Kev Piav Qhia & Nta

Piav Qhia: WNX siv cov thev naus laus zis tsim khoom tsis siv neeg thiab siv cov khoom siv raw zoo los tsim cov khoom zooLanthanum Nitrate.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Lanthanum Nitrate tsis muaj cov khoom tsis huv los ntawm cov khoom tsis tshua muaj (xws li hlau, calcium, sodium), thiab cov ntsiab lus tsis huv yog tsawg.

Kev yaj zoo:Lanthanum Nitrate tuaj yeem yaj sai sai hauv dej thiab cov kua qaub muaj zog.

Kev sib xws: Kev tswj hwm cov khoom nruj hauv kev tsim khoomLanthanum Nitrate ua kom ruaj khov zoo rau kev lag luam loj.

Cov tshuaj catalyst rau kev lag luam tshuaj lom neeg: Lanthanum nitrate ua haujlwm ua cov tshuaj catalyst Lewis acid zoo thiab siv dav hauv ntau yam kev hloov pauv organic, xws li acetylation reactions ntawm cov cawv, phenols, thiab amines, nrog rau kev tsim cov acetaldehydes thiab bis (indolyl) methane los ntawm kev sib sau ua ke ntawm aldehydes thiab cawv. Nws tseem yog ib qho tseem ceeb hauv kev npaj cov roj av catalytic cracking (FCC) catalysts, uas pab txhim kho kev ua haujlwm zoo thiab zoo ntawm kev tsim roj.

Tus Neeg Ua Haujlwm Tshem Tawm Phosphorus Zoo: Vim nws cov khoom siv tshuaj lom neeg, lanthanum nitrate tuaj yeem tshem tawm cov phosphate ntawm cov dej los ntawm kev nag, uas pab daws qhov teeb meem ntawm cov dej eutrophication. Cov khoom no kuj tseem ua rau nws siv tau ua tus neeg sawv cev kho pas dej da dej kom tshem tawm cov phosphate uas xav tau rau kev loj hlob ntawm algae.

Kev Ua Liaj Ua Teb thiab Kev Tshawb Fawb Txog Tsob Ntoo: Kev tshawb fawb tau qhia tias qhov muaj lanthanum nitrate nruab nrab tuaj yeem tswj cov vitamin C (Vc) hauv cov txiv hmab txiv ntoo xws li txiv pos nphuab. Qhov no ua tiav los ntawm kev cuam tshuam cov haujlwm ntawm cov enzymes tseem ceeb (xws li GalLDH) hauv biosynthesis, regeneration, thiab degradation pathways. Nws kuj tseem tuaj yeem txo qhov cuam tshuam ntawm alkaline kev ntxhov siab thiab lwm yam kev nyuaj siab ib puag ncig rau kev loj hlob ntawm ryegrass, thiab txhawb kev loj hlob ntawm cov nroj tsuag los ntawm kev txhim kho cov ntsiab lus ntawm cov xim photosynthetic thiab kev ua haujlwm ntawm photosynthetic electron transfer.

Cov khoom siv ua ntej thiab cov tshuaj synthesis intermediates: Lanthanum nitrate yog ib qho tseem ceeb precursor rau kev npaj ntau yam khoom siv ua haujlwm siab heev. Nws yog siv rau hauv kev tsim cov iav kho qhov muag, hmoov fluorescent, cov khoom siv ceramic capacitor (xws li strontium titanate lanthanum), thiab kev npaj lanthanum manganese oxide (LaMnO₃) cov yeeb yaj kiab los ntawm txoj kev sol-gel lossis electrochemical deposition. Tsis tas li ntawd, nws tseem yog ib qho khoom siv raw nruab nrab tseem ceeb rau kev tsim cov lanthanum compounds (xws li lanthanum oxide).
