The limited durability and difficulty in repairing damaged lubrication layers are significant challenges hindering the practical applications of slippery liquid-infused porous surfaces (SLIPS) in fields such as marine antifouling. Here, we present an antifouling SLIPS coating with lubricant self-replenishing properties by grafting silica aerogel onto the layered double hydroxide (LDH) structure. The LDH structure is synthesized on the surface of Mg alloy via a hydrothermal reaction. Following the curing of polymethylsiloxane, silica aerogel is grafted onto the surface, and lubricating oil is infused to obtain the SLIPS coating. The LDH structure provides interconnected microcavities for lubricating oil storage, enabling self-replenishing properties when the lubricating layer is damaged, thereby enhancing the coating's durability. The SLIPS coating exhibits high performance in resisting adhesion of Chlorella vulgaris, Phaeodactylum tricornutum , and Pseudoaltteromonas nigrifaciens , achieving an over 80 % reduction in fouling organism coverage compared to bare Mg. This study presents a promising approach for the application of SLIPS in antifouling.

Rechargeable magnesium batteries (RMBs) are regarded as one of the promising candidates of next generation of battery technologies, but seriously hampered by the sluggish kinetics of Mg 2+ -related cathode reactions. A pertinent solution is adding Li salt into the electrolyte to build a hybrid Mg/Li battery (MLB), which combines the high safety of Mg anode and the fast reaction kinetics of Li + with the cathode material . Herein, we propose a novel, simple, and cheap dual-salt electrolyte for MLBs, namely MgCl 2 –LiCl/THF, based on the exceptional synergetic effect between MgCl 2 and LiCl in THF . The 1.0 M electrolyte demonstrated desired ionic conductivity (1.3 mS cm –1 ), good compatibility with Mg anode, and adequate oxidation potential (2.2 V vs. Mg) for typical organic cathode materials including poly(anthraquinonyl sulfide) (PAQS), poly(1,4-anthraquinone) (P14AQ), and dilithium salt of poly(2,5-dihydroxy-p-benzoquinonyl sulfide) (Li 2 PDHBQS). Unlike PAQS and P14AQ adopting MgCl + as inserted cation, Li 2 PDHBQS selected Li + to participate in the reaction. Therefore it demonstrated superior electrochemical performance to most of previously reported inorganic and organic cathode materials for MLBs, including a high reversible capacity (282 mAh g −1 ), a high rate capability (72% @ 2000 mA g −1 ), and a high cycling stability (70% @ 500th cycle). The combination of MgCl 2 –LiCl/THF electrolyte and Li 2 PDHBQS cathode provides not only a successful example of high-performing and affordable MLBs, but also insights of ionic species in the electrolytes and their interactions with organic cathode materials, which are very significant for the further development of RMBs.

Aqueous Mg-air batteries (MABs) are promising for the high-energy-density storage but suffer from severe self-corrosion of the Mg anodes and the discharge suppression due to the formation of oxide products. Tailoring electrolyte additives is deemed as a critical means to address these limitations. Herein, salicylate derivatives with different functional groups (hydroxyl, thiol, sulfonic, methyl) were systematically investigated through half-cell discharge characterizations combined with density functional theory (DFT)/molecular dynamics (MD) simulations. The results show that the discharge performance of Mg-air is promoted by the addition of 0.1 M SA, 5-SSA, TA and 2,6-DHB, but significantly reduced impeded by 3-MSA. Both experimental and DFT/MD results indicate that the presence of hydroxyl/thiol/sulfonic groups within SA molecule provides additional sites for its complexation with Mg ions suppressing the precipitation of hydroxides on the Mg anode surface, whereas the methyl group helps the adsorption of 3-MSA on the corroding Mg surface. This work suggests that the category and position of the functional group play critical roles in determining the effect of the electrolyte additive for Mg-air battery.

