Antioxidant and cell-friendly FeTiO nanoparticles for food packaging application.

An emerging technology of active packaging enables prolongation of food shelf life by limiting the oxygen transfer and the reactivity of free radicals, which both destruct food freshness. In this work, FeTiO nanoparticles were synthesized using a modified sol-gel method and evaluated as an enforcement of alginate food packaging film. Pure phase FeTiO nanoparticles had an average particle size of 44 nm and rhombohedral morphology.

Exploring the impact of calcination parameters on the crystal structure, morphology, and optical properties of electrospun FeTiO nanofibers.

Nanostructured FeTiO (pseudobrookite), a mixed metal oxide material holds significant promise for utilization in energy and environmental applications. However, its full application is still hindered due to the difficulty to synthesize monophasic FeTiO with high crystallinity and a large specific surface area. Herein, FeTiO nanofibers were synthesized a versatile and low-cost electrospinning method, followed by a calcination process at different temperatures.

Electrospun Nickel Manganite (NiMnO) Nanocrystalline Fibers for Humidity and Temperature Sensing.

Nickel manganite nanocrystalline fibers were obtained by electrospinning and subsequent calcination at 400 °C. As-spun fibers were characterized by TG/DTA, Scanning Electron Microscopy and FT-IR spectroscopy analysis. X-ray diffraction and FT-IR spectroscopy analysis confirmed the formation of nickel manganite with a cubic spinel structure, while N physisorption at 77 K enabled determination of the BET specific surface area as 25.
