A noise filter developed at Oak Ridge National Laboratory could spell doom for unwanted EMI in thermocouple devices.
Electromagnetic interference, a nuisance to electronic devices used in hundreds of applications that include biomedical, automobiles, manufacturing, satellites and space, could be a non-issue because of a noise filter invented at Oak Ridge National Laboratory. Researcher Roger Kis...
This map of New York City shows how many people walk to work each morning. The resolution is block group level.

Simply widening sidewalks and increasing the bike lanes network can boost the number of New York City commuters who choose to take advantage of an option that’s healthy for people and the environment, according to Husain Aziz of Oak Ridge National Laboratory’s Urban Dynamics Insti...

ORNL researcher and University of Tennessee Bredesen Center for Interdisciplinary Research and Graduate Education student Seong Jin An works with lithium-ion batteries undergoing an ORNL-developed fast-formation protocol that shortens part of battery

A new process developed by Oak Ridge National Laboratory could alleviate a bottleneck in battery manufacturing and deliver higher capacity batteries for electric vehicles and consumer devices. The formation process – where batteries undergo repeated cycling to stabilize and activa...

A new study evaluates the atomic behavior of metals during solid state welding and finds the resulting oxide film is dissolved near the material’s surface.
Oxide removal for welding can be laborious and costly, yet results from a new study indicate the preparation may be unnecessary for certain solid-state joining. An Oak Ridge National Laboratory-led research team evaluated the atomic behavior of iron and aluminum when joined throug...
3-D visualization of chemically-ordered phases in an iron-platinum (FePt) nanoparticle.

Barely wider than a strand of human DNA, magnetic nanoparticles—such as those made from iron and platinum atoms—are promising materials for next-generation recording and storage devices like hard drives. Building these devices from nanoparticles should increase storage capaci...

The team transmitted the ORNL logo, an oak leaf, between two end points in the laboratory with 87 percent calculated fidelity. (Left): The original 4-color, 3.4kB image. (Right): The image received using superdense coding.
Researchers at the Department of Energy’s Oak Ridge National Laboratory have set a new record in the transfer of information via superdense coding, a process by which the properties of particles like photons, protons and electrons are used to store as much informatio...
A nuclear density map of the bacterial enzyme HpMTAN’s active site reveals the locations of the hydrogen atoms, including the unexpected observation of a hydrogen ion positioned midway between adenine and D198 residue.
Neutron analysis at the Department of Energy’s Oak Ridge National Laboratory is helping researchers better understand a key enzyme found in a bacterium known to cause stomach cancer. Understanding the details of this enzyme, and thus the Helicobacter pylori bacteria’s metabolis...

Snow falls in winter and melts in spring, but what drives the phase change in between?

Contrasting solvation strategies in conventional electrolytes (top-left) and a new class of Lewis-acidic polymer electrolytes (bottom-left).
Ever since Italian physicist Alessandro Volta invented the first battery out of a stack of copper and zinc disks separated by moistened cardboard, scientists have been searching for better battery materials.
