A new high-value product zero calorie sweetener L-arabinose has been identified because it may be produced from the D-xylose-rich aqueous biomass intermediate stream at low costs. L-arabinose is an FDA approved healthy sweetener with dual functions as a sucrase inhibitor and a prebiotic, but its current high price ($30/kg) prevents wide use. The co-production of high-value products such as L-ara ...

Summary: In the DOE SBIR topic Advanced Digital Network Technologies and Middleware Services, the Office of Advanced Scientific Computing Research seeks grant applications for developments in advanced optical network technologies that enable DOE scientists to communicate with peers, and collect/process data at Gbps data-rates. Providing Gbps wireless connection is a challenge in last-mile networks ...

Statement of Problem. A series of national innovation reports, surveys, case studies, and specifically results from recent small to medium-sized enterprise (SME) pilots have uncovered inadequate adoption of HPC and modeling and simulation technology in manufacturing. As a direct result, much emphasis is now being placed on the development of applications (APPs) for very specific domains and use ca ...

Statement of the problem or situation that is being addressed. Chemical sensitive imaging of heterogeneous materials and biological cells requires a sensitive, high spatial resolution microscopy method based on vibrational resonances that is capable of performing in situ spectroscopy with both frequency and time resolution. Statement of how this problem or situation is being addressed. In this SBI ...

Statement of the Problem Isotopologues are a critical tool in monitoring plant hydrobiogeochemical and microbial systems and processes. The most abundant elements utilized and exchanged by plants, microbes and ecosystems are carbon (C), hydrogen (H), oxygen (O) and nitrogen (N), all of which have naturally occurring stable isotope forms that can be used as natural tracers for understanding and int ...

Statement of the problem or situation that is being addressed. This proposed research project responds directly to the need of a high-efficiency continuous-wave microwave source at a frequency of 1.497 GHz delivering at least 8kW of power. This research will provide a klystron with an overall efficiency of 82% and a high degree of backwards compatibility to allow its use as a replacement for klys ...

Problem being solved: Research is increasingly trying to push the boundaries with respect to observing rare elemental isotopes encountered as a result of highly energetic cosmic events. These rare elements can be produced through naturally through events such as supernovae, but prove problematic to synthesize and observe in controlled laboratory settings. Rare isotopes can be produced through nuc ...

This project will create a new category of advanced all-Silicon Carbide power inverters for use in energy storage in the medium-voltage range and > 100 kW ratings. A design showing a significant increase in circuit efficiency, cost reduction, an increase in power density, and a reduction in thermal management requirements over the existing Silicon power inverters will eliminate significant waste o ...

Battery storage systems are the backbone of the future gird systems. These systems provide distributed energy storage capabilities for smoothening the load profile and coping with generation and load power fluctuations. By incorporating these resources into the electrical grid, voltage stability and overall reliability of the grid will improve. Furthermore, these resources compensate for fluctuati ...

Reducing the size, weight, and increasing the efficiency of electric vehicle traction power inverters requires the development of novel high-voltage, high current silicon carbide high-speed rectifiers, since the existing silicon technology is severely limited in terms of operating temperature, frequency and energy efficiency. However, the non-optimized device and manufacturing technology currently ...
