Dithiothreitol (DTT) isimba rakasimba rekudzikisa, uye kudzikisira kwayo kunonyanya kukonzerwa nekugadzikana kwekugadzikana kwemhete ine nhengo nhanhatu (ine disulfide bonds) mune yayo oxidation mamiriro.Kudzikiswa kweyakajairwa disulfide bond ne dithiothreitol ine maviri akateedzana sulfhydryl-disulfide bond exchange reaction.Simba rinoderedza re dithiothreitol (DTT) rinobatwa nehuwandu hwepH, uye inogona kungoita kuderedza kuderedza kana pH inokosha kupfuura 7. Izvi ndezvokuti chete deprotonated thiolate anions inoshanda, nepo mercaptans isingaiti, uye iyo pKa yemapoka e-mercapto inowanzoita 8.3.
Dithiothreitol (DTT) inowanzoshandiswa kuderedza disulfide zvisungo zveprotein molecules uye polypeptides.Inowanzoshandiswa seprotein sulfhydryl inodzivirira uye inoshandiswa mukugadzirira kwekudzivirira kudzivirira mapuroteni cysteine masara kubva pakuumba intramolecular uye intermolecular disulfides.key.Mukuita kwekuonekwa kwenucleic acid, dithiothreitol (DTT) inogona kuparadza disulfide zvisungo muRPAse protein, denature iyo RNase, uye kufambisa maitiro ekuyedza senge RNA raibhurari kuvaka uye RNA amplification.Dithiothreitol (DTT) inoshandiswawo semushonga wekudzivirira maseru uye matishu, seradioprotectant, nezvimwe.
Zvisinei, dithiothreitol (DTT) kazhinji haikwanisi kuderedza zvisungo zve disulfide zvakaiswa muprotein structure (solvent isingasviki).Kuderedzwa kwezvisungo zvakadaro zve disulfide kazhinji kunoda denaturation yeprotein kutanga.
Kuti udzivise kuvharwa kwemabhatiri e-lithium-sulfur uye kuvandudza kushandiswa kwe electrochemical ye lithiamu-sulfur mabhatiri, edza kushandisa dithiothreitol (DTT) semushonga wekuveura kugera-high-order polysulfides kudzivirira kuti irege kupera.Threitol (DTT) inosanganiswa mune yakawanda-yakavakirwa kabhoni nanotubes (MWCNTs) bepa kugadzira DTT interlayer.DTT interlayer inoiswa pakati peyakanaka electrode sheet uye separator ye lithiamu-sarufa bhatani hafu-sero, uye sarufa-inotakura pamusoro density yeyakanaka electrode sheet About 2mg/cm2.SEM mhedzisiro yekutarisa inosimbisa kuti DTT yakapararira zvakafanana pamusoro uye voids yepepa reMWCNTs.Electrochemical test results inoratidza kuti lithium-sarufa bhatiri ine DTT sandwich chimiro ine yekutanga kuburitsa yakananga kugona kwe1288 mAh/g pamwero we0.05C.Kekutanga, iyo coulombic inoshanda iri pedyo ne100%, uye iyo chaiyo chiyero panguva yekuchaja uye kubuda pa 0.5C, 2C, uye 4C mitengo inosvika 650mAh / g, 600mAh / g, uye 410mAh / g, zvichiteerana.Iko kuunzwa kweiyo DTT sandwich chimiro inogona kunyatso kugera yakakwira-odha polysulfides.Iyo inodzivirira kuti irege kutamira kune lithium negative electrode, nokudaro ichidzivisa iyo shuttle effect uye inovandudza kutenderera kugadzikana uye coulomb kushanda kwe lithiamu-sarufa mabhatiri.
Zvinokosha kucherechedza kuti dithiothreitol (DTT) chinhu chepfu.Semuenzaniso, pamberi pekuchinja kwesimbi, dithiothreitol (DTT) inogona kukonzera kukuvara kweoxidative kune biological molecules.Panguva imwecheteyo, dithiothreitol (DTT) ) Inogonawo kuwedzera huturu hwemamwe makomisheni ane arsenic uye mercury.Dithiothreitol (DTT) ine hwema hunonhuwa, hunogona kukuvadza hutano nekuda kwekufema uye kubata ganda.Naizvozvo, zvinodikanwa kuti uzvidzivirire panguva yekushanda, pfeka masiki, magurovhosi uye magirazi, uye ushande mufume hood.
Thithreitol (DTT) sechinhu chekuveura mumabhatiri e-lithium-sarufa
Lithium-sarufa bhatiri inoonekwa sebhatiri system ine simba rakakura nekuda kwekuwanda kwayo kwesimba uye kuchengetedza kwezvakatipoteredza.Nekudaro, iyo "shuttle mhedzisiro" ye polysulfides inotungamira kune hurombo kutenderera hupenyu uye kwakakomba kuzviburitsa, izvo zvinotadzisa kushandiswa kwayo.chikonzero.
Thiothreitol (DTT) inogona kuwedzerwa kubhatiri seanogera.Inogona kukurumidza kugera disulfide zvisungo pakupisa kwekamuri, shear high-order polysulfides kudzivirira kuparara kwavo, inhibit the shuttle effect, uye kuwedzera lithium The electrochemical performance ye sulfur mabhatiri.
Dithiothreitol (DTT) sekuwedzera kwe electrolyte mu alkaline aluminium / mabhatiri emhepo.
Mu alkaline aluminium/air mabhatiri, dithiothreitol inogona kuumba yunifomu uye yakagadzikana inodzivirira layer kuburikidza ne dynamic covalent bond pamusoro pearuminiyamu anode, inhibit self-corrosion yealuminum anode, uye zvinobudirira kuvandudza kushanda kwayo.
