Evidence is mounting, however, that useful properties of NPs can be improved further and even new NP functionality achieved by not only controlling the NP size and shape but also interfacing chemically or structurally distinct entities into single, so-called “composite” NPs. A typical example is core−shell NPs wherein the synergy of distinct atoms at the core\\shell interface endows the NPs with otherwise unachievable functionality. However, though advantageous, the concept of functional interfaces inside NPs is still pursued largely by trial-and-error. That is because it is difficut to assess the interfaces precisely at the atomic level using traditional experimental techniques and, hence, difficult to take control of. Using the core\\shell interface in less than 10 nm in size Ru core − Pt shells NPs as an example, we demonstrate that precise knowledge of the 3D atomic arrangement at functional interfaces inside NPs can be obtained by resonant high-energy X-ray diffraction (XRD) coupled to element-specific atomic pair distribution function (PDF) analysis. On the basis of the unique structure knowledge obtained, we scrutinize the still-debatable influence of core\\shell interface on the catalytic functionality of Ru core−Pt shell NPs, thus evidencing the usefulness of this nontraditional technique for practical applications.  \nKEYWORDS: composite metallic nanoparticles for catalytic applications, 3D atomic structure, resonant high-energy X-ray diffraction, element specific atomic pair distribution functions, reverse Monte Carlo simulations  \n1. INTRODUCTION  \nConfining materials to nanometer-size dimensions can lead to significant changes in their functional properties. For example, perfectly formed silicon nanospheres not only become harder than bulk silicon but are among the hardest materials known, falling between bulk sapphire and diamond.1 Another example is Au. While bulk gold is very inert, chemically, a nanoparticles (NPs) of Au catalyze various chemical reactions, including oxidation of toxic CO.2 Evidence is mounting that, in addition to controlling the NP size and shape, useful properties of NPscan be improved further, the NP stability can be enhanced, and even new NP functionality can be achieved by interfacing chemically or structurally distinct entities into single structures, often referred to as composite NPs.3−6 A typical example is the so-called core−shell NPs, wherein the synergy of distinct atoms at the core\\shell interface endows the NPs with otherwise unachievable functionality. For example, nonblinking quantum dots, such as 3 nm CdSe core−thick CdS\\SiO2\\Au shell NPs;7 efficient metal\\semiconductor structures for harvesting solar energy such, as 4 nm Ag core−2 nm TiO2 shell NPs;8 devices for controlled drug delivery and release, such as 2 nm FePt core−8 nm CoS2 shell NPs;9 multimodal contrast agents for simultaneous magnetic resonance imaging and X-ray computed tomography, such as \u003C8 nm Fe3O4 core−TaOx shell particles; 10  \nefficient catalysts for production of hydrogen peroxide (3 M tons/year), such as 10 nm Pd core−Pd2Hg5 shell particles; 11 building blocks for composites with boosted magneto-static energy, such as 4 nm Fe58Pt42 c","cbCaibvzOXbVIYys","https://ap.wps.com/l/cbCaibvzOXbVIYys","pdf",3080491,13,"English","# Abstract\n# 1.
