TL;DR: In this article, it was demonstrated that the addition of a second inert oxide (ZrO2) to the active RuO2 layer on a titanium substrate substantially increased the service life of DSA-type anodes with respect to oxygen gas evolution.

TL;DR: In this article, a mixed oxide (Al2O3)1−x(Ga2O 3)x alloy coating, prepared via atomic layer deposition (ALD), on Li[Ni0.5Mn0.3Co0.2]O2 (NMC) cathodes is developed that has increased electron conductivity and demonstrated an improved rate performance in comparison to uncoated NMC.
Abstract: Metal oxide coatings can improve the electrochemical stability of cathodes and hence, their cycle-life in rechargeable batteries. However, such coatings often impose an additional electrical and ionic transport resistance to cathode surfaces leading to poor charge–discharge capacity at high C-rates. Here, a mixed oxide (Al2O3)1–x(Ga2O3)x alloy coating, prepared via atomic layer deposition (ALD), on Li[Ni0.5Mn0.3Co0.2]O2 (NMC) cathodes is developed that has increased electron conductivity and demonstrated an improved rate performance in comparison to uncoated NMC. A “co-pulsing” ALD technique was used which allows intimate and controlled ternary mixing of deposited film to obtain nanometer-thick mixed oxide coatings. Co-pulsing allows for independent control over film composition and thickness in contrast to separate sequential pulsing of the metal sources. (Al2O3)1–x(Ga2O3)x alloy coatings were demonstrated to improve the cycle life of the battery. Cycle tests show that increasing Al-content in alloy coat...

TL;DR: In this paper, a series of CeO2-ZrO2−CrOx mixed oxides with different Ce/Zr molar ratios were synthesized by co-precipitation method and tested for deep catalytic oxidation of 1,2-dichloroethane (DCE), as one of the typical chlorinated VOCs pollutants.

TL;DR: In this paper, a theoretical impedance function is deduced for a proposed mechanism of passive film formation of steel in contact with alkaline aqueous media involving two reaction intermediates: mixed oxide with similar stoichiometry to magnetite and Fe(III)-oxides.
