Teaching the programmers of tomorrow

The CodeGirls @ Argonne camp is designed to immerse young girls in computer science before they enter high school and introduce them to potential career paths in science, technology, engineering and mathematics (STEM). Researchers from across the laboratory help the camp bring computer science to a population that’s often underrepresented in the field.

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.

Argonne researchers hope that we can rehabilitate bee and butterfly populations by allowing them to live at solar energy facilities. (Image by Argonne National Laboratory.)
Can solar energy save the bees?

In response to the population decline of pollinating insects, such as wild bees and monarch butterflies, Argonne researchers are investigating ways to use “pollinator-friendly solar power.”

This shows a) severe elemental microsegregation of the alloy as it cooled and solidified rapidly during the 3-D printing process b) how the alloy transformed during stress-relief heat treatment c) the alloy’s elemental microsegregation (right panel) leads to a much accelerated (> 1 × 102) formation of precipitate phases comparing with the nominal composition (left panel).

Putting the heat on an additive-manufactured alloy

Additive manufacturing poses unique challenges. Research at the APS has shed light on a widely used superalloy and the effects of heat. The results could help with better final products.

Maria Chan, scientist within Argonne’s Nanoscience and Technology Division, uses funds from the Laboratory Directed Research and Development (LDRD) program to study the causes of solar cell degradation. (Image by Argonne National Laboratory.)
The quest for longer-lasting solar cells

An Argonne researcher is collaborating with a user of the laboratory’s Center for Nanoscale Materials to study what makes silicon solar cells degrade. The answers may help lead to more durable solar cells and more affordable solar power.

Argonne researchers and their collaborators were able to observe the detailed dynamics of powder spattering during the 3-D printing process. Their conclusions may ultimately help a variety of industries mitigate defects. (Image by Shutterstock / MarinaGrigorivna.)
Pictures of success in 3-D printing

The better we understand additive manufacturing — or 3-D printing, the more likely it may revolutionize manufacturing. A recent Argonne paper spots possible ways to reduce powder “spattering,” which can result in defects. This new information could help businesses in many industries.

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.

Putting bacteria to work

Bacteria are diverse and complex creatures that are demonstrating the ability to communicate organism-to-organism and even interact with the moods and perceptions of their hosts (human or otherwise). Scientists call this behavior “bacterial cognition,” a systems biology concept that treats these microscopic creatures as beings that can behave like information processing systems.
