The intrinsic three-layer liquid architecture of liquid metal batteries (LMBs) enables a simple cell configuration, high safety, low projected cost, and exceptional theoretical cycle life, making them a promising technology for grid-scale energy storage. However, under high-temperature and multi-physics operating conditions, the corrosion of the stainless steel positive current collector (PCC) by molten cathode metal and halide electrolyte limits long-term durability. A systematic evaluation of commercially available stainless steels under realistic electrochemical, thermal, and chemical conditions is therefore essential. Herein, we investigate the corrosion behaviors of four representative stainless steels (SS201, SS304, SS316, SS430) used as PCCs in Li|LiCl-LiF-LiBr|Bi liquid metal batteries through a two-stage approach combining high-temperature hanging-coupon screening and service-condition cell testing. The results reveal pronounced synergistic corrosion during battery operation, where the combined effects of molten Bi , molten salt electrolyte, and electrochemical polarization substantially accelerate PCC degradation compared to static exposure. Among the investigated materials, SS316 exhibits the highest corrosion resistance, enabling stable cycling without observable capacity decay over 100 cycles. By integrating corrosion resistance, electrochemical performance, and techno-economic considerations, this work establishes an engineering-oriented PCC selection framework and identifies SS316 as the optimal candidate for 200 Ah-scale LMBs, allowing thinner, lighter, and more cost-effective collector architectures. The elucidated corrosion mechanisms under coupled electrochemical, thermal, and flow conditions provide critical insights for the rational design of durable and commercially viable liquid metal batteries.

A green ternary solvent system (Na 2 SO 3 /LiCl/urea) is developed to overcome the poor water solubility of wheat gluten. • Self-helical wheat gluten fibers are continuously fabricated via a one-step wet-spinning process. • The fibers exhibit excellent stretchability (1200% elongation), ionic conductivity, and excellent anti-freezing performance down to −80 °C. • The fibers enable real-time monitoring of human motions, respiratory behaviors, and Morse-code-based information transmission. • A smart glove system is demonstrated for closed-loop human-machine interaction using the helical fibers. With the rapid advancement of wearable intelligent electronics, various high-performance conductive fibers have been developed. However, most of them suffer from an inherent trade-off between electrical stability and mechanical deformability, often failing to maintain consistent conductivity under large or repeated mechanical strain. Inspired by natural helical architectures, wheat gluten (WG) conductive fibers with a self-helical architecture have been successfully developed via a facile wet-spinning technique. To address the intrinsically poor water solubility of pristine WG, a ternary solvent system consisting of Na 2 SO 3 , LiCl, and urea is developed. Continuous self-helical WG fibers are obtained by extruding the spinning dope into a 20 wt% Na 2 SO 4 coagulation bath. The resultant fibers exhibit exceptional mechanical flexibility (with an elongation at break of 1211 ± 85% and a tensile strength of 12.8 ± 1.5 MPa), outstanding anti-freezing performance (stable performance at −80 °C), ionic conductivity (1.59 ± 0.25 mS/m) and distinct humidity-responsive behavior. When assembled into flexible sensors, they enable reliable real-time monitoring of diverse human motions, subtle respiratory signals, and efficient human-machine interactions. Thus, this work provides a green, scalable, and straightforward approach for fabricating self-helical WG conductive fibers, which hold great promise for plant protein-derived wearable electronics in healthcare monitoring and human-machine interfacing applications.

Hydrogen plays a vital role in zero-carbon energy systems and lithium-ion battery health monitoring, while its safe utilization faces a critical challenge in achieving high-accuracy room-temperature detection with fast response speed. Herein, Ti 3 C 2 T x ternary composites decorated with Pd and SnO 2 nanoparticles (MPS) are successfully synthesized via a facile approach at 80 ˚C with a high hydrogen sensitivity based on a synergetic effect. Within the MPS composites, the dissociation energy barrier for hydrogen molecules can be drastically reduced with the existence of Pd nanoparticles, boosting the ionization of active hydrogen atoms at the heterointerface between SnO 2 and MXene via the hydrogen spillover effect. The isomorphous substitution of Ti 3+ by Sn 4+ generates abundant holes at the heterointerface, and the built-in electric field formed at the heterointerface subsequently promotes the recombination of these holes with the electrons generated during hydrogen ionization. Benefitting from the series of reaction, the optimal response of 73.5% is obtained with fast response/recovery time of 47 s/36 s upon exposure to 200 ppm H 2 at room-temperature. In addition, an outstanding linearity (R 2 =0.9908) is achieved within a range between 5 and 200 ppm, resulting in a superior LOD of 1.96 ppm. The MPS composite gas sensor simultaneously exhibits exceptional selectivity and cycling stability, shedding light on the new perspective of high-performance room-temperature gas sensing.

