“…Simpraditpan et al [101] produced titanate nanofibers using a hydrothermal method and a natural ilmenite mineral as the starting material. Cao et al [102] described a one-step hydrothermal method for the successful synthesis of WO3 nanofibers (~100 nm in diameter, and length up to tens of micrometers). The main advantages of hydrothermal methods are the mild reaction conditions and the good crystallization of the obtained materials.…”

Nanofiber unique characteristics and potential applications offer innovative strategies and opportunities for sustainable energy production, and for creative solutions to biomedical, healthcare, and environmental problems. This review summarizes the history and development of nanofiber technology, their unique properties, fabrication techniques (using spinning and nonspinning approaches), and emerging applications in energy harvesting and storage, environmental protection and improvement, and biomedical technology and healthcare.Nanofibers are currently used as electrode and membrane materials for batteries, supercapacitors, fuel cells, and solar cells. Nanofiber membranes are also successfully used for ultra-high air filtration, wastewater treatment, water purification, and blood purification at low pressure. This review will describe the different types of nanostructured fibers (e.g., solid, mesoporous, hollow, core-shell nanofibers) fabricated from natural and synthetic polymers, metal and metal oxides, carbon-based, inorganic-organic hybrid nanofibers and their potential applications. Moreover, it will highlight the current and future research needs in nanofiber-based materials to improve and broaden their applications and commercialization.

“…The morphology, alignment, density, aspect ratio, and crystalline quality of the materials that were prepared by sol-gel are directly related to the seed layer parameters [46]. Recent investigations have shown that the hydrothermal growth using different chemical solutions is another efficient method for the preparation of pure and doped oxide materials with various shapes (nanorods, nanofibers, nanowires, and nanosheets) [50][51][52][53]. The morphology of the structures during the preparation process is changed depending on the solution composition, the reaction temperature, and time [6,54].…”

Metal oxide materials have been applied in different fields due to their excellent functional properties. Metal oxides nanostructuration, preparation with the various morphologies, and their coupling with other structures enhance the unique properties of the materials and open new perspectives for their application in the food industry. Chemical gas sensors that are based on semiconducting metal oxide materials can detect the presence of toxins and volatile organic compounds that are produced in food products due to their spoilage and hazardous processes that may take place during the food aging and transportation. Metal oxide nanomaterials can be used in food processing, packaging, and the preservation industry as well. Moreover, the metal oxide-based nanocomposite structures can provide many advantageous features to the final food packaging material, such as antimicrobial activity, enzyme immobilization, oxygen scavenging, mechanical strength, increasing the stability and the shelf life of food, and securing the food against humidity, temperature, and other physiological factors. In this paper, we review the most recent achievements on the synthesis of metal oxide-based nanostructures and their applications in food quality monitoring and active and intelligent packaging.

“…3) [47,48], and then leads to the accelerated growth of hexagonal-prism WO 3 along the [001] direction and the formation of hierarchical (NH 4 ) 0.33 WO 3 •H 2 O nanoplates. The nanoplates self-assemble together to form microspheres to reduce the high surface energy [49]. However, it may be due to the addition of doped ions (Zr 4+ , Y 3+ and Cl -) into hydrothermal system, the breakage of order between the positive and negative charge destroys the self-assemble process, leading to the transformation of agglomerated microspheres into relatively dispersed cotton-like precursor.…”
