Advanced ordnance and propulsion systems utillize materials, such as RDX and HMX, that provide good performance but cannot meet todays more stringent safety and environmental requirements. Unfortunately, in newer compounds created to replace them, the performance falls with the sensitivity. The ORBITEC team proposes the development of new energetic materials that will be both high performance and ...

Biological tissues collection is problematic and risky even under ideal conditions; when collection occurs in remote locations, or by minimally- trained personnel, as may occur in response to an emerging disease threat, risks are magnified. This proposal addresses this issue by developing a Field Fixation Unit (FFU) for specimen collection that utilizes single-use capsules pre-loaded with fixative ...

There is a critical need for the development of dynamic IR materials that can be used to form device level components and systems necessary for mid to long wave infrared (3-12 µm) applications. To meet these future needs, the team proposes to develop tunable optical elements based around metamaterial surfaces or metasurfaces. Metasurfaces are a class of engineered materials where arrays of sub-wa ...

xß-Ga2O3 has emerged as a potentially disruptive semiconductor with a predicted breakdown field of ~8 MV/cm which is more than twice the breakdown field for the incumbent wide bandgap semiconductors GaN and SiC. The availability of ß-Ga2O3 bulk substrates sets this material apart from other wide bandgap materials for power electronic applications. However, the challenge is to find suitable epita ...

The heat load from Navy combat system electronics housed in Mission Critical Enclosures (MCEs) continues to increase. During Phase I, Mainstream designed and demonstrated a modular, scalable thermal management system (TMS) for existing and future MCE cabinets with triple the cooling capacity of the legacy TMS. In Phase II, Mainstream will transition the TMS to the Navy for retrofit and next-genera ...

The primary objective is to develop a commercially-viable prototype of the slope adaptive prosthesis design and to iteratively improve the design based on ISO standards testing and rigorous use in human subject field trials. The proposed work will build upon knowledge gained in Phase I of the project, which established feasibility for this design approach in a lightweight, passive hydraulic foot-a ...

Providing Army combat medics with meaningful experience in treatment of battlefield injuries is a particular challenge. Moulage has the potential to assist in acquiring what could otherwise be very hard-to-come-by preparatory experience for distressing real-life emergencies medics and soldiers may encounter in the field. However, current approaches to moulage are limited in their ability to reflec ...

The technical objectives of this proposal are: 1) Design a metal/semiconductor grating-based (i.e., substrate-emitting) Grating-Coupled Surface-Emitting Distributed Feedback Quantum Cascade Laser (GCSE-DFB QCL) emitting at 4.6 microns with high beam quality; and 2) Demonstrate a GCSE-DFB QCL emitting at 4.6 microns with single-lobe-beam operation and high beam quality, under CW operation. It is th ...

This Small Business Technology Transfer Research (STTR) Phase II proposal from Materials and Systems Research, Inc. (MSRI) and University of Utah (research institution) seeks to fabricate single-phase, polycrystalline tungstate ceramics with densities greater than 99.95% and a mean grain size of less than 1 um. These ceramics have been chosen because of their low thermal expansion and low elastic ...

The United States is currently faced with unprecedented energy challenge. Petroleum prices have skyrocketed due to rising competition for energy resources from emerging economies. There is a significant need for processes that can produce hydrocarbons from renewable resources rather than petroleum. The use of renewable resources ensures a long-term supply of hydrocarbons, even after easily extract ...
