How did the collaborationo nt his project start? This work is ac ollaboration between two research groups in Waseda University (Kuroda-Shimojima-Wada Laboratory,w ith an interest in the synthesis of inorganic solids from molecular precursors) and the University of To kyo (Mizuno-Yamaguchi Laboratory, with an interest in the catalysis of metal oxide cluster compounds like polyoxometalates). The collaboration started when one of the authors (Y.K.) moved between these groups. During many discussions , we came to the idea that several polyoxometalates can be regarded as building blocks of inorganic solids, and techniques developed specially for the chemical design of polyoxometalates can also be applied to inorganic solids like brucite-type layered metal hydroxides. Thus, we succeeded in establishing the novel synthetic concept of hybrid metal hydroxide nanosheets by combining the chemistries of layered metal hydroxides and polyoxometalates. What is the most significant result of this study? The modification reaction developed in this study can be applied to aw ide range of materials, in terms of constituent metallic elements of metal hydroxide nanosheets and those of surface functional groups. Because tripodal ligands have flexible tridentate binding sites, they can adjust their conformations to metal hydrox-ide nanosheets with different lattice constants;t his is expressed by the phrase "one-size-fits-all modifier" in the title. What was the inspiration for this cover design? The cover design was inspired by the Japanese Sushi culture. We enjoy various fishes in as tandardized style, in which as lice of af ish is placed on av inegared rice ball. In this study,w ec an provide various metal hydroxide nanosheets in as tandardized method. The future goal of this study will be the production of designed nanosheets which satisfy the demands of functional devices , in the same way as aS ushi master makes flavored Sushi that fits the customer's taste. Invited for the cover of this issue is the group of Yoshiyuki Kuroda and Kazuyuki Kuroda at the Waseda University in Tokyo. The image depicts how the production of diverse metal hydroxide nanosheets can be standardized in the same way as Sushi. Read the full text of the article at
