lāʻau ʻōlinolino

ʻO ka hoʻohana ʻana i ka lāʻau māmā i ke kūkulu ʻana a me nā ʻōnaehana uila

ʻO ka lāʻau he mea ikaika a maʻalahi hoʻi ka hale, akā e like me nā mea āpau, aia kona mau drawbacks (ʻo ia ka pala i ka manawa, palaho mai nā pōpoki a poloka i ka hele ʻana o ka mālamalama).

ʻAʻole ʻoi aku ka maikaʻi o nā pā aniani maʻamau. Hoʻololi maʻalahi lākou i ka mālamalama a hāʻawi i ka nui o ka ikehu e kahe i loko a i waho paha o ka hale. Ua loaʻa i nā ʻenekinia ka maikaʻi o nā mea ʻelua: lāʻau ʻālohilohi.

ʻO nā kānaka ʻepekema ʻo Liangbing Hu, ʻo Dr. Ua hoʻokō ʻo Mingwei Zhu a me kā lākou mau hoa hana mai ke Kulanui o Maryland i ka hana ʻana i kahi poloka lāʻau i akaka, no laila e loaʻa ai kahi mea hiki ke hoʻohana ʻia i ke kūkulu ʻana a me nā ʻōnaehana uila e pili ana i ka mālamalama.

Ua wehe ka poʻe ʻepekema mai ka lāʻau i ka mole e ʻoʻoleʻa a ʻeleʻele hoʻi ka waihoʻoluʻu, a loaʻa i nā hale cellulose kala ʻole o ka cellulose i hoʻopiha ʻia me ka resin epoxy, no laila e hana ana i ka lāʻau i ʻike ʻia.

"Hiki ke hoʻohana ʻia kēia i loko o nā kaʻa no ka mea ʻo ka lāʻau he akaka a ikaika loa," wahi a Dr. ʻO Zhu, ka mea kākau mua o ka haʻawina. "Hiki iā ʻoe ke hoʻohana iā ia ma ke ʻano he mea hale kūʻokoʻa."

Ma ka wehe ʻana i ka pena a me nā mea kemika, lilo ka lāʻau i ʻike, akā ʻoi aku ka ikaika a ʻoi aku ka maikaʻi o ka insulator ma mua o ke aniani, a ʻoi aku ka maikaʻi o ka biodegradability ma mua o ka plastic.

Ua hoʻomaka ke kaʻina hana i hoʻoheheʻe ʻia ka lāʻau ma ka hoʻolapalapa ʻana i ka wai i hui pū ʻia me ka sodium hydroxide a me nā mea kemika ʻē aʻe no 2 mau hola. Ua hoʻokahe kēia i ka lignin, ka mole e hāʻawi i ka lāʻau i kona kala, mai loko mai o ka lāʻau. Ma hope o kēlā, ninini lākou i ka resin epoxy ma luna o ka ʻāpana lāʻau, ʻo ia ka mea i ʻoi aku ka ikaika o ʻehā a ʻelima.

ʻO kekahi o nā mea hoihoi o ka lāʻau "hou" ʻo ia ka mālama ʻana i ke ʻano a me nā ala kūlohelohe i hana ʻia i ka wā he lāʻau "maoli". Hiki i kēia mau microchannels ke alakaʻi i ka māmā e like me kā lākou hana ʻana i nā meaʻai ma ke ʻano o kahi mea kanu. "Ma ka mea kahiko, ua laha ka malamalama," wahi a Hu. "Inā loaʻa iā ʻoe kēlā hopena i ka lāʻau, e hiki mai ana ka mālamalama i loko o kou hale."

Ma nā ʻano noiʻi e hiki mai ana, e hoʻāʻo ka poʻe ʻepekema e hoʻomohala i kahi ʻenehana e hiki ai iā lākou ke hoʻonui i kēia ʻenehana, i hiki iā lākou ke hana i nā poloka nui o ka lāʻau aniani e hoʻohana ʻia no nā kumu like ʻole mai ka hana ʻana i nā puka makani, nā mea hale a me nā lako. , ke ala a pau i nā noi liʻiliʻi e like me nā lako optics pololei i hana mau ʻia me ke aniani a i ʻole ka plastic.
