“…According to Figure 5d, both anodic (zinc dissolution) and cathodic (zinc precipitation) reactions are inhibited after the addition of PG, and the inhibition efficiency increases with PG% (64.10% and 97.01% for 10% PG and 50% PG electrolytes, respectively), suggesting that the PG molecules adsorb on the metal surface and block the active sites. [ 46,47 ] Even though this result does not directly reveal the self‐organization mediated solid‐like PG film formation at low concentrations, it can be argued that at high surface coverage of PG steric crowding and repulsive interactions would lead to the breakdown of self‐organization, as observed from simulations. Thus, the experimental observations corroborate the simulation‐derived hypothesis of the unique concentration‐dependent behavior of PG, but a more in‐depth multi‐component simulation is necessary to unravel a comprehensive understanding of the underlying physicochemical phenomena, which would be considered in the future.…”

Inexpensive and energy-dense Zn metal anodes is key to the promise of aqueous Zn-ion batteries, which are heralded as an exciting battery chemistry for renewable and stationary storage. Yet, Zn deposition instability under demanding cycling conditions leads to rapid dendritic cell failure, and the hydrogen evolution reaction aggravates the issue. Electrolyte additives are a scalable solution to address the problem, but a high volume fraction is typically required for a noticeable effect. Here, a benign alcohol molecule propylene glycol is presented as an electrolyte additive that enables remarkably stable Zn anode cycling of over 1000 h at a practical 2 mA-2 mA h cm −2 at a low volume concentration when the reference cell shorts only after 30 h. The dramatic performance improvement at the low additive concentration is attributed to the effective morphology regulation and inhibition of hydrogen evolution, as revealed by spectroscopic and microscopic investigations. Ab initio molecular dynamics simulations reveal unprecedented atomistic insights behind the concentration-dependent effectivity of propylene glycol as an electrolyte additive. Excellent full cell cycling with two different positive host materials, even with high loading, highlights the potential for practical development.

“…The impedance data indicate one capacitive arc and one inductive arc at highfrequency values and at low-frequency values which shows two time constants, respectively. The existence of the inductive arc in low frequencies may be ascribed to the relaxation procedure achieved using adsorption species such as Hads + and Cladson the surface of X80 steel [39][40][41][42]. Moreover, it may be ascribed to the passivated surface re-dissolution at low frequency values [42].…”

Different theoretical, electrochemical and surface techniques were applied to study the corrosion inhibition effects of 2-Amino-6-hydroxybenzothiazole in 5% HCl solution. The density functional theory was carried out and quantum chemical factors like the energy gap, energy of highest occupied molecular orbital, the energy of lowest unoccupied molecular orbital, the fraction of electron transferred, and Mulliken charges have been calculated. In addition, according to quantum calculation, S atom in 2-Amino-6-hydroxybenzothiazole indicated more tendency for electrophilic attack in adsorption. The main reason for high inhibition efficiencies in very low concentrations is the planar and simplicity of inhibitor structure which leads to increasing the efficiency of adsorption by functional group especially sulfur. Electrochemical frequency modulation and potentiodynamic polarization indicated that this material has excellent inhibiting features in very low concentrations. The influence of DC trend on the explanation of electrochemical noise data was evaluated by polynomial fitting and the optimum polynomial order m=4 was obtained. Noise resistance and the inhibition efficiency was calculated and compared in different methods. The theory of shot noise in frequency domain was used to obtain the electrochemical event charge. The corroded surface of steel in the absence and existence of thiazole compound was studied by Atomic force microscopy.

Electrochemical noise signals in many cases exhibit a DC drift that should be removed prior to further data analysis. Polynomial fitting and moving average removal method have been used to remove trends of electrochemical noise (EN) in time domain. The corrosion inhibition of synthesized schiff base N,N′-bis(3,5-dihydroxyacetophenone)-2,2-dimethylpropandiimine on API-5L-X70 steel in hydrochloric acid solutions were used to study the effects of drifts removal methods on noise resistance calculation. Also, electrochemical impedance spectroscopy (EIS) was used to study the corrosion inhibition property of the inhibitor. The results showed that for the calculation of R n , both methods were effective in trend removal and the polynomial with m=4 and MAR with p=40 were in agreement.
