In this work, thin film yttria-stabilized zirconia [YSZ] solid electrolytes were sputtered onto insulating substrates at room temperature and 600oC in order to produce different average grain sizes (~15-50 nm). For reference, polished samples of single crystal and bulk, poly-crystalline YSZ were also used. Platinum film electrodes were then sputtered on top and lithographically patterned to giv...

در این مقاله پس از فرمول­بندی و ساخت لایه­های ضخیم ysz8  و ysz8-ni5/1 توسط روش چاپ سیلک روی زیرپایه آلومینایی، مقدار بندگپ در اثر افزودن اکسید نیکل با نمونه بدون دوپنت و همچنین حساسیت این حسگرها نسبت به بخار اتانول مورد بررسی و مقایسه قرار گرفت. از اهداف این پژوهش بررسی و مقایسه مقدار بندگپ، انرژی فعالسازی، تغییرات حساسیت، زمان پاسخ و بازیابی می­باشد. نتایج نشان می­دهد که نمونه بدون دوپنت نسبت ...

In the present work, surface characterization of YSZ/Al2O3 /CeO2 plasma sprayed coatings was performed to understand characteristics. The content Yttria-stabilized zirconia (YSZ) 60 wt.% , where alumina varied from 30 38 and CeO2 2 10 wt.%, respectively. Ceramic with a different percentage variation composite materials were used increase layer strength on substrate SS-304. SEM micrographs analy...

Investigation of the charge dynamics and roles cocatalysts is crucial for understanding reaction photocatalytic water splitting on semiconductor photocatalysts. In this work, photogenerated electrons in Ga2O3 loaded with Cr2O3-Rh was studied using time-resolved mid-infrared spectroscopy. The structure these identified high-resolution transmission electron microscopy CO adsorption Fourier-transf...

Use of indigestible markers such as Cr2O3, Fe2O3, and TiO2 are commonly used in animal studies to evaluate digesta rate of passage and nutrient digestibility. Yet, the potential impact of indigestible markers on fecal microbial ecology and subsequent VFA generation is not known. Two experiments utilizing a total of 72 individually fed finishing pigs were conducted to describe the impact of diet...

Thermal Barrier Coatings are subjected to spallation and destabilization due to hot corrosion.Recently, Ceria Stabilized Zirconia (CSZ)-based TBCs have been intensively investigated for the YSZreplacement because CSZ has a much lower thermal conductivity and a higher expected thermalexpansion coefficient than those of YSZ. In this research, Yttria stabilized zirconia (YSZ) andceria stabilized z...
