Award Data

This project will achieve a mobile application called SleepFit that enables users to track their sleep habits and receive feedback that promotes positive behavior change to improve sleep quality. The SleepFit app will: (1) unobtrusively collect accurate s

There is an increasing need to understand the impacts particles emitted by both natural and human activities have on cloud properties, precipitation and climate. DOE has identified a need to improve the measurement capability of observational platforms, particularly in the Arctic region. One barrier to progress in understanding the interactions of particles and clouds and the importance of cloud c ...

For advanced gas turbines where turbine inlet temperature reaches 2650F and beyond, the current state-of-the-art thermal barrier coating (TBC) systems are not adequate to provide the needed protection for the metallic components of the turbine engine. Thus there is a need to develop new chemistries for TBC systems, consisting of bond coat and top coat, with enhanced durability. We propose to modi ...

Statement of Problem to be Addressed (1-3 sentences): Advances in small satellite and sensor technology are revolutionizing the Earth observation industry, but the development of new raster processing tools to harness this growing stream of nearly real-time data has not kept pace. Storing and processing such data is currently cumbersome or even impossible for many individuals and organizations tha ...

Problem Statement: Real-time analysis and monitoring of networks is crucial for threat detection. Networks are ubiquitous in todays world and can appear in many formats and to name a few we have: communication networks, social networks, and power networks. In many instances it is important to know who the key players are in the network these can be people, computers, or relay stations. One of the ...

Problem Statement: Since the initial development stages of Atomic Force Microscope, AFMs with optical readout have become the center of attraction for researchers in the field. Despite offering high sensitivity and satisfactory performance, the optical setup is bulky and houses sophisticated and costly optical elements and assemblies that are highly sensitive and inconvenient to work with. This li ...

Statement of the problem or situation that is being addressed - typically, one to three sentences. Solid state lighting (SSL) is a fast growing technology, which is starting to replace conventional lighting products such as fluorescent and incandescent bulbs. While the current efficiency of some commercial SSL products has surpassed those of most traditional lighting, it is still far below what th ...

Statement of the problem or situation that is being addressed: In this project, we propose to develop a high repetition rate, 100 nm ultrafast source for spectroscopy, and imaging using Ytterbium laser technology for hollow core fiber resonant enhanced 5th harmonic generation. Currently, there are no commercial or scientific sources with the combination of high (100kHz 1MHz) repetition rate, and ...

Statement of the problem or situation that is being addressed: In this project, we propose to develop waveguides specific to high harmonic generation, that are more efficient than standard HHG waveguides, can handle pressures in excess of > 30 bar, minimize losses for wavelengths > 1 m, and can be manufactured with ultrafast micromachining. Current waveguides using hollow core fused silica are a g ...

Statement of the Problem or Situation that is being addressed Lithium-ion batteries are considered candidates for large-scale energy storage mainly because of their high energy density and flexibility. However, current lithium-ion battery technology does not meet the critical requirements in terms of safety, ultra-long cycle life and shelf life, low cost, and improved energy density. Element Sulfu ...
