ABSTRACTHigh power density micro-systems offer the potential to revolutionize technologies for portable electrical power generation, propulsion and flow control. Devices are being designed and fabricated which include micro-gas turbine engines, micro-rocket engines, micro-motor- compressors, micro-pumps and micro-hydraulic transducers. Common to all of this family of devices is the need to create packages that service the devices, and interface them with the macro-scale environment. Fluid interconnections are a particularly demanding packaging element for this class of devices. In order to ach

AbstractMaterial variations on an atomic scale enable the quantum mechanical functionality of devices such as resonant tunneling diodes (RTDs), quantum well infrared photodetectors (QWIPs), quantum well lasers, and heterostructure field effect transistors (HFETs). The design and optimization of such heterostructure devices requires a detailed understanding of quantum mechanical electron transport. The Nanoelectronic Modeling Tool (NEMO) is a general-purpose quantum device design and analysis tool that addresses this problem. NEMO was combined with a parallelized genetic algorithm package (PGAP

Abstract:
ABSTRACTNominally smooth surfaces subjected to repeated contact may develop characteristic fretted textures. An important example concerns fretted surfaces that may develop on disk dovetail joints that secure fan blades in turbine engines. These surfaces may form sites for crack nucleation and subsequent catastrophic disk and engine failure. Thus a practical and reliable method for the nondestructive evaluation of such fretted surfaces is critically needed. In this paper straightforward optical techniques are considered for identifying and quantifying fretted (and other surface damaged) region

AbstractIntermetallic-matrix composites (IMCs) are intended for applications involving higher temperatures and stresses than conventional metallic matrix composites. Consequently, environmental effects, thermo-mechanical fatigue, interfacial thermodynamic stability, creep resistance, processing and cost are only a few of the obstacles to introduction in real products. The primary goal of current IMC development efforts is to provide ‘revolutionary’ materials for components that are enabling technologies in advanced demonstrator gas turbine engines.

ABSTRACTPolymeric light emitting devices may be fabricated from a simple structure consisting of a low work function cathode (typically calcium or Magnesium), a conjugated semiconducting polymer and a transparent anode (typically indium-tin oxide).

This paper describes the application of molecular engineering in the design of a family of poly (cyanoterephthalylidenene) s which show increased electron affinity over the unsubstituted analogue [poly (p-phenylenevinylene) PPV].

This domain is thermally stable, exhibits a highly reversible folding and unfolding equilibrium, and recognizes IgG and Fab molecules with high affinity. These properties make the protein G domain a potentially useful adaptor for non-covalent immobilization of antibodies to soluble polymers and hydrogels. Engineered single-chain Fv

ABSTRACTGrowth factor delivery using polymer matrices is one exciting approach to replace or regenerate tissues.

Considering the dynamic environment of our body (e.g., bone, muscle, and blood vessel), mechanical stimulation is an important signal that could be readily exploited. We hypothesize that polymer matrices, which release growth factors in response to mechanical stimulation, could provide a novel approach to engineer tissues in mechanicall
