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.

The BL5-4 station is a normal incidence monochromator beam line optimized for high-resolution angle-resolved photoemission spectroscopy (ARPES) in the photon energy range of 7 - 40 eV. The dedicated experimental end station is equipped with a SCIENTA R4000 electron spectrometer. This system is capable of performing ARPES experiments with a total energy resolution of a few meV and an angular resolution of 0.3°. It is also equipped with a low-temperature sample manipulator with two degree of freedom of rotation, which can be cooled down to 5 K.

Hollow nano-cylinders were fabricated using EBL with the negative high resolution resist HSQ. Gold was evaporated on top of the coaxes, where too aggressive evaporation resulted in beautiful metal spheres on top of the sample. After polishing and exposing the HSQ using the FIB under grazing angles, these coaxes could act as negative index metamaterial at visible wavelengths, or as plasmonic nano-apertures to enhance optical trapping forces by several orders of magnitude.

Panelists discuss and answer questions from attendees at the Career Development Tools and Strategies session.
An abalone shell is made of thousands of layers of “tiles” made of calcium carbonate (more commonly known as chalk). A key to the strength of the abalone shell is a protein adhesive that binds to the top and bottom surfaces of the calcium carbonate tiles. The glue is strong enough to hold layers of tiles firmly together, but weak enough to permit the layers to slip apart, absorbing the energy of a heavy blow in the process. The images on the right show the shell's structure under increased magnification.
