Mg metal anodes experience significant passivation of harmful side reactions in conventional electrolyte consisting of magnesium bis(trifluoromethane sulfonyl)imide (Mg(TFSI) 2 ) in 1,2-dimethoxyethane (DME), which critically impedes the advancement of high-performance rechargeable magnesium batteries. Herein, an innovative electrolyte system comprising an ultra-dilute 0.02 M Mg(TFSI) 2 in DME with 4-chlorobutyl methyl ether (CME) as co-solvent is strategically devised. This unique formulation effectively suppresses the formation of TFSI − -derived passivation byproducts while simultaneously facilitating the establishment of protective Cl-rich interphase, thereby achieving exceptional reversibility in Mg plating/stripping processes. Remarkably, Mg electrodes demonstrate stable cycling performance with a minimal overpotential of 70 mV at 0.1 mA cm −2 in the optimized 0.02 M Mg(TFSI) 2 -DME/CME electrolyte. More impressively, the system maintains reversible electrochemical operation for 400 h even at 2 mA cm −2 . This work presents a novel electrolyte formulation for overcoming the limitations of Mg metal anode in conventional Mg(TFSI) 2 based electrolytes, offering new perspectives for the development of next-generation rechargeable magnesium batteries.

Bone pain is the primary problem for patients with osteoporosis. Ketoprofen is clinically used to treat osteoporotic pain, while long-term oral administration of ketoprofen can cause some side effects. In addition, osteoporosis is also accompanied by bone mass loss and inflammation. In this study, we designed a multifunctional drug (Ket@Mg-MOF-74) adopted Mg-MOF-74 to load ketoprofen to treat osteoporotic pain, bone loss and inflammation comprehensively. Mg-MOF-74 was prepared, and the physicochemical characterization proved that it had excellent physical and chemical stability. Ket@Mg-MOF-74 was synthesized by post-synthetic modification method and a high loading rate of ketoprofen was confirmed. Drug release and ion release experiments indicated Ket@Mg-MOF-74 had a good controlled release of ketoprofen and Mg in solution. Cell experiments in vitro proved the compound drug could significantly reduce the expression of pain-related genes of cyclooxygenase 2 (COX2), obviously up-regulated the expression of osteogenic cytokines and remarkably down-regulated the secretion of pro-inflammatory factors. Therefore, Ket@Mg-MOF-74 is believed a promising painkiller for osteoporotic bone pain, with the function of anti-inflammatory and promoting bone formation.

Mg doped (Ba 0.98 Li 0.02 )TiO 3 energy storage ceramics with antiferroelectric-like double hysteresis loops were prepared using solid-state reaction method. XRD patterns indicated that tetragonal phase structure of the pure (Ba 0.98 Li 0.02 )TiO 3 ceramic was destroyed and the orthorhombic phase structure appeared with Mg doping. The ratio of orthorhombic/tetragonal phase increased with Mg content increasing, and the value of polarization was in direct proportion to the ratio of orthorhombic/tetragonal phase. The breakdown strength of (Ba 0.98 Li 0.02 )(Mg x Ti 1− x )O 3 ceramics was improved from 60.97 kV/cm at x = 0 to 103.66 kV/cm at x = 0.04. The optimum energy storage properties of (Ba 0.98 Li 0.02 )(Mg x Ti 1− x )O 3 ceramics were obtained with energy storage density of 0.76 J/cm 3 at 102.5 kV/cm when x = 0.04, which is nearly 2.3 times larger than the pure (Ba 0.98 Li 0.02 )TiO 3 ceramic, and the energy storage efficiency was improved from 64 to 87%.