The process for preparing high-purity anhydrous yttrium chloride was investigated using a complex salt containing an excess of yttrium oxychloride. By studying the conversion of yttrium oxychloride, it was determined that the key to preparing high-purity anhydrous yttrium chloride lay in the synergistic actions of gas-solid and solid-solid reactions. On this basis, a purity control strategy involving the adjustment of the height-diameter ratio of the sample was proposed to inhibit hydrolysis and enhance the conversion rate. By adopting the purity control strategy, high-purity anhydrous yttrium chloride with a yttrium oxychloride content below 0.1 wt.% was obtained at 600°C when the height-diameter ratio of the samples exceeded 1.42. Finally, the experiments on preparing Mg-Y alloys through molten salt electrolysis validated the impact of the YCl3 purity on the electrolysis process. When the high-purity anhydrous yttrium chloride obtained by this strategy was utilized, the current efficiency could reach 83.7%.

A novel nonenzymatic electrochemical sensor with high sensitivity for detecting organic phosphate (OPS) in medicinal herbs was fabricated based on a Mg-Al layered double hydroxide (Mg-Al LDH) nanocomposite glassy carbon electrode (GCE) modified with a poly-m-amino-benzenesulfonic acid (p-m-ABSA) film. Depositing Mg-Al LDH nanocomposites onto the surface of the p-m-ABSA composite resulted in an effective electrical response by increasing the electrode surface area and enhancing the electron transfer process, so the electrocatalytic activity was significantly enhanced. The research illustrated that the fabricated sensor (Mg-Al LDH/p-m-ABSA/GCE) exhibited strong affinity, high sensitivity, and selectivity towards methyl parathion (MP) and fenitrothion (FNT). Scanning electron microscopy (SEM) was used to characterize the surface morphology of the modified electrode and showed that the p-m-ABSA film and a few p-m-ABSA nanoparticles were coated on the surface. The surface area of the electrode was further enlarged by Mg-Al LDH owing to their layered nanostructure. Under optimal conditions, the anodic current had a linear relation equal to 0.1∼20.0 µM MP and 0.01∼50.0 µM FNT, with detection limits (S/ N = 3) of 33.0 nM MP and 3.5 nM FNT, respectively. Furthermore, Mg-Al LDH/p-m-ABSA/GCE was successfully used for the detection of MP and FNT in Astragalus and Magnolia medicinal herb samples.

In this work, two novel fluorescent nanoprobes for detecting the anthrax biomarker 2,6-dipicolinic acid (DPA) have been developed based on a well-designed anionic sulphonated naphthalene derivative (L) by intercalating and coordinating Mg-Al-Ln-LDHs (Ln = Tb, Eu). The nanosensors exhibited good photostability and high reference fluorescence intensity due to a strong coordination interaction between the L and Al3+ ions of Mg-Al-Ln-LDH layers. Meanwhile, attributed to the antenna action of DPA in triggering the characteristic fluorescence emissions of Tb3+ and Eu3+ through energy transfer, the L-anchored Mg-Al-Ln-LDH nanoparticles exhibited high sensitivity and selectivity and remarkably stable ratiometric fluorescent detection of anthrax spore biomarkers in aqueous solutions, serum and actual spores. Benefiting from the intercalation and coordination of L into Mg-Al-Ln-LDHs, the obtained L@Mg-Al-Ln-LDHs can provide a reliable and stable reference signal for the fluorescence ratiometric detection of DPA with a limit of detection (LOD) of 11.6 nM and 3.56 × 103 spores per mL. More prominently, combining L@Mg-Al-Ln-LDH-based detection test strips with a smartphone demonstrates a reliable, rapid and simple method for real-time monitoring of anthrax biomarkers.

