Ho tšoana le graphene, MXenes ke tšepe ea carbide e nang le mahlakore a mabeli e entsoeng ka likarolo tsa titanium, aluminium le liathomo tsa carbon, e 'ngoe le e' ngoe e na le sebopeho sa eona se tsitsitseng 'me e ka tsamaea habonolo pakeng tsa lihlopha.Ka March 2021, Missouri State University of Science and Technology le Argonne National Laboratory li ile tsa etsa lipatlisiso ka thepa ea MXenes 'me ea fumana hore thepa e khahlanong le ho roala le ho tlotsa ea thepa ena libakeng tse feteletseng e molemo ho feta mafura a tloaelehileng a thehiloeng ka oli,' me a ka sebelisoa e le "Super Lubricant" ho fokotsa ts'ebetso ea li-probes tse tlang joalo ka Mamello.
Bafuputsi ba ile ba etsisa tikoloho ea sebaka, 'me liteko tsa likhohlano tsa thepa li fumane hore motsoako oa likhohlano oa sebopeho sa MXene pakeng tsa bolo ea tšepe le disk e entsoeng ka silica e entsoeng ka "superlubricated state" e ne e le tlaase ho 0.0067 e le tlase ho 0.0017.Liphetho tse ntle li ile tsa fumanoa ha graphene e kenngoa ho MXene.Ho eketsoa ha graphene ho ka fokotsa likhohlano ka 37.3% le ho fokotsa ho roala ka karolo ea 2 ntle le ho ama thepa ea MXene superlubrication.Lisebelisoa tsa MXenes li ikamahanya hantle le maemo a mocheso o phahameng, ho bula mamati a macha bakeng sa tšebeliso ea nakong e tlang ea lubricant libakeng tse feteletseng.
Khatelo-pele ea nts'etsopele ea chip ea pele ea 2nm United States e phatlalalitsoe
Phephetso e ntseng e tsoela pele indastering ea semiconductor ke ho etsa ka nako e le 'ngoe li-microchips tse nyane, tse potlakileng, tse matla le tse baballang matla.Boholo ba lisebelisoa tsa khomphutha tse sebelisang matla kajeno li sebelisa theknoloji ea ts'ebetso ea 10- kapa 7-nanometer, 'me bahlahisi ba bang ba hlahisa li-chips tsa 5-nanometer.
Ka Mots'eanong 2021, IBM Corporation ea United States e phatlalalitse tsoelopele ea nts'etsopele ea chip ea pele ea lefats'e ea 2nm.The chip transistor e nka moralo oa heke ea nanometer e nang le likarolo tse tharo ho potoloha (GAA), e sebelisa theknoloji e tsoetseng pele ka ho fetesisa ea ultraviolet ho hlalosa boholo ba bonyane, bolelele ba heke ea transistor ke li-nanometer tse 12, boima ba ho kopanya bo tla fihla ho limilione tse 333 ka millimeter e le 'ngoe, mme tse dibilione tse 50 di ka kopanngwa.
Li-transistors li kopantsoe sebakeng sa boholo ba lenala.Ha ho bapisoa le chip ea 7nm, chip ea 2nm e lebelletsoe ho ntlafatsa ts'ebetso ka 45%, ho fokotsa tšebeliso ea matla ka 75%, 'me e ka lelefatsa bophelo ba betri ea mehala ea thekeng ka makhetlo a mane,' me mohala oa thekeng o ka sebelisoa khafetsa ka matsatsi a mane. ka tefiso e le nngwe feela.
Ho phaella moo, chip e ncha ea ts'ebetso e ka boela ea ntlafatsa haholo ts'ebetso ea lik'homphieutha tsa libuka, ho kenyelletsa le ho ntlafatsa matla a ts'ebetso ea kopo ea lik'homphieutha tsa libuka le lebelo la ho kena Inthaneteng.Likoloi tse itsamaisang, li-chips tsa 2nm process li ka ntlafatsa bokhoni ba ho lemoha ntho le ho khutsufatsa linako tsa karabelo, tse tla khothaletsa nts'etsopele ea lebala la semiconductor le ho ntšetsa pele tšōmo ea Molao oa Moore.IBM e rera ho hlahisa li-chips tsa 2nm ka bongata ka 2027.
