Mainjiniya ochokera ku South Korea apanga chinthu chopangidwa ndi simenti chomwe chingagwiritsidwe ntchito mu konkire kuti apange nyumba zomwe zimapanga ndikusunga magetsi kudzera mu mphamvu zakunja monga mapazi, mphepo, mvula ndi mafunde.
Akukhulupirira kuti posintha nyumba kukhala magwero amagetsi, simenti idzathetsa vuto la malo omangidwa omwe amagwiritsa ntchito 40% ya mphamvu zapadziko lonse lapansi.
Ogwiritsa ntchito nyumba sayenera kuda nkhawa kuti agwidwa ndi magetsi. Mayeso adawonetsa kuti voliyumu ya 1% ya ulusi wa kaboni woyendetsa mu simenti yosakaniza inali yokwanira kupatsa simenti mphamvu zamagetsi zomwe amafunikira popanda kusokoneza magwiridwe antchito a kapangidwe kake, ndipo mphamvu yopangidwa inali yotsika kwambiri kuposa mulingo wovomerezeka wa thupi la munthu.
Ofufuza za uinjiniya wamakina ndi zomangamanga ochokera ku Incheon National University, Kyung Hee University ndi Korea University adapanga chopangira mphamvu chopangidwa ndi simenti (CBC) chokhala ndi ulusi wa kaboni chomwe chingathenso kugwira ntchito ngati triboelectric nanogenerator (TENG), mtundu wa chokolola mphamvu chamakina.
Anapanga kapangidwe ka labu ndi capacitor yochokera ku CBC pogwiritsa ntchito zipangizo zomwe adapanga kuti ayesere mphamvu zake zokolola ndi kusunga.
"Tinkafuna kupanga zinthu zamagetsi zomwe zingagwiritsidwe ntchito popanga nyumba zamagetsi zomwe zimagwiritsa ntchito ndikupanga magetsi awoawo," anatero Seung-Jung Lee, pulofesa mu Dipatimenti ya Uinjiniya wa Zachilengedwe ndi Zachilengedwe ku Incheon National University.
"Popeza simenti ndi chinthu chofunikira kwambiri pa ntchito yomanga, tinaganiza zogwiritsa ntchito ndi ma conductive fillers ngati chinthu chachikulu choyendetsera ntchito yathu ya CBC-TENG," adatero.
Zotsatira za kafukufuku wawo zinasindikizidwa mwezi uno mu magazini ya Nano Energy.
Kupatula kusungira ndi kukolola mphamvu, zinthuzo zingagwiritsidwenso ntchito popanga makina odziwonera okha omwe amayang'anira thanzi la kapangidwe kake ndikulosera nthawi yotsala ya ntchito ya zomangamanga za konkriti popanda mphamvu yakunja.
"Cholinga chathu chachikulu chinali kupanga zinthu zomwe zimapangitsa miyoyo ya anthu kukhala yabwino komanso zosafunikira mphamvu zina zowonjezera kuti apulumutse dziko lapansi. Ndipo tikuyembekeza kuti zomwe zapezeka mu kafukufukuyu zitha kugwiritsidwa ntchito kukulitsa kugwiritsa ntchito kwa CBC ngati mphamvu zonse muzinthu zonse zamagetsi," adatero Pulofesa Lee.
Pofalitsa kafukufukuyu, Incheon National University inaseka kuti: “Zikuoneka ngati chiyambi chosangalatsa cha mawa lowala komanso lobiriwira!”
