Porous hydroxyapatite (HAp) composite fibers functionalized with up-conversion (UC) luminescent and magnetic Na(Y/Gd)F4:Yb3+,Er3+ nanocrystals (NCs) have been fabricated via electrospinning. After transferring hydrophobic oleic acid-capped Na(Y/Gd)F4:Yb3+,Er3+ NCs into aqueous solution, these water-dispersible NCs were dispersed into precursor electrospun solution containing CTAB. Na(Y/Gd)F4:Yb3+,Er3+@HAp composite fibers were fabricated by the high temperature treatment of the electrospun Na(Y/Gd)F4:Yb3+,Er3+ NCs decorated precursor fibers. The biocompatibility test on MC 3T3-E1 cells using MTT assay shows that the HAp composite fibers have negligible cytotoxity, which reveals the HAp composite fibers could be a drug carrier for drug delivery. Because the contrast brightening is enhanced at increased concentrations of Gd3+, the HAp composite fibers can serve as T1 magnetic resonance imaging contrast agents. In addition, the composites uptaken by MC 3T3-E1 cells present the UC luminescent emission of Er3+ under the excitation of a 980 nm near-infrared laser. The above findings reveal Na(Y/Gd)F4:Yb3+,Er3+@HAp composite fibers have potential applications in drug storage/release and magnetic resonance/UC luminescence imaging.

As part of a series of studies, effects of Na + substitution on the thermal evolution of cesium-based geopolymers on heating were studied. A series of sodium-substituted cesium-based geopolymers, Cs (1− x ) Na x GPs (where x =0, 0.1, 0.2, 0.3, and 0.4), were prepared and treated at 1300°C for 2 hours to obtain the corresponding ceramic products. The thermal evolution process was disclosed by virtue of a variety of technical, including TG-DTA, thermal shrinkage, XRD analysis, SEM, and TEM investigation. The results indicated that unheated Cs (1− x ) Na x GPs was not completely amorphous after the substitution of Na + and the crystallinity of Cs (1− x ) Na x GPs gradually increased with the rise of sodium content. Meanwhile, the average particle sizes of Cs (1− x ) Na x GPs also increased evidently with increases in sodium substitution. The final product after heat treatment mainly consisted of pollucite (CsAlSi 2 O 6 ) and amorphous glass phase. The particle size of pollucite grain gradually decreased as more Cs + were replaced maybe owing to the role of Na + in the nucleation process of pollucite. Two forms of Na + present in the final products: A small portion was present in the pollucite grains due to Na + partial occupied the crystallographic sites of Cs + ; and the rest were present in the amorphous glass phase among the pollucite grains. The average coefficient of thermal expansion (CTE) of resulting Cs (1− x ) Na x GPs ceramics increased from 4.80×10 -6 K −1 ( x =0) to 7.26×10 −6 K −1 ( x =0.4) with increases in sodium substitution, which could be due to the amorphous glass phase had a relatively higher CTE than that of pollucite.

Transition-metal sulfide is considered to be an admirable transformational electrode material due to low cost, large specific capacity, and good reversibility in lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs). Herein, the reduced graphene oxide-wrapped open bimetallic sulfide (NiS2–Co3S4@rGO) nanocage, derived from nickel–cobalt Prussian blue, was obtained by two-step calcination. There are luxuriant pore structures in the nanocage composite with a specific surface area of 85.28 m2 g–1, which provides plentiful paths for rapid transmission of Li+/Na+ and alleviates the volume stress caused by insertion and extraction of alkali metal ions. The excellent interface combination of bimetallic sulfide wrapped in reduced graphene oxide improves the conductivity and overall performance of the battery. Thanks to the special interface engineering, the open NiS2–Co3S4@rGO nanocage composite displays rapid lithium storage properties with an average diffusion coefficient of 8.5 × 10–13 cm2 s–1. Moreover, after 300 cycles, the reversible capacity of the composite is 1113.2 mAh g–1 at 1 A g–1. In SIBs, the capacity of the open NiS2–Co3S4@rGO composite is 487.9 mAh g–1 when the current density is 5 A g–1. These preeminent performances demonstrate the enormous development prospects of bimetallic sulfide nanocage as anode material in LIBs and SIBs.

Layered transition metal oxides are commonly used as the cathode materials in sodium-ion batteries due to their low cost and easy manufacturing. However, the application is hindered by poor rate performance and complex phase transitions. To address these challenges, a new seven-component high-entropy layered oxide cathode material, O3-NaNi0.25Fe0.15Mn0.3Ti0.1Sn0.05Co0.05Li0.1O2 (HEO) has been developed. The entropy stabilization effect plays a crucial role in improving the performance of electrochemical systems and the stability of structures. The HEO exhibits a specific discharge capacity of 154.1 mA h g–1 at 0.1 C and 94.5 mA h g–1 at 7 C. In-situ and ex-situ XRD results demonstrate that the HEO effectively retards complex phase transitions. This work provides a high-entropy design for the storage materials with a high energy density. Meanwhile, it eliminates industry doubts about the performance of sodium ion layered oxide cathode materials.

