The aerospace, military stealth, and 5G communication fields have raised new requirements for multifunctional materials. In this study, a rigid MWCNT/Co@C/rGO/PMI composite foam (MCGP) was prepared using a UV light-initiated in-situ copolymerization hot air foaming method. The sandwich structure of MOF-GO-MOF, after calcination, achieved a uniform dispersion of magnetic Co particles and formed rich hetero interfaces. The 0D Co@C, 1D MWCNT, and 2D rGO formed a multi-dimensional filler system, and the magnetic-electrical synergy and isotropy bubble structure jointly optimized the impedance matching, and multiple loss mechanisms enhanced the absorbing performance. The results showed that M20C20/PMI achieved a RL value of -68.26 dB at a frequency of 8.92 GHz and a thickness of 40mm, and the EAB covered the full frequency band of 2—18 GHz. The RCS value of M25C15/PMI reached a minimum of -45.82 dB·m 2 . Notably, by carefully adjusting the proportion of fillers, the five MCGP composite foams prepared in this study all had a minimum RL value of < -55 dB, basically meeting the requirements of each absorption frequency band. In addition, the MCGP composite foams are lightweight (28.30 kg/m 3 ), have high strength (0.50 MPa), heat insulation (0.02856 W/(m·K)), and infrared stealth characteristics, making them promising as a new generation of integrated structural–functional protective materials.

Proton conducting ceramic cells enable efficient electrocatalytic H 2 -to-power conversion, yet their perovskite air electrodes demand versatile properties: high bulk proton uptake/conductivity, fast surface oxygen kinetics, and operational stability. Conventional single-phase perovskites usually fail to meet these demands simultaneously. Here, we show a facile strategy that couples bulk cation migration with surface segregation to enhance the versatility of the air electrode. The as-prepared (Ba 0.9 Ce 0.1-α )(Ce α Fe 0.8 Ni 0.2-β )O 3-δ -βNiO (cm-BCFN@NiO) electrode features a coupled bulk–surface architecture where finely dispersed NiO nanoparticles and Ce migration from A-sites to B-sites synergistically optimize surface oxygen kinetics, bulk proton uptake/conductivity, and electronic transport. The optimized electrode exhibits a low area-specific resistance of 0.3 Ω cm 2 at 550 °C—a 75% reduction compared to the NiO-free counterpart—enabling a 77.1% increase in maximum power density and over 1200 hours of stable single-cell operation. Beyond protonic ceramic cells, this work presents an approach for designing perovskites by leveraging cation migration and surface segregation at the atomic scale, opening more opportunities for a wide range of electrocatalytic applications.

Cryopreservation is essential for cell therapy and regenerative medicine, while macromolecular cryoprotectants play a crucial role in mitigating the freeze injuries caused by subzero temperatures. Physical damages induced by ice crystals and oxidative damages triggered by reactive oxygen species are two major types of injuries during cryopreservation. Herein, a series of selenium-containing block copolypeptides are synthesized from L-selenomethionine and N ′-Cbz-L-ornithine, which demonstrate ice-controlling properties in ice recrystallization inhibition, ice nucleation temperature, and ice crystal shaping. Owing to the significant antioxidant activities, these selenium-containing polypeptides can also effectively scavenge H 2 O 2 and alleviate the oxidative injury. In serum-free cryopreservation of L929 fibroblasts, the cryoprotectant consisting of selenium-containing polypeptides, 5% dimethyl sulfoxide (DMSO), and trehalose achieves over 80% post-thaw survival, maintaining normal proliferation superior to 10% DMSO and intact cellular integrity. This work provides a valuable insight into applications of selenium-containing polypeptides in cryopreservation of cells by reducing oxidative injuries and moderate ice-induced damages.

Developing multifunctional separators is essential for mitigating the polysulfide shuttle effect and unstable lithium deposition in lithium–sulfur (Li–S) batteries. In this work, a series of antiperovskite nitrides was synthesized via a hydrothermal nitridation–reduction method and coated onto polypropylene (PP) separators to fabricate composite membranes. Due to its abundant metallic active sites and high electronic conductivity, the ZnNNi 3 modification enables strong chemisorption and accelerated catalytic conversion of polysulfides. Simultaneously, it provides rapid Li + transport pathways that guide uniform Li plating and effectively suppress dendrite growth. Consequently, Li–S batteries with the ZnNNi 3 @PP separator retain 76.5% capacity after 100 cycles at 0.5 C and deliver 589.9 mAh g −1 at 3 C. At a high sulfur loading of 6.4 mg cm −2 , the ZnNNi 3 @PP achieves 910.5 mAh g −1 at 0.2 C and maintains 80.5% retention over 240 cycles with an ultralow fading rate of 0.08% per cycle. Li‖Li symmetric batteries further exhibit stable cycling for over 2000 h at 0.2 mA cm −2 , confirming that ZnNNi 3 @PP enables uniform lithium deposition. This antiperovskite nitride-based modification strategy represents a promising technical route for advancing high-performance Li–S batteries.

