An electrochemical cell made with a 3-D printer for studies using high-energy X-rays. This would take five to six months longer to make in aluminum, be cost-prohibitive and difficult to machine in a mix of metal and nonconductive material. The polymer-based sample holder can maintain a flow of electrodes, temperature and charge in the chamber while the holder is angle in the beam to gather different scattering patterns. Scientists working with the Advanced Photon Source at Argonne National Laboratory can conduct studies remotely by sending in these filled sample holders. The black tape represents a glassy carbon electrode. The amber film prevents X-ray scattering and serves as a window to isolate the sample environment. May 2014.

Using supercomputers and data mining, a team led by engineers at UC San Diego has discovered and developed a new phosphor to make LEDs with excellent color quality. Under UV light, the phosphor emits either green-yellow or blue light depending on the chemical activator that is mixed in.
Researchers published the new phosphor on Feb. 19 in the journal Joule.

Phones and computers have come a long way since the 1950s - so that a smartphone in your pocket is far more powerful than the 1953 30-ton behemoth called ENIAC.
The magic technology that makes this possible is the silicon transistor. But we can't keep up this pace of shrinking them forever - as they get smaller, transistors get less efficient and start to leak power as heat. Sooner or later the reign of transistors has to end.
Argonne scientists are hard at work on basic research on a number of technologies that could lead to the next transistor. Read more »

A paramount issue impacting the performance, safety, and life extension of current light-water reactors is the environment-induced cracking of metallic structural components. Understanding their structure and chemistry, as well as how they react to various aqueous environments, is important to determining their real-world behavior. Metallography is one of the tools in determining microstructure. Using a light etching technique, the crystallographic orientation of the metal can easily be observed. This scanning electron microscopy image taken in backscatter mode illustrates how crystallographic pits are formed on the metal surface when exposed to acid. Imagery provided by PNNL researcher Matthew Olszta. Other contributors are Robert Seffens, Clyde Chamberlin, Mychailo Toloczko and Stephen Bruemmer. Image colored by PNNL graphic designer Jeff London.

Argonne Distinguished Fellow Nenad Markovic and his colleagues used Argonne’s Advanced Photon Source to get a “fingerprint” of the electronic structure of the material strontium ruthenate. They noticed that the stability of the material was closely related to the tendency of its electrons to form certain kinds of bonds. This image shows the incident X-rays on the sample during the oxygen evolution reaction. Read more »

Scanning electron microscopy image of platinum nanoparticles grown by atomic layer deposition(ALD) on the faces of strontium titinate nanocubes. TheSrTiO3 single-crystal cubes are grown by hydrothermal methods to have 60-nm-long edges. Precise control over the Pt particle size, dispersion, and chemical state is achieved by controlling the number of ALD cycles. These nanostructured materials have applications in heterogenous catalysis.

A copper tetramer catalyst created by researchers at Argonne National Laboratory may help capture and convert carbon dioxide in a way that ultimately saves energy. Read more »
It consists of small clusters of four copper atoms each, supported on a thin film of aluminum oxide. These catalysts work by binding to carbon dioxide molecules, orienting them in a way that is ideal for chemical reactions. The structure of the copper tetramer is such that most of its binding sites are open, which means it can attach more strongly to carbon dioxide and can better accelerate the conversion.

Argonne researchers discovered that iridate oxides display some of the same characteristics as high-temperature superconductors, an interesting find that may lead to better understanding of superconductivity theory and possibly the discovery of additional superconductors. One of those characteristics is Fermi arcs, shown above in an iridate oxide doped with potassium ions. As the potassium added goes from 0.5 ML to 1.0 ML, the arc extends and makes a complete Fermi surface. Image courtesy B.J. Kim/John Mitchell.
