Nanometer alumina poda, inozivikanwawo se nano-alumina, chinhu chekucheka-chete chave kushandura ndima yesainzi yemidziyo. Nezvimiro zvayo zvakasiyana uye huwandu hwemashandisirwo, chinhu chidiki ichi asi chine simba chiri kuita hukuru mumaindasitiri akasiyana.
Imwe yeakakosha maitiro e nanometer alumina poda inoshamisa diki diki saizi, kazhinji muhuwandu hwe1-100 nanometers. Iyi ultrafine saizi inoipa yakakwira pamusoro penzvimbo uye yakasarudzika reactivity, zvichiita kuti ive yakakodzera mumiriri kune akawanda epamberi maapplication.
Mumunda weceramics, nanometer alumina poda inoshandiswa kuwedzera michina uye yekupisa zvimiro zvemidziyo. Nekubatanidza nano-aluminium mumatrices eceramic, izvo zvinokonzeresa zvinosanganisirwa zvinoratidza kusimba kwesimba, kusimba, uye kupfeka kuramba. Izvi zvakakonzera kugadzirwa kwepamusoro-kuita zveceramic zvikamu zvekushandisa mukuda maindasitiri uye mainjiniya maapplication.
Uyezve, nanometer alumina poda inoshandiswawo mukugadzira epamberi catalysts. Nzvimbo yayo yepamusoro yepamusoro uye reactivity inoita kuti ive yakanakisa tsigiro yezvinhu zvecatalytic masisitimu, ichigonesa kukwidziridzwa kwekuita uye kugona mumakemikari maitiro akadai sehydrogenation, oxidation, uye hydrocracking.
Munzvimbo yemagetsi uye optoelectronics, nano-alumina inoita basa rakakosha mukugadzirwa kwepamusoro-kuita insulating zvinhu uye substrates. Iyo yakasarudzika dielectric zvivakwa uye kugadzikana kwekupisa kunoita kuti ive chinhu chakakosha mukugadzirwa kwemidziyo yemagetsi, capacitors, uye maseketi akabatanidzwa.
Zvakare, iyo biomedical munda yakabatsirwawo kubva kune yakasarudzika zvivakwa zve nanometer alumina poda. Inoshandiswa mukuvandudza zvinhu zvebioactive, masisitimu ekuendesa zvinodhaka, uye masisitimu einjiniya scaffolds nekuda kweiyo biocompatibility uye bioactivity. Izvi zvikumbiro zvine vimbiso huru yekufambira mberi mukurapa kwekurapa uye mushonga wekuvandudza.
Iko kushandiswa kwakasiyana-siyana kwe nanometer alumina poda inotambanukira kune iyo nzvimbo yekugadzirisa kwezvakatipoteredza zvakare. Nzvimbo yaro yepamusoro yepamusoro uye adsorption kugona inoita kuti ive chinhu chinoshanda chekubvisa zvinosvibisa uye zvinosvibisa kubva mumhepo nemvura, zvichibatsira mukuyedza kuchengetedza kwezvakatipoteredza uye kutonga kusvibiswa.
Sezvinoita chero chinhu chepamberi, kugadzirwa uye kubata nanometer alumina poda inoda kutarisisa kuchengetedzeka uye kufunga kwezvakatipoteredza. Kungwarira kwakakodzera uye mapuroteni anofanirwa kuteverwa kuve nechokwadi chekushandiswa kwakachengeteka uye kuraswa kwechinhu ichi, zvinoenderana neakanakisa maitiro emananomaterials.
Mukupedzisa, nanometer alumina poda inoshandura-mutambo mune zvesainzi, inopa huwandu hwakawanda hwekushandisa uye mabhenefiti mumaindasitiri akasiyana. Hunhu hwayo hwakasiyana uye kuita kwakasarudzika kunoita kuti ive chinhu chakakosha mukugadzirwa kwezvinhu zvepamberi uye matekinoroji. Sezvo tsvakiridzo nekuvandudza mune nanotechnology zvichiramba zvichifambira mberi, mukana we nanometer alumina poda yekufambisa kufambira mberi mune zvesainzi inonakidza.
