 | The goal of this project was to use DNA and protein as templates to assemble nanoparticles and functional molecules for photonic and electronic applications such as plasmon-enhanced fluorescence and surface-enhanced Raman scattering (SERS) (Fig. 1). Towards this goal, we have utilized both genetic and materials engineering tools. We have followed the molecular biomimetic approach in the assembly of nanoparticles. We have developed protocols using involving biological attachment of nanoparticles and ... |

| The overarching goals in this DURINT project have been: 1. Combinatorial selection and post-selection engineering polypeptides that have specific affinity to inorganic surfaces (GEPI); 2. Understanding the nature of protein molecular binding on inorganic surfaces using experimental and theoretical tools; 3. Use these polypeptides as molecular tools to assemble and make nanostructures, and 4. To develop hybrid complex materials with nanoarchitectures, composed of peptides, polymers and nanoinorganics for electronic, photonic, ... |

|
 | Sixty-70 micron diameter preceramic fibers, extruded from THF solutions containing 1:2:3 stoichiometric mixtures of yttrium, barium, and copper carboxylates, were pyrolytically transformed into ceramic fibers using controlled heating schedules and reactive atmospheres. The objectives of the work reported here were to identify appropriate processing conditions such that during pyrolysis the preceramic fibers would (1) eliminate the organic glands without pore or void formation, (2) reach full density with a controlled ... |

|
| The temperature coefficient of electrical resistivity (TCR) of the commercial Ti-15-3 alloy is negative, if the alloy is in the 100% beta condition; the TCR increases from negative to positive values as a result of precipitation of the omega and alpha phases during ageing; an incubation or transient period, during which the value of TCR remains essentially unchanged, precedes the formation of the omega phase; this transient period decreases with ... |

|
| The structure and elastic properties of ni/cu and ni/au multilayer systems are investigated as a function of the number of ni monolayers built into the systems. we employed lattice statics simulations with the interatomic potentials described by the embedded-atom method. for the ni/cu systems, coherent interfaces and fcc structure are maintained, and no elastic anomaly is found. for the ni/au systems, when the ni layers are thick enough, they undergo ... |

|
| The development of chemical processing methods for the fabrication of glass and ceramic shapes for photonic applications is frequently Edisonian in nature. In Part, this is because the numerous variables that must be optimized to obtain a given material with a specific shape and particular properties cannot be readily defined based on fundamental principles. In part, the problems arise because the basic chemistry of common chemical processing systems has not ... |

|
| The spontaneous alignment of molecules in liquid crystalline solutions is characteristic of other materials that contain rodlike particles. We are developing a model to predict the evolution of microstructure in these systems. Its starting point is Flory's thermodynamic analysis of liquid crystalline phase separation. Our preferred method dispenses with the traditional lattice model in favor of a Monte Carlo simulation to calculate entropy. Some advantages and consequences of our approach ... |

| Working principles are developed as guidelines for the selection and/ or design of organometallic polymers for processing fiber precursors to metal oxide fibers. these principles from the basis for the selection of metal carboxylate preceramics as an optimal approach to processing yttrium, barium cuprate (123) ceramic superconducting fibers. a variety of candidate yttrium, barium, calcium, strontium, bismuth, and copper metal carboxylates were synthesized. solubility and empirical rheology test were conducted ... |

|
| The effects of intercalation with Br (residue) or CuCl(2) on the diameters d, microstructures, Young's moduli E, tensile strengths S and electrical conductivities of P-100 and P-120 fibers were determined using single filament methods. Circular cross section P-100, with an uncracked radial transverse texture, developed small axial cavities and longitudinal surface cracks on CuCl(2) intercalation, whereas the elliptical P-120 fibers with a "Pan Am" texture became more circular without evident ... |
