Deuterium yog ib qho isotope ruaj khov ntawm hydrogen. Cov isotope no muaj cov khoom sib txawv me ntsis los ntawm nws cov isotope ntau tshaj plaws (protium), thiab muaj txiaj ntsig hauv ntau txoj kev tshawb fawb, suav nrog nuclear magnetic resonance spectroscopy thiab quantitative mass spectrometry. Nws yog siv los kawm ntau yam, los ntawm kev tshawb fawb ib puag ncig mus rau kev kuaj kab mob.

Kev ua lag luam rau cov tshuaj isotope-labeled ruaj khov tau pom tus nqi nce ntau dua 200% xyoo dhau los. Cov qauv no tshwj xeeb tshaj yog nyob rau hauv cov nqi ntawm cov khoom siv ruaj khov isotope-labeled tshuaj xws li 13CO2 thiab D2O, uas pib nce hauv thawj ib nrab xyoo 2022. Tsis tas li ntawd, tau muaj qhov nce ntxiv hauv cov isotope-labeled biomolecules ruaj khov xws li qabzib. los yog amino acids uas yog ib qho tseem ceeb ntawm cov kab lis kev cai xov xwm ntawm tes.

Kev thov nce ntxiv thiab txo cov khoom xa tuaj ua rau tus nqi siab dua

Dab tsi yog qhov cuam tshuam loj heev rau deuterium mov thiab kev xav tau xyoo dhau los? Cov ntawv thov tshiab ntawm cov tshuaj deuterium-labeled yog tsim kom muaj kev thov rau deuterium.

Deuteration ntawm cov khoom xyaw tshuaj nquag (APIs)

Deuterium (D, deuterium) atoms muaj cov nyhuv inhibitory ntawm cov tshuaj metabolism hauv tib neeg lub cev. Nws tau pom tias yog cov khoom muaj kev nyab xeeb hauv cov tshuaj kho mob. Raws li kev pom ntawm cov tshuaj zoo sib xws ntawm deuterium thiab protium, deuterium tuaj yeem siv los hloov cov tshuaj protium hauv qee cov tshuaj.

Cov nyhuv kho ntawm cov tshuaj yuav tsis cuam tshuam loj heev los ntawm kev ntxiv deuterium. Cov kev tshawb fawb metabolism tau pom tias cov tshuaj muaj deuterium feem ntau khaws tag nrho lub zog thiab muaj zog. Txawm li cas los xij, cov tshuaj uas muaj deuterium yog metabolized qeeb dua, feem ntau ua rau muaj kev cuam tshuam ntev dua, koob tshuaj me me los yog tsawg dua, thiab muaj kev phiv tsawg dua.

Yuav ua li cas deuterium muaj qhov cuam tshuam qeeb ntawm cov tshuaj metabolism? Deuterium muaj peev xwm tsim cov tshuaj tiv thaiv muaj zog hauv cov tshuaj molecules piv rau protium. Muab hais tias cov metabolism hauv cov tshuaj feem ntau cuam tshuam nrog kev rhuav tshem cov ntawv cog lus, cov ntawv cog lus muaj zog txhais tau tias cov tshuaj metabolism qeeb qeeb.

Deuterium oxide yog siv los ua cov khoom pib rau lub cim ntawm ntau yam deuterium-labeled compounds, nrog rau cov khoom siv tshuaj deuterated.

Fiber ntau Optic Cable

Nyob rau theem kawg ntawm kev tsim fiber ntau optic, fiber ntau optic cables raug kho nrog deuterium gas. Qee hom fiber ntau optical muaj qhov cuam tshuam rau kev degradation ntawm lawv cov kev ua haujlwm kho qhov muag, ib qho tshwm sim los ntawm cov tshuaj tiv thaiv nrog atoms nyob rau hauv lossis ib ncig ntawm lub cable.

Txhawm rau daws qhov teeb meem no, deuterium yog siv los hloov qee qhov ntawm cov protium tam sim no hauv cov fiber ntau optic cables. Qhov kev hloov pauv no txo ​​cov tshuaj tiv thaiv tus nqi thiab tiv thaiv kev puas tsuaj ntawm lub teeb xa mus, thaum kawg txuas lub neej ntawm cable.

Deuteration ntawm silicon semiconductors thiab microchips

Cov txheej txheem ntawm deuterium-protium pauv nrog cov roj deuterium (deuterium 2; D 2) yog siv rau hauv kev tsim cov silicon semiconductors thiab microchips, uas feem ntau siv hauv Circuit Court boards. Deuterium annealing yog siv los hloov cov protium atoms nrog deuterium los tiv thaiv cov tshuaj corrosion ntawm nti circuits thiab teeb meem cuam tshuam ntawm cov cab kuj kub.

Los ntawm kev siv cov txheej txheem no, lub neej voj voog ntawm semiconductors thiab microchips tuaj yeem txuas ntxiv thiab txhim kho, tso cai rau kev tsim cov chips me thiab ntau dua.

Deuteration ntawm Organic Light Emitting Diodes (OLEDs)

OLED, ib lub ntsiab lus rau Organic Light Emitting Diode, yog cov khoom siv nyias nyias uas muaj cov khoom siv hluav taws xob semiconductor. OLEDs muaj qhov qis dua tam sim no thiab ci ntsa iab piv rau cov teeb pom kev zoo ib txwm muaj (LEDs). Thaum OLEDs tsis tshua kim los tsim dua li cov qauv LEDs, lawv qhov ci ntsa iab thiab lub neej tsis siab li.

Txhawm rau ua tiav kev hloov pauv kev ua si hauv OLED thev naus laus zis, kev hloov pauv ntawm protium los ntawm deuterium tau pom tias yog txoj hauv kev muaj txiaj ntsig. Qhov no yog vim hais tias deuterium ntxiv dag zog rau cov tshuaj sib txuas hauv cov khoom siv hluav taws xob hauv cov khoom siv hauv OLEDs, uas ua rau muaj ntau yam zoo: Cov tshuaj degradation tshwm sim ntawm tus nqi qeeb, txuas lub neej ntawm lub cuab yeej.
