Back Cover: Direct Observation of Growth and Self‐assembly of Pt Nanoclusters in Water with the Aid of a Triblock Polymer Using in situ Liquid Cell Transmission Electron Microscopy (TEM) (Chin. J. Chem. 8/2017)

The back cover picture shows schematic of direct in situ liquid cell TEM observation of electron bean induced growth and self‐assembly of nanoclusters in water with the aid of a triblock copolymer. The growth and self‐assembly of the Pt nanoclusters with the aid of triblock copolymer F127 are directly observed, and a surfactant guided nanocluster formation mechanism is proposed. Dramatic differences are found on the cluster forming behavior and final morphologies between thick and thin liquid regions. The difference in precursor availability and charging effects are attributed to the different growth behavior in different thickness regions. More details are discussed in the article by Chen et al. on page 1278–1283.
