Magnetic order in (Sr,Na)Fe<sub>2</sub>As<sub>2</sub>: The crystal structure contains planes of iron atoms (shown as red spheres). Half the iron sites have a magnetization (shown as red arrows), which points either up or down, but the other half have zero magnetization. This shows that the magnetism results from the constructive and destructive interference of two magnetization waves, a clear sign that the magnetic electrons are itinerant, which means they are not confined to a single site. The same electrons are responsible for the superconductivity at lower temperature.
New magnetism research brings high-temp superconductivity applications closer

An Argonne research team has discovered that only half the atoms in some iron-based superconductors are magnetic, providing the first conclusive demonstration of the wave-like properties of metallic magnetism.

Reference electrodes provide insights into a battery cell's health. The image above depicts two reference electrodes within a battery cell. This configuration that allows researchers to evaluate a battery's anode and cathode separately at all stages of cycling and aging.
Argonne continues to pave way to improved battery performance testing

Scientists have demonstrated that the placement and type of a tiny measurement device called a reference electrode enhances the quantity and quality of information that can be extracted from lithium-ion battery cells during cycling.

A rotating particle creates a flow that pushes swimming bacteria into a spiral-shaped halo around the center. The discovery helps scientists understand the interaction of microswimmers and could help prevent films from forming in microfluidic devices such as labs-on-a-chip.

Moving microswimmers with tiny swirling flows

Argonne scientists have discovered a way to use a microscopic swirling flow to rapidly clear a circle of tiny bacteria or swimming robots.

One of the small businesses with whom Argonne will collaborate is Transient Plasma Systems (TPS) of Torrance, Calif. TPS has developed a new type of ignition system that allows engines to run leaner or tolerate higher levels of recirculated exhaust gas, thereby increasing efficiency. Pictured is Argonne researcher Michael Pamminger working on a test engine that will be used as part of the TPS-Argonne collaboration.
Three clean tech small businesses matched with Argonne in DOE program

Three clean tech small businesses have received vouchers from the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy to be redeemed at Argonne as part of DOE’s Small Business Vouchers Pilot program.

Argonne scientist Carmen Soriano and Yale researcher Victoria McCoy position Tully Monster fossils for close examination at a beamline in the Advanced Photon Source.
Solving the mystery of the Tully Monster

With the use of the Advance Photon Source, a Yale-led team of paleontologists has determined that the 300-million-year-old animal — which grew to only a foot long — was a vertebrate, with gills and a stiffened rod (or notochord) that supported its body.

Argonne and Marathon join forces to optimize fuels and engines

Argonne is partnering with Marathon Petroleum Corporation to look at engines and fuels holistically, optimizing both areas simultaneously in search of greater efficiency. By advancing on both fronts, the researchers hope to make substantial gains that would not be possible by working on engines and fuels individually.

The Electrocatalysis Consortium (ElectroCat) is using national lab resources and capabilities such as Argonne National Lab's High-Throughput Research facility (pictured) and Los Alamos National Lab's multiscale modeling techniques to develop catalysts and test their performance in fuel cells, speeding the process of discovery.
Argonne and Los Alamos national laboratories team up to develop more affordable fuel cell components

Researchers at Argonne and Los Alamos national laboratories have teamed up to support a DOE initiative through the creation of the Electrocatalysis Consortium (ElectroCat), a collaboration devoted to finding an effective but cheaper alternative to platinum in hydrogen fuel cells.

The antibiotic globomycin shuts down lipoprotein maturation by blocking the active site of the processing enzyme lipoprotein signal peptidase (LspA). Researchers hope their blueprint of LspA-globomycin will inform drug design so that analogues may be developed to fight a plethora of common but devastating infections.
Scientists blueprint antimicrobial candidate with promise in stemming the onrushing post-antibiotic tide

Researchers hope their blueprint of LspA-globomycin will inform drug design so that analogues may be developed to fight a plethora of common but devastating infections.

Argonne is working with Achates Power and Delphi Automotive to develop an advanced engine that could yield efficiency gains of up to 50 percent. This illustration shows how such an engine operates, with opposed pistons moving toward each other, compressing gasoline until it auto-ignites. Illustration courtesy of Achates Power
Argonne, Achates Power and Delphi Automotive to investigate new approach to engines

Argonne National Laboratory is working with Achates Power, Inc., and Delphi Automotive to develop an innovative new engine that could yield efficiency gains of up to 50 percent over a comparable conventional engine.

Here are “stills” from an X-ray “movie" of an exploding nanoparticle. The nanoparticle is superheated with an intense optical pulse and subsequently explodes (left). A series of ultrafast X-ray diffraction images (right) maps the process and contains information how the explosion starts with surface softening and proceeds from the outside in.
Scientists take nanoparticle snapshots

An international team of researchers led by Christoph Bostedt of Argonne and Tais Gorkhover of SLAC National Accelerator Laboratory used two special lasers to observe the dynamics of a small sample of xenon as it was heated to a plasma.
