Five myths about diesel engines

Argonne mechanical engineer Steve Ciatti takes a crack at some of the more persistent myths surrounding diesel technology.

Fenter has spent much of his career at Argonne studying “interface dynamics”—the particular physical and chemical processes that occur at the boundaries between different materials.
Argonne physicist Fenter wins Warren Award for X-ray diffraction studies

Paul Fenter, a physicist at Argonne National Laboratory, has been named the next recipient of the American Crystallographic Association's Bertram E. Warren Award, which recognizes contributions to the physics of solids through the use of diffraction-based techniques.

U.S. Department of Energy Secretary Steven Chu, joined Senator Richard Durbin, University of Chicago President Robert Zimmer and Argonne Director Eric Isaacs to break ground for Argonne's new Energy Sciences building.
Chu, Durbin break ground for new Energy Sciences Building

U.S. Energy Secretary Steven Chu and U.S. Sen. Dick Durbin joined officials from Argonne National Laboratory and the University of Chicago at a groundbreaking event Friday, June 3, for a new Energy Sciences Building at Argonne.

Inorganic surface ligands enable facile electron transport between quantum dots and opened novel opportunities for using nanostructures in solar cells.
New inorganic semiconductor layers hold promise for solar energy

A team of researchers from the University of Chicago and Argonne National Laboratory has demonstrated a method that could produce cheaper semiconductor layers for solar cells.

This molecular schematic of “nanobowls” illustrates an example of a new catalytic paradigm that may help in the development of new biofuels.
Putting the 'fuel' in biofuels

Recent discussions of methods by which biomass—grasses, trees, and other vegetation—could be turned into fuel makes a lot of sense in theory. Plant matter is composed of energy-intensive carbohydrates, but even now scientists still don't have the perfect solution for converting plant sugars into combustible fuels.

Chemist Lisa Utschig tests a container of photosynthetic proteins linked with platinum nanoparticles, which can produce hydrogen from sunlight. Tiny bubbles of hydrogen are visible in the container at right.
Nanoparticles help scientists harvest light with solar fuels

A group of scientists at Argonne National Laboratory, led by chemist Lisa Utschig, has linked platinum nanoparticles with algae proteins, commandeering photosynthesis to produce hydrogen instead. The system produces hydrogen at a rate five times greater than the previous record-setting method.

Two views of the atom trap used in the experiment.  On the left, the signal indicates that the trap is empty, while the picture on the right shows a “hot spot” indicating that an atom of argon-39 is contained within the trap.
Argonne researchers develop new tool for climatological dating

A new technique recently developed at Argonne National Laboratory may give researchers another tool for radioactive dating that could be of particular use in studying the history of climate change.

Steve Ciatti, Argonne engineer, works on the gas-diesel hybrid engine.
Combining gas and diesel engines could yield best of both worlds

It may be hard to believe, but the beloved gasoline engine that powers more than 200 million cars across America every day didn't get its status because it's the most efficient engine. Diesel engines can be more than twice as efficient, but they spew soot and pollutants into the air. Could researchers at Argonne National Laboratory engineer a union between the two—combining the best of both?

Argonne's energy research seeks ways to make our energy cleaner.
Argonne highlights green research in honor of Earth Day

The lab's research seeks both cleaner energy—solar cells, batteries and biofuels, among others—and ways to reduce man's environmental footprint, including reducing agricultural runoff and ways to safely clean up contaminated land.

Newer, faster supercomputers have allowed scientists to create detailed models of blood flow that help doctors understand what happens at the molecular level.
Blood vessel simulation probes secrets of brain

Zoom down to one artery in your body, and the commotion is constant: blood cells hurtle down the passage with hundreds of their kin, bumping against other cells and the walls as they go. The many variables—and the sheer immensity of the human circulatory system—have kept scientists from closely documenting the rough-and-tumble life inside blood vessels.
