TL;DR: The Stardust spacecraft collected thousands of particles from comet 81P/Wild 2 and returned them to Earth for laboratory study, and preliminary examination shows that the nonvolatile portion of the comet is an unequilibrated assortment of materials that have both presolar and solar system origin.

TL;DR: In this article, a photon-enhanced thermionic emission (PHE) was proposed for photovoltaic cells, which combines electric as well as thermal conversion mechanisms, leading to enhanced conversion efficiencies that potentially could even exceed the theoretical limits of conventional PV cells.
Journal ArticleDOI
Three-dimensional imaging of chemical phase transformations at the nanoscale with full-field transmission X-ray microscopy
TL;DR: A new X-ray imaging set-up is proposed, combining full-field transmission X-rays microscopy (TXM) withX-ray absorption near-edge structure (XANES) spectroscopy to follow two-dimensional and three-dimensional morphological and chemical changes in large volumes at high resolution (tens of nanometers).

TL;DR: The elements Cu, Zn, and Ga appear enriched in this Wild 2 material, which suggests that the CI meteorites may not represent the solar system composition for these moderately volatile minor elements.

TXM-Wizard: a program for advanced data collection and evaluation in full-field transmission X-ray microscopy
TL;DR: A suite of GUI programs written in MATLAB for advanced data collection and analysis of full-field transmission X-ray microscopy data including mosaic imaging, tomography and XANES imaging is presented.
