Bimetallic Nanomaterials are in the focus of the newest Special Issue in Particle & Particle Systems Characterization. This Issue, published in May 2018 and entitled “Beyond the Gold Standard: Bimetallic Nanomaterials Bring New Properties and Functions”, is guest edited by  Sara E. Skrabalak, Jingyi Chen, Svetlana Neretina, and Dong Qin. Six Communications and ten Full Papers highlight how advances in synthesis enable new bimetallic materials with novel and enhanced properties for diverse applications. Different types of bimetallic nanoparticles including random alloys, intermetallics, heterostructures, and core@shell architectures cover the full range of recent developments as described in the Editorial.
