Electrons in some oxides can experience an “unconventional slowing down” of their response to a light pulse, according to Argonne material scientists and their collaborators. This surprising behavior may result in useful properties related to magnetism, conductivity or even superconductivity. (Image by Argonne National Laboratory.)

Electrons slowing down at critical moments

In a crystal, All atoms shape an intermittent structure called a lattice, where the molecules are arranged in a tedious example in three dimensions....
This image depicts the selective functionalization of methane molecules, a chemical process that makes them more technologically desirable. The methane molecules are shown as one gray carbon atom connected to four white hydrogen atoms. The orange crystals at bottom represent the metal-organic frameworks in which the reaction takes place.

Uncovering a missing link from methane to methanol

Microscopic crystalline structures called metal-organic systems (MOFs) may give an approach to take care of one of the most serious issues in methane functionalization...
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 (H2). 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.)

Nickel in the X-ray limelight

Making chemicals for mechanical procedures regularly expects researchers to utilize an impetus — a substance that velocities up to a compound response, decreasing the...
In a new study, Argonne and University of Lille chemists explored protactinium’s multiple resemblances to more completely understand the relationship between the transition metals and the complex chemistry of the early actinide elements.

Protactinium: The element of surprise

Chemical elements on the occasional table likewise have family likenesses that could give prescient understanding into the way elements connect, driving researchers to not-yet-envisioned...
industry, pollution, smog

Scientists drew a clear picture of how nitrogen oxides are formed

Nitrogen oxides (NOx) in our atmosphere leads to the formation of smog, acid rain, and ground-level ozone. Scientists are consistently working to understand how these...
