Paper-based cultural relics possess great historical and cultural value but are vulnerable to irreversible degradation from high-energy ultraviolet (UV) light exposure and acidification, threatening their long-term preservation. Current paper protection predominantly relies on exogenous materials with single functions, which not only provide limited protective effects but also pose a risk of secondary damage. In this study, we developed a Dual-Functional paper by directly integrating a carbon quantum dot–magnesium hydroxide (CQDs@Mg(OH)2) nanocomposite into the papermaking process, thereby endowing the paper with intrinsic resistance to both acidification and UV-induced photodegradation, which reduces the reliance on subsequent protective treatments and fundamentally enhances the paper’s longevity. The results demonstrate that the functional paper integrated with CQDs@Mg(OH)2 nanocomposites shows good structural compatibility and strong resistance to degradation. Under the conditions of both UV exposure and dry-heat aging, the functional paper demonstrates excellent resistance to photooxidative and acid-induced degradation, indicating its strong potential for extending the longevity of paper-based materials. Additionally, the fluorescent properties of CQDs reveal promising potential as optical anticounterfeiting markers. This work opens an avenue for the design of long-lasting functional paper enabled by carbon-based materials, with promising applications in the preservation of paper-based cultural heritage.

Hardness is one of the basic parameters of water, and a high-level hardness of drinking water may be harmful to human health. Thus, it is very important to monitor drinking water hardness. In this work, a portable lateral flow distance-based paper sensor for the semi-quantitative detection of drinking water hardness is demonstrated. In the presence of Ca 2+ /Mg 2+ , the hydrogel can be formed via the chelation between sodium alginate and Ca 2+ /Mg 2+ , inducing a phase separation process. The viscosity change of the sodium alginate solution is directly related to the Ca 2+ /Mg 2+ concentration and can be determined by the water lateral flow distance on test strips. The sensor successfully realizes the quantification of Ca 2+ and Mg 2+ in the range of 0–10 mmol L -1 and 4–20 mmol L -1 , respectively. The recoveries are found varied from 95% to 108.9%. The water hardness is acceptable for drinking if the C r values lies in the range of 0.259 to 0.419, and it is high with the C r value above 0.595. Remarkably, the performance of the sensor is comparable with the commercial kit for real water samples, which avoids the subjective judgment. Overall, this method provides a portable approach for semi-quantitative detection of drinking water hardness with the merits of convenience and low cost, which shows great potential for the potential application.

Driven by the demand for lightweight materials, magnesium has gained significant interest due to its abundance and low density. This study systematically investigated the effects of mechanical ball milling time and sintering temperature on the microstructure and mechanical properties of a powder-metallurgy-processed Mg-Al-Ti alloy. The results established a correlation between ball milling and sintering processes, demonstrating that regulating precursor powder characteristics effectively enhances sintering diffusion efficiency. By precisely controlling sintering temperature and powder particle size characteristics, the alloy achieved high density, hardness, and strength at relatively low temperatures, demonstrating comprehensive performance. Optimal properties were obtained at 420 °C sintering conditions: relative density of 98%, hardness of 172 HV, compressive strength of 367 MPa, and nanoscale Young’s modulus reaching 45.15 GPa. Further analysis indicated that intermetallic compounds formed during sintering contributed significantly to the hardness enhancement, with the strengthening mechanism primarily attributed to the synergistic effects of precipitation and solid solution strengthening. The work provides a theoretical basis for further development of high-performance materials by subsequent processing.

Magnesium alloys, the advanced lightweight structural materials, have been successfully applied in the manufacturing field. Unfortunately, their poor corrosion resistance restrains the potential wide applications. In this work, anti-corrosion coatings were fabricated via the in-situ growth of the corrosion inhibitors intercalated magnesium-aluminum layered double hydroxide (Mg–Al LDH) on AZ31 magnesium alloy and then post-sealing it by a super-hydrophobic coating. SEM, XRD, EDS, FTIR, XPS and contact angle test were conducted to analyze physical/chemical features of these coatings. Potentiodynamic polarization curves and electrochemical impedance spectroscopy were recorded to assess the anti-corrosion performance of prepared coatings. Surprisingly, Mg–Al LDH with molybdate intercalation and lauric acid modification achieves the excellent corrosion inhibition performance (99.99%) due to the multicomponent synergistic effect such as the physical protection of Mg–Al LDH, the corrosion inhibition of molybdate and super-hydrophobic properties of lauric acid. This work presents a scientific perspective and novel design philosophy to fabricate the efficient anti-corrosion coating to protect magnesium alloys and then expand their potential applications in other field.

