Advancing Nanoscience Through Largescale MD Simulations

Over the past decade, teams of engineers, chemists and biologists have analyzed the physical and chemical properties of cicada wings, hoping to unlock the secret of their ability to kill microbes on contact. If this function of nature can be replicated by science, it may lead to products with inherently…

ORNL Scientists Tap into AI to Put a New Spin on Neutron Experiments

Scientists seek to use quantum materials—those that have correlated order at the subatomic level—for electronic devices, quantum computers, and superconductors. Quantum materials owe many of their properties to the physics that is occurring on the smallest scales, physics that is fully quantum mechanical. Some materials, such as complex magnetic materials,…

Titan Supercomputer and Spallation Neutron Source Unite to Probe the Inner Workings of c-Src kinase

Proteins are the workhorses of our body’s cells, performing vital functions we can’t live without—everything from helping form antibodies to transporting nutrients to providing structure for the cells themselves. The individual role of each protein can be determined by studying its unique three-dimensional structure. However, one particular class of protein…

Broadening the Bilayer

To better understand the biological processes that govern lipid raft formation—processes with broad implications for research ranging from how cells regulate proteins to how viruses invade healthy human cells—ORNL researchers are using two world-class research facilities to study the presence and formation of these nanoscale lipid patches.

Titan Helps Unpuzzle Decades-Old Plutonium Perplexities

A team of condensed matter theorists at Rutgers University used nearly 10 million Titan core hours to calculate the electronic and magnetic structure of plutonium using a combination of density functional theory calculations and the leading-edge dynamical mean field theory technique.