Mg 2+ /F − co-doped LiNi 0.5 Mn 1.5 O 4 cathode material was synthesized by a facile one-step solid-state process. The effect of Mg 2+ /F − co-doping on grain morphology, phase structure, and electrochemical properties was studied by a series of characterizations. Scanning-electron-microscopy images show that Mg 2+ /F − co-doped LiNi 0.5 Mn 1.5 O 4 (denoted LNMO-MF) particles grow larger than pure LiNi 0.5 Mn 1.5 O 4 particles. X-ray diffraction, Raman spectra , Fourier transformation infrared spectroscopy , X-ray photoelectron spectroscopy, and cyclic-voltammetry tests indicate that all samples mainly display a Fd -3m space group and more Mn 3+ ions in the LNMO-MF sample after Mg 2+ /F − co-doping, which is conducive to increasing the cationic disorder degree and enhancing the electronic conductivity of electrode material. Results show that the LNMO-MF cathode material delivers an excellent rate performance with discharge capacities of 142, 144, 140 136, 132, 124, 115, and 100 mAh g −1 at 0.2, 0.5, 1, 2, 3, 5, 7, and 10C (1C = 140 mAh g −1 ), respectively. Remarkably, LNMO-MF also shows cycling stability with a capacity retention of 86.2% at 5C after 400 cycles, which is much higher than that of pure LiNi 0.5 Mn 1.5 O 4 (67.7%). The improvement of LNMO-MF's electrochemical properties could be ascribed to the Mg 2+ /F − co-doping, delivering a more stable structure, better crystallinity , the highest Li + diffusion coefficient , and the lowest charge-transfer resistance.

Alkaline-earth metal-based MOF has many merits such as light weight, environmental friendliness and low cost, but it has rarely been used in energy storage and capacitive deionization (CDI). This paper presents a facile method for the fast synthesis of small-size magnesium formate MOF (Mg-MOF) under mild conditions by linker-free incubation in the presence of Mg(CH 3 COO) 2 ⋅ 4H 2 O and dimethylformamide. The formic acid was in situ formed as ligand to facilitate the formation of Mg-MOF. The effect of incubation time on the morphology of MOF crystals was investigated. The small and well-defined Mg-MOF particles with the size of ~ 18 nm were formed in 1 h incubation, characterized by scanning electron microscopy and X-ray diffraction. Following carbonization, the Mg-MOF-derived mesoporous carbon was obtained. N 2 -sorption isotherm confirmed the mesoporous structure. Cyclic voltammetry test indicated the good electric double-layer feature of the Mg-MOF-derived carbon electrode, and the impedance results showed the excellent conductivity. As a capacitor electrode material, it delivered the specific capacitances of 102 F/g by GCD (0.2 A/g). The Mg-MOF-derived carbon electrode was applied successfully for capacitive deionization (CDI) with a desalination capacity of 8.0 mg/g in a CDI device. A supper fast desalination rate of 1.1 mg/g/min was achieved due to the abundant mesoporous structure. The work provides a cost effective and environmentally friendly way for the synthesis of MOF-based carbon materials free of transition metal, and the prospects for CDI application have been demonstrated.

The symmetry-breaking structure can induce lattice distortion, modulate electron distribution, suppress carrier recombination, and optimizing catalytic activation via asymmetric atom interactions, which is of vital importance for improving the photocatalytic H 2 O 2 production activity. In this paper, the symmetry-breaking structures of Mg-modified ZnIn 2 S 4 microspheres are synthesized through a convenient single-step hydrothermal method using the gradient introduction amounts of Mg. X-ray absorption spectrum, X-ray photoelectron spectroscopy, and transmission electron microscopy indicate that the introduction of Mg can modify the bond lengths and crystal plane angles of the substrate material to construct a symmetry-breaking structure. The photocatalytic H 2 O 2 production performance of MZIS-15 is approximately 3.3-fold than ZnIn 2 S 4 up to 2797.0 μmol h⁻ 1 g⁻ 1 . Furthermore, femtosecond transient absorption spectra, photoelectrochemical measurements, and density functional theory (DFT) calculations reveal that, although the optimal symmetry-breaking structure does not significantly alter the light absorption range and bandgap width, it greatly suppresses the recombination of photogenerated electron–hole pairs, enhances the charge separation efficiency, and lowers the adsorption energy barrier of the O 2 molecule. This work provides a systematic research perspective on symmetry-breaking structures, and also offers new research ideas for the synthesis of advanced catalysts.

