Lawrence Fung, Stanford University, gives his presentation, "Maximizing the Potential of Neurodiversity in the Employment and Educational Settings," at the All-Summit Closing Plenary.
While conducting experimental work to develop new semiconductors, PNNL scientists discovered a novel new compound—Cd3Ge2As4. The new material potentially has applications in infrared optics and electronics. This image is of a SEM backscatted electron detector micrograph and accompanying energy dispersive spectroscopic elemental dot map. The different colors are due to birefringence in the crystal caused by light traveling at different speeds along different crystallographic axes and show the spatial distribution of Cd (red), Ge (blue), and As (green). The image was captured by scientist Brad Johnson. The team of researchers on this project includes Brian Riley, Joe Ryan, John McCloy, Jarrod Crum, and SK Sundaram.
This image was a part of the 2010 PNNL Science as Art contest.

Scientists at Argonne found they could create these tiny "snakes" out of particles of nickel (white) by tinkering with the magnetic fields and water flow. The snakes assemble themselves and even "swim" in response to water currents.
--more details--
Self-assembled magnetic snake in far-from-equilibrium magnetic ensembles at the water-air interface. These structures are spontaneously created from magnetic microparticles as a result of intricate interplay between magnetic forces and water flows. Snakes are accompanied by water currents which often force them to swim. White objects in the picture correspond to nickel particles. One sees individual particles as well as linear chains formed by particles. Arrows and background colors designate the velocity field and magnitudes of the surface flows.

This research encompasses the growth of nanoscale GaAs membranes with integrated quantum heterostructures. The particular orientation provides parallel defect-free growth. Their elongated shape and nanoscale lateral size combined with the heterostructures will provide the path for tailored defect-free

A team of scientists at Argonne National Laboratory, Northwestern University and Stony Brook University has, for the first time, created a two-dimensional sheet of boron – a material known as borophene.
Scientists have been interested in two-dimensional materials for their unique characteristics, particularly involving their electronic properties. Borophene is an unusual material because it shows many metallic properties at the nanoscale even though three-dimensional, or bulk, boron is nonmetallic and semiconducting.

Kevin Golovin, a graduate student in materials science and engineering at U-M, demonstrates a new rubbery material that can create ice repelling, or "icephobic," coatings on a variety of materials, such as windshields or ship hulls. In this photo, the "icephobic" coating was applied to the right half of a license plate, preventing ice from sticking to that half after being placed in a freezer. The research is being done under the direction of Anish Tuteja, an associate professor in U-M's Department of Materials Science & Engineering.

Like a Venus flytrap, a newly discovered chemical material is a picky eater—it won't snap its jaws shut for just anything. Instead of flies, however, its favorite food is radioactive nuclear waste.
Mercouri Kanatzidis, a scientist at the U.S. Department of Energy's (DOE) Argonne National Laboratory, and Nan Ding, a chemist at Northwestern University, have crafted a sulfide framework that can trap radioactive cesium ions. This mechanism has the potential to help speed clean-up at power plants and contaminated sites.
Above left: the metal sulfide framework's default conformation leaves a pore open to attract positive ions from the surroundings.
Above right: with a Cesium ion inside, the framework changes to trap the ion.

Pacific Northwest National Laboratory developed process makes it more feasible for the auto industry to incorporate magnesium alloys into structural components. The method has the potential to reduce costs by eliminating the need for rare-earth elements, while simultaneously improving the material's structural properties.
The PNNL team designed and commissioned an industrial version of their idea: A one-of-a-kind, custom built Shear Assisted Processing and Extrusion machine — coining the acronym for ShAPE™.

Magnesium — the lightest of all structural metals — has a lot going for it in the quest to make ever lighter cars and trucks that go farther on a tank of fuel or battery charge.
A new process developed at Pacific Northwest National Laboratory should make it more feasible for the auto industry to incorporate magnesium alloys into structural components. The method has the potential to reduce cost by eliminating the need for rare-earth elements, while simultaneously improving the material's structural properties. It's a new twist on extrusion, in which the metal is forced through a tool to create a certain shape, kind of like dough pushed through a pasta maker results in different shapes.
