		<title>Synthesis and characterization of a fatty acid self-assembled monolayer on CeO2 nanoparticles: to explore solution-state property of a SAM</title>
		<description><![CDATA[Decanoic acid self-assembled monolayer (SAM) in the quasi-crystalline state was prepared on the surface of the cubic ceria nanoparticles (6.5 ± 1.1 nm) by hydrothermal synthesis. The purification method to obtain quasi-crystalline SAM without residual (free) decanoic acid was developed. The SAM was carefully washed (purified) and characterized carefully by FT-IR, TG, DSC, and NMR. [...]]]></description>

		<title>Nanocrystalline ceria: Synthesis, structure-sensitive properties, and promising applications</title>
		<description><![CDATA[Directed search for further manifestations of size-dependent effects in the functional properties of nanomaterials constitutes a key line of nanotechnologies research. The major size-dependent effects were analyzed for nanocrystalline ceria. The practically significant techniques for preparation of ceria nanopowders with controllable micromorphology were analyzed. Selected promising applications of this material were described.

		<title>Nanoceria as Antioxidant: Synthesis and Biomedical Applications</title>
		<description><![CDATA[The therapeutic application of nanomaterials has been a focus of numerous studies in the past decade. Due to its unique redox properties, cerium oxide (ceria) is finding widespread use in the treatment of medical disorders caused by the reactive oxygen intermediates (ROI). The radical-scavenging role of ceria nanoparticles (nanoceria) have been established, as well as [...]]]></description>

		<title>Protection from radiation-induced pneumonitis using cerium oxide nanoparticles</title>
		<description><![CDATA[In an effort to combat the harmful effects of radiation exposure, we propose that rare-earth cerium oxide nanoparticles (free-radical scavengers) protect normal tissue from radiation-induced damage. Preliminary studies suggest that these nanoparticles may be a therapeutic regenerative nanomedicine that will scavenge reactive oxygen species, which are responsible for radiation induced cell damage. The effectiveness of [...]]]></description>

		<title>Origin of Anomalous Lattice Expansion in Oxide Nanoparticles</title>
		<description><![CDATA[Anomalous lattice expansions have been measured for the first time in monodisperse ceria nanoparticles and in barium titanate single nanoparticles by electron diffraction. X-ray photoelectron spectroscopy studies on ceria nanoparticles and ab initio computer simulation on barium titanate clusters show that the origin of expansion is the decrease of electrostatic force caused by valence reduction [...]]]></description>

		<title>Cerium and yttrium oxide nanoparticles are neuroprotective</title>
		<description><![CDATA[The responses of cells exposed to nanoparticles have been studied with regard to toxicity, but very little attention has been paid to the possibility that some types of particles can protect cells from various forms of lethal stress. It is shown here that nanoparticles composed of cerium oxide or yttrium oxide protect nerve cells from [...]]]></description>

		<title>Synthesis of Biocompatible Dextran-Coated Nanoceria with pH-Dependent Antioxidant Properties</title>
		<description><![CDATA[Biocompatible dextran-coated nanoceria (cerium oxide nanoparticles) are found to exhibit excellent, pH-dependent antioxidant properties. They provide cytoprotection from free radicals to normal cells but not to cancer cells, and thus have potential applications in antioxidant and anti-inflammatory coatings for prosthetic devices and tissue engineering and in improved cancer therapeutics.

		<title>On the origin of the lattice constant anomaly in nanocrystalline ceria</title>
		<description><![CDATA[The lattice parameter of nanocrystalline ceria films prepared by sputtering was monitored as a function of annealing temperature. Within the temperature range of 150–420°C, an equilibrium with atmospheric oxygen is established within a few hours, whereas grain growth does not occur. On the basis of the experimental results and analysis of literature data, we present [...]]]></description>

		<title>Synthesis and Characterization of Stable Aqueous Ceria Sols</title>
		<description><![CDATA[Stable colloidal aqueous dispersions (sols) of cerium (IV) oxide of uniform size distribution were obtained by forced hydrolysis of cerium (IV) ions in the presence of diluted sulfuric or nitric acids. Synthesis of ceria sols was carried out using two commercially available precursors: cerium(IV) sulfate and cerium(IV) nitrate. The precursors were dissolved in different concentrations [...]]]></description>

		<title>Superoxide dismutase mimetic properties exhibited by vacancy engineered ceria nanoparticles</title>
		<description><![CDATA[In this report ceria nanoparticles are shown to act as catalysts that mimic superoxide dismutase (SOD) with the catalytic rate constant exceeding that determined for the enzyme SOD.
Показано, что наночастицы оксида церия способны выступать в роли катализатора, схожего по своим свойствам с супероксиддисмутазой. Установлено, что скорость каталитической реакции на наночастицах оксида церия превосходит скорость реакции [...]]]></description>