Water shortages in distant and dry areas require sustainable measures. An alternative composite hydrogel, which is extremely effective in solar-powered atmospheric water harvesting, is proposed in this research. Its synthesis was performed using radial polymerization. Based on polyacrylamide (PAM), hydroxypropyl cellulose (HPC) was incorporated to increase hydrophilicity. Lithium chloride (LiCl) was used as a humectant, and carboxylated carbon nanotubes (CNT-COOH) were used as photothermal nanofillers. The formulation of the optimized hydrogel (PAM-HPC0.3-CNT3.5-LiCl25) shows a high capacity of water absorption of 2.52 g g–1 at 90% RH and 25 °C and has the ability to achieve 90% saturation in 2 h at 40% RH. The hydrogel surface temperature under exposure to simulated sunlight (1.0 kW m–2) is 48.4 °C and allows desorbing approximately 96% of water in 10 h. It is also shown that the material has good cyclic stability after 10 adsorption–desorption cycles. Experimental testing outdoors proves its technical feasibility to collect atmospheric water on natural light. This paper offers a promising and energy-saving approach to materials to harvest water in areas with plentiful sunlight.

Fast charging and low-temperature operation are essential for next-generation energy storage. However, high-energy batteries struggle to meet these demands as existing electrolytes cannot simultaneously deliver fast interfacial kinetics, high ionic conductivity and favourable interphase formation. Prevailing strategies focus on weakening thermodynamic solvation, yet this approach does not directly address the kinetic bottleneck, that is, the desolvation barrier governing interfacial charge transfer. Here we reveal that the desolvation kinetics are dictated by dynamic solvent exchange rather than thermodynamic solvation energy. Guided by this mechanistic insight, we have formulated an electrolyte in which two anions carry distinct anionic potentials: high-anionic-potential anions form contact ion pairs that accelerate solvation-exchange kinetics, while low-anionic-potential anions form solvent-separated ion pairs that sustain high bulk ionic conductivity. The electrolyte enables fast charging and low-temperature operation in high-loading lithium-ion batteries. The design principle was further validated in aqueous aluminium-ion electrochemical systems, underscoring its broader relevance to sustainable, resource-abundant battery chemistries beyond the lithium ion. Together, our findings establish a new electrolyte design paradigm that decouples interfacial and bulk transport properties and expands the design space of battery electrolyte systems.

Two simple Schiff bases PHMP( (E)-2- ((2-(9H-purin-6-yl)hydrazono)methyl)phenol) and PHMEP( (E)-2- ((2-(9H-purin-6-yl)hydrazono)methyl)-6-ethoxyphenol) were designed and synthesized based on 6-hydrazine-purine with salicylaldehyde and 3-ethoxy-salicylaldehyde, respectively. Among them, both PHMP and PHMEP exhibit significant “turn-on” response characteristics when coordinating with Zn 2+ ions in an EtOH/H 2 O buffer solution, demonstrating remarkable selectivity and sensitivity, accompanied by a noticeable color change. Initially, neither probe exhibited significant fluorescence. However, upon forming complexes with Zn 2+ , PHMP and PHMEP exhibit bright blue and green fluorescence responses, respectively. In contrast, the ethoxy modification in PHMEP alters its steric hindrance and electron cloud density, resulting in fluorescence signals with both superior selectivity and sensitivity compared with PHMP . Additionally, the newly formed complex PHMEP -Zn 2+ can serve as a selective “turn-off” fluorescence probe for Cu 2+ ions. Experimental data indicate that the detection limits of PHMP and PHMEP for Zn 2+ ions are 1.08 × 10 −8 M and 8.85 × 10 −9 M, respectively; the detection limit of PHMEP -Zn 2+ for Cu 2+ ions is 1.79 × 10 −8 M. Job's plot analysis, ESI-MS titration, and theoretical calculations confirmed that the stoichiometric ratio of the probes to the target ions is 1:1. Additionally, PHMP and PHMEP demonstrate broad potential applications in quantitative detection, being suitable for both tap water and convenient test strips.

