Abundant sodium resources provide compelling competitive advantage for sodium-ion battery (SIBs) applications. Correspondingly, it is urgently required to develop high-performance and low-cost anode materials for SIBs. Here, we report a composite of antimony nanoparticles anchored on N/S co-doped 3D carbon for superior SIB anodes. During the synthesis, NaCl exerts a “pinning effect” to restrict the growth of antimony in the carbon matrix and results in nano-sized antimony particles. Given the enhanced-charge/ion-transfer kinetics ensured by nano-Sb and the structural advantages derived from the N/S co-doped 3D porous carbon, which not only remain robust upon cycling but also undergo graphitization by the ion shuttle effect to stimulate a stronger electrochemical response during the activation process, this composite maintains a 98.9% capacity ratio over 20,000 cycles at 10 A g -1 . Furthermore, molecular dynamics simulations reveal that the degree of graphitization has a linear relationship with the ionic radius.

The accumulation and uniformity of the distribution of the marinade throughout the meat over time is significantly influenced the quality of marinated meat. Based on the commonly used wet-immersion marinating method. Hyperspectral imaging (HSI) was used to quantitatively analyze the diffusion dynamics of NaCl in beef, which has advantages of rapid time dimension and continuous space dimension when acquiring optical signal of samples. Additionally, finite element analysis (FEA) was used to simulate the NaCl in beef diffusion within a three-dimensional geometric representation. The distribution status of NaCl in the marinated beef was not uniform, according to the visualization findings of NaCl content based on HSI. The FEA simulation findings demonstrated that muscle tissue had a substantially greater NaCl diffusion rate than other tissues. The variability in diffusion behavior of NaCl was the primary cause of its uneven distribution in beef. In addition, based on the spectral peak displacement mechanism with NaCl content as the disturbance factor, 9 sensitive characteristic variables were extracted by two-dimensional correlation spectral analysis (2D-COS). Then the optimal quantitative analysis model was established by the long short-term memory network (LSTM) using characteristic variables, and the R P 2 and RMSEP were 0.9018 and 0.5342, respectively. This study provides a new idea and method for exploring the diffusion behavior of marinade in meat. The results have practical significance for the quality evaluation and control of marinated meat products.

The effects of rosmarinic acid (RA) (12, 60 and 300 μM/g protein) on the textural properties and stability of oxidized myofibrillar protein (MP) emulsion gels were investigated. A low dose (12 µM/g) of RA significantly prevented the loss of thiol and ε-NH 2 groups and the unfolding of the oxidized MP. However, a high dose of RA (300 µM/g) covalently and non-covalently interacted with the MPs, which induced a significant loss of thiol and ε-NH 2 groups and aggregation of the MPs, causing decreased solubility, resulting in a poor three-dimensional emulsion gel network, and hence, higher cooking loss and lower gel strength. Moreover, the emulsifying properties of the MP emulsion gel were jeopardized by 300 µM/g RA. A high concentration of NaCl (0.6 M) enhanced the interaction between RA and MPs, increasing deterioration of the internal structure and leading to extremely unstable emulsifying properties of the MP emulsion gel.

Photocatalytic technology is currently the most promising technology for environmental pollution control. The preparation of photocatalysts with excellent properties is the core of the development of photocatalytic technology. TiO 2 can form a heterojunction with g-C 3 N 4 , which can effectively inhibit the recombination of photogenerated electron–hole pairs, improve the mobility of photogenerated carriers, and thus improve the photocatalytic performance. In this study, NaCl was used as a template, and the loose and porous g-C 3 N 4 /TiO 2 heterojunction composite photocatalysts were prepared by the template method. Compared to the pure g-C 3 N 4 prepared by the conventional thermal polycondensation method and TiO 2 , the g-C 3 N 4 /TiO 2 heterojunction composite photocatalysts prepared in this study exhibited a greatly increased specific surface area, an improved light absorption performance, a significantly suppressed recombination of photogenerated electrons and holes. Furthermore, the g-C 3 N 4 /TiO 2 heterojunction composite photocatalysts exhibited excellent photocatalytic performance.

