Siponji yamagalasi: njira yokhazikika yothetsera kuwonongeka kwa mafuta?

Zithunzi za nyama zam'madzi zomwe zakhala zikusunthidwa kumtunda ndi mafuta ambiri zakhala zikuzungulira pa intaneti kwazaka zambiri. Pali njira zambiri zothanirana ndizowonongeka zomwe zimayambitsa mafuta. Komabe, izi zimakhala njira yodula komanso yovuta. Njira zomwe zikugwiriridwa mpaka pano zimaphatikizaponso kuwotcha mafuta, kugwiritsa ntchito mankhwala omwazika mafuta kudutsa m'mphepete mwa mafuta, kapena kusesa pamadzi. Kuyesayesa kuthetsa vutoli nthawi zambiri kumasokoneza moyo wapamadzi ndipo zinthu zomwe zimagwiritsidwa ntchito kutaya sizingathe kuzikonzanso. 

Kuti athane ndi zotsutsazi, ofufuza ena ochokera ku Northwestern University adasindikiza zotsatira za kafukufuku wawo mu Meyi phunziro zakuwoneka bwino kwa "OHM Sponge" (oelophilic, hydrophobic ndi maginito), kotero kutanthauzira chinkhupule chomwe chimakhala ndi maginito, hydrophobic komanso kukopa mafuta nthawi yomweyo. Chosangalatsa pa lingaliro ili: siponji imatha kuyamwa mpaka katatu maimidwe ndi chinkhupule chake. Mafutawo atakomedwa, siponji imatha kufinyizidwanso ndikutha kuigwiritsanso ntchito pakatha nthawi iliyonse. Zinaonekeranso mu phunziroli kuti siponji imataya mafuta ochepera 30% ngakhale munthawi yamadzi (ngati mafunde amphamvu). Siponji yamagalasi imatha kukhala yothandiza komanso yothandiza pochotsa mafuta.
