Itsinda ry’ubushakashatsi rigizwe n’umunyeshuri wa PhDD Kento Katairi na Porofeseri wungirije Masayoshi Ozaki wo mu Ishuri Rikuru ry’Ubwubatsi, Kaminuza ya Osaka, mu Buyapani, na Porofeseri Toruo Iriya wo mu kigo cy’ubushakashatsi cy’ubushakashatsi bw’ubushakashatsi bw’ubushakashatsi bwakozwe na kaminuza ya Ehime, n’abandi, basobanuye imbaraga za diyama nano-polycrystalline mu gihe cyo guhindura ibintu byihuse.

Itsinda ry’ubushakashatsi ryacumuye kristu ifite ubunini ntarengwa bwa nanometero icumi kugira ngo ikore diyama muri leta ya “nanopolycrystalline”, hanyuma iyishyiraho ingufu zidasanzwe kugira ngo ikore iperereza ku mbaraga zayo. Ubushakashatsi bwakozwe hifashishijwe laser XII laser ifite ingufu nini zisohoka mu Buyapani. Ubushakashatsi bwerekanye ko iyo hashyizweho umuvuduko ntarengwa wa miriyoni 16 z’ikirere (inshuro zirenga 4 umuvuduko w’ikigo cyo hagati), ingano ya diyama iragabanuka kugeza munsi ya kimwe cya kabiri cy’ubunini bwayo bwa mbere.

Amakuru yubushakashatsi yabonetse muriki gihe yerekana ko imbaraga za diyama nano-polycrystalline (NPD) zirenze inshuro ebyiri izo diyama isanzwe isanzwe. Byagaragaye kandi ko NPD ifite imbaraga nyinshi mubikoresho byose byakorewe iperereza kugeza ubu.
