Hydrophobic study of increasing alkyl chain length of platinum surfactant complexes: synthesis, characterization, micellization, thermodynamics, thermogravimetrics and surface morphology

Abstract

This paper contains details on the synthesis, characterization, physicochemical properties and surface morphology of five supramolecular metallosurfactants (SMMSs).

Philic–phobic chemical dynamics of a 1st tier dendrimer dispersed o/w nanoemulsion

“…Surface tensions and viscosities of the prepared nanoemulsions were estimated by pendant drop number and viscous ow time, respectively, with a Borosil Mansingh Survismeter [24][25][26][27] (calibration no. 06070582/1.01/C-0395, NPL, India) at 293.15 to 313.15 K. The temperature of the survismeter was controlled by a Lauda Alpha KA 8 thermostat to AE0.05 K. The pendant drop number was counted with an electronic counter, while the viscous ow time was recorded with an electronic timer with an accuracy of AE0.1 s. The Survismeter was properly washed with acetone and dried completely before the viscosity and surface tension measurements.…”

Amphiphilic azobenzenes: Antibacterial activities and biophysical investigation of their interaction with bacterial membrane lipids

“…As it was commonly observed with surface-active molecules [19] including alkyl derivatives of quaternary ammonium compounds [20,21], an increase in the length of the nonpolar alkyl chain reduces the value of the CMC. The γ CMC observed for the 4b-4d compounds are similar and much lower than that observed for 4a.…”

Soybean oil derived-process oil prepared via recyclable organocatalysis for eco-friendly styrene–butadiene rubber composites

“…2d further reflect the greater repulsion of the filler particles caused by the incorporation of longer aliphatic chains when we compare the SBR/PASO99 and SBR/UASO90 (Δ G ′ = 1102 kPa) composites with SBR/VASO90 (Δ G ′ = 1659 kPa). 49…”
