With the escalating environmental impact of petroleum-based plastics, natural polysaccharide-protein composite films have demonstrated significant potential as eco-friendly materials for food packaging. However, research on integrating bioactive metal-organic frameworks (MOFs) with Zein-based matrices to develop multifunctional active packaging remains underexplored. This study developed a novel composite film by encapsulating cinnamaldehyde (CA) within a magnesium-gallic acid-MOF (Mg-GA-MOF) and incorporating it into an ethyl cellulose (EC)/Zein matrix for pork preservation. The optimized CA@Mg-GA-MOF/EC/Zein-4% film with a thickness of 0.14 mm demonstrated remarkable mechanical properties, including a tensile strength of 55.75 MPa and an elongation at break of 5.46%. It exhibited low water vapor permeability at 5.87 × 10 −7 g·m −1 ·s −1 ·Pa −1 . The film also showed strong antibacterial activity, inhibiting growth by up to 99.73% against Escherichia coli and 89.26% against Staphylococcus aureus , as well as notable antioxidant properties with DPPH and ABTS scavenging rates of 59.70% and 49.71%, respectively. Furthermore, the composite film demonstrated sustained release characteristics for CA and GA and excellent biocompatibility. Non-covalent interactions between the components contributed to the improvement of functional properties of the film. In pork preservation trials, the composite film effectively delayed microbial growth, protein degradation, and lipid oxidation. Based on the total viable count safety limit (6 log CFU/g, GB 4789.2–2016), the film extended the shelf life of pork by 7 days compared to the control group. This study presents the first use of Mg-GA-MOF for the co-delivery of CA and GA within the EC/Zein film, offering a novel strategy for high-performance active food packaging.

Magnesium-lithium (Mg-Li) alloys are promising lightweight materials for engineering applications, but their use is limited by poor wear and corrosion resistance. To address those challenges, micro-arc oxidation (MAO) coatings were fabricated on Mg-Li alloy LA81 using electrolytes containing conductive ceramic nanoparticles (TiBCN). Results suggest that TiBCN enhances electrolyte conductivity and altering the arc discharge behavior, thereby reducing overall porosity of the resultant MAO coatings. Comprehensive characterization including measurements of coating thickness, microstructure, triboelectrochemical and corrosion resistance identify 2.5 g/L TiBCN as the optimal concentration. This formulation exhibits enhanced corrosion resistance, wear resistance and a notably low pore density. Three-dimensional evolution of corrosion in the optimized MAO coating was examined using synchrotron X-ray computed tomography. In corrosive environments, the combined effects of corrosion and expansion of corrosion products alter size, shape, and number of microdefects in MAO coatings over time. These changes were driven by the interactions between localized corrosion propagation and the accumulation and expansion of corrosion products. Ultimately, neighboring micro-defects merged, forming interconnected through-pores and accelerating MAO coating degradation.

Addressing the inhibitory influence of the oxide layer on the ignition and combustion of aluminium particles stands as one of the pivotal factors in facilitating its utilisation as an amphibious fuel. In this investigation, leveraging the distinctive properties of oxalic acid (OA), which is prone to decomposition and gas generation and holds substantial optimisation potential, surface modification of aluminium particles was conducted in conjunction with boron and magnesium particles. Al-based amphibious energetic composites (AEC) were thereby synthesised. Subsequently, their thermal behaviour, ignition and combustion characteristics, and action mechanism were investigated. The results indicate that the thermal behaviour of AEC samples encompasses dehydration, decomposition, and oxidation stages under amphibious atmospheres (namely, air, water vapour, and their mixtures). The atmosphere exerts a minimal influence on the thermal behaviour. Additives can remarkably enhance the ignition and combustion performance of aluminium particles. Owing to the readily decomposable OA and magnesium oxalate (OM) adsorbed on its surface and the highly reactive Mg particles, the ignition delay time of AEC in amphibious atmospheres is shortened by approximately 45–67 ms. Nevertheless, OA and OM merely function in particle dispersion. Consequently, the oxidising atmosphere in the environment has a substantial impact on the combustion performance of AEC samples. When O₂ is preponderant, the surface reactions of B and Mg clusters on the surface of aluminium particles release heat, thereby facilitating the combustion (the maximum combustion temperature is increased by approximately 600 K). When H₂O is dominant, this combustion-promoting effect diminishes. During combustion, the formation of metal oxides with high melting and boiling points, such as MgO, impedes the contact between the core active metals and oxidising gases, thereby reducing the self-sustained combustion performance of AEC samples. This research will offer crucial insights for the development and application of amphibious metal fuels.

