Chikwata chetsvakiridzo chinoumbwa nemudzidzi wePh.D Kento Katairi uye Associate Purofesa Masayoshi Ozaki weGraduate School of Engineering, Osaka University, Japan, naProfessor Toruo Iriya vanobva kuResearch Center yeDeep Earth Dynamics yeEhime University, nevamwe, vakajekesa simba re nano-polycrystalline diamond panguva yekumhanya-mhanya deformation.

Chikwata chekutsvagisa chakasvibisa makristallites ane saizi yakakura yemakumi ema nanometers kuita dhaimondi mu "nanopolycrystalline" mamiriro, uye ndokuisa ultra-high pressure kwairi kuti iongorore simba rayo.Kuedza uku kwakaitwa pachishandiswa laser XII laser ine hombe pulse kubuda simba muJapan.Observation yakawana kuti kana dzvinyiriro huru yemamiriyoni gumi nematanhatu emuchadenga (kanopfuura ka4 kumanikidza kwepakati penyika) ikaiswa, vhoriyamu yedhaimondi inoderedzwa kusvika isingasviki hafu yehukuru hwayo hwepakutanga.

Iyo data yekuyedza yakawanikwa panguva ino inoratidza kuti simba re nano-polycrystalline diamond (NPD) rinopfuura zvakapetwa kaviri iro reyakajairika single crystal diamond.Zvakaonekwa zvakare kuti NPD ine simba repamusoro pakati pezvinhu zvese zvakaongororwa kusvika zvino.
