Mofanana ndi graphene, MXenes ndi zitsulo za carbide ziwiri-dimensional zomwe zimapangidwa ndi titaniyamu, aluminiyamu, ndi maatomu a carbon, omwe ali ndi mawonekedwe ake okhazikika ndipo amatha kuyenda mosavuta pakati pa zigawo.Mu Marichi 2021, Missouri State University of Science and Technology ndi Argonne National Laboratory idachita kafukufuku pa zida za MXenes ndipo idapeza kuti zotsutsana ndi kuvala ndi zopaka mafuta zamtunduwu m'malo owopsa ndizabwino kuposa mafuta opangira mafuta, ndipo atha kugwiritsidwa ntchito ngati "Super Lubricant" kuti muchepetse kuvala pazoyeserera zam'tsogolo monga Kupirira.
Ofufuzawo anayerekezera malo a mlengalenga, ndipo mayesero a mkangano a zinthuzo adapeza kuti kugunda kwachitsulo kwa mawonekedwe a MXene pakati pa mpira wachitsulo ndi chimbale chopangidwa ndi silika chomwe chinapangidwa mu "boma lopangidwa ndi superlubricated" chinali chochepa ngati 0.0067 chotsika ngati 0.0017.Zotsatira zabwino zinapezedwa pamene graphene inawonjezeredwa ku MXene.Kuwonjezera kwa graphene kungathe kuchepetsa kukangana ndi 37.3% ndi kuchepetsa kuvala ndi chinthu cha 2 popanda kukhudza MXene superlubrication katundu.Zida za MXenes zimasinthidwa bwino kumadera otentha kwambiri, kutsegula zitseko zatsopano zogwiritsira ntchito mafuta m'tsogolomu m'madera ovuta kwambiri.
Kupita patsogolo kwa chipangizo choyambirira cha 2nm ku United States kudalengezedwa
Vuto lomwe likupitilira mumakampani a semiconductor ndikupanga munthawi yomweyo ma microchips ang'onoang'ono, othamanga, amphamvu komanso osapatsa mphamvu.Makina ambiri apakompyuta omwe zida zamagetsi masiku ano zimagwiritsa ntchito ukadaulo wa 10- kapena 7-nanometer, pomwe opanga ena amapanga tchipisi ta 5-nanometer.
Mu Meyi 2021, IBM Corporation yaku United States idalengeza zakupita patsogolo kwa chipangizo choyambirira cha 2nm padziko lapansi.Chip transistor utenga atatu wosanjikiza chipata nanometer kuzungulira (GAA) kapangidwe, ntchito apamwamba kwambiri ultraviolet lithography luso kufotokoza kukula osachepera, transistor pachipata kutalika ndi 12 nanometers, kachulukidwe kaphatikizidwe adzafika 333 miliyoni pa lalikulu millimeter, ndipo 50 biliyoni akhoza kuphatikizidwa.
Ma transistors amaphatikizidwa m'dera la kukula kwa msomali.Poyerekeza ndi chipangizo cha 7nm, chipangizo cha 2nm chikuyembekezeka kupititsa patsogolo ntchito ndi 45%, kuchepetsa kugwiritsa ntchito mphamvu ndi 75%, ndipo chikhoza kuwonjezera moyo wa batri wa mafoni a m'manja ndi kanayi, ndipo foni yam'manja ingagwiritsidwe ntchito mosalekeza kwa masiku anayi. ndi mtengo umodzi wokha.
Komanso, latsopano ndondomeko Chip angathenso bwino kwambiri ntchito makompyuta kope, kuphatikizapo kuwongolera ntchito processing mphamvu ya makompyuta kope ndi liwiro la intaneti.M'magalimoto odziyendetsa okha, tchipisi cha 2nm chimatha kukulitsa luso lozindikira zinthu ndikufupikitsa nthawi yoyankha, zomwe zingalimbikitse kukula kwa gawo la semiconductor ndikupitiliza nthano ya Chilamulo cha Moore.IBM ikukonzekera kupanga tchipisi ta 2nm mu 2027.
