Sarkar, Pulak; Modak, Solagna; Karan, Santanu published an article in 2021. The article was titled 《Ultraselective and Highly Permeable Polyamide Nanofilms for Ionic and Molecular Nanofiltration》, and you may find the article in Advanced Functional Materials.Electric Literature of ClNa The information in the text is summarized as follows:

Membranes with ultrahigh ion selectivity and high liquid permeance are needed to produce high-quality product water with increased recovery and process efficiency in water desalination. The narrow pore size distribution and controlled surface charge in the separation layer of nanofiltration membranes significantly improve the ion selectivity through mol. sieving and Donnan exclusion of co-ions. Here, the ultraselective and yet highly water permeable polyamide nanofilm composite nanofiltration membranes developed by precisely controlling the kinetics of the interfacial polymerization reaction by maintaining the stoichiometric equilibrium at the interface is reported. The kinetically favorable stoichiometric equilibrium condition prohibits the formation of aggregate pores in the nanofilm and leads to the formation of narrow network pores with a high surface neg. charge. Nanofilms are designed with a controlled degree of crosslinking and made as thin as ≈7 nm to achieve increased water permeance. The ultraselective membranes exhibit up to 99.99% rejection of divalent salt (Na2SO4) and demonstrate monovalent to divalent ion selectivity of >4000. The selectivity of these nanofilm composite membranes is beyond the permeance-selectivity upper-bound line of the state-of-the-art nanofiltration membranes and one to two orders of magnitude higher than the com. available membranes with pure water permeances of up to 23 L m-2 h-1 bar-1. The fabrication process is scalable for membrane manufacturing The experimental process involved the reaction of Sodium chloride(cas: 7647-14-5Electric Literature of ClNa)

Sodium chloride(cas: 7647-14-5) has been used for the preparation of tris buffered saline, phosphate buffered saline, MPM-2 (mitotic protein monoclonal 2) cell lysis buffer, immunoprecipitation wash buffer, LB (Luria-Bertani) media and dialysis buffer.Electric Literature of ClNa

《Rates of alkaline hydrolysis of meta-and para-substituted ethyl β-phenylpropionates and correlation with σ0》 was published in Journal of Organic Chemistry in 1966. These research results belong to Fuchs, Richard; Caputo, Joseph A.. Product Details of 7116-36-1 The article mentions the following:

A series of 20 meta-and para-substituted Et β-phenylpropionates were prepared, and the rates of alk. hydrolysis in 87.8% ethanol at 30° measured. The rates generally follow the σ0 values for the substituents estimated from other reactivities and from F19 N.M.R. shielding in similar solvents. The unexpectedly high rate of the m-Me3N+ compound may be due to a direct, short-range electrostatic interaction in the transition state for hydroxide ion attack of the ester.
