I ka wā o ka mālama ʻana a me ka lawe ʻana, pono e nānā ʻia i ka moisture-proof a pale i ka pōʻino o ka pahu.
Pehea ka ʻokoʻa o ka nano-dysprosium oxide mai ka dysprosium oxide kuʻuna?
Ke hoʻohālikelike ʻia me ka dysprosium oxide kuʻuna, ʻo ka nano-dysprosium oxide he ʻokoʻa koʻikoʻi i ke kino, kemika a me nā waiwai noi, i ʻike nui ʻia i nā ʻano aʻe:
1. Ka nui o ka ʻāpana a me ka ʻili kiko
Nano-dysprosium oxide: Aia ma waena o 1-100 nanometer ka nui o ka pōpō, me ka ʻāpana ili kikoʻī kiʻekiʻe loa (e laʻana, 30m²/g), ka ratio atomic surface kiʻekiʻe, a me ka hana ʻili ikaika.
ʻO ka dysprosium oxide kuʻuna: ʻOi aku ka nui o ka ʻāpana, maʻamau ma ka pae micron, me kahi ʻāpana kikoʻī liʻiliʻi a me ka haʻahaʻa haʻahaʻa.
2. Na waiwai kino
ʻO nā waiwai Optical: Nano-dysprosium oxide: He ʻoi aku ka kiʻekiʻe o ka refractive index a me ka reflectivity, a hōʻike i nā waiwai optical maikaʻi loa. Hiki ke hoʻohana ʻia i nā mea ʻike maka, spectrometers a me nā māla ʻē aʻe.
Dysprosium oxide kuʻuna: Hōʻike nui ʻia nā waiwai optical i kāna kuhikuhi refractive kiʻekiʻe a me ka nalowale haʻahaʻa haʻahaʻa, akā ʻaʻole ia e like me ka nano-dysprosium oxide i nā noi optical.
Nā waiwai mākēneki: Nano-dysprosium oxide: Ma muli o kona kiʻekiʻe kikoʻī kikoʻī kikoʻī a me ka hana o ka ʻili, hōʻike ka nano-dysprosium oxide i ke kiʻekiʻe kiʻekiʻe a me ke koho koho i ka magnetism, a hiki ke hoʻohana ʻia no ka hoʻonā kiʻi kiʻi kiʻi kiʻekiʻe a me ka mālama ʻana.
Kuʻuna dysprosium oxide: loaʻa ka magnetism ikaika, akā, ʻaʻole i like ka nui o ka pane magnetic e like me ka nano dysprosium oxide.
3. Nā waiwai kemika
Reactivity: Nano dysprosium oxide: he kiʻekiʻe kiʻekiʻe kemika reactivity, hiki oi aku ka pono adsorb reactant molekele a hoʻokēʻai i ka chemical reaction rate, no laila e hōʻike ana i ka hana kiʻekiʻe ma ka catalysis a me nā hopena kemika.
Dysprosium oxide kuʻuna: loaʻa ke kūpaʻa kemika kiʻekiʻe a me ka haʻahaʻa haʻahaʻa.
4. Nā wahi noi
Nano dysprosium oxide: Hoʻohana ʻia i nā mea magnetic e like me ka mālama magnetic a me nā mea hoʻokaʻawale magnetic.
Ma ke kahua optical, hiki ke hoʻohana ʻia no nā mea hana kiʻekiʻe e like me nā lasers a me nā sensor.
Ma ke ʻano he mea hoʻohui no nā kiʻekiʻe-hana NdFeB mau magnet.
Kuʻuna dysprosium oxide: Hoʻohana nui ʻia e hoʻomākaukau i ka dysprosium metala, nā mea hoʻohui aniani, nā mea hoʻomanaʻo magneto-optical, etc.
5. Keʻano hoʻomākaukau
Nano dysprosium oxide: hoʻomākaukau pinepine ʻia e ke ʻano solvothermal, alkali solvent method a me nā ʻenehana ʻē aʻe, hiki ke hoʻomalu pono i ka nui o ka particle a me ka morphology.
ʻO ka dysprosium oxide kuʻuna: hoʻomākaukau nui ʻia e nā ʻano kemika (e like me ke ʻano o ka oxidation, ke ʻano o ka ua) a i ʻole ke ʻano kino (e like me ke ʻano evaporation vacuum, ke ʻano sputtering)
