TL;DR: The periodic shell structure and surface reconstruction of metallic FePt nanoparticles with icosahedral structure has been quantitatively studied by high-resolution transmission electron microscopy with focal series reconstruction with sub-angstrom resolution and finds the lattice spacing of (111) planes in the surface region to be size dependent.

TL;DR: In this article, an inert-gas condensation method with in-flight annealing was used to construct icosahedral FePt nanoparticles with hard-magnetic properties.

TL;DR: In this paper, the authors present results of x-ray absorption spectroscopy and xray magnetic circular dichroism investigations at the edges of Fe in FePt nanoparticles.

TL;DR: In this article, a size-selected SnO1.8 and Ag nanoparticles with a fixed diameter of 20 nm were used to assess the influence of these parameters on the gas-sensing properties of the films, here for ethanol vapor in synthetic air.

TL;DR: In this article, multiply twinned FePt nanoparticles with icosahedral structures were prepared by dc magnetron sputtering in argon and irradiated with 5keV He ions, which resulted in a transformation into predominantly single crystalline fcc particles at high ion fluences of f>1017ions∕cm2.
