The aim of this research was to determine the effect of calcination temperatures on the ratio of atomic weight of Al/O that could affect the formation of γ-Al2O3 phase. The novelty of this research is how to produce γ-Al2O3 in single phase and nanosize by simple method (sol-gel ...

Iodide migration causes degradation of the perovskite solar cells. Here, we observe the direct migration of iodide into the hole-transport layer in a device. We demonstrate that ultrathin room temperature atomic layer-deposited Al2O3 on the perovskite surface very effectively hinders the migration....
The size of these dots is in the range of 2–3 Å, indicating that each bright dot corresponds to one individual Co atom. The enlarged view of the selected region (Fig. 3c) reveals that each Co atom is centred by the light elements (C, N and/or O). Additional STEM images are...
2) No, in the strict sense, Schottky cannot exist in K2O if we consider this type of defect to consist of a cation-anion pair; for every O2- vacancy created there must exist two K+ vacancies.Concept Check 5.2Question: What point defects are possible for MgO as an impurity in Al2O3?
In addition to DACs, several theoretical investigations proved that triple-atom catalysts such as F e3/Al2O3(010) [209] and F e3–GDY/Gra [210] are NRR-active. The synthe- sis of Ru3 triple-atom catalysts was reported with a confined pyrolysis method within MOFs [211], and...
Femtosecond laser damage resistance of oxide and mixture oxide optical coatings We report on the laser damage resistance of ion beam鈥攕puttered oxide materials (Al2O3, Nb2O5, HfO2, SiO2, Ta2O5, ZrO2) and mixtures of Al2O3-SiO2, Nb2O5-... B Mangote,L Gallais,M Commandré,... ...
Silica composites [8,9], Al2O3 nanocomposites [10], and ZrO2 nanocomposites [11] also exhibited higher resistance to AO; however, they require complicated homogenization processes for dispersion in the epoxy making their application in composite materials used in actual space structures difficult. ...
By alternate removal of Al2O3 sacrificial spacers to release nanotubes replicated from the AAO template, multiple-walled coaxial nanotubes of five nested layers were synthesized within AAO templates. The resultant coaxial nanotube structures are highly ordered and absolutely conformal with the template ...
Cobalt aluminate, CoAl2O4, and Al2O3–CoAl2O4 solid solutions (at Co:Al=1:4, and Co:Al=1:8) were prepared by hydrolysis of mixed metal alkoxides, followed ... CO Arean,M. Penarroya Mentruit,EE Platero - 《Materials Letters》 被引量: 126发表: 1999年 Satellite Tracking of White-...
