29, we explore its activity contribution from high electrochemical surface area (ECSA) and evaluate its activity by high kinetic current density (Jk). Supplementary Fig. 30 shows that impurity of amorphous oxide before acid pickling is not the active mass since the ORR activity is enhanced after...
This is because the O concentration in Ti by Mg/magnesium oxide (MgO) equilibrium at 1200 K is approximately 2 mass% in the standard state33, which is significantly higher than the 0.180 mass%. In recent years, several studies have been conducted on the deoxidation of Ti using M...
essential as a preparatory layer for the LDH coating.Fig. 3B shows the cross sections adjacent to the surface after different processes. HTO scaffolds showed an oxide film approximately 1.5 μm thick. According toFig. 3C, a plethora of precipitates exist in the grains and at the grain ...
However, divalent magnesium ions experience significant electrostatic barriers at interfaces in such metal oxide cathodes, leading to sluggish solid-state diffusion of magnesium ions and slow interfacial charge transfer [10]. Ion mobility is further impeded in some commonly used electrolytes such as ...
Magnesium will form a product hydroxide/oxide film when exposed to aqueous environments [17]. Santamaria et al. [18] found an ultra-thin MgO inner layer and a Mg(OH)2 external layer for pure magnesium after immersion in NaCl solution. Generally, Materials 2018, 11, 970; doi:10.3390/ma1...
The conductive filler particles can be divided into carbon-based, metal-based, and conductive metal oxide-based particles. Epoxy resins, phenolic resins, and acrylate can be used as the matrix resin, and among these, epoxy resins have advantages of low shrinkage, high cohesion, and a high ...

prepared the Mg-Al-CO3 LDH (layered double hydroxide) compound and found that it possessed excellent properties of friction and wear reduction as lubricating oil additive [24]. In this paper, magnesium perrhenate, as a novel inorganic double metal oxide, was synthesized, characterized, and its ...
