To gain insights into the effect of sodium dodecylbenzene sulfonate (SDBS) on Mg corrosion in NaCl medium, in-situ Raman spectroscopy was employed to monitor the interface evolutions of Mg surface in NaCl and NaCl+SDBS solutions. Accompanied by ex-situ Raman, SEM and XPS results, the evolution models during Mg corrosion in corrosive media were established to reveal the influence of DBS − . Competitive adsorption models about the interface of Mg/NaCl+SDBS between DBS − and Cl − were also presented to explain the inhibition effect of SDBS. These models guide the optimal usage of SDBS in Mg alloy corrosion inhibition.

The effects of different dosage of NaCl and sucrose on the structural and functional properties of debranched quinoa starch-oleic acid complexes (DQS-OA) under baking were investigated. The results showed that the resistant starch content of the baked DQS-OA increased by 17.15 % than DQS-OA. The addition of NaCl destroyed the thermal stability, short-range molecular order and crystalline structure of the complexes. The results of particle size, SEM and amylose content showed that NaCl accelerated the degradation of starch granules, which reduced the enzyme resistance of starch. In contrast, the enthalpy (7.28 J/g-7.78 J/g) and crystallinity (54.29 %–56.69 %) of the samples with sucrose significantly increased, and the molecular structure of the complexes became more ordered. Furthermore, with the increase of sucrose concentration, the resistant starch content also increased from 28.80 % to 31.41 %.

Quaternary ammonium based ionic liquids (ILs) are considered as good corrosion inhibitors to protect substrates of metals such as carbon steel, copper and aluminum alloys against corrosion. However, studies applying them to the corrosion protection of magnesium (Mg) alloys still remain scarce. Herein, in this work, three quaternary ammonium based dicationic ILs, namely [DMBAB][MOPS] 2 , [DMBAB][Phe] 2 and [DMBAB][Trp] 2 were synthesized and applied as corrosion inhibitors to improve the corrosion protection ability on AZ91D Mg alloy in 0.5 wt% NaCl solution. Their corrosion inhibition performances were evaluated by electrochemical measurements, and the relevant corrosion results were investigated by extensive characterizations including scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). Results show that the [DMBAB][Trp] 2 obtains an 88.8 % inhibition efficiency for AZ91D Mg alloy in 0.5 wt% NaCl solution, clearly higher than those of [DMBAB][Phe] 2 (80.4 %) and [DMBAB][MOPS] 2 (81.7 %). This suggests that [DMBAB][Trp] 2 presents the best corrosion protection ability on AZ91D Mg alloy among these ILs considered here, which is associated with the largest steric body and the most active adsorption sites of [DMBAB][Trp] 2 in comparison with other two compounds, hence resulting in a highest surface coverage. The present work offers a guidance for understanding the structure–property relationship of quaternary ammonium based dicationic ILs through a convenient, economical and effective way with a promising application in the field of material protection.

An abundance of low-salt sausages had emerged in the market as high salt intake may pose health risks to humans while their limited shelf-life becomes an urgent issue. In this study, tea-polyphenol/β-cyclodextrin/NaCl inclusion complexes (ICs) with thermal stability and better antioxidant activity were successfully prepared, their effects on the quality of low-salt sausages were investigated. The sausages were manufactured with the addition of ICs and NaCl with or without tea-polyphenols respectively, and they were stored at 25 °C for 28 days. IC group exhibited significantly lower oxidation of lipids and protein as the tea-polyphenols in the ICs could exert better antioxidant properties because of the special encapsulation structure. Besides, ICs could inhibit the growth of pathogens preventing the off-flavor. Also, ICs promoted the growth of P. pentosaceus with a strong antioxidant capacity in the sausage model, which maintained the existing pleasant flavor by preventing the oxidation of phenol and alcohol compounds. Meanwhile, ICs also accelerated the growth of Tetragenococcus , which contributed to flavor development at the later stages of fermentation by producing more esters. Hence, it was suggested that ICs could be utilized as a promising salt replacement to improve the quality of traditional Sichuan-style sausages.