First principle molecular dynamics (FPMD) simulations in combination with experimental measurements are applied to investigate the phase transition behavior of NaCl-MgCl 2 eutectic salt from 823 to 573 K. First, the essential phase transition indexes of thermal expansion coefficient, density, melting point, and enthalpy of fusion for NaCl-MgCl 2 eutectic obtained by simulations and experiments are in good agreement with each other. Second, the micro-structural characteristics during phase transition are depicted by the temperature dependences of angular distribution function, radial distribution function and coordination number. The structural evolution of NaCl-MgCl 2 eutectic is illustrated from the rearrangement of polyhedral M g C l n 2 - n clusters, and it is founded that high and low temperature are conducive to the formation of 4-fold and 6-fold coordinated structure, respectively. Third, the ionic self-diffusion coefficients for NaCl-MgCl 2 eutectic are predicted and concluded that Mg 2+ behaves like a complex than as a free ion resulting in less diffusivity. Therefore, the shear viscosities of molten NaCl-MgCl 2 as well as the corresponding pre-exponential factor and activation energy are evaluated considering the solvodynamic mean radius of all the diffusive particles. Ultimately, two figures of merit for molten NaCl-MgCl 2 are deduced to evaluate the heat-transfer and heat-loss performance by integrating multiple thermal properties including density, viscosity, specific heat capacity and thermal conductivity. Overall, these simulation results are in satisfactory agreement with available reference data, indicating that the FPMD simulations work extremely well in predicting the thermophysical and structural properties of NaCl-MgCl 2 , which also provide insights for the applications of binary chloride salts in thermal energy storage.

Salt accumulation often occurs in conventional processes for textile wastewater treatment, which affects the dye removal efficiency and water recovery rate. Nanofiltration is a feasible way to fractionate dye/NaCl mixtures. In this study, to enhance the dye/salt separation efficacy, two-dimensional (2D) WS2 nanosheets were incorporated and coordinately bonded to polyelectrolytes for fabricating layer-by-layer hybrid nanofiltration membranes. The incorporation of WS2 enhanced the hydrophilicity and surface negativity of the membrane. Further, the stacking of WS2 nanosheets and their frictionless surface promoted water transportation in polyelectrolyte multilayers. WS2-incorporated membrane (2 wt %) exhibited the highest pure water flux and achieved separation factors of 7238 and 9036 during filtration of Conge red/NaCl and reactive black 5/NaCl binary solutions, respectively. Moreover, the instability of the multilayered polyelectrolyte membrane in high ionic strength solutions was overcome by the incorporation of WS2, and the WS2-incorporated membrane showed better antifouling performance toward model organic foulants.

The use of salts as grinding media to assist the mechanosynthesis, and the following one-pot mechanochemical post-synthesis, of hierarchically porous MOFs was carried out efficiently by ball milling. NaCl or KCl were used as a solid solvent to initially pre-grind with 1,3,5-benzenetricarboxylic acid (H3BTC) and copper acetate monhydrate, respectively, for 1 minute, then both mixtures were combined together for a further 20 minutes of grinding, and the resultant mixture was finally washed with ethanol and water to obtain the hierarchically micro-, meso- and macroporous HKUST-1 with a high yield. Moreover, the post-synthesis of these as-obtained hierarchically porous HKUST-1 was easily performed via grinding triethylenediamine (TED) with the above unwashed crude-products for 20 minutes. By adjusting the amount of NaCl and TED added, we simply fabricated the pore- and function-adjustable hierarchically porous HKUST-1. Furthermore, these as-obtained HKUST-1 products showed high performance in the capture of volatile iodine.

In this paper, a coupled optimization method of optical and thermal performance was explored by us. The microscopic structure of NaCl-Al 2 O 3 based composite phase change material (CPCM) was established, the thermal properties were obtained by means of molecular dynamics (MD) simulations combined with experiments. The first principle calculations were also carried out to investigate the optical performance of the CPCM. The results indicated that the addition of nano Al 2 O 3 can effectively improve the thermal performance and thermal stability of CPCM, when the mass fraction of Al 2 O 3 nanoparticles in CPCM are 2.2 wt% and 7.2 wt%, the mass loss of CPCM samples were 0.14 % and 0.016 % after 100 times cycle, and the thermal conductivity and specific heat capacity can be increased by 15.45 % and 7.63 % at most. In addition, it was found that the optical performance of the CPCM can be also significantly improved. The microscopic coupled optimization mechanism was successfully revealed by the calculation of phonon density of state and band structures, which is desired to be a candidate approach to improve the photo-thermal conversion efficiency of the heat absorber contained in CSP (concentrating solar power) system.

