Peer-Reviewed Publication

Oak Ridge National Laboratory aids St. Jude's brain development research with software to speed processing of microscopy images; a bottleneck in the process to breakdown lignin for use in biofuels may occur at the plant cell wall's surface; predicting how ecosystems respond to environmental change could become more precise through new process sensitivity index method; through "quantum mechanical squeezing," researchers have conceptually designed a new method to increase the resolution of atomic force microscopy.

Predictive power

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

The Consortium for Advanced Simulation of Light Water Reactors carried out the largest time-dependent simulation of a nuclear reactor ever to support Tennessee Valley Authority and Westinghouse Electric Company during the startup of Watts Bar Unit 2, the first new US nuclear reactor in 20 years. The simulation was carried out primarily on Oak Ridge Leadership Computing Facility resources.

Built from the bottom up, nanoribbons pave the way to 'on-off' states for graphene

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

A new way to grow narrow ribbons of graphene, a lightweight and strong structure of single-atom-thick carbon atoms linked into hexagons, may address a shortcoming that has prevented the material from achieving its full potential in electronic applications. Graphene nanoribbons, mere billionths of a meter wide, exhibit different electronic properties than two-dimensional sheets of the material. 'Confinement changes graphene's behavior,' said An-Ping Li, a physicist at the Department of Energy's Oak Ridge National Laboratory.

A seismic mapping milestone

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Using advanced modeling and simulation, seismic data generated by earthquakes, and one of the world's fastest supercomputers, a team led by Jeroen Tromp of Princeton University is creating a detailed 3-D picture of Earth's interior. Currently, the team is focused on imaging the entire globe from the surface to the core-mantle boundary, a depth of 1,800 miles.

Researchers shoot for success with simulations of laser pulse-material interactions

Two-dimensional MXene materials get their close-up

DOE/Oak Ridge National Laboratory

Researchers have long sought electrically conductive materials for economical energy-storage devices. Two-dimensional (2D) ceramics called MXenes are contenders. ORNL scientists using state-of-the-art scanning transmission electron microscopy provided the first direct evidence of the atomic-defect configurations in a titanium-carbide MXene synthesized at Drexel University. Published in ACS Nano, a journal of the American Chemical Society, the study coupled atomic-scale characterization and electrical property measurements with theory-based simulation.

Nidia Gallego: Carbon scientist is as versatile as the element she studies

DOE/Oak Ridge National Laboratory

At the Department of Energy's Oak Ridge National Laboratory, Nidia Gallego develops carbon materials for energy technologies and space exploration. She investigates the physical and chemical properties of carbon in diverse forms -- including fiber, composites and foam. 'Carbon is a single element that can be many things,' Gallego said. 'It can be hard like diamond, soft like graphite or amorphous like activated carbon. Its material properties depend on how carbon atoms bond with each other.'
