| 47 |  |  |  | 
| 48 | tim | 2907 | As a rapidly expanding interdisciplinary science bridging physics, | 
| 49 |  |  | chemistry and biology, the study of soft condensed matter involves | 
| 50 |  |  | the kinetics, dynamics and geometric structures of complex materials | 
| 51 |  |  | like membrane, liquid crystal and polymers. These soft condensed | 
| 52 |  |  | materials are distinguished by the unique physical properties on the | 
| 53 |  |  | mesoscopic scale which can provide useful insights to understand the | 
| 54 |  |  | basic physical principles linking the microscopic structure to the | 
| 55 |  |  | macroscopic properties. Knowledge of the underlying physics is of | 
| 56 |  |  | benefit to a wide range areas, such as the processing of | 
| 57 |  |  | biocompatible materials and development of LCD display technologies. | 
| 58 |  |  | Although the separation of the length scales allows statistical | 
| 59 |  |  | mechanics to be applied, the interesting behavior of these systems | 
| 60 |  |  | usually happens on time scale well beyond current computing power. | 
| 61 |  |  | In order to simulate large soft condensed systems for long times | 
| 62 |  |  | within a reasonable amount of computational time, some new | 
| 63 |  |  | coarse-grained models are presented in this dissertation to describe | 
| 64 |  |  | phospholipids and banana-shaped liquid crystals. Although these | 
| 65 |  |  | models can be described using a small number of physical parameters, | 
| 66 |  |  | it is not trivial to introduce rigid constraints between different | 
| 67 |  |  | molecular fragments correctly and efficiently. Working with | 
| 68 |  |  | colleagues, I developed a new molecular dynamics framework capable | 
| 69 |  |  | of performing simulation on systems with orientational degrees of | 
| 70 |  |  | freedom in a variety of ensembles. Using this new package, I studied | 
| 71 | tim | 2911 | the structure, dynamics and transport properties of the biological | 
| 72 |  |  | membranes as well as the the phase behavior of banana shaped liquid | 
| 73 |  |  | crystals. A new Langevin dynamics algorithm for arbitrary rigid | 
| 74 |  |  | particles is also presented to mimic solvent effects which may | 
| 75 |  |  | eventually expand the time scale of the simulation. |

| 91 |  |  | \noindent I would like to thank my advisor, Dr. Gezelter for his inspiring and encouraging way | 
| 92 | tim | 2878 | to guide me to a deeper understanding of molecular modeling. Without his encouragement and constant | 
| 93 | tim | 2685 | guidance, I could not have finished this dissertation. I am also grateful to my colleagues | 
| 94 |  |  | Charles F.~Vardeman II, Christopher J.~Fennell, Xiuquan Sun, Yang Zheng, Kyle Daily, | 
| 95 |  |  | Kyle S.~Haygarth, Matthew A.~Meineke, Dan Combest, Pat Conforti, and Megan Sprague, | 
| 96 |  |  | who were always here for technical help and moral support. Last, but not least, | 
| 97 | tim | 2867 | I thank my family: my fater, Zongzan Lin, and my mother, Rongying Chen, | 
| 98 |  |  | for unconditional support and encouragement to pursue my dreams, | 
| 99 |  |  | even when they went beyond boundaries of language and | 
| 100 | tim | 2690 | geography. My wife, Xi, for her understanding and love during the past few years. Her support and | 
| 101 | tim | 2685 | encouragement was in the end what made this dissertation possible. |