In this work, a low-cost and easily purified small molecule dibenzimidazole compound (BBI) was synthesized by the condensation of o-phenylenediamine and malonic acid. BBI was a new corrosion inhibitor for magnesium alloys and its corrosion inhibition behavior on AZ91D magnesium alloy was studied by electrochemical measurements, surface analysis and theoretical calculations in 3.5 wt.% NaCl solution at 30 °C. The adsorption behavior and corrosion inhibition mechanism of BBI molecules were discussed. It was found that BBI exhibited excellent inhibition effect on the corrosion of magnesium alloy. When BBI concentration was 0.25 g/L, the optimal corrosion inhibition efficiency was 86.2%. The adsorption of BBI molecule obeyed Langmuir adsorption on the surface of magnesium alloy, and one side of BBI molecule was adsorbed on the surface of magnesium alloy in parallel through physical and chemical mixed adsorption.

Providing texture-modified food for dysphagia patients has been one of the most effective treatment methods. The current study aimed to evaluate a specially designed commercial pea protein isolate (PPIc) -based texture-modified food by ultrasonic treatment (US, 390 W; 20 min) at different NaCl concentrations by adjusting its texture and structure. The results showed that US can improve the texture properties of PPIc within a certain range of NaCl concentration (0.03–0.6 M). The prepared PPIc samples exhibited good mastication and swallowing characteristics with proper viscosity (33.31–704.2 mPa·s), softness (gel strength <30 g), wetness (good solubility and water holding capacity), etc. While with ultrasonic condition at the low NaCl concentration (0.1 M), the PPIc could achieve an overall superior textural attribute than those with other salt concentrations. Further research showed that US-NaCl combination could facilitate PPIc gel to maintain a more proper dysphagia texture, not only by reducing the number of pores and unfolding structures during processing, but also by enhancing the surface area of protein particles and cross-linking interaction of proteins through more exposure of sulfhydryl groups. It was also found that the β-turns of untreated-PPIc transformed to β-sheets at high salt concentration, whereas inverted transformation was observed at low NaCl concentration (0.03 M). We further unveiled US significantly enhanced the solubility, water holding capacity , and gelling ability of the PPIc. Overall, US-NaCl would be a promising method for the preparation of modified textural PPIc, which provides a new approach to formulate low-salt, high-nutrition, and customizable food for special populations such as the elderly and dysphagia.

Graphical Ramping rate matters in pyrolysis : Hybrid Co/N−C electrocatalysts were synthesized using NaCl as template via direct pyrolysis method. Ramping rates during pyrolysis was evidenced to affect the porosity and composition of the obtained electrocatalysts due to the different diffusion rates and decomposition reaction of precursors, which have significant influences on their catalytic activities toward oxygen reduction. Pyrolysis is a necessary procedure for synthesizing carbon-based nonprecious metal electrocatalysts via stimulating interaction and carbonization of precursors. In this work, ramping rates that correlated with thermal gradient has been investigated to reveal the configuration evolution of the precursors. Spectra characterizations demonstrated that ramping rates affected decomposition and aromatization of precursors. Increasing ramping rates improved the percentage of doped nitrogen and defects, promoting dispersion of Co atoms in the carbonaceous matrix and increasing density of active sties. In addition, the size variation of NaCl template under different ramping rates modifies the porous structure of Co/N−C electrocatalysts, greatly increasing the percentage of macropores and micropores at rapid ramping rates. As a result, electrocatalysts obtained at 5 °C min −1 exhibit comparable catalytic activity to that of Pt/C due to highly dispersed active sites and rational percentage of porosity, facilitating the sufficient reaction of oxygen along the catalysts. These results shed lights on regulating physical properties of carbonaceous electrocatalysts.

Phosphorus (P) starvation in rice facilitates the reutilization of root cell wall P by enhancing the pectin content. NaCl modulates pectin content, however, it is still unknown whether NaCl is also involved in the process of pectin regulated cell wall P remobilization in rice under P starved conditions. In this study, we found that 10 mmol/L NaCl increased the shoot and root biomasses under P deficiency to a remarkable extent, in company with the elevated shoot and root soluble P contents in rice. Further analysis indicated that exogenous NaCl enhanced the root cell wall P mobilization by increasing the pectin methylesterase activity and uronic acid content in pectin suggesting the involvement of NaCl in the process of cell wall P reutilization in P starved rice roots. Additionally, exogenous NaCl up-regulated the expression of P transporter OsPT6, which was induced by P deficiency, suggesting that NaCl also facilitated the P translocation prominently from root to shoot in P starved rice. Moreover, exogenous abscisic acid (ABA) can reverse the NaCl-mediated mitigation under P deficiency, indicating the involvement of ABA in the NaCl regulated root cell wall P reutilization. Taken together, our results demonstrated that NaCl can activate the reutilization of root cell wall P in P starved rice, which is dependent on the ABA accumulation pathway.
