Zvakafanana negraphene, MXenes isimbi carbide maviri-dimensional material inoumbwa nematanda etitanium, aruminiyamu, uye maatomu ecarbon, imwe neimwe ine chimiro chayo chakagadzikana uye inogona kufamba nyore pakati pezvikamu.Muna Kurume 2021, Missouri State University yeScience neTekinoroji neArgonne National Laboratory yakaita tsvakiridzo pazvinhu zveMXenes ndokuona kuti anti-kupfeka nekuzora zvinhu zvechinhu ichi munzvimbo dzakanyanyisa zviri nani pane mafuta echinyakare-based lubricant, uye anogona kushandiswa se ""Super Lubricant" kuderedza kupfeka pane ramangwana probes seKutsungirira.
Vatsvakurudzi vakafananidza nzvimbo yepakati, uye kuedza kwekukwesha kwezvinhu kwakawana kuti friction coefficient yeMXene interface pakati pesimbi yesimbi uye silica-coated disc yakagadzirwa mu "superlubricated state" yakanga yakaderera se0.0067 yakaderera se0.0017.Migumisiro iri nani yakawanikwa apo graphene yakawedzerwa kuMXene.Kuwedzerwa kwegraphene kunogona kuwedzera kudzikisa kupokana ne37.3% uye kuderedza kusakara nechikamu che2 pasina kukanganisa MXene superlubrication zvivakwa.MXenes zvinhu zvakagadziridzwa zvakanaka kune yakanyanya tembiricha nharaunda, kuvhura mikova mitsva yekushandisa mune ramangwana remafuta munzvimbo dzakanyanyisa.
Kufambira mberi kwekusimudzira kwekutanga 2nm process chip muUnited States yakaziviswa
Dambudziko ririkuenderera mberi muindasitiri yesemiconductor nderekugadzira panguva imwe chete madiki, anokurumidza, ane simba uye anowedzera simba-anoshanda mamicrochips.Mazhinji machipisi emakombuta ayo ane magetsi madhiza nhasi anoshandisa gumi- kana 7-nanometer process tekinoroji, nevamwe vagadziri vachigadzira 5-nanometer machipisi.
Muna Chivabvu 2021, IBM Corporation yekuUnited States yakazivisa kufambira mberi kweiyo yekutanga 2nm process chip.Iyo chip transistor inotora matatu-layer nanometer gedhi kumativi ese (GAA) dhizaini, ichishandisa yakanyanya kunyanyisa ultraviolet lithography tekinoroji kutsanangura hushoma saizi, iyo transistor gedhi kureba ndeye gumi nemaviri nanometers, kusanganisa kwekubatanidza kuchasvika 333 miriyoni pa square millimeter, uye 50 bhiriyoni inogona kubatanidzwa.
Iyo transistors inosanganiswa munzvimbo yakaenzana neminwe.Kana ichienzaniswa ne7nm chip, iyo 2nm process chip inotarisirwa kuvandudza mashandiro ne45%, kuderedza kushandiswa kwesimba ne75%, uye inogona kuwedzera hupenyu hwebhatiri hwenharembozha kanokwana kana, uye nharembozha inogona kushandiswa nguva dzose kwemazuva mana. nemhosva imwe chete.
Pamusoro pezvo, iyo itsva process chip inogona zvakare kuvandudza zvakanyanya mashandiro emakomputa emabhuku, kusanganisira kuvandudza simba rekushandisa rekushandisa renotibook makomputa uye kumhanya kweInternet.Mumotokari dzinozvityaira, 2nm process chips inogona kuvandudza kugona kwechinhu uye kupfupisa nguva dzekupindura, izvo zvinosimudzira zvakanyanya kusimudzira kwemunda wesemiconductor uye kuenderera nengano yeMutemo waMoore.IBM inoronga kuburitsa 2nm process chips muna 2027.
