In 2019,Journal of Chemical Physics included an article by Jiang, Hao; Debenedetti, Pablo G.; Panagiotopoulos, Athanassios Z.. Computed Properties of ClNa. The article was titled 《Nucleation in aqueous NaCl solutions shifts from 1-step to 2-step mechanism on crossing the spinodal》. The information in the text is summarized as follows:

In this work, we use large-scale mol. dynamics simulations coupled to free energy calculations to identify for the first time a limit of stability (spinodal) and a change in the nucleation mechanism in aqueous NaCl solutions This is a system of considerable atm., geol., and tech. significance. We find that the supersaturated metastable NaCl solution reaches its limit of stability at sufficiently high salt concentrations, as indicated by the composition dependence of the salt chem. potential, indicating the transition to a phase separation by spinodal decomposition However, the metastability limit of the NaCl solution does not correspond to spinodal decomposition with respect to crystallization We find that beyond this spinodal, a liquid/amorphous separation occurs in the aqueous solution, whereby the ions first form disordered clusters. We term these clusters as “”amorphous salt.””. We also identify a transition from one- to two-step crystallization mechanism driven by a spinodal. In particular, crystallization from aqueous NaCl solution beyond the spinodal is a two-step process, in which the ions first phase-sep. into disordered amorphous salt clusters, followed by the crystallization of ions in the amorphous salt phase. By contrast, in the aqueous NaCl solution at concentrations lower than the spinodal, crystallization occurs via a one-step process as the ions aggregate directly into crystalline nuclei. The change of mechanism with increasing supersaturation underscores the importance of an accurate determination of the driving force for phase separation The study has broader implications on the mechanism for nucleation of crystals from solutions at high supersaturations.

《High permeability sub-nanometre sieve composite MoS2 membranes》 was written by Sapkota, Bedanga; Liang, Wentao; VahidMohammadi, Armin; Karnik, Rohit; Noy, Aleksandr; Wanunu, Meni. Name: Sodium chloride And the article was included in Nature Communications in 2020. The article conveys some information:

Two-dimensional membranes have gained enormous interest due to their potential to deliver precision filtration of species with performance that can challenge current desalination membrane platforms. Molybdenum disulfide (MoS2) laminar membranes have recently demonstrated superior stability in aqueous environment to their extensively-studied analogs graphene-based membranes; however, challenges such as low ion rejection for high salinity water, low water flux, and low stability over time delay their potential adoption as a viable technol. Here, we report composite laminate multilayer MoS2 membranes with stacked heterodimensional one- to two-layer-thick porous nanosheets and nanodisks. These membranes have a multimodal porous network structure with tunable surface charge, pore size, and interlayer spacing. In forward osmosis, our membranes reject more than 99% of salts at high salinities and, in reverse osmosis, small-mol. organic dyes and salts are efficiently filtered. Finally, our membranes stably operate for over a month, implying their potential for use in com. water purification applications.

The article was titled 《Design, synthesis and evaluation of metronidazole-1,2,3-triazole derivatives as potent urease inhibitors》.Formula: C7H6BrCl The article contains the following contents:

A new series of benzyl-(imidazolylmethyl)triazole derivatives I [R = H, 2-Me, 4-Br, etc.] was synthesized and evaluated as Helicobacter pylori urease inhibitors. All the synthesized compounds were more potent than standard inhibitor thiourea against urease. Among the synthesized compounds, compound I [R = 4-F] (IC50 = 1.975 ± 0.25μM) with inhibitory activity around 11-fols more than thiourea (IC50 = 22.00 ± 0.14μM) was the most potent compound Kinetic study of this compound revealed that compound I [R = 4-F] inhibited urease in an uncompetitive mode. Based on mol. modeling study, compound I [R = 4-F] pointed toward the bi-nickel center and stabilized by H-bond and T-shape π-π hydrophobic interactions with the critical residues His492 and Asp633. Moreover, it anchored to the helix-turn-helix motif in the active site cavity through interaction with His593 and Arg609. Consequently, it proposed that compound I [R = 4-F] through stabilization of active site flap inhibited urease activity.

Blanco, Christian O.; Nascimento, Daniel L.; Fogg, Deryn E. published their research in Organometallics in 2021. The article was titled 《Routes to High-Performing Ruthenium-Iodide Catalysts for Olefin Metathesis: Ligand Lability Is Key to Efficient Halide Exchange》.Related Products of 172222-30-9 The article contains the following contents:

Clean, high-yielding routes are described to Ru-diiodide catalysts that were recently shown to enable high productivity in olefin metathesis. For the 2nd-generation Grubbs and Hoveyda catalysts (GII: RuCl2(H2IMes)(PCy3)(:CHPh); HII: RuCl2(H2IMes)(:CHAr), Ar = C6H4-2-OiPr), slow salt metathesis is shown to arise from the low lability of the ancillary PCy3 or ether ligands, which retards access to the four-coordinate intermediate required for efficient halide exchange. To exploit the lability of the 1st-generation catalysts, the diiodide complex RuI2(PCy3)(:CHAr) HI-I2 was prepared by treating Grubbs I (RuCl2(PCy3)2(:CHPh), GI) with NaI, H2C:CHAr (1a), and a phosphine-scavenging Merrifield iodide (MF-I) resin. Subsequent installation of H2IMes or cyclic (alkyl)(amino)carbene (CAAC) ligands afforded the 2nd-generation iodide catalysts in good to excellent yields. Given the incompatibility of the nitro group with a free carbene, the iodo-Grela catalyst RuI2(H2IMes)(:CHAr’) (nG-I2: Ar’ = C6H3-2-OiPr-4-NO2) was instead accessed by sequential salt metathesis of GI with NaI, installation of H2IMes, and finally cross-metathesis with the nitrostyrenyl ether H2C:CHAr’ (1b), with MF-I as the phosphine scavenger. The bulky iodide ligands improve the selectivity for macrocyclization in ring-closing metathesis. In the experiment, the researchers used Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Related Products of 172222-30-9)

Addnl., a formal β-selective alkene alkoxycarbonylation is developed. Moreover, a variety of oxindole-3-acetates I (R2 = H, t-Bu, CN, me, etc.; R3 = Me, Bn; R4 = Me, Et, Bn, i-Pr), Et 2-(1-methyl-2-oxo-1,2,5,6-tetrahydro-4H-pyrrolo[3,2,1-ij]quinolin-1-yl)acetate, Et 2-(7-methyl-6-oxo-1,2,3,4,6,7-hexahydroazepino[3,2,1-hi]indol-7-yl)acetate, Et 2-(1,3-dimethyl-2-oxo-2,3-dihydro-1H-benzo[g]indol-3-yl)acetate and furoindolines II are prepared in good to excellent yields.
