Iifilim zekhabhoni ezifana negraphene zikhaphukhaphu kakhulu kodwa zizixhobo zomelele kakhulu ezinesakhono sesicelo esigqwesileyo, kodwa kunokuba nzima ukwenziwa, ngokuqhelekileyo zifuna abasebenzi abaninzi kunye nezicwangciso ezithatha ixesha, kwaye iindlela zibiza kakhulu kwaye azikho kwimeko engqongileyo.
Ngokuveliswa komthamo omkhulu wegraphene, ukuze unqobe ubunzima obujongene nokuphunyezwa kweendlela zangoku zokukhutshwa, abaphandi beYunivesithi yaseBen Gurion yaseNegev kwaSirayeli baye baphuhlisa indlela yokukhutshwa kwegraphene "eluhlaza" enokuthi isetyenziswe kuluhlu olubanzi. yemimandla, kubandakanywa i-optics, i-electronics, i-ikholoji kunye ne-biotechnology.
Abaphandi basebenzise ukusasazwa koomatshini ukukhupha igraphene kwimineral striolite yendalo.Bafumanise ukuba i-mineral hypophyllite ibonisa amathuba amahle ekuveliseni i-industrial-scale graphene kunye nezinto ezifana negraphene.
Umxholo wekhabhoni we-hypomphibole unokuhluka.Ngokomxholo wekhabhoni, i-hypomphibole ingaba neendlela ezahlukeneyo zokusebenzisa.Ezinye iintlobo zinokusetyenziselwa iipropathi zazo ze-catalytic, ngelixa ezinye iintlobo zineempawu ze-bactericidal.
Iimpawu zesakhiwo se-hypopyroxene zinquma ukusetyenziswa kwazo kwinkqubo yokunciphisa i-oxidation, kwaye ingasetyenziselwa ukuveliswa kwesithando somlilo kunye nokuveliswa kwe-ferroalloy ye-cast (i-silicon ephezulu) yentsimbi.
Ngenxa yeempawu zayo ezibonakalayo kunye noomatshini, ubuninzi bobuninzi, amandla afanelekileyo kunye nokunganyangeki, i-hypophyllite nayo inamandla okubhengeza iindidi zezinto eziphilayo, ngoko inokusetyenziswa ngokwenene njengento yokucoca.Ikwabonise ukukwazi ukuphelisa amasuntswana asimahla anokuthi angcolise imithombo yamanzi.
I-hypopyroxene ibonisa amandla okubulala iintsholongwane kunye nokucoca amanzi kwiibhaktheriya, i-spores, i-microorganisms elula kunye ne-algae eluhlaza okwesibhakabhaka.Ngenxa yeempawu zayo eziphezulu ze-catalytic kunye nokunciphisa, i-magnesia ihlala isetyenziswa njenge-adsorbent yokucoca amanzi amdaka.
(a) Ukwandiswa kwe-X13500 kunye (b) no-X35000 wokwandisa umfanekiso weTEM wesampulu ye-hypophyllite ehlakaziweyo.(c) I-Raman spectrum ye-hypophyllite ephathwayo kunye (d) ne-XPS spectrum ye-carbon line kwi-hypophyllite spectrum
Ukukhutshwa kwegraphene
Ukulungiselela amatye okutsalwa kwegraphene, aba babini basebenzise imakroskopu ye-electron yokuskena (SEM) ukujonga ubumdaka bentsimbi enzima kunye neporosity kwiisampulu.Baphinde basebenzise ezinye iindlela zebhubhoratri ukujonga ukubunjwa kwesakhiwo ngokubanzi kunye nobukho bezinye iiminerali kwi-hypomphibole.
Emva kokuba uhlalutyo lwesampula kunye nokulungiswa kugqitywe, abaphandi bakwazi ukukhupha i-graphene kwi-diorite emva kokucubungula ngomatshini isampuli evela kuKarelia usebenzisa i-digital ultrasonic cleaner.
Ekubeni inani elikhulu leesampuli linokucutshungulwa kusetyenziswa le ndlela, akukho mngcipheko wokungcoliswa kwesibini, kwaye iindlela zokucubungula isampula ezilandelayo azifunwa.
Kuba iipropathi ezingaqhelekanga zegraphene zaziwa ngokubanzi kuluntu olubanzi lophando lwezenzululwazi, uninzi lweendlela zokuvelisa kunye nokudibanisa ziye zaphuhliswa.Nangona kunjalo, ezininzi zezi ndlela ziinkqubo zamanyathelo amaninzi okanye zifuna ukusetyenziswa kweekhemikhali kunye ne-oxidizing eqinile kunye ne-agent yokunciphisa.
Nangona igraphene kunye nezinye iifilimu zekhabhoni zibonise amandla amakhulu okusebenza kwaye zizuze impumelelo yeR&D, iinkqubo ezisebenzisa ezi mathiriyeli zisephantsi kophuhliso.Inxalenye yomceli mngeni kukwenza ukukhutshwa kwegraphene kube yindleko esebenzayo, okuthetha ukuba ukufumana itekhnoloji efanelekileyo yokusasazwa ngundoqo.
Le ndlela yokusasazwa okanye yokudibanisa iyasebenza kwaye ayinabuhlobo nokusingqongileyo, kwaye amandla obu bugcisa nawo anokubangela iziphene kwigraphene eveliswayo, ngokwenjenjalo kuncitshiswe umgangatho obalaseleyo olindelekileyo wegraphene.
Ukusetyenziswa kwabacoci be-ultrasonic kwi-graphene synthesis kuphelisa iingozi kunye neendleko ezinxulumene neendlela ezininzi kunye neendlela zamachiza.Ukusebenzisa le ndlela kwi-hypophyllite yeminerali yendalo kwavula indlela yendlela entsha yokusingqongileyo yokuvelisa igraphene.
