The abundance of cerium in natural resources, its ability to absorb UV light while being transparent visible light, as well low photocatalytic activity make ceria (CeO2) a promising candidate for filter material sunscreens. Doping with different elements can further decrease catalytic and activity, thus preventing the <br /> degradation other sunscreen ingredients. In this work, pure zinc...

CeO2 nanoparticles (CeO2 NPs) which are used as a diesel fuel additive are emitted in the particulate phase in the exhaust, posing a health concern. However, limited information exists regarding the in vivo acute toxicity of CeO2 NPs on multiple organs. Presently, we investigated the acute (24 h) effects of intratracheally instilled CeO2 NPs in mice (0.5 mg/kg) on oxidative stress, inflammation...

In recent years, ceria and doped-ceria anisotropic nanocrystals (NC’s) have been produced by a variety of solution-based synthetic routes. The motivation in producing ceria-based NCs with controlled morphology is to develop high surface area catalyst supports with well-defined exposed crystal planes that exhibit optimal catalytic activity. Understanding the growth mechanism of CeO2 NC’s is vita...

Engineered nanoparticles are widely incorporated into a large number of consumer products due to their specific physico-chemical properties in comparison to bulk materials. Cerium dioxide nanoparticles (CeO2) are currently used in several applications: as a component of catalytic converters, as a UV blocking or polishing agent or as a diesel fuel additive. The fate of engineered nanoparticles i...

ultrasonic-assisted method was applied for preparation of cu+2-doped zns nanoparticles (mole fractions of cu+2 ions are 0.000, 0.015, 0.030 and 0.060) in water as a template-free and green method at 30 min. the prepared nanoparticles were investigated by powder x-ray diffraction (xrd), scanning electron microscopy (sem), energy dispersive x-ray (edx) and uv–vis diffuse reflectance spectra (drs)...

Correction for 'One step in situ synthesis of CeO2 nanoparticles grown on reduced graphene oxide as an excellent fluorescent and photocatalyst material under sunlight irradiation' by Animesh Kumar Ojha et al., Phys. Chem. Chem. Phys., 2015, DOI: .

An electrochemical sensor incorporating a signal enhancement for the determination of lead (II) ions (Pb2+) was designed on the basis of the thrombin-binding aptamer (TBA) as a molecular recognition element and ionic liquid supported cerium oxide (CeO2) nanoparticles-carbon nanotubes composite modification. The composite comprises nanoparticles CeO2, multi-wall carbon nanotubes (MWNTs) and hydr...

Dissipative particle dynamics (DPD) was carried out to study the nucleation and crystal growth process of CeO2 nanoparticles in different alcohol aqueous solutions. The results showed that the nucleation and crystal growth process of CeO2 can be classified into three stages: nuclei growth, crystal stabilization and crystal aggregation except the initial induction stage, which could be reproduce...

Objective- The healing effect of chitosan supported cerium oxide nanoparticles (nano-CeO2) on cutaneous experimental excisional wound infected with pseudomonas aeruginosa was studied in rat. Design- Experimental Study. Animals- Sixty male albino rats. Procedures- The chitosan supported nano-CeO2 hydrogel was prepared and characterized using Fourier-transform infrared spectro...

Gene therapy is a promising technique for the treatment of various diseases. The development of minimally toxic and highly efficient non-viral gene delivery vectors is the most challenging undertaking in the field of gene therapy. Here, we developed dimethyldioctadecylammonium bromide (DODAB)-nanoceria (CeO2) hybrids as a new class of non-viral gene delivery vectors. These DODAB-modified CeO2 n...
