Cov dej kas yog cov sib xyaw ua ke los ntawm hydrogen nrog lwm cov khoom. Lawv muaj ntau cov ntawv thov hla rau ntau qhov kev lag luam vim lawv cov khoom tshwj xeeb. Ib qho ntawm cov ntawv thov feem ntau ntawm cov dej kas yog nyob hauv teb ntawm lub zog cia thiab tiam.
Cov dej kas yog siv hauv cov tshuab hydrogen cia, uas yog qhov tseem ceeb rau kev txhim kho ntawm hydrogen roj roj hlwb. Cov roj roj roj no yog lub zog huv thiab muaj txiaj ntsig zoo, thiab cov dej kas ua si lub luag haujlwm tseem ceeb hauv kev khaws cia thiab tso tawm hydrogen rau siv hauv cov hlwb no. Daim ntawv thov no ntawm cov dej kas yog qhov tshwj xeeb tshaj yog hauv kev txhim kho cov kev daws teeb meem loj thiab txo kev cia siab rau cov pob txha roj av.
Lwm daim ntawv thov tseem ceeb ntawm cov dej kas yog hauv kev tsim cov tshwj xeeb alloys. Qee hydrides qee yam yog siv los ua cov khoom siv hydrogen cia hauv kev tsim cov tshwj xeeb xws li kev lag luam suav nrog aerospace, thiab electronics. Cov alloys muaj lub zog siab thiab lub teeb ci, ua rau lawv cov khoom siv tseem ceeb rau kev tsim cov khoom lag luam tshaj lij.
Hydrides kuj pom cov ntawv thov hauv thaj teb ntawm kev siv tshuab nuclear. Hydrides yog siv ua cov tubrogras thiab cuam tshuam hauv nuclear reactors, uas lawv pab tswj tus nqi ntawm kev siv hluav taws xob nuclear thiab paub txog kev nyab xeeb thiab kev ua haujlwm ntawm cov reaors. Ib qho ntxiv, cov dej kas yog siv nyob rau hauv kev tsim cov khoom lag luam, kev siv xov tooj cua hauv hydrogen siv hauv kev siv hluav taws xob nucrear.
Hauv kev thaj teb ntawm chemistry, cov dej kas yog siv los ua cov neeg sawv cev hauv ntau yam kev tawm tsam. Lawv kuj tau siv hauv cov synthic thiab cov ntaub ntawv tsim khoom lag luam. Ib qho ntxiv, qee cov kas dej muaj cov ntawv thov hauv kev lag luam semiconduct, uas lawv tau siv rau hauv cov khoom siv hluav taws xob thiab cov khoom siv.
Zuag qhia tag nrho, cov ntawv thov ntawm cov dej kas yog muaj sib txawv thiab cuam tshuam thoob plaws ntau yam kev lag luam. Los ntawm lub zog cia rau kev tsim tshwj xeeb, tshuab hluav taws xob, thiab tshuaj lom neeg ua si lub luag haujlwm thev naus laus zis thiab kev tsim kho tsav tsheb hauv ntau thaj teb. Raws li kev tshawb nrhiav thiab kev loj hlob hauv daim teb ntawm cov dej sib txuas ntxiv, lawv cov ntawv thov yuav tsum nthuav ntxiv, pab txhawb rau kev nce qib ntawm kev nce qib thiab cov thev naus laus zis.
