Solid-state lithium batteries (SSLBs) have attracted significant attention due to their high energy density and safety. However, the volumetric expansion/contraction of electrodes, along with persistent interfacial side reactions, leads to mechanical stress damage and failure of interfacial ion transport. Herein, we report an interfacial self-healing polymer electrolyte (SHPE) based on gradient covalent–noncovalent dynamic bonds, enabling multi-interfacial dynamic self-healing throughout the lifecycle of SSLBs. Via molecular engineering, high-strength boronic ester bonds are combined with ultrafast dynamic responsive hydrogen bonds to enable efficient room-temperature self-repair of interfacial defects in SSLBs. The rapid dynamic exchange between polymer chains further promoted fast lithium-ion conduction, achieving an ionic conductivity of 1.6 × 10 −3 S cm −1 (25°C). The Li|SHPE|Li cells demonstrated stable cycling for >3000 h. The incorporation of oxidation-resistant boron- and fluorine-containing functional groups extended the electrochemical window to 5.2 V. LiFePO 4 |SHPE|Li and LiCoO 2 (LCO)|SHPE|Li cells delivered >1000 and 700 cycles, respectively, while being compatible with LCO under high voltage (4.6 V) and loading (14 mg cm −2 ). Furthermore, the LCO|SHPE|Li (1.2 Ah) and LCO|SHPE|Si-C (2.5 Ah) pouch cells exhibited 200 and 400 cycles, respectively, and passed nail penetration safety tests. This study provides an interfacial self-healing strategy for developing high-energy-density and high-safety SSLBs.

Phase-pure MgP 2 O 6 and NiP 2 O 6 metaphosphate ceramics were synthesized via solid-state reaction. Both crystallize in a monoclinic C2/c structure, with NiP 2 O 6 exhibiting a contracted unit cell due to the smaller ionic radius of Ni 2+ compared to Mg 2+ . The optimum sintering temperature for MgP 2 O 6 was 975 °C, yielding ε r = 5.1, Q × f = 45,300 GHz, τ f = −14.7 ppm/°C, while for NiP 2 O 6 it was 925 °C, yielding ε r = 5.4, Q × f = 66,100 GHz, τ f = −8.7 ppm/°C. The slightly higher ε r of NiP 2 O 6 stems from higher bond ionicity and polarizability density. The superior Q × f is attributed to a higher packing fraction, larger lattice energies, and weaker phonon damping, as evidenced by a narrower Raman FWHM. The improved τ f arises from stronger A–O and P–O bond energies, resisting thermal vibrations. These results indicate MgP 2 O 6 and NiP 2 O 6 as promising low-permittivity microwave ceramics and suggest that A-site cation engineering provides a promising proof-of-concept for tailoring dielectric properties in metaphosphates.

The coexistence of oxyanion-type and cationic heavy metals in complex aqueous systems poses a significant challenge for adsorption-based remediation. Herein, mesoporous silica-supported manganese‑lanthanum mixed oxides (Mn x La 1-x @MCM-41) were synthesized via an oxidation-coprecipitation strategy. The mesoporous silica framework effectively confined amorphous Mn/La oxides, suppressing oxide aggregation and manganese leaching. The as-prepared Mn x La 1-x @MCM-41 materials exhibited efficient removal of heavy metals, with maximum adsorption capacities of 57.3 mg g −1 for As(V), 141.6 mg g −1 for Cd(II), and 333.0 mg g −1 for Pb(II). By adjusting the Mn/La molar ratio, the adsorption behavior toward different metal species could be systematically regulated, with La-enriched compositions favoring As(V) uptake and Mn-rich materials exhibiting enhanced affinity toward Cd(II) and Pb(II). High removal efficiencies for all three heavy metals were maintained under multicomponent coexisting conditions. The composition-dependent adsorption behavior reflects a functional differentiation of Mn- and La-associated surface sites, enabling the simultaneous immobilization of oxyanion and cationic contaminants. Overall, this work demonstrates that integrating mesoporous confinement with compositional regulation provides an effective strategy for constructing stable and multifunctional adsorbents for multicomponent heavy-metal remediation.

