Syntheses of Novel Diamond Nanomaterials

  Despite of the recent notable development, diamond particles as small as or smaller than 10 nm are hardly available except detonation nanodiamonds. In order to attempt a breakthrough, We are investigating to produce novel types of nanodiamonds having deversified characteristics in shape and/or electronic structure. Meanwhile, homogeneous dispersion of nanodiamonds in foregn solid materials is also under development. more..

Assembly of Nanoparticles

Utilizing the excellent dispersive ability of nanodiamonds in solvents, we study self-assembling techniques to fabricate 1-3 dimensional structures, including arrays and chains on substrates, porous carbons, etc..　 more..

Bio-Inspired Materials

Biomaterials often show well-designed and/or complicated shapes hardly understandable crassical crystallograpy. We will soon start to study how creatures fabricate those architectures. 　more..

Surface Functionalization

We found that deagglomerating/crushing effect induced by high power sonication is considerably promoted in the presence of hard beads.　This novel technique provides reactants to reach reactive surfaces of agglomerating primary nanoparticles during funtionalisaton processes. An effective method to functionalise nanoparticles was successully developed.　more..
