Synthesis of Oligomeric Silicone Surfactant and its Interfacial Properties
Applied Sciences, 2019 During the exploitation of low permeability gas-condensate reservoirs, the mud filtrate, acidizing liquid, and fracturing fluid invade the reservoir and condensate gas, severely reducing the permeability of the reservoirs due to increased capillary ...

Smart worm-like micelles responsive to CO₂/N₂ and light dual stimuli [PDF]
, 2017 CO₂/N₂ and light dual stimuli-reponsive worm-like micelles (WLMs) were obtained by addition of a relatively small amount of a switchable surfactant, 4-butyl-4´-(4-N,N-dimethylhexyloxy-amine) azobenzene bicarbonate (AZO-B6-CO₂), sensitive to the same ...

Critical Micelle Concentration of Surfactant Using Hadkar Factor [PDF]
Indian Journal of Pharmaceutical Education and Research, 2015 Critical micelle concentration is an important characteristic property of a surfactant and various methods such as osmotic pressure, surface tension, interfacial tension, UV-Visible spectrophotometry have been reported to determine it. The drop weight method was used to determine the Hadkar factor H 1 for organic liquid lighter than water and Hadkar ...
