No ka hoʻohana ʻana i loko o ka lua puka makani Loaʻa i kā mākou huʻa nickel hou nā pono penei: 1: Kiʻekiʻe ka porosity, ʻoi aku ka nui o ka ʻili kikoʻī o ka mea 2: Māmā ke kaumaha, i ka manawa like hiki ke hoʻokipa i ka omo leo a me ka pale leo 3: ...

He ʻano hou ka huʻa alumini no ke kūkulu hale a me ka hoʻonaninani. Loaʻa iā ia nā pono o ke kaumaha māmā, ke ʻano paʻakikī kiʻekiʻe, ke ʻano nani, ʻaʻole e puhi ʻia, a pēlā aku, a he mau ʻano o ka omo leo, ka pale wela...

Ma ke ʻano he ʻano mea hana hou, ua manaʻo ʻia he mea ʻike ʻole ʻia ka huʻa keleawe e ka poʻe he nui. ʻO ka ʻoiaʻiʻo, hoʻohana nui ka huʻa keleawe i ke keleawe ma ke ʻano he kumu, kahi i hoʻolaha like ʻia ai ka nui o nā lua i hoʻopili ʻia a i ʻole i hoʻokaʻawale ʻia, no laila...

1. He aha kahi mea metala nanoporous? ʻO nā metala Nanoporous (NPM) kahi papa o nā mea metala me nā ligaments interconnected (curvature maikaʻi) a me nā kahawai nanoporous (curvature maikaʻi ʻole), ʻo ka porosity ʻaʻole emi ma lalo o 50%, a...

Ke hoʻomohala nei ka papahana noiʻi EU ʻo Marbel i kahi pākahiko māmā me ka nui o ka ikehu a me nā manawa hoʻouka pōkole e hoʻolalelale i ka hoʻolaha ʻana o nā kaʻa uila ma ka mākeke nui. Manaʻo ka papahana noiʻi EU ʻo Marbel e hoʻomohala i kahi pākahiko māmā...

ʻO ka Photovoltaics, ma ke ʻano he ʻenehana pololei e hoʻololi i ka lā i ka uila, loaʻa iā ia ka hiki ke hoʻoponopono i nā pilikia kaiapuni e hoʻonui mau nei a me ka makemake e hōʻemi i ka hoʻohana ʻana i nā wahie fossil. ʻO ke kūpaʻa wela o ka photovol...

ʻO ka huʻa metala kahi ʻano cellular i hana ʻia me kahi metala paʻa (pinepine alumini) me nā pores i piha i ke kinoea e hana ana i kahi hapa nui o ka leo. Hiki ke sila ʻia nā pores (huʻa cell pani) a i ʻole e hoʻopili ʻia (huʻa cell wehe). ʻO ka de...

Hana ʻia ka huʻa alumini ma ka hoʻohui ʻana i nā mea hoʻohui i ka alumini maʻemaʻe a i ʻole ka hui alumini, a hana ʻia ia ma ke kaʻina hana hoʻohua, a loaʻa iā ia nā ʻano o ka metala a me nā pehu i ka manawa like. He haʻahaʻa kona density, hiki ke hoʻopili i ka hopena kiʻekiʻe, hi...

Manaʻo wau he nui ka poʻe ʻaʻole paha i ʻike i ke ʻano o ia mea ke lohe lākou i ka metala huʻa? ʻO ka ʻoiaʻiʻo, ʻo ka hiʻohiʻona kūikawā o ka huʻa metala ʻo ia kahi mea metala me kahi ʻano kūikawā, a aia kahi ʻano porous me kahi lar...

Ma ke ʻano he ʻano mea metala hou, loaʻa i ka alumini hū nā ʻano o ke kaumaha māmā, ka pale leo, a me ka pale pahū. Hoʻohana nui ʻia ia i ka ʻoihana koa, ka mokulele, ke kūkulu kīwila, a me ke kaʻaahi. Me ka hoʻonui ʻana i kahi...

ʻO ka metala huʻa e pili ana i kahi mea metala kūikawā i loaʻa nā pores huʻa. Ma o kona mau ʻano hoʻonohonoho kūikawā, loaʻa i ka metala huʻa kahi moʻo o nā pono e like me ka haʻahaʻa haʻahaʻa, ka hana pale wela maikaʻi, a me ka pale leo maikaʻi ...

ʻO ka huʻa alumini kahi hui i haku ʻia me nā pehu a me nā diaphragms alumini. ʻO ke ʻano ʻole a me ke ʻano ʻekolu o nā pehu e loaʻa ai nā ʻano maikaʻi loa. A: Māmā ʻO ka mika density o ka huʻa alumini e pili ana i...