The practical implementation of high-rate charging all-solid-state batteries (ASSBs) is severely hindered by sluggish Li-ion transport and persistent solid–solid interface degradation. In this work, we design a lithiophilic quaternary Li-Al-Si-Zn (ASZ@Li) alloy anode with a multiphase electron–ion co-conductive network (EICN) to overcome these critical limitations. When assembled with a LiNi0.9Co0.05Mn0.05O2 (Ni90) cathode, the resultant full cell achieves ultra-rapid charge–discharge within 72 s at 50 C, yielding a specific capacity of 105.6 mAh g–1 (57.9% of its 1 C capacity). Notably, the cell delivers outstanding cycling durability: it retains 80% of its initial capacity after 2,050 cycles at 20 C and 80% of its initial capacity even after 1460 cycles at 50 C. Even under a high areal loading of 30 mg cm–2 (6.73 mAh cm–2), the cell maintains 86% of its initial capacity after 520 cycles at 2 C, a critical metric for practical high-energy-density battery systems. Systematic experiments combined with first-principles calculations reveal the distinct roles of each phase in the ASZ@Li anode. LiAl domains ensure robust electronic percolation, LiZn phases promote uniform Li deposition and fast Li-ion transport, and Si-rich regions alleviate mechanical strain during cycling. This multiphase synergistic effect efficiently reduces interfacial impedance, enhances Li-ion diffusion kinetics, and stabilizes the electrode/electrolyte interface, paving the way for a robust, scalable anode design paradigm for high-rate ASSBs.

Background Approximately 30% of epilepsy patients develop pharmacoresistant epilepsy (PRE), characterized by persistent seizures refractory to antiseizure medications (ASMs). While neuroinflammation is implicated in both epileptogenesis and treatment failure, its precise temporal contribution remains unclear. This study aimed to delineate the distinct roles of acute versus chronic neuroinflammation in seizure susceptibility and the maintenance of drug resistance. Methods Male Sprague‐Dawley rats received acute inflammatory priming via systemic (intraperitoneal) or intracranial (hippocampal) lipopolysaccharide (LPS) administration prior to lithium‐pilocarpine‐induced status epilepticus (SE). Rats were subsequently classified as PRE or pharmacosensitive epilepsy (PSE) based on their response to two sequentially administered ASMs. Outcomes were assessed using video‐EEG monitoring, hippocampal cytokine profiling (IL‐6 and TNF‐α), histopathological analysis of neuronal damage, and peripheral inflammatory markers. Results Acute inflammatory priming significantly lowered the threshold for SE induction ( P < 0.05); however, it did not increase the proportion of PRE ( P > 0.05). In contrast, established PRE was characterized by sustained hippocampal neuroinflammation, with markedly elevated IL‐6 and TNF‐α levels compared to PSE and control groups, alongside severe neuronal loss. Conclusion These findings reveal a temporal dissociation in the roles of neuroinflammation: acute inflammation acts as a potent initiator of epileptogenesis, whereas chronic, sustained inflammation coincides with the drug‐resistant phenotype. This study refines the prevailing view of neuroinflammation from a static pathogenic factor to a dynamic, phase‐dependent modulator, supporting the rationale for stage‐targeted strategies in PRE. Notably, putative mechanisms linking inflammation to resistance, such as impaired efferocytosis, warrant future experimental validation.

A novel bis-quaternary ammonium salt was synthesized. • The bis-quaternary ammonium salt was used as an aqueous co-monomer to enhance the size sieving and charge exclusion effects of the nanofiltration membrane. • The Li + /Mg 2+ separation factor of the optimized membrane reached 73.3, which is 5.4 times that of the pristine membrane. Efficient separation of Li + and Mg 2+ from salt lakes is important for the application and recovery of lithium resources. In this work, a novel bis-quaternary ammonium salt (QTMPDA) was synthesized and utilized as a co-monomer in the polyethyleneimine aqueous solution for interfacial polymerization (IP), synergistically regulating the pore structure and surface charge of the nanofiltration membrane and improving its Li + /Mg 2+ separation performance. The QTMPDA monomer features a linear short-chain diamino structure, enabling it to participate in the IP, increase the crosslinking density of the polyamide network, and form a more concentrated pore size distribution, thereby enhancing the membrane's size sieving effect. Meanwhile, the two quaternary ammonium cations in QTMPDA can effectively increase the membrane surface electropositivity, strengthening the electrostatic repulsion of Mg 2+ . Relative to the unmodified membrane, the zeta potential of the optimized membrane was elevated from −5.9 mV to 20.2 mV at pH 7 and the MgCl 2 rejection was increased from 93.3% to 99.2%. Moreover, the membrane demonstrated an excellent Li + /Mg 2+ separation factor of 73.3 (mass ratio of Mg 2+ /Li + = 100). This work offers a novel approach for regulating IP process via functional aqueous co-monomers to optimize membrane structure and performance.

