Changes in color of coated (painted) aluminum surfaces exposed to broad-band synchrotron radiation (10–2000 eV) are investigated as a function of radiation dose (N). Quantitative color differences [Formula: see text] before and after exposure are obtained from spectral diffuse reflectance measurements using the standard CIELAB formula. The results indicate that the dose–response curve of the color-coated surfaces at large photon doses can be described as [Formula: see text] where d is a material-dependent constant.
AbstractPalladium nanowires have been electrodeposited into mesoporous silica thin film templates. Palladium continually grows and fills silica mesopores starting from a bottom conductive substrate, providing a ready and efficient route to fabricate a macroscopic palladium nanowire thin films for potentially use in fuel cells, electrodes, sensors, and other applications. X-ray diffraction (XRD) and transmission electron microscopy (TEM) indicate it is possible to create different nanowire morphology such as bundles and swirling mesostructure based on the template pore structure.
