Study Yields New Knowledge About Materials for Ultrasound and Other Applications

Scientists at the Department of Energy’s Oak Ridge National Laboratory and their research partners have used neutron scattering to discover the key to piezoelectric excellence in the newer materials, which are called relaxor-based ferroelectrics.

ORNL Neutron Science Facilities Welcome 20,000th User

In August, the High Flux Isotope Reactor and the Spallation Neutron Source—both U.S. Department of Energy Office of Science User Facilities at DOE’s Oak Ridge National Laboratory—reached a milestone with the arrival of Irina Nesmelova, the facilities’ 20,000th user.

Unlocking Potential of 3D Printed Rocket Parts with Neutrons

NASA engineers used the Neutron Residual Stress Mapping Facility at Oak Ridge National Laboratory’s High Flux Isotope Reactor to study residual stress in additive manufactured materials which could significantly reduce cost and schedule of flight hardware component manufacture and qualify the materials for flight.

Jefferson Lab Becomes an Intel® Parallel Computing Center and Deploys Newest Parallel Computing Cluster

Work on computing the behaviors of the smallest bits of matter in the universe at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has just gotten a nod from Intel®, as the laboratory becomes the newest Intel® Parallel Computing Center.

Complex materials can self-organize into circuits, may form basis for multifunction chips

Researchers studying the behavior of nanoscale materials at Oak Ridge National Laboratory have shown that a single crystal complex oxide material can act like a multi-component electrical circuit that could advance microprocessors beyond today’s silicon-based chips.

Dianne Bull Ezell: Learning at Every Opportunity

As an R&D engineer in the Electro-Mechanical Systems group, studying system integration at Oak Ridge National Lab, Ezell is an example and mentor for the next generation of engineers.

Developing Scientific Computing Capabilities for the Workforce of Tomorrow

This summer's Scientific Computing 102 internship prepared college students for the big data challenges facing researchers in science, technology, engineering, and mathematics (STEM).

PPPL Researchers Successfully Test New Device that Analyzes the Surfaces of Tokamak Components within a Vacuum

Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have successfully tested a new device that will lead to a better understanding of the interactions between ultrahot plasma contained within fusion facilities and the materials inside those facilities.

Two Protein Studies Discover Molecular Secrets to Recycling Carbon and Healing Cells

Researchers at the U.S. Department of Energy’s (DOE's) Argonne National Laboratory have mapped out two very different types of protein. One helps soil bacteria digest carbon compounds; the other protects cells from the effects of harmful molecules.

Electron Beam Microscope Directly Writes Nanoscale Features in Liquid with Metal Ink

Scientists at the Department of Energy’s Oak Ridge National Laboratory are the first to harness a scanning transmission electron microscope (STEM) to directly write tiny patterns in metallic “ink,” forming features in liquid that are finer than half the width of a human hair.

In Search of a Signal

A research team from Argonne National Laboratory and McGill University is performing simulations at the Argonne Leadership Computing Facility (ALCF), a U.S. Department of Energy (DOE) Office of Science User Facility, to construct cosmological maps that will help improve the analysis of data from two of the world’s most powerful astronomical instruments, the Dark Energy Survey and the South Pole Telescope.

How Fungi Help Trees Tolerate Drought

An international team of researchers found specific adaptations in the C. geophilum transcriptome – the set of its messenger RNA molecules that reflects actual biochemical activity by the fungus – that could help their hosts be more resistant to drought stress, a finding that could be useful in developing more plant feedstocks for bioenergy amidst the changing climate.
