Piezo-, photo- and piezophotocatalytic activity of electrospun fibrous PVDF/CTAB membrane

open access: yesChimica Techno Acta, 2022
A composite material based on polyvinylidene fluoride (PVDF) nanofibers modified with cetyltrimethylammonium bromide (CTAB) was synthesized by coaxial electrospinning. The morphology and structure of the material were studied by SEM, FTIR spectroscopy, X-

Effects of Bentonite Nanoclay and Cetyltrimethyl Ammonium Bromide Modified Bentonite Nanoclay on Phase Inversion of Water-in-Oil Emulsions

open access: yesColloids and Interfaces, 2020
The effects of unmodified and modified bentonite nanoclays (with various degrees of surfactant modification) on the catastrophic phase inversion from water-in-oil (W/O) emulsion to oil-in-water (O/W) emulsion were determined experimentally. The bentonite

Influence of Surfactant Type, Surfactant Concentration, and Salinity on Interfacial Tension of a Brine/Live Oil/Surfactant Fluid System: A Case Study of Iranian Asmari Oil Reservoir [PDF]

open access: yesIranian Journal of Oil & Gas Science and Technology, 2017
The chemical surfactant flooding can mobilize the trapped oil by lowering the interfacial tension between oil and brine and in some cases altering the reservoir rock wettability.

Force Spectroscopy of DNA-Ctab Aggregates [PDF]

open access: yesBiophysical Journal, 2015
Aggregates of oligonucleotides and the surfactant, CTAB, have been studied with force spectroscopy using an atomic force microscope. Gold coated AFM tips were derivatized with long carbon chain thiols and thiols functionalized with carboxylic acid and amine head groups and used to measure the strength of interaction or adhesive force between the AFM ...
