No, micelle formation tsis tshwm sim hauv ethanol vim tias cov alkyl saw ntawm xab npum tau soluble hauv cawv. Li no, micelle tsim tshwm sim nyob rau hauv dej raws li hnyav tsis nyob rau hauv ethanol.
Yuav ua li cas micelle yuav tsim nyob rau hauv txhua hom kuab tshuaj?
Micelles tuaj yeem tsim tsuas yog ncig cov roj molecules ntawm cov roj sib tov. Ethanol yog cov kuab tshuaj zoo heev thiab nws tuaj yeem yaj cov roj los tsim cov tshuaj ntshiab.
micelle tsim tshwm sim nyob qhov twg?
Micelles yog tsim los ntawm nws tus kheej sib dhos ntawm amphiphilic molecules. Cov qauv muaj thaj tsam hydrophilic/polar (lub taub hau) thiab hydrophobic/nonpolar cheeb tsam (tail) [1]. Micelles yog tsim nyob rau hauv aqueous tov qhov twg thaj av polar ntsib sab nraud ntawm micelle thiab cheeb tsam nonpolar tsim cov tub ntxhais.
Qhov twg tsis tuaj yeem tsim micelle?
Kev sib dhos ntawm amphiphilic polymers ua rau tsim cov Nanomicelles (NMs) nrog cov tub ntxhais hydrophobic thiab lub plhaub hydrophilic [42]. … Kev tshawb fawb, chitosan molecules tam sim no tsis muaj amphiphilic zog thiab, yog li, tsis tuaj yeem tsim micelles hauv dej.
Yuav ua li cas molecules tsim tau ib tug micelle?
Ib lub micelle yog tsim thaum ntau yam ntawm cov molecules suav nrog xab npum thiab tshuaj ntxuav tes ntxiv rau hauv dej. Cov molecule tej zaum yuav yog fatty acid, ntsev ntawm fatty acid (xws li xab npum), phospholipids, los yog lwm yam molecules zoo sib xws. Lub molecule yuav tsum muaj lub cev muaj zog "lub taub hau" thiab tsis yog-polar hydrocarbon saw "tail".