Since the concept of hybrid Li/Na-ion batteries (HLNIBs) was proposed, many cathode materials with excellent performance and low cost have been studied. However, in HLNIBs, mixed cationic electrolyte is formed as Na + is extracted from the cathode, resulting in relatively complicated and unstable electrochemical performance, especially for the half-cell test with lithium metal as the anode. It is necessary to consider the tolerance of lithium metal counter electrode to sodium contamination in half-cell test with hybrid-ion electrolyte containing different cations. In this work, we have found that lithium metal electrodes in hybrid-ion electrolyte are unstable and Na + causes significant polarization. The polarization influences over potential and complex interface properties and thus reduces the accuracy of half-cell tests. To solve the problem, lithium difluoro(oxalato)borate (LiDFOB) with excellent film-forming properties was utilized as an additive of symmetrical batteries to form solid electrolyte interface (SEI) film. The adverse effect of Na + on the kinetics of hybrid-ion electrolyte was confirmed by regulating the SEI film on lithium metal electrode. The SEI film exhibits a selective effect on Li + and Na + and inhibits the interfacial transport of Na + , which significantly reduces the overpotential of the batteries and the interface migration impedance and also improves the stability of lithium counter electrode. Lithium metal with stable interfacial properties in the presence of LiDFOB is a reliable counter electrode that resists sodium contamination in half-cell test. Graphical abstract

High-capacity transition metal chalcogenides exhibit intrinsically low conductivity and ion transport efficiency when applied to sodium-ion energy storage devices. Here, carbon-encapsulated WS x precursors are synthesized using high chloride hydrolysis properties combined with a hydrothermal process. Afterwards, WSSe 2 /C anode with dual anion effect is prepared by replacing some S atoms in WS x with Se atoms employing a microwave sintering process. The obtained WSSe 2 /C electrode exhibits a significantly enlarged crystal spacing by constructing built-in electric fields, which ensures rapid and stable Na + transport. The carbon-encapsulated strategy aims to improve electrical conductivity while providing a buffer medium for volume expansion during electrochemical phase transitions. Additionally, by exploring the effects of different carbon introductions on the electrochemical properties , it is determined that 1 g ribose encapsulated WSSe 2 (WSSe 2 /C-1) provides the best intervening effect. Consequently, in the assembled Na half-cell, the WSSe 2 /C-1 anode displays a high specific capacity of 715.3 mA h g −1 after 200 cycles of activation at 1 A g −1 . Further, the assembled sodium-ion capacitor exhibits a high-capacity retention of 86.5 % after 13,000 cycles at a high-power density of 3800 W kg −1 . This strategy of combining carbon encapsulation and dual anion effect provides a reference for developing high-power density anodes.

The solid–liquid phase equilibria of the Li+, Na+, Ca2+//Cl––H2O quaternary system at 298.15 and 323.15 K are studied via the isothermal solubility phase equilibrium method. The solubility data and liquid properties of density and pH are obtained. The phase diagrams of the quaternary systems, including the water free diagram, the water diagram, and the dry salt diagram, are plotted to show the phase regions, water content, and salting-in effect. NaCl occupies the largest phase region at both 298.15 and 323.15 K. One double salt LiCl·CaCl2·5H2O occurs at 298.15 K and builds up two invariant points; one incommensurate invariant point saturated by (NaCl, LiCl·H2O, LiCl·CaCl2·5H2O) and one commensurate invariant point saturated by (NaCl, CaCl2·4H2O, LiCl·CaCl2·5H2O), but at 323.15 K, no double salt forms. The salting-in effect that happened in ternary systems still occurs in the quaternary Li+, Na+, Ca2+// Cl––H2O system at both temperatures. NaCl saturated concentration increases with LiCl and CaCl2 contents and results in a very high total salt content at commensurate invariant points, e.g., they are 56.92 and 60.62% at 298.15 and 323.15 K, respectively.

Hyper cross-linked polymers (HCPs), as a key precursor of hard carbon (HC) anode materials, stand out because of their capacity for molecular-scale structural design and comparatively straightforward preparation techniques, which are not seen in other porous materials synthesized procedure. A novel synthesis method of HCPs is developed in this paper, which is through the incorporation of functional macromolecules , the structural control and heteroatom doping of the product has been achieved, thus augmenting its electrochemical performance in batteries. In this work, carbonized tetraphenylporphyrin zinc (TPP-Zn) doped HCP-based hard carbon (CTHCP) with stable structure was prepared by Friedel-Crafts reaction and carbonization by using naphthalene and trace TPP-Zn as monomers, dimethoxybenzene (DMB) as crosslinking agent and FeCl 3 as catalyst. The introduction of TPP-Zn, a functional macromolecule with unique two-dimensional structure, realized the pore structure regulation and N doping of the raw carbonized HCP-based hard carbon (CHCP). The results showed that CTHCP had higher mesoporous volume, N content and wider layer spacing than CHCP. In addition, CTHCP anode exhibited excellent Li + /Na + storage performance, initial reversible capacity, rate performance and long cycle life. More amount of N -containing (N-5) active sites and mesoporous content in CTHCP anode was the main reason for the improvement of Na + storage effect. While the increased interlayer spacing had a greater effect on the lithium storage capacity. This study uncovered the design rules of HC anode materials suitable for Li + /Na + batteries and provided a new idea for the preparation of high-performance HC anode materials.

