Carbon nanotubes vakawana imwe application. Mazuva mashoma apfuura, imwe nyaya yakabudiswa mujenari Nature Scientific Reports kuti kekutanga yakafunga mukana wekushandisa Multiwall carbon nanotubes (MWCNT) mune magineti kurekodha pane hard drives. Aya ndiwo akasiyana-siyana akaoma CNT zvimiro nenzira ye "matryoshka zvidhori", "convolutions" uye mamwe maitiro. Basa muzviitiko zvese rinouya kuchinhu chimwe - kuisa imwe neimwe yakaoma kabhoni nanotube ine magineti nanoparticles. Imwe neimwe magineti nanoparticle zvakasiyana haigone kuburitsa data yekurekodha maitiro. Iwe unogona chete kushandura magineti yechubhu yese, asi icharamba yakaomesesa pane kunyora magineti domain pane yakajairwa magineti HDD platter. Yakanyanya denser.
Chidzidzo chekurekodha magineti paMWCNT chakaitwa nemasayendisiti kubva kuYunivhesiti yeAlaska (Fairbanks) uye akati wandei mamwe masangano esainzi muUSA neCzech Republic. Mumwe wevatungamiri vepurojekiti aiva musayendisiti weCzech Gunther Kletetschka. Nyanzvi inocherekedza kuti nzira dziripo dzekuwedzera kurekodha density paHDD magineti disks haachaenderane nekumhanya kwekukura kwedata. Kuti udzivise kukura kwedata, kuwanda kwekuchengetedza kwemadhiraivha anofanirwa kukura ne40% gore rega rega, uye mumakore achangopfuura anga achikura ne10-15% pagore. Kurekodha uchishandisa kabhoni magineti machubhu inogona kunge iri mhinduro kumatambudziko ezera reruzivo, asi basa rakakura rekutsvaga richiri kuitirwa izvi.
Izvo zvakakosha zvekuwanikwa ndezvekuti kabhoni nanotubes ine magineti nanoparticles mukati akaoneswa kune emagetsi minda yemaamplitudes akasiyana uye ma frequency akasiyana. Nenzira, kugadzirwa kwekabhoni machubhu akaiswa nanoparticles akaitwa pachishandiswa deposition munzvimbo ine gasi - hapana chitsva. Pakaiswa magineti nefrequency inosvika gumi kHz, hapana chakaitika (iyo yepamusoro mhedzisiro ye conductivity yekabhoni nanotubes yakakanganiswa), asi nekuwedzera kwema frequency pamusoro pe10 kHz uye nekudzikira kwemunda amplitude, mhedzisiro yacho. yemagnetization yekabhoni nanotube ine magineti nanoparticles yakasimuka. Maererano nemasayendisiti, nzvimbo yekunze yakasvika mukubvumirana nemagnetic field yezvimwe zvikamu, izvo zvakaita kuti zvikwanise kupa nanotube yakagadzikana magnetization mune imwe nzira.
Masayendisiti haasati ave nemazano ekuti sei uye sei kugadzira kurekodha uye kuverenga nzira dzekurekodha data pane yakarongwa kabhoni nanotubes, asi vanovimbisa kushanda nemazvo munzira iyi, nekuti nekufamba kwenguva hakuzove ne data shoma.
