Electron microscopy - qalab nanotechnology

Electron microscopy waa isku darka habab electron-baaritaankoodu si ay u baaraan microstructure ee adkaha ah, iyo sidoo kale ay ka kooban oo beerta cqaadir deegaanka.

Haddii habkan of baaritaan loo isticmaalo alaabtii gaar ah - microscopes, kaas oo image waxaa kordhay joogitaanka alwaaxdii saqafka haysay electron.

Electron microscopy waxay leedahay laba qeybood oo waaweyn:

• Gudbinta - oo macneheedu yahay microscope electron transmissive taas oo translucent walxaha by dogob electron ah isagoo tamarta ah 50 ilaa 200 keV. The electrons in dhex mari shayga hoos waxbarasho, u hesho on lenses magnetic gaar ah. lenses Kuwaas waxaa la aasaasay on shaashad gaar ah ama image film sawir oo ka mid ah qaab-dhismeedka gudaha ee shayga. Waa inaan sheegaa in microscopy electron gudbinta waxay fursad si aad u hesho koror ku dhowaad 1.5 jeer * 106. Waxay bixisaa fursad lagu xukumo sidaas darteed qaab-dhismeedka crystalline waxyaabaha waxaa loo arkaa habka aasaasiga ah ee waxbarashada dhismeedka ultrathin ee adkaha ah ee kala duwan.

• Scanning (iskaanka) microscopy electron - waxaa lagu fuliyaa iyadoo adeegsanayo microscopes gaar ah, kaas oo ku jirase aad electron adigoo isticmaalaya lenses magnetic ah ayaa la ururinayaa in baaritaan khafiif ah. Waxa uu baaritaanku dusha sare ee shayga, kuna waari dhexdeeda shucaaca sare dhacdaa, oo la ogaado by qalabka kala duwan iyo beddelay calaamadaha u dhigma.

Waa in la ogaadaa in microscope electron uu leeyahay tiro ka mid ah faa'iidooyinka badan hababka dhaqanka ee microanalysis X-ray. Taasi waa sababta ay ayaa noqonaya mid aad caadi ah oo loogu yeeri karaa guul weyn oo nanotechnology casriga ah.

Intaa waxaa dheer, microscopy electron ka dhigaysa horumarinta degdegga ah ee morphometry computer, nuxurka taas oo ah isticmaalka technology computer falanqeeyo ka sii qoto dheer oo buuxda oo ku images electronic.

Si aad u taariikhda, horumariyo a nidaamyada hardware-software, taas oo ay awoodaan in ay ku kaydiso sanamyadooda iyo fuliyaan ay howshu tahay tirakoobka, qabsato ka duwan iyo dhalaalka, dooro qaybaha shaqsi baaritaan microstructures.

microscopes electron casriga ah waxaa lagu qalabeeyay Processor gaar ah in la yareeyo suurtagalnimada burburka si ay u tijaabiso baarka wax, iyo sidoo kale kordhin saxnimada macluumaadka ku saabsan falanqaynta ee microstructure ee alaabta, taas oo si weyn u fududeeyaa shaqada cilmi.

guulaha microanalysis electron waxaa aad loogu isticmaalaa for fahamka isdhexgalka nuclear, taasoo kuu ogolaanayaa inaad si ay u abuuraan wax la guryaha novel, iyo horusocod Qaabaynta saddex geesood ah oo u ogolaanaya in ay baaritaan ku bayoolajiga ah hababka kelli muhiim ah in xambaarsan oo dhan bayoolajiga. Intaa waxaa dheer, iyadoo la adeegsanayo microscopy electron, waxaa suurtagal ah si ay u fuliyaan qaar ka mid ah oo firfircoon tijaabo iyo hesho sal lagama maarmaanka u ah design ee nanostructures cusub.
