Next-generation biomedical interfaces, including wearable sensors, implantable electronics, and patient-specific therapeutic systems, require skin-like elastomers that combine softness, stretchability, and conformal adaptability with clinical and environmental viability. Here, we report a supramolecular gelatin elastomer formed via glycerol-mediated hydrogen bonding, which reorganizes the molecular network into a non-crystalline, reprocessable matrix that supports in situ shaping and mild-condition processing. The elastomer exhibits tunable mechanical properties, thermal plasticity, and recyclability, while maintaining ambient stability. Incorporation of functional nanofillers, including silica, hydroxyapatite, bioactive glass, and halloysite nanotubes, further enhances mechanical robustness and interfacial compatibility, enabling customized structural designs and functional performance. Leveraging these tunable mechanical and interfacial properties, the gelatin elastomer also enables integration of conductive components for adaptive and in situ processable biomedical interfaces. As a proof of concept, the elastomer incorporates carbon nanotubes and NaCl to achieve high electrical conductivity and high-fidelity signal acquisition, enabling stable recording of electrocardiogram (ECG), electroencephalogram (EEG) signals, and compound muscle action potentials (CMAPs) in humans. This work establishes a reprocessable, sustainable, and human-evaluated elastomer platform that bridges natural polymer chemistry with functional device performance, advancing the clinical translation of soft bioelectronic and therapeutic interfaces.

Enhancing the lithium-ion diffusion and electronic conductivity of olivine-type LiMn 0.8 Fe 0.2 PO 4 cathode materials via solid-state synthesis is crucial for industrial application. In this study, a combination of high-energy grinding and solid-state synthesis was employed to systematically investigate the influence mechanisms of conventional grinding, single-stage high-energy grinding, and two-stage high-energy grinding regarding the electrochemical properties of LiMn 0.8 Fe 0.2 PO 4 . Electrochemical characterization revealed that the Mn 2+ /Mn 3+ redox pair contributed 72.99%, 77.31%, and 77.89% to the charge specific capacity under conventional grinding, single-stage high-energy grinding, and two-stage high-energy grinding, respectively. Correspondingly, the contribution rates to the discharge specific capacity were 55.44%, 75.48%, and 74.29%, with the corresponding specific capacity values being 39.37 mAh/g, 84.85 mAh/g, and 107.57 mAh/g, respectively. These results demonstrate that the high-energy grinding process significantly enhances the electrochemical activity of the Mn 2+ /Mn 3+ redox pair. Mechanistic analysis further indicated that two-stage high-energy grinding effectively reduces particle size, thereby improving lithium-ion diffusion kinetics and forming a uniform and continuous carbon conductive network that enhances electronic conductivity. This enables the discharge capacity of the Mn 2+ /Mn 3+ redox pair in LiMn 0.8 Fe 0.2 PO 4 to be fully exploited. Overall, this work provides valuable theoretical insights into the controllable solid synthesis and performance optimization of phosphate-based cathode materials.

Both boron nitride (BN) and metal-organic framework (MOF) are ideal nanofillers to enlarge corrosion resistance of coating due to their two-dimensional layered or porous structure with special physical-chemical property. However, the agglomeration and weak interaction with epoxy resin (EP) blocks their effects on enhancing anticorrosion performance of EP coatings. In this work, BN was hydroxylated and subsequently coated with polydopamine (PDA), then onto which cerium metal-organic frameworks (Ce-MOFs) was in-situ grown to get BNOH@PDA-Ce-MOFs. This technology not only ensures good dispersibility of BN and Ce-MOF, but strengthens their interaction with EP through PDA modified layer. BN uniformly dispersed in EP can elongate the diffusion path of corrosive media to enhance the barrier properties of the coating. Meanwhile, Ce-MOF can form a dense passivation layer composed of hydroxide and oxides of cerium to further protect the metal from corrosion. Therefore, the electrochemical impedance spectroscopy (EIS) measured |Z| 0.01 Hz value of BNOH@PDA-Ce-MOFs/EP coating only relatively decreased after 56 days, remaining three orders of magnitude higher than that of pure EP coatings. Moreover, the accelerated salt spray test of 28 days, there are no obvious corrosion pits, confirming the excellent corrosion resistance of BNOH@PDA-Ce-MOFs/EP coating.

