The characteristic peaks locate at 2θ = 28.6, 33.1, 47.4, 56.3, 59.2, 59.5, 76.6 and 79.0 degrees corresponding to (111), (200), (220), (311), (222), (400), (331) and (420) lattice planes of CeO 2 , respectively [23,26]. By using the standard data JCPDS 34-0394, it can be concluded that the obtained peaks in XRD pattern presented planes of a cubic fluorite structure (space group: Fm3m) of CeO 2 .…”

Abstract. The present work investigated the corrosion protection performance of Ce(III) activated-cerium(IV) oxide nanoparticles for carbon steel in a NaCl solution. Ceria nanoparticles were synthesized by homogeneous precipitation in ethanol/water mixed solvent. The obtained CeO 2 nanoparticles were characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM). The corrosion inhibition action of the activated nanoparticles by cerium(III) ions on carbon steel in NaCl solution was evaluated by electrochemical measurements (electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization). Then, the effect of cerium salt activated-CeO 2 on the protection properties of poly-vinyl-butyral (PVB) coating deposited onto carbon steel plate was studied by salt spray test. The obtained results showed that the salt activated-nanoparticles are anodic corrosion inhibitors. The presence of Ce(III) activated CeO 2 in the coating improved the barrier properties and corrosion protection performance of the PVB coating. No swellings of coating were observed after 48 hours of exposure in salt spray chamber.

"Optical fluorescent spider silk electrospun nanofibers with embedded cerium oxide nanoparticles," J. Nanophoton. 12(2), 026016 (2018), doi: 10.1117/1.JNP.12.026016. Abstract. The work demonstrates an electrospun nanocomposite of recombinant spider silk protein (rSSp) nanofibers with embedded cerium oxide (ceria) nanoparticles. RSSP (MaSp1) has been produced, extracted from goat milk, and fabricated into nanofibers using an electrospinning process. The resulting electrospun nanofibers have a mean diameter of ∼50 nm. Furthermore, ceria nanoparticles of mean diameter <10 nm were added in the spinning dope to be embedded within the generated nanofibers. These nanoparticles show certain optical activity due to optical trivaliant cerium ions, associated with formed oxygen vacancies. The formed nanocomposite shows promising mechanical properties such as the Young's modulus, elasticity (or elongation at break), and toughness. In addition, the electrospun mat becomes fluorescent with 520-nm emission upon exposure to UV light, due to excitation of the optically active ceria nanoparticles. Also, the formed nanocomposite shows a decay of its electric resistance over time upon exposure to cyclic loads at different humidity conditions. The synthesized nanocomposite can be utilized in different biomedical, textile, and sensing applications.

Abstract:The lubricants added with nanoparticle additives have achieved a predominant position in the field of research on development of sustainable lubricating oils. The efficient physical and chemical properties of metal oxide nanoparticles as lubricant additives have widely extended its purview. The surface morphology and stability analysis of nano-sized Ceria (CeO 2 )and Ceria-Zirconia (Ce-Zr) hybrid nanoparticles are carried out using High Resolution Transmission Electron Microscopy (HR-TEM), Fourier Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD) and Zeta Potential (ZP) analyses techniques. The ceria-based nanoparticles are synthesized through the bottom-up approach of chemical processing named Precipitation Method (PM). The better control on particle size of PM resulted in refined and spherically shaped nanoparticles. Further, to improve the dispersion stability of the prepared nanoparticles in the lubricant, a suitable surfactant namely Polysorbate 20 (Tween 20) was used. The characterization results proved that the ceria-based nanoparticles can play an important role in improving the lubricating properties of the base-oil, provided that proper measures are taken to compensate for its minimal undesirable effects.
