《Corrosion protection mechanism of Ce4+/organic inhibitor for AA2024 in 3.5% NaCl》 was published in RSC Advances in 2020. These research results belong to Gobara, Mohamed; Baraka, Ahmad; Akid, Robert; Zorainy, Mahmoud. Name: Sodium chloride The article mentions the following:

Cerium is a rare earth element that has been widely proposed for the corrosion protection of aluminum alloys (AA). Both cerium salts, Ce3+ and Ce4+, have been used in combination with other compounds to offer synergistic inhibition, however, the inhibitive corrosion mechanism when using Ce4+ with organic compounds is still not clear. In this study, the synergistic inhibition effect of Ce4+ and melamine (M) on the corrosion of aluminum alloy 2024 (AA2024) in 3.5% NaCl solution was investigated. Potentiodynamic Polarization (PDP) and Electrochem. Impedance Spectroscopy (EIS) techniques were used to study the synergistic effect of different Ce4+/M ratios on the corrosion behavior of AA2024. The PDP study showed that a combination of 50% Ce4+ and 50% M leads to the lowest corrosion rates, both acting as cathodic inhibitors. Both PDP and EIS results indicated that M or Ce4+ in isolation did not offer effective corrosion protection, while the combination of M and Ce4+ significantly enhances the corrosion protection with a synergism parameter equal to 3.5. SEM and EDX observations confirm the findings from the electrochem. techniques. A new mechanism of corrosion synergistic inhibition by Ce4+ and organic compounds is postulated where the role of the organic compounds is to enhance the reduction of Ce4+. In the experiment, the researchers used many compounds, for example, Sodium chloride(cas: 7647-14-5Name: Sodium chloride)

Activated carbon is the most common electrode material used in electrosorption processes such as water desalination with capacitive deionization (CDI). In the present work, we study ion selectivity from salt mixtures with two different monovalent ions, chloride and nitrate. We run adsorption experiment in microporous carbons (i.e., without applying a voltage), as well as electrosorption experiments (i.e., based on applying a voltage between two carbon electrodes). Our results show that i. during adsorption and electrosorption, activated carbon removes much more nitrate than chloride; ii. at equilibrium, ion selectivity does not depend strongly on the composition of the water, but does depend on charging voltage in CDI; and iii. during electrosorption, ion selectivity is time-dependent. We modify the amphoteric Donnan model by including an addnl. affinity of nitrate to carbon. We find good agreement between our exptl. results and the theory. Despite this decrease, the affinity-effect for nitrate continues to play an important role also at a high voltage. In general, we can conclude that our work provides new insights in the importance of carbon-ion interactions for electrochem. water desalination.

Excess dietary salt contributes to inflammation and hypertension via poorly understood mechanisms. Antigen presenting cells including dendritic cells (DCs) play a key role in regulating intestinal immune homeostasis in part by surveying the gut epithelial surface for pathogens. Previously, we found that highly reactive γ-ketoaldehydes or isolevuglandins (IsoLGs) accumulate in DCs and act as neoantigens, promoting an autoimmune-like state and hypertension. We hypothesized that excess dietary salt alters the gut microbiome leading to hypertension and this is associated with increased immunogenic IsoLG-adduct formation in myeloid antigen presenting cells. To test this hypothesis, we performed fecal microbiome analysis and measured blood pressure of healthy human volunteers with salt intake above or below the American Heart Association recommendations. We also performed 16S rRNA analysis on cecal samples of mice fed normal or high salt diets. In humans and mice, high salt intake was associated with changes in the gut microbiome reflecting an increase in Firmicutes, Proteobacteria and genus Prevotella bacteria. These alterations were associated with higher blood pressure in humans and predisposed mice to vascular inflammation and hypertension in response to a sub-pressor dose of angiotensin II. Mice fed a high salt diet exhibited increased intestinal inflammation including the mesenteric arterial arcade and aorta, with a marked increase in the B7 ligand CD86 and formation of IsoLG-protein adducts in CD11c+ myeloid cells. Adoptive transfer of fecal material from conventionally housed high salt-fed mice to germ-free mice predisposed them to increased intestinal inflammation and hypertension. These findings provide novel insight into the mechanisms underlying inflammation and hypertension associated with excess dietary salt and may lead to interventions targeting the microbiome to prevent and treat this important disease.