Cu-Mg-Al layered double hydroxides (LDHs) with amine modification were prepared by an organic combination of an anionic surfactant-mediated method and an ultrasonic spalling method usingN-aminoethyl-γ-aminopropyltrimethoxysilane as a grafting agent. The materials were characterized by elemental analysis, XRD, SEM, FTIR, TGA, and XPS. The effects of the Cu2+content on the surface morphology and the CO2adsorption of Cu-Mg-Al LDHs were investigated, and the kinetics of the CO2adsorption and the photocatalytic reduction of CO2were further analyzed. The results indicated that the amine-modified method and appropriate Cu2+contents can improve the surface morphology, the increase amine loading and the free-amino functional groups of the materials, which were beneficial to CO2capture and adsorption. The CO2adsorption capacity of Cu-Mg-Al N was 1.82 mmol·g−1at 30 °C and a 0.1 MPa pure CO2atmosphere. The kinetic model confirmed that CO2adsorption was governed by both the physical and chemical adsorption, which could be enhanced with the increase of the Cu2+content. The chemical adsorption was suppressed, when the Cu2+content was too high. Cu-Mg-Al N can photocatalytically reduce CO2to methanol with Cu2+as an active site, which can significantly improve the CO2adsorption and photocatalytic conversion.

Here, we report a new liquid-membrane electrodialysis capable of selectively recovering lithium from high Mg/Li ratio brines. The liquid membrane is composed of an ionic liquid system as the Li + carrier that presents high selectivity toward Li + and long-term sustainability, and 2 solid cation-exchange membranes to sandwich the carrier. Recognition and selective electromigration of Li + can be achieved by the sandwiched liquid membrane assisted by an electric field. The Mg/Li decreases from 50:1 in the initial feeding brine to 0.5:1 in the receiving solution after electrodialysis at a current density of 4.375 A·m − 2 for 12 h. Moreover, higher current efficiency (65%) and lower specific energy consumption (16 Wh·g − 1 Li) are obtained compared to typical electrodialysis processes. From the perspective of practical application, the Mg/Li drops to 0.26:1 from 53:1 in the old brine from West Taijinair, and K + and Ca 2+ in the brine are almost completely blocked by the liquid membrane. This method displays a great perspective on the application for lithium recovery from high Mg/Li brines owing to its high selectivity, efficient energy utilization, and environmental friendliness.

Hydrogen assisted magnesiothermic reduction (HAMR) of TiO 2 is a promising new process developed recently to produce Ti metal with low cost and less energy consumption. This work focuses on the understanding and optimization of the reduction process to control the quality of the reduced product. TiO 2 precursor particles with different relative densities were prepared, and the effects of the relative densities on reduction by Mg in H 2 were studied. The changes of oxygen contents vs. reduction time at various temperatures were investigated. The phase transformations during the reduction were analyzed both theoretically and experimentally. The relationship between the morphology of the reduced products and the relative densities of the TiO 2 precursors was analyzed by SEM characterization and the likely reason for the morphology evolution was discussed.

With a light absorption up to 740 nm, BaNbO 2 N is promising for solar water splitting but normally owns a low activity due to a high defect concentration. Here, Mg is adopted as a dopant to modify the BaNbO 2 N. The presence of Mg not only reduces the defect concentration and enhances surface hydrophilicity but also tunes the bandgap as well as the band edge positions. These modifications greatly promote the charge separation and transfer of BaNbO 2 N, boosting the photocatalytic activities for O 2 -evolution reactions. An apparent quantum efficiency of 1.65 % at 420 ± 20 nm has been attained for Mg modified BaNbO 2 N. Overall water splitting at a stable gas-evolution rate (∼ 2.0 μmol·h −1 for H 2 and ∼ 1.0 μmol·h −1 for O 2 ) has been realized by integrating Mg-modified BaNbO 2 N into a Z-scheme system. These findings justify Mg as an effective dopant to modulate the photocatalytic behavior of Nb-based perovskite oxynitrides.

Adsorption is a widely applied waste water treatment technology , especially for removing micro-pollutants and dyes of industrial effluents . Over the past decade, adsorbing metal oxide micron- and nano-particles have been successfully developed and investigated as adsorbents. In the present research, Mg-ferrite adsorbent particles were synthesized and their properties were fully determined. The pore volume is 0.139 cm 3 /g. The BET analysis reveals a surface area of 94.4 m 2 /g. The porosity is of meso- and microporous nature. The adsorbent was used to adsorb acid fuchsine, an important industrial dye. The equilibrium adsorption capacity was 796.4 mg/g, with an adsorption yield of 78.7–82.0%. The adsorption kinetics can be adequately fitted by a pseudo-second-order model. The isotherms of both Langmuir and Freundlich are applicable. The stability, recovery and reuse of the ferrite particles were proven in multi-cycle experiments, and the adsorption activity decreased by less than 3% between the first and fifth cycle. Experimental and fitting results were finally used to design a batch adsorber to remove a given concentration of acid fuchsine from different volumes of wastewater.

