File:Gold nanoparticles and crystal formation using AF aerogels.jpg

English: "a) Formation of gold nanoparticles on the surface of AF aerogel after adsorption of a 10 ppm gold metal mixture. b) Gold crystal formation on AF aerogel in a 4 mL glass vial containing the 1000 ppm metal mixture. c) Optical microscopy images taken from a sample of the AF aerogel shown in (b). d) SEM image of an AF aerogel loaded with newly formed gold crystals. e) XRD pattern of gold nanoplates obtained by the adsorption and reduction of Au3+ by AF aerogel. f) AFM of gold hexagonal microplates formed by AF (the inset shows the height distribution along the profile line). g) The HAADF–STEM image. h) The color map of the EDS spectrum image of the particle in (g) shows the color overlay of Au-Lα and C-Kα signals. i) The BF STEM micrograph of an Au-platelet and the corresponding SAD pattern acquired from the particle in the electron diffraction mode. The SAD pattern reveals the [111] plane orientation of the particle platelet."
