Si la mid ah graphene, MXenes waa kaarbiid bir ah oo laba-cabbir ah oo ka kooban lakabyo titanium, aluminium, iyo atamka kaarboon, kuwaas oo mid kastaa leeyahay qaab-dhismeedkiisa deggan oo si fudud u dhex mari kara lakabyada.Bishii Maarso 2021, Jaamacadda Gobolka Missouri ee Sayniska iyo Teknolojiyadda iyo Shaybaadhka Qaranka ee Argonne ayaa cilmi-baaris ku sameeyay agabka MXenes waxayna ogaadeen in dharka-ka-hortagga xirashada iyo saliidda walxahan ee deegaannada aadka u daran ay ka wanaagsan yihiin saliidda dhaqameed ee ku saleysan saliidda, waxaana loo isticmaali karaa sida ""Super Lubricant" si loo yareeyo xirashada baarista mustaqbalka sida Adkeysi.
Cilmi-baadhayaashu waxay ku ekaayeen jawiga booska, iyo tijaabooyinka isku-dhafka ah ee walxaha waxay ogaadeen in isku-dhafka isku-dhafka ah ee is-dhexgalka MXene ee u dhexeeya kubbadda birta iyo saxanka silica-dahaarka leh ee lagu sameeyay "state superlubricated" wuxuu ahaa mid hooseeya sida 0.0067 sida ugu hooseeya 0.0017.Natiijooyin wanaagsan ayaa la helay markii graphene lagu daray MXene.Ku darida graphene waxay sii yareyn kartaa is-jiidhka 37.3% waxayna yareyn kartaa xirashada 2 iyada oo aan saameyn ku yeelan guryaha MXene superlubrication.Qalabka MXenes si fiican ayaa loogu habeeyey jawiga heerkulka sare, furitaanka albaabada cusub ee isticmaalka mustaqbalka ee saliidaha ee jawiga daran.
Horumarka horumarinta chip-ka ugu horreeya ee 2nm ee Maraykanka ayaa lagu dhawaaqay
Caqabadda socota ee warshadaha semiconductor waa in si isku mar ah loo soo saaro microchips yaryar, dhaqso badan, awood badan oo tamar badan leh.Inta badan chips-yada kombuyuutarrada ee aaladaha awooda maanta isticmaala 10- ama 7-nanometer tignoolajiyada geeddi-socodka, iyadoo qaar ka mid ah soosaarayaasha ay soo saaraan chips 5-nanometer ah.
Bishii Maajo 2021, Shirkadda IBM ee Maraykanku waxay ku dhawaaqday horumarka horumarka ee 2nm-kii ugu horreeyay ee hab-socodka adduunka.Chip transistor-ku wuxuu qaataa albaab nanometer saddex-lakab ah oo ku wareegsan naqshadeynta (GAA), iyadoo la adeegsanayo tignoolajiyada ugu horumarsan ee ultraviolet lithography si loo qeexo cabbirka ugu yar, dhererka albaabka transistor waa 12 nanometer, cufnaanta is dhexgalka waxay gaari doontaa 333 milyan halkii milimitir laba jibaaran, 50 bilyanna waa la isku dari karaa.
Transistor-yadu waxa ay ku dhex milmeen aag le'eg ciddida faraha.Marka la barbar dhigo Chip-ka 7nm-ka, 2nm-ka chip-ka ayaa la filayaa inuu kor u qaado waxqabadka 45%, hoos u dhigo isticmaalka tamarta 75%, wuxuuna kordhin karaa cimriga batteriga mobilada afar jeer, taleefanka gacanta ayaa si joogto ah loo isticmaali karaa afar maalmood. hal lacag oo kaliya.
Intaa waxaa dheer, chip-ka cusub wuxuu sidoo kale si weyn u wanaajin karaa waxqabadka kombuyuutarrada buug-yaraha, oo ay ku jiraan hagaajinta awoodda habaynta codsiga ee kombuyuutarrada buug-yaraha iyo xawaaraha helitaanka internetka.Baabuurta iswada, chips-ka 2nm-ku waxay wanaajin karaan awoodaha ogaanshaha shayga waxayna gaabin karaan waqtiyada jawaabta, taas oo si weyn kor ugu qaadi doonta horumarinta goobta semiconductor waxayna sii wadi doontaa halyeeyga Sharciga Moore.IBM waxa ay qorshaynaysaa in ay si balaadhan u soo saarto chips-ka 2nm sanadka 2027.
