In this review of experimental studies, the retention time and endurance of memristor RRAM memory elements based on reversible resistive switching in oxide dielectrics are studied. The influence of external parameters—switching pulses and ambient temperature—as well as internal factors—evolution of the concentration of oxygen vacancies in the filament region, the material, structure; the thickness of the active dielectric layer, material of metal electrodes on the long-term stability of high resistance state (HRS) and the low resistance state (LRS) of the memristor is discussed.

“…Calcination in air results in the re-dispersion of Pt species to some extent but not fully redispersion. The aggregation of Pt species indicates the spatial separation of Pt and Zn species and the weakening of Pt-Zn interaction [49][50][51], which is not good for PDH reaction. XPS analyses (Fig.…”

“…The O1s peaks in the spectra disclose two kinds of O atoms with different chemical atmosphere existed in the sample. The peaks at 530.01 and 531.68 eV are assigned to the oxygen atoms in lattice and the oxygen atoms in suspending hydroxyl groups, respectively (Ismail et al 2019), and the peak originated from oxygen atoms in adsorbed SO4 2might be too weak to be detected. The relative content of lattice oxygen in SO4 2-/Fe2O3-ZrO2 was 48.5%, while in SO4 2-/ZrO2 was 73.7%.…”

Lignin depolymerization through an oxidation method could provide value-added products, but it is challenging in terms of recovering catalysts or separating products in time to avoid over-oxidation. In this study, a process of selectively oxidative degradation of lignin model compounds was operated in a two-phase reaction system. Lignin model compounds of 4-benzyloxyphenol (PBP) or guaiacylglycerol-β-guaiacyl ether (GGE) in a bottom phase of 1-butyl-3-methylimidazole chloride ([BMIM]Cl) ionic liquid were selectively oxidized by H2O2 in the presence of a solid acid (SO42-/Fe2O3-ZrO2), and the degradation products immediately diffused into the upper organic solvent phase (butyl acetate). In this kind of reaction system, the yield of the products was improved due to the prolonged life of ∙OH in ionic liquid, and the product selectivity was maintained due to the timely product separation, and the ionic liquid and the catalyst were easily recycled.
