Qhov sib txawv tseem ceeb ntawm X-ray crystallography thiab X-ray diffraction yog qhov x-ray crystallography yog cov txheej txheem uas ib leeg muaju raug rau x-rays, qhov x-ray diffraction yog cov txheej txheem uas dav. ntau hom ntawm cov khoom siv rau kev ntsuas.
X-ray crystallography thiab x-ray diffraction yog ib qho tseem ceeb analytical cov tswv yim uas peb tuaj yeem siv los txiav txim cov qauv thiab cov khoom ntawm cov ntaub ntawv crystalline.

YX-Ray Crystallography yog dab tsi?
X-ray crystallography tuaj yeem piav qhia raws li kev sim kev tshawb fawb uas txiav txim siab cov qauv atomic thiab molecular ntawm cov siv lead ua. Cov qauv crystalline ntawm cov siv lead ua tuaj yeem ua rau cov nqaj ntawm qhov xwm txheej X-rays ua rau cov nqaj mus rau ntau qhov kev qhia tshwj xeeb.
Ib tus crystallographer tuaj yeem ntsuas lub kaum ntse ntse thiab siv zog ntawm cov kab teeb pom kev sib txawv los tsim cov duab 3D ntawm qhov ntom ntom ntawm cov electrons hauv cov khoom siv lead ua no. Siv cov khoom siv hluav taws xob no, peb tuaj yeem txiav txim siab qhov chaw nruab nrab ntawm cov atoms hauv cov siv lead ua, cov tshuaj sib txuas nrog rau cov teeb meem crystallographic thiab lwm yam ntaub ntawv tseem ceeb.
Daim duab 01: Powder X-ray Diffractometer hauv Kev Ua Haujlwm
X-ray crystallography muaj feem xyuam rau ob peb lwm txoj hauv kev los txiav txim siab cov qauv atomic. Nws tsis yooj yim los tsim cov qauv zoo sib xws los ntawm kev tawg ntawm electrons lossis neutrons.
X-Ray Diffraction yog dab tsi?
X-ray diffraction tuaj yeem piav qhia raws li qhov tshwm sim uas cov atoms ntawm cov siv lead ua ua rau muaj kev cuam tshuam cov qauv ntawm cov nthwv dej ntawm qhov teeb meem ntawm x-rays. Nyob rau hauv txoj kev no, lub dav hlau atomic ntawm cov siv lead ua ua rau ntawm X-ray, tib yam li kev txiav txim siab diffraction grate rau ntawm lub teeb ci.
X-ray diffraction yog cov txheej txheem uas muaj txiaj ntsig zoo hauv cov ntaub ntawv tshawb fawb rau kev txiav txim siab ntawm cov qauv crystallographic ntawm cov khoom. Cov txheej txheem no ua haujlwm los ntawm irradiating ib yam khoom nrog rau qhov xwm txheej x-rays thiab ntsuas qhov kev siv zog, tawg cov ces kaum ntawm x-rays, thiab lwm yam., uas tawm ntawm cov khoom.
Daim duab 02: XRD Diffractometer
Feem ntau, x-ray diffraction yog qhov tseem ceeb hauv cov yam ntxwv ntawm cov khoom siv xws li cov qauv siv lead ua, crystalline loj, lim, thiab lwm yam. Yog li ntawd, kev siv cov txheej txheem no hauv kev tshawb fawb tshuaj yog qhov nce ntxiv.
Peb tuaj yeem qhia qhov x-ray diffraction li XRD. Muaj ntau hom kev x-ray diffraction xws li micro XRD, parallel beam XRD, parallel XRD rau hmoov, protein crystallography, thiab neutron diffraction.
Qhov txawv ntawm X-ray Crystallography thiab X-ray Diffraction yog dab tsi?
X-rays yog ib qho tseem ceeb heev nyob rau hauv ntau yam kev tshuaj ntsuam xyuas xws li x-ray crystallography. Qhov sib txawv tseem ceeb ntawm X-ray crystallography thiab X-ray diffraction yog tias x-ray crystallography yog hais txog cov txheej txheem uas ib leeg muaju raug rau x-rays, thaum x-ray diffraction yog hais txog cov txheej txheem uas muaj ntau hom ntawv. ntawm cov khoom siv rau kev ntsuas. Tsis tas li ntawd, x-ray crystallography yog kev sim kev tshawb fawb, qhov x-ray diffraction yog cov txheej txheem tshuaj.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm X-ray crystallography thiab X-ray diffraction.
Summary – X-ray Crystallography vs X-ray Diffraction
X-ray crystallography yog qhov kev sim kev tshawb fawb uas txiav txim siab lub atomic thiab molecular qauv ntawm ib tug siv lead ua, thaum X-ray diffraction yog ib tug tshwm sim nyob rau hauv uas cov atoms ntawm ib tug siv lead ua ua rau muaj kev cuam tshuam cov qauv ntawm cov nthwv dej nyob rau hauv qhov teeb meem beam. ntawm x-rays. Qhov sib txawv tseem ceeb ntawm X-ray crystallography thiab X-ray diffraction yog tias x-ray crystallography yog hais txog cov txheej txheem uas ib leeg muaju raug rau x-rays, thaum x-ray diffraction yog hais txog cov txheej txheem uas muaj ntau hom ntawv. ntawm cov khoom siv rau kev ntsuas.
