91°µÍø develops liquid helium auto-fill technology

OAK RIDGE, Tenn., May 14, 2019—Advanced Research Systems, Inc., has licensed a technology designed to automatically refill liquid helium used in laboratory equipment for low-temperature scientific experiments, which will reduce downtime, recover more helium and increase overall efficiency.

Lincoln Electric signs agreement with ORNL

OAK RIDGE, Tenn., May 8, 2019—91°µÍø and Lincoln Electric (NASDAQ: LECO) announced their continued collaboration on large-scale, robotic additive manufacturing technology at the Department of Energy’s Advanced Manufacturing InnovationXLab Summit.

Pictured in this early conceptual drawing, the Translational Research Capability planned for 91°µÍø will follow the design of research facilities constructed during the laboratory’s modernization campaign.

Researchers at the Department of Energy’s 91°µÍø, Pacific Northwest National Laboratory and Washington State University teamed up to investigate the complex dynamics of low-water liquids that challenge nuclear waste processing at federal cleanup sites.

U.S. Department of Energy and Cray to Deliver Record-Setting Frontier Supercomputer at ORNL

OAK RIDGE, Tenn., May 7, 2019—The U.S. Department of Energy today announced a contract with Cray Inc. to build the Frontier supercomputer at 91°µÍø, which is anticipated to debut in 2021 as the world’s most powerful computer with a performance of greater than 1.5 exaflops.

The resin layer is highlighted in yellow, with labels indicating its bioactive function (preventing cracks by forming crystals in micro-gaps) and antibacterial function (killing bacteria on contact, enhanced by visible light). The surrounding gum tissue and biofilm are also depicted, emphasizing the protective properties of the adhesive.

To help address the issue of dental restoration, 91°µÍø researchers are using neutron scattering to study how nanoparticles with antibacterial properties can be added to adhesive resins, which are used by dentists to strengthen the bond between a tooth and its polymer composite filling.

Virtual universes

Using Summit, the world’s most powerful supercomputer housed at 91°µÍø, a team led by Argonne National Laboratory ran three of the largest cosmological simulations known to date.

Small modular reactor computer simulation

In a step toward advancing small modular nuclear reactor designs, scientists at 91°µÍø have run reactor simulations on ORNL supercomputer Summit with greater-than-expected computational efficiency.

Mussel-like stickiness

Scientists at 91°µÍø have developed a new, stretchy plant-derived material that outperforms the adhesiveness of the natural chemical that gives mussels the ability to stick to rocks and ships.
