“…Different mineral oil/water ratios and a range of concentrations of titania NPs functionalized by (3-aminopropyl)-triethoxysilane (APTES) Pickering emulsions were prepared. Titania dioxide (TiO 2 or titania) NPs are eco-friendly Pickering stabilizers ( Waghmode et al, 2019 ), with diameters of less than 100 nm ( Negi et al, 2021 ). For example, ultrafine TiO 2 is used in sunscreens because it can block UV radiation but stay transparent on the skin ( Negi et al, 2021 ).…”

This study presents an individual encapsulation of fungal conidia in an oil-in-water Pickering emulsion at a single-conidium encapsulation yield of 44%. The single-conidium encapsulation yield was characterized by analysis of confocal microscopy micrographs. Mineral oil-in-water emulsions stabilized by amine-functionalized titania dioxide (TiO2-NH2 or titania-NH2) particles were prepared. The structure and the stability of the emulsions were investigated at different compositions by confocal microscopy and a LUMiSizer® respectively. The most stable emulsions with a droplet size suitable for single-conidium encapsulation were further studied for their individual encapsulation capabilities. The yields of individual encapsulation in the emulsions; i.e., the number of conidia that were individually encapsulated out of the total number of conidia, were characterized by confocal microscopy assay. This rapid, easy to use approach to single-conidium encapsulation, which generates a significantly high yield with eco-friendly titania-based emulsions, only requires commonly used emulsification and agitation methods.

“…Chemical flooding systems involving mixtures of inorganic nanoparticles (SiO 2 , Al 2 O 3 , TiO 2 , and CuO) and synthetic polymers demonstrate increased salt and temperature tolerance in EOR operations. − Recently, dispersions containing inorganic nanoparticles (NPs) and CNFs also exhibited improved rheological and emulsion stability performance than CNFs alone . The addition of SiO 2 and ZnO NPs showed a detrimental effect on CNF (0.4 wt %, −37.5 mV ζ potential) dispersion viscosity.…”

The increasing energy demand worldwide pushes the exploration of new and efficient ways to improve crude oil recovery and processing. From a chemical perspective, the petroleum industry relies on a wide range of specialty additives to provide the necessary fluid qualities for up-, mid-, and downstream operations. Currently, most of these compounds come from synthetic sources. However, attention is steadily turning to highperformance new materials derived from natural sources to improve the efficiency and productivity of the petroleum industry while reducing its environmental impacts. Cellulose is an abundant, renewable, and biodegradable material with outstanding chemical versatility. Cellulose structural modifications result in numerous products, with some as old as paper, textiles, explosives, and texturizing agents and others as new as functional nanostructures. This minireview focuses on nanocellulose-based materials as high-performance agents for enhanced oil recovery and emulsion stabilization/destabilization in the petroleum industry.

“…Common dispersants include water, organic solvent (such as ethanol), active agent, etc. These dispersants can properly change the viscosity of the matrix [17][18]. For example, when resin substances in the paint are used as the matrix, the filler can be uniformly and stably dispersed in it by adding an appropriate amount of ethanol.…”

Corrosion is a common phenomenon. Both natural environment and industrial media may cause corrosion of metals. It is reported that every 90 seconds around the world, 1 ton of steel corrosion into rust, pipeline corrosion not only causes the transmission medium run, leakage phenomenon, bring huge waste, but also endanger health. Corrosion is not only an economic problem, but also a safety problem. The explosion caused by corrosion and the collapse of steel structures will bring accidents to people, endanger people's property and health safety. Corrosion not only affects the working accuracy of national defense facilities and equipment, but even causes the failure of key precision components, which seriously threatens national security. In this paper, the structure and properties of NM and the research status of nanomaterial complexes are introduced. It is pointed out that it is possible to improve the properties of composite coatings by adding different dimensional NP in epoxy powder coatings. It is suggested that powder coating instead of solvent coating will be a developing trend in metal AC application in the future. Through the experimental study, it was found that the main performance indexes of the nano composite epoxy powder coating prepared by the synergistic action of nano particle modification, ball milling mixing and melting mixing extrusion were improved in different degrees compared with the ordinary pure epoxy powder coating.