Inspirations from nature have led to extensive developments of biomimetic nonwetting surfaces and intelligent self-healing technologies toward corrosion protection of metals. Integration of both intriguing features contributes to achieving diversified protections. In this work, we engineered a novel anticorrosion system composed of a plasma electrolytic oxidation (PEO) film, a layered double hydroxide (LDH) film and a lubricant-infused slippery surface on Mg alloy . The PEO film grown in situ on Mg alloy could render a moderate corrosion barrier, and the sandwiched LDH film integrated ternary roles involving loading corrosion inhibitor, anchoring lubricant and sealing PEO defects. The outermost slippery surface exhibited durable repellence against water and also self-reparable capability to surface damage. The robust and self-reparable film barrier coupled with active corrosion inhibition endowed this system with superb anticorrosion performance. The dynamic self-healing processes associated with barrier regeneration and corrosion inhibition were substantiated at microscale using scanning Kelvin probe and scanning vibrating electrode technique, respectively. It is expected that this research would shed light on the design of multifunctional anticorrosion systems for Mg alloy.

Mg-Al layered double hydroxides (LDH) (F-MgAl-LDHs and O-MgAl-LDHs) and Mg-Al layered double oxides (LDO) (F-MgAl-LDO and O-MgAl-LDO) nanosheets were prepared using a modified co-precipitation and oven/freeze dry route for adsorption of uranium. The freeze dry could evidently promote the adsorption ability. It’s resulted from larger specific surface (F-MgAl-LDO > F-MgAl-LDHs > O-MgAl-LDO > O-MgAl-LDHs) and pore size, as well as sufficient expose of vacant sites in the inner struture of F-MgAl-LDHs and F-MgAl-LDO. The pH, shaking time, initial uranium concentation and temperature influenced the adsorption capacity of F-MgAl-LDHs, O-MgAl-LDHs, F-MgAl-LDO and O-MgAl-LDO, while ionic strength exerted slightly little influence. Na 2 CO 3 highlighted the best desorption effectivity, with desorption efficiency of 97.84% for F-MgAl-LDHs and 98.52% for F-MgAl-LDO, respectively. It is noteworthy that maximum adsorption capacity of F-MgAl-LDO reached 1099.93 mg/g, locating the top rank in the uranium-specific adsorbents. The adsorption conformed to the pseudo-second-order model, indicating chemical adsorption in nature. The thermodynamic was also investigated. The adsorption mechanism was determined that M-O and C-O bonds participated the complex process in the uranium adsorption. The study proposed the freeze dry as an efficient method to promote adsorbent performance.

Zn-Al-Mg coated steel (ZM-steel) has emerged as a preferred material in automotive and infrastructure applications, yet its long-term durability remains challenged by localized corrosion in chloride-rich environments. Herein, a sustainable and scalable corrosion protection strategy based on the in-situ formation of layered double hydroxide (LDH) films intercalated with benzothiazole (BTZ) was reported. By exploiting the controlled corrosion of ZM-steel surface in BTZ-containing NaCl solution, compact LDH architectures spontaneously formed, incorporating BTZ molecules within their interlayers. The resulting hybrid coating integrated the physical barrier effect of LDH with the release of BTZ anions, enabling interfacial passivation and sustained corrosion inhibition. Comparative electrochemical tests revealed that BTZ-containing NaCl solution yielded markedly enhanced corrosion-resistance as compared to NaCl solution or bare BTZ solution, with charge transfer resistance increasing from 9.44 × 10 2 to 9.13 × 10 4 Ω·cm 2 . Moreover, epoxy-overcoating effectively suppressed filiform corrosion (FFC) of ZM-steel substrate for over 35 days. Unlike conventional hydrothermal or carbonate-assisted routes for LDH fabrication, this precursor-free strategy proceeds under ambient conditions without additional reagents, underscoring its simplicity, efficiency, and scalability. These findings demonstrate that the moderate corrosion is beneficial to the formation of LDH on ZM-steel surface.

Sepiolite (SEP)-based solid amine is considered as a low-cost adsorbent for CO 2 capture. However, the inferior physical structure and constrained chemical properties impede its further development. Herein, by utilizing magnesium-containing waste liquid from acid-treatment sepiolite as a precursor, MgO nanostructures that act as pillars, permanently propping open the sepiolite layers and creating a Mg pillared sepiolite support (SEPMgO) with a high surface area (279 m 2 /g) and large pore volume (0.75 cm 3 /g), achieving the resource utilization of waste. Pentaethylenehexamine (PEHA) was impregnated onto SEPMgO to synthesize an adsorbent. The SEPMgO-PEHA 0.9 adsorbent achieved the optimal CO 2 adsorption capacity of 3.2 mmol/g at 60 °C. The adsorption capacity only decreased by 10 % after ten cycles. In-situ DRIFTS analysis reveals the capture process of SEPMgO-PEHA 0.9 follows zwitterion and base-catalyzed hydration mechanism, with the latter being significantly promoted by the alkaline environment provided by magnesium oxide. Life cycle assessment validated a low carbon footprint of 0.136 t of CO 2 emissions per tonne captured, marking a 25% reduction compared to SBA-15-based sorbents. The SEPMgO-PEHA 0.9 adsorbent is a promising candidate for the application of mineral materials in CO 2 capture and sustainable development.

