The objective of the work described in this proposal is to aid in the advancement of Mo-Si-B alloys for use in high temperature applications such as hot gas stream components in turbine engines. Such alloys are being characterized for their monotonic tensile properties in tension and compression as well for their creep resistance. Likewise, multiphase Mo-Si-B alloys have been studied in terms of m ...

Marine mammals like bottlenose dolphins are maintained by US Navy's Marine Mammal Program to protect harbors and detect underwater mines. The maintenance and betterment of health of these dolphins in captivity is a priority in order to improve the fitness and readiness of these animals for defense missions. Accacia International proposes to develop probiotic pharmaceuticals to treat and preve ...

Physical Sciences Inc. (PSI) and their academic partner, West Virginia University (WVU), are pleased to propose a uniquely innovative approach to measuring the three-dimensional air wake velocity field behind ship structures and towers. The velocity data is needed to support the validation of CFD models that will ultimately be used to provide sufficient safety margins for ship aircraft operations ...

Physical Sciences Inc. (PSI), in collaboration with Sandia National Laboratories, proposes to develop a high energy density (HED) power source based on the principles of thermophotovoltaics (TPV). The core technology of the HED power source is a novel high-temperature, spectrally-selective metamaterial emitter with a tailored emission spectrum matched to the external quantum efficiency spectrum of ...

Thermophotovoltaic (TPV) energy conversion produces electrical power from heat energy using, in its most basic form, a thermal emitter and a photovoltaic converter. Since these systems typically have no or few moving parts, they provide a long term maintenance-free power generation. Key factors affecting performance include matching the emitter spectrum more precisely to the conversion characteris ...

As strontium and other alkaline-earth metals become increasingly attractive for ultracold-atom applications, there is a growing need to develop compact, robust systems for cooling, trapping, and studying these elements. In this proposal, ColdQuanta will team with Dr. Jun Ye at JILA and the University of Colorado at Boulder to develop a portable, turn-key system that can produce, utilize, and optic ...

Wearable human state monitors must be mechanically invisible to greatest degree possible, to maximize comfort, wearability, hygiene and signal quality. These device attributes are aligned with the goal of closely coupling devices to the body for best-quality signal capture and continuous health monitoring by seamlessly integrating with the body, under clothing and gear. They must be robust to dyna ...

Green laser sources are important in advanced naval mine detection as this wavelength has good penetration though seawater. Mine detection programs such as the Coastal Battlefield Reconnaissance and Analysis (COBRA) system and the Airborne Laser Mine Detection System (ALMDS) currently use frequency-doubled 1-µm lasers as the laser source. The generation of green laser light via frequency doubling ...

The focus of our Intelligence and Intuition for Enhanced Decision Making (I2EDM) Phase 1 research is to provide efficient and timely automated production and dissemination of information products in support of doctrinal Decision Points for the Company and below in austere environments. Operating in the Cloud, I2EDM will continuously fuse tactical information with human intuition and experience to ...

This project is focused on the development of a new generation of GaN-based transistors with breakdown voltages in excess of 1kV that can be used in the demonstration of power amplifiers operating at 1 GHz with power added efficiencies in excess of 90%. To achieve this performance, this project will develop new approaches to increase the breakdown voltage of GaN high electron mobility transistors, ...
