Dị ka graphene, MXenes bụ ihe nwere akụkụ abụọ nke carbide metal nke nwere akwa titanium, aluminom na carbon carbon, nke ọ bụla nwere usoro kwụsiri ike nke ya ma nwee ike ịgafe n'etiti akwa. Na Machị 2021, Mahadum Sayensị na Nkà na Ụzụ nke Missouri na Argonne National Laboratory mere nyocha na ihe MXenes wee chọpụta na mgbochi iyi na mmanu mmanu nke ihe a na gburugburu ebe dị oke mma ka mma mmanu sitere na mmanụ ọdịnala, enwere ike iji ya dịka ""Super lubricant" iji belata iyi na nyocha n'ọdịnihu dị ka nnọgidesi ike.
Ndị na-eme nchọpụta simulated gburugburu oghere, na esemokwu esemokwu nke ihe onwunwe chọpụtara na esemokwu esemokwu nke MXene interface n'etiti blọlụ nchara na silica-coated disc kpụrụ na "superlubricated steeti" dị ka 0.0067 dị ala dị ka 0.0017. Enwetara nsonaazụ ka mma mgbe etinyere graphene na MXene. Mgbakwunye nke graphene nwere ike ibelata esemokwu site na 37.3% wee belata iyi site na nkeji 2 na-enweghị emetụta MXene superlubrication Njirimara. A na-emezi ihe MXenes nke ọma na gburugburu ebe okpomọkụ dị elu, na-emeghe ọnụ ụzọ ọhụrụ maka iji mmanụ mmanu mee n'ọdịnihu na gburugburu ebe dị oke egwu.
A mara ọkwa ọganihu mmepe nke mgbawa usoro 2nm mbụ na United States
Ihe ịma aka na-aga n'ihu na ụlọ ọrụ semiconductor bụ imepụta obere microchips dị obere, ngwa ngwa, dị ike na ike karịa. Ọtụtụ ibe kọmputa ndị na-enye ngwaọrụ taa na-eji teknụzụ usoro 10- na 7-nanometer, ebe ụfọdụ ndị na-emepụta ihe na-emepụta ibe 5-nanometer.
Na Mee 2021, ụlọ ọrụ IBM nke United States kwupụtara ọganihu mmepe nke mgbawa usoro 2nm mbụ n'ụwa. The mgbawa transistor nakweere ọnụ ụzọ nanometer atọ oyi akwa gburugburu (GAA) imewe, na-eji kasị elu ultraviolet lithography technology na-akọwa nke kacha nta size, transistor ọnụ ụzọ ámá ogologo bụ 12 nanometers, mbanye njupụta ga-eru 333 nde kwa square millimeter. na ijeri 50 nwere ike jikọta.
A na-ejikọta transistor na mpaghara nha ntu aka. E jiri ya tụnyere mgbawa 7nm, a na-atụ anya mgbawa usoro 2nm ga-eme ka arụmọrụ ya dịkwuo mma site na 45%, belata oriri ume site na 75%, ma nwee ike ịgbatị ndụ batrị nke ekwentị mkpanaaka ugboro anọ, yana enwere ike iji ekwentị mkpanaaka na-aga n'ihu ruo ụbọchị anọ. na naanị otu ụgwọ.
Na mgbakwunye, mgbawa usoro ọhụrụ ahụ nwekwara ike imeziwanye arụmọrụ nke kọmpụta akwụkwọ ndetu, gụnyere imeziwanye ike nhazi ngwa nke kọmpụta akwụkwọ ndetu yana ọsọ nke ịnweta ịntanetị. N'ime ụgbọ ala ndị na-anya onwe ha, ibe usoro 2nm nwere ike imeziwanye ikike ịchọpụta ihe ma belata oge nzaghachi, nke ga-akwalite mmepe nke ubi semiconductor ma gaa n'ihu na akụkọ ifo nke Iwu Moore. IBM na-ezube imepụta ibe usoro 2nm na 2027.
