New ORNL software improves neutron spectroscopy data resolution

DOE/Oak Ridge National Laboratory

Neutron spectroscopy is an important tool for studying magnetic and thermoelectric properties in materials. But often the resolution, or the ability of the instrument to see fine details, is too coarse to clearly observe features identifying novel phenomena in new advanced materials. To solve this problem, researchers at Oak Ridge National Laboratory, developed a new super-resolution software, called SRINS, that makes it easier for scientists to better understand materials' dynamical properties using neutron spectroscopy.

Neutrons 'break the ice' for exploring fundamental physics in frozen water

DOE/Oak Ridge National Laboratory

Scientists from Xavier University and Oak Ridge National Laboratory used neutrons to explore the atomic structure of ice, which sometimes features mysterious molecular anomalies in its otherwise crystalline structure. Learning more about these ionic defects could help researchers learn more about similar inconsistencies found in other materials.

BP looks to ORNL, ADIOS to help rein in data

DOE/Oak Ridge National Laboratory
Business Announcement

British Petroleum researchers invited ORNL data scientists to give the company's high-performance computing team a tutorial of the laboratory's ADIOS I/O middleware. ADIOS has helped researchers achieve scientific breakthroughs by providing a simple, flexible way to describe data in their code that may need to be written, read, or processed outside of the running simulation. ORNL researchers Scott Klasky and Norbert Podhorszki demonstrated how it could help the BP team accelerate their science by helping tackle their large, unique seismic datasets.

Getting a Closer Look Inside Biomolecules

DOE/Oak Ridge National Laboratory

Isotope 'labeling' techniques replace specific atoms in a compound with an isotope that can be detected by its neutron count.

Pushing the Precision of Nanoscale Mapping

DOE/Oak Ridge National Laboratory

A popular microscopy tool can give false results about certain materials' properties. Scientists have developed a new quantitative approach to identifying and removing these artifacts. This new technique will provide a clear way to distinguish false motions from the sample's true electromechanical phenomena in materials.

With ADIOS, Summit processes celestial data at scale of massive future telescope

DOE/Oak Ridge National Laboratory
Business Announcement

Researchers cannot collect enough observational data to practice analyzing the huge quantities expected from the Square Kilometre Array, which will be the world's largest radio telescope. Instead, an international team recently used Summit to simulate the SKA's expected output, then used ADIOS to process the simulated data.

GODDESS detector sees the origins of elements

DOE/Oak Ridge National Laboratory

Ancient Greeks imagined that everything in the natural world came from their goddess Physis; her name is the source of the word physics. Present-day nuclear physicists at the Department of Energy's Oak Ridge National Laboratory have created a GODDESS of their own--a detector providing insight into astrophysical nuclear reactions that produce the elements heavier than hydrogen (this lightest of elements was created right after the Big Bang).