To adjust and optimize the structure and characteristics of biodegradable poly (butylene succinate) (PBS)-type polyesters, seven aliphatic polyesters with different chain lengths were synthesized by introducing azelaic acid. It can be finded that the melting points of the six polyesters gradually rise with increasing carbon chain length, with the exception of poly(propylene azelate) (PPAz). The XRD analysis reveals that the odd–even effect exerts a certain influence on the diffraction peaks. Specifically, the diffraction angles of odd-odd carbon polyesters demonstrate a systematic shift in comparison to those of odd–even carbon polyesters. Except for PPAz and poly(hexylene azelate) (PHAz), the hydrophilicity of the polyesters decreases with increasing chain length, with PHAz being the most hydrophilic polyester. The thermal decomposition temperatures of the seven polyesters exceed 315.0 °C, indicating good thermal stability. Among them, poly(decylene azelate) (PDAz) exhibits the highest thermal decomposition temperature, reaching as high as 358.1 °C. Enzyme hydrolysis studies show that poly(pentylene azelate) (PPeAz) has the best biodegradability, with the polyester experiencing 100% weight loss after 12 h of enzymatic degradation. Graphical

Magnetically recoverable polymer adsorbents have attracted considerable attention for dye wastewater treatment, however, the relationship between polymer-shell loading, accessible functional-group density, and charge-selective adsorption remains insufficiently understood. Herein, a series of carboxyl-functionalized magnetic polymer microspheres (CMPs) with tunable polymer-shell contents were prepared by precipitation polymerization using Fe 3 O 4 microspheres as magnetic cores and acrylic acid/ethylene glycol dimethacrylate as shell-forming monomers. Structural characterization demonstrated that increasing the acrylic acid feed progressively increased the polymer-shell thickness and surface carboxyl density, suggesting reduced accessibility because of increased swelling and decreased surface area. Consequently, CMPs-4 exhibited the optimal balance between functional-group density and accessibility. Under the optimized conditions, CMPs-4 showed excellent charge selectivity, exhibiting negligible adsorption toward the anionic dyes methyl orange and tartrazine, while achieving adsorption capacities of 250 mg·g −1 for methylene blue and 507 mg·g −1 for methyl violet. The adsorption followed a pseudo-second-order kinetic model and was well described by the Langmuir isotherm, indicating monolayer adsorption on homogeneous active sites. Salt-enhanced adsorption was attributed to the combined effects of polymer-shell contraction and dye aggregation under high ionic strength. FT-IR, XPS, zeta-potential measurements, and elemental mapping confirmed that adsorption was mainly governed by electrostatic interactions between surface carboxyl groups and cationic dyes, accompanied by hydrophobic and π-π interactions. Furthermore, CMPs exhibited excellent magnetic recoverability, regeneration stability, low Fe leaching, and effective dye removal from real textile wastewater. This work establishes a clear structure–property relationship between polymer-shell architecture and adsorption performance, providing a rational strategy for designing recyclable magnetic adsorbents for selective dye removal.

A novel aptasensor for the detection of aflatoxin M1 (AFM1) was developed based on the fluorescence resonance energy transfer (FRET) effect between gold nanoparticles (AuNPs) and FAM-labeled cDNA (FAM-cDNA). Additionally, magnetic nanoparticles (Fe 3 O 4 NPs) were attached with AuNPs to construct a Fe 3 O 4 @AuNPs system that was easy to separate by the external magnetic field. In this aptasensor, FAM-labeled cDNA and Fe 3 O 4 @AuNPs acted as donor and acceptor, respectively. In the presence of target AFM1, the aptamer of this aptasensor specifically recognized with AFM1, resulting in a turn-on fluorescence signal due to target-induced dissociation of FAM-cDNA from the FRET pair. The morphology, size and functional group of Fe 3 O 4 @AuNPs were characterized by TEM, XRD and FT-IR. The UV-vis absorption spectroscopy and fluorescence spectroscopy were used to determine the construction of Fe 3 O 4 @AuNPs@Apt@FAM-cDNA aptasensor. Under optimal conditions, the linear concentration range of 1-100 ng/mL, limit of detection (LOD) of 0.20 ng/mL, and recoveries of 99%~101% of the aptasensor were obtained. Overall, this aptasensor with satisfied sensitivity and selectivity are promising to be applied in the detection of other biochemical analytes in the future. Graphical

