The MNSR reactor core is about the size of a large coffee can, contains about a kilogram of fuel and rests at the bottom of a tall column of water. The Chinese team extracted the old core, placed it in a shipping container designed by Argonne and sent it to Chinese facilities for disposition. The new core was inserted and startup operations commenced last month.
Argonne, NNSA collaborate with China to convert micro-reactor

Chinese officials announced at the recent Nuclear Security Summit that the country commenced operations on a small research reactor that was converted to use low-enriched uranium fuel in partnership with the National Nuclear Security Administration and the U.S. Department of Energy’s Argonne National Laboratory.

Reggie James, a driver for Alpha Bakery in Chicagoland, fills the tank with propane fuel. An Argonne study of Alpha’s propane fleet found the fuel switch reduced greenhouse gas emissions and saved money.
Bakery switches to propane vans

A switch to propane from diesel by a major Midwest bakery fleet showed promising results, including a significant displacement of petroleum, a drop in greenhouse gases and a fuel cost savings of 7 cents per mile, according to a study recently completed by Argonne.

Biochemists solve the structure of cell's DNA gatekeeper

Caltech scientists have produced the most detailed map yet of the massive protein machine that controls access to the DNA-containing heart of the cell, in part by using resources at the Advanced Photon Source at Argonne

Argonne researchers, from left, Assistant Computational Scientist Marta García, Principal Mechanical Engineer Sibendu Som, Mechanical Engineer Janardhan Kodavasal and Senior Software Developer Kevin Harms discuss the results of an important new project that will allow engine designers to perform as many as 10,000 engine simulations simultaneously on the supercomputer, Mira.
Engine design takes a major leap at Argonne

A team with Argonne's Virtual Engine Research Institute and Fuels Initiative (VERIFI) announce that they have completed development of engineering simulation code and workflows that will allow as many as 10,000 engine simulations to be conducted simultaneously on the Mira supercomputer.

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.
