This study investigated the substitution of NaCl with MgCl 2 or CaCl 2 in κ/ι-car myofibrillar protein complexes (K/I-MP) to improve low-sodium gel meat products. Texture and cooking loss analysis showed that the effects of MgCl 2 or CaCl 2 depended on the carrageenan type and conditions. κ-carrageenan (κ-car ) exhibited a negative effect under Ca 2+ (cooking loss increased by 30.69%) and a positive effect under Mg 2+ (cooking loss decreased by 13.41%); both carrageenans showed regulatory effects, with κ-car having a greater impact. Analysis of hydrophobicity, sulfhydryl content, particle size, AFM, CD, rheology, infrared spectroscopy, and molecular docking revealed that Ca 2+ and ι-carrageenan (ι-car) formed complexes via salt bridges, significantly enhancing MP aggregation and structural stability. Infrared spectroscopy and molecular docking further confirmed that ι-car reacted more readily with MP than κ-car Particle size increased from 1.5 μm to 2.5 μm, α-helix content rose from 25% to 35%, and hydrophobic group exposure decreased. In contrast, κ-car promoted aggregation through hydrophobic interactions and sulfhydryl crosslinking, with a weaker increase in α-helix content (25% to 28%). Mg 2+ had a weaker effect but significantly enhanced aggregation when combined with κ-car. In conclusion, Ca 2+ enhanced MP structure via salt bridges, especially with ι-car, while κ-car promoted aggregation by altering protein conformation. Mg 2+ had a weaker effect but enhanced aggregation with κ-car. These findings provide new insights into the synergy between divalent cations and carrageenan in MP gelation and strategies for developing low-sodium meat products.

The complex ions in NaCl-KCl-Al2S3 molten salts at temperatures of 923–1003 K were investigated via Raman spectroscopy and quantum chemistry calculations. The results showed the presence of Al2S3Cl–, AlSCl32–, and AlSCl2– in the molten salts. Besides that, there are two types of dissolution reactions for Al2S3: one is the reaction with Cl–, generating AlSCl32– and AlSCl2–, and the other is the reaction with Cl–, forming Al2S3Cl–. Once the temperature increases, the reaction between Al2S3Cl– and Cl– occurs, promoting the formation of AlSCl32– and AlSCl2–. Meanwhile, the reaction between AlSCl2– and Cl– occurs with the formation of AlSCl32–. With the increase in Al2S3 content, Al2S3 participates in the reaction with Cl–, producing Al2S3Cl–, which also leads to the formation of AlSCl2– and AlSCl32–. Meanwhile, the reaction of Al2S3Cl– with Cl– results in the generation of AlSCl32– and AlSCl2–. The non-bridging S atom in Al2S3Cl– and the S atoms in AlSCl32– and AlSCl2– are the easiest to be attacked by electrophilic molecules. In turn, the Al atom bonded to one Cl atom and two S atoms in Al2S3Cl– and the Al atoms in AlSCl32– and AlSCl2– are the primary sites reacting with nucleophilic molecules.

N and S co-doped carbon dots (N, S-CDs) were synthesized and used as corrosion inhibitors for the first time in this study. The inhibition performance of N, S-CDs for carbon steel in CO 2 -saturated NaCl solution was investigated. Results showed that N, S-CDs can effectively protect carbon steel from corrosion and the inhibition efficiency increases as the concentration of N, S-CDs increases, reaching 93% at 50 mg/L. Even at the low concentration, such as 10 mg/L N, S-CDs, the corrosion current density reduces from 1.472 × 10 −4 A·cm −2 in the blank condition to 2.99 × 10 −5 A·cm −2 after 12 h immersion. N, S-CDs can adsorb on carbon steel through their functional groups and nanoparticles made up of N, S-CDs can form a hydrophobic film on the metal surface, whose thickness was about 40 nm. A theoretical model is established to describe the inhibition mechanism of N, S-CDs.

Drilling fluid systems with exceptional performance serve as a foundation for commercial hydrate extraction. However, most hydrate reservoirs are located at relatively deep water depths and have shallow burial depths. As a result, there are high demands on the density of a hydrate drilling fluid system. Thus, the traditional hydrate drilling fluid system no longer meet the drilling needs in deep water shallow hydrate reservoirs. In this paper, a copolymer SYZ-2 was synthesized based on N-Vinyl-ε-caprolactam and N, N-dimethyl acrylamide. The effects of SYZ-2 and its NaCl system on methane hydrate were first tested by a constant rate cooling method, and the inhibition mechanisms of the system on hydrate nucleation and formation were investigated by molecular simulations. Meanwhile, the formulation and properties of a low-density hydrate drilling fluid system (1.06 g/cm 3 ) based on SYZ-2 were also described in detail. The experimental results show that the hydrate formation temperature with the influence of SYZ-2 decreases from 10.6 °C to 2.7 °C, which can even be significantly reduced to −3.1 °C in the presence of 7 % NaCl. The molecular dynamic simulation results show that SYZ-2 inhibits the nucleation of hydrates by decreasing the solubility of methane molecules, primarily by promoting the agglomeration of methane molecules. Additionally, SYZ-2 can also adsorb to the surface of hydrates and prevent the hydrate cage structure from capturing methane molecules. In contrast, NaCl inhibits hydrates formation by restricting the movement of water molecules. These results provide valuable insights into a better understanding of the gas hydrate inhibition mechanisms, the rational development of high-performance hydrate inhibitors for drilling fluids, as well as the construction of drilling fluid systems.

