Hot reformate gas produced by reforming of heavy fuels, such as JP-8, must be desulfurized prior to its use in a solid oxide fuel cell (SOFC). This requires development of sorbent materials with high sulfur absorption efficiency and capacity at the SOFC operating temperature (650-800 C) to avoid heat exchanger penalties. Sorbent performance stability in cyclic operation of sulfidation and regen...

There is a growing attention to enhance the performance of solid oxide fuel cell (SOFC) electrodes through incorporation nano-catalyst materials within electrodes’ active sites. In this study, we report technique for increased efficiency and microstructural control infiltration process polymerized norepinephrine (pNE) treatment. Nano-CeO2 catalysts were incorporated both commercial anode-suppor...

Abstract Cerium oxide nanoparticles have unique catalytic and oxygen storage capacity properties. In this work, the morphology size of cerium were experimentally theoretically investigated. For synthesis nanoparticles, laser ablation method was used. The analysis morphological characteristics performed using transmission electron microscopy. Using molecular dynamics, we reveal limiting dimensio...

nano-sized drugs have better distribution than their identical forms. magnesium is the cofactor of various enzymes in lipid and glucose metabolism. in this study the effect of nano-magnesium oxide (nano-mgo) on glucose concentration and lipid profile in diabetes induced mice was evaluated in 21 laboratory mice. mice were divided randomly into three equal groups (control, treatment and placebo)....

The effect of nanomaterials on biota under realistic environmental conditions is an important question. However, there is still a lack of knowledge on how different illumination conditions alter the toxicity of some photocatalytic nanomaterials. We have investigated how environmentally relevant UV-A exposure (intensity 8.50 ± 0.61 W/m(2), exposure dose 9.0J/cm(2)) affected the toxicity of ceriu...

For the first time, we considered Mn oxide/C60 composites as water-oxidizing catalysts. The composites were synthesized by easy and simple procedures, and characterized by some methods. The water-oxidizing activities of these composites were also measured in the presence of cerium(iv) ammonium nitrate. We found that the nanolayered Mn oxide/C60 composites show promising activity toward water ox...

In this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. The electrochemical properties of the produced electrode are studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques in 3M NaCl, NaOH, and KOH electrolytes. Scanning electron microscopy (SEM) is used to characterize the mi...

The first target of any therapy for retinal neurodegeneration is to slow down the progression of the disease and to maintain visual function. Cerium oxide or ceria nanoparticles reduce oxidative stress, which is known to play a pivotal role in neurodegeneration. Our aim was to investigate whether cerium oxide nanoparticles were able to mitigate neurodegeneration including microglial activation ...