Albumin-based drug-delivery systems garner attention due to their inherent biocompatibility and tumor-targeting potential. However, they are limited by weak human serum albumin (HSA) affinity for drugs like camptothecin (CPT). To address this, we synthesize five CPT prodrug derivatives (CPT-SA-C6–C14) with tunable aliphatic alcohol chains as HSA-binding motifs and a succinic acid linker for carboxylesterase (CES1/CES2)-mediated cascade activation. CPT-SA-C10, C12, and C14 achieve ultrahigh drug loading (>30%) in albumin nanoparticles (ANPs) via enhanced HSA affinity. Aliphatic chain length shows an inverted V-shaped correlation with both HSA-binding affinity and CES1-catalyzed hydrolysis. The resulting intermediate is hydrolyzed by CES2 to release CPT. CPT-SA-C12 ANPs exhibit the highest albumin affinity and fastest enzymatic conversion, yielding superior therapeutic efficacy and favorable tolerability. This work elucidates the structure-activity relationship of albumin-bound prodrugs and advances the design of CES-responsive nanomedicines.

Against the background of carbon peaking and carbon neutrality goals, green hydrogen has become a clean and efficient energy carrier and a core driving force for energy transition. Water electrolysis accounts for 90% of green hydrogen production and serves as the key route for green hydrogen preparation. However, performance bottlenecks of conventional catalysts severely restrict the large-scale application of green hydrogen. High-entropy alloys, with their unique cocktail effect and lattice distortion, offer an approach to overcome this challenge and have emerged as a critical breakthrough in the green hydrogen field. This work systematically investigated the effect of vanadium content on the electrocatalytic performance of Fe 40− x (CoCrNiMn) 60 V x high-entropy alloys, focusing on the optimization of hydrogen evolution reaction (HER) activity, and aimed to develop non-noble metal bifunctional electrocatalysts suitable for both freshwater and seawater working conditions. The results showed that the Fe 39 (CoCrNiMn) 60 V 1 alloy exhibited excellent HER performance within the same system in 1 M KOH electrolyte at a current density of −10 mA cm −2 , with an HER overpotential of only 98.3 mV, which was superior to that of most non-noble metal catalysts. This alloy also delivered favorable oxygen evolution reaction (OER) activity with an OER overpotential of 291.7 mV, and no obvious performance decay occurred after a 30 h stability test. In alkaline seawater electrolyte, the alloy maintained stable HER activity, with the HER overpotential slightly increasing to 106.2 mV at an equivalent current density, and the OER overpotential reached 350 mV. In overall water splitting tests, the Fe 39 (CoCrNiMn) 60 V 1 alloy retained outstanding performance after 100 h of testing in both alkaline freshwater and alkaline seawater electrolytes, which fully demonstrated its great potential to replace noble metal catalysts and realize efficient hydrogen production from seawater. This work not only provided insights into the design of high-entropy alloy electrocatalysts but also was of great significance for enhancing HER performance, promoting large-scale green hydrogen production, and achieving efficient utilization of seawater resources.

Patients with sepsis exhibit circadian disruption and persistent immunosuppression. However, the molecular mechanisms linking them remain unclear. Integration of multi‐cohort transcriptomic and single‐cell datasets shows that circadian gene dysregulation in patients with sepsis and septic mice correlates with disease severity and immunosuppressive states, with monocytes/macrophages emerging as a principal affected population. Sustained endotoxin stimulation elevates the core clock repressor NR1D1 in macrophages, which occupies the Igf2bp2 promoter and suppresses its transcription. Loss of IGF2BP2 destabilizes the V‐ATPase subunit transcripts Atp6v1b2 and Atp6v0c through an m 6 A‐dependent mechanism, disrupting phagolysosomal acidification rhythms and pathogen clearance. siRNA‐mediated NR1D1 knockdown restores IGF2BP2 expression, circadian oscillations, and phagolysosomal function during the development of endotoxin tolerance. To achieve therapeutic delivery, we engineer hybrid membrane nanovesicles (siNR1D1@HM‐LNP) that reverse circadian and immune dysregulation in septic mice, enhance bacterial clearance, and markedly improve survival. These findings establish an NR1D1‐mediated circadian‐immune coupling mechanism and provide a therapeutic strategy for targeting sepsis‐induced immunosuppression. Sepsis disrupts immune‐cell rhythms and weakens bacterial clearance. Biomimetic nanovesicles combining erythrocyte and inflammation‐activated macrophage membranes deliver siNR1D1 to dysfunctional macrophages, restoring the NR1D1–IGF2BP2–V‐ATPase pathway, circadian regulation, phagolysosomal acidification, and antimicrobial defense. In mouse models of polymicrobial sepsis and secondary pneumonia, treatment improves immune balance and bacterial control, reduces organ injury, and increases survival.