Iron coordinated with nitrogen (FeN x ) sites hosted in the micropores of carbon substrate offer excellent performance for the oxygen reduction reaction (ORR). Achieving a highly exposed and dispersed FeN x sites accessible for ORR is still challenging to date. In this work, two-dimensional hexagonal carbon nanosheets supported FeN x moieties (FeNC-NaCl- T ) were synthesized via a molten NaCl-assisted pyrolysis strategy. Benefit from the high specific surface area (1371.635 m 3 ·g −1 ) and highly dispersed FeN x sites, the optimized FeNC-NaCl-900 exhibits superior ORR activity with a high half-wave potential of 0.90 V in alkaline electrolyte. Impressively, with FeNC-NaCl-900 as the cathode catalyst in aqueous zinc–air battery, achieving a remarkable performance with a high peak power density of 177 mW·cm −2 and competitive durability (200 h). Furthermore, the Al-air battery equipped with FeNC-NaCl-900 attained an ultrahigh specific capacity of 2257.48 mAh·g −1 at a large discharge current of 100 mA cm −2 . These findings provide guidance for the development of high performance FeNC catalysts and their applications in metal-air batteries.

The effect of NaCl (0.1 − 3.0 M) on self-assembly of silver carp myosin at 4 °C was investigated in terms of microstructure, conformation, intermolecular interactions, and particle size distribution. During setting at 4 °C, the self-assembly of myosin showed an obvious concentration dependence. At low concentrations (<0.3 M), myosin assembled into filaments mainly through rod-rod ionic linkages, and showed significantly (P < 0.05) higher turbidity and lower solubility than at ≥0.3 M. The addition of NaCl (0.3 − 0.6 M) led to the extension and dissolution of myosin by interfering with electrostatic interactions. The myosin assemblies gradually became smaller and more uniform. The solubility and Ca 2+ -ATPase activity reached a maximum at 0.6 M NaCl. When the concentrations increased to >1.0 M, myosin further assembled into filaments dominated by hydrophobic interactions. Both rod-rod and head-head interactions contributed to the myosin filaments at high concentrations (1.0 − 3.0 M). The solubility and uniformity of the myosin assemblies decreased as the NaCl concentration increased from 1.0 to 3.0 M.

The coupling effect of adipic acid and NaCl on electrochemical migration (ECM) of SAC305 solder alloy for printed circuit boards was studied using a self-designed high-throughput preparation and electrochemical test platform. The promotion effect of 1000 ppm NaCl on anodic dissolution and ion migration steps in the electrochemical migration substantially increased the dendrite formation probability ( P dendrite ) of SAC305 solder alloy. The low P dendrite in 1000 ppm adipic acid was attributed to the enhanced resistance to ion migration step by the formation of complex precipitates. Adding 1 ppm adipic acid into 1000 ppm NaCl could effectively decrease P dendrite due to the co-formation of hydroxide and complex precipitates, while increasing adipic acid concentration (from 10 ppm to 1000 ppm) instead raised P dendrite because hydroxide precipitates could transform into dendrite source at the cathode.

The aim of this study is to enhance the classification performance of the back-propagation-artificial neural network (BP-ANN) algorithm for NaCl, NaOH, β-phenylethylamine (PEA), and their mixture, as well as to avoid the defects of the artificial bee colony (ABC) algorithm such as prematurity and local optimization. In this paper, a method that combined an improved adaptive artificial bee colony (IAABC) algorithm and BP-ANN algorithm was proposed. This method improved the ABC algorithm by adding an adaptive local search factor and mutation factor; meanwhile, it can enhance the abilities of the global optimization and local search of the ABC algorithm and avoid prematurity. The extracted score vectors of the principal component of the ultraviolet (UV) spectrum were used as the input variable of the BP-ANN algorithm. The IAABC algorithm was used to optimize the weight and threshold of the BP-ANN algorithm, and the iterative algorithm was repeated until the output accuracy was reached. The output variable was the classification results of NaCl, NaOH, PEA, and the mixture. Meanwhile, the proposed IAABC-BP-ANN algorithm was compared with discriminant analysis (DA), sigmaid-support vector machine (SVM), radial basis function-SVM (RBF-SVM), BP-ANN, and ABC-BP-ANN. Then, the above algorithms were used to classify NaCl, NaOH, PEA, and the mixture, respectively. In the experiment, four indicators, accuracy, recall, precision, and F-score, were used as the evaluation criteria. In addition, the regression equation parameters of the mixture for the testing set were obtained by BP-ANN, ABC-BP-ANN, and IAABC-BP-ANN models. All of the results showed that IAABC-BP-ANN exhibits better performance than other algorithms. Therefore, IAABC-BP-ANN combined with UV spectroscopy is a potential identification tool for the detection of NaCl, NaOH, PEA, and the mixture.

