Particle atomic layer deposition of alumina for sintering yttria‐stabilized cubic zirconiaThe addition of aluminum oxide (Al2O3) as a sintering aid to yttria﹕tabilized zirconia (YSZ) reduces the required densification temperature. Sintering aids are incorporated using a number of processes which can...
Although the pronounced icosahedra can be recognized in the amorphous zone, their number density is apparently lower than that of the crystal matrix. This may be due to some icosahedra directly collapsing during the amorphization or tilting to orientations that cannot be imaged by ABF-STEM. Figure...

In this study, the attitude of some photon absorption energy related parameters such as coherent, Compton, photoelectric, pair-nuclear, pair-electronic, the total mass attenuation coefficients, effective atomic number, and electron density are investigated for two the mixtures, concentrated colemanite and...
and precursor materials. The substrate should have sufficient number of reactive sites to facilitate the ALD growth[25,26]. The minimum deposition temperature for ALD process would be the one which minimizes the physisorption of precursor components[27]and maximum temperature would be the one which ...
The explosion of interest in two-dimensional (2D) materials has spurred advances in catalysis in the confined space between a 2D van der Waals layer and a catalytic surface, as well as ultimate permeation through single atomic layers. An intriguing material in this regard is a 2D silica polymor...
Traditional heterogeneous nanocatalysts are usually prepared by impregnation or coprecipitation methods, resulting in a polydispersity in the number of atoms: nanoparticles, clusters, and even single atoms1. The size of metal species determines the fraction of surface atoms, which has a significant ...
[36]. The two gas–solid surface reactions are self‐limiting or self‐terminating, due to the limited number of surface reactive sites. This nature basically determines the accuracy of ALD in materials growth and its other unique characteristics. The four steps [from 1 to 4 inFig. 2(a),...
