Stability enhancement effect of normal long-chain alcohols on ion pair amphiphile monolayers at the air/water interface

A Dendritic Amphiphile for Efficient Control of Biomimetic Calcium Phosphate Mineralization

“…Although this study focuses on the effect of pH and not temperature, the approach is conceptually similar, because changes of the pH change the number of hydrogen bonds available for monolayer stabilization. Of course, some amphiphile dissolution into the subphase during the compression/expansion cycles is not uncommon . Although the reasons for the hysteresis are not understood, the data prove that the monolayer is very stable.…”

On the characteristics of mixed Langmuir monolayer templates containing dipalmitoyl phosphatidylcholine for gold nanoparticle formation

“…With the condensing effect, the monolayer template stability might be enhanced, as suggested by a monolayer study of mixed two-tailed ion pair amphiphile/longchain alcohol systems [24]. In addition, the distribution of HD molecules in a DPPC monolayer would reduce the induced electrostatic interactions between DPPC molecules associating with AuCl 4 − and thus contribute to the monolayer template stability.…”

“…It has been reported that DPPC was miscible with HD at the air/liquid interface due to the attractive interaction and well-packed arrangement between the molecules [22,23]. By adding HD in a DPPC monolayer, one may improve the monolayer stability through the effects of attractive interaction and well-packed arrangement between the monolayerforming molecules [24]. In addition, since HD is miscible with DPPC at the interface, one is able to adjust the distribution of DPPC molecules in the monolayer templates by the addition of HD, which will be useful for the monolayer template applications.…”

Effect of straight-chain alcohols on the physicochemical properties of calcium lignosulfonate

“…Sulfomethylation and oxidation can improve the dispersive ability of CL on concrete suspensions, but hydroxymethylation weakens the dispersive ability of CL on According to Bedö et al [17], organic alcohol can favor the micelle formation in aqueous solutions of ethoxylated nonyl-phenols. Li et al [18] have reported that normal long-chain alcohols can enhance the stability of ion pair amphiphile monolayers at the air/ water interface. Patist et al [19] have studied the effects of longchain alcohols on the micelle stability of sodium dodecyl sulfate (SDS) solutions and the physicochemical properties of SDS, such as foaming ability, dynamic and equilibrium surface tension, and surface viscosity.…”
