OLCF Helps GE Deliver Next-Generation Gas Turbines

In 2017, US-based General Electric (GE) delivered its newest heavy-duty gas turbine, the 7HA.02, to two power plants in Texas. The installations marked a milestone in natural gas–derived electricity generation, setting new marks in efficiency and emissions for utility-scale turbomachinery.

Purple Power: Synthetic ‘Purple Membranes’ Transform Sunlight to Hydrogen Fuel

Researchers at the U.S. Department of Energy’s Argonne National Laboratory have found a new way to produce solar fuels by developing completely synthetic bionano machinery to harvest light without the need for a living cell.

International Team Reconstructs Nanoscale Virus Features from Correlations of Scattered X-rays

As part of an international research team, Jeff Donatelli, Peter Zwart and Kanupriya Pande of the Center for Advanced Mathematics for Energy Research Applications (CAMERA) at Lawrence Berkeley National Laboratory (Berkeley Lab) contributed key algorithms which helped achieve a goal first proposed more than 40 years ago – using angular correlations of X-ray snapshots from non-crystalline molecules to determine the 3D structure of important biological objects

Exploring the Exotic World of Quarks and Gluons at the Dawn of the Exascale

A new research effort led by theorists at DOE’s Thomas Jefferson National Accelerator Facility (Jefferson Lab) is now preparing for the next big leap forward in their studies thanks to funding under the 2017 SciDAC Awards for Computational Nuclear Physics.

Tracking the Viral Parasites of Giant Viruses over Time

Using metagenome data sets collected over several years in northern freshwater lakes, a team led by researchers at The Ohio State University and the U.S. Department of Energy Joint Genome Institute (DOE JGI), a DOE Office of Science User Facility, uncovered 25 novel sequences of virophages.

Leaning Into the Supercomputing Learning Curve

Recently, 70 scientists — graduate students, computational scientists, and postdoctoral and early-career researchers — attended the fifth annual Argonne Training Program on Extreme-Scale Computing (ATPESC) in St. Charles, Illinois.

Reimagining Hydrogen: A Small Molecule With Large-Scale Ideas

The Department of Energy (DOE) has launched “Hydrogen at Scale,” or H2@Scale, an initiative that explores the potential for wide-scale hydrogen production and utilization in the United States to benefit many sectors of the economy.

Dramatic Flares

Supercomputing aids experiments in sorting out the hidden mechanics of magnetic field reconnection, a key factor in solar storms and fusion energy reactors.

PPPL and General Atomics Team Up to Make TRANSP Code Widely Available

Plasma transport analysis, the study of how plasma particles, heat and momentum drift across magnetic field lines, is a necessary first step for understanding how well fusion reactors are performing. Teams of scientists from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics (GA) have joined forces to bring PPPL’s premier transport code, TRANSP, to beginning users and experts alike.

Summer Intern Jaime Avilés Acosta Studies Materials for Ultra-Fast Particle Detector

Supported by DOE’s Minority Serving Institutions Partnership Program, which provides science and engineering experiences for minority students, the Indiana University graduate spent ten weeks collaborating with mentor Mickey Chiu, a physicist in the sPHENIX collaboration at Brookhaven’s Relativistic Heavy Ion Collider (RHIC).

Forget About It

Inspired by human forgetfulness — how our brains discard unnecessary data to make room for new information — scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in collaboration with Brookhaven National Laboratory and three universities, conducted a recent study that combined supercomputer simulation and X-ray characterization of a material that gradually “forgets.”

Scientists Use Machine Learning to Translate 'Hidden' Information that Reveals Chemistry in Action

New method allows on-the-fly analysis of how catalysts change during reactions, providing crucial information for improving performance.
