網頁The imperative need for highly performant and stable p-type transparent electrodes based on abundant metals is stimulating the research on perovskite oxide thin films. Moreover, exploring the preparation of these materials with the use of cost-efficient and scalable solution-based techniques is a promising approach to extract their full potential. Herein, … 網頁Explanation : Iron (III) oxide is a neutral compound, which implies the net charge of the compound equals 0; i.e. the charges of all the atoms must add up to 0. Oxygen in nearly …
http://sjlin.dlearn.kmu.edu.tw/12 網頁The Fe2O3 NPs absorb the light and may act as thermal antennae, dissipating energy to the vicinal mineral phase. Such a photothermal process triggers the sintering and densification of the surrounding calcium phosphate crystals thereby forming a new, dense layer of typically ∼20 μm in thickness, which is bonded to the underlying surface of the natural …
