Nanoparticles yuav yog txaus ntshai peb lub laj thawj tseem ceeb: Nanoparticles tuaj yeem ua rau lub ntsws puas. Peb paub tias 'ultra fine' particles los ntawm cov cav tov diesel, fais fab nroj tsuag thiab incinerators yuav ua rau muaj kev puas tsuaj rau tib neeg lub ntsws. Nanoparticles tuaj yeem nkag mus rau hauv lub cev los ntawm daim tawv nqaij, ntsws thiab digestive system.
Ntxiv mus, nanotechnology puas muaj kev nyab xeeb rau tib neeg?
“Kev taw qhia ib leeg tsis txaus los suav txog qhov kev pheej hmoo tshiab ntawm nanotechnology . FDA yuav tsum tau tshaj tawm cov cai. Raws li Center for Food Kev nyab xeeb , nanoparticles hauv cov zaub mov lossis ntim khoom noj tuaj yeem nkag mus rau hauv tib neeg lub cev los ntawm kev noj, nqus tau los yog tawv nqaij.
nanotechnology hauv kev noj qab haus huv yog dab tsi? Nanotechnology yog kev tshawb fawb ntawm cov ntaub ntawv ntawm theorecular lossis subatomic qib. Txawm li cas los xij, cov teb chaws txom nyem muaj lub luag haujlwm tsis tu ncua los ntxiv dag zog kev kho mob systems thiab muab kev nkag mus rau cov tshuaj dav dav, nanotechnology tuaj yeem, nyob rau lub sijhawm ntev, cawm txoj sia los ntawm kev kuaj mob thiab kev kho mob kom zoo dua.
Yog li ntawd, dab tsi yog qhov tsis zoo ntawm nanotechnology?
Muaj peev xwm qhov tsis zoo suav nrog kev cuam tshuam kev lag luam thiab kev hem thawj rau kev nyab xeeb, kev ceev ntiag tug, kev noj qab haus huv thiab ib puag ncig. Electronics thiab Computing: teb ntawm electronics yog teem rau revolutionized los ntawm nanotechnology.
Cov nyiaj nanoparticles puas tsim kev puas tsuaj rau tib neeg?
Nanosilver tuaj yeem ua rau qhov muag me me thiab tawv nqaij khaus. Nws tuaj yeem ua raws li cov tawv nqaij ua xua. Inhalation ntawm silvernanoparticles feem ntau cuam tshuam rau lub ntsws thiab daim siab. Nws tau raug pom tias nyiaj nanoparticles tej zaum yuav yog genotoxic tomammalian hlwb.

Puas muaj zog npaum li cas yog cov kua qaub los yog cov hauv paus daws teeb meem?
Qhov ntau ntawm 0 mus rau 14 muab kev ntsuas ntawm kev sib piv lub zog ntawm cov kua qaub thiab cov hauv paus daws teeb meem. Cov dej ntshiab thiab lwm cov kev daws teeb meem nruab nrab muaj tus nqi pH ntawm 7. Tus nqi pH tsawg dua 7 qhia tias cov kua qaub yog acidic, thiab pH tus nqi ntau dua 7 qhia tias cov tshuaj yog qhov yooj yim
Cov roj teeb puas muaj teeb meem?
Cov roj teeb hlawv tawm cov pa phem, uas ua rau lub ntsws ua pa. Cov roj teeb tawm: Tsis txhob cuam tshuam cov hluav taws xob xau, nws tuaj yeem ua rau mob hnyav thiab / lossis puas tsuaj rau daim tawv nqaij, mucous membrane lossis ob lub qhov muag
Puas yog kev daws teeb meem yog tshuaj lom neeg?
Raws li UPAC 'kev daws teeb meem yog ib qho kev sib cuam tshuam ntawm cov kuab tshuaj nrog cov kuab tshuaj, uas ua rau kom muaj kev ruaj khov ntawm cov hom solute hauv cov tshuaj.' Hauv cov ntsiab lus, kev daws teeb meem tsis yog tshuaj lom neeg cov tshuaj tiv thaiv, thiab txuas ntxiv qhov kev sib cais ntawm cov ntsev tsis yog tshuaj lom neeg, tab sis kev hloov theem
Dab tsi yog qhov teeb meem ntawm lub teeb nyob rau hauv lub ntuj hmo ntuj hu ua?
Gegenschein, tseem hu ua Counterglow, oval thaj ntawm faint luminosity raws nraim rau lub hnub nyob rau hauv lub hmo ntuj. Lub thaj ntawm lub teeb yog li faint nws tuaj yeem pom tsuas yog thaum tsis muaj lub hli, nyob deb ntawm lub nroog teeb, thiab nrog lub qhov muag yoog rau qhov tsaus ntuj
Puas yog khoov ntawm lub teeb tsis nyob ib puag ncig cov teeb meem?
Diffraction yog pom ntawm lub teeb tsis muaj zog tab sis tsuas yog thaum nthwv dej ntsib teeb meem nrog cov wavelengths me me (xws li cov khoom raug tshem tawm hauv peb cov huab cua). Diffraction yog qhov khoov ntawm nthwv dej ncig obstacles thiab qhib. Tus nqi ntawm diffraction nce nrog nce wavelength
