Temperature plays an important role in promoting the corrosion of metals. The Arrhenius plot can interpret the corrosion rate-temperature dependence, where the Arrhenius behavior gives a geometrical meaning and makes explicit a positive or negative linear dependence of charge transitivity and temperature. In addition, according to the Arrhenius interpretation, it represents the energy that the molecule in the initial state of the process must acquire before it can take part in the reaction, whether it is a physical, or a chemical process. Taking into account the deviation from the linearity, we have extended the Arrhenius-type expression by one term in 1/T2 and we have given some physical meaning to the new related coefficients for which it is found that they depend closely on the number of acid hydrogen atoms in the polyacid for the corrosion and passivation of the Nickel based metallic glass alloy of the composition Ni82.3Cr7Fe3Si4.5B3.2. Moreover, we can consider that the deviation to the Arrhenius linear behavior as a super-Arrhenius behavior In addition, a mathematical analysis of the trend of experimental scatter points of the charge transfer resistance with temperature permits us to reveal an interesting homographic behavior which leads us to suggest an original empirical model with only two optimal adjustable parameters, as well as a new pseudo-power dependence of the number of hydrogen atoms in the polyacid.

“…The decrease in η can be explained in terms of reduced ionic interactions or higher kinetic energy imparted to the liquidus mixture at elevated T. 56 Both of the factors result in the deployment of attractive interactions imparting higher mobility to molecular species within the mixtures. The Arrhenius-like expression is considered to be the most simplistic empirical expression for formulating the relationship between η and T. 57,58 Interestingly, in our systems, the Arrhenius-like expression does not fit the data satisfactorily; instead, the fit to Vogel−Fulcher− Tammann model (VFT model; eq 4) is satisfactory for all the investigated systems over the entire composition range in the temperature regime of 293.15−363.15 K. 59−61 Earlier, the VFT model was found to better correlate η and T for systems constituting small symmetric cations, ILs, and DESs. 62,63 = A B T T ln 0 (4) The strong adherence of η−T of the investigated water-in-(salt + RTILs) electrolytes to the VFT model is depicted in Figure 4, where the curve represents the best fit to the VFT model.…”

The limited solubility of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in water limits the use of aqueous media in Li-ion batteries. Enhancement of LiTFSI solubility in water may be achieved by adding room-temperature ionic liquids (RTILs) to the mixture of Li-salt and water. We present the density (ρ) and dynamic viscosity (η) of ternary electrolytic systems composed of LiTFSI, water, and four different RTILs: 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide [EMIm.TFSI], EMIm trifluoromethanesulfonate [EMIm.OTF], n-butyl-trimethylammonium TFSI [N 4111 .TFSI], and 1-butyl-1-methylpyrrolidinium TFSI [Pyr 14 .TFSI], respectively, over a temperature range of 293.15−363.15 K at different LiTFSI concentrations. The sensitivity of ρ toward T-change is more-or-less constant over the entire composition range. The Tdependence of η is correlated by the Vogel−Fulcher−Tammann model. Linear trends of ρ and η with Li-salt molality were observed for all RTILs except Pyr 14 .TFSI, where a sigmoidal increase better described the data, highlighting the predominant role of the IL cation in determining composition dependence. The extent of increase in ρ and η is much more profound in TFSI − -containing ILs as compared to that in OTf − . We believe that Li + is preferentially solvated by anions of RTIL instead of water molecules, resulting in enhanced solubility and greater ionic interactions. The role of RTIL in achieving favorable results is established nonetheless.

“…26 E a values gradually increase with the increase in the DEA mole fraction, and the monotone change in E a values indicated that the structure of the solvent will change gradually when one component is introduced into another. 75 The ΔH* values are all positive and gradually increase with the increase in x 1 . Usually, the negative ΔS* values indicated that the process of the liquid flow is ordered, and the liquid layer remained continuous, maintaining its internal structure even if it moved in a solid state.…”

Density (ρ) and viscosity (η) values of [diethanolamine (DEA) + alcohols (ethanol, n-propanol, or n-butanol)] ion-like liquids were measured at T = 298.15−318.15 K and atmospheric pressure. Based on these data, the excess molar volume (V m E ), viscosity deviation (Δη), activation Gibbs free energy (ΔG*), excess activation Gibbs free energy of viscous flow (ΔG* E ), apparent molar volume (V φ ), partial molar volume (V̅ ), and thermal expansion coefficient (α p ) of ion-like liquids were calculated. At the same time, the variation of density with various compositions and temperatures was evaluated by the Jouyban−Acree model and nonlinear least squares method. The dependence of viscosity and dynamic viscosity on composition was fitted by the Grunberg−Nissan, Eyring−Margules, Heric, and McAllister equations, and the dependence of viscosity on temperature was fitted by the Arrhenius equation. Meanwhile, the V m E , Δη, and ΔG* E of ion-like liquids were fitted by the Redlich−Kister (R−K) equation. The intermolecular hydrogen bond (IHB) was discussed in depth on the basis of the change of ultraviolet (UV) and Raman spectra. To further prove the IHBs and their interaction forms, the monomolecular and bimolecular stable structures of DEA with alcohols were optimized by density functional theory (DFT), and the weak interactions between molecules were discussed in depth.
