Hiki i nā mea magnetic hou ke hoʻolilo i nā smartphones i ʻoi aku ka maʻalahi

Ua kapa ʻia nā mea hou he spinel-type high entropy oxides (HEO). Ma ka hoʻohui ʻana i kekahi mau metala i loaʻa maʻamau, e like me ka hao, nickel a me ke kēpau, ua hiki i nā mea noiʻi ke hoʻolālā i nā mea hou me nā waiwai magnetic maikaʻi loa.
ʻO kahi hui i alakaʻi ʻia e ke kaukaʻi kōkua ʻo Alannah Hallas ma ke Kulanui o British Columbia i hoʻomohala a ulu i nā laʻana HEO i kā lākou lab. I ko lākou makemake ʻana i kahi ala e aʻo pono ai i nā mea, ua noi lākou i ka Canadian Light Source (CLS) ma ke Kulanui o Saskatchewan no ke kōkua.
"I ka wā o ke kaʻina hana, e puʻunaue wale ʻia nā mea āpau ma luna o ka ʻōnaehana spinel. Pono mākou i kahi ala e ʻike ai i kahi i loaʻa ai nā mea āpau a pehea lākou i kōkua ai i ka waiwai magnetic o ka mea. ʻO ia kahi i komo ai ka REIXS beamline ma CLS, "wahi a Hallas.
Ua kōkua ka hui i alakaʻi ʻia e ka polopeka o ka physics ʻo Robert Green ma ka U o S i ka papahana ma o ka hoʻohana ʻana i nā kukui X me nā ikaika kūikawā a me nā polarizations e nānā i ka mea a ʻike i nā mea like ʻole.
Ua wehewehe ʻo Green i ka mea hiki ke hana.
"Aia nō mākou i ka wā mua, no laila ʻike ʻia nā noi hou i kēlā me kēia mahina. Hiki ke hoʻohana ʻia kahi magnet maʻalahi no ka hoʻomaikaʻi ʻana i nā loiloi kelepona i ʻole lākou e wela loa a ʻoi aku ka maikaʻi a i ʻole hiki ke hoʻohana ʻia kahi magnet ikaika loa no ka mālama ʻana i ka ʻikepili no ka wā lōʻihi. ʻO ia ka nani o kēia mau mea: hiki iā mākou ke hoʻoponopono iā lākou e kūpono i nā pono ʻoihana kikoʻī.
Wahi a Hallas, ʻo ka pōmaikaʻi nui loa o nā mea hou, ʻo ia ko lākou hiki ke hoʻololi i kahi ʻāpana koʻikoʻi o nā mea ʻenehana honua i hoʻohana ʻia i ka hana ʻenehana.
"Ke nānā ʻoe i ke kumukūʻai maoli o kahi hāmeʻa e like me ke kelepona, ʻo nā mea ʻeleʻele ʻeleʻele i loko o ka pale, ka paʻa paʻa, ka pākaukau, a me nā mea ʻē aʻe ke kumu o ka hapa nui o nā kumukūʻai o kēia mau mea. Hana ʻia nā HEO me ka hoʻohana ʻana i nā mea maʻamau a me ka nui, e hoʻolilo i kā lākou hana ʻoi aku ka maʻalahi a ʻoi aku ka maikaʻi o ke kaiapuni, "wahi a Hallas.
Ke hilinaʻi nei ʻo Hallas e hoʻomaka ana nā mea i kā mākou ʻenehana i kēlā me kēia lā i loko o ʻelima mau makahiki.