Cross-substrate counter diffusion (CSCD) between imidazole and Zn(II)-loaded polyamide (PA) layers is carried out to in-situ grow zeolitic imidazole framework-leaf (ZIF-L) particles and improve the nanofiltration (NF) performances of negatively charged NF membranes. To achieve uniform distribution of Zn(II) in the formed PA layer, Cyclen was used to complex Zn(II) precursors during the interface polymerization (IP) between piperazine (PIP) and trimesoyl chloride (TMC) to dissolve the Zn(II)/PIP precipitation in the aqueous phase. Results showed that the addition of Cyclen improved the uniform dispersion and firm combination of ZIF-L particles (PTs) in the PA layers, improving both the water permeance and salt rejection of the formed TFN NF membranes. Under optimal conditions, TFN-PC 0.10-0.15 /ZIF membrane achieves a Na 2 SO 4 rejection of 90.2-96.8%, a pure water permeance of 25.8-32.8 L·m -2 ·h -1 ·bar -1 , a NaCl/Na 2 SO 4 mixed salt separation factor of 9.0-29.8, and good anti-fouling and operational stability.

Here, spherical secondary polycrystalline aggregate (LNMO-PC), micron-sized primary particle (single-crystal morphology) (LNMO-SC-L), and submicron primary particle (single-crystal morphology) (LNMO-SC-S) LNMO were synthesized. Their structures, morphologies, and surface properties were characterized and electrochemical performance evaluated at room (25 °C)/high (55 °C) temperature and high rates. LNMO-SC-S exhibited the highest crystallinity, lowest Mn3+content, and minimal charge-transfer resistance. It showed superior cycling stability (93.3% retention at 1 C over 500 cycles), excellent rate capability (~20 mAh g−1at 20 C), and enhanced high-temperature performance. The submicron primary particles suppress grain-boundary degradation and Mn3+disproportionation, shortens Li+paths, and improves reaction kinetics.

Amoisture-enabled power generator integrating multiple stable asymmetric structures was constructed. • Hofmeister effect and ion occupation effect have been found synergistically enhanced the capability. • A peak power density of 10.5 μW·cm −2 with sustained discharge for 100 h have been achieved. • A portable power supply was fabricated that realizing stable power delivery. Inspired by the thermohaline-driven operation of ocean currents, this work developed an asymmetric hydrovoltaic energy generator (AHEG) with all-weather stable output capability by integrating multiple asymmetric structures to drive continuous water and ion migration. Materials characterization and testing confirmed the stable existence of multiple asymmetric structures within AHEG, including moisture asymmetry, temperature asymmetry, ion concentration asymmetry, and surface potential asymmetry. Benefiting from these asymmetric structures, AHEG achieved a power density of 10.5 μW cm −2 , self-charging capability, and 100-h stable discharge, outperforming most reported moisture-enabled generators. Theoretical calculations further confirmed the synergistic role of Hofmeister and ion occupation effects in boosting AHEG performance. Furthermore, a portable power supply constructed through simple integration could drive miniature devices, providing insights into the development of novel high-performance HEGs. Inspired by the operation of thermohaline-driven ocean currents, a hybrid moisture- enabled power generator integrating multiple asymmetric structures has been developed, with conductive substrate and polyelectrolyte constitute the basic power generation unit, while localized thermal management enabled by radiative cooling film and photothermal conversion capability of conductive substrate simulate the temperature variation patterns of the Earth's poles and equator, respectively, achieve a outperforming power density of 10.5 μW·cm −2 , with self-charging capability and 100-h stable discharge prefoemance.