And the article was published in Biomolecules in 2019. Application In Synthesis of Sodium chloride The author mentioned the following in the article:

Ca2+ serves as a ubiquitous second messenger regulating several aspects of plant growth and development. A group of unique calcium sensor proteins, calcineurin B-like (CBL), interact with CBL-interacting protein kinases (CIPKs) to decode the Ca2+ signature inside the cell. Although CBL-CIPK signaling toolkit has been shown to play significant roles in the responses to numerous stresses in different plants, the information about pineapple CBL-CIPK remains obscure. In the present study, a total of eight AcCBL and 21 AcCIPK genes were identified genome-wide in pineapple. The identified genes were renamed on the basis of gene ID in ascending order and phylogenetic anal. divided into five groups. Transcriptomic data anal. showed that AcCBL and AcCIPK genes were expressed differentially in different tissues. Further, the expression anal. of AcCBL1 in different tissues showed significant changes under various abiotic stimuli. Addnl., the ectopic expression of AcCBL1 in Arabidopsis resulted in enhanced tolerance to salinity, osmotic, and fungal stress. The present study revealed the crucial contribution of the CBL-CIPK gene in various biol. and physiol. processes in pineapple.Sodium chloride(cas: 7647-14-5Application In Synthesis of Sodium chloride) was used in this study.

Different from the traditional two-electron oxidative addition-transmetalation-reductive elimination coupling strategy, visible light has been successfully integrated into transition metal-catalyzed coupling reaction of propargylic alc. derivatives e.g., 1-ethynylcyclohexyl Me oxalate highly selectively forming allenenitriles e.g., 3-cyclohexylideneprop-2-enenitrile specifically speaking, visible light-mediated Cu-catalyzed cyanation of propargylic oxalates has been realized for the general, efficient, and exclusive syntheses of di-, tri, and tetra-substituted allenenitriles bearing various synthetically versatile functional groups.

《Minimal and zero liquid discharge with reverse osmosis using low-salt-rejection membranes》 was written by Wang, Zhangxin; Deshmukh, Akshay; Du, Yuhao; Elimelech, Menachem. Computed Properties of ClNa And the article was included in Water Research in 2020. The article conveys some information:

Minimal and zero liquid discharge (MLD/ZLD) are wastewater management strategies that are attracting heightened attention worldwide. While conventional reverse osmosis (RO) has been proposed as a promising technol. in desalination and MLD/ZLD processes, its application is limited by the maximum hydraulic pressures that current RO membranes and modules can withstand. In this study, we develop low-salt-rejection RO (LSRRO), a novel staged RO process, that employs low-salt-rejection membranes to desalinate or concentrate highly saline feed streams, requiring only moderate hydraulic pressures. Based on process modeling, we demonstrate that LSRRO can overcome the hydraulic pressure limitations of conventional RO, achieving hypersaline brine salinities (>4.0 M NaCl or 234 g L-1 NaCl) that are required for MLD/ZLD applications, without using excessively high hydraulic pressures (≤70 bar). In addition, we show that the energy efficiency of LSSRO is substantially higher than traditional thermally-driven phase-change-based technologies, such as mech. vapor compressor (MVC). For example, to concentrate a saline feed stream from 0.1 to 1.0 M NaCl, the specific energy consumption (SEC) of 4-stage LSRRO ranges from 2.4 to 8.0 kWh of elec. energy per m3 of feedwater treated, around four times less than that of MVC, which requires 20-25 kWhe m-3. Furthermore, compared to osmotically mediated RO technologies that require bilateral countercurrent stages to treat hypersaline brines, LSRRO is eminently more practical as it can be readily implemented by using ‘loose’ RO or nanofiltration membranes in conventional RO. Our study highlights LSRRO’s potential for energy efficient brine concentration using moderate hydraulic pressures, which would drastically improve the energetic and economic performance of MLD/ZLD processes.
