<P>We demonstrated the Talbot effect using a broadband hard x-ray beam (?관/관 ~1). The exit wave-field of the x-ray beam passing through a grating with a sub micro-meter scale period was successfully replicated and recorded at effective Talbot distance, Z(T). The period was reduced to half at Z(T)/4 and 3/4Z(T), and the phase reversal was observed at Z(T)/2. The propagating wave-field recorded on photoresists was consistent with a simulated result.</P>

<P>We report a study of the oxidation process of individual PtNi nanoparticles (NPs) conducted with a novel scanning multi-layer Laue lens X-ray microscope. The elemental maps reveal that alloyed PtNi NPs were transformed into Pt/NiO core-shell NPs by thermal oxidation. The observations furthermore indicate that a coalescence of Pt/NiO core-shell NPs occurred during oxidation.</P>
