Karbon nanotubave iu gjet njĂ« pĂ«rdorim tjetĂ«r. Disa ditĂ« mĂ« parĂ«, njĂ« artikull nĂ« revistĂ«n Nature Scientific Reports u publikua, ku shqyrtohet pĂ«r herĂ« tĂ« parĂ« mundĂ«sia e pĂ«rdorimit tĂ« nanotubave karbonike me shumĂ« mure (Multiwall carbon nanotubes, MWCNT) nĂ« regjistrimin magnetic nĂ« hard diskĂ«. KĂ«to janĂ« struktura tĂ« ndryshme komplekse CNT si "matryoshka", "skedĂ«" dhe ndĂ«rtime tĂ« tjera. Detyra nĂ« çdo rast pĂ«rqendrohet nĂ« njĂ« gjĂ« - mbushjen e secilĂ«s nanotubĂ« tĂ« tillĂ« komplekse me nanopjesĂ« magnetike. Ădo nanopjesĂ« magnetike e vetme nuk do tĂ« japĂ« efektin e regjistrimit tĂ« tĂ« dhĂ«nave. Ndryshimi i magnetizmit mund tĂ« bĂ«het vetĂ«m me tĂ« gjithĂ« tubin, por kjo do tĂ« jetĂ« akoma mĂ« e dendur se regjistrimi nĂ« njĂ« domain plakĂ« magnetike HDD tĂ« zakonshme. ShumĂ« herĂ« mĂ« e dendur.
Studimi i regjistrimit magnetic nĂ« MWCNT u krye nga shkencĂ«tarĂ«t e Universitetit tĂ« AlaskĂ«s (Fairbanks) dhe disa institucioneve tĂ« tjera kĂ«rkimore nĂ« Shtetet e Bashkuara dhe RepublikĂ«n Ăeke. NjĂ« nga drejtuesit e projektit ishte shkencĂ«tari çeke Gunther Kletetschka. Specialist shpreh se metodat ekzistuese pĂ«r tĂ« rritur densitetin e regjistrimit nĂ« disqet magnetike HDD nuk i pĂ«rgjigjen mĂ« ritmit tĂ« rritjes sĂ« tĂ« dhĂ«nave. PĂ«r tĂ« kontrolluar rritjen e tĂ« dhĂ«nave, Ă«shtĂ« e nevojshme qĂ« densiteti i ruajtjes sĂ« tĂ« dhĂ«nave nĂ« hard diskĂ« tĂ« rritet çdo vit me 40%, ndĂ«rsa vitet e fundit ka pasur njĂ« rritje prej 10â15% nĂ« vit. Regjistrimi duke pĂ«rdorur tubat magnetikĂ« karboni mund tĂ« jetĂ« pĂ«rgjigjja ndaj sfidave tĂ« kohĂ«s informative, por pĂ«r kĂ«tĂ« ende duhen bĂ«rĂ« shumĂ« punĂ« kĂ«rkimore.
The essence of the discovery lies in the fact that carbon nanotubes containing magnetic nanoparticles were subjected to an electromagnetic field of varying amplitude and frequency. The fabrication of nanoparticles-filled carbon tubes was conducted through deposition in a gaseous environmentânothing new here. When a magnetic field was applied at frequencies up to 10 kHz, nothing happened (the surface effect of the conductivity of carbon nanotubes was observed), but as the frequency exceeded 10 kHz and the amplitude of the field decreased, a magnetization effect occurred in the carbon nanotube with magnetic nanoparticles. Scientists believe that the external field matched the magnetic field of the individual particles, allowing the nanotube to achieve stable magnetization in a given direction.
Scientists currently have no proposals on how to create writing and reading mechanisms for recording data on an array of carbon nanotubes, but they promise to work diligently in this area since, over time, data will not decrease.
