“…Various studies have been conducted using natural materials, such as beach sand and agricultural waste to produce high purity silica extracts. This beach sand has a more dominant silica concentration than other oxides (Ismail et al, 2020;Eddy et al, 2015;Okereafor et al, 2020;Rattanaudom et al, 2020). Several studies have shown the results of high purity silica extraction in di erent sand extraction areas.…”

Silica has become a popular material due to its high abundance and many advantages in various fields. This material can be produced synthetically and extracted from nature with resultant advantages in the application of green production. Therefore, this article deals with the form of silica extracted from quartz sand, leaves, and agricultural wastes found in nature. The extraction process from various sources would be described using thermal, biological, and chemical methods. This review also highlights the potential application of silica as a photo catalytic antibacterial-supporting material and discusses its role in increasing the effectiveness of the process. The discussion was continued with research on this procedure, where synthetic auxiliary materials were compared to the extracted silica. Furthermore, results obtained indicated that the extracted material had very good potential as a photocatalyst adjunct in its application in the antibacterial field.

“…After PV 2.5, the surfactant adsorption still increased but with a lower value of the slope. From our previous study, the ζ-potential value of the sand surface was a negatively charged surface with −21 mV at pH = 9.0 . Since the surface of Ottawa sand is hydrophilic and negatively charged, there would exist the repulsion between the sand surface and the negatively charged surfactant head groups.…”

“…Among these anionic surfactants, carboxylate extended surfactants offer a great alternative to other conventional anionic surfactants, including sulfonate surfactants. Their unique structure contains intermediate polarity groups of ethylene oxide (EO) or propylene oxides (PO), facilitating the balancing of the surfactant molecules penetrated at the interfaces (e.g., air–water, oil–water), thus improving foaming properties even in the presence of crude oil and increased brine concentrations . Nitrogen gas is one of the most common carrier gases used widely in foam flooding owing to it being an inexhaustible gas and low cost and flow resistance in a porous medium .…”

The use of silica nanoparticles (SNPs) has shown promising results in providing higher foam stability in chemically enhanced oil recovery (cEOR). In this study, hydrophobic SNPs stabilized in a carboxylate anionic surfactant were selected to improve the performance of surfactant foam flooding through the sand pack experiment. The effects of SNPs on foam flooding, including foam stability, surfactant adsorption, wettability alteration, and displacement efficiency, were investigated. The results confirmed that the addition of SNPs significantly enhanced foam stability. The surfactant adsorptions onto the sand medium were reduced by 54 and 27% in the presence of SNPs at 5000 and 1000 ppm, respectively. The addition of the SNP−surfactant could alter the wettability of the oilcoated surface to water-wet conditions as probed by the contact angle measurement. The displacement efficiency reached a cumulative recovery of 97.58% original oil in place (OOIP) by the SNP foam flooding system at 1000 ppm SNPs compared to 77% OOIP obtained from the neat surfactant foam system. Gas chromatography−time-of-flight−mass spectrometry (GC−TOF−MS) analysis was adopted to characterize the incremental change in crude oil compositions at each pore volume to probe the flooding performance in correspondence with the oil properties, i.e., waxy components. As a result of combining the effects of the SNP−surfactant on improving the foam stability, surface alteration, and minimizing the surfactant loss, more available surfactants could efficiently sweep the residual waxy and heavy oil components. The findings of this study revealed an understanding of improving oil displacement of waxy crude oil by SNP−surfactant-stabilized foam, which is applicable for waxy crude oil reservoirs.

Amphiphiles and surfactants are surface-active molecules with special properties at interfaces, and they can undergo different modes of self-association forming colloidal entities in solution. They can also stabilize other colloidal dispersions including nanoparticles, and help the formation and protection of nanodispersions resulting from chemical reactions. In this study, we have discussed the formation, properties, and applications of such nanocolloid-like species formed in solution by different methods with special stress on various types of surfactants. Nanoparticles show the difference in melting point, electrochemical properties, conductance, etc., from their corresponding bulk material. Classical thermodynamics is used to explain this property. The basics of such processes, their types, morphology, stability, and usefulness have been presented and discussed. The types of assemblies that arise from the selfassociations of the amphiphiles, and surfactants under different conditions (i.e., micelles, reverse micelles, vesicles, liposomes, niosomes, etc.) have been also presented. Examples of their types, morphologies, transformations, and applications in relation to the stability, and functions of nanodispersions or nanocolloids are exemplified with multiple illustrations from earlier as well as recent research. The use of biosurfactants and block copolymers is also discussed. The stabilization of nanoparticles by "capping" has been discussed in some detail. A short account of the hydrothermal and solvothermal processes of synthesis of nanomaterials using amphiphiles as templates has been also presented. The multiple applications of amphiphile-mediated nanoscience have been briefly presented and discussed.
