I-electron microscopy iyithuluzi le-nanotechnology

I-electron microscopy iyinhlanganisela yezindlela ze-electron-probe ezenza kube lula ukuphenya i-microstructure yezinsimbi eziqinile, kanye nokwakhiwa kwawo kwendawo kanye ne-microfield.

Ngalolu hlelo locwaningo, amadivaysi akhethekile asetshenziselwa - ama-microscopes, lapho isithombe sikhuliswa khona ngenxa yobukhona bezinsika ze-electron.

I-electron microscopy inezinkomba ezimbili eziyinhloko:

• Ukuguquguquka - kwenziwa nge-electron microscopes, lapho izinto zikhanyiswa khona nge-electrioni ene-energy engu-50 kuya ku-200 keV. Amakhemikhali adlulisa into ephenywe yilezi zenzeke ezilwaneni ezikhethekile zamagesi. Lawa ma-lens afaka esikrinini esikhethekile noma ifilimu isithombe sezakhiwo zangaphakathi zento. Kumele kuthiwa ukuhamba kwe-electron microscopy kwenza kube lula ukukhushulwa izikhathi ezingaba ngu-1.5 * izikhathi ezingu-106. Kwenza kube lula ukwahlulela isakhiwo se-crystalline yezinto, ngakho-ke kubhekwa njengendlela eyinhloko yokutadisha izakhiwo ze-ultrathin ezinamandla ezihlukahlukene.

• Ukuskena (ukuskena) i-electron microscopy - kwenziwa nge-microscopes ekhethekile lapho i-electron beam ne-use lens magnetic ihlangene ngayo iplanethi encane. Ihlola ubuso bezinto eziphenywayo, ngokubonakala kwe-radiation yesibili, etholakala yizimboni ezihlukahlukene futhi iguqulwa ibe yizibonakaliso ezihambisanayo zevidiyo.

Kumele uqaphele ukuthi i-electron microscopy inezinzuzo eziningana ngezindlela zokuhlaziya zendabuko ye-X-ray. Yingakho isanda kakhulu futhi ingabizwa ngokuthi yimpumelelo ebalulekile ye-nanotechnology yanamuhla.

Ngaphezu kwalokho, i-electron microscopy ibangela ukuthuthukiswa okunamandla kwe-computer morphometry, okuyisisekelo sokusebenzisa ubuchwepheshe bekhompuyutha ukuze kusetshenziswe ngokugcwele futhi kuphelele ukuqoshwa kwezithombe zobuchwepheshe.

Kuze kube manje, i-hardware ne-software izinhlelo ezikwazi ukukhumbula ngekhanda izithombe futhi zenze ukucubungula kwazo izibalo, zilungise ukungafani nokukhanya kwazo, zikhomba imininingwane ngayinye yemiphakamiso yokuphenya.

Ama-microscopes anamuhla anamaprosesa akhethekile ayanciphisa amathuba okulimaza amasampula alokho okucutshungulwayo, futhi akhulise ukwethembeka kwedatha ehlobene nokuhlaziywa kwe-microstructure yezinto, okusiza kakhulu umsebenzi wabacwaningi.

Impumelelo ye-microanalysis ye-electronic isetshenziselwa ukuqonda ukusebenzisana kwe-athomu, okuvumela ukudala impahla enezinto ezintsha, futhi ukuthuthukiswa kwezinto ezintathu eziqhubekayo kuvumela ukuthi izazi zezinto eziphilayo zifunde izindlela ezibalulekile ze-molecular ezenza zonke izinqubo eziphilayo. Ngaphezu kwalokho, ngenxa yokusetshenziswa kwe-electron microscopy, kungenzeka ukuba kwenziwe uchungechunge lwezivivinyo ezinamandla futhi uthole isisekelo esidingekayo ekudalweni kwezinto ezintsha.
