Ihe ndị dị n'ụwa na-adịghị ahụkebe n'onwe ha bara ụba na usoro eletrọnịkị ma gosipụta ọtụtụ njirimara nke ọkụ, ọkụ eletrik na magnetism. Nano obere ụwa, gosiri ọtụtụ atụmatụ, dị ka obere size mmetụta, elu elu mmetụta, quantum mmetụta, ike ọkụ, eletriki, magnetik Njirimara, superconductivity, Gao Huaxue ọrụ, wdg, nwere ike ukwuu melite arụmọrụ nke ihe onwunwe na ọrụ, ịzụlite. ọtụtụ ihe ọhụrụ. Na ngwa anya, ihe luminescent, ihe kristal, ihe ndọta, ihe batrị, seramiki eletrọnịkị, seramiki injinịa, ihe ndị na-eme ihe na mpaghara teknụzụ ndị ọzọ dị elu, ga-arụ ọrụ dị mkpa.
Nnyocha mmepe na mpaghara ngwa ugbu a.
1. Ihe ndị na-egbuke egbuke nke ụwa: obere ụwa nano-phosphor ntụ ntụ (ụtụ agba, ntụ ntụ oriọna), a ga-eme ka ọrụ ọkụ dị mma, na oriri nke ụwa na-adịghị ahụkebe ga-ebelata nke ukwuu. Na-ejikarị Y2O3, Eu2O3, Tb4O7, CeO2, Gd2O3. Nwa akwukwo ohuru ihe maka onyonyo agba agba di elu.
2. Nano-superconducting ihe: YBCO superconductors kwadebere site Y2O3, pụrụ iche mkpa film ihe, kwụsiri ike ịrụ ọrụ, elu ike, mfe hazie, nso bara uru ogbo, na-ekwe nkwa atụmanya.
3. Obere ụwa nano-magnetic ihe: eji maka magnetik ebe nchekwa, magnetik mmiri mmiri, ibu magnetoresistance, wdg, nke ukwuu mma na arụmọrụ na-eme ka ngwaọrụ ghọọ elu-arụmọrụ miniaturization. Dị ka oxide giant magnetoresistance target (REMnO3, wdg).
4. Igwe ihe eji arụ ọrụ dị elu nke ụwa: jiri superfine ma ọ bụ nanoscale Y2O3, La2O3, Nd2O3, nkwadebe Sm2O3 dị ka seramiki eletrọnịkị (ihe mmetụta elektrọnik, ihe PTC, ngwa ngwa ndakwa nri, ihe ndị na-eme ihe ike, thermistors, wdg), akụrụngwa eletriki, akụrụngwa thermal, nkwụsi ike, emeziwanye ọtụtụ, bụ akụkụ dị mkpa nke ihe eletrọnịkị iji kwalite. Dịka ọmụmaatụ, nanometer Y2O3 na ZrO2 nwere ike na ike siri ike na seramiki dị ala na-ekpo ọkụ, nke a na-eji maka ibu, ịkpụ ngwaọrụ na ngwaọrụ ndị ọzọ na-eguzogide. A na-emeziwanye arụmọrụ nke capacitors multi-layer na ngwa ngwa ndakwa nri na nanometer Nd2O3 na Sm2O3.
5. Nano-catalyst ụwa na-adịghị ahụkebe: n'ọtụtụ mmeghachi omume kemịkalụ, iji ihe ndị na-eme ka ụwa dị ụkọ nwere ike imeziwanye ọrụ catalytic na arụmọrụ catalytic. CeO2 nano ntụ ntụ dị ugbu a nwere uru nke ọrụ dị elu, ọnụ ala dị ala na ogologo ndụ n'ime ihe mkpocha ụgbọ ala, ma jiri ọtụtụ puku tọn dochie ọla ndị kachasị ọnụ ahịa kwa afọ.
6. Rare earth ultraviolet absorber: nanometer CeO2 ntụ ntụ nwere ike absorption nke ultraviolet ụzarị, eji na sunscreen ịchọ mma, sunscreen eriri, ụgbọala iko, wdg.
7. Ịdị ụkọ ụwa nkenke polishing: CeO2 nwere mmetụta polishing dị mma na iko na ihe ndị ọzọ. Nano CeO2 nwere oke polishing nkenke ma ejiri ya mee ihe na ngosipụta kristal mmiri mmiri, otu mgbawa silicon, nchekwa iko, wdg.
Na nkenke, ngwa nke obere ụwa nanomaterials ka amalitela, ma na-elekwasị anya n'ọhịa nke ihe ọhụrụ teknụzụ dị elu, nwere uru dị elu, mpaghara ngwa ngwa, nnukwu ikike na atụmanya azụmahịa na-ekwe nkwa.
