Nano vs Micro | Nano vs Micro Technologies
Ob qho tib si micro thiab nano thev naus laus zis yog hais txog kev tsim cov khoom lag luam kom ua tau zoo dua thiab ua haujlwm tau zoo. Ntawm no, cov ntsiab lus micro thiab nano hais txog, me me npaum li cas ntawm kev tswj hwm. Qee cov txheej txheem tsim khoom, uas tau dhau los ua rau micro thev naus laus zis, tam sim no tau nce ntxiv thiab tam sim no lawv nyob hauv thaj tsam ntawm nanotechnology. Cov haujlwm ntawm micro thiab nano technology ntsig txog kev ua haujlwm yog ua tiav hauv cov chav huv huv tshwj xeeb, uas tsis muaj plua plav thiab av. Tsis tas li ntawd, nyob rau hauv ob qho tib si micro thiab nano thev naus laus zis tshawb fawb, cov kws tshawb fawb yuav tsum ua raws li kev hnav khaub ncaws tshwj xeeb los tiv thaiv cov plua plav me me cuam tshuam nrog cov khoom.
YMicro Technology
Micrometer (tseem hu ua micron) yog ib lab ntawm ib lub 'meter' (10 ^-6 m). Micro thev naus laus zis yog siv hauv kev tsim cov tshuab miniaturized lossis cov khoom ntawm micrometer nplai. Lub taub hau lub tshuab luam ntawv, sensors thiab kev sib xyaw ua ke yog cov piv txwv rau cov khoom lag luam micro.
Microelectromechanical System (MEMS) yog ib daim ntawv thov nrov micrometer. MEMS muaj cov khoom siv me me xws li levers, springs thiab kua channel nrog rau cov hluav taws xob circuits yog embedded rau ib tug me me nti. MEMS tam sim no tau hloov kho ntxiv mus rau NEMS (Nanoelectromechanical System).
Nanotechnology Ntau
Nano yog lo lus Greek txhais tau tias 'Dwarf' thiab nanometer yog billionth ntawm ib 'meter' (10^-9m). Nanotechnology yog tsim, tsim lossis tswj ntawm nanometer (ib billionth ntawm ib meter) nplai. Qhov loj ntawm cov khoom lag luam yuav tsum tsawg dua li pua nanometers, tsawg kawg hauv ib qhov ntev, hu rau ib yam dab tsi los ua nanotechnology. Carbon Nanotube Field Effect Transistor (CNTFET) yog ib qho piv txwv rau cov khoom siv nanotechnology.
Nanotechnology tau siv ntau thaj chaw suav nrog IT, tsheb, kev kho mob, textile thiab kev lag luam ua liaj ua teb. Nanotechnology xav tias yuav yog lub kiv puag ncig tom ntej thiab ntau lub tseem fwv, tsev kawm qib siab thiab tuam txhab lag luam thoob plaws hauv kev nqis peev nyiaj ntau ntawm kev tshawb fawb nanotechnology.
Qhov txawv ntawm micro thiab nano technologies
1. Cov khoom lag luam qhov ntsuas hauv nanotechnology yog txhiab npaug me dua microtechnology
2. Nanotechnology yog tshiab dua li micro technology thiab kev tshawb fawb ntau dua tau ua tiav thoob ntiaj teb ntawm nws.
3. Tus nqi ntawm kev tshawb fawb nanotechnology yog siab dua ntawm micro technologies tam sim no.
4. Txawm hais tias, hauv qab-up mus kom ze yog ua raws ob qho tib si micro thiab nano technologies, molecular scale sib dhos tsuas yog muaj nyob rau hauv nanotechnology.
5. Qee cov txheej txheem tsim khoom uas yav dhau los tau koom nrog kev siv tshuab micro, tam sim no tau nce ntxiv, thiab tam sim no lawv tau koom nrog nanotechnology.
6. Cov txiaj ntsig sib txawv hauv microtechnologies tuaj yeem tau txais los ntawm nanotechnology raws li txoj cai ntawm quantum physics ua qhov tseem ceeb ntawm qhov ntsuas qis.
7. Txij li thaum, nam piv (ntoog cheeb tsam / ntim) yog siab dua rau nano hais, cov khoom ntawm nanotechnology muaj ntau reactive tshaj micro technology.
