Iqela labaphandi elenziwe ngoogqirha baseRice naseTianjin kwiiyunivesithi lenze nje iintloko emva kokulawula ukuphuhlisa indlela eyahlukileyo yokwenza iityhubhu isentimitha enye kwicala le-graphene e-atomically. Ndiyabulela kolu phando, njengoko sele kugqityiwe, ekugqibeleni umntu wayenokukwazi ukufumana uhlobo lwamandla yenza i-graphene ngobuninzi.
Ngokwamazwi ekhemesti Utyelelo lukaJamesUmbhali-mbhali woxwebhu oluza kuhamba kwihlabathi liphela:
Olu phononongo lolokuqala ngohlobo lwalo. Sibonisile indlela yokwenza igwebu le-graphene ye-3D kwizixhobo zokuqala ezingezizo i-graphene, kwaye indlela iboleka ekulinganisweni ukuya kumagwebu e-graphene kwizicelo zemveliso ezongeziweyo ezinolawulo lobungakanani bepore.
Iqela labaphandi liyakwazi ukuphuhlisa indlela yokwenza igraphene ngesixa esikhulu
Ngoku, ukuvelisa le nto inzima kakhulu Kuba ifuna isikhunta esenziwe kwangaphambili kusetyenziswa inkqubo yoshicilelo ye-3D esekwe kubume bomphunga wamachiza malunga ne-1.000 degrees Celsius kwaye phantse iiyure ezintathu zokufudumeza nokupholisa. Emva kweeyure ezininzi zophando, iqela likwazile ukuhlengahlengisa lo msebenzi ekusebenziseni ubuchule bokushicilela obuqhelekileyo be-3D bokwenza iibhloko ezilingana ngomnwe ze-graphene foam.
Ukuthobela amagama ngale ndlela intsha UJunwei Sha, I-alumnus yelebhu yoKhenketho kunye nomphandi wasemva kobugqirha eTianjin:
Le ndlela ilula nesebenzayo ishenxisa isidingo sokubumba kweendaba ezibandayo kunye nonyango lobushushu obuphezulu. Kuya kufuneka ukuba sisebenzise le nkqubo ukuvelisa iintlobo ezithile zegwebu le-graphene njenge-3D-eprintiweyo eyenziwe ngegrafite, kunye ne-nitrogen kunye nesulfure doped graphene foam, ukutshintsha i-powdor powders.
