E like me ka graphene, ʻo MXenes he mea metala carbide ʻelua-dimension i haku ʻia me nā ʻāpana o ka titanium, aluminika, a me nā ʻātoma kalapona, ʻo kēlā me kēia mea nona kona hale paʻa ponoʻī a hiki ke neʻe maʻalahi ma waena o nā papa.Ma Malaki 2021, Missouri State University of Science and Technology a me Argonne National Laboratory i hana i ka noiʻi ʻana i nā mea MXenes a ʻike ʻia ʻoi aku ka maikaʻi o nā waiwai anti-wear a me nā lubricating o kēia mea i nā kaiapuni koʻikoʻi ma mua o nā lubricants maʻamau, a hiki ke hoʻohana ʻia. ""Super Lubricant" e ho'ēmi i kaʻaʻahu i nāʻimi e hiki mai ana e like me Perseverance.
Ua hoʻohālikelike ka poʻe noiʻi i ke kaiapuni ākea, a ua ʻike ʻia nā hoʻāʻo friction o ka mea ʻo ka friction coefficient o ka MXene interface ma waena o ka pōpō kila a me ka silica-coated disc i hoʻokumu ʻia i ka "superlubricated state" he haʻahaʻa e like me 0.0067 me 0.0017.Loaʻa nā hopena maikaʻi i ka wā i hoʻohui ʻia ai ka graphene i MXene.Hiki i ka hoʻohui ʻana i ka graphene ke hōʻemi hou i ka friction e 37.3% a hoʻemi i ka ʻaʻahu ma kahi helu o 2 me ka ʻole o ka hoʻopili ʻana i nā waiwai superlubrication MXene.Hoʻopili maikaʻi ʻia nā mea MXenes i nā wahi wela kiʻekiʻe, e wehe ana i nā puka hou no ka hoʻohana ʻana i nā lubricants i ka wā e hiki mai ana i nā kaiapuni koʻikoʻi.
Ua hoʻolaha ʻia ka holomua ʻana o ka chip kaʻina hana 2nm mua ma ʻAmelika Hui Pū ʻIa
ʻO kahi paʻakikī e hoʻomau nei i ka ʻoihana semiconductor e hana like i nā microchips liʻiliʻi, wikiwiki, ikaika a ʻoi aku ka ikehu.ʻO ka hapa nui o nā mīkini kamepiula e hoʻohana ana i nā mīkini i kēia lā i ka ʻenehana kaʻina hana 10- a i ʻole 7-nanometer, me kekahi mau mea hana e hana ana i nā chips 5-nanometer.
I Mei 2021, ua hoʻolaha ʻo IBM Corporation o ʻAmelika i ka holomua o ka hoʻomohala ʻana o ka chip kaʻina hana 2nm mua o ka honua.Hoʻohana ka chip transistor i kahi hoʻolālā nanometer ʻekolu-layer a puni (GAA), me ka hoʻohana ʻana i ka ʻenehana lithography ultraviolet kiʻekiʻe loa e wehewehe i ka liʻiliʻi liʻiliʻi, ʻo ka lōʻihi o ka puka transistor he 12 nanometers, ʻo ka nui o ka hoʻohui ʻana e hiki i 333 miliona no kēlā me kēia square millimeter, a hiki i ka 50 billion ke hoʻohui.
Hoʻohui ʻia nā transistors ma kahi ʻāpana e like me ka nui o ka manamana lima.Ke hoʻohālikelike ʻia me ka chip 7nm, manaʻo ʻia ka hoʻomaikaʻi ʻana o ka chip kaʻina hana 2nm e 45%, e hōʻemi i ka hoʻohana ʻana i ka ikehu e 75%, a hiki ke hoʻonui i ke ola pākaukau o nā kelepona paʻa i ʻehā mau manawa, a hiki ke hoʻohana mau ʻia ke kelepona paʻa no nā lā ʻehā. me ka uku hookahi.
Eia hou, hiki i ka chip kaʻina hana hou ke hoʻomaikaʻi nui i ka hana o nā kamepiula puke, me ka hoʻomaikaʻi ʻana i ka mana hana noi o nā kamepiula puke puke a me ka wikiwiki o ka loaʻa ʻana o ka Pūnaewele.Ma nā kaʻa kaʻa kaʻa ponoʻī, hiki i nā ʻāpana kaʻina hana 2nm ke hoʻomaikaʻi i ka hiki ke ʻike i nā mea a hoʻopōkole i nā manawa pane, kahi e hoʻoikaika nui ai i ka hoʻomohala ʻana o ke kahua semiconductor a hoʻomau i ka moʻolelo o Moore's Law.Hoʻolālā ʻo IBM e hana nui i nā pahu kaʻina hana 2nm i 2027.
