Iqela lophando eliqulunqwe ngumfundi we-Ph.D uKento Katairi kunye noNjingalwazi odibeneyo uMasayoshi Ozaki weSikole soBunjineli, iYunivesithi yase-Osaka, eJapan, kunye noNjingalwazi uToruo Iriya ovela kwiZiko loPhando lwe-Deep Earth Dynamics yeYunivesithi yase-Ehime, kunye nabanye, baye bacacisa amandla e-nano-polycrystalline diamond ngexesha lokuguqulwa kwesantya esiphezulu.

Iqela lophando le-sintered crystallites kunye nobukhulu obukhulu bamashumi e-nanometers ukwenza idayimane kwindawo "ye-nanopolycrystalline", kwaye emva koko ifake uxinzelelo oluphezulu kuyo ukuphanda amandla ayo. Uvavanyo lwenziwa kusetyenziswa i-laser XII laser enamandla amakhulu aphuma eJapan. Uphononongo lufumanise ukuba xa kusetyenziswa uxinezeleko oluphezulu lwe-atmospheres yezigidi ezili-16 (ngaphezu kwe-4 yoxinzelelo lombindi womhlaba), umthamo wedayimani uyathotywa ube ngaphantsi kwesiqingatha sobukhulu bayo bokuqala.

Idatha yovavanyo efunyenwe ngeli xesha ibonisa ukuba amandla e-nano-polycrystalline diamond (NPD) angaphezulu kokuphindwe kabini kwedayimani yekristale enye eqhelekileyo. Kwaye kwafunyaniswa ukuba i-NPD inamandla aphezulu kuzo zonke izixhobo eziphandiweyo ukuza kuthi ga ngoku.
