CrystalExplorer (CE) is a freeware designed to analysis the crystal structure with *.cif file format. [1]CE is helpful to investigate different areas of solid-state chemistry such as Hirshfeld surface analysis, intermolecular interactions, polymorphism, effect of pressure and temperature on crystal structure, single-crystal to single-crystal reactions, analyzing the voids present in crystal ...
To decrease free energy of the system the surfactant is precipitated out. CMC is determined by establishing inflection points for pre-determined surface tension of surfactants in solution. Plotting the inflection point against the surfactant concentration will provide insight into the critical micelle concentration by showing stabilization of ...
The micelle packing parameter equation is utilized to help "predict molecular self-assembly in surfactant solutions": [10] v o a e ℓ o {\displaystyle {\frac {v_{o}}{a_{e}\ell _{o}}}} where v o {\displaystyle v_{o}} is the surfactant tail volume, ℓ o {\displaystyle \ell _{o}} is the tail length, and a e {\displaystyle a_{e}} is the ...
CM is the concentration of the micelle in the mobile phase (total surfactant concentration - critical micelle concentration) A plot of 1/k¢ verses CM gives a straight line in which KSW can be calculated from the intercept and KMW can be obtained from the ratio of the slope to the intercept. Finally, KSM can be obtained from the ratio of the ...
A mixture of soap and water is an everyday example of a lyotropic liquid crystal. Biological structures such as fibrous proteins showings relatively long and well-defined hydrophobic and hydrophilic ‘‘blocks’’ of aminoacids can also show lyotropic liquid crystalline behaviour. [6]
Soap is a common household amphiphilic surfactant compound. Soap mixed with water (polar, hydrophilic) is useful for cleaning oils and fats (non-polar, lipophilic) from kitchenware, dishes, skin, clothing, etc.
In colloidal and surface chemistry, the critical micelle concentration (CMC) is defined as the concentration of surfactants above which micelles form and all additional surfactants added to the system will form micelles. [1] The CMC is an important characteristic of a surfactant.
Ammonium lauryl sulfate (ALS) is the INCI name and common name for ammonium dodecyl sulfate (CH 3 (CH 2) 10 CH 2 OSO 3 NH 4). The anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group. The combination of nonpolar and polar groups confers surfactant properties to the anion: it facilitates dissolution of both polar and non ...