The widespread use of antimony as a catalyst in the textile industry presents risks to ecosystems and human health. This study investigated the removal of Sb(V) using three iron-based coagulants —polymeric ferric sulfate (PFS), ferric chloride (FeCl 3 ), and ferrous sulfate (FeSO 4 )—via coagulation-sedimentation, and elucidates the coagulation mechanism by speciation analysis and characterization of precipitate. At a wastewater pH of 5–6, PFS and FeCl 3 achieved 96 % removal of 1.0 mg-Sb/L with a dosage of 12 mg-Fe/L, while FeSO 4 showed only 78 % removal, primarily due to the requisite oxidation step to Fe(III) before hydrolysis and precipitation. Phosphate ions, organic dyes and humic acids could compete with Sb(V), thereby reducing its removal efficiency. Sequential chemical extraction and instrumental characterization analysis revealed that the primary components of the precipitate were FeSbO 4 and Fe r SbO 4 (OH) 3r-3 when PFS or FeCl 3 was used as the coagulant. During Sb(V) removal process employing FeSO 4 coagulant, a large portion of Fe(II) underwent direct reaction with Sb(V) to form FeSb 2 O 6 , while the remaining fraction was oxidized to Fe(III) and generated FeSb 2 O 6 and Fe r SbO 4 (OH) 3r-3 via the Fe(III) reaction pathway. The removal of Sb(V) was mainly due to chemical precipitation (90 %) and hydrolysis adsorption (10 %). PFS coagulation is a promising method for removing Sb(V) from textile wastewater.

In the oxygen evolution reaction (OER), the lattice oxygen mechanism (LOM) has the potential to exceed the theoretical overpotential limit of approximately 370 mV associated with the traditional adsorbate evolution mechanism (AEM). Therefore, it is crucial to promote lattice oxygen involvement in the OER through careful design. We prepared a self-supported NiFeV hydroxide pre-catalyst electrode using a one-step electrochemical deposition method. Most of the V in the pre-catalyst dissolved during electrochemical activation, as confirmed by various ex situ and in situ characterization studies. The actual catalyst comprised V-doped FeOOH and NiOOH. Notably, significant oxygen vacancies were generated due to V element dissolution and leaching. The reconstructed catalyst can facilitate oxygen production via both the AEM and LOM, supported by theoretical calculations and experimental validation. It operates steadily for 750 hours at a current density of 50 mA cm−2, requiring only 200 mV and 253 mV overpotentials to achieve current densities of 10 mA cm−2 and 100 mA cm−2, respectively. This work elucidates the electrochemical reconstruction of V-containing hydroxides in alkaline media under anodic conditions while providing valuable insights into developing high-performance catalysts that involve the LOM.

Industrial electrolysis of water is one of the effective strategies for green hydrogen production in the future. Nevertheless, the large-scale applications of water electrolysis are still intractable issues hindered by the high overpotentials and inferior reaction kinetics on the anode. Herein, a facile one-step hydrothermal method was applied to in situ growth the Fe and V co-doped Ni 3 S 2 electrocatalyst on nickel foam substrate (Fe, V–Ni 3 S 2 /NF). In 1 M KOH electrolyte, the as-prepared Fe, V–Ni 3 S 2 /NF electrode exhibited an improved water oxidation activity with ultralow overpotentials of 253 and 370 mV to realize large current densities of 100 and 1000 mA/cm 2 , respectively. More importantly, the Fe, V–Ni 3 S 2 /NF electrode existed an activation process during 100 h chronopotentiometry testing period. Detailed characterizations revealed that elements of V and S in the electrocatalyst were oxidized and dissolved into the electrolyte, making the electrocatalyst undergo surface reconstruction and resulting in a faster kinetic reaction rate, thus leading to enhanced oxygen evolution reaction activities. Collectively, the resultant Fe, V–Ni 3 S 2 /NF in this work provides new cogitation towards design and synthesis of low-cost electrocatalyst with large current densities for water oxidation.

