NOVA Scientific, Inc., teamed with the Electronics Group of Oak Ridge National Laboratory, proposes to construct very large area Microchannel Plate neutron detectors. The applications of these much larger format detectors will serve an exceptionally broad range of government agencies from neutron scattering detectors for DOE to nuclear material panel detectors for NNSA, and ultimately to nuclear m ...

The objective of lab-on-chip (LOC) or -TAS is to integrate and perform multiple analytical processes (e.g. sample pretreatment, solution distribution/mixing, separation, detection, etc.) on a microchip platform. So far, most LOC research has been focused on electrophoretic separations. Little has been done on multi-process integration, due mainly to the lack of a robust and miniaturized pump that ...

Due to their vast diversity and as-yet uncultivated status, detecting, characterizing and quantifying microorganisms in natural settings are of grand challenge, and understanding the mechanistic linkages between microbial diversity and ecosystem functioning and their feedback responses to human activities and climate change is even more difficult. There is an urgent need to develop rapid high thro ...

The interactions among different microbial populations in a community play critical roles in determining ecosystem functioning but very little is known about the network interactions in a microbial community due to the lack of appropriate experimental data and computational analytic tools. High-throughput metagenomics technologies can rapidly produce massive data, but one of the greatest challenge ...

Future magnets for Fusion Energy Systems require superconducting cables with improved high critical current carrying capacity at high magnetic fields, 20 Kelvin operation, low AC losses and lower cost. A new method of fabricating a high current cable with 2G HTS tapes has been developed that will improve the engineering current density achievable. Commercial Applications and Other Benefits: Fut ...

The AEgis Technologies Group proposes to develop an innovative real-time thermal solver solution to model hardbody thermal histories. This thermal solver solution will consider the relevant phenomenology associated with MDA targets and other associated objects requiring thermal histories. Modeling of complex objects and advanced features such as model ablation and dynamic surface areas will be co ...

Existing thermal analysis tools for optical signature generation are employed in an off-line manner, and are inadequate for new closed-loop real-time system simulations being pursued by MDA. This STTR project aims to develop and demonstrate an innovative simulation tool for the automatic generation and subsequent computation of reduced thermal models for accurate, real-time analysis of complex 3D ...

The MDA is developing satellite based systems that could benefit from ongoing developments in advanced materials for lithium ion batteries. Unfortunately, the driving applications for much of the new materials research have less abusive operational cycles than the frequent cycling, and sporadic pulse loads to deep discharge, of MDA satellite applications. Physics based models of battery performa ...

Active defects negatively impact the performance of IRFPAs by increasing noise at various levels up to, and including, catastrophic degradation. Evidence indicates that"killer defects"are related to the interaction of open core screw dislocations with impurities that remain after substrate preparation, prior to HgCdTe growth. This impurity diffusion creates a conducting channel that shorts the j ...

For HgCdTe infrared focal plane arrays fabricated on Si substrates, a model has recently been proposed to account for the disparity between the density of failed pixels and the density of dislocations that are present in the HgCdTe junction region. The model distinguishes between active and inactive dislocations and offers a hypothesis that dislocations are active only when they intersect particul ...
