As nanotubes made of carbon find yet another application. A few days ago, an article was published in the journal Nature Scientific Reports, which for the first time examines the possibility of using multi-walled carbon nanotubes (Multiwall carbon nanotubes, MWCNT) in magnetic recording on hard drives. These are various complex CNT structures in the shape of \"matryoshkas,\" \"scrolls,\" and other constructions. The task in all cases boils down to one: to fill each such complex carbon nanotube with magnetic nanoparticles. Each individual magnetic nanoparticle will not provide data recording effect. Magnetization can only be changed for the entire tube, but it will still be denser than simply recording magnetically. o dom\u00ednio<\/a> HDD comum. Muito mais denso.<\/p>\n

\"Nanotubos<\/p>\n

O estudo sobre grava\u00e7\u00e3o magn\u00e9tica em MWCNT foi realizado por cientistas da Universidade do Estado do Alasca (Fairbanks) e de outras institui\u00e7\u00f5es cient\u00edficas nos EUA e na Rep\u00fablica Tcheca<\/a>One of the project leaders is Czech scientist Gunther Kletetschka. The expert notes that existing methods for increasing recording density on HDD magnetic disks no longer meet the speed of data growth. To tame the growth of data, the density of data storage on hard drives must increase by 40% each year, whereas in recent years it has only been growing by 10\u201315% annually. Recording using carbon magnetic tubes may provide answers to the challenges of the information age, but monumental research work still lies ahead.<\/p>\n

A ess\u00eancia da abertura \u00e9 que nanotubos de carbono com part\u00edculas magn\u00e9ticas internas foram submetidos a um campo eletromagn\u00e9tico de diferentes amplitudes e frequ\u00eancias. A fabrica\u00e7\u00e3o de nanotubos recheados com part\u00edculas foi, ali\u00e1s, realizada por meio de deposi\u00e7\u00e3o em um ambiente gasoso - nada de novo. Com a aplica\u00e7\u00e3o de um campo magn\u00e9tico com frequ\u00eancia de at\u00e9 10 kHz, nada aconteceu (o efeito superficial da condutividade dos nanotubos de carbono se manifestou), mas \u00e0 medida que a frequ\u00eancia aumentava al\u00e9m de 10 kHz e com a diminui\u00e7\u00e3o da amplitude do campo, o efeito de magnetiza\u00e7\u00e3o do nanotubo de carbono com part\u00edculas magn\u00e9ticas surgia. Segundo os cientistas, o campo externo se alinhava com o campo magn\u00e9tico das part\u00edculas individuais, permitindo que o nanotubo tivesse uma magnetiza\u00e7\u00e3o est\u00e1vel em uma dire\u00e7\u00e3o especificada.<\/p>\n

\"Nanotubos<\/p>\n

Os cientistas ainda n\u00e3o t\u00eam propostas sobre como criar mecanismos de grava\u00e7\u00e3o e leitura para armazenar dados em um array de nanotubos de carbono, mas prometeram trabalhar bem nessa dire\u00e7\u00e3o, uma vez que, com o tempo, os dados n\u00e3o v\u00e3o diminuir.<\/p>\n
