The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens'principl ...

Antimicrobial treatments have been incorporated in a number of textile products used by the U.S. Army to control odor and reduce skin irritation, thus improving the quality of life for the warfighters. Current textile treatment using chemically-derived antimicrobials such as metals (silver- and copper-based compounds), polyphenols, halamines and quaternary ammonium compounds can effectively kill o ...

Skin infections caused by bacteria represent a significant risk to wounded soldiers. The most common source of bacterial infection is found in the fabrics of clothing, boots, and gear worn by the warfighter. Reducing the risk of infection for soldiers by treating the source fabrics will lead to positive outcome and support medically-related activities in non-sterile environments encountered by t ...

The overall objective of this proposal is to evaluate the new in-situ growth monitoring system, Auger Probe, in an MBE environment for reliable and reproducible, highly precise results. State-of-the art data manipulation techniques will be used without impacting the growth process (MBE in this case). Using Auger Electron Spectrometry (AES), the Probe system will be used for in situ, real time an ...

The area of thin film growth has progressed rapidly, producing many high performance new materials which require accuracy of their atomic composition to perform as expected. Any method to provide real time in situ information about the elemental composition of the growing surface is highly valuable for these new, complicated materials. Utilizing a new instrument design, the Phase I project team ...

The proposed work will result in a method for production of dense, hard, tough, strong tungten carbide (WC) ceramic material for ultimate use as the penetrating core in armor piercing projectiles. Focus is on the development and feasibility of a titanium silicon carbide (Ti3SiC2) based matrix as a replacement for cobalt based materials currently used. Ti3SiC2 is a so called ductile ceramic which ...

The aim of this STTR program is to develop protocols to discover rare-earth-free/rare-earth-lean magnetic alloys for replacing rare earth (RE) -based alloys for reducing the dependence of supply from China. The development of non-RE high temperature magnetic materials is very challenging. In Phase I, CFDRC in collaboration with its university partner has demonstrated a proof-of-concept computation ...

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 the tubular anode will be produced using a novel freeze-casting tec ...

A technique that enables new methods of obscurant modeling with faster rendering while maintaining or improving physical fidelity is proposed. The proposed technique not only exhibits the statistics of voxel based obscurants, but matches real-world data as well. The main objective from Phase II efforts will be a further refinement of the flow field and particle technique of generating physically c ...
