Cov kws tshaj lij los ntawm Kaus Lim Qab Teb tau tsim cov cement-raws li cov khoom sib xyaw uas tuaj yeem siv rau hauv cov pob zeb ua cov qauv tsim thiab khaws cov hluav taws xob los ntawm kev cuam tshuam rau cov khoom siv hluav taws xob sab nraud xws li footsteps, cua, nag thiab nthwv dej.
Los ntawm kev hloov cov qauv mus rau hauv cov khoom siv hluav taws xob, cov cement yuav tawg qhov teeb meem ntawm qhov tsim ib puag ncig siv 40% ntawm lub ntiaj teb lub zog, lawv ntseeg.
Cov neeg siv hauv tsev yuav tsum tsis txhob txhawj txog kev raug hluav taws xob.Kev ntsuam xyuas pom tau tias 1% ntim ntawm cov pa roj carbon fiber ntau hauv cov cement sib tov yog txaus los muab cov cement rau cov khoom siv hluav taws xob uas xav tau yam tsis muaj kev cuam tshuam cov qauv kev ua tau zoo, thiab tam sim no tsim tau qis dua qhov siab tshaj plaws tso cai rau tib neeg lub cev.
Cov kws tshawb fawb hauv kev siv tshuab thiab engineering los ntawm Incheon National University, Kyung Hee University thiab Kaus Lim Kauslim University tau tsim cov cement-based conductive composite (CBC) nrog cov roj carbon fibers uas tuaj yeem ua raws li triboelectric nanogenerator (TENG), hom tshuab hluav taws xob tshuab hluav taws xob.
Lawv tau tsim cov qauv ntsuas ntsuas thiab CBC-based capacitor siv cov khoom tsim los sim nws lub zog sau thiab khaws cia.
Seung-Jung Lee, tus xibfwb ntawm Incheon National University Department of Civil and Environmental Engineering hais tias "Peb xav tsim cov khoom siv hluav taws xob uas tuaj yeem siv los tsim cov qauv hluav taws xob xoom xoom uas siv thiab tsim lawv tus kheej hluav taws xob,"
"Vim tias cov cement yog ib qho khoom siv tseem ceeb hauv kev tsim kho, peb tau txiav txim siab siv nws nrog cov khoom siv hluav taws xob ua lub ntsiab lus tseem ceeb rau peb cov kab ke CBC-TENG," nws hais ntxiv.
Cov txiaj ntsig ntawm lawv cov kev tshawb fawb tau luam tawm lub hlis no hauv phau ntawv xov xwm Nano Energy.
Sib nrug los ntawm lub zog khaws cia thiab sau qoob loo, cov khoom siv kuj tseem tuaj yeem siv los tsim cov tshuab ntsuas tus kheej uas saib xyuas cov txheej txheem kev noj qab haus huv thiab kwv yees lub neej kev pabcuam ntxiv ntawm cov vaj tse uas tsis muaj lub zog sab nraud.
"Peb lub hom phiaj kawg yog los tsim cov khoom siv uas ua rau tib neeg lub neej zoo dua thiab tsis xav tau lub zog ntxiv los cawm lub ntiaj teb.Thiab peb cia siab tias qhov kev tshawb pom los ntawm txoj kev tshawb no tuaj yeem siv los nthuav dav CBC raws li cov khoom siv hluav taws xob tag nrho rau cov qauv hluav taws xob xoom, "said Prof. Lee.
Tshaj tawm cov kev tshawb fawb, Incheon National University tau hais tias: "Zoo li kev sib tw pib rau lub ci ntsa iab thiab ntsuab dua tag kis!"
