Hoʻohui nā honua laha i ka waihoʻoluʻu a me ka ʻālohilohi i nā huahana uila

Ma kekahi mau wahi kahakai, ma muli o ke kuʻi ʻana o ka plankton Bioluminescence i nā nalu, hoʻopuka ke kai i ka pō i kekahi manawa i ke kukui Teal.ʻO nā metala honua laha ʻolehoʻopuka pū i ka mālamalama ke hoʻoulu ʻia, e hoʻohui i ka kala a me ka ʻālohilohi i nā huahana uila. ʻO ka hana hoʻopunipuni, wahi a de Bettencourt Dias, ʻo ia ke ʻokiʻoki i kā lākou f electrons.

Me ka hoʻohana ʻana i nā kumu ikehu e like me nā lasers a i ʻole nā ​​kukui, hiki i nā ʻepekema a me nā ʻenekini ke hoʻohuli i ka f electron i loko o ka honua laha i kahi kūlana hauʻoli a laila hoʻihoʻi iā ia i kahi kūlana dormant, a i ʻole kona ʻāina kumu. "I ka hoʻi ʻana o Lanthanide i ka ʻāina, hoʻopuka lākou i ka mālamalama," wahi āna

Ua ʻōlelo ʻo De Bettencourt Dias: ʻO kēlā me kēia ʻano o ka honua kakaʻikahi e hilinaʻi i ka nalu pololei o ka mālamalama ke hauʻoli. ʻO kēia pololei kūpono e hiki ai i nā ʻenekini ke hoʻoponopono pono i ka radiation electromagnetic i nā huahana uila he nui. ʻO kahi laʻana, ʻo ka lōʻihi o ka hawewe luminescence o terbium ma kahi o 545 nanometer, kahi e kūpono ai ke kūkulu ʻana i nā phosphors ʻōmaʻomaʻo ma ke TV, kamepiula, a me nā pale kelepona. ʻElua mau ʻano maʻamau a Europium a hoʻohana ʻia e kūkulu i nā phosphors ʻulaʻula a me ka uliuli. I ka pōkole, hiki ke hoʻohana ʻia kēia mau phosphors ma nā pale ʻO ka hapa nui o nā kala o ke ānuenue ua kaha ʻia ma ka pale.

Hiki i nā ʻāina laha ʻole ke hoʻopuka i nā kukui ʻike ʻole. ʻO Yttrium ka mea nui o Yttrium alumini garnet a i ʻole YAG. ʻO YAG kahi aniani synthetic, kahi i hoʻokumu i ke kumu o nā lasers mana kiʻekiʻe. Hoʻoponopono nā ʻenekinia i ka lōʻihi o kēia mau lasers ma o ka hoʻohui ʻana i kahi mea ʻē aʻe o ka honua i ka aniani YAG. ʻO ka mea kaulana loa ʻo ka neodymium doped YAG laser, i hoʻohana ʻia no nā kumu like ʻole mai ka ʻoki ʻana i ke kila a hiki i ka wehe ʻana i nā peʻa i ka laser ranging. He koho maikaʻi nā kukuna laser Erbium YAG no ka Minimally invasive kaʻina hana, no ka mea, maʻalahi lākou e komo i ka wai i loko o ke kino, no laila ʻaʻole lākou e ʻoki hohonu.

Ma waho aʻe o nā lasers,lanthanumhe mea nui ia no ka hana ʻana i nā makaaniani infrared i nā aniani ʻike pō. Ua ʻōlelo ʻo Molecular engineer ʻo Tian Zhong mai ke Kulanui o Chicago, "E hoʻokele ʻo Erbium i kā mākou pūnaewele. ʻO ka hapa nui o kā mākou ʻike kikohoʻe e hele ana ma o nā fiber optical i ke ʻano o ka mālamalama me ka lōʻihi o ka hawewe ma kahi o 1550 nanometers - ka lōʻihi like me ka erbium emits. ʻO nā hōʻailona i ka fiber ʻeleʻele nā ​​kaula optic mai ko lākou kumu No ka mea hiki i kēia mau kaula ke hoʻolōʻihi i nā kaukani kilomika ma ke kai, ua hoʻohui ʻia ka erbium i nā fibers e hoʻonui ai i ka hōʻailona.
