 | This proposal addresses the nacre in the abalone shell and the methods that will be taken to fabricate and test a bioinspired material based on its structure. Our objectives are 2-fold: (1) to fabricate a nano/micro-laminate that mimics the nacre in the abalone shell using engineering ceramic compositions and (2) to test these laminates and determine modes of fracture and energy absorption. The main focus is to distinguish the role ... |

| This supplement was dedicated to the development and modeling of phthalocyanine based chemical sensors. We used Organic Molecular Beam Epitaxy (OMBE) to prepare phthalocyanine based sensors. We lithographically patterned special electrode configurations and mounted them on a universal commercial carrier chip thus facilitating manufacturability in actual field testable devices closer to reality. Two types of metallo-phthalocyanine (M-Pc) based sensors were prepared; Co-MPc films 12 monolayer thick and 3 different kinds ... |

| This project was dedicated to the development of novel magnetic devices relevant to applications in the fields of sensors, storage, non-volatile, reprogrammable spin-based electronics. The devices envisioned in this project explored novel physical phenomena and new functionalities not yet explored. More specifically, devices the initial idea was to explore three types of phenomena will be explored: ballistic magnetoresistance, magnetic field proximity effect and spin drag. These three phenomena would then ... |

| The Department of Defense directive 4140.25 dated April 12, 2004 mandates that "primary fuel support for land-based air and ground forces in all theaters shall be accomplished using a single kerosene-based fuel, in order of precedence: JP-8, commercial jet fuel (with additive package), or commercial jet fuel (without additives)." The objective of the proposed research is to understand those key aspects of combustion of JP-8 that are required to facilitate ... |

| Optical control is fundamental to our project objective of demonstration of key quantum operations for quantum computation with spin qubits of electrons in semiconductor quantum dots. Sophia Economou, the graduate student supported by this fellowship, works on the design of optical control taking into account the deterioration of the quantum states of the electron spin and of the excited state during the optical control process. She has three major accomplishments: ... |

|
| This project developed new results in the topology and foundations of quantum algorithms. It made major developments in the program for topological quantum field computation, including the design of substantially simplified lattice models with topological phases, and new insights into the universality classes of such models. Lattice gas simulations of various classical and quantum systems were investigated. In addition, several new algorithms for structured search, concept learning, and image processing ... |

|
| We investigated new system software architectures that support mobile code, based on network (and distributed) computing. The primary goal was to support an application's reliance on network resources, rather than local ones (which are often scarce in defense mobile-computing situations), to meet their communication and computational demands. We have developed a powerful extension of the client/server model, which we call the Extended Client/Server (ECS) model of distributed computing. Rather than ... |

| The objective of this program was to advance the performance of the semiconductor waveguide modulator in externally modulated RF fiber-optic links for space-based and airborne platforms such as true time delay beam formation and beam steering subsystem in phased array antennas. Device and material approaches were investigated to improve the modulator based on semiconductor structures for achieving high spur free dynamic range (SFDR) and high frequency operation. In these approaches, ... |

|
 | The main goal of this program was to establish a low resolution map for the pore-forming structure of the N-methyl-D-aspartate (NMDA) receptor, a major excitatory neurotransmitter receptor thought to be crucial for synaptic plasticity and neurotoxicity. Open channel blocker libraries were used as specific probes to explore accessibility of pore lining residues and, accordingly, infer the intricacies of the channel structure. The functional assay to identify channel blockers from synthetic ... |
