“…The higher values obtained for glycine/ l -alanine in water indicate that strong solute–solvent interactions exist between glycine/ l -alanine and water. In fact, strong interactions of the three carboxyl groups and one hydroxyl group of CA with water via hydrogen bonds leads to the higher values, however the hydrophobic group in SA [ 23 ] reduces its ability to form strong hydrogen bonds with water, thus resulting in smaller values (Fig. 7 a).…”

“…The values of glycine/ l -alanine in water agree well with the literature values at different temperatures and are shown in Figs. 8 and 9 [ 8 , 23 , 26 – 28 , 30 , 35 , 36 ]. Table 3 shows that the values are higher for l -alanine in water and in aqueous CA solutions compared to glycine, as expected, which is due to the increase in the molar mass of l -alanine.…”

Apparent molar volumes of glycine/l-alanine in water and in aqueous citric acid (CA) solutions of varying concentrations, i.e. (0.05, 0.10, 0.20, 0.30, 0.40 and 0.50) mol·kg−1 were determined from density measurements at temperatures T = (288.15, 298.15, 308.15, 310.15 and 318.15) K and at atmospheric pressure. Limiting partial molar volumes and their corresponding partial molar volumes of transfer have been calculated from the data. The negative values obtained for glycine/l-alanine from water to aqueous CA solutions indicate the dominance of hydrophilic–hydrophobic/hydrophobic–hydrophilic and hydrophobic–hydrophobic interactions over ion/hydrophilic–dipolar interactions. Further, pair and triplet interaction coefficients, i.e. along with hydration number have also been calculated. The effect of temperature on the volumetric properties of glycine/l-alanine in water and in aqueous CA solutions has been determined from the limiting partial molar expansibilities and their second-order derivative . The apparent specific volumes for glycine and l-alanine tend to approach sweet taste behavior both in the presence of water and in aqueous CA solutions. The values for glycine/l-alanine increase with increase in concentration of CA at all temperatures studied. This reveals that CA helps in enhancing the sweet taste behavior of glycine/l-alanine which also supports the dominance of hydrophobic–hydrophobic interactions.Electronic supplementary materialThe online version of this article (10.1007/s10953-018-0829-6) contains supplementary material, which is available to authorized users.

Aqueous zinc ion batteries hold promise as alternative systems to lithium‐based batteries. However, practical development faces critical challenges due to parasitic side reactions and dendrite growth in zinc anodes. While introducing electrolyte additives is promising, monofunctional additives offer limited protection to the zinc anode from a single aspect. Herein, a disodium succinate additive is presented to establish a hydrophobic and zincophilic dual electric layer structure on the Zn surface, regulate the solvation structure of Zn2+, and act as a pH buffer during cycling. As a result, the symmetrical cell with an electrolyte containing 0.2 m SADS shows a durable life of over 2200 h, and the Zn||MnO2 full cell still maintains an 80% capacity retention after 1000 cycles. In addition, SADS both show wide applicability in the match with NVO and I2 cathode. This work provides a low‐cost and multifunctional electrolyte additive, facilitating the development of high‐performance aqueous zinc ion batteries.
