Dithiothreitol (DTT), CAS: 34.Ubwoko bushya bwicyatsi kibisi bugira uruhare runini mugutezimbere imikorere ya bateri.
Dithiothreitol (DTT) nigikoresho gikomeye cyo kugabanya, kandi kugabanuka kwayo guterwa ahanini nuburyo bwo guhuza impeta zigizwe nabantu batandatu (zirimo imiyoboro ya disulfide) muburyo bwa okiside.Kugabanuka k'umubano usanzwe wa disulfide na dithiothreitol ugizwe na sulfhydryl-disulfide ebyiri zikurikiranye.Kugabanya imbaraga za dithiothreitol (DTT) bigira ingaruka ku gaciro ka pH, kandi birashobora gusa kugira ingaruka zo kugabanya mugihe agaciro ka pH karenze 7. Ibi ni ukubera ko anion zonyine zidafite imbaraga zikora, mugihe mercaptans itabikora, kandi na pKa yitsinda rya mercapto muri rusange 8.3.
Dithiothreitol (DTT) ikoreshwa muburyo bwo kugabanya imiyoboro ya disulfide ya molekile ya poroteyine na polypeptide.Ubusanzwe ikoreshwa nka poroteyine sulfhydryl ikingira kandi ikoreshwa mugutegura inkingo kugirango ibuze ibisigazwa bya poroteyine sisitemu idashobora gukora disulfide idasanzwe.urufunguzo.Muburyo bwo kumenya aside nucleic, dithiothreitol (DTT) irashobora gusenya imiyoboro ya disulfide iri muri poroteyine ya RNase, kwamagana RNase, no koroshya gukora ubushakashatsi nko kubaka isomero rya RNA no kongera RNA.Dithiothreitol (DTT) ikoreshwa kandi nk'umuti urinda ingirabuzimafatizo, nka radioprotectant, n'ibindi.
Nyamara, dithiothreitol (DTT) akenshi ntishobora kugabanya imiyoboro ya disulfide yashyizwe mumiterere ya poroteyine (solvent idashoboka).Kugabanya iyo nkunga ya disulfide akenshi bisaba kubanza gutandukanya poroteyine.
Kugirango uhagarike ingaruka ziterwa na bateri ya lithium-sulfure no kunoza imikorere yamashanyarazi ya bateri ya lithium-sulfure, gerageza gukoresha dithiothreitol (DTT) nkumukozi wogosha kugirango wogoshe polysulfide yo murwego rwo hejuru kugirango wirinde gushonga.Threitol (DTT) ivangwa mu mpapuro nyinshi za karubone nanotubes (MWCNTs) kugirango itegure DTT interlayer.Interineti ya DTT ishyirwa hagati yurupapuro rwiza rwa electrode no gutandukanya buto ya lithium-sulfure igice cya selile, hamwe nubuso butwara sulfure yubucucike bwurupapuro rwiza rwa electrode Hafi ya 2mg / cm2.Ibisubizo byo kureba SEM byemeza ko DTT ikwirakwijwe kimwe hejuru yubusa nubusa bwimpapuro za MWCNTs.Ibisubizo by'ibizamini by'amashanyarazi byerekana ko bateri ya lithium-sulfure ifite DTT sandwich ifite ubushobozi bwo gusohora bwa mbere ubushobozi bwa 1288 mAh / g ku gipimo cya 0.05C.Ku nshuro yambere, imikorere ya coulombic yegereye 100%, kandi ubushobozi bwihariye mugihe cyo kwishyuza no gusohora kuri 0.5C, 2C, na 4C igera kuri 650mAh / g, 600mAh / g, na 410mAh / g.Kwinjiza imiterere ya sandwich ya DTT birashobora gukata neza polysulfide yo murwego rwo hejuru.Irinda kwimukira muri lithium itari nziza ya electrode, bityo ikabuza ingaruka zogutwara no kunoza uruzinduko no gukora neza kwa coulomb ya bateri ya lithium-sulfure.
Birakwiye ko tumenya ko dithiothreitol (DTT) ari ibintu byuburozi.Kurugero, imbere yibyuma byinzibacyuho, dithiothreitol (DTT) irashobora kwangiza okiside yangiza molekile yibinyabuzima.Muri icyo gihe, dithiothreitol (DTT)) Irashobora kandi kongera uburozi bwibintu bimwe na bimwe birimo arsenic na mercure.Dithiothreitol (DTT) ifite impumuro mbi, ishobora kwangiza ubuzima bitewe no guhumeka no guhuza uruhu.Niyo mpamvu, birakenewe kubirinda mugihe cyo gukora, kwambara masike, gants na gogles, no gukorera mumashanyarazi.
Thithreitol (DTT) nkigikoresho cyo kogosha muri bateri ya lithium-sulfure
Batiri ya Litiyumu-sulfure ifatwa nka sisitemu ya batiri ifite imbaraga nyinshi kubera ubwinshi bw’ingufu nyinshi no kurengera ibidukikije.Nyamara, "ingendo ya shitingi" ya polysulfide iganisha ku buzima bubi bwikurikiranya no kwikuramo cyane, bigabanya ikoreshwa ryayo.impamvu.
Thiothreitol (DTT) irashobora kongerwaho muri bateri nkigikoresho cyo kogosha.Irashobora gukata byihuse imiyoboro ya disulfide ku bushyuhe bwicyumba, kogosha polysulfide yo mu rwego rwo hejuru kugirango irinde isenyuka ryayo, ikabuza ingaruka za shitingi, kandi ikongerera lithium Imikorere y’amashanyarazi ya batiri ya sulferi.
Dithiothreitol (DTT) nk'inyongera ya electrolyte muri bateri ya alkaline / bateri yo mu kirere
Muri bateri ya alkaline ya aluminium / ikirere, dithiothreitol irashobora gukora urwego rumwe kandi ruhamye rwo kurinda binyuze mu miyoboro ya covalent ihuza imbaraga hejuru ya anode ya aluminium, ikabuza kwangirika kwa anode ya aluminium, kandi igateza imbere imikorere yayo neza.