Composite chloride salts have become molten salt heat storage materials with high development potential due to their excellent heat storage performance. Since chloride salts are prone to leakage, they need to be adsorbed onto porous materials to prepare composite phase change materials (CPCMs). Changes in the pore size of porous materials will lead to changes in the scale of chloride salts. Currently, there is little research on the impact of scale variation on the thermophysical and phase change characteristics of composite chloride salts, and the underlying mechanisms are not yet clear. With the ZnCl 2 -NaCl-KCl (3:1:1 mol%) eutectic salt as the phase change material (PCM), this study integrates molecular dynamics (MD) simulation with an experimental approach to investigate the impact of scale on the thermophysical properties and phase change properties of CPCM. The inherent influence mechanism of scale effect is analyzed from a microscopic perspective. The results indicate that as the scale increases, the interaction energy between molecules within the system gradually increases, and the system structure becomes more compact. The thermal conductivity first increases and then decreases, reaching a maximum of 0.45 W/(m·K) at 8 nm; the volumetric thermal expansion coefficient gradually decreases. As the scale increases from 3 nm to 15 nm, the melting temperature rises by 8.1 %, while the solidification temperature decreases by 1.73 %, resulting in a significant increase in the degree of supercooling. The latent heat gradually increases with scale, which is consistent with the coordination number.

Transparency has never been integrated into freestanding flexible graphene paper (FF-GP), although FF-GP has been discussed extensively, because a thin transparent graphene sheet will fracture easily when the template or substrate is removed using traditional methods. Here, transparent FF-GP (FFT-GP) was developed using NaCl as the template and was applied in transparent and stretchable supercapacitors. The capacitance was improved by nearly 1000-fold compared with that of the laminated or wrinkled chemical vapor deposition graphene-film-based supercapacitors.

The inhibition effect of 4,6-diamino-2-mercaptopyrimidine (DAMP) as a copper corrosion inhibitor in 3.5 wt% NaCl solution was investigated by weight loss, electrochemical impedance spectroscopy, and potentiodynamic polarization. The inhibition efficiency increased with increasing DAMP concentration in the range of 1.0 to 2.0 mM DAMP and decreased with increasing temperature. The obtained results showed that DAMP inhibited both the anodic and cathodic currents and the maximum inhibition efficiency reached 93.2% at 2.0 mM DAMP. The inhibition performance of DAMP was confirmed by SEM and EDS. Quantum chemical calculations revealed that the DAMP molecule was adsorbed on the copper surface in a paralleled way through S and N atoms and the pyrimidine ring. Adsorption of DAMP was found to obey the Langmuir adsorption isotherm.

Scrap aluminum (Al) alloy recycling is critical for energy conservation and decreasing carbon emissions. Conventional remelting process does not remove alloying elements, severely limiting the value and applications of recycled Al. To overcome this limitation, this study develops an efficient process for recovering pure Al from scrap Al alloys via soluble anode electrolysis in a designed MgCl 2 -KCl-NaCl (MKN) molten salt system. Real-time monitoring of the electrolysis process, time-dependent characterization of cathodic deposits, and electrochemical analyses reveal a three-stage cathodic deposition mechanism in the MKN molten salt system: initial underpotential deposition of Mg 2+ transitions to co-deposition of Mg 2+ and Al 3+ , and ultimately to exclusive reduction of Al 3+ , which is driven by progressive Al 3+ accumulation. The introduction of AlCl 3 proves pivotal, simultaneously enhancing Al 3+ deposition efficiency while effectively suppressing Mg 2+ co-reduction. Systematic optimization identifies 12.5 wt% AlCl 3 addition, 500 °C, and 0.15 A/cm 2 as the ideal operational parameters, achieving recycled Al with 99.84 wt% purity. The soluble anode electrolysis process in the MKN molten salt system represents an efficient and scalable alternative to conventional remelting. The developed process is capable of producing recycled Al with purity comparable to that of primary Al while addressing critical sustainability challenges in the Al industry.

