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 ...

This project will develop plasmonic films that perform the dual functions of optical filtering and electrical conduction for solar-blind ultraviolet radiation (UV) detectors. Two types of plasmonic structures will be investigated, namely nano-hole arrays in an aluminum film atop UV radiation detecting semiconductors. These two similar plasmonic structures support different types of surface plasm ...

This STTR Phase I project will develop a novel multifunctional coating to combat a wide range of threats in a variety of complex situations for the warfighter. Military combat uniforms currently use NYCO fabrics (Nylon/cotton 50/50). The US Army is seeking new coating technologies that will impart multifunctional properties such as antistatic, conductive, flame resistance, improved abrasion resis ...

The enormous effort devoted to the data acquisition, signal processing, and automatic recognition of stationary targets has resulted in a generation of synthetic aperture radar (SAR) systems that are meeting the challenge of real-world conditions. However, in a practical battlefield, moving targets may pose a more severe threat than stationary targets. Many high value targets are only vulnerable w ...

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 ...

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 ...

The overall goal of this proposed Army STTR is to demonstrate low-cost, non-destructive methodologies for non-agglomerating drying of anisotropic nanomaterials. NanoSonic and Virginia Tech will work in tandem to demonstrate novel approaches involving both high performance coatings and CO2 processing that facilitate gentle, simultaneous drying and exfoliation of nanoparticles, preventing agglomera ...

A platform for rapid production of novel sensors is in great demand to protect and aid the Warfighter in today’s ever changing defense landscape. Biosensors are one possible sensing solution as they harness nature’s immense diversity and adaptability to detect desired targets. By coupling synthetic biology with nature’s capabilities, any small molecule can be detected. This project focuses o ...

In resource limited settings, rapid and accurate diagnosis of infections is critical for managing potential exposures to highly virulent pathogens,whether occurring from an act of bioterrorism or a natural event. This is especially important for hard to detect intracellular bacterial andalphavirus infections, that overlap symptomatically and often treated empirically due to a lack of reliable and ...