This study investigated the therapeutic potential and mechanism of Bushen Huoxue Acupuncture (BSHXA) against Alzheimer’s disease (AD) using integrated in vivo and in vitro approaches. In eight-month-old SAMP8 mice, BSHXA treatment significantly improved cognitive performance, alleviated hippocampal neuronal damage and neuroinflammation, and downregulated LAPTM5 expression. Complementary in vitro experiments in lipopolysaccharide (LPS)-stimulated BV2 microglia demonstrated that LAPTM5 knockdown reduced apoptosis, pathological protein accumulation, and pro-inflammatory M1 polarization. Through bioinformatic prediction and Co-IP assays, SMURF2 was identified as an E3 ubiquitin ligase directly interacting with LAPTM5 and promoting its ubiquitin-dependent degradation. SMURF2 overexpression in vitro reproduced protective effects similar to LAPTM5 knockdown. Importantly, in vivo knockdown of SMURF2 abolished the therapeutic benefits of BSHXA. Collectively, these findings demonstrate that BSHXA ameliorates AD progression by upregulating SMURF2, which promotes the ubiquitination and subsequent degradation of LAPTM5, thereby suppressing microglial M1 polarization, inhibiting neuroinflammatory responses, and attenuating AD pathologies. The SMURF2-LAPTM5 axis is established as a key mechanistic pathway underlying the neuroprotective effects of BSHXA. Graphical

As a typical endocrine disrupter, bisphenol A (BPA) could damage the reproductive and endocrine systems of humans and mammals. Therefore, the precise removal of BPA from the environment becomes increasing urgent. In this work, we employ Pickering emulsion polymerization to prepare the molecularly imprinted polymers (MIPs) microspheres through the non-covalent molecular imprinting strategy, which contain specific binding sites for the precise recognition of BPA. Graphite-carbon nitride (g-C 3 N 4 ) possesses a unique interfacial characteristic and is expected to develop potential application in the field of Pickering emulsion polymerization. In the process of polymerization, g-C 3 N 4 nanosheets are used as the sole emulsifier to build the Pickering oil/water emulsion system followed by the thermal-induced radical polymerization. The template molecules of BPA could be eluted from the polymer microspheres by continuous soxhlet extraction. The obtained MIPs microspheres were characterized with the help of optical microscope and field emission scanning electron microscope, respectively. The MIPs microspheres present regularly spherical structure with a relative broad size distribution. The formation of imprinted sites on the MIPs was validated through a batch of rebinding experiments, including the binding kinetics, binding isotherm, selective experiment and competitive experiment. The MIPs microspheres would have broad application prospect in environmental and analytical fields. Graphical abstract

An efficient synthesis method for the NbOFFIVE-1-Ni/calcium alginate aerogel composite was reported in this study. The composite material exhibited the combined beneficial properties of both aerogels and MOFs. Calcium alginate, as the carrier of NbOFFIVE-1-Ni, endowed the aerogel with excellent mechanical strength and a synergized macroporous structure with the microporous structure of NbOFFIVE-1-Ni, resulting in a significant synergistic effect. Moreover, the composites exhibited excellent structural properties, including favorable morphology and structure, intact crystal structure, superior thermal stability, mechanical strength, and good cycling stability. The CO 2 adsorption capacity of the aerogel reached 1 mmol/g at a CO 2 concentration of 3000 ppm and a temperature of 298 K. After ten cycles of adsorption and desorption, the efficiency remained stable, indicating the significant potential of the composite for fast uptake of low-concentration CO 2 .

Poly(phenylacetylene)s (PPAs) are one kind of important helical polymers with tunable main chain conformations. However, the preparation of near-infrared optically active helical PPAs remains a challenge. Here, we report a novel helical poly( m -terphenyl acetylene)s (PTPAs) bearing two chiral alkylamide pendants, which showed a stretched cis-transoid helix in solution or poly(methyl methacrylate) matrix with a broad optical activity range from the ultraviolet-visible (UV-Vis) to near-infrared regions. The effects of substituents, solvents, temperature, and acid/base additions on the helical conformation were carefully investigated. The substituent structure had little effect on the elongation but remarkably affected the main chain screw sense. The stability of this extended cis-transoid helix depends on the solvent applied and the temperature. Reversible conformational transitions between the one-handed cis-transoid helices and frustrated coil conformations can be achieved by the addition of trifluoroacetic acid and triethylamine. Furthermore, full-color circularly polarized luminescent materials can be prepared by virtue of their broad Cotton effects and chirality-selective absorption.

