wu C-J, Chiang K.N., National Tsing Hua University, TW

In this research, an atomistic continuum model of dsDNA based on equivalent-spring method would be first conducted and the simulation result would be further validated by the experimental result. A spring element is chosen to [...]

Investigation of the ssDNA Backbone Molecule Mechanical Behavior Using Atomistic-Continuum Mechanics Method

Han C-N, Chou C.Y., Wu C-J, Chiang K.N., Advanced Microsystem Packaging and Nano-Mechanics Research Laboratory, National Tsing Hua University, TW

As is known, various important physiological functions and gene engineering processes, such as RNA transcription/DNA replication/DNA repair, involve specific bio-physical mechanics of DNA. Therefore, in this study, a novel single-stranded DNA (ssDNA) model based on [...]

Investigation of Carbon Nanotube Mechanical Properties Using Atomistic-Continuum Mechanics Method

Wu C-J, Chou C.Y., Han C-N, Chiang K.N., Advanced Microsystem Packaging and Nano-Mechanics Research Laboratory, National Tsing Hua University, TW

This paper utilizes atomistic-continuum mechanics method (ACM) to investigate the mechanical properties of single-walled carbon nanotubes (SWCNTs). Fundamental to the proposed concept is the perception that a carbon nanotube is a geometrical frame-like structure, and [...]

Investigation of Local-Strain Effect of the Nano-Scale Triple Gate Si/SiGe and SiN/Si Stacking MOS Transistor

Chang C.H., Chou C.Y., Peng C.T., Han C-N, Chiang K.N., National Tsing Hua University, TW

The tensile strained Si, based on the misfit between Si and SiGe gives higher speed and higher drive current for the metal oxide silicon field effect transistors. Based on the strained Si technology, a tri-gate [...]

Investigation of the Sequence-Dependent dsDNA Mechanical Behavior using Clustered Atomistic-Continuum Method

Yuan C.A., Han C-N, Chiang K.N., National Tsing Hua University, TW

A novel clustered atomistic-continuum method (CACM) based on the transient finite element theory is proposed herein to simulate the dynamic structural transitions of the double strand DNA (dsDNA) under external loading. Moreover, the meso-mechanics of [...]