The mechanism of the interaction between nano-Mg(OH)2 adsorbent and uranyl in water was studied. At trace levels, the uranyl is adsorbed as a monolayer on nano-Mg(OH)2, and occupied a small proportion of the adsorption sites. As the uranyl concentration crosses over a threshold, continuous increase of adsorption capacity takes place. It indicates that, by taking the pre-adsorbed uranyl as the nucleation centers, the additional uranyl crystallizes and forms U-rich nanocrystals well-scattered on the surface of nano-Mg(OH)2. A strategy of inducing fast crystal growth of nano-Mg(OH)2 to micrometer-sized Na2Mg(CO3)2 enables the desorption and enrichment of uranyl. The recycling and reuse of nano-Mg(OH)2 can be achieved simultaneously. The finding in this work provides fundamental understanding of the efficient usage of nano-Mg(OH)2 in practical applications.

In this work, we reported an energy-saving and cost-efficient process for the (re)generation of NaBH4 by ball milling hydrated borax (Na2B4O7·10H2O) with a Mg–Al alloy under ambient conditions. The introduction of abundant and readily available Al can increase air stability of the reducing agent. A high yield up to 85.2% could be achieved by using Mg17Al12 because of its hardness and brittleness.

In this work, powder metallurgical (PM) Ti–Mg alloys were prepared using combined techniques of mechanical alloying and spark plasma sintering. The alloys mainly consist of super saturations of Mg in Ti matrix, and some laminar structured Ti- and Mg-rich phases. The PM Ti–Mg alloys contain a homogeneous mixtures of nanocrystalline Mg and Ti phases. The novel microstructures result in unconventional mechanical and biological properties. It has been shown that the PM Ti–Mg alloys have a much lower compression modulus (36–50 GPa) compared to other Ti alloys, but still remain a very high compressive strength (1500–1800 MPa). In addition, the PM Ti–Mg alloys show good biocompatibility and bioactivity. Mg can dissolve in the simulated body fluids, and induce the formation of the calcium phosphate layer. The compression modulus of PM Ti–Mg alloys decreases with the amount of Mg, while the bioactivity increases. Although the corrosion resistance of Ti–Mg alloys decreases with the content of Mg, the alloys still show good stability in simulated body fluid under electrochemical conditions. The indirect and direct cytotoxicity results show that PM Ti–Mg alloys have a good biocompatibility to NIH-3T3 cells. Therefore, the PM Ti–Mg alloys are promising candidates in biomedical applications.

For solid-state hydrogen storage, Mg(BH 4 ) 2 has long been recognized as a promising material. However, its higher thermal stability is distant from conditions for practical application. Herein, it is effectively established that VF 4 nanoparticles anchored on 2D Mxene Ti 3 C 2 (VF 4 @Ti 3 C 2 ) have efficiently catalytic effects towards the hydrogen storage process of Mg(BH 4 ) 2 . The MBH-VF 4 @Ti 3 C 2 sample started releasing hydrogen at 90 °C, which was 182 °C and 55 °C lower than those of additive-free Mg(BH 4 ) 2 and MBH-20Ti 3 C 2 composites. Additionally, the MBH-20VF 4 @Ti 3 C 2 composite desorbed more than 8 wt% H 2 at 275 °C. The activation energies of dehydrogenation were reduced, and the improved reversibility of VF 4 @Ti 3 C 2 -doped Mg(BH 4 ) 2 was also discussed. According to microstructural study, the heterostructural VF 4 @Ti 3 C 2 interacted with Mg(BH 4 ) 2 to produce VH 2.01 and metallic Ti during re/dehydrogenation, which worked as active species to improve hydrogen storage performance in Mg(BH 4 ) 2 .