To establish the standardized processing technology of velvet antler stir-fried with Polygonatum sibiricum juice, elucidate the core mechanism underlying the enhanced anti-non-alcoholic fatty liver disease (NAFLD) efficacy of the processed product, and identify the key bioactive components. Taking protein content as the screening index, this study optimized the processing parameters of Polygonatum sibiricum -Prepared Cervus elaphus Velvet Antler (PC-PR) using single-factor experiments combined with response surface methodology (RSM). The in vivo pharmacodynamic efficacy was validated in a high-fat diet-induced NAFLD rat model. Multi-omics technologies were integrated to screen for core differential proteins enriched after processing. The in vitro activity of the target component was verified in an oleic acid-induced inflammatory model of HepG2 cells, and Western blot (WB) analysis was employed to decipher its molecular regulatory mechanism. A standardized processing technology for PC-PR was successfully established, which induced specific alterations in the compositional profile of velvet antler. The processed product significantly improved blood glucose, body weight, liver function, and lipid metabolism indicators in NAFLD model rats, with superior efficacy compared to non-optimally processed velvet antler. Multi-omics screening and in vitro experiments confirmed that Q28237 is a core bioactive component specifically enriched after processing, exhibiting potent lipid-lowering and anti-inflammatory activities. Mechanistic studies revealed that Q28237 alleviates the pathological progression of NAFLD by constructing a “component-pathway-phenotype” regulatory network, which involves inhibiting the overactivation of epidermal growth factor receptor (EGFR), promoting the activation of the phosphatidylinositol 3-kinase-protein kinase B (PI3K-AKT) pathway, and activating estrogen receptor1 (ESR1) to exert synergisticanti-inflammatory effects.

Pregabalin, a typical representative of pharmaceuticals and personal care products (PPCPs), has seen its environmental residue issue become increasingly prominent due to its widespread and high-volume clinical use. While its potential neurotoxic risks have attracted attention, the specific mechanisms underlying its induction of neurotoxicity have not yet been fully elucidated. This study investigated the neurotoxic effects of pregabalin using a zebrafish model: first, it predicted the potential mechanisms and key targets of pregabalin-induced neurotoxicity utilizing network toxicology techniques, followed by verification via experimental methods such as reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The results showed that pregabalin exposure binds to key receptors such as GRIA2, interferes with the glutamatergic synaptic pathway, thereby triggering neuronal apoptosis, and ultimately leading to neurodevelopmental impairment in zebrafish larvae — specifically a significant 8.8% reduction in neural axon length, accompanied by abnormal motor behavior, namely a significant 33.3% decrease in movement distance and a 33.4% decrease in movement speed, respectively. These findings not only provide key experimental evidence for the in-depth analysis of the neurotoxic effects and molecular mechanisms of environmental pregabalin exposure but also offer theoretical support for the systematic assessment of its eco-neurotoxic risks to ecosystems.

The weak light absorption, low charge separation efficiency, and poor recyclability severely restrict the practical application of heterogeneous photo-Fenton catalyst MIL-100(Fe). Herein, we report the synthesis of Fe 3 O 4 @MIL-100(Fe) with tunable structures via hydrothermal growth, using Fe(NO 3 ) 3 ·9H 2 O and H 3 btc as precursors on an Ag/Fe 3 O 4 template. Notably, Fe(NO 3 ) 3 ·9H 2 O serves dual roles: it acts as a precursor for MIL-100(Fe) formation and as an oxidizing agent to remove the Ag template. The microstructure of the resulting catalyst can be precisely regulated by varying the Fe 3⁺ dosage. By optimizing the Fe(NO 3 ) 3 ·9H 2 O dosage, the optimal hollow Fe 3 O 4 /MIL-100(Fe) catalyst is obtained, which exhibits excellent dispersion, a distinct core/shell structure, a larger specific surface area (312.6 m 2 /g), a smaller average pore diameter (4.9298 nm), strong magnetic separability, and superior photo-Fenton degradation performance (95.6% within 30 min). After 4 consecutive cycles, the degradation efficiency toward Rhodamine B (RhB) remains above 90%, demonstrating outstanding cycling stability. Electron spin resonance (ESR) analysis confirms that both ·O 2 ⁻ and ·OH are the dominant reactive oxygen species responsible for the catalytic degradation reactions.
