Co-assembly and Structure of Sodium Dodecylsulfate and other n-Alkyl Sulfates in Glycerol: n-Alkyl Sulfate-Glycerol Crystal Phase

Comparison of surfactant mass transfer with drop formation times from dynamic interfacial tension measurements in microchannels

“…The 52% w/w water-glycerol solution was selected to match the refractive index of the oil phase (n i = 1.39 at 22°C) and avoid any optical distortions from light reflection. All aqueous solutions were prepared on the same day of each experiment in order to avoid undesired reactions between surfactants, water and glycerol [34][35][36].…”

Unusual Structural Insights Revealed by Rheo–SAXS Studies of Nonaqueous Crystalline Gels

“…Here, we have discussed the interesting structural behavior in SDS and glycerol mixtures as the gels undergo shearing using rheo–SAXS. Through previous works ,, and this work, the importance of investigating nonaqueous polar solvents is demonstrated, in particular when probing the self-assembly of amphiphiles. The loss of glycerol from the microfibrils upon foaming has some applications in personal care products and as a type of topical drug delivery architecture as a way of releasing glycerol enriched with active ingredients after long-term storage.…”

“…Previous studies − into the SDS in the glycerol system demonstrated a fibrillar structure on the microscale, with a lamellar nanostructure; the d -spacing of this phase was determined to be d = 5.56 nm. The gel phase is proposed to form as a result of the entanglement of the microfibrils, entrapping free glycerol and increasing the viscosity.…”

“…The structure of the SDS in glycerol gel has been previously investigated in the literature − and is confirmed to have a lamellar nanostructure with a microfibrillar microstructure. The mechanical properties of the gel phase were probed with rheology measurements performed in cone-plate geometry.…”

Effects of alkyl chain length on the cold crystallization of Schiff-base nickel(ii) complexes

“…Therefore, the structures of alkyl derivatives vary depending on the chain length. Accordingly, the alkylation of rigid molecules can alter their physical properties [1][2][3][4][5][6][7][8][9][10][11] significantly, including their thermal properties, [12][13][14][15] crystal structure, [16][17][18][19][20][21] and the structure of adsorbed monolayers. [22][23][24][25][26][27][28] We have analyzed the thermal properties of salen derivatives bearing alkyl chains of variable length and found that those with alkoxy groups adopt a liquid crystalline state at varying temperatures depending on the alkyl chain length.…”
