JAMES WEBB SPACE TELESCOPE: SCIENCE OPPORTUNITIES AND MISSION PROGRESS

The James Webb Space Telescope, the planned successor for the Hubble Space Telescope and the Spitzer Space Telescope, is making excellent technical progress. It will carry four instruments to cover the wavelength range from 0.6 to 28 µm with imaging, spectroscopy, and coronography, and will have a deployable 6.5 m aperture telescope cooled to about 40 K. It will be launched by an Ariane 5 vehicle from French Guiana to reach an orbit around the Sun-Earth Lagrange point L2. Two of the flight instruments are completed ...

José Solla-Gullon - Recent advances and remaining challenges on the use of shape-controlled-metal nanoparticles in Electrocatalysis

The incorporation of shape-controlled metal nanoparticles in Electrocatalysis is contributing significantly to a better understanding of the correlations between surface structure and electrochemical reactivity at the nanoscale [1,2]. In this communication, some of the basic requirements to properly use these shaped metal nanoparticles in electrochemical reactions including surface cleanness, and correlations between particle shape and surface structure will be reported. Then, some recent advances in the application of these shaped nanomaterials for different electrochemical reactions of interest will be highlighted [3-5]. Finally, some of the most important remaining challenges on this ...
