Our research aims to create innovative functional inorganic materials through curiosity-driven exploratory synthesis and rational elucidation of the synthesis-structure-property relationship. Through cutting-edge research, we provide a unique learning opportunity for students and young researchers, equipping them with professional skills and fostering international communication.<\/p>\n\n\n\n

1) Curiosity-driven exploration of non-oxide materials with exciting properties<\/h2>\n\n\n\n

The discovery of novel structures driven by curiosity-based exploration is essential for the advancement of chemistry. By combining a variety of elements from the periodic table, we can create new structures with exciting properties. We mainly focus on non-oxide compounds with different anions, such as N3\u2212<\/sup>, NCN2\u2212<\/sup>, and Cl\u2212<\/sup><\/sup>. Nitride anion (N3\u2212<\/sup>) is a trivalent one with a similar ionic radius with divalent oxide anion (O2\u2212<\/sup>), and various properties arise with different local and average structures, emerging ferroelectric or electrocatalytic applications. The valence of NCN2\u2212<\/sup> is the same as that of O2\u2212<\/sup>, but this molecular anion with a bar shapes show unique thermal- or pressure-dependent luminescence properties. Cl\u2212<\/sup> is a larger and softer ion, which brings unique mechanical properties and excellent ion transport that is important for energy applications, such as all-solid-state batteries. We also focus on novel synthesis method for producing new compounds and structural analysis of synthesized materials, which clarifies the structure-property relationship.<\/p>\n\n\n\n

    2) Elucidation of the synthesis-structure-property relationship toward efficient synthesis<\/h2>\n\n\n\n

    The exploration of inorganic compounds synthesized to date has required considerable effort and time. In the search for next-generation materials, more efficient methods are in demand. Computational science can estimate the thermodynamic driving force from reactants to products, but predicting the synthesis pathways of target substances remains challenging since products are formed through processes involving long-range diffusion and nucleation to form specific crystals. Therefore, to design material synthesis efficiently and rationally, it is crucial to understand synthesis methods through both thermodynamics and kinetics. In-situ synchrotron XRD and in-situ electron microscopy observations are powerful tools for understanding synthesis methods, as they allow us to observe reaction processes during heating. By combining synthesis experiments, computational science, and in-situ analysis, we aim to develop innovative new materials efficiently through a rational understanding of synthesis reactions.<\/p>\n\n\n\n

      We have collaborated with various domestic and international universities and companies. We have strong collaborations for synchrotron and neutron analysis of detailed average and local structures and understanding reaction mechanism. We intensively collaborate with computational teams to understand synthesis and property insights from structure and energy analysis.<\/p>\n\n\n\n