p53 inactivation is a common feature in non-small cell lung cancer (NSCLC) resulting in NSCLC malignant transformation . Targeting serine 392 phosphorylation to restore p53 anticancer activity has proven to be an effective therapeutic strategy against NSCLC. A synthetic p53 activator, NA-17, has been developed that shows promise in preclinical models of NSCLC. However, NA-17 exhibits limited therapeutic efficacy in oncogene-driven tumors as well as relatively high toxicity to normal cells. It is possible that high efficiency and low toxicity p53 activators can be obtained by optimizing the leading molecule. Here, we performed high-throughput screening of compounds optimized based on NA-17 to identify new p53 activators. Two promising candidates named MX-C2 and MX-C3 were identified, both exhibited considerable therapeutic efficacy in oncogene-driven tumor models. Similar to NA-17, MX-C2/3 induced p53 activation via phosphorylating serine-392 without DNA damage. Both compounds showed broad antitumor activity in NSCLC cells and limited toxicity in normal cell lines. Moreover, MX-C2/3 suppressed tumor progression by arresting the cell cycle at G2/M phase, exhibiting a different mechanism of cell cycle arrest than NA-17. In addition, MX-C2/3 promoted the enrichment of p-p53 (s392) in mitochondria, leading to the conformational activation of Bak for cell apoptosis, which is consistent with NA-17. Finally, we demonstrated that MX-C2 significantly inhibited tumor growth without obvious systemic toxicity in oncogene-driven HCC-827 xenograft models. Collectively, we report two p53 activators with high-efficiency and low-toxicity that target p53 serine 392 phosphorylation for anticancer translational investigation.

The Metal-Organic Framework (MOF) materials are ideal molecular sieving membrane materials due to the regular pores with high-density and good designability, which have been widely studied in gas separation, desalination, and nanofiltration , etc. However, most preparation methods of MOF polycrystalline membranes are always time-consuming and the as-synthesized MOF membranes are thick. Here in this work, the ultrathin 210 nm-UiO-66 polycrystalline membranes are rapidly synthesized in 1 h, where sonication is utilized to generate massive tiny nucleation followed with rapid microwave-assisted membrane growth. The Na + rejection of the UiO-66 membrane maintains at 99.6% for 700 h long-term experiment with 0.16 L/(m 2 h bar) of water flux in forward osmosis, indicating the good quality and excellent stability of the as-synthesized membrane. This strategy is also expected to synthesize many other continuous defect-free MOF membranes with ultrathin thickness rapidly.

O3-type layered oxides are among the most promising cathode candidates for sodium-ion batteries, yet their practical use is constrained by irreversible oxygen redox at high voltages, parasitic side reactions, and pronounced moisture sensitivity. Here, we propose a one-step H 3 BO 3 treatment that introduces an in-situ boride complex, enabling near-surface B doping and the formation of a conformal sodium borate interphase. The dual modification operates synergistically: B incorporation reinforces the layered framework and suppresses oxygen redox above 4.0 V, while the sodium borate layer, endowed with high Na + conductivity, functions as a robust interfacial barrier. These effects collectively suppress transition-metal dissolution, mitigate electrolyte decomposition, and promote rapid Na + transport. Benefiting from this design, the optimized cathode delivers 160.5 mAh g -1 at 0.1C and retains 85.3% capacity after 200 cycles at 1C. Moreover, the sodium borate coating effectively blocks H + /H 2 O ingress, conferring exceptional air stability. After 150 cycles, 3-days-aged pristine cathode retains 4.7% of the fresh capacity, whereas optimized cathode maintains nearly pristine cycling stability. Even after seven days of exposure, only trace Na 2 CO 3 impurities are detected. This work establishes in situ boride complexes as a viable strategy to achieve electrochemically robust and moisture-tolerant sodium-ion cathodes for grid-scale energy storage.

Sodium-ion batteries are renowned for their abundant reserves, cost-efficiency, safety, and eco-friendliness and are prime candidates for large-scale energy storage applications. The development of cathode materials plays a crucial role in shaping both the commercialization path and the ultimate performance capabilities of SIBs. To overcome the intricate synthesis challenges associated with pure-phase sodium-ion cathode materials, this study introduces an innovative and streamlined electrochemical Li+/Na+exchange process, successfully fabricating a high-capacity Ni-rich cathode material. This cathode material boasts a remarkable reversible capacity of 180 mAh g−1at 0.1 C and retains a high-rate capacity of 115 mAh g−1even at 5 C. Additionally, it exhibits exceptional cycling stability, retaining about 85% of its capacity at 1 C after 50 cycles and still maintaining a capacity greater than 60% after 100 cycles. The Na-NMA85 full cell preserves a discharge capacity of 110 mAh g−1after 100 cycles, with a capacity retention rate of 80%. This research underscores innovative strategies for designing ion-intercalation-based cathode materials that enhance battery performance, providing fresh perspectives for advancing high-performance battery technologies.
