Mkpụrụ ndụ ihe nketa nke Cerium Oxide Biphasic: Njikọta Ngwa Abụọ
Mmepe ọhụrụ na nanotechnology ewebatala oge ọhụrụ nke ihe nwere ihe pụrụ iche, ọkachasị n'ihe gbasara nchekwa ike na ngwaọrụ eletrọniki. Otu ihe ọhụrụ dị egwu dị otú ahụ bụ mmepe nke biphasic.ihe ndị na-eme ka ihe dị na cerium oxide dị na ya, nke apụtala dị ka ihe nwere ike ịrụ ọrụ abụọ na ngwa dielectric na supercapacitor. Ihe ọhụrụ a, nke Prakash et al. nyochachara, na-ekpughe nnukwu ikike nke cerium oxide nanoparticles ịgbanwe teknụzụ dị ugbu a, na-enye nkwalite ndị nwere ike ịba uru nke ukwuu ma ngwa ụlọ ọrụ mmepụta ihe na nke ndị ahịa.
Cerium oxide, ihe dị iche iche a maara maka ikike nchekwa oxygen ya na àgwà redox ya, adọtala uche n'ọtụtụ ngalaba. Nanoparticles ya, n'ihi oke elu ha na oke olu ha, na-egosipụta ihe ndị ka mma nke dị oke mkpa maka ngwa dị elu. Nnyocha nke Prakash na ndị ọrụ ibe ya mere na-egosi ọ bụghị naanị na nhazi na ọrụ nke nanoparticles ndị a kamakwa ikike ha nwere ịrụ ọrụ abụọ nke nwere ike ịkwado ọtụtụ ojiji. Ọrụ mmekọrịta a na-etinyeserium oxideihe ndị nanoparticles dị n'ihu n'ihe ọhụrụ e mere iji gboo mkpa na-arịwanye elu maka ngwọta ike dị irè.
Ọmụmụ ihe a kọwara nke ọma usoro mmepụta ihe e ji emepụta nanoparticles cerium oxide biphasic. Ndị nchọpụta ahụ jiri usoro hydrothermal mee ihe maka usoro mmepụta ihe, nke na-enye ohere maka njikwa ziri ezi na nha na ọdịdị nke ihe ndị ahụ. Site n'ịgbanwe paramita njikọta dị iche iche, ha nwetara nanoparticles nke na-egosipụta ma nhazi fluorite na monoclinic. Njikọta pụrụ iche nke usoro a dị oke mkpa ebe ọ na-eme ka ihe eletrọniki dị mkpa maka arụmọrụ kacha mma na sistemụ nchekwa ike dịkwuo mma.
E jiri usoro njirimara dịka X-ray diffraction (XRD) na transmission electron microscopy (TEM) mee ihe nke ọma iji nyochaa nanoparticles emepụtara. Nsonaazụ XRD kwadoro ọnụnọ nke usoro kristal abụọ ahụ, ebe TEM visualization nyere onyonyo doro anya na-egosi otu na njikwa nha nke nanoparticles. Usoro ndị a abụghị naanị na ha na-akwado usoro njikọta kamakwa ha na-egosi njirimara ndị na-ekwe nkwa nke ihe ahụ nke nwere ike ibute nnukwu mmụba na njupụta ike na njikwa.
Otu n'ime ihe ndị na-adọrọ mmasị nke biphasic cerium oxide nanoparticles bụ ihe onwunwe dielectric ha. Dielectrics na-arụ ọrụ dị oke mkpa na ngwaọrụ eletrọniki, na-emetụta ikike arụmọrụ ha, gụnyere nchekwa ike na nnyefe mgbaàmà. Ọdịdị biphasic nke cerium oxide na-eme ka uru dielectric na-agbanwe agbanwe na mfu dị mma, na-eme ka ha dabara nke ọma maka ngwa dị iche iche na capacitors na ihe ndị ọzọ eletrọniki. Mmezi a dị mkpa maka ngwaọrụ ọgbọ na-abịa nke chọrọ arụmọrụ ka elu na obere ihe.
Ọzọkwa, ọmụmụ ihe a na-enyocha ojiji nke nanoparticles cerium oxide nke supercapacitor. A maara Supercapacitors maka ikike ha nwere inye ike ngwa ngwa, ọkachasị na ngwa ndị chọrọ chajị ngwa ngwa na usoro mwepụta. Ntinye nke nanoparticles biphasic cerium oxide na imewe supercapacitor egosila nsonaazụ dị mma, na-eme ka uru capacitance dịkwuo mma ma na-ejigide nkwụsi ike okirikiri dị mma. Akụkụ a na-eme ka ha bụrụ ndị a ma ama maka ngwọta nchekwa ike na ụgbọ ala eletrik na sistemụ ike mmeghari ohuru.
Akụkụ na-adọrọ mmasị nke nnyocha ahụ metụtara nkwado gburugburu ebe obibi nke metụtara iji nanoparticles cerium oxide. Ka ụlọ ọrụ mmepụta ihe na-emesikwu ike na ihe ndị dị mma maka gburugburu ebe obibi, njikọta na itinye cerium oxide na-adabakwa na ụkpụrụ kemịkalụ akwụkwọ ndụ akwụkwọ ndụ. Ntinye ihe ndị dị mfe, ndị na-adịghị egbu egbu nwere ike ibute ngwaahịa dị nchebe ma belata akara ukwu gburugburu ebe obibi nke a na-ejikarị teknụzụ capacitor ọdịnala eme ihe.
Ihe Prakash na ndị otu ya chọpụtara na-enye aka nke ukwuu n'akwụkwọ ndị dị ugbu a, na-enye nghọta zuru oke banyere otu biphasic cerium oxide nanoparticles si arụ ọrụ. Site n'ịkọwapụta usoro ha na ojiji ha nwere ike iji site na usoro nnwale siri ike, nnyocha ahụ na-akwadebe ntọala maka ọmụmụ ihe n'ọdịnihu. Ọrụ ntọala dị otú ahụ dị mkpa maka ndị nchọpụta na ndị injinia ụlọ ọrụ mmepụta ihe bụ ndị na-achọ imepụta ihe ọhụrụ n'ọhịa nke nchekwa ike na ngwaọrụ eletrọniki.
N'ime teknụzụ na-agbanwe agbanwe mgbe niile, ikike ịhazi ihe na nanoscale na-enye nnukwu ohere maka imepụta ihe ọhụrụ. Nanoparticles cerium oxide biphasic nke ekpughere na nyocha a bụ ihe akaebe nke otu nanotechnology nwere ike isi mee ka ihe ndị a pụta ìhè. Site na nyocha na mmepe na-aga n'ihu, anyị nwere ike ịhụ ka a na-etinye ihe ndị a na ngwaahịa kwa ụbọchị, na-eme ka ọrụ ha na nha arụmọrụ ha ka mma.
