The innovation proposed here is a novel carbon-carbon composite (CCC) manufacturing method based on polymer infusion and polymerization (PIP) using a novel precursor polymer with exceptionally high char yields. This results in a material that has the promise of excellent quality and mechanical properties, while offering the breakthrough advantages of (1) greatly reduced or eliminated need for back ...

Sivananthan Laboratories (SL) with the University of Iowa as the STTR partner, proposes to develop metasurface-coupled type II superlattice (T2SL) LWIR detectors that are predicted to outperform HgCdTe detectors. We developed in Phase I fundamental understanding of metasurface-coupled T2SLs, likely performance, and issues related to scaling up device structure to form arrays for LWIR imaging. In P ...

In Phase II, the Attollo team proposes to investigate the growth and fabrication techniques of LWIR SLS and associated variants to meet the target objectives. Our plan is to push the envelope further by increasing the absorption coefficient, improving the material quality and carrier lifetime, and reducing any surface leakage contribution from detector fabrication. At the end of Phase II, we expec ...

Ankle sprains occur frequently with military personnel and in the general population. An early diagnosis of an ankle sprain is crucial to prevent the development of chronic ankle instability and to decrease the need for further intervention. A portable device that can be used to evaluate and quantify ankle instability in any setting (clinical, residential, field, etc.) by conducting a variety of t ...

This topic identifies the need creating a Modeling and Simulation (M&S) development and execution environment that significantly decreases the time to execute statistically significant batches of stochastic simulation runs for the purpose of estimating scenario output and outcome distributions while improving statistical knowledge of the outcome distributions. The strategy sought by this topic is ...

The overall objective of the Phase II program is to develop and commercialize a portable, reliable, easy-to-use medical device called POMAS (Portable Oculomotor Multi-sensing Assessment System) (Figure 1) with associated software in order to enable non-invasive, fast, accurate and objective full spectrum oculomotor testing combined with 2 involuntary ANS (Autonomic Nervous System) measurements for ...

To advance simulation techniques, such as high-fidelity computational fluid dynamics (CFD), to accelerate maturation of DACS design through design-time trade studies, there is a need for new, test-validated models that improve both computational performance and the accuracy of the reacting jet in hypersonic crossflow simulations. ATA and CUBRC (a research institution with leading expertise in aero ...

The National Commission on Military Aviation Safety determined that between 2013 and 2020, 224 lives, and 186 aircraft were lost due to military aviation mishaps amounting to losses of $11.6 billion. It is well documented that there is a negative impact on mission performance and an increased risk of accidents associated with sleep deprivation, extended time on intense attention demanding tasks, p ...

The overall goal of this proposed project (through Phase III) is to develop the Tacrolimus At-home Saliva Test (TAST) to measure tacrolimus at ng/mL levels in oral fluid (saliva) at-home in 15-20 minutes.  The TAST will replace the painful blood tests currently performed at hospital and clinics that military patients, who have limb, facial and organ transplants, must undergo to avoid transplant r ...

Sb-based III-V semiconductor Type-II superlattice (T2SL) materials with band structure-engineered device architectures are groundbreaking for infrared detectors and focal plane arrays (FPAs). T2SL FPAs have become very attractive candidates for various MDA/DOD sensor platforms including air, space, ships, and missiles. T2SL wafers, the starting materials of FPAs, are grown on large substrates usin ...
