Viscosities were measured for the ternary systems Y(NO 3 ) 3 +La(NO 3 ) 3 +H 2 O, La(NO 3 ) 3 +Ce(NO 3 ) 3 +H 2 O, and La(NO 3 ) 3 +Nd(NO 3 ) 3 + H 2 O and their binary subsystems Y(NO 3 ) 3 +H 2 O, La(NO 3 ) 3 +H 2 O, Ce(NO 3 ) 3 +H 2 O, and Nd(NO 3 ) 3 +H 2 O at 293.15, 298.15 and 308.15 K. The results were used to test the applicability of simple equations for the viscosity of the mixed solutions. The predictions agreed well with measured values, implying that the viscosities of the examined electrolyte solutions could be related to those of their constituent binary solutions using these simple equations.

A high-throughput screening method for rapid laboratory evaluation of corrosion inhibitors was developed based on microarray consisting of up to 200 droplets of corrosion inhibitor solutions on one carbon steel substrate. The extent of corrosion on the steel under each single droplet was studied by tracking the variation of the 3D morphology of the corrosion product. Using this high-throughput screening platform, we evaluated the corrosion inhibition effect of benzotriazole and Ce(NO 3 ) 3 mixture and identified their best mixing ratio. The enhanced inhibition of the inhibitor mixture was discussed based on the corrosion experimental data and the molecular dynamic simulation.

In this study, a new self-healing strategy that can simultaneously recover the corrosion resistance and the adhesion strength of coatings was introduced. The coating was based on a shape memory epoxy resin containing ethylene vinyl acetate (EVA) microspheres loaded with Ce(NO 3 ) 3 inhibitors, and was cured at a relatively high temperature to facilitate the fusion of adjacent microspheres for a strengthened self-healing effect. The electrochemical impedance spectroscopy (EIS) and scanning electrochemical microscopy (SECM) results demonstrated that the shape memory effect of epoxy matrix, the filling of molten EVA microspheres as well as the release of Ce(NO 3 ) 3 inhibitors contributed synergistically to suppress the corrosion reaction at the coating damage. After healing, the low frequency impedance modulus of the coatings containing Ce(NO 3 ) 3 -EVA microspheres was three orders of magnitude higher than that of the blank epoxy coating. The adhesion strength of the coatings containing Ce(NO 3 ) 3 -EVA microspheres on the metal substrate was also largely repaired thanks to the strong bonding effect of the EVA microspheres.

Conductivities were measured for the ternary systems Y(NO3)3 + Ce(NO3)3 + H2O, Y(NO3)3 + Nd(NO3)3 + H2O, and Ce(NO3)3 + Nd(NO3)3 + H2O and their binary subsystems Y(NO3)3 + H2O, Ce(NO3)3 + H2O, and Nd(NO3)3 + H2O at (293.15, 298.15, and 308.15) K. The measured conductivities were used to test the generalized Young’s rule and the semi-ideal solution theory. The comparison results show that the generalized Young’s rule and the semi-ideal solution theory can yield good predictions for the conductivities of the ternary electrolyte solutions, implying that the conductivities of aqueous solutions of (1:3 + 1:3) electrolyte mixtures can be well predicted from those of their constituent binary solutions by the simple equations.

In this report, hybrid silica sol–gel coating was prepared using Ce(NO 3 ) 3 (Sol-Ce) as catalyst. Structure, surface morphology and anticorrosion ability of Sol-Ce solution/coating were studied by infrared spectroscopy (IR), scanning electron microscopy, energy dispersive spectrometer (EDS), potentiodynamic scan (PDS) and electrochemical impedance spectroscopy (EIS). IR results showed that Ce(NO 3 ) 3 had a stronger influence on reactivity of alkoxysilane. EDS results revealed that the fraction of Fe in Sol-Ce coating was significantly lower than regular acid-catalyzed hybrid silica sol–gel coating (Sol-Ac) and Sol-Ac with Ce(NO 3 ) 3 -doped coating (Sol-Ac/Ce). The results of PDS and EIS demonstrated that Sol-Ce coating had better anticorrosion ability than Sol-Ac and Sol-Ac/Ce on carbon steel. The enhanced anticorrosion performance of the Sol-Ce coating might result from the following two reasons: (a) Ce(NO 3 ) 3 as a catalyst could alleviate the negative effects of low pH with using acid catalyst (dissolution of carbon steel) and (b) Ce(NO 3 ) 3 could impede corrosion of carbon steel as corrosion inhibitor.

All-solid-state lithium metal batteries (LMBs) have attracted extensive attention because of their high energy density and good safety performance. But the ionic conductivity at low temperature and dendritic growth hinder their further development. In this work, a flexible all solid-state electrolyte consisted with Ce(NO 3 ) 3 , lithium bis(fluorosulfonyl) imide (LiFSI), and poly(ethylene oxide) (PEO) is synthesized. Ce(NO 3 ) 3 as an effective additive can enhance the ionic conductivity of solid polymer electrolytes (SPEs) by regulating Li + transporting and stabilizing the interface between lithium metal anode and electrolyte by forming a stable and uniform solid electrolyte interphase (SEI) on lithium metal anode surface. The as-prepared electrolyte exhibits a good ionic conductivity of 1.6 × 10 −4 S cm −1 at 60 °C and a wide electrochemical window of 4.4 V . The Li//Li symmetric cell with PEO + LiFSI+1%Ce(NO 3 ) 3 electrolyte displays a long cycling lifespan of over 1100 h at 0.1 mA cm −2 at 60 °C. Moreover, the corresponded LiFePO 4 (LFP)//Li cell exhibits a long cycling lifespan of 300 cycles and excellent rate capability. This work proposes an effective additive to improve ionic conductivity and stabilize the Li metal/electrolyte interface.

The predictions of the simple equations agree well with measured values, indicating that the densities of the examined electrolyte solutions can be well predicted from those of their constituent binary solutions by the simple equations.
