Nanoparticles tau siv ntau dua hauv kev tshawb fawb thiab kev lag luam vim lawv cov khoom muaj txiaj ntsig zoo dua piv rau cov khoom siv ntau.Nanoparticles yog ua los ntawm ultrafine particles tsawg dua 100 nm inch.Qhov no yog ib qho me ntsis tus nqi, tab sis raug xaiv vim hais tias nyob rau hauv qhov loj no ntau yam thawj cov cim qhia ntawm "dog teebmeem" thiab lwm yam txawv txawv khoom pom nyob rau hauv nanoparticles muaj feem xyuam rau cov ntaub ntawv loj, vim hais tias cov khoom muaj feem cuam tshuam ncaj qha. nanoparticles, ib tug loj tus naj npawb ntawm cov atoms raug rau saum npoo.Nws tau pom tias cov khoom thiab tus cwj pwm ntawm cov ntaub ntawv hloov dramatically thaum tsim los ntawm nanoscale.Qee yam piv txwv ntawm kev txhim kho uas tshwm sim thaum muaj zog hardness thiab lub zog, hluav taws xob thiab thermal conductivity yog compounded los ntawm nanoparticles.
Kab lus no tham txog cov khoom thiab kev siv ntawm alumina nanoparticles.Aluminium yog P pawg 3rd lub sijhawm, thaum oxygen yog P pawg 2nd lub sijhawm.
Cov duab ntawm alumina nanoparticles yog spherical thiab dawb hmoov.Alumina nanoparticles (kua thiab cov ntaub ntawv khoom) raug cais raws li cov nplaim taws heev thiab khaus, ua rau mob qhov muag thiab ua pa hnyav.
Alumina nanoparticletuaj yeem ua ke los ntawm ntau cov txheej txheem, suav nrog pob milling, sol-gel, pyrolysis, sputtering, hydrothermal, thiab laser ablation.Laser ablation yog ib qho txheej txheem los tsim cov nanoparticles vim tias nws tuaj yeem ua ke hauv cov pa roj, nqus tsev lossis kua. Tsis ntev los no, chemists ntawm Max-Planck-Institut für Kohlenforschung hauv Mülheim an der Ruhr tau tshawb pom ib txoj hauv kev tsim cov corundum, tseem hu ua alpha-alumina, nyob rau hauv daim ntawv ntawm nanoparticles siv ib qho yooj yim mechanical milla millian.
Nyob rau hauv cov ntaub ntawv uas alumina nanoparticles yog siv nyob rau hauv cov kua daim ntawv, xws li aqueous dispersions, lub ntsiab daim ntaub ntawv yog raws li nram no:
• Txhim kho qhov ntom ntom, smoothness, tawg toughness, creep kuj, thermal qaug zog tsis kam thiab puas kuj ntawm polymer khoom ntawm ceramics
Cov kev xav tau nthuav tawm ntawm no yog cov neeg sau thiab tsis tas yuav cuam tshuam cov kev xav thiab kev xav ntawm AZoNano.com.
AZoNano tau tham nrog Dr. Gatti, tus thawj coj hauv kev lag luam nanotoxicology, hais txog ib txoj kev tshawb fawb tshiab uas nws tau koom nrog hauv kev tshuaj xyuas qhov muaj peev xwm txuas ntawm nanoparticle exposure thiab sudden infant death syndrome.
AZoNano tham nrog tus xibfwb Kenneth Burch ntawm Boston College.Burch Group tau tshawb fawb txog kev siv dej khib nyiab raws li kev kis kab mob (WBE) li cas thiaj li tau txais cov ntaub ntawv ntawm lub sijhawm tiag tiag ntawm kev noj tshuaj txhaum cai.
Peb tau tham nrog Dr Wenqing Liu, Tus Nyeem Ntawv thiab Tus Thawj Coj ntawm Nanoelectronics thiab Cov Khoom Siv ntawm Royal Holloway University, London, rau International Women's Day.
Hiden's XBS (Cross Beam Source) system tso cai rau ntau qhov kev saib xyuas hauv MBE deposition applications.Nws yog siv nyob rau hauv molecular beam mass spectrometry thiab tso cai rau nyob rau hauv situ saib xyuas ntawm ntau qhov chaw raws li zoo raws li lub sij hawm lub teeb liab tso zis rau meej tswj ntawm deposition.
Kawm txog Thermo Scientific ™ Nicolet™ RaptIR FTIR microscope tsim los sai sai nrhiav thiab txheeb xyuas cov ntaub ntawv kab, suav nrog, impurities thiab particulates thiab lawv faib hauv cov qauv.