Three phosphates Rb2Zn3(P2O7)2 and Cs2M3(P2O7)2 (M = Zn and Mg) were successfully synthesized by a high-temperature solution method. Their structures were determined by single-crystal X-ray diffraction, which shows that the three structures all display three-dimensional [M3P4O20]14− (M = Zn and Mg) frameworks composed of isolated P2O7 dimers and MO4 (M = Zn and Mg) tetrahedra with Rb+/Cs+ cations located in the space of the frameworks to balance charges. But owing to the cationic size effect, they are not iso-structural. Rb2Zn3(P2O7)2 crystallizes in the non-centrosymmetric P21 space group, whereas Cs2M3(P2O7)2 (M = Zn and Mg) crystallize in the centrosymmetric P21/c space group. And Rb2Zn3(P2O7)2 exhibits a second harmonic generation (SHG) response as large as that of KH2PO4 (KDP). Combining electronic structure and SHG density calculations, we studied the effects of ZnO4 tetrahedra on the SHG response of Rb2Zn3(P2O7)2. Furthermore, a structural comparison is also carried out in Rb2Zn3(P2O7)2 and Cs2M3(P2O7)2 (M = Zn and Mg).

In order to refine the microstructure and improve the performance of direct energy deposited (DED) additively manufactured Al–Mg–Sc–Zr alloy, TiC-modified Al–Mg–Sc–Zr composites were prepared by DED and the effect of TiC content on the microstructure and performance was studied. In the absence of TiC particle, the microstructure of Al–Mg–Sc–Zr alloy prepared by DED consisted of fine grains with average size of 8.36 μm, and well-dispersed nano-Al 3 (Sc,Zr) particles inside the grains and Mg 2 Si phase along the grain boundaries. With the addition of 1 wt% TiC, the microstructure of TiC/Al–Mg–Sc–Zr prepared by DED became finer apparently compared with that without TiC; while the further increase of TiC content to 3 wt%, the microstructure of TiC/Al–Mg–Sc–Zr prepared by DED became coarser with appearance of a new kind of needle-like (Ti,Zr) 5 Si 3 phase. Also, the addition of TiC decreased the porosity of Al–Mg–Sc–Zr prepared by DED. Simultaneously, after the addition of TiC, the tensile strength increased from 283.25 MPa to 344.98–361.51 MPa, and the elongation increased from 3.61% to 9.58–14.10%. The potential mechanism of the microstructure evolution and strength improvement was discussed. This research will provide new insights into the available metal matrix composites by laser additive manufacturing (LAM).

In this paper, we report on the fabrication of MXenes sandwiched by carbon nanospheres (MXenes@C) and their application as an electrode for magnesium-ion storage. The heterostructure synthesis is realized via electrostatic interactions between negatively charged 2D MXene nanosheets and positively charged 3D carbon nanospheres. This approach effectively opens up the interlayer and prevents the restacking of MXene nanosheets, thus promoting the electrolyte transport and shortening the ion diffusion path. Through ex situ X-ray diffraction characterization and density functional theory computations, the magnesiation/demagnesiation mechanism and Mg-migration kinetics of the tailored Ti3C2Tx@C nanospheres are elucidated. Using Ti3C2Tx@C as a cathode for magnesium-ion batteries, a remarkable reversible specific capacity (198.7 mA h g−1 at 10 mA g−1), outstanding rate capability (123.3 mA h g−1 at 200 mA g−1), and impressive cycling stability (∼85% capacity retention after 400 cycles) are achieved. This method can also be applied to other MXenes, such as V2CTx, to prepare a sandwich-structure with nice rate performance and cycle life. The synthesis of MXene@C nanospheres using a simple self-assembly method offers new and feasible avenues to develop promising Mg-storage materials with excellent capacity and long cycle life.

High-entropy oxides (HEOs) with numerous functional features such as high structure stability and superionic conductivity are considered as promising candidates of electrode materials for lithium-ion batteries (LIBs). In this study, a series of single-phase spinel-structured high-entropy oxides (FeCoNiCrMnXLi) 3 O 4 (X = Cu, Mg, Zn) consisted of seven metal elements at equal molar ratio were synthesized by solid phase method. In-situ high-temperature XRD technique was used to investigate the structure evolution of (FeCoNiCrMnZnLi) 3 O 4 and a single-phase HEO was acquired at 900 °C. As the anode of LIBs, all the HEOs (FeCoNiCrMnXLi) 3 O 4 display excellent cyclic stability and rate capability owe to the expedite three-dimensional Li + transport pathways of spinel structure, the entropy-dominated phase stabilization effect together with the abundant oxygen vacancies introduced by the incorporation of Li + . In comparison, the (FeCoNiCrMnZnLi) 3 O 4 anode containing electrochemical active Zn with tetrahedral coordination structure shows better electrochemical lithium storage performances among the three samples. The ex-situ XRD of (FeCoNiCrMnZnLi) 3 O 4 during the discharge/charge procedure shows an amorphous state structure after the first lithiation process and it retained for the de-lithiation process. This work provides a new strategy to design high-entropy energy-storage material and pave the way for understanding the storage mechanism of HEOs.
