Inqaku le-Archive: Umbhalo ugcina ngokuthembekileyo amabango avela kwinqaku lokuqala kwaye ayisosiqinisekiso sabo sengcali entsha. Uphando oluchaziweyo, inkqubo, izinto eziphathekayo kunye nezicelo ezinokwenzeka azikho imveliso, inkcazo yobugcisa, isatifikethi okanye iprojekthi yeSavo Kusić. Unikezelo lwangoku lukawonke-wonke lugxile kwifestile yesiqhelo kunye neengcango.
Inkcazo ngokwembali yophando
Ukhuni sisixhobo sokwakha esomeleleyo kwaye sisebenza ngeendlela ezininzi, kodwa njengayo nayiphi na into, inemiqobo yayo (iyabola ngokuhamba kwexesha, ibole kwiibhugi kwaye ivale ukudlula kokukhanya).
Iipaneli zeglasi eziqhelekileyo azikho ngcono kakhulu. Bajika ngokulula ukukhanya kwaye bavumela isixa esikhulu samandla ukuba singene okanye siphume kwisakhiwo. Iinjineli zifumene okona kulungileyo kuzo zombini: umthi ocacileyo.
Izazinzulu uLiangbing Hu, uGqr. Mingwei Zhu kunye noogxa babo abavela kwiYunivesithi yaseMaryland bakwazile ukwenza ibhloko yomthi ecacileyo, ngaloo ndlela bafumana izinto ezinokusetyenziswa ekwakhiweni nakwiinkqubo zombane ezisekelwe ekukhanyeni.
Izazinzulu ziye zasusa emthini imolekyuli eyenza ukuba yomelele kwaye ibe mnyama ngombala, kwaye zafumana izakhiwo zeeseli ezingenambala zeselulosi ezizaliswe yi-epoxy resin, nto leyo ibangele umthi obonakala ngokucacileyo.
“Oku kunokusetyenziswa kwiimoto kuba iinkuni zombini zibonakala kwaye zinamandla kakhulu,” kusho uDkt Zhu, umbhali wokuqala wokufunda. “Ungayisebenzisa njengesixhobo sokwakha esisodwa.”
Ngokususa ipeyinti kunye neekhemikhali, iinkuni ziye zabonakala, kodwa zomelele kwaye zisisigqubuthelo esingcono kuneglasi, kwaye zinepropathi yokonakala kwezinto eziphilayo kuneplastiki.
Inkqubo kunye nezakhiwo ezikhankanywe kwinqaku
Inkqubo eyenza ukhuni lubonakale luqala ngokubiliswa emanzini axutywe nesodium hydroxide kunye nezinye iikhemikhali malunga neeyure 2. Oku kukhupha i-lignin, imolekyuli enika umthi umbala wayo, ngaphandle komthi. Emva koko, bagalela i-epoxy resin phezu kwebhloko yomthi, eyenze ukuba yomelele ngokuphindwe kane ukuya kahlanu.
Enye yezinto ezinomdla zomthi “omtsha” kukuba igcine ubume kunye nemijelo yendalo eyenziwe xa yayiyinkuni “yokwenene”. Le mijelo mincinci inokuqhuba ukukhanya njengokuba iqhuba izondlo njengenxalenye yesityalo. “Kwizinto zemveli, ukukhanya kuthe saa,” utshilo uHu. “Ukuba ufumana loo mphumela emthini, ukukhanya okungakumbi kuya kungena endlwini yakho.”
izicelo ezinokwenzeka zidweliswe kumthombo
Kumanqanaba alandelayo ophando, izazinzulu ziya kuzama ukuphuhlisa ubuchule obuya kubavumela ukuba balinganise obu buchwepheshe, ukuze kuveliswe iibhloko ezinkulu zomthi ocacileyo eziya kuthi zisetyenziselwe iinjongo ezahlukeneyo ukusuka ekwenzeni iifestile, izinto zokwakha kunye nefenitshala, yonke indlela ukuya kwizicelo ezincinci ezifana nezixhobo ezichanekileyo zokukhanya ezihlala zenziwe ngeglasi okanye iplastiki.
