Ososayensi Bathola I-Magnetic Nanopowder ye-6G Technology
I-Newswise - Ososayensi bezinto ezibonakalayo baye basungula indlela esheshayo yokukhiqiza i-epsilon iron oxide futhi babonisa isithembiso sayo semishini yezokuxhumana yesizukulwane esilandelayo. Izakhiwo zayo ezivelele kazibuthe ziyenza ibe enye yezinto ezifiseleka kakhulu, njengesizukulwane esizayo se-6G yemishini yokuxhumana kanye nokuqoshwa okuqinile kazibuthe. Umsebenzi washicilelwa kuJournal of Materials Chemistry C, iphephabhuku leRoyal Society of Chemistry. I-iron oxide (III) ingenye yama-oxide asakazeke kakhulu emhlabeni. Itholakala kakhulu njenge-mineral hematite (noma i-alpha iron oxide, α-Fe2O3). Okunye ukuguqulwa okuzinzile nokujwayelekile yi-maghemite (noma ukuguqulwa kwe-gamma, γ-Fe2O3). Owokuqala usetshenziswa kakhulu embonini njenge-pigment ebomvu, kanti lena yakamuva njengendawo yokurekhoda kazibuthe. Lezi zinguquko ezimbili azihlukani kuphela ngesakhiwo se-crystalline (i-alpha-iron oxide ine-syngony ene-hexagonal kanye ne-gamma-iron oxide ine-cubic syngony) kodwa futhi nasezicini kazibuthe. Ngaphezu kwalezi zinhlobo ze-iron oxide (III), kukhona ukuguqulwa okungavamile okufana ne-epsilon-, i-beta-, i-zeta-, ngisho nengilazi. Isigaba esikhanga kakhulu i-epsilon iron oxide, ε-Fe2O3. Lokhu kuguqulwa kunamandla aphoqelelayo aphezulu kakhulu (ikhono lempahla yokumelana nenkundla kazibuthe yangaphandle). Amandla afinyelela ku-20 kOe ekamelweni lokushisa, eliqhathaniswa nemingcele yamagnethi ngokusekelwe ezintweni ezibizayo eziyivelakancane zomhlaba. Ngaphezu kwalokho, i-material imunca imisebe ye-electromagnetic ku-sub-terahertz frequency range (100-300 GHz) ngomthelela we-ferromagnetic resonance yemvelo. okujwayelekile kusebenzisa i-megahertz kanti i-5G isebenzisa amashumi e-gigahertz. Kunezinhlelo zokusebenzisa uhla lwe-sub-terahertz njengohlu olusebenzayo kubuchwepheshe obungenawaya besizukulwane sesithupha (6G), obulungiselelwa ukwethulwa okusebenzayo ezimpilweni zethu kusukela ekuqaleni kwawo-2030. Impahla ewumphumela ifanele ukukhiqizwa kwamayunithi aguqulayo noma amasekhethi okumunca kulawa maza. Isibonelo, ngokusebenzisa inhlanganisela ε-Fe2O3 nanopowder kuzokwazi ukwenza opende abamunca amagagasi kazibuthe futhi ngaleyo ndlela kuvikelwe amagumbi kumasignali angaphandle, futhi kuvikelwe amasignali ekunqamukeni ngaphandle. I-ε-Fe2O3 ngokwayo ingasetshenziswa futhi kumadivayisi wokwamukela we-6G. I-Epsilon iron oxide iwuhlobo olungavamile kakhulu futhi olunzima lwe-iron oxide ukutholakala. Namuhla, ikhiqizwa ngamanani amancane kakhulu, inqubo ngokwayo ithatha inyanga. Lokhu, vele, akukhiphi ukusetshenziswa kwayo okusabalele. Ababhali bocwaningo bathuthukise indlela yokusheshisa ukuhlanganiswa kwe-epsilon iron oxide ekwazi ukunciphisa isikhathi sokuhlanganisa ibe usuku olulodwa (okungukuthi, ukwenza umjikelezo ogcwele ngokushesha okungaphezu kwezikhathi ezingama-30!) . Le nqubo ilula ukukhiqiza kabusha, ishibhile futhi ingasetshenziswa kalula embonini, futhi izinto ezidingekayo ukuze kuhlanganiswe - insimbi ne-silicon - ziphakathi kwezakhi eziningi kakhulu eMhlabeni. “Nakuba isigaba se-epsilon-iron oxide satholwa sisesimweni esimsulwa kudala, ngo-2004, asikakasitholi isicelo sezimboni ngenxa yobunkimbinkimbi bokuhlanganisa kwayo, isibonelo njengendawo yokuqopha kazibuthe. Sikwazile ukwenza ubuchwepheshe bube lula kakhulu,” kusho u-Evgeny Gorbachev, umfundi we-PhD eMnyangweni Wezesayensi Yezinto Zokusebenza e-Moscow State University nombhali wokuqala walo msebenzi. Isihluthulelo sokusetshenziswa ngempumelelo kwezinto ezinezici zokwephula irekhodi ucwaningo lwezakhiwo zazo eziyisisekelo. Ngaphandle kokucwaninga okujulile, ukwaziswa kungase kukhohlakale ngokungafanele iminyaka eminingi, njengoba kuye kwenzeka izikhathi ezingaphezu kwesisodwa emlandweni wesayensi. Kwakuyi-tandem yososayensi bezinto zokwakha e-Moscow State University, abahlanganisa i-compound, kanye ne-physicists e-MIPT, abayifunda ngokuningiliziwe, okwenza ukuthuthukiswa kwaba yimpumelelo.
