Itsinda ry’ubushakashatsi rigizwe n’umunyeshuri wa Ph.D 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 bwimbitse bw’isi ya kaminuza ya Ehime, n’abandi, basobanuye neza imbaraga za diyama nano-polycrystalline mugihe cyo kwihuta cyane.

Itsinda ry’ubushakashatsi ryacumuye kristu ifite ubunini ntarengwa bwa metero 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 cyubunini 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.
