    An ORNL-led team conducts moisture durability simulations on construction materials, which will add real-world data to a new system developed to help builders and home designers make informed decisions.

Energy—Quantum computing efficiency 

New research from Oak Ridge National Laboratory indicates that quantum computers will use dramatically less energy than current supercomputers, which could lead to cost savings for computing equipment manufacturers and data centers. “High-performance computers with thousands of processors currently use lots of power to perform complex scientific calculations,” ORNL’s Travis Humble said. Using a sophisticated simulation technique, the team compared the expected energy usage of a quantum processor that uses quantum physics to the energy usage of a conventional processor found in today’s modern supercomputers. “Along with an unprecedented ability to solve big problems, we found that quantum computers have the potential to reduce energy usage by more than one million kilowatt hours,” he said. The team presented their results during the IEEE Rebooting Computing conference. [Contact: Sara Shoemaker, (865) 576-9219; shoemakerms@ornl.gov]

Materials—Supertough bioplastic

A novel method developed at Oak Ridge National Laboratory creates supertough renewable plastic with improved manufacturability. Working with polylactic acid, a biobased plastic often used in packaging, textiles, biomedical implants and 3D printing, the research team added tiny amounts of silicon-based materials called silanes to design a new polymer. “Our fast, scalable approach makes a new form of PLA that is 10 times tougher without sacrificing strength or stiffness,” said ORNL’s Soydan Ozcan. “This could broaden applications where polymer toughness is critical.” The research team detailed the underlying chemical reactions in ACS Sustainable Chemistry & Engineering. The team plans to tailor the new polymer for additive manufacturing and packaging. [Contact: Kim Askey, (865) 576-2841; askeyka@ornl.gov]

Buildings—The right stuff

A new system being developed at Oak Ridge National Laboratory will help builders and home designers select the best construction materials for long-term moisture durability. “It has become challenging to make informed decisions because of modern building code requirements and new products and materials hitting the market,” ORNL’s Philip Boudreaux said. Researchers will couple input from structural and materials experts with data gleaned from running approximately 800,000 building envelope simulations on ORNL’s Titan supercomputer, accounting for choice of materials, climate, orientation, air tightness and indoor conditions. “The resulting comprehensive database will be accessible via a user-friendly web-based tool, which is undergoing beta testing,” Boudreaux said. ORNL detailed their method in the Journal of Building Physics. The team will further fine-tune the system with data from real-world moisture durability simulations performed on wall assemblies using the lab’s Heat, Air and Moisture Penetration Test Chambers.

In a First, Tiny Diamond Anvils Trigger Chemical Reactions by Squeezing

Menlo Park, Calif. --Scientists have turned the smallest possible bits of diamond and other super-hard specks into "molecular anvils" that squeeze and twist molecules until chemical bonds break and atoms exchange electrons. These are the first such chemical reactions triggered by mechanical pressure alone, and researchers say the method offers a new way to do chemistry at the molecular level that is greener, more efficient and much more precise.

Berkeley Lab "Minimalist Machine Learning" Algorithms Analyze Images From Very Little Data

Berkeley Lab mathematicians have developed a new approach to machine learning aimed at experimental imaging data. Rather than relying on the tens or hundreds of thousands of images used by typical machine learning methods, this new approach "learns" much more quickly and requires far fewer images.

Organic polymer solar cells show potential to provide solar power to remote microwatt sensors, wearable technology and the Wi-Fi-connected appliances constituting the "internet of things." While PSCs cannot match the durability or efficiency of inorganic solar cells, the potential to mass-produce nontoxic, disposable solar panels using roll-to-roll production makes them attractive for additional applications. In this week's Journal of Renewable and Sustainable Energy, researchers review the latest advances and remaining challenges in PSC technology.

45-Year-Old Telescope Gets a Makeover to Demystify Dark Energy

Forty-five years ago this month, a telescope tucked inside a 14-story, 500-ton dome atop a mile-high peak in Arizona took in the night sky for the first time and recorded its observations on glass photographic plates. Today, the dome closes on the previous science chapters of the 4-meter Nicholas U. Mayall Telescope and starts preparing for its new role in creating the largest 3-D map of the universe. This map could help determine why the universe is expanding at faster and faster rates, driven by an unknown force called dark energy.
