Ngokufanayo ne-graphene, i-MXenes iyinsimbi ye-carbide enezinhlangothi ezimbili ezakhiwe ngezingqimba ze-titanium, i-aluminium, nama-athomu e-carbon, ngayinye enesakhiwo sayo esizinzile futhi esingahamba kalula phakathi kwezingqimba. NgoMashi 2021, i-Missouri State University of Science and Technology kanye ne-Argonne National Laboratory yenze ucwaningo ngezinto ze-MXenes futhi yathola ukuthi izinto ezilwa nokugqokwa nokugcoba zale nto ezindaweni eziyingozi zingcono kunamafutha endabuko asuselwa kuwoyela, futhi angasetshenziswa njenge "I-"Super Lubricant" yokunciphisa ukuguga kuma-probes azayo njenge-Perseverance.
Abacwaningi balingisa imvelo yesikhala, futhi ukuhlolwa kokungqubuzana kwento etholakalayo kwathola ukuthi i-coefficient yokungqubuzana yesixhumi esibonakalayo se-MXene phakathi kwebhola lensimbi ne-silica-coated disc eyakhiwe "kusimo se-superlubricated" yayiphansi njenge-0.0067 iphansi njengo-0.0017. Imiphumela engcono yatholwa lapho i-graphene yengezwa ku-MXene. Ukwengezwa kwe-graphene kungaqhubeka nokunciphisa ukungqubuzana ngo-37.3% futhi kunciphise ukuguga ngesici esingu-2 ngaphandle kokuphazamisa izakhiwo ze-MXene superlubrication. Izinto ze-MXenes zivumelane kahle nezimo eziphakeme zokushisa, zivula iminyango emisha ukuze kusetshenziswe amafutha okuthambisa esikhathini esizayo ezindaweni ezimbi kakhulu.
Inqubekelaphambili yokuthuthukiswa kwe-chip yokuqala ye-2nm e-United States imenyezelwe
Inselele eqhubekayo embonini ye-semiconductor ukwenza ngesikhathi esisodwa ama-microchips amancane, asheshayo, anamandla kakhulu futhi awonga amandla. Ama-chip amaningi ekhompiyutha asebenzisa amandla namuhla asebenzisa ubuchwepheshe benqubo ye-nanometer eyi-10 noma engu-7, abanye abakhiqizi bakhiqiza ama-chips angama-nanometer angu-5.
NgoMeyi 2021, i-IBM Corporation yase-United States yamemezela inqubekelaphambili yentuthuko ye-chip yokuqala ye-2nm yomhlaba. I-chip transistor ithatha isango le-nanometer elinezingqimba ezintathu nxazonke (i-GAA), isebenzisa ubuchwepheshe obuphezulu kakhulu be-ultraviolet lithography ukuchaza usayizi omncane, ubude besango le-transistor ngama-nanometer angu-12, ukuminyana kokuhlanganiswa kuzofinyelela ku-333 million ngemilimitha yesikwele, kanti izigidigidi ezingama-50 zingahlanganiswa.
Ama-transistors ahlanganiswe endaweni elingana nozipho lomunwe. Uma kuqhathaniswa ne-7nm chip, i-2nm process chip kulindeleke ukuthi ithuthukise ukusebenza ngo-45%, inciphise ukusetshenziswa kwamandla ngo-75%, futhi inganweba impilo yebhethri yomakhalekhukhwini izikhathi ezine, futhi umakhalekhukhwini ungasetshenziswa ngokuqhubekayo izinsuku ezine. ngenkokhiso eyodwa kuphela.
Ngaphezu kwalokho, i-chip yenqubo entsha ingaphinde ithuthukise kakhulu ukusebenza kwamakhompiyutha e-notebook, okuhlanganisa nokwenza ngcono amandla okucubungula izinhlelo zokusebenza zamakhompiyutha we-notebook kanye nesivinini sokufinyelela ku-inthanethi. Ezimotweni ezizishayelayo, ama-chips e-2nm process angathuthukisa amandla okuthola into futhi afinyeze izikhathi zokuphendula, okuzothuthukisa kakhulu ukuthuthukiswa kwenkambu ye-semiconductor futhi kuqhubeke inganekwane yoMthetho ka-Moore. I-IBM ihlela ukukhiqiza ngobuningi be-2nm process chips ngo-2027.