Poly(lactic acid) (PLA) is a renewable polyester material with excellent properties, such as processability, biocompatibility, and biodegradability, and is widely used in packaging and medical applications. However, neat PLA has the performance limitations of high brittleness and poor toughness, strongly restricting its practical use. In this study, three poly(ethylene glycol) (PEG)-based telechelic polymers were synthesized with different microstructures: linear epoxidized poly(ethylene glycol) (linear EPEG), 4-arm star-shaped epoxidized poly(ethylene glycol) (4A-EPEG), and 4-arm star-shaped poly(lactic acid-glycolic acid)-epoxidized polyethylene glycol (4A-PLGA-EPEG). These telechelic polymers that take the reactive epoxy groups on the terminals of the chains endowed the reactive compounding with the PLA matrix to achieve the mechanical enhancement of the blends. At a low loading level (3 wt%), the introduction of 4A-PLGA-EPEG significantly improved the toughness of the PLA-based blends with a substantial increase in elongation at break of 107.43% compared to only 3.84% for the neat PLA material. In contrast to linear EPEG and 4A-EPEG, the 4A-PLGA-EPEG copolymer served as a mechanical toughening agent because of its enhanced compatibility and the formation of topological entanglements with the polymeric matrix in the blends. The calculation of the efficiency factor ( η ) quantified the improvement in the microstructure stability and stress transfer efficiency of blends derived from the chain entanglements of the added copolymer, and molecular simulations further confirmed the formation of a micro-topological structure by reactive compounding in PLA-based blends.

Background Synthetic musk ketone (MK) is extensively used in perfumes, cosmetics, and detergents. Due to its high lipophilicity, persistence, and limited removal efficiency in wastewater treatment, MK has been detected in various environmental matrices and human tissues. However, the ecotoxicity of MK remains poorly characterized. This study aimed to systematically evaluate the toxicological effects of MK and elucidate its underlying mechanisms using Caenorhabditis elegans ( C. elegans ) as a model organism. Methods Wild-type C. elegans (strain N2) were exposed to MK at concentrations ranging from 0.4 to 20 mg/L for 24 h. Physiological endpoints including body size, locomotor activity, lifespan, and brood size were assessed. Biochemical markers comprising reactive oxygen species (ROS) levels and lipofuscin accumulation were quantified. Acute heat-stress tolerance was evaluated to assess stress resistance. Transcriptome sequencing (RNA-seq) and quantitative real-time PCR (qRT-PCR) were employed to investigate molecular mechanisms. Differential gene expression analysis was performed using DESeq2, and functional enrichment analyses were conducted for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Results MK exposure significantly and concentration-dependently reduced body length and width, locomotor activity (head thrash and body bend frequencies), brood size, and lifespan. Lipofuscin accumulation and intracellular ROS levels were markedly elevated. Acute heat-stress tolerance was significantly impaired. Transcriptomic analysis identified 159 differentially expressed genes (DEGs) at 2 mg/L MK (19 up-regulated, 140 down-regulated) and 136 DEGs at 20 mg/L MK (30 up-regulated, 106 down-regulated). Key DEGs included ugt-30 (detoxification), Y9C9A.16 (oxidation-reduction), msp-59 (spermatogenesis), and acdh-8 (lipid metabolism). GO enrichment revealed significant alterations in spermatogenesis, protein catabolism, and kinase activity. KEGG pathway analysis identified perturbations in sulfur metabolism, branched-chain amino acid metabolism, fatty acid metabolism, and apoptosis. Protein-protein interaction network analysis identified cyc-2.2 and acdh-8 as hub genes. Conclusions MK exposure induces multi-faceted toxicity in C. elegans , including developmental impairment, neurotoxicity, reproductive toxicity, accelerated aging, and diminished stress resilience. These adverse outcomes are strongly associated with oxidative stress, germline impairment, and disrupted lipid metabolism, suggesting that these pathways play central roles in MK-induced toxicity. Our findings indicate that environmental exposure to MK may pose significant toxicological risks to living organisms and warrant further assessment of its ecological and health impacts.

Wood, a sustainable building material, faces limitations due to its inherent low mechanical strength and flammability. This study develops a biodegradable, high-strength, and flame-retardant wood composite through a synergistic strategy combining sodium alginate-induced biomimetic mineralization of calcium carbonate with physical densification. The resulting material achieves a limiting oxygen index of 31.5%, meeting the standard for high-performance flame-retardant materials. Its specific modulus reaches 28.26 GPa·cm³·g⁻¹, surpassing that of aluminum. Notably, cone calorimetry analysis reveals a synergistic suppression of smoke production. Environmental evaluations confirm the composite retains excellent biodegradability and exhibits low ecotoxicity. Utilizing industry-compatible processes and low-cost raw materials, this approach offers a scalable and practical pathway for producing advanced bio-based construction materials.

