“…The decrease of values of solution may be attributed to increase of electrostriction of water molecules from the second solvation layer of the ionic (-COO -/Na + ) groups of sodium valproate drug[43]. Also a close dextrose solution compared to aqueous NaCl.…”

“…It can be observed from Table that cosolute concentration affects the K s,2 ° values. The increase in K s,2 ° with concentration of cosolute and with rising temperature suggests strong solute–solvent (hydrophilic–hydrophilic, hydrophilic-ionic) interactions . The temperature variation of K s,2 ° values (i.e., increment) from Table indicates that interactions between the solute (Th.HCl) and cosolute become favorable.…”

“…The increase in K s,2 °with concentration of cosolute and with rising temperature suggests strong solute− solvent (hydrophilic−hydrophilic, hydrophilic-ionic) interactions. 33 The temperature variation of K s,2 °values (i.e., increment) from Table 5 indicates that interactions between the solute (Th.HCl) and cosolute become favorable. In aqueous solutions, the solute−solvent interaction was more between EAAc and Th.HCl compared to those between the solute and EABu/EAHx PIL solutions.…”

“…In the present study, we investigate the inverted block copolymer system, in which a shorter zwitterionic block PSBP 50 is combined with a much longer non-ionic block PNIPMAM 155 (Figure ) and study the impact of the varied relative block lengths on the swelling characteristics of its thin films in the presence of a monovalent salt, namely KCl. The use of KCl, which alike NaBr belongs to the alkali metal halides, was inspired by biomaterial applications as KCl is commonly used for electrolyte balance regulation. Compared to the previously used salt NaBr, K + is larger than Na + (0.138 nm vs 0.099 nm), and Cl – is smaller than Br – ( 0.181 vs 0.196 nm); however, the difference in the size of the cation and the anion is notably smaller for KCl. Still, solid KCl has the same crystal structure (face-centered cubic) and a similar melting point, while previous studies showed that KCl in the solid state is also partially miscible with polysulfobetaines, though to a lesser extent than NaBr .…”
