Isipanji se-Magnetic: isisombululo esimeme sokungcoliswa kawoyela?

Izithombe zezilwane zasolwandle ebezisakazeke ogwini ngensimbi kawoyela obukhulu bezilokhu zijikeleza i-Intanethi iminyaka eminingi. Kukhona izindlela eziningi zokuqeda umonakalo obangelwa ukungcoliswa kawoyela. Kodwa-ke, lezi kungaba inqubo ebizayo kakhulu futhi eyinkimbinkimbi. Izindlela ezisetshenziswayo kuze kube manje zifaka ukushisa i-oyile, kusetshenziswa amakhemikhali okusabalalisa ukudabula isigaxa sikawoyela, noma ukukhuphuka emanzini. Le mizamo yokuxazulula inkinga ivame ukuphazamisa impilo yasolwandle futhi into esetshenziselwa ukulahla imvamisa ngeke isakwazi ukuziphindaphinda. 

Ukulwa nalokhu kugxekwa, abanye abacwaningi baseNorthwestern University bashicilele imiphumela yocwaningo lwabo ngoMeyi cwaningo mayelana nokusebenza kwe- "OHM Sponge" (i-oelophilic, hydrophobic kanye nozibuthe), ngakho-ke kuhunyushwe isiponji esinamandla kazibuthe, i-hydrophobic neheha uwoyela ngasikhathi sinye. Into enhle ngalo mqondo: isipanji singakwazi ukuthola u-oyili ophindwe izikhathi ezingama-30 kunesisindo sesiponji. Ngemuva kokuthi uwoyela usungenile, isipanji singamane sikhishwe bese siphinda sisetshenziswe ngemuva kokusetshenziswa ngakunye. Kwabuye kwabonwa ocwaningweni ukuthi isipanji selahlekelwe ngaphansi kwama-1% kawoyela obanjiwe ngisho nangaphansi kwezimo zamanzi ezedlulele (njengamagagasi anamandla). Ngakho-ke isipanji sikazibuthe singanikeza enye indlela ephumelelayo neqhubekayo yokususa ukungcoliswa kawoyela.
