Out of thin air

Argonne researchers conducted basic science computational studies as part of a collaboration with researchers at the University of Illinois at Chicago to design a “beyond-lithium-ion” battery cell that operates by running on air over many charge and discharge cycles. The design offers energy storage capacity about three times that of a lithium-ion battery, with significant potential for further improvements.

Argonne and Brookhaven researchers observed two kinds of defects forming in individual nanowires, depicted here. These nanowires are smaller in diameter than a human hair. (Image by Megan Hill/Northwestern University.)
Scientists have a new way to gauge the growth of nanowires

In a new study, researchers from the U.S. Department of Energy’s Argonne and Brookhaven National Laboratories observed the formation of two kinds of defects in individual nanowires, which are smaller in diameter than a human hair.

Argonne researchers and their collaborators sought to understand what happens when an electron is injected into water. They found that the electron binds with the water; however, its binding energy is much smaller than previously thought. (Image courtesy of Peter Allen/Institute for Molecular Engineering.)
Electrons in the water

Scientists have been able to experimentally measure the electron affinity of water, determining what happens to an electron when it is injected into water. The result has importance for photochemical cells and may force scientists to a reexamine certain theories about electronic binding energy.

In a newly discovered twist, Argonne scientists and collaborators found that palladium nanoparticles can repair atomic dislocations in their crystal structure. This self-healing behavior could be worth exploring in other materials. (Image by Argonne National Laboratory.)
On the rebound

New research from the U.S. Department of Energy’s Argonne National Laboratory and Stanford University has found that palladium nanoparticles can repair atomic dislocations in their crystal structure, potentially leading to other advances in material science.

A comparison of the theoretical calculations (top row) and inelastic neutron scattering data from ARCS at the Spallation Neutron Source (bottom row) shows the excellent agreement between the two. The three figures represent different slices through the four-dimensional scattering volumes produced by the electronic excitations. (Image by Argonne National Laboratory.)
Breaking bad metals with neutrons

By combining the latest developments in neutron scattering and theory, researchers are close to predicting phenomena like superconductivity and magnetism in strongly correlated electron systems. It is likely that the next advances in superconductivity and magnetism will come from such systems, but they might also be used in completely new ways such as quantum computing.

Two Argonne scientists recognized for a decade of breakthroughs

Two scientists with the U.S. Department of Energy’s (DOE) Argonne National Laboratory have been named to the Web of Science’s Highly Cited List of 2017, ranking in the top 1 percent of their peers by citations and subject area. Materials Scientist Khalil Amine and Energy and Environmental Policy Scientist David Streets say they are thrilled to see their work — and the laboratory — recognized in such a way.

Argonne scientists and their collaborators have used a new and counterintuitive approach to balance three important factors — activity, stability and conductivity — in a new catalyst designed for splitting water. (Image by Argonne National Laboratory.)
A catalytic balancing act

Scientists have recently used a new and counterintuitive approach to create a better catalyst that supports one of the reactions involved in splitting water into hydrogen and oxygen. By first creating an alloy of two of the densest naturally occurring elements and then removing one, the scientists reshaped the remaining material’s structure so that it better balanced three important factors: activity, stability and conductivity.

Four Argonne researchers appointed fellows of scientific societies

A select group of scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory has been honored as fellows of the American Physical Society and the Electrochemical Society. Physicists Kawtar Hafidi and Michael Carpenter have been appointed as American Physical Society fellows and Materials Scientist Khalil Amine and Chemist Chris Johnson have been elected as Electrochemical Society fellows.

This shows the synthetic purple membrane assembly developed by Elena Rozhkova and fellow Argonne researchers. The assembly, which includes nanodiscs, titanium dioxide and platinum nanoparticles, can transform sunlight into hydrogen fuel. (Image by Argonne National Laboratory.)
Purple power: Synthetic ‘purple membranes’ transform sunlight to hydrogen fuel

Argonne researchers have found a new way to produce solar fuels by developing “synthetic purple membranes.” These membranes involve an assembly of lipid nanodiscs, man-made proteins, and semiconducting nanoparticles that, when taken together, can transform sunlight into hydrogen fuel.
