Climate – Bridging human impacts

A new integrated computational model reduces uncertainty in climate predictions by bridging Earth systems with energy and economic models and large-scale human impact data. Co-developed by Oak Ridge National Laboratory, the novel integrated Earth system model, or iESM, leverages the power of supercomputers, including ORNL’s Titan, to couple biospheric feedbacks from oceans, atmosphere and land with human activity, such as greenhouse gas emissions, agriculture and land use. “The resulting model provides comprehensive predictions of projected climate outcomes, eliminating important sources of uncertainty from those predictions,” ORNL’s Peter Thornton said. The ORNL-led team detailed the modeling results in Nature Climate Change. They will continue using Titan to further develop, evaluate and apply iESM, delivering new knowledge and capabilities to the broader climate science community.

Computing – Data-driven healthcare for veterans

Oak Ridge National Laboratory has partnered with the Department of Veterans Affairs to develop methods and algorithms to mine the VA’s health data more efficiently. The resulting novel, secure platform promises to improve the health and wellbeing of millions of veterans through better understanding of underlying causes of diseases and conditions, hereditary factors and health history. “The transfer of such large volumes of data, and its continued security, requires ORNL’s platform to be thoroughly vetted and tested before it is made available to researchers,” said Edmon Begoli who leads the lab’s involvement in the Million Veterans Program-Computational Health Analytics for Medical Precision to Improve Outcomes Now, or MVP-CHAMPION.

Neutrons – Beating the clock

Using neutron scattering at Oak Ridge National Laboratory, a research team captured a time-sensitive phenomenon to prove that the entropy, or randomness, of atoms in a metallic glass when exposed to intense heat is linked to how atoms self-configure versus their vibration. The large neutron flux of ORNL’s Wide Angular Range Chopper Spectrometer continuously recorded changes in the sample’s vibrations as the temperature slowly increased—a technique not possible a decade ago. “It’s only thanks to the incredibly intense neutron beams available at ORNL that we could do this experiment and put to rest a decades-old, much-debated theory that had never been tested,” said Hillary L. Smith from California Institute of Technology who led the paper published in Nature Physics. Understanding the material’s behavior could help in developing better quality metallic glass alloys.

Buildings – Airtight savings

A new tool developed at Oak Ridge National Laboratory can help homeowners and builders calculate energy loss when air leaks through a building’s envelope, the physical barrier separating the interior and exterior. Starting with specific building metrics, the calculator analyzes multizone airflow and ventilation and then determines the associated energy loss through a whole building energy simulation tool. “Air leaks are responsible for over four percent of all energy used in the United States,” ORNL’s Som Shrestha said. “This energy-savings calculator can demonstrate the benefit of constructing airtight buildings.” The free, web-based tool was developed in conjunction with the Air Barrier Association of America and the National Institute of Science and Technology.

Manufacturing – Tailoring performance

A new manufacturing method created by Oak Ridge National Laboratory and Rice University combines 3D printing with traditional casting to produce damage-tolerant components composed of multiple materials. Composite components made by pouring an aluminum alloy over a printed steel lattice showed an order of magnitude greater damage tolerance than aluminum alone. The process, published in Materials and Design, was developed for potential automotive and other applications where thermal and mechanical properties must be optimized simultaneously. “This scalable processing strategy can be used to fulfill specific component functions, giving materials designers unprecedented control over both microstructure and material properties,” said ORNL’s Amit Shyam.

A New Optimization Model Could Bring Higher Solar-Power Integration

With numerous installations of solar power systems for residential homes at or near the distribution site, there is a challenge to balance supply and demand to make these intermittent energy sources reliable. Demand response is one promising way to increase operational flexibility and energy efficiency, and researchers in Malaysia have incorporated DR scenarios in case studies based on 100 urban low-voltage network samples to learn more. They report their findings in this week's Journal of Renewable and Sustainable Energy.
