Daim ntawv thov

Neutron ntes thiab hluav taws xob shielding: Gadolinium yog paub rau nws cov neutron loj cand sib tshooj, uas ua rau gadolinium bromide heev muaj txiaj ntsig zoo heev hauv kev siv nuclear. Nws yog siv nyob rau hauv hluav taws xob shielding cov ntaub ntawv thiab neuon detectors, pab tiv thaiv cov cuab yeej rhiab thiab cov neeg ua haujlwm ntawm kev phom sij. Daim ntawv thov no yog qhov tseem ceeb hauv cov khoom siv hluav taws xob nuclear thiab cov chaw tshawb fawb.
Phosphors hauv teeb pom kev zoo thiab qhia tawm: Gadolinium bromide tuaj yeem siv los ua cov khoom siv phosphor hauv ntau cov kev siv teeb pom kev zoo. Thaum doped nrog lwm yam tsis tshua muaj lub ntiaj teb tsis tshua muaj, nws tuaj yeem txhim kho lub yoj tes, yog li txhim kho cov xim zoo thiab ua haujlwm ntawm lub fluorescent teeb thiab LED qhia. Cov cuab yeej no ua rau nws muaj txiaj ntsig zoo hauv kev txhim kho cov tshuab tsim hluav taws xob siab heev thiab cov tshuab saib.
Sib nqus resonance cov duab (MRI): Gadolinium cov tebchaw (suav nrog Gadolinium bromide) tau siv hauv kev kho mob kev kho mob, tshwj xeeb tshaj yog cov neeg ua kom sib luag rau mri. Gadolinium txhim kho qhov sib piv ntawm cov duab, tso cai pom zoo ntawm cov qauv sab hauv thiab kev txawv txav. Daim ntawv thov no yog qhov tseem ceeb rau kev kuaj mob thiab kev kho mob kho mob hauv kev kho mob xyaum.
Kev Tshawb Nrhiav thiab Kev Loj Hlob: Gadolinium bromide yog siv nyob rau hauv ntau cov ntawv thov kev tshawb fawb, tshwj xeeb hauv cov ntaub ntawv kev tshawb fawb thiab lub luag haujlwm-hauv lub xeev. Nws cov khoom tshwj xeeb ua rau nws lub ntsiab lus kub rau kev txhim kho cov ntaub ntawv tshiab, suav nrog cov khoom sib nqus thiab cov khoom sib nqus thiab cov superconductors. Cov kws tshawb nrhiav tshawb xyuas lub peev xwm ntawm Gadolinium bromide hauv cov ntawv thov tshiab, ua rau nce qib hauv thev naus laus zis thiab cov khoom siv science.
