We propose the development of a membraneless water purification system using continuous, self-contained, vacuum-assisted diffusiophoresis. Using diffusiophoresis allows the system to clean water contaminated with particulates and bacteria without membranes or filters, while producing a stream of fresh, drinkable water. The system will operate using only electricity supplied by portable batteries/s ...

Thermopile arrays manufactured using integrated process compatible materials and micro-machining will provide high performance with low manufacturing cost. Black Forest Engineering (BFE) teamed with Case Western Reserve University will design thermopiles using silicon based semiconductors and compare performance. Low cost thermopiles, differentially coupled with advanced BFE CMOS readout, will pr ...

Metal Additive Manufacturing (AM) research has typically addressed understanding how to maximize performance for an AM material, taking into account microstructural anisotropy, residual stress, defects (such as pores and lack of fusion defects), and surface finish. Optimizing a part then requires significant post processing such as hot isostatic pressing (HIP), heat treatment and surface finishing ...

Ransomware is terrorizing the Internet, running rampant in consumer, business, and government systems. So far, ransomware-specific defenses have had minimal impact or success. We propose a new technology called RAM Journaling, a selective recording of RAM over time. The primary purpose of the journal is the recovery of locked data. Specifically, the journal is searched for the symmetric cryptograp ...

The Army has a clear need for a small unmanned ground vehicle (UGV) capable of autonomously accompanying a single soldier or vehicle. Such a UGV would help solve both logistical problems of soldiers needing to transport more equipment and supplies than they can carry in a backpack, and tactical problems of scouting unsafe areas. Multiple designs for such UGVs exist; however, they require active re ...

Built upon the progress in Phase I period, Winchester Technologies, LLC is pleased to propose to investigate practical magnetoelectric antennas during the Phase II period based on solidly mounted resonators (SMR), which will have enormous impacts on DoD and civilian antenna applications. State of the art antennas suffer from three major open challenges: (1) large antenna size > ?0/10, (2) antenna ...

This Small Business Technology Transfer Research program will develop narrow band plasmonic resonant cavity filters with integrated microbolometer sensors operating in the long wave infrared (LWIR) atmospheric transmission band for IR absorption measurements of low concentration chemicals. IR spectroscopy can identify a wide range of contaminants, including chemical/biological warfare agents, exp ...

A narrow-band microbolometric detector is proposed to the address need for a low-cost, portable system to perform chemical and biological threat detection. An approach is shown to achieve a narrow-band bolometric detector whose response can be tailored to both a desired peak wavelength and bandwidth. The approach will enable the design of an array of detectors meeting the requirements for chemical ...

SRICO proposes to combine metamaterial narrowband absorbers and SRICO-proprietary thin film lithium tantalate (TFLT) pyroelectric thermal detectors to produce ultra low cost, size, weight and power (SWaP) room temperature stand-off chemical sensors. Metamaterial narrowband absorber elements will be integrated into the TFLT pyroelectric detector process to provide conversion of radiation to heat, w ...

The neurocognitive health of U.S. service members plays a vital role in the defense of the United States. It is critical to a service member"s effectiveness, to force readiness, and it is a key component of a service member"s successful reintegration into family life and society following deployment. Increased rates of mild traumatic brain injury (mTBI) and psychological health problems experien ...
