Cardillo-Zallo et al. report on a nanoscale system consisting of endohedral fullerenes encapsulated within single-walled carbon nanotubes, capable of the delivery and release of krypton atoms on-demand, via coalescence of host fullerene cages under the action of the electron beam (in situ) or heat (ex situ).

1.2-Billion-Year-Old Groundwater System Found in South African Mine

Jul 6, 2022 by News Staff

This image from Curiosity’s Mast Camera shows inclined strata at Zabriskie Plateau, about a third of a mile (0.5 km) northeast of the ‘Pahrump Hills’ outcrop at the base of Mount Sharp, the central peak within the Gale Crater on Mars. These sedimentary rocks are inclined toward the south and are also interpreted as the deposits of small deltas building out into a lake. The Mast Camera’s left-eye camera recorded the component frames of this mosaic on July 22, 2014, during the 696th Martian day of Curiosity’s work on Mars. The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth. Image credit: NASA / JPL-Caltech / MSSS.
