Qhov kev ruaj ntseg ntawm micelles tuaj yeem xav txog feem ntau ntawm cov ntsuas kub thiab kinetic stability. Thermodynamic stability piav qhia txog yuav ua li cas lub kaw lus ua raws li micelles tsim thiab ncav cuag qhov sib npaug.
Puas micelles ruaj khov?
Ntawm cov polymer siab siab, micelles ruaj khov tshwj tsis yog lawv tau diluted hauv qab CMC. Tom qab ntawd cov micelles yuav disassemble thiab dawb chains rov pom nyob rau hauv cov tshuaj ntau thiab adsorbed ntawm huab cua-dej interface los yog aqueous-organic hnyav interface.
Puas micellar cov kev daws teeb meem puas ruaj khov?
Lub kaw lus yog tsim los ntawm tus kheej, thiab nws yog thermodynamically ruaj khov.
micelles stabilized li cas?
Qhov nrov tshaj plaws covalent crosslinking lub tswv yim suav nrog tsim ntawm covalent bonds / crosslinking nyob rau hauv tshwj xeeb domains ntawm micelle, xws li lub plhaub thiab core domains. Qhov no txhawb nqa qhov tsis muaj zog ntawm kev sib cuam tshuam hauv nruab nrog cev thiab yog li stabilizes micelles.
Dab tsi yog qhov tseem ceeb ntawm thermodynamics ntawm micellization?
Taw qhia. Raws li tau hais ua ntej, cov txheej txheem ntawm micellization yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov tshuaj surfactantthiab yog li nws yog qhov tseem ceeb kom nkag siab txog nws cov txheej txheem (tus tsav tsheb rau kev tsim micelle). Qhov no yuav tsum tau tsom xam ntawm ob qho tib si kinetic thiab qhov sib npaug ntawm cov txheej txheem.

Leej twg ntawm cov phosphorus hauv qab no yog qhov thermodynamically ruaj khov tshaj?
Dub phosphorus yog cov thermodynamically ruaj khov allotropic daim ntawv ntawm phosphorus. Nws ruaj khov ntawm chav tsev kub thiab siab . Qhov twg yog thermodynamically ruaj khov tshaj plaws ntawm phosphorus? Black phosphorus yog cov thermodynamically ruaj khov daim ntawv ntawm phosphorus nyob rau hauv chav tsev kub thiab siab, nrog lub tshav kub ntawm tsim ntawm -39.
Puas yog tsov txaij ntsaws ruaj ruaj nyob?
Raws. Leopard cov ntsaws ruaj ruaj feem ntau nyob hauv lub Antarctic pob dej khovtab sis, thaum lub caij nplooj zeeg thiab lub caij ntuj no cov tsiaj tawg mus rau sab qaum teb thoob plaws hauv Dej Hiav Txwv Sab Qab Teb, qee zaum mus rau New Zealand .
Puas yog ntxhw ntsaws ruaj ruaj?
Pinnipeds yog cov tsiaj nyeg marine nrog cov ceg zoo li fin. Lawv ua pa zoo ib yam li tib neeg thiab lwm yam tsiaj tsiaj, tsiaj reptiles thiab noog, tab sis lawv siv sijhawm nyob rau hauv hiav txwv. Pinnipeds suav nrog "cov ntsaws ruaj ruaj tiag"
Puas yog riam phom nuclear ruaj khov lossis tsis muaj kev ruaj ntseg?
Txoj kev tshawb fawb tau txiav txim siab tias thaum riam phom nuclear txhawb kev ruaj ntseg, thiab tiv thaiv kev ua tsov rog loj, lawv ib txhij tso cai rau kev tsis sib haum xeeb qis dua . Puas yog riam phom nuclear puas ncaj ncees? Kev txwv tsis pub muaj riam phom nuclear yog kev ncaj ncees rau tib neeg, kev ncaj ncees, thiab kev cai lij choj.
Yuav ua li cas txiav txim siab thermodynamically ruaj khov?
Thermodynamic stability nyob ntawm seb qhov tshuaj tiv thaiv yog tus kheej. Qhov no nyob ntawm qhov hloov pauv hauv lub zog dawb (ΔG)Cov tshuaj tiv thaiv thermodynamically ruaj khov yog ib qho uas tsis tshua muaj tshwm sim. Yog li ntawd, nws yog kev ywj pheej ntawm txoj kev ntawm reactants thiab cov khoom .
