Dithiothreitol (DTT), nooc cusub oo wax lagu daro cagaaran ah
Dithiothreitol (DTT), CAS: 3483-12-3, sida reagent cilmi-baarista si weyn loo isticmaalo, waxaa inta badan loo isticmaalaa sidii wakiil yaraynta sulfhydryl DNA, wakiilka deprotecting, iyo dhimista curaarta disulfide ee borotiinada.Nooc cusub oo lagu daro cagaarka ayaa door muhiim ah ka ciyaara hagaajinta waxqabadka batteriga.
Dithiothreitol (DTT) waa wakiil yareyn xoog leh, dib-u-dhisnaantiisa ayaa inta badan sabab u ah xasilloonida qaabaysan ee giraanta lixda xubnood ah (oo ka kooban curaarta disulfide) ee xaaladdeeda oksaydhka.Dhimista curaarta caadiga ah ee disulfide ee dithiothreitol waxay ka kooban tahay laba falcelin beddelka curaarta sulfhydryl-disulfide oo isku xigta.Awoodda dhimista ee dithiothreitol (DTT) waxaa saameeya qiimaha pH, waxayna kaliya ciyaari kartaa saameyn dhimis marka qiimaha pH uu ka weyn yahay 7. Tani waa sababta oo ah kaliya anions thiolate anion-ka deprotonated ayaa fal-celin ah, halka mercaptans aysan sameynin, iyo pKa ee kooxaha mercapto guud ahaan waa 8.3.
Dithiothreitol (DTT) ayaa caadi ahaan loo isticmaalaa si loo yareeyo curaarta disulfide ee molecules borotiinka iyo polypeptides.Caadi ahaan waxaa loo isticmaalaa sida borotiinka difaaca sulfhydryl waxaana loo isticmaalaa diyaarinta tallaalka si looga hortago hadhaaga borotiinka ee cysteine-ka inay sameeyaan disulfides intramolecular iyo intermolecular.furaha.Habka lagu ogaanayo acid nucleic, dithiothreitol (DTT) wuxuu burburin karaa bonds-ka disulfide ee borotiinka RNase, denature RNase, oo fududeeyo habdhaqanka tijaabooyinka sida dhismaha maktabadda RNA iyo xoojinta RNA.Dithiothreitol (DTT) ayaa sidoo kale loo isticmaalaa sidii daawo ka hortag si loo ilaaliyo unugyada iyo unugyada, sida raadiyaha difaaca, iwm.
Si kastaba ha ahaatee, dithiothreitol (DTT) inta badan ma awoodo inay hoos u dhigto curaarta disulfide ee ku dhex jira qaab dhismeedka borotiinka (millaha aan la heli karin).Yaraynta curaarta disulfide ee noocan oo kale ah waxay inta badan u baahan tahay diidmo borotiinka marka hore.
Si loo joojiyo saamaynta shuttle ee baytariyada lithium-sulfur iyo hagaajinta waxqabadka korantada ee baytariyada lithium-sulfur, isku day in aad isticmaasho dithiothreitol (DTT) sida wakiilka dhogorta si aad u xiirto polysulfide-yada sare si ay uga ilaaliso in ay dhalaan.Threitol (DTT) waxaa lagu qasaa waraaqo kaarboon nanotubes ah oo gidaar badan leh (MWCNTs) si loogu diyaariyo dhex dhexaadiyaha DTT.Dhexdhexaadiyaha DTT waxa la dhex dhigayaa inta u dhaxaysa xaashida korantada togan iyo kala soocida badhanka lithium-sulfur nus unug, iyo cufnaanta dusha baaruudda qaada ee xaashida electrode togan Qiyaastii 2mg/cm2.Natiijooyinka indha-indheynta SEM waxay xaqiijinayaan in DTT ay si isku mid ah ugu kala firirsan tahay dusha sare iyo bannaanka warqadda MWCNTs.Natiijooyinka baaritaanka kiimikaadku waxay muujinayaan in baytariga lithium-sulfur ee leh qaab-dhismeedka Sandwich DTT uu leeyahay awood gaar ah oo ugu horreysa oo ah 1288 mAh / g oo ah 0.05C.Marka ugu horeysa, waxtarka coulombic wuxuu ku dhow yahay 100%, awoodda gaarka ah inta lagu jiro dallacaadda iyo sii deynta 0.5C, 2C, iyo 4C heerarka waxay gaaraan 650mAh / g, 600mAh / g, iyo 410mAh / g, siday u kala horreeyaan.Soo bandhigida qaab dhismeedka sandwich-ka DTT ayaa si wax ku ool ah u xiiri kara polysulfide-yada sare.Waxay ka hortagtaa inay u guurto lithium-negative electrode, taas oo ka hortagaysa saameynta shuttle-ga iyo hagaajinta xasilloonida wareegga iyo waxtarka coulomb ee baytariyada lithium-sulfur.
Waxaa xusid mudan in dithiothreitol (DTT) ay tahay walax sun ah.Tusaale ahaan, joogitaanka biraha kala-guurka, dithiothreitol (DTT) waxay u keeni kartaa waxyeelo oksijiin ah unugyada noolaha.Isla mar ahaantaana, dithiothreitol (DTT) ) Waxay sidoo kale kor u qaadi kartaa sunta xeryahooda qaarkood oo ay ku jiraan arsenic iyo meerkuri.Dithiothreitol (DTT) waxay leedahay ur xun, taas oo waxyeello u geysan karta caafimaadka neefsashada iyo taabashada maqaarka.Sidaa darteed, waa lagama maarmaan in la ilaaliyo inta lagu jiro hawlgalka, xidho maaskaro, galoofyada iyo muraayadaha, oo lagu shaqeeyo daboolka qiiqa.
Thithreitol (DTT) oo ah wakiilka xiiraya ee baytariyada lithium-sulfur
Bateriga Lithium-sulfur waxaa loo arkaa inuu yahay nidaam batari leh awood weyn sababtoo ah cufnaanta tamarta sare iyo ilaalinta deegaanka.Si kastaba ha noqotee, "saameynta shuttle" ee polysulfides waxay u horseedaa nolol wareeg ah oo liidata iyo is-daajin halis ah, taas oo xaddidaysa codsigeeda.sabab.
Thiothreitol (DTT) ayaa lagu dari karaa batteriga sidii wakiil xiirid.Waxay si degdeg ah u xiiri kartaa curaarta disulfide heerkulka qolka, xiiri kartaa nidaamka sare ee polysulfides si ay uga hortagto burburkooda, joojiso saamaynta shuttle, iyo kordhiso lithium Waxqabadka korantada ee baytariyada sulfur.
Dithiothreitol (DTT) sida wax lagu daro korantada ee aluminium aluminium/ baytariyada hawada
Batariyada aluminium/hawo ee alkaline, dithiothreitol waxay samayn kartaa lakab ilaalin ah oo isku mid ah oo deggan iyada oo loo marayo bonds firfircoon ee dusha sare ee aluminium anode, waxay joojisaa is-daxalka aluminium anode, oo si wax ku ool ah u wanaajiso waxqabadkeeda.
