“…The scattering experiments were performed on a SANS diffractometer at Dhruva reactor-BARC, India, which uses a velocity selector-monochromatized beam of mean wavelength (λ) 5.2 Å with a resolution (Δλ/λ) of ∼10%. The angular distribution of the scattered neutrons was recorded using a linear 1 m-long He one-dimensional position-sensitive detector (PSD). Here, the tested sample solutions were placed in a 0.5 cm quartz cell cuvette with Teflon stoppers, and the scattering measurements were recorded at the required temperature and corrected on an absolute scale.…”

“…Cationic surfactants exhibit a wide range of self-assembled geometries ranging from spherical micelles to short rods (ellipsoidal) or long cylinders to entangled worm-like micelles, vesicles, and liquid crystalline edifices, giving an account of their concentration in aqueous solution. Studies have reported that these nanoscale morphologies can be fine-tuned by altering the solution environment in the presence of various organic/inorganic additives (anionic hydrotropes, short chain surfactants, salts, etc.) manipulating the temperature, pH, ionic strength, etc. Such alteration in micellar characteristics impart them the ability to serve as smart materials with excellent potential for rheology control, enhanced oil recovery, delivery of hydrophobic bioactive molecules, etc. However, to achieve microstructures of higher order, such as worm-like micelles, vesicles, or liquid crystals, the appropriate selection of additives is very crucial.…”

“…Cationic surfactants display a varied range of self-assemblies in aqueous solution, viz., spherical, cylindrical/rodlike micelles, wormlike vesicles, and liquid crystals. Such nanoscale micellar structure can also be achieved under the influence of several additives, such as salts, solvents, acids, amines, etc., added to surfactant solutions that enable them to exhibit a wide range of applications in the field of pharmaceuticals, enhanced oil recovery, cosmetics, dyeing, foaming, etc. …”