N-type Mg 3 Sb 2 thermoelectric material has a complex crystal structure and electronic structure, which is a new thermoelectric material with excellent application prospects. The state density and band structure of Mg 24 Sb 16 and Bi/Se/Pr–Se/Nd–Se doped Mg 24 Sb 16 are first-principles calculated. Se/Pr–Se/Nd–Se doped increases the density of states around the Fermi level. Bi-doped does not impact the band structure because the electronic structure between Sb and Bi are similar. The band gap of Pr–Se/Nd–Se doped becomes narrower, which is more conducive to carrier transport and increases carrier concentration than that of single-doped Se. The experimental results show that Pr and Nd replace Mg to provide more electrons for the system. The carrier concentration of the co-doped sample increases significantly, thus improving the power factor and optimizing the samples' electrical properties. The highest ZT value of the Mg 3.2 Sb 1.5 Bi 0.49 Se 0.01 sample is 1.21. Pr–Se/Nd–Se co-doped ZT values are 1.67 and 1.74, respectively, 38% and 43% higher than the Mg 3.2 Sb 1.5 Bi 0.49 Se 0.01 sample. Multi-element doped is an effective strategy to improve the thermoelectric properties of materials .

Interfacial engineering is a decisive factor in stabilizing layered oxide cathodes for sodium-ion batteries (SIBs). Here, a synergistic Li/Mg/Si tri-doping strategy is introduced to simultaneously modulate the bulk lattice and interfacial chemistry of a P2-type Na 0.7 Li 0.03 Mg 0.05 Ni 0.25 Mn 0. 6 Si 0.07 O 2 (LMNMS) cathode. The dopants expand the c-axis lattice (11.195 Å) and strengthen surface transition metal (TM)-O covalency, yielding improved Na + diffusion kinetics and interfacial stability. X-ray photoelectron spectroscopy (XPS) and in situ Raman analyses reveal reduced surface oxygen vacancies (15% vs. 22% in the undoped sample) and suppressed electrolyte-induced oxygen redox, effectively mitigating the P2 → O2 phase transition. Electrochemical impedance spectroscopy confirms a 45% decrease in charge-transfer resistance, indicating enhanced interfacial charge transport. Benefiting from this coupled bulk-surface optimization, LMNMS delivers a high reversible capacity of 165 ± 3.2 mAh g −1 at 0.1C, an excellent rate performance (92 ± 2.5 mAh g −1 at 5C), and 90.5 ± 1.8% capacity retention after 200 cycles. This work highlights how multi-site doping tailors both the electronic and chemical nature of electrode interfaces, offering a design paradigm for high-performance and interface-stable sodium-ion batteries.

Phosphate ore reserves are insufficient for sustained human use, and the resource recovery of condensed phosphates in water bodies remains challenging. Herein, nanomagnesia (AA-MgO) with coexisting magnesium and oxygen vacancies was synthesized via the sacrificial template method using metal–organic frameworks. AA-MgO achieved efficient condensed-phosphate catalysis and simultaneous orthophosphate recovery in an electrocatalytic coupling adsorption system. Its unique dual-vacancy structure considerably enhanced its electrocatalytic performance. Under optimal conditions, AA-MgO showed adenosine triphosphate (ATP) and pyrophosphate (P ∼ P) removal rates of 98.75% and 98.20%, respectively, exhibiting 2.06–13.23 times better pseudo-first-order kinetics than commercially available MgO. After being regenerated thrice, AA-MgO maintained a > 70% removal rate, demonstrating excellent structural stability. Quenching and radical-trapping experiments confirmed that the catalytic process involved radical and nonradical pathways, with ·OH playing a dominant role in catalyzing ATP, while the nonradical pathway involving 1 O₂ contributed more significantly to P ∼ P degradation. Density functional theory calculations showed that the ATP adsorption energy was higher on the V Mg + V o surface than on the V o surface. Moreover, the energy barrier of the rate-determining step in P ∼ P degradation was lower on the former, indicating that this surface favored condensed-phosphate degradation. Finally, differential charge and electrochemical characterization revealed that AA-MgO exhibited superior electron transfer rates than MgO.

