“Emergence of AI is a very rare type of event,” said Sergei Kalinin, director of ORNL’s Institute for Functional Imaging of Materials. “Once in a generation there is a paradigm shift in science, and this is ours.”

As a young girl Kelly Chipps believed she would become a field biologist. Then, in her junior year of high school, she studied physics with a teacher so in love with the subject that Chipps fell in love with it, too.

Chemists at the Department of Energy’s Oak Ridge National Laboratory have demonstrated a practical, energy-efficient method of capturing carbon dioxide (CO2) directly from air. They report their findings in Nature Energy.

Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. These incidents occasionally have grave consequences, including burns, house fires and at least one plane crash.

An Oak Ridge National Laboratory-led team used a scanning transmission electron microscope to selectively position single atoms below a crystal’s surface for the first time.

Scientists at the Department of Energy’s Oak Ridge National Laboratory induced a two-dimensional material to cannibalize itself for atomic “building blocks” from which stable structures formed.
