Cov kws ua vaj tse los ntawm Kaus Lim Qab Teb tau tsim cov khoom sib xyaw ua los ntawm cov cement uas siv tau rau hauv cov pob zeb ua vaj tse los ua cov qauv uas tsim thiab khaws hluav taws xob los ntawm kev raug rau cov khoom siv hluav taws xob sab nraud xws li kev taug kev, cua, nag thiab nthwv dej.
Los ntawm kev hloov cov qauv mus ua cov chaw muab hluav taws xob, cov cement yuav daws qhov teeb meem ntawm qhov chaw tsim kho uas siv 40% ntawm lub zog thoob ntiaj teb, lawv ntseeg.
Cov neeg siv tsev tsis tas yuav txhawj txog kev raug hluav taws xob tua. Kev sim qhia tau tias 1% ntawm cov roj carbon fiber conductive hauv cov cement sib tov txaus kom muab cov cement cov khoom hluav taws xob xav tau yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm cov qauv, thiab cov hluav taws xob tsim tawm qis dua qib siab tshaj plaws rau tib neeg lub cev.
Cov kws tshawb fawb hauv kev tsim kho tshuab thiab kev tsim kho pej xeem los ntawm Incheon National University, Kyung Hee University thiab Korea University tau tsim cov khoom sib xyaw ua ke (CBC) uas muaj cov roj carbon fibers uas kuj tuaj yeem ua haujlwm ua triboelectric nanogenerator (TENG), ib hom khoom siv hluav taws xob.
Lawv tau tsim ib lub qauv ntsuas hauv chav kuaj thiab lub capacitor raws li CBC siv cov khoom tsim los sim nws lub peev xwm sau qoob loo thiab khaws cia lub zog.
"Peb xav tsim cov khoom siv hluav taws xob uas siv tau los tsim cov qauv hluav taws xob uas tsis muaj zog ntau thiab siv thiab tsim lawv tus kheej lub zog hluav taws xob," Seung-Jung Lee, tus xibfwb hauv Incheon National University's Department of Civil and Environmental Engineering hais.
"Vim tias cov cement yog ib yam khoom siv tsim kho uas tseem ceeb heev, peb tau txiav txim siab siv nws nrog cov khoom siv conductive ua lub hauv paus tseem ceeb rau peb lub kaw lus CBC-TENG," nws hais ntxiv.
Cov txiaj ntsig ntawm lawv txoj kev tshawb fawb tau luam tawm lub hlis no hauv phau ntawv xov xwm Nano Energy.
Sib nrug ntawm kev khaws cia lub zog thiab kev sau qoob loo, cov khoom siv kuj tseem siv tau los tsim cov kab ke uas pom tau tus kheej uas saib xyuas kev noj qab haus huv ntawm cov qauv thiab kwv yees lub neej ua haujlwm ntawm cov qauv pob zeb uas tseem tshuav yam tsis muaj zog sab nraud.
"Peb lub hom phiaj kawg yog tsim cov ntaub ntawv uas ua rau tib neeg lub neej zoo dua thiab tsis tas yuav muaj zog ntxiv los cawm lub ntiaj teb. Thiab peb xav tias cov kev tshawb pom los ntawm txoj kev tshawb fawb no tuaj yeem siv los nthuav dav kev siv CBC ua cov khoom siv hluav taws xob rau cov qauv hluav taws xob xoom, "said Prof. Lee.
Thaum tshaj tawm qhov kev tshawb fawb no, Incheon National University tau hais tso dag tias: "Zoo li yog qhov pib zoo rau tag kis uas ci ntsa iab thiab ntsuab dua!"