Rechargeable magnesium
batteries are promising next-generation
energy storage systems owing to the low cost and high natural abundance
of magnesium. However, their practical application is critically impeded
by the parasitic decomposition of conventional electrolytes at the
Mg anode, leading to the formation of a passivation layer, high desolvation
barriers, and poor cycling stability. Herein, triethyl phosphate (TEP)
is introduced as a cosolvent into the Mg(OTf) 2 + MgCl 2 -DME electrolyte to regulate solvation structures and interfacial
chemistry. Comprehensive spectroscopic and electrochemical analyses
reveal that TEP facilitates salt dissociation and reconstructs the
Mg 2+ solvation structure, thereby reducing the desolvation
barrier and promoting ion transport. Meanwhile, TEP contributes to
the formation of a stable and robust solid electrolyte interphase
on the Mg anode, effectively suppressing side reactions and enabling
uniform Mg deposition. The Mg||Mg symmetric cell exhibits stable cycling
for over 3500 h with an overpotential below 0.2 V at 0.1 mA cm –2 and 0.05 mAh cm –2 . The Mg||Mo asymmetric cell delivers a Coulombic efficiency of 99.4%
after 3000 h at 0.5 mA cm –2 and 0.25 mAh cm –2 . Furthermore, the Mg||α-MnO 2 full
cell maintains a discharge capacity of 176.9 mAh g –1 after 350 cycles at 0.1 C. This work provides a solvation-regulation
strategy for designing high-performance Mg electrolytes.

The production of high value-added liquid products by catalytic pyrolysis of cellulose has become an effective way to realize the efficient utilization of biomass. This work synthesized a series of Co-Ce, Co-Fe and Co-Mg composite metal catalysts and used them to obtain furans and ketones production. In addition, the CO 2 was used as a pyrolysis atmosphere to investigate the synergistic effect between CO 2 and the prepared catalyst. The results showed that the catalyst effectively promoted the depolymerization of cellulose and improved the oxygen transfer behavior between volatile matters during cellulose pyrolysis. As a reaction medium, CO 2 influenced the carbon distribution of products, thereby increasing syngas yield, and the CO 2 atmosphere promoted the formation of furans and ketones. Compared with those obtained by the non-catalytic pyrolysis in N 2 atmosphere, the relative contents of furans and ketones in the liquid products produced by the catalytic pyrolysis of cellulose in CO 2 atmosphere increased by about 13.38% and 9.8%. In the CO 2 environment, the generation ability for furans was Co-Mg catalyst > Co-Ce catalyst > Co-Fe catalyst, and the generation ability for ketones was Co-Ce catalyst > Co-Mg catalyst > Co-Fe catalyst. These works provide an important way for the efficient preparation of furans and ketones from biomass pyrolysis.

Background Toxic metals such as Pb(II) and Cd(II) have thrown great threat to human health. Adsorption has been drawn more attention due to its low-cost, easy process and extensive raw materials. However, high efficient and environmental-friendly adsorbents are still in great need. Furthermore, the quantitatively adsorption mechanisms of Pb(II) and Cd(II) remain unclear. MgO-loaded lotus stem biochar was proposed as a highly efficient adsorbent to removal aqueous Pb(II) and Cd(II). Methods MgO-loaded biochar was prepared by using lotus stalk as a precursor to be pyrolyzed with MgCl 2 impregnation. Adsorption isotherms , kinetics, thermodynamics experiments were carried out. SEM, XRD, FTIR, XPS, etc. were employed to characterize the adsorbent before and after adsorption. Significant findings The adsorption capacities of MgO-loaded biochar for Pb(II) and Cd(II) reached 1379.54 mg/g and 404.04 mg/g, respectively, which were 5 and 20 times higher than that of the original biochar. The adsorption kinetics and thermodynamics indicated that the adsorption process was a chemisorption-based heat absorption reaction, and the characterization results showed the main adsorption mechanisms were ascribed to ion-exchange, precipitation, surface complexation between biochar and Pb(II)/Cd(II) ions, in which the ion exchange mechanism was quantitatively confirmed. Finally, MgO-loaded biochar has been proved to be an efficient adsorbent.

