There is a military and industry need for easy-to-use, versatile alloys for metals additive manufacturing (3D printing) that print consistently regardless of the specific process or machine and without requiring in-depth metallurgical or manufacturing knowledge. Such capability is critical for soldiers to be able to make needed items on demand in the theater of war. In addition, the alloy will be ...

Physically uncloneable functions (PUFs) have the potential to revolutionize cybersecurity by forming the basis for next-generation secure networks and trusted computing environments. During Phase I, Potomac Research and OSU evaluated of three physically uncloneable function (PUF) designs that can be implemented on COTS FPGAs. One design based on hybrid Boolean networks (HBN-PUFs) emerged as the cl ...

Predicting the emission signature and radar cross-section of rocket exhaust plumes is of vital interest to the Missile Defense Agency and U.S. Army to protect the U.S. homeland and our forces abroad.  The current STTR Phase II project has shown that a single-conditioned Premixed Conditional Moment Closure (PCMC) can employ detailed chemical kinetic mechanisms while efficiently modeling combustion ...

Solid oxide fuel cells have long suffered from degradation due to impurities in the fuel and complexities associated with dissimilar materials and high operating temperatures. This degradation lowers the usable cell power output and requires ancillary equipment for fuel sulfur removal and reformation. A unique microstructure for a tubular anode-supported SOFC is being developed using a novel freez ...

With current events and the focus on homeland defense, there has been much interest in rendering materials biocidal. This Phase II effort will build on the feasibility demonstration of Phase I where Luna covalently bound biocidal molecules to a commercially available textile sample, and tested the newly modified textile for resistance to different strains of bacteria. The mechanical properties of ...

We propose the prototype development of a miniature W-band dielectric traveling-wave tube (DTWT) that will provide short-wavelength radiation for the Army's Network-centric Objective Force. The DTWT is based on the novel interaction between a small-diameter electron beam and the electromagnetic fields of a traveling wave inside a very compact dielectric waveguide. The dielectric waveguide is used ...

Sentor Technologies Inc. proposes to develop and demonstrate a new STEALTH chem/bio sensor technology based on differential fluorescence from molecularly imprinted polymers. In the phase I project period, the feasibility of both the STEALTH sensor as well as an integrated vapor sampler/concentrator based on the charged nanodroplets produced from an electrospray source was successfully demonstrat ...