Polonium was a highly toxic and radioactive nuclide commonly detected in wastewater from spent fuel reprocessing and lead‑bismuth-cooled reactor systems, making its removal essential for nuclear safety. In this work, lanthanum-modified magnesium‑aluminum layered double oxide (La-MgAl-LDO) was prepared by doping La(III) in Mg-Al layered double oxide (Mg-Al-LDO). Additionally, tellurium, which has similar chemical properties, was used as a substitute for polonium to investigate the adsorption performance. Under the optimized conditions (pH = 6, m/V = 0.2 g/L, and C 0 = 20 mg/L), La-MgAl-LDO achieved a maximum removal efficiency of 99% for tellurite. The adsorption of Te(IV) onto La-MgAl-LDO followed the pseudo-second-order and Freundlich models, indicating that the adsorption process was characterized by multilayer chemical adsorption. The Te(IV) adsorption mechanisms mainly include co-precipitation and surface complexation. In addition, the study confirmed that La 3+ reacted with Te(IV) to form a stable solid precipitate (La 2 Te 6 O 15 ), which played a crucial role in the removal of Te(IV) from aqueous solution.

In this study, the polysulfide-intercalated Mg/Al hydrotalcite (Mg/Al-S 2 -LDH) with nanometer scale was prepared by a facile intercalation reaction to remove uranyl (VI) from aqueous solution. The as-synthesized adsorbents were characterized by a variety of techniques such as XRD, SEM, EDS, FTIR, laser particle size analyzer and XPS. Results indicated that the alkali content (governed by the HMT/Al molar ratio parameter f) significantly influenced the particle size, rather than the morphology, of the Mg/Al hydrotalcite. The particle size decreased from 9.37 μm to 0.91 μm with increasing f value. Batch experiment results indicated that Mg/Al-S 2 -LDH adsorbent prepared at f = 3 exhibited the excellent removal performance for uranyl (VI) with the removal rate approaching 100% and a maximum adsorption capacity of 343.64 mg·g −1 . The adsorption process followed the pseudo-second-order model, and the adsorption thermodynamics conformed to Langmuir isotherm adsorption model, indicating that the adsorption process was primarily chemical adsorption and monolayer adsorption. The adsorption mechanism revealed that uranyl (VI) ions were removed by the UO 2 2+ forms inner-sphere complexes with interlayer S 2 2− groups and the formation of an amorphous UO 2 S 2 -like phase on the surface. In addition, results from competitive adsorption suggested that Mg/Al-S 2 -LDH adsorbent processed excellent affinity to uranyl (VI) in the co-exist ions of Na + , K + , Ca 2+ , Mg 2+ , which revealed a potential application prospect in the treatment of U(VI)-contaminated wastewater.

Abstract Manganese-based oxides are attractive cathode materials for aqueous magnesium-ion batteries (AMIBs) due to their high theoretical capacity, abundant resources, and environmental friendliness but suffer from poor conductivity, manganese dissolution, and structural degradation during cycling. In this work, CuMn2O4 is proposed as a dual redox-active cathode material for AMIBs. During discharge, lattice copper ions are extracted and in-situ reduced to metallic copper, which contributes to capacity and enhances electronic conductivity. Consequently, CuMn2O4 delivers highly enhanced capacity (211 mAh g−1 at 100 mA g−1) and cycling stability compared to monometallic Mn3O4. Moreover, the aqueous Mg∥CuMn2O4 full cell achieves an average discharge voltage of 1.80 V and stable cycling for over 50 cycles. This study confirms the feasibility of CuMn2O4 as a high-performance cathode material for AMIBs and provides insights for developing low-cost, high-performance multivalent-ion battery cathode materials.
