Xa abantu baqala ukuthumela iingxowa zetshiphu zetapile kumvelisi, uVaux, ukuqhankqalaza ukuba iingxowa azizange zisetyenziswe ngokulula, inkampani yaphawula oku kwaye yasungula indawo yokuqokelela. Kodwa inyaniso kukuba esi sicwangciso esikhethekileyo sisombulula kuphela inxalenye encinci yentaba yenkunkuma. Rhoqo ngonyaka, iVox Corporation iyodwa ithengisa iibhegi zokupakisha ezizibhiliyoni ezi-4 e-UK, kodwa zizigidi ezi-3 kuphela iingxowa zokupakisha eziphinda zisetyenziswe kule nkqubo ikhankanywe ngasentla, kwaye ayikahlaziywa ngenkqubo yokurisayikilishwa kwendlu.
Ngoku, abaphandi bathi banokuba beze nenye indlela entsha, eluhlaza. Ifilimu yesinyithi esetyenziswa kwiingxowa zokupakisha zeitapile zangoku, imivalo yetshokolethi kunye nokunye ukupakishwa kokutya kuluncedo kakhulu ekugcineni ukutya komile kwaye kupholile, kodwa ngenxa yokuba zenziwe ngamaleko aliqela eplastiki kunye nentsimbi edityanisiweyo kunye, kunzima ukuyibuyisela kwakhona. sebenzisa.
"Ingxowa yetshiphu yeitapile yipakethe yepolymer yobugcisa obuphezulu." utshilo uDermot O'Hare weYunivesithi yaseOxford. Nangona kunjalo, kunzima kakhulu ukuyibuyisela kwakhona.
I-arhente yokulahlwa kwenkunkuma yaseBritane i-WRAP yathi nangona sithetha ngobuchwephesha, iifilimu zentsimbi zinokuphinda zisetyenziswe kwinqanaba lemizi-mveliso, ngokwembono yezoqoqosho, okwangoku akwenzeki ukuba ziphinde zisetyenziswe.
Enye indlela ecetywayo ngu-O'Hare kunye namalungu eqela yifilimu encinci kakhulu ebizwa ngokuba yi-nanosheet. Iqulethwe ngama-amino acids kunye namanzi kwaye inokufakwa kwifilimu yeplastiki (i-polyethylene terephthalate, okanye i-PET, iibhotile zamanzi ezininzi zeplastiki zenziwe nge-PET). Iziphumo eziyeleleneyo zapapashwa kwi-"Nature-Communication" kwiintsuku ezimbalwa ezidlulileyo.
Esi sithako sisisiseko singenabungozi sibonakala sisenza into ekhuselekileyo ekupakishweni kokutya. "Ngokwembono yeekhemikhali, ukusetyenziswa kwezinto ezingenayo ityhefu ukwenza i-nanosheets zokwenziwa kuyimpumelelo." U-O'Hare uthe. Kodwa wathi oku kuya kuhamba kwinkqubo yokulawula ixesha elide, kwaye abantu akufanele balindele ukubona le nto isetyenziswa ekupakisheni ukutya ubuncinane kwiminyaka emi-4.
Inxalenye yomceli mngeni ekuyileni le mathiriyeli kukuhlangabezana neemfuno zeshishini lomqobo olungileyo werhasi ukuthintela ungcoliseko kunye nokugcina imveliso isentsha. Ukwenza i-nanosheets, iqela le-O'Hare lenze "indlela ehlukumezayo", oko kukuthi, ukwakha i-nano-level labyrinth eyenza kube nzima ukuba i-oksijeni kunye nezinye iigesi zisasazeke.
Njengomqobo we-oksijini, ukusebenza kwayo kubonakala malunga namaxesha angama-40 eefilimu ezinqabileyo zetsimbi, kwaye le nto iqhuba kakuhle "kuvavanyo lokugoba" kwishishini. Ifilimu nayo inenzuzo enkulu, oko kukuthi, inye kuphela imathiriyeli ye-PET enokuhlaziywa ngokubanzi.