Li ion capacitors (LICs) are emerging as a promising device to integrate the high power density of supercapacitors with the high energy density of Li ion batteries. However, the insufficient specific capacity of the conventional capacitive electrode presents a great challenge in achieving high energy density for LICs. Herein, we demonstrate the synthesis of hierarchical porous carbon with an extremely large specific surface area of 3898 m2 g−1 and an improved graphitization degree by using egg white biomass as a precursor and NaCl as a template, in which dual functional NaCl served both as a macropore creating template and a graphitic catalyst to enhance the graphitization degree. With rational design, the developed porous carbon exhibits a noticeably enhanced specific capacity of 118.8 mA h g−1 at 0.1 A g−1 with excellent rate capability and improved cycling stability over 4000 cycles in an organic Li ion conducting electrolyte. Furthermore, the obtained porous carbon was employed as a cathode paired with a Fe3O4@C anode for LIC applications, which delivers an integrated high energy density of 124.7 W h kg−1 and a power density of 16 984 W kg−1 as well as a superior capacity retention of 88.3% after 2000 cycles at 5 A g−1, demonstrating the promising application as potential electrode candidates for efficient energy storage systems.

Due to its low energy consumption, capacitive deionization (CDI) is regarded as one of the most promising technologies in brackish water desalination. However, CDI has two drawbacks, namely, low deionization capacity and unavoidable parasitic reactions that limit its further development. Unlike the traditional CDI electrodes that store the ions in the electric double layer capacitors, faradic electrodes store ions at crystallographic sites or between the atomic planes, which could effectively address the issues mentioned above. However, obtaining low-cost faradic electrode materials with a high salt removal capacity for practical applications is still challenging. Here, we report a new material, mesoporous amorphous FePO 4 nanosphere@Graphene (FePO 4 @RGO) synthesized via a one-step hydrothermal method. Electrochemical experiments demonstrate that the formation of a mesoporous structure and covered by graphene can address the drawbacks of pure FePO 4 for electroconductivity and ion diffusion rates. When used in desalination, the novel design enhances the desalination capacity, and the rates increase by 60% (50.13–85.94 mg/g) and 180% (0.079–0.24 mg/g/s), respectively, while energy consumption decreases by 25%. The production cost of the material was calculated, and implies that this material has potential for use in large-scale desalination.

The solid–liquid phase equilibria of the Li+, Na+, Ca2+//Cl––H2O quaternary system at 298.15 and 323.15 K are studied via the isothermal solubility phase equilibrium method. The solubility data and liquid properties of density and pH are obtained. The phase diagrams of the quaternary systems, including the water free diagram, the water diagram, and the dry salt diagram, are plotted to show the phase regions, water content, and salting-in effect. NaCl occupies the largest phase region at both 298.15 and 323.15 K. One double salt LiCl·CaCl2·5H2O occurs at 298.15 K and builds up two invariant points; one incommensurate invariant point saturated by (NaCl, LiCl·H2O, LiCl·CaCl2·5H2O) and one commensurate invariant point saturated by (NaCl, CaCl2·4H2O, LiCl·CaCl2·5H2O), but at 323.15 K, no double salt forms. The salting-in effect that happened in ternary systems still occurs in the quaternary Li+, Na+, Ca2+// Cl––H2O system at both temperatures. NaCl saturated concentration increases with LiCl and CaCl2 contents and results in a very high total salt content at commensurate invariant points, e.g., they are 56.92 and 60.62% at 298.15 and 323.15 K, respectively.

We investigate the effect of ultrasound on the evaporation and crystallization of sessile NaCl solution droplets which were positioned in traveling or standing wave ultrasound field. The experimental results indicated that the ultrasound field can significantly accelerate the evaporation rate of the sessile droplets and refine the crystal grains. By adjusting the distance between the sessile droplets and the ultrasound emitter, it is found that, in traveling wave ultrasound field, the sessile droplet evaporation time and the time for the appearance of NaCl grains exhibited a fluctuating increase as the droplet-emitter distance increased. While in the standing wave ultrasound, the sessile droplet evaporation rate increases with the increasing droplet-emitter distance. Overall, the traveling wave ultrasound field has a stronger effect on grain refinement of the sessile droplets than the standing wave ultrasound field. The grain refinement is attributed to the decrease of critical nucleation radius caused by ultrasound energy and the increase of the nucleation rate caused by the accelerated evaporation rate. In addition, the breakage of grains caused by ultrasonic cavitation would also lead to grain refinement.
