Development of hypersonic aircraft and weapon systems has become a critical focus for the Department of Defense to maintain global strike and projection of force capabilities. Despite decades of research, traditional computational fluid dynamics (CFD) methods are either incapable of adequately predicting complex features in hypersonic flows or too expensive to be of practical use for vehicle desig ...

As outsourced microelectronic manufacturing grows, the safety and security of U.S. consumers becomes increasingly threatened by potential counterfeit electronics. Current counterfeit inspection techniques are labor intensive, time consuming, and impractical to use by field agents located on remote sites, away from major facilities, and with limited expertise. The proposed work, Fast and Accurate D ...

Check point screening of passengers is key to mitigating threats to aviation. This essential mission must be performed while expediting traffic flow and without discrimination to elderly or disabled travelers.The screening mission is challenged by the inaccessibility of Advanced Imaging Technology (AIT) and metal detector walk-through portals to travelers with mobility disabilities and certain med ...

Yotta Navigation proposes to develop a Mass Fatality Tracking System (MFTS) tagging device to aid search and recovery teams in locating victim remains during a Mass Casualty Incident (MCI). The Phase II effort will provide the DHS stakeholders with two sets of prototype Yotta Tag devices, complete with the supporting cloud-based database and User Interface (UI) applications. The first set of 10 pr ...

C53-14b-271071The increasing data rates in conventional and scanning transmission electron microscopy, afforded by the developments of faster detectors and novel in-situ methods, requires automation of post- acquisition data analysis and, ideally, identification of regions of interest during experimental data acquisition. The overarching objective of this program is to leverage a suite of cutting- ...

C53-33b-271095Recently developed precision timing detector technology based on silicon Low Gain Avalanche Diode (LGAD) although exhibiting excellent timing performance, cannot attain 10µm position resolution needed for advanced 4D detectors. New small-pitch detector solutions are being developed which necessitates development of complimentary Application Specific Integrated Circuits (ASICs) and r ...

C53-26a-271115The extent, persistence and microphysical properties of clouds influence Earth’s climate and hydrologic cycles. A critical factor affecting cloud characteristics is the concentration of airborne particles around which cloud droplets form. A significant contributor to these particles is atmospheric nucleation, which injects large numbers of small particles into the atmosphere. Once ...

C53-13a-271127Electron microscopes have been widely used by material scientists, biologists, and industrial scientists to study the composition and chemical structure of materials with high spatial resolution. Aberration-corrected instruments can image individual defects and interfaces at atomic resolution, and continued advances in electron energy-loss spectroscopy (EELS) have made elemental anal ...

C53-18c-271136The lack of affordable large-scale batteries makes electric vehicles too expensive for most consumers and makes renewable energy storage financially impractical for almost everyone. Although Li-ion battery prices have fallen over the past three decades, they are threatening to rise higher as Li-ion production for electric vehicles is predicted to consume the world’s high-grade coba ...

C53-27a-271143Transformative advances in cryogenic electron microscopy (cryo-EM) have expanded our ability to visualize cellular and biomolecular structure, often at atomic resolution. However, a significant hurdle for achieving the full potential of cryo-EM, including work performed at facilities associated with DOE, involves difficulties with sample preparation. Reliably producing vitrified ultr ...
