In pure water, these tiny molecular ‘brushes’ stand straight up and maintain a slippery surface. But adding ions with +2 and +3 charges causes them to clump and lose their slipperiness (above). (Image by Institute for Molecular Engineering at the University of Chicago.)
Tiny brushes may not be as slippery as thought, study finds

A type of molecular surface thought to be extremely slippery may not stay that way under all conditions, according to a new paper in Science by Argonne researchers and the Institute for Molecular Engineering at the University of Chicago. The study may have implications for those trying to tap these surfaces for new technologies, such as joint replacements or anti-fogging surfaces.

This shows the study’s crossbar array design — vertical and horizontal electrodes with red memory cells where they intersect. “Flying out” of a single memory cell is a model of its molecular structure with tin (gold sphere) diffusing through the insulating HfO<sub>2</sub> layer (blue and white matrix). Each component is essential in forming the filament across the metal-insulator-metal stack in this resistive switching architecture. (Image by Argonne National Laboratory.)
Tin type

Argonne researchers find that tin is a silicon-friendly alternative for production of solid-state memory components.

Argonne chemists have uncovered an important and unexpected reaction mechanism –called “redox behavior”–on the surface of catalyst support materials. These materials are promising catalytic materials in their own right. (Image by Argonne National Laboratory.)
A catalytic support material takes a leading role

Chemists at Argonne and Ames national laboratories have spotted an important and unexpected reaction mechanism — called redox behavior — in some catalyst support materials that are commonly used in the chemical industry.

Oleo Sponge can be wrung out, the oil collected, and the material reused — it has stood up to dozens of cycles so far without exhibiting any degradation in performance. (Image by Argonne National Laboratory; click to view larger.)
Argonne seeks partners to commercialize Oleo Sponge technology

The U.S. Department of Energy’s (DOE’s) Argonne National Laboratory seeks partners to commercialize the Oleo Sponge, its award-winning, patent pending oil-sorbent technology.

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

Argonne scientists have determined that electrons in some oxides can experience an “unconventional slowing down” of their response to a light pulse. This behavior may result in potentially useful properties related to magnetism, conductivity or even superconductivity.

Argonne physicist Peter Mueller and his colleagues are selectively capturing and counting rare isotopes of krypton to determine the age of ice and groundwater. (Image by Argonne National Laboratory.)
Radiokrypton dating plumbs mysteries of water aquifers

Argonne physicists are using a unique, laser-based, atom-counting technique called Atom Trap Trace Analysis to selectively capture and count the krypton isotopes 81Kr and 85Kr to determine the age of ice and groundwater. The results provide valuable information about the dynamics, flow rates and direction of water in aquifers, particularly those vital to arid regions.

Better model of water under extreme conditions could aid understanding of Earth's mantle

When exposed to unimaginably high temperatures and pressures, water exhibits all sorts of weird phases and properties. Researchers from Argonne and the University of Chicago have developed simulations to predict water’s properties in these harsh conditions.
