Iqembu labaphenyi elenziwe odokotela baseRice naseTianjin University lisanda kuba sematheni ngemuva kokuphatha ukwenza inqubo eyingqayizivele yokwenza amakhilogremu isentimitha elilodwa ohlangothini lwe-graphene ezondile. Ngenxa yalolu cwaningo, njengoba sekuphothuliwe, ekugcineni umuntu ubengakwazi ukuthola uhlobo lwamandla yenza i-graphene ngobuningi.
Ngokwamazwi kasokhemisi Ukuvakasha kukaJames, umbhali osebenza naye wedokhumenti ezungeza umhlaba wonke:
Lolu cwaningo ngolokuqala kohlobo lwalo. Sikhombise ukuthi zenziwa kanjani amagwebu e-graphene e-3D ezintweni zokuqala ezingasetshenziswanga, futhi indlela izenza ikhuphuke iye kumagwebu e-graphene ezinhlelo zokusebenza zokukhiqiza ezenezwayo ezilawulwa ngosayizi wepore.
Iqembu labacwaningi likwazi ukusungula indlela yokwenza i-graphene ngobuningi
Kulungile manje ukukhiqiza le nto kuyinkimbinkimbi kakhulu ngoba idinga isikhunta esenziwe ngaphambilini kusetshenziswa inqubo yokuphrinta ye-3D ngokususelwa ekubekeni umhwamuko wamakhemikhali cishe ku-1.000 3 degrees Celsius futhi cishe amahora amathathu okushisa nokupholisa. Ngemuva kwamahora amaningi ocwaningo, iqembu likwazile ukuvumelanisa lo msebenzi nokusetshenziswa kwendlela ejwayelekile yokuphrinta ye-XNUMXD yokwenza amabhlogo alinganayo ngomunwe we-graphene foam.
Ukulalela amagama ngale ndlela entsha ye UJunwei Sha, i-alumnus yelebhu yeTour nomcwaningi osemuva kokufundela eTianjin:
Le ndlela elula nephumelelayo iqeda isidingo sokubanda komshini wokubanda kanye nokwelashwa okushisa okuphezulu. Kufanele futhi sikwazi ukusebenzisa le nqubo ukukhiqiza izinhlobo ezithile ze-foam ye-graphene efana ne-3D-ephrintiwe i-graphite lukathayela, kanye ne-nitrogen nesulfure doped graphene foam, ukushintsha izimpushana zangaphambi kokufika.
