The correlation between multiple variable factors and the autocatalytic properties of cerium oxide nanoparticles based on cell viability

Abstract

A new strategy was developed for evaluating the autocatalytic property of Ce NPs under optimized reaction conditions by the PLSR method.

Protein interaction, monocyte toxicity and immunogenic properties of cerium oxide crystals with 5% or 14% gadolinium, cobalt oxide and iron oxide nanoparticles – an interdisciplinary approach

“…For example, Table 3 shows that CeO x :Gd5% and CeO x :Gd14% decreased monocyte viability at the highest tested concentration (1 lg/ mL), whereas Fe 2 O 3 and Co 3 O 4 did not. To our knowledge, monocyte interaction with CeO x :Gd-NPs has not previously been tested but cerium oxide NPs have been found to decrease viability at a similar concentration range Li et al 2018), which is supporting our findings. However, others have found that concentrations of 200 lg/ mL cerium oxide NPs did not affect monocyte proliferation (Lord et al 2012;Ting et al 2013), although the particles used in those studies were coated with APTES and heparin respectively.…”

Pure and Sm doped CeO2 Nanoparticles: An insight into the Room Temperature Ferromagnetism and Photocatalytic Dye Degradation

“…Peak broadening is also observed at 800 °C. The O ads is used to quantify the oxygen vacancies in the system [26,27] . By calculating the integrated area under the curve of O ads , we found that the peak area of O ads is higher for the sample at 800 °C (3712.07), and it is ∼2246.6 for the sample at 500 °C.…”

“…The O ads is used to quantify the oxygen vacancies in the system.

Hence we can conclude that the sample calcined at 800 °C has more oxygen vacancies.…”

Photocatalytic Easy Recovery of Orthophosphates Contaminants in Water Using Amberlite‐732 Cationic‐Resin Exchanged by Ce3+and Ce3+‐Au3+ Species

“…The second O1s photopeak, observed between 531.8 and 532 eV (±0.1 eV), was assigned to adsorbed‐oxygen species at the surface associated to hydroxyls species OH − (O II ). The third peak observed only for Ce‐Au‐Amb‐Ar with the highest BE, located at 533.5 eV (±0.1 eV), was related to the surface adsorbed oxygen of physisorbed water (O III ), according to data provided by literature [30,31] . The relative contribution of these three oxygen surface species depends mainly on the heat treatment.…”

“…The third peak observed only for Ce-Au-Amb-Ar with the highest BE, located at 533.5 eV (� 0.1 eV), was related to the surface adsorbed oxygen of physisorbed water (O III ), according to data provided by literature. [30,31] The relative contribution of these three oxygen surface species depends mainly on the heat treatment. So, the highest contribution of lattice oxygen (O I ) was observed on Ce-Amb-Air surface (61.1 % against 7.8 % for Ce-Amb-Ar).…”
