Nutrient pollution caused by excess nitrogen and phosphorus in the water is a costly and challenging environmental problem with widespread negative health and ecological effects. During Phase I XploSafe successfully confirmed the technical feasibility of using its proprietary low-cost biodegradable sorbents to passively adsorb target nutrient ions (ammonium, nitrate, urea, and phosphate) from prim ...

The extended short wavelength infrared (e-SWIR) wavelength band is in a performance gap for infrared detectors. At both shorter and longer wavelengths high performance detector technologies exist: SWIR InGaAs detectors (1.7 m cutoff), and MWIR (3-5 m cutoff) detectors such as InAs-based and GaSb-based Unipolar Barriers, MCT, and InSb. This program proposes development of high performance e-SWIR de ...

This proposal presents a non-invasive device to reduce, and control, intracranial pressure in the event of a traumatic brain injury (TBI). The device is compact, rugged, light, and easily transported by medics or civilian first responders in the field.

Traditional manufacturing methods for producing warheads, propellants, and pyrotechnic systems are timely and costly. Additive manufacturing (AM) approaches offer one path of alternative manufacturing technologies. Among various technologies, powder bed fusion (PBF) is one promising approach. Hewlett Packards Multi-Jet Fusion printers utilize a unique PBF process that presents a desirable solution ...

A need exists to improve the ballistic response of armor for Littoral Combat Ships. Simply increasing armor thickness is unacceptable because the associated increase in weight and space would reduce vessel performance speed and range. Surface treatment techniques for current armor materials such as steel, aluminum and ceramic may improve armor performance significantly without an associated weight ...

Eagle Harbor Technologies, Inc. (EHT) is collaborating with researchers at the Pulsed Power and Power Electronics Center at Texas Tech University (TTU) to develop a high-power microwave switch that is capable of very fast rise times, adjustable pulse width, and high pulse repetition frequency (PRF). EHT has developed solid-state pulsed power systems that has the potential to improve the performanc ...

The Air Force has identified a need for a display agnostic common streaming model for 3D data. Third Dimension Technologies (TDT) and Oak Ridge National Laboratory (ORNL) have formed a consortium to define a 3D streaming model based on open standards for Display Agnostic 3D Streaming (DA3DS). Two factors are driving this need. The first is the dramatic increase in the collection, storage and trans ...

SciGenesis will apply its FR-technology to nylon-only and nylon/cotton (50/50) blended yarns to demonstrate the feasibility of this technological platform at the individual yarn stage (i.e. pre-woven). The unique FR chemistry that SciGenesis has developed encompasses char promoting agents, heat reflective particles, Lewis-acid catalysts and a laundering durable binding system. Implementing this ...

S-RAM Dynamics (S-RAM) proposes to design, fabricate, test, and commercialize a high-performance axial piston transcritical CO2 energy recovery compressor (ERC) to support next-generation aircraft thermal management systems for the U.S. Air Force and commercial applications. The S-RAM ERC will be developed and commercialized with the support of the Rolls-Royce Thermal Management System team and Pu ...

In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...