FeSiAl-based soft magnetic composites (SMCs) for medium- and high-frequency electromagnetic devices require high permeability, low core loss, and efficient thermal management. However, current insulation coating strategies are limited by poor coating continuity, weak interfacial adhesion, and insufficient thermal stability. In this work, FeSiAl/Si 3 N 4 SMCs were fabricated via two-step plasma-assisted milling (PAM) combined with magnetic-field-assisted orientation forming, with the vibration frequency in the second PAM step used to regulate the microstructure, interfacial characteristics, and overall performance of the composite powders and compacts. The results show that Si 3 N 4 was successfully introduced onto the powder surface while preserving the crystal structure of the FeSiAl matrix, thereby establishing chemically bonded interfaces involving Si–N, Si–O–N, and M–N (M = Fe, Al). First-principles calculations confirm that the FeSiAl(110)/Si 3 N 4 (120) heterointerface exhibits a binding energy of −5.08 J/m 2 , with its stability originating from charge transfer and the formation of Fe–N, Al–N, and Si–N bonds. As vibration frequency increased, the continuity of the Si 3 N 4 coating layer and the interlayer insulating network first improved and then deteriorated. The 1300 rpm sample exhibited an effective permeability of 99.8 at 1 MHz, with a decline of less than 2% over 1 kHz–1 MHz, together with a saturation magnetization of 165.2 emu/g, an electrical resistivity of 192.1 Ω m, a total core loss of 72.8 kW m −3 at 50 mT/100 kHz, and a thermal conductivity of 28.3 W m −1 K −1 . These results indicate that regulating the PAM frequency provides an effective route for coordinating the magnetic, electrical, and thermal properties of FeSiAl-based SMCs.

Background Gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) are common metabolic complications during pregnancy. GDM is an independent risk factor for HDP, while HDP is a major contributor to maternal and perinatal morbidity and mortality. Reliable early tools for identifying women with GDM who are at risk of subsequently developing HDP remain limited. This study aimed to integrate metabolomic, lipidomic, and clinical data to identify reproducible candidate biomarkers associated with subsequently diagnosed HDP in women with GDM and to characterize the accompanying metabolic and lipidomic alterations. Methods In this prospective exploratory biomarker study, a discovery cohort (n = 128) and a validation cohort (n = 55) were recruited. Serum samples collected at 24–28 weeks of gestation were analyzed using untargeted and targeted metabolomics. Lipidomics was performed to complement the metabolomic analysis and characterize lipid-related alterations. A combined predictive model was constructed using logistic regression, and its predictive performance was evaluated using receiver operating characteristic (ROC) analysis. Results Untargeted metabolomics identified lower serum acetyl-L-carnitine (ALC) in the GDMHDP group than in the GDM group, and this difference was confirmed by targeted LC–MS/MS in the validation cohort. The combined ALC–diastolic blood pressure (DBP) model achieved an area under the curve (AUC) of 0.907 in the discovery cohort and 0.886 in the validation cohort. Adding ALC to DBP improved discrimination and reclassification in both cohorts. Multi-omics analysis showed complementary and partly distinct lipid associations with ALC and DBP. Lower ALC was associated with selected ceramide and monolysocardiolipin species, as well as with lipid patterns consistent with altered fatty-acid handling, whereas DBP showed a partly distinct pattern of lipid correlations. Conclusions Reduced serum ALC at 24–28 weeks of gestation was reproducibly associated with GDM complicated by HDP. Combining ALC with DBP improved discrimination between GDMHDP and uncomplicated GDM, suggesting complementary metabolic and hemodynamic information. Given the modest number of GDMHDP cases and the single-center design, these findings should be interpreted as exploratory and hypothesis-generating; they support further evaluation of ALC as a candidate metabolic marker but require confirmation in larger independent cohorts.

Ultrawide-bandgap (UWBG) perovskites are essential for monolithic all-perovskite triple-junction solar cells. However, their performance is limited by severe surface wrinkling, halide heterogeneity and large open-circuit voltage deficits originating from high Br–I ratios. Here we develop a surface reconstruction and halide homogenization strategy that simultaneously regulates crystallization and eliminates stress-induced morphological disorder in 2.0-eV bandgap perovskites. Through synergistic solvent and additive engineering, involving solvent-induced surface reconstruction and transient Cl − incorporation from oleylammonium chloride, surface wrinkling is suppressed, and Br/I crystallization is synchronized with promoted homogeneous halide distribution. The resulting UWBG perovskite films show uniform surface potential, suppressed non-radiative recombination, improved carrier mobility and an open-circuit voltage of 1.46 V. Integrating this UWBG subcell with optimized 1.6- and 1.22-eV absorbers yields monolithic all-perovskite triple-junction solar cells with 30.1% power conversion efficiency (certified 29.3%) and robust operational stability, providing a promising route towards >35% efficient all-perovskite multijunction photovoltaics.
