Liquid-metal coolants are one of the most promising solutions for the challenges of advanced high temperature nuclear reactor systems.They optimize heat transfer, neutronics, safety, and compactness of the reactor systems.Molten lead and lead-bismuth eutectic (LBE) are the primary coolant candidates due to their unique thermo-mechanical and neutronics properties.However, they are highly corrosive ...

High performance supercritical carbon dioxide (S-CO2) turbo-expanders/power turbines will provide significant increases in efficiency and compactness, while reducing greenhouse gases and water usage. This project will develop a permanent magnet biased magnetic bearing system, that is actively cooled to the 550°C maximum operating temperature limit of permanent magnets. The magnetic bearing test e ...

The state of computational chemistry software is in fragmented. Excellent and trusted academic software, which contains advanced molecular simulation code, exists but is seldom used in industry. Industrial software is closed, expensive and has not proven to be as good a foundation as academic software for developing advanced methods where machine learning can be used to design new molecules and ma ...

Methods for interconversion between cell types (cellular reprogramming) are currently discovered through resource intensive trial and error. Experiments may test a multitude of transcription factors to identify correct combinations that influence cell fate. In addition, reprogramming approaches commonly use stem cell intermediates such as induced pluripotent stem cells (iPSCs), which are generated ...

State of the art yttria stabilized zirconia (YSZ) based thermal barrier coatings (TBCs) are typically limited to maximum use temperatures of 1200-1300C. A thermal barrier coating (TBC) with a 1500C temperature capability would be a major gas turbine materials breakthrough. New coatings with a 200C temperature advantage can be used by the gas turbine industry to significantly increase turbine effi ...

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 ...

The DOE Systems Biology Knowledgebase (Kbase) was envisioned to provide a framework to support modeling of dynamic cellular processes of microorganisms, plants and metacommunities. The Kbase will provide the tools and data to permit rapid iteration of experiments that draw on a variety of data types and allow end-users to infer how cells and communities respond to natural or induced perturbations, ...

We shall investigate, implement and demonstrate MAVIS, a 3D vision system incorporating robust Real-Time SFM for SMAV application scenarios. Automatic pose determination and extraction of 3D structure of the environment are critical to autonomous navigation and obstacle avoidance of SMAVs in constrained and crowded environments. Extracting such state information under various constraints (low qual ...
