Nanotechnology vs Molecular Nanotechnology (MNT)
Nanotechnology tsom rau qhov teeb meem ntawm nanometer nplai thiab molecular nanotechnology yog ib pawg ntawm nanotechnology. Yog tias ib qho kev tshawb fawb cuam tshuam nrog cov khoom tsawg dua puas nanometers (nanometer yog ib billionth ntawm ib meter), nws yog nanotechnology. Cov haujlwm no yog ntau qhov kev qhuab qhia uas muaj kev paub txog ntau yam xws li physics, chemistry, engineering thiab biology yog kev koom ua ke.
Nanotechnology Ntau
Nanotechnology yog engineering cov khoom nano-scale ntawm qib molecular siv cov txheej txheem sib txawv. Nanotechnology yog txhua yam hais txog cov tswv yim thiab cov cuab yeej los ua ke nrog nano-scale tsim lossis cov txheej txheem uas siv cov khoom ntawm qib molecular kom raug thiab ua haujlwm tau zoo.
Siv kev paub txog kev coj tus cwj pwm ntawm nano-scale, nanotechnology exploits lub zog xws li lub zog, lightness, hluav taws xob thiab thermal conductance thiab reactivity los tsim thiab tsim cov khoom muaj txiaj ntsig. Muaj ob txoj hauv kev hauv nanotechnology hu ua top-down mus kom ze thiab hauv qab-up mus kom ze.
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 thoob plaws ntiaj teb tau nqis peev ntau rau kev tshawb fawb nanotechnology.
Molecular nanotechnology (MNT)
Molecular nanotechnology yog ib pawg ntawm nanotechnology, uas tsom mus rau kev tsim cov qauv molecular nyiam nyob rau hauv qab-up mus kom ze los ntawm kev coj cwj pwm (lossis mechanosynthesis). Ntau lub tswv yim xws li kev sib dhos tus kheej, kev tsim khoom molecular, thiab nano robotics koom rau hauv pawg no.
Lub tswv yim pib ntawm kev sib dhos molecular tau muab los ntawm Richard Feynman, thiab Eric Drexler tau tsim lub tswv yim los ntawm ntau lub tswv yim tshiab ntawm cov tshuab molecular. Muaj ntau yam piv txwv rau cov tshuab molecular hauv qhov thiab MNT sim ua qhov no. Txawm tias tib neeg yog tus kheej sib sau ua ke ntawm cov hlwb thiab DNA thiab cov protein molecules.
Dab tsi yog qhov txawv ntawm ?
¤ Nanotechnology yog txhua yam hais txog engineering, kev tswj hwm lossis kev tsim khoom ntawm qhov ntsuas tsawg dua 100nm, thiab molecular nanotechnology yog ib pawg ntawm nanotechnology.
¤ Txawm hais tias, nanotechnology siv ob qho tib si saum-down thiab hauv qab-up, MNT tsuas yog tsom mus rau hauv qab-up.
