The goal of this proposal is to fabricate a capacitor with an energy density of at least 4 J/cc that is durable over 10,000 cycles with an operational temperature range of -55 °C to 300 °C. This goal requires that a new thermally stable, high dielectric constant material be developed. It is proposed that such a dielectric layer can be achieved using nano-composites. In particular, high dielec ...

The Air Force Research Laboratory (AFRL) desires a method to map Automatic Target Recognition (ATR) performance to signature performance in order to aid database optimization.  To better understand the physical mechanisms relating the sensing platform, candidate ATR algorithms, and the classifier database, advanced radar signal processing models are required.  Analytic Designs, Incorporated (ADI ...

Applied Optimization, Inc. herein proposes three technical tasks for modeling of electron-beam free-form fabrication [EBF3] as follows. The first task is to enhance existing capability to simulate melt-pool generated by the electron-beam, and evolution of its shape due to interaction between thermo-mechanical and geometry phenomena. The second task is to enhance the existing simulation capability ...

Electrostatic precipitators (ESPs) are a key pollution control device in air pollution control devices for small oil and coal-fired industrial boilers. ESPs can operate with an efficiency of 98 to 99% for the removal of mercury and fly ash from the flue gas stream. With an electrostatic precipitator fly ash particles are charged electrically as the flue gas passes through the precipitator allowi ...

This Phase I effort will demonstrate the production of large area carbon nanopaper prepreg mats with very high electrical conductivity and EMI shielding capabilities. Currently, metal structures, metallic fillers, and metallic coating are used to provide ESD and EMI shielding, but issues such as weight and corrosion make these materials less than ideal. Carbon nanotubes and nano graphene platele ...

Pursuits of highly efficient and reliable solar cells place high demands on the materials and processes used in their fabrication. For extraterrestrial cells, specific efficiency is of utmost importance, and thus the ability to reduce module weight without impacting efficiency is highly desirable. Flexible solar cells are a new direction in solar cell technology and robust substrates are required. ...

In this Phase I effort our team, a collaboration between Traycer Diagnostic Systems and The University of Notre Dame, proposes to develop a single pixel detector of terahertz frequency electromagnetic radiation. The devices we propose are AlN/GaN high electron mobility transistors which, via the excitation of plasma waves in the device channel, exhibit a nonresonant broadband and resonant respons ...

Stand-off inspection using THz sources is a promising technology for non-destructive evaluation by means of direct imaging as well as by identifying spectroscopic signatures of the material being inspected. This proposal addresses critical developments for realizing this promise. In particular we address the issue of developing THz sources to the point where stand-off detection at ranges of 3-5 ...

High Power Microwave (HPM) systems penetrate electronic equipment front ends and cause substantial damage to critical components by generating extremely high energy via a very short electromagnetic pulse. Enclosing an HPM radiating aperture with a frequency selective surface (FSS) radome presents a unique problem. The power density seen by HPM radomes is on the order of 10,000 times more than is t ...

Determining the hazard classification of new propellant formulations is important for transportation safety and storage concerns. To avoid costly grain redesign and additional testing, a model that adequately predicts the shock sensitivity, including the outcome of the Naval Ordnance Laboratory Large Scale Gap Test, of modern solid propellants is required. The goals of this proposal are to develop ...
