John Carlisle, director of Chain Reaction Innovations (CRI) at Argonne, is seen here introducing the opening of the second CRI cohort pitch on February 7. Six innovators were chosen from that competition and will work to grow their technologies at Argonne over the next two years. (Image by Argonne National Laboratory.)

This shows the reaction mechanism for converting hydrogen fluoride (HF) impurity from the electrolyte into lithium fluoride (LiF) in the solid-electrolyte interphase (SEI) with release of hydrogen gas (H<sub>2</sub>). The SEI layer is shown on a substrate of gold (Au) atoms, which serves as a simplified model system. Scientists determined this mechanism using advanced computational methods (density functional theory and molecular dynamics simulations). (Image by Argonne National Laboratory.)
 Battery’s hidden layer revealed

An international team led by Argonne National Laboratory makes breakthrough in understanding the chemistry of the microscopically thin layer that forms between the liquid electrolyte and solid electrode in lithium-ion batteries. The results are being used in improving the layer and better predicting battery lifetime.

 Sending electrons on a roller-coaster ride

A first-of-its-kind X-ray instrument for frontier research with high-brightness X-rays is now in operation at Argonne National Laboratory. The new device uses a unique superconducting technology that speeds electrons on a path much like that of a roller coaster.

For the first time, Argonne scientists and other collaborators observed the mirror-like physics of the superconductor-insulator transition. They now see it operates exactly as expected. (Image by Shutterstock / ktsdesign.)
Mirror, Mirror

The mirror-like physics of the superconductor-insulator transition operates exactly as expected. Scientists know this to be true following the observation of a remarkable phenomenon, the existence of which was predicted three decades ago but that had eluded experimental detection until now. The observation confirms that two fundamental quantum states, superconductivity and superinsulation, both arise in mirror-like images of each other.

 University teams to compete in Department of Energy’s 2018 National Cyber Defense Competition

The U.S. Department of Energy is proud to announce the 29 university teams selected to compete in the third annual Cyber Defense Competition (CDC), taking place April 6–7, 2018.

 What a mesh

A team of scientists from across the U.S. has found a new way to create molecular interconnections that can give a certain class of materials exciting new properties, including improving their ability to catalyze chemical reactions or harvest energy from light.

Argonne researchers helped identify the process by which holes get trapped in nanoparticles made of zinc oxide, a material of potential interest for solar applications because it absorbs ultraviolet light. (Image by Christopher Milne.)
 It’s a trap!

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have published a new study that identifies the process by which holes get trapped in nanoparticles made of zinc oxide, a material of potential interest for solar applications because it absorbs ultraviolet light.

Using Argonne’s Advanced Photon Source, researchers identified a form of water known as Ice-VII, which was trapped within diamonds that crystallized deep in the Earth’s mantle. (Image courtesy of the University of Chicago.)
 Argonne’s powerful X-rays key to confirming water source deep below Earth’s surface

A study published in Science last week relies on extremely bright X-ray beams from the U.S. Department of Energy’s Advanced Photon Source at Argonne National Laboratory to confirm the presence of naturally occurring water at least 410 kilometers below the Earth’s surface. This exciting discovery could change our understanding of how water circulates deep in the Earth’s mantle and how heat escapes from the lower regions of our planet.