The effect of an external DC electric field on the inhibition behavior of Zn-MOFs in 0.5 mol/L NaCl solution for copper was investigated via electrochemical measurements and various characterization techniques. Results indicated that the corrosion inhibition efficiency of the Zn-MOFs decreased under strong electric field intensities, which went from 94.2% to 61.7%. The corrosion inhibition efficiency of the materials decreased with increasing electric field duration when maintained at a certain electric field intensity. When the electric field duration time was 6 h, 12 h, 18 h and 24 h, the corresponding efficiency was 90.4%, 86.8%, 78.2% and 61.7% respectively. The effect of an electric field on the corrosion inhibition performance of the Zn-MOFs could essentially be attributed to changes in the structure of the material framework.

Intermediate temperature NaCl–AlCl3-based Al-ion batteries are considered as a promising stationary energy storage system due to their low cost, high safety, etc. However, such a cheap electrolyte has a critical feature, i.e., strong corrosion, which results in the short cycle life of the conventional Al-metal anode and also limits the development of the NaCl–AlCl3-based Al-ion batteries. A noncorrosive electrolyte may be a good choice for addressing the above challenge, while it is difficult to obtain the electrolyte that has advantages of both noncorrosion and low cost. Therefore, here, we report a Ga-metal anode in the affordable NaCl–AlCl3 electrolyte for constructing a long-life stationary Al-ion energy storage system. This featured liquid metal anode shows good alloying and dealloying processes between metallic Ga and Al, as well as renders superior stability of the interface between the electrolyte and the anode (e.g., smoothly running for over 580 h at 2 mA cm–2). No-corrosion and no-pulverization problems appear in this novel liquid/liquid interface. Those advantages demonstrate that the liquid Ga-metal anode has a great promise for the improvement of the NaCl–AlCl3-based Al-ion batteries for large-scale stationary energy storage applications.

Reducing salt intake without affecting the saltiness perception remains a great challenge for the food industry. Herein, the demulsification of water droplets and air bubbles was controlled to modulate the release of sodium from oleogel-stabilized water-in-oil emulsions (OGEs) stabilized by monoglyceride crystals. The effect of monoglycerides with carbon chain length (glycerol monolaurate-GML, glyceryl monostearate-GMS, and glycerol monopalmitate-GMP) and homogenization methods (hand-shaking or high-speed blender) on sodium release and saltiness was investigated by in vitro and in vivo oral processing tests. Milky-white stable emulsions were formed with both water droplets and air bubbles dispersing in the oil phase, regardless of the selected homogenization methods. Air bubbles were more unstable than water droplets during oral digestion. GML OGEs with more and larger air bubbles and the lowest hardness exhibited the highest sodium release rate and the strongest saltiness, independent of homogenization methods. The balance between air bubbles and water droplets in the GMS and GMP OGEs caused slower sodium release and lower saltiness. Overall, the presence of air bubbles in NaCl-loaded W/O oleogel-based emulsions was shown to have important implications for tailoring their sodium release and saltiness.

Melamine modified carbon dots (Me-CDs) was synthesized by hydrothermal method and used as effective corrosion inhibitor for Q235 carbon steel in 3.5 wt% sodium chloride (NaCl) solution. The microstructure and surface properties of Me-CDs were characterized using XRD, FTIR, XPS and TEM. The corrosion inhibition behavior and mechanism of Me-CDs for carbon steel were investigated using weight loss and electrochemical methods, in combination with some surface characterizations (including SEM, AFM and contact angle tester). Results showed that Me-CDs as mixed-type adsorbent inhibitor could effectively prevent carbon steel from corrosion, and the maximum corrosion inhibition efficiency can reach 92.36% at 200 mg/L. The absorption of Me-CDs conformed to Temkin adsorption model, involving both chemisorption and physisorption . Based on the results of characterization analysis, the chemisorption from multiple adsorption centers, physisorption by blocking and barrier effect, and the formation of hydrophobic film on the surface of carbon steel was proposed to clarify the corrosion inhibition mechanism of Me-CDs.
