Uphuhliso lwakutshanje kwi-nanotechnology luzise ixesha elitsha lezinto ezineempawu ezikhethekileyo, ngakumbi kwicandelo lokugcina amandla kunye nezixhobo ze-elektroniki. Enye into entsha ephawulekayo kukuphuhliswa kwe-biphasiciiparticles ze-cerium oxide, ezivele njengezinto ezisebenza kabini kwizicelo ze-dielectric kunye ne-supercapacitor. Olu phuhliso, oluphononongwe nguPrakash et al., lubonisa amandla amakhulu e-cerium oxide nanoparticles okuguqula ubuchwepheshe bangoku, zibonelela ngophuculo olunokuba luncedo kakhulu kwizicelo zoshishino kunye nabathengi.
I-Cerium oxide, into eguquguqukayo eyaziwa ngokuba namandla ayo okugcina ioksijini kunye nokuziphatha kwe-redox, ifumene ingqalelo kwiindawo ezahlukeneyo. Ii-nanoparticles zayo, ngenxa yomlinganiselo wazo ophezulu womphezulu ukuya kumthamo, zibonisa iipropati eziphuculweyo ezibalulekileyo kwizicelo eziphambili. Uphando olwenziwe nguPrakash kunye noogxa bakhe lugxininisa kungekuphela nje ukuguquguquka kwesakhiwo nokusebenza kwezi nanoparticles kodwa kunye nobuchule bazo obunendima ezimbini obunokwanelisa uluhlu olubanzi lokusetyenziswa. Olu sebenziso oluhambelanayo lubekai-cerium oxideii-nanoparticles ziphambili kwiindlela ezintsha ezenzelwe ukujongana nemfuno ekhulayo yezisombululo zamandla ezisebenzayo.
Olu phononongo luchaza ngononophelo amaqhinga okwenziwa asetyenziswa ukuvelisa i-biphasic cerium oxide nanoparticles. Abaphandi basebenzise indlela ye-hydrothermal kwinkqubo yokwenza, evumela ulawulo oluchanekileyo kubungakanani be-particle kunye ne-morphology. Ngokulungisa iiparamitha ezahlukeneyo zokwenziwa, bafikelele kwi-nanoparticles ezibonisa zombini izakhiwo ze-fluorite kunye ne-monoclinic. Olu dibaniso lwahlukileyo lwezigaba lubalulekile njengoko luphucula iipropati ze-elektroniki ezifunekayo ekusebenzeni kakuhle kwiinkqubo zokugcina amandla.
Iindlela zokuchonga iimpawu ezifana ne-X-ray diffraction (XRD) kunye ne-transmission electron microscopy (TEM) zisetyenziswe kakhulu ukuhlalutya ii-nanoparticles ezidityanisiweyo. Iziphumo ze-XRD ziqinisekisile ukubakho kwezigaba zombini zekristale, ngelixa ukubona nge-TEM kubonelele ngemifanekiso ecacileyo ebonisa ukufana kwee-nanoparticles kunye nolawulo lobungakanani. Ezi ndlela aziqinisekisi nje kuphela i-synthesis protocol kodwa zikwabonisa iimpawu ezithembisayo zezinto ezinokukhokelela ekuphuculeni okukhulu kuxinano lwamandla kunye nokuqhuba.
Enye yeempawu ezinomtsalane ze-biphasic cerium oxide nanoparticles ziimpawu zazo ze-dielectric. Ii-Dielectrics zidlala indima ebalulekileyo kwizixhobo ze-elektroniki, zichaphazela amandla azo okusebenza, kubandakanya ukugcinwa kwamandla kunye nokudluliselwa kwesignali. Uhlobo lwe-biphasic lwe-cerium oxide lwenza kube lula ukuphucula i-dielectric constant kunye ne-loss tangent values, nto leyo ebenza bafaneleke kakhulu kwizicelo ezahlukeneyo kwi-capacitors nakwezinye izinto ze-elektroniki. Olu phuculo lubalulekile kwizixhobo zesizukulwana esilandelayo ezifuna ukusebenza okuphezulu kunye nezinto ezincinci.
Ngaphezu koko, olu phononongo lujonga ukusetyenziswa kwe-supercapacitor ye-cerium oxide nanoparticles. Ii-Supercapacitors ziyaqatshelwa ngokukwazi kwazo ukuhambisa amandla ngokukhawuleza, ngakumbi kwizicelo ezifuna imijikelo yokutshaja ngokukhawuleza kunye nokukhupha. Ukufakwa kwe-biphasic cerium oxide nanoparticles kuyilo lwe-supercapacitor kubonise iziphumo ezithembisayo, kuphucula amaxabiso e-capacitance ngelixa kugcinwa uzinzo oluhle kakhulu lomjikelo. Olu candelo lubenza babe ngumviwa obalaseleyo wezisombululo zokugcina amandla kwizithuthi zombane kunye neenkqubo zamandla avuselelekayo.
Inxalenye enomdla yophando iphathelele ekuzinzeni kwendalo okunxulumene nokusebenzisa ii-nanoparticles ze-cerium oxide. Njengoko amashishini egxininisa ngakumbi kwizixhobo ezihambelana nokusingqongileyo, ukwenziwa nokusetyenziswa kwe-cerium oxide kuhambelana nemigaqo yekhemistri eluhlaza. Ukufakwa kwezinto ezikhaphukhaphu, ezingenabungozi kunokubangela iimveliso ezikhuselekileyo kwaye kunciphise umngcipheko wendalo odla ngokunxulunyaniswa nobuchwepheshe be-capacitor bendabuko.
Iziphumo zikaPrakash et al. zinegalelo elikhulu kwiincwadi ezikhoyo, zibonelela ngokuqonda okubanzi kwendlela esebenza ngayo i-biphasic cerium oxide nanoparticles. Ngokucacisa iindlela zazo kunye nokusetyenziswa kwazo ngokusebenzisa iiprotokholi zovavanyo ezingqongqo, uphando lulungiselela isiseko sezifundo zexesha elizayo. Umsebenzi osisiseko onjalo ubalulekile kubaphandi kunye neenjineli zoshishino abajonge ukuvelisa izinto ezintsha ngakumbi kwicandelo lokugcina amandla kunye nezixhobo ze-elektroniki.
Kwimeko-bume yetekhnoloji ehlala itshintsha, ukukwazi ukulungisa izinto kwi-nanoscale kunika amathuba amakhulu okuvelisa izinto ezintsha. Ii-nanoparticles ze-biphasic cerium oxide ezityhilwe kolu phando zibubungqina bendlela i-nanotechnology enokukhokelela ngayo kwimpumelelo ebalulekileyo. Ngophando oluqhubekayo nophuhliso, sinokubona ezi zinto zidityaniswa kwiimveliso zemihla ngemihla, ziphucula ukusebenza kwazo kunye nemilinganiselo yokusebenza.
