Laboratory/research office Laboratory for Functional Nanomaterials
Taking advantage of intermolecular interactions and chemical bonding, we are working to create novel functional nanomaterials composed of various combinations of organic materials, inorganic materials, and macromolecules. In particular, by precisely controlling chemical reactions and equilibriums in terms of physical chemistry, we can develop a new synthetic methodology for achieving beyond the range of conventional approaches. Through our innovations, we open up a new horizon and an opportunity for nanomaterial chemistry to contribute to next-generation energy production and technology.