A ZnSO4 electrolyte solution with impurity salts such as MnSO4 and MgSO4 is often used in zinc hydrometallurgical processes over a wide temperature range. CaSO4·2H2O(s) scaling and fluorine corrosion are two encountered problems in the process. Understanding the CaF2(s) solubility behavior in MSO4 (M = Zn, Mn, Mg) aqueous solutions at various temperatures helps remove Ca2+ and F– ions from the solution. However, CaF2(s) solubility data, especially at temperatures >298 K, have not been published yet. In this work, CaF2(s) solubilities in the CaF2–CaSO4–MSO4–H2O (M = Zn, Mn, Mg) quaternary systems and its subsystems of the CaF2–MSO4–H2O (M = Zn, Mn, Mg) at 348.15 K and the CaF2–CaSO4–MSO4–H2O (M = Zn, Mg) quaternary systems and the CaF2–MgSO4–H2O ternary system at 298.15 K are systematically measured. The results show that the CaF2(s) solubility in the MSO4 (M = Zn, Mn, Mg) aqueous solution of a certain concentration at 348.15 K is considerably higher than that at 298.15 K. At 298.15 and 348.15 K, the salting-in effect of MSO4 (M = Zn, Mn, Mg) on CaF2(s) solubility is enhanced with the order ZnSO4 < MnSO4 < MgSO4. At both temperatures, CaF2(s) solubilities in CaSO4·2H2O(s)- or CaSO4(s)-saturated MSO4 (M = Zn, Mn, Mg) aqueous solutions are generally lower than those in pure MSO4 (M = Zn, Mn, Mg) aqueous solutions. Particularly, the salting-in effect of MgSO4 on CaF2 is so strong that CaF2(s) dissolves completely and is converted to CaSO4·2H2O(s) and MgF2(s) in a concentrated MgSO4 aqueous solution. Hence, this study indicates that high temperatures and high salt concentrations increase the CaF2(s) solubility, making the removal of Ca2+ and F– ions from the system challenging. Further, the existence of impurity salts MnSO4 and MgSO4 makes it more difficult.

Filiform corrosion (FFC) challenges the application of Zn-Mg-Al coated steel (ZMA-steel). Herein, a self-healing coating loaded with functionalized mesoporous CeO 2 (mCeO 2 ) was developed to suppress FFC for ZMA-steel in saline media. mCeO 2 of large specific area readily accommodated benzotriazole and immobilized on g-C 3 N 4 generating a nanofiller (BTA@mCeO 2 /g-C 3 N 4 ) for epoxy matrix (EP). Strong barrier of lamellar g-C 3 N 4 , releasing BTA from nanofiller and generating Ce cations accounted for the long-term corrosion-resistance and self-healing effect of BTA@mCeO 2 /g-C 3 N 4 /EP system for ZMA-steel. Through taking full advantages of CeO 2 -based nanofiller, this work may provide an intelligent coating to solve FFC of ZMA-steel.

Eu 2+ -doped CaAlSiN 3 ‐type structure nitrides have been extensively studied as a red-emitting phosphors in white light emitting diodes (w-LEDs), but there are few reports of systematic research on the effect of solid solution substitution on their long persistent luminescent properties. In this work, a series of (M,Ca)AlSiN 3 :Eu 2+ (M = Sr, Mg) phosphors have been successfully synthesized by efficient combustion synthesis . We investigated the effect of Sr and Mg solid solution on long persistent luminescent properties. Thermoluminescence (TL) measurements were performed in those persistent phosphors to obtain direct experimental results on the trap depth. The results show that the SrAlSiN 3 :0.2 at% Eu 2+ phosphor exhibits the most intense red persistent luminescence with the persistent time of as long as 200 min at the threshold value of 0.32 mcd/m 2 due to the presence of more trap levels with suitable depths of 0.71 eV. Compared with the solid solution of Sr, the solid solution of Mg ions can increase the depth of trap levels in CaAlSiN 3 . Among them, Mg 0.2 Ca 0.8 AlSiN 3 :0.2 at% Eu 2+ phosphor achieved a maximum trap depth of 0.98 eV, making it a promising candidate for optical information storage applications.
