I-Carbon nanotubes ithole olunye uhlelo lokusebenza. Ezinsukwini ezimbalwa ezedlule, i-athikili yanyatheliswa kumagazini i-Nature Scientific Reports ukuthi ngokokuqala ngqΓ‘ kucatshangelwe ukuthi kungenzeka ukusebenzisa i-Multiwall carbon nanotubes (MWCNT) ekurekhodeni kazibuthe kuma-hard drive. Lezi yizinhlobonhlobo zezakhiwo ze-CNT eziyinkimbinkimbi ngendlela "yonodoli be-matryoshka", "convolutions" nezinye izakhiwo. Umsebenzi kuzo zonke izimo wehlela entweni eyodwa - ukufaka ikhabhoni ngayinye eyinkimbinkimbi nanotube ngama-nanoparticles azibuthe. I-nanoparticle ngayinye kazibuthe ngokwehlukana ngeke ikhiqize umphumela wokuqopha idatha. Ungashintsha kuphela ukudonsa uzibuthe weshubhu lonke, kodwa lisazoba minyene kunokubhala isizinda kazibuthe ocwecweni olujwayelekile lukazibuthe lwe-HDD. I-denser kakhulu.
Ucwaningo lokuqoshwa kazibuthe ku-MWCNT lwenziwa ososayensi base-University of Alaska (Fairbanks) kanye nenani lezinye izikhungo zesayensi e-USA nase-Czech Republic. Omunye wabaholi bephrojekthi kwakungusosayensi waseCzech uGunther Kletetschka. Uchwepheshe uphawula ukuthi izindlela ezikhona zokukhulisa ukuminyana kokurekhoda kumadiski kazibuthe e-HDD azisahambisani nesivinini sokukhula kwedatha. Ukunqanda ukukhula kwedatha, ukuminyana kokugcinwa kwama-hard drive kudinga ukukhula ngo-40% njalo ngonyaka, futhi eminyakeni yamuva nje bekulokhu kukhula ngo-10-15% ngonyaka. Ukurekhoda kusetshenziswa amashubhu kazibuthe ekhabhoni kungase kube yimpendulo ezinseleleni zeminyaka yolwazi, kodwa umsebenzi omkhulu wocwaningo kusamele wenziwe kulokhu.
Ingqikithi yokutholwa ukuthi ama-carbon nanotubes anama-nanoparticles kazibuthe ngaphakathi avezwe ezinkambini ze-electromagnetic zama-amplitudes ahlukene namafrikhwensi ahlukene. Ngendlela, ukukhiqizwa kwamashubhu ekhabhoni agcwele ama-nanoparticles kwenziwa kusetshenziswa ukufakwa endaweni enegesi - akukho okusha. Lapho kusetshenziswa inkambu kazibuthe enemvamisa efinyelela ku-10 kHz, akwenzekanga lutho (umphumela ongaphezulu we-conductivity ye-carbon nanotubes ethintekile), kodwa ngokunyuka kwemvamisa engaphezu kuka-10 kHz kanye nokuncipha kwe-amplitude yasensimini, umphumela kwavela i-magnetization ye-carbon nanotube enama-nanoparticles kazibuthe. Ngokusho kososayensi, insimu yangaphandle yavumelana nensimu yamagnetic yezinhlayiya ngazinye, okwenza kube nokwenzeka ukunikeza i-nanotube magnetization ezinzile endaweni ethile.
Ososayensi abakabi nazo iziphakamiso zokuthi zingakha kanjani futhi kanjani izindlela zokurekhoda nokufunda zokurekhoda idatha kuhlu lwama-carbon nanotubes, kodwa bathembisa ukusebenza kahle kulokhu, ngoba ngokuhamba kwesikhathi ngeke kube nedatha encane.
