Otu nyocha nke mejupụtara nwa akwụkwọ Ph.D Kento Katairi na Onye Mmekọ Prọfesọ Masayoshi Ozaki nke Ụlọ Akwụkwọ Gụsịrị Akwụkwọ nke Engineering, Mahadum Osaka, Japan, na Prọfesọ Toruo Iriya sitere na Ụlọ Ọrụ Nnyocha maka Deep Earth Dynamics nke Mahadum Ehime, na ndị ọzọ, akọwawo ike nke nano-polycrystalline diamond n'oge nrụrụ dị elu.

Ndị otu nyocha ahụ kpalitere kristal nwere oke iri puku nanometers iji mepụta diamond na steeti “nanopolycrystalline” wee tinye ya nnukwu nrụgide ka ọ nyochaa ike ya. Emere nnwale ahụ site na iji laser XII laser nwere ike mmepụta mkpụrụ akụ kacha ukwuu na Japan. Nleba anya chọpụtara na mgbe a na-etinye nrụgide kachasị elu nke 16 nde ikuku (ihe karịrị ugboro 4 nrụgide nke etiti ụwa), ụda diamond na-ebelata ihe na-erughị ọkara nke nha mbụ ya.

Data nnwale enwetara oge a na-egosi na ike nke nano-polycrystalline diamond (NPD) karịrị okpukpu abụọ karịa nke otu diamond kristal nkịtị. Achọpụtakwara na NPD nwere ike kachasị elu n'etiti ihe niile a nyochara ugbu a.
