The Department of Energy (DOE) requires the demonstration of bimetallic corrosion-resistant surfaces for structural and cooling components used in molten-salt nuclear-reactor systems. Proposed coating materials must survive thermo-mechanical loading (e.g., no flaking or spalling) during exposure to the high-temperature conditions encountered during reactor operation and maintain metallurgical stab ...

Coarse mode aerosol are an understudied but potentially important component of urban aerosols that affect climate and human health. They are highly relevant to DOE’s interest in improving understanding and resiliency related to climate change impacts on urban areas. Coarse mode aerosol can vary spatially and temporally over urban landscapes due to the large range of coarse mode aerosol emission ...

Current semiconductor device simulation software adopts Fourier’s law to perform the thermal transport modeling. However, Fourier’s law will become invalid at micro/nano-scale, which can cause a large discrepancy in the thermal and electrical performance between the simulation results and the actual application. To improve the current state-of-the-art, a new semiconductor device simulation sof ...

Air quality data from top-of-the-line platforms, such as satellites, are difficult to obtain without a high- level of technical knowledge. For this reason, local air quality patterns and trends are often inaccessible to disadvantaged communities (DACs). Many technologies that will be used for deep decarbonization of industrial and power facilities have the added co-benefit of reducing non-CO2 poll ...

C53-22c-271119Meeting climate-stabilizing energy transition goals requires using hybrid-energy CO2 capture systems like Direct Air Capture (DAC) to remove billions of tonnes of CO2 from the atmosphere. Deploying this capacity will be difficult because it is complex and energy intensive infrastructure, and there must also be buy- in from communities living in locations best suited for it. The chall ...

C53-02a-271164Research and development advances in novel nuclear reactor design for power production depend on computer simulations to validate efficiency and safety. Most existing simulation co des require training and expertise and have restrictive licenses that make them hard to acquire and use. One promising open-source code is easy to use and can spread its calculations across many computers, ...

C53-02b-271168The software used in High Performance Computing (HPC) and ArtificialIntelligence/MachineLearning (AI/ML) workloads is increasingly complex to maintain, install, and optimize. More problematic is the poor performance portability of applications between platforms, forcing site-specific re-engineering of codes. Existing solutions to deployment of AI/ML work?ows on commercial cloud envir ...

C53-31a-271169Significant technical innovations are needed to improve the economics of plastic recycling. Plastic recycling rates in the United States have been stagnant for more than a decade: less than 10% of plastics are currently recycled, and only 5.5% of polyurethane plastics are recycled. Plastics have become a major contributor to global warming, as emissions from global plastics productio ...

C49-18a-271181The need for high-temperature furnaces for neutron scattering experiments has been increasing considerably. One of the major limiting factors of these furnaces is the cooling rate. Currently, the vacuum furnace relies on radiation to dissipate heat and takes at least 2 hours to cool the furnace low enough to safely open for a sample change. This results in significant limitations of ...
