Accurate real-time waterborne pathogen detection is of paramount importance to security of U.S. military forces and installations. Fieldable high-throughput pathogen concentration is a critical analytical need for enhanced detection performance. Existing concentration methods are time-consuming, bulky, labor-intensive, power- and reagent-hungry, and consequently ill-suited for battlefield deployme ...

Phase I objective is to demonstrate the feasibility of our proposed passivation approach to minimize the dark current noise and improve the quantum efficiency in the GaSb based type II superlattice detectors. Phase I goal is to demonstrate the feasibility of our technology to fabricate photodiodes with cut-off wavelength in excess of 10µm, quantum efficiency exceeding 70% and dark current density ...

Aging aircraft commonly suffers from several types of degradation including fatigue cracking and lack of bonding. It is virtually impossible to predict degradation in structural performance or when a component or structure will fail due to the inability to test new material systems under all loading conditions and under all environmental conditions. A material state awareness system using minimali ...

Hypersonic missile defense systems are being designed to reach global threats. During flight, external surfaces are predicted to reach temperatures in excess of 2200C. As a result, innovative, high performance thermal protection systems (TPS) are of great demand. Among ultra-high temperature ceramics (UHTC), it is well known that ZrB2- and HfB2-based materials have high melting temperatures and ...

A military without good leadership is a mob. Identification, preparation, guidance and mentoring of potential leaders are critical functions across all services. Leadership training and support can be substantially improved by refinement of theories and models on what constitutes good leadership, and what enables individual to be effective leaders. DoD needs better models of how leaders learn, ...

Recent times have witnessed enormous advances in high fidelity modeling of electromagnetic (EM) phenomena in the time-domain. To make such simulations tractable, the computational region must be truncated in a manner allowing outgoing waves to leave with minimal reflection from the boundary. HyPerComp Inc., in collaboration with Prof. Thomas Hagstrom of the Southern Methodist University (Dallas, T ...

Detecting explosives and weapons under clothing or in hand carried packages, and imaging terrain and objects through fog and smoke are two high-priority needs that can be met using light in the Terahertz frequency range. However, to image concealed threats, and aid in navigation in fog and smoke, a practical, low cost THz camera is needed. Intelligent Optical Systems (IOS) in collaboration with Re ...

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 ...

We propose to develop a universal atomic magnetometer magnetometer capable of operation as either a three-axis vector atomic magnetometer or a scalar (total field) atomic magnetometer. We furthermore operate the magnetometer in a regime that is inherently free of sources of drift in the lasers or cell to achieve unprecedented low drift at low frequency. The magnetometer is being developed for volu ...

Genome-scale predictable cellular design and engineering of biomanufacturing systems is the overarching a goal of DARPA's Living Foundry thrust and, if realized, will enable rapid engineering of living biosystems for a broad range of applications in biotechnology and pharmacology. However, constructing living cells with designed genome is not fully automated and is severely limited by inhere ...
