Galvanic Exchange in Colloidal Metal/Metal-Oxide Core/Shell Nanocrystals
While galvanic exchange is commonly applied to metallic nanoparticles, recently its applicability was expanded to metal-oxides. Here the galvanic exchange is studied in metal/metal-oxide core/shell nanocrystals. In particular Sn/SnO2 is treated by Ag+, Pt2+, Pt4+, and Pd2+. The conversion dynamics is monitored by in situ synchrotron X-ray diffraction. The Ag+ treatment converts the Sn cores to ...
متن کاملThe mechanism of galvanic/metal-assisted etching of silicon
Metal-assisted etching is initiated by hole injection from an oxidant catalyzed by a metal nanoparticle or film on a Si surface. It is shown that the electronic structure of the metal/Si interface, i.e., band bending, is not conducive to diffusion of the injected hole away from the metal in the case of Ag or away from the metal/Si interface in the cases of Au, Pd, and Pt. Since holes do not dif...
متن کاملA Re-Painted Amazon
This paper describes an ongoing project to digitally record, reconstruct and repaint a 2000-year-old painted Roman statue from Herculaneum, Italy. The paper considers the archaeological potential for extremely detailed laser scanning and digital recreation of Roman statuary, and visualisation within a physically accurate context. It focuses on the archaeological significance of the emerging tec...
متن کاملPainted Aperture for Portraits
Photographers often wish to control the depth of field. In particular, for portrait photography, a shallow depth of field can have dramatic effects on the composition and the feel of the picture. For example, a shallow depth of field can help direct attention to the subject by blurring out objects too close or too far from the camera, such as distracting objects or faces. Also, focusing on an o...
متن کاملElectrodeposition of metal nanostructures by galvanic displacement powered with insoluble crystals of a ferrocene derivative.
The deposition of metal nanostructures (wires and particles) on a graphite surface from an aqueous electrolyte solution was induced by galvanic displacement, via the oxidation of insoluble crystals of a ferrocene derivative (either n-butyl ferrocene or decamethyl ferrocene) present on the same substrate. Micron-to-millimetre-scale crystallites of decamethyl ferrocene were deposited on the graph...
