Additive Manufacturing (AM), where three-dimensional (3D) objects are created from a digital model by depositing and fusing successive layers of material, provides the ability to produce low-volume, customized products with complex geometries relatively quickly at a moderate cost. However, AM processes sometimes fail to produce acceptable parts, due to either geometric in- accuracy (e.g., shrinkag ...

In this phase-I proposal, the effect of terrestrial cosmic rays on the failure rate of commercial 1200V SiC power MOSFETs will be studied. The goal of the study is to quantify the appropriate breakdown voltage de-rating needed for SiC MOSFETs subject to cosmic rays. The failure rate of SiC power MOSFETs as a function of the reverse blocking voltage will be determined and compared to failure rate o ...

The objective of this technology transfer effort is to leverage technology developed at Savannah River National Laboratory (SRNL) to develop a portable proportional counter (PC) for neutron detection. NanoTechLabs Inc. (NTL) will develop a portable proportional counter for neutron detection utilizing nanostructured field emitters. Unlike traditional proportional counters, which are typically arran ...

Current and next-generation power systems require power devices that operate at high voltages and high frequencies beyond the reliable operating limit of the present silicon- and silicon carbide-based power devices. The material properties of AlN permit power devices to operate at these extremes, promoting device shrinkage for automotive applications as well faster switching and more efficient pow ...

Deep borehole disposal of high level nuclear waste has been acknowledged by most experts as the best and safest method to permanently dispose the large volumes/ tons of such waste that have been generated (military and civilian) and surface stored over many decades at various sites around the country. Surface storage of such materials is not ideal. The cost of the required wells (drilling and com ...

DESCRIPTION (provided by applicant): The objective of this STTR proposal is to develop a 2-D diffusion point-of-care assay (POC) for B-type natriuretic peptide (BNP). The primary goal of the proposed work is to create a test format that will allow patientswith chronic heart failure to quantitatively self-monitor serum levels of BNP. Determination of baseline level of BNP and changes in this level ...

DESCRIPTION provided by applicant Nearly percent of death and disease worldwide is linked to environmental factors WHO therefore it is critical that the general public has basic understanding of how the environment affects their health and how they might protect themselves against environmental exposures Unfortunately environmental health content is typically covered on a very ...

? DESCRIPTION (provided by applicant): NMR is probably the most powerful and widely used analytical technique for structure determination and function elucidation of molecules of all types, but it suffers from low sensitivity, particularly for insoluble biological macromolecules. Dynamic Nuclear Polarization (DNP) with Magic Angle Spinning (MAS) has recently demonstrated S/N gains exceeding t ...
