Quantifying atmospheric aerosol, clouds and precipitation processes are critical needs for understanding and interpreting Earth’s changing energy budget, is a DOE objective, and is of broader benefit to the public. Specifically, the formation of ice in the atmosphere depends on the nature and abundance of ice nucleating particles, and has major implications for precipitation and cloud interactio ...

Currently the chemical composition of atmospheric particulate matter is measured either by off-line analyses of time-integrated filter samples, or by in-situ instruments requiring near-constant operator oversight. These measurement approaches result in sparse or limited data coverage. Despite the critical role of composition on the health and environmental impacts of particulate matter, there exis ...

The transmission loss (TL) observed by sonar operators can differ significantly from that predicted by Navy models. The long-term objective of the proposed work is to understand why these differences occur and improve the target detection predictive capability of the models. Our approach in Phase I is to analyze bistatic sonar data collected on Navy assets. We will examine both cases with model/da ...

Data generated by external sources needs to be consolidated and processed to derive new training scenarios and to recommend new training objectives and measures of performance. The main technical challenges this solution will address are: data from diverse sources must be pre-processed (i.e., validated, cleaned, synchronized) and loaded into a data warehouse; the central data warehouse must have a ...

GaN power semiconductors offer a technological breakthrough for improving the performance of power electronics including power density, conversion efficiency, and reliability of power converters. These are the three most critical requirements for military, aerospace and many commercial applications. In this STTR program, Qrona Technologies will collaborate with the University of Central Florida to ...

TrueNano, Inc. will in collaboration with the University of Colorado and industry partners, develop a novel single-wafer, high-throughput hot filament CDV reactor for the growth of high quality silicon carbide (SiC) epitaxial layers, suitable for the next generation of power electronic devices and systems. This includes the design and simulation of the reactor, the development of a throughput mode ...

Friction stir welding (FSW) is an attractive joining method where high strength low porosity welds can be attained. However, the high temperatures and forces required for welding high strength materials like steel require the use of exotic tools. Cubic boron nitride (cBN)-based tools offer attractive tool wear characteristics in steels, but are very costly. Conversely, refractory metal alloys are ...

To meet Navy needs for high performance and safe lithium ion (Li-ion) batteries for naval aircraft, ADA Technologies Inc. (ADA) and its university collaborator propose to optimize and transfer a highly tunable, high performance and safe, block copolymer derived nanoporous separator. The innovative strategy provides a powerful tool to allow exquisite tuning of performance and safety features of the ...

The proposed program will develop dielectrics for dc superconducting power transmission cables that are cooled with cryogenic helium gas. The Dielectrics will be sealed again helium gas penetration and allow for an operating voltage of 12 kV in a pressure of 2 MPa at 50 K. The dielectrics will be designed for use with all helium facing components of power transmission systems based on CORC cables. ...

Neutron scattering is one of the most useful methods of studying the structure and dynamics of matter. These methods require large installations at national laboratories, such as Oak Ridge National Laboratory (ORNL), National Institute of Standards and Technology (NIST) and other facilities constructed or planned in the US and around the world. These facilities serve a large and diverse community ...
