Ososayensi bathola ama-magnetic nanopowder ka-6Ubuchwepheshe be-G
I-NewSwise - Ososayensi bezinto ezibonakalayo bathuthukise indlela esheshayo yokukhiqiza i-epsilon iron oxide futhi ikhombise isithembiso sayo samadivayisi okuxhumana ayisizukulwane esilandelayo. Izakhiwo zayo ezivelele ezivelele zenza kube ngenye yezinto zokwakha ezifiselekayo, ezinjengokuthi isizukulwane esingu-6G esizayo samadivayisi wokuxhumana nokuqoshwa kwamandla kazibuthe okuqinile. Umsebenzi wanyatheliswa ejeni lezezimali Chemistry C, iphephabhuku leRoyal Society of Chemistry. I-Iron Oxide (III) ingenye ye-oxides ebanzi kakhulu emhlabeni. Itholakala kakhulu njenge-hematite yamaminerali (noma i-alpha iron oxide, α-FE2O3). Okunye ukuguqulwa okuzinzile futhi okuvamile kungukuguqulwa kwamaMagemite (noma ukuguqulwa kwe-gamma, γ-Fe2o3). Okwedlule kusetshenziswa kabanzi embonini njengengulube ebomvu, kanye nalokhu kamuva njengendlela yokuqopha kazibuthe. Lokhu kuguqulwa okubili kuhlukile hhayi ekwakhiweni kwe-crystalline kuphela (i-alpha-iron oxide ine-hexagonal syngony kanye ne-gamma-iron oxide ine-cubic syngony) kodwa futhi nasezakhiweni zamandla kazibuthe. Ngaphezu kwalezi zinhlobo ze-iron oxide (iii), kunokuguqulwa okungajwayelekile okufana ne-epsilon-, beta-, i-zeta-, ne-ingilazi. Isigaba esikhange kakhulu yi-epsilon iron oxide, ε-FE2O3. Lokhu kuguqulwa kunamandla amakhulu amakhulu (amandla okuqukethwe ukumelana namandla kazibuthe angaphandle). Amandla afinyelela ku-20 koe ekushiseni kwegumbi, okuqhathaniswa namapharamitha kaWounter asuselwa ezintweni ezibizayo zomhlaba. Ngaphezu kwalokho, izinto ezibonakalayo zithola imisebe ye-electromagnetic ebangeni elijwayelekile le-terashettz (100-300 ghz) ngomphumela wokuvuselela okunjalo kwe-ferromagnetic.Imvamisa ukubonwa kwalezi zindlela zokusebenzisa izinto zokuxhumana ezingenantambo - I-4G Standard isebenzisa amashumi eGigahertz. Kunezinhlelo zokusebenzisa ububanzi be-terahertz obusezingeni eliphansi njengobuchwepheshe besizukulwane sesithupha (6G) ubuchwepheshe obungenantambo, obulungiselelwe ukwethulwa okusebenzayo ezimpilweni zethu ezingama-2030. Into ephumayo ilungele ukukhiqizwa kokuguqula amayunithi noma amasekethe angemuva ngalezi ziva. Isibonelo, ngokusebenzisa ama-nanopowders ahlanganisiwe we-Ece-FE2O3 Kuzokwenzeka ukwenza upende odonsa amagagasi e-electromagnetic futhi ngenxa yalokho amakamelo okuvikelwa avela kumakamelo angaphezulu, futhi avikele amasiginali ekuhlukanisweni kwangaphandle. I-ε-FE2O3 uqobo nayo ingasetshenziswa kumadivayisi we-6G wokwamukela. I-Epsilon Iron Oxide iyindlela engajwayelekile kakhulu futhi enzima ye-Iron Oxide ukuthola. Namuhla, kukhiqizwa ngamanani amancane kakhulu, nenqubo ngokwayo ithatha inyanga. Lokhu, yiqiniso, kubusa isicelo saso esisakazekile. Ababhali bocwaningo bahlakulela indlela yokusheshisa okusheshayo kwe-epsilon iron oxide ekwazi ukunciphisa isikhathi sokuhlanganiswa ngolunye usuku (okuwukuthi, ukwenza umjikelezo ogcwele wezikhathi ezingaphezu kwama-30 ngokushesha!) Nokwandisa inani lomkhiqizo ophumelelayo. Le ndlela ilula ukukhiqiza kabusha, ishibhile futhi ingasetshenziswa kalula embonini, futhi izinto zokwakha ezidingekayo ukuze kubumbenguze - insimbi ne-silicon - ziphakathi kwezinto eziningi kakhulu emhlabeni. "Yize isigaba se-epsilon-ironi oxide etholwa ngefomu elihlanzekile ngokuhamba kwesikhathi, ngo-2004, alikatholi uhlelo lwezimboni ngenxa yobulukhuni bokubumbana kwalo, ngokwesibonelo njengendlela yokuqopha kazibuthe - ukuqopha. Sikwazile ukwenza lula ubuchwepheshe, "kusho u-Evgeny Gorbachev, umfundi we-PHD eMnyangweni Wezinto Zesayensi KaMnyango eMoscow State University naseMthethweni wokuqala womsebenzi. Isihluthulelo sokusetshenziswa ngempumelelo kwezinto ezinezimpawu zokuqopha amarekhodi ukucwaninga ngezakhiwo zabo eziyisisekelo zomzimba. Ngaphandle kokutadisha okujulile, lokho okubonakalayo kungakhohlwa ngokungafanele iminyaka eminingi, njengoba kwenzeka kaningi emlandweni wesayensi. Kwakuyi-tandem yezinto zososayensi eMoscow State University, eyahlanganisa i-Compound, kanye nodokotela besayensi eMic, ababeyifunda ngokuningiliziwe, okwenza ukuthuthuka kube yimpumelelo.
