Amafilimu ekhabhoni anjenge-graphene alula kakhulu kodwa izinto eziqinile kakhulu ezinekhono lesicelo elihle kakhulu, kepha kungaba nzima ukukhiqiza, kuvame ukudinga amasu amaningi amahle kanye nezindlela ezidliwayo zemvelo.
Ngomkhiqizo wenani elikhulu le-grapheene, ukuze unqobe ubunzima obuhlangabezana nalo ekusebenziseni izindlela zamanje zokukhishwa, abacwaningi eBen Gurion Universion of ALDEL azosetshenziswa ezinhlotsheni ezahlukahlukene zama-neev, kufaka phakathi i-Optics, i-Electronics, I-Ecology kanye ne-Biotechnology.
Abaphenyi basebenzise ukuhlakazeka kwemishini ukukhipha i-graphene kusuka ku-strilite yemvelo yemvelo. Bathole ukuthi i-hypophyllite yamaminerali ibonisa amathuba amahle ekwakhiweni kwe-graphe ye-Industrial-Scale kanye nezinto ezifana ne-graphe.
Okuqukethwe yikhabhoni ye-hypomphibole kungenzeka kwehlukile. Ngokusho kokuqukethwe kwekhabhoni, i-hypomphibole ingaba namandla ahlukile wohlelo lokusebenza. Ezinye izinhlobo zingasetshenziselwa izakhiwo zazo ze-catalytic, kuyilapho ezinye izinhlobo zinezakhiwo ze-bactericidal.
Izici ezihlelekile ze-hypopyroxene zinquma uhlelo lwazo kwinqubo yokunciphisa i-oxidation, futhi futhi lungasetshenziselwa ukukhiqizwa kokukhiqizwa komlilo kanye nokukhiqizwa kwe-FerrolAlloy ye-Cast (High Silicon) Insimbi.
Ngenxa yezakhiwo zayo ezingokomzimba nezemishini, ubuningi obuningi, amandla amahle kanye nokuvimbela ukugqokwa, i-hypophyllite futhi inamandla ku-adderb izinto ezahlukahlukene ze-organic, ngakho-ke ingasetshenziswa njengento yokuhlunga. Iphinde ikhombise amandla okususa izinhlayiya zamahhala ezinamandla ezingangcolisa imithombo yamanzi.
I-hypopyroxene ibonisa amandla okubulala amagciwane futhi ihlanze amanzi avela kumagciwane, ama-spores, ama-microorganisms alula kanye ne-algae eluhlaza okwesibhakabhaka. Ngenxa ye-catalytic yayo ephezulu futhi enciphisa izakhiwo, ama-magnesia avame ukusetshenziswa njenge-adsorbent yokwelashwa kwamanzi amdaka.

I-Graphene Extraction
Ukulungiselela amadwala okukhishwa kwe-graphene, laba bobabili basebenzise i-elektroni microscope (SEM) ukuhlola ukungcola okusindayo kwensimbi kanye ne-porusity emasandleni. Baphinde basebenzise ezinye izindlela zelebhu ukubheka ukwakheka okujwayelekile kwezakhiwo kanye nokuba khona kwamanye amaminerali ase-Hypomphibole.
Ngemuva kokuhlaziywa kwesampula nokulungiselela kwaqedwa, abacwaningi bakwazile ukukhipha i-graine kusuka eDiorite ngemuva kokucubungula isampula eKarelia esebenzisa umshini wokuhlanza wedijithali.
Njengoba inani elikhulu lamasampula lingacutshungulwa kusetshenziswa le ndlela, alikho ubungozi bokungcoliswa kwesibili, nezindlela zokufaka isampula ezalandela azidingeki.
Njengoba izakhiwo ezingejwayelekile ze-grapheneene zizaziwa kabanzi emphakathini obanzi wesayensi, ukukhiqizwa okuningi kanye nezindlela zokuhlanganisa kuye kwathuthukiswa. Kodwa-ke, eziningi zalezi zindlela ziyizindlela ezingenazinyathelo ezahlukahlukene noma zidinga ukusetshenziswa kwamakhemikhali kanye no-oxidizing onamandla kanye nokunciphisa ama-ejenti.
Yize i-graphene namanye amafilimu e-carbon akhombise khona amandla amakhulu okusebenza futhi athole impumelelo ye-R & D ehlobene, izinqubo ezisebenzisa lezi zinto zisakhiwa. Ingxenye yenselelo ukwenza ukukhishwa kwe-graphene kubiza kakhulu, okusho ukuthi ukuthola ubuchwepheshe obufanele bokusakaza kuyisihluthulelo.
Lokhu kuhlakazeka noma indlela yokudideka kuyasebenza nangobungane nemvelo, futhi amandla abuchwepheshe nawo angadala amaphutha ku-graphene ekhiqizwayo, ngaleyo ndlela anciphise ikhwalithi enhle ye-grapheene.
Ukusetshenziswa kwabahlanzi be-ultrasonic ekuhlolweni kwe-graphene kuqeda ubungozi nezindleko ezihambisana nezindlela eziningi zezinyathelo nezinyathelo zamakhemikhali. Ukusebenzisa le ndlela kwi-hypophyllite yemvelo yemvelo yaveza indlela yendlela entsha yemvelo yokukhiqiza i-graphene.