In this study, reduced graphene oxide (RGO) and different stabilizers (hexadecyltrimethylammonium bromide, starch, and carboxymethyl cellulose) were applied to simultaneously support and stabilize Fe-Mn binary oxide (FeMnO x ) nanohybrids, and enhanced removal of As(III)/(V) from water was achieved. TEM images shows that the aggregation of FeMnO x on RGO was effectively inhibited after the starch stabilization, meanwhile, the loading of FeMnO x on RGO was also increased. The adsorption capacity of As(III) and As(V) on starch-FeMnO x /RGO via Langmuir isotherm model was 78.74 mg g −1 and 55.56 mg g −1 , respectively, which was 1.99 and 2.39 times higher than bare FeMnO x . The adsorption kinetics was well fitted by the pseudo-second-order model. The effects of initial pH and coexisted anions were investigated. Over 90% of As(III) and As(V) could be removed by starch-FeMnO x /RGO during the five consecutive adsorption-desorption cycles. The results revealed the potential of the RGO supported and starch stabilized FeMnO x as an efficient adsorbent for arsenic removal from water.

LiCoO 2 plays a key role in energy storage devices due to its high energy density. And the volumetric energy density of LiCoO 2 cathode can be significantly improved by increasing the charging cut-off voltage to 4.6 V. However, the increase in resistance at the LiCoO 2 interface, and the damage to the LiCoO 2 from the outside to the inside by the HF generated that caused by the decomposition of the organic electrolyte and LiPF 6 under 4.6 V conditions are not conducive to structural stability during cycling. Here, it is shown that the decomposition of electrolyte and LiPF 6 is effectively mitigated by inhibiting the interfacial catalytic activity of LiCoO 2 using an atomically thin layer of MXenes as a interlayer. Density functional theory results suggest that the decomposition energy of LiPF 6 is 1.13 and 3.21 eV at the interface of LiCoO 2 and MXenes, respectively. Time of Flight Secondary Ion Mass Spectrometry results further indicate that the decomposition products of the organic electrolyte and LiPF 6 have a thinner thickness at the interface of MXenes (5 nm) than LiCoO 2 (10 nm). This study provides a new and universal strategy for stabilizing the cathode interface to support the development of high energy density lithium-ion batteries.

Fluoride solid-state electrolytes (SSEs) offer superior electrochemical stability, making them theoretically ideal for high-voltage all-solid-state batteries (ASSBs), but their low Li + conductivity hinders practical application. Here, we exploit the polyanion coordination strategy to develop a class of fluoride SSEs, Li x Ti(PO 4 ) x /3 F 4 , which exhibits high ionic conductivity and ultrahigh-voltage stability. Especially, Li 1.3 Ti(PO 4 ) 1.3/3 F 4 (1.16 × 10 −5 S cm −1 ) demonstrates a two-order-of-magnitude enhancement in Li + conductivity compared to analogous Li 2 TiF 6 . Combined experimental and theoretical analyses reveal that the high ionic conductivity of Li x Ti(PO 4 ) x /3 F 4 arises from weakened Li + -surrounding interactions and flexible network structures. Attractively, the exceptional ionic conductivity and ultrahigh-voltage stability of Li 1.3 Ti(PO 4 ) 1.3/3 F 4 enable a low-resistance and highly stable electrolyte-electrode interface, contributing to 91.6% capacity retention after 200 cycles for 5 V-class LiNi 0.5 Mn 1.5 O 4 -based ASSBs at 1 C and 30°C. The discoveries in this work open a new avenue for designing high-conductivity fluoride SSEs, paving the way for the application of high-voltage cathodes in high-energy-density ASSBs.
