 | The goal of the DARPA-AFOSR project is to develop multifunctional magnetic nanoparticle probes for deep-tissue imaging using MRI. The specific objectives of the Phase 1 project include: (1) to functionalize iron-oxide magnetic nanoparticles for bioconjugation of oligonucleotides and peptides; (2) proof-of-concept demonstration of the signal transduction mechanism based on nanoprobe clustering on mRNA target; (3) to develop peptide-based delivery of magnetic nanoprobes into living cells with high delivery efficiency; (4) ... |

| In this final report, we have summarized the progress made during the period of September 1. 2002-September 30, 2003. We derive the integral equations for (electric fields propagating in a fiber of arbitrary cross section and arbitrary refractive index. Mathematical analysis of conventional optical fibers is rich and widely available in literature, for example 3, 9, 11 and references therein. It helps the advancement of optical fiber industry in understanding ... |

| Under the support of ARO (Grant number: DAAG55-98-1-0133, Engineering Sciences Division), a three-year basic research program is carried out on the micromechanics of penetrator/target interactions. Emphasis is placed on the basic models for penetrators and targets in the interfacial zone, aiming to provide guidelines for the design of advanced armor/antiarmor systems. The outcomes of this three-year program include: (1) A better understanding of the fundamental relationship between the high strain ... |

|
| This 3-year research program focuses on micromechanics and fracture mechanics analyses of cracking in functionally graded coating/substrate systems used in turbine engines and wear-related applications. Functionally graded materials (FGMs) are new advanced composites whose composition varies from place to place according to performance requirements. Recent developments of FGMs have demonstrated that functionally graded materials have the potential to enjoy a wide range of thermal and structural applications including thermal barrier ... |
