The proposed research effort is focused on developing a highly conducting, nanostructured membrane for use in high temperature direct methanol fuel cells (DMFC). Polymer nanofiber mats with high temperature stability and water retaining inorganic nanoparticles will be prepared through electrospinning process. The nanofiber mats will be compacted and the pores will be infiltrated using a hydrophobi ...

Active defects negatively impact the performance of IRFPAs by increasing noise at various levels up to, and including, catastrophic degradation. Evidence indicates that"killer defects"are related to the interaction of open core screw dislocations with impurities that remain after substrate preparation, prior to HgCdTe growth. This impurity diffusion creates a conducting channel that shorts the j ...

For HgCdTe infrared focal plane arrays fabricated on Si substrates, a model has recently been proposed to account for the disparity between the density of failed pixels and the density of dislocations that are present in the HgCdTe junction region. The model distinguishes between active and inactive dislocations and offers a hypothesis that dislocations are active only when they intersect particul ...

Silicon wafers oriented on (112) are the preferred substrates for deposition of mercury cadmium telluride layers by molecular beam epitaxy. Surface defects introduced during polishing of the wafers degrade the quality of the epitaxy and the performance of infrared detectors fabricated within these materials. We propose a process for reducing the density of the defects that are inherent in the si ...

This proposal seeks to develop novel, widely tunable bandstop filters for the suppression of co-site interference in next generation phased array radar and electronic warfare systems. The filters are based upon highly loaded evanescent mode cavity resonators that are integrated into standard printed circuit board substrates. This integration and design strategy yields high resonator Q performance ...

In coordination with the SPAWAR Systems Center, San Diego, Makai Ocean Engineering, Inc. proposes to develop an autonomous Array Burial Vehicle (ABV) to install U.S. surveillance arrays. The proposed work focuses on: (a) developing an overall vehicle concept for an autonomous vehicle that will install and bury an underwater sensor array to protect it against fishing threats, (b) performing analyti ...

In this proposal, the team of Archinoetics and UCI define a program of research and development to develop a data collection and analysis system for human performance measurement that is (1) inexpensive, (2) modular, (3) easily extensible, and (4) that facilitates easy data analysis. Furthermore, in creating such a system, we will be leveraging know-how, lessons learned, as well as some technical ...

The focus of this project is on large-eddy simulation (LES) of high-speed turbulent reacting flows. The Enabling Energy Systems (EES) Inc., has assembled a well-experienced team of experts to tackle all the main issues involved in modeling of such complex flows. The members of this team are proposing several innovative ideas and have a long history of working together with complementary expertise. ...
