These images show how the surface morphology and internal microstructure of an individual tin particle changes from the fresh state through the initial lithiation and delithiation cycle (charge/discharge). Most notable are the expansion in overall particle volume during lithiation, and reduction in volume and pulverization during delithiation. The cross-sectional images reveal that delithiation is incomplete, with the core of the particle retaining lithium surround by a layer of pure tin.

The galaxy NGC 4395 is shown here in infrared light, captured by NASA's Spitzer Space Telescope.

Led by IDTechEx, partners included consumer goods company Procter & Gamble, printed logic company PragmatIC, printed battery supplier Blue Spark Technologies, conductive ink and photonic curing equipment supplier NovaCentrix and Cal Poly, who designed and printed on the paper substrate.

When you look up at the Milky Way on a clear, dark night, you'll see a band of bright stars arching overhead. This is the plane of our flat spiral galaxy, within which our solar system lies.

Schematic of the spintronic thermoelectric device fabricated by the University of Utah’s researchers. This device can convert even minute heat emitted by hand-held electronic devices such as laptops, etc. into useful electricity.

This animation shows the prototype starshade, a giant structure designed to block the glare of stars so that future space telescopes can take pictures of planets.

Old-growth Amazon tree canopy in Tapajós National Forest, Brazil. A new NASA study shows that the living trees in the undisturbed Amazon forest draw more carbon dioxide from the air than the forest's dead trees emit.

A new interactive mosaic from NASA's Lunar Reconnaissance Orbiter covers the north pole of the moon from 60 to 90 degrees north latitude at a resolution of 6-1/2 feet (2 meters) per pixel. Close-ups of Thales crater (right side) zoom in to reveal increasing levels of detail.
