20.500.12556/DKUM-90889 Structure and potential application of surfactant-free microemulsion consisting of heptanol, ethanol and water Microemulsions, which are thermodynamically stable and isotropic mixtures of water, oil, and surfactants, attract significant research interest due to their unique physicochemical properties and diverse industrial applications. Traditional surfactant-based microemulsions (SBMEs) stabilize the interface between two typically immiscible liquids, forming various microstructures such as oil-in-water (O/W) droplets, water-in-oil (W/O) droplets, and bicontinuous phases. However, the use of surfactants poses environmental concerns, cost implications, and potential toxicity. Consequently, there is increasing interest in developing surfactant-free microemulsions (SFMEs) that offer similar benefits without the drawbacks associated with surfactants. In this study, we explore the formation and characteristics of a new surfactant-free microemulsion in a ternary system comprising water, ethanol, and heptanol. Advanced techniques are employed to characterize the microstructures and stability of surfactant-free microemulsions. These include electrical conductivity measurements, surface tension analysis, dynamic light scattering (DLS), and Fourier transform infrared spectroscopy (FTIR). These methods have been extensively used in previous research on surfactant-free microemulsions (SFMEs) to reveal the properties and interactions within microemulsion systems. The area of interest is identified using these techniques, where silica nanoparticles are subsequently synthesized and then visualized using transmission electron microscopy (TEM). surfactant-free microemulsions ternary system nanoparticles mikroemulzije brez površinsko aktivnih snovi trojni sistem nanodelci true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/2504-5377/8/5/53 © 2024 by the authors Članek v reviji 2024-10-02 03:12:44 2024-10-03 09:15:55 2024-12-09 13:04:10 0000-00-00 00:00:00 2024 0 0 14 str. iss. 5, [article no.] 53 Vol. 8 Sept. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-07-19 2024-09-10 2024-09-14 544.72 209555203 10.3390/colloids8050053 2504-5377 colloids-08-00053_(1).pdf colloids-08-00053_(1).pdf 1 595F0E30702628357F0CE89B23D5DB14 393b0e5b918e5af1b0c0303efe23cb6ee72591a595fa8073e6e41762fb4b66e7 e1ac1afe-8161-11ef-a574-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=186203 https://www.mdpi.com/2504-5377/8/5/53 0 ee69ee62-8161-11ef-a574-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=186204 Fakulteta za strojništvo 0 0 0
