Faka kungobo yomlando: Umbhalo ulondoloza ngokwethembeka izimangalo ezivela ku-athikili yoqobo futhi awusona isiqinisekiso sazo esisha sochwepheshe. Ucwaningo oluchaziwe, inqubo, impahla kanye nezicelo ezingase zibe khona akuwona umkhiqizo, ukucaciswa kobuchwepheshe, isitifiketi noma iphrojekthi ye-Savo Kusić. Ukunikezwa komphakathi kwamanje kugxile kumafasitela neminyango yangokwezifiso.
Incazelo yomlando yocwaningo
Ukhuni luyimpahla yokwakha eqinile futhi eguquguqukayo, kodwa njenganoma iyiphi into, inezihibe zayo (iyabola ngokuhamba kwesikhathi, ibole ngenxa yeziphazamisi futhi ivimbe ukudlula kokukhanya).
Amaphaneli engilazi ajwayelekile awangcono kakhulu. Bahlehlisa kalula ukukhanya futhi bavumele inani elikhulu lamandla ukuthi ligeleze lingene noma liphume esakhiweni. Onjiniyela bathole okuhle kakhulu kukho kokubili: ukhuni olukhanyayo.
Ososayensi uLiangbing Hu, uDkt. Mingwei Zhu kanye nozakwabo abavela eNyuvesi yaseMaryland bakwazile ukwenza ibhulokhi yokhuni ikhanye, ngaleyo ndlela bathola into engasetshenziswa ekwakheni nasezinhlelweni zikagesi ezisekelwe ekukhanyeni.
Ososayensi bakhiphe okhunini i-molecule elenza liqine futhi libe mnyama ngombala, futhi bathola izakhiwo zeseli ezingenambala ze-cellulose ezigcwele i-epoxy resin, ngaleyo ndlela kubangele ukhuni olubonisa ngale.
“Lokhu kungasetshenziswa ezimotweni ngoba izinkuni zombili zisobala futhi zinamandla kakhulu,” kusho uDkt. Zhu, umbhali wokuqala wocwaningo. “Ungayisebenzisa futhi njengempahla yokwakha ehlukile.”
Ngokususa upende namakhemikhali, ukhuni lube sobala, kodwa futhi luqinile futhi luyisivikelo esingcono kunengilazi, futhi lunendawo yokubola kangcono kunepulasitiki.
Inqubo nezakhiwo ezishiwo esihlokweni
Inqubo eyenza ukhuni lukhanye iqale ngokulubilisa emanzini ahlanganiswe ne-sodium hydroxide namanye amakhemikhali cishe amahora angu-2. Lokhu kwakhipha i-lignin, i-molecule eyenza ukhuni lube nombala walo, luphume okhunini. Ngemva kwalokho, bathela inhlaka ye-epoxy phezu kokhuni, okwayenza yaqina ngokuphindwe kane kuya kahlanu.
Enye yezinto ezithokozisayo zokhuni “olusha” ukuthi lugcine ukwakheka namashaneli emvelo akhiwe ngenkathi lulukhuni “lwangempela”. Lawa ma-microchannel angakwazi ukuhambisa ukukhanya njengoba enza imisoco njengengxenye yesitshalo. “Ezintweni zendabuko, ukukhanya kuhlakazekile,” kusho uHu. “Uma uthola lowo mphumela okhunini, ukukhanya okwengeziwe kuzongena endlini yakho.”
Izinhlelo zokusebenza ezingenzeka ezisohlwini lomthombo
Ezigabeni ezilandelayo zocwaningo, ososayensi bazozama ukwenza indlela ezobavumela ukuthi balinganise lobu buchwepheshe, ukuze kukhiqizwe amabhulokhi amakhulu okhuni olubonisa izinto ezosetshenziselwa izinjongo ezihlukahlukene kusukela ekwenzeni amawindi, izinto zokwakha kanye nefenisha, yonke indlela ukuya ezintweni ezincane ezifana nemishini yokubona enembayo evame ukwenziwa ngengilazi noma ngepulasitiki.
