Superhydrophobic fabrics hold promise for soil salinization control, yet their practical application is hindered by insufficient durability under prolonged mechanical pressure and chemical exposure, coupled with reliance on fluorinated chemistries. Here, we report a robust, nonfluorinated superhydrophobic fabric engineered via a simple dip-coating process that integrates a polyolefin (POF) adhesive layer with alkylsiloxane-modified silica nanoparticles (HD-POS@SiO2) on a polyester substrate. The POF binder creates a unique “semiembedded” anchoring structure that locks nanoparticles onto fibers while preserving essential micro/nanoroughness, ensuring both strong adhesion and sustained superhydrophobicity. The resulting fabric exhibits exceptional durability: it retains superhydrophobicity (WSA < 7°) after 200 days under 33.3 kPa sand pressure and 64 days immersion in saline-alkali solutions. In simulated soil column tests, it suppresses topsoil salt accumulation by 84.8% (reducing surface salinity from 3.23% to 0.49%), while maintaining breathability and a favorable moisture-temperature balance. This work presents a scalable, eco-friendly strategy for fabricating pressure-resistant superhydrophobic textiles, offering a promising solution for sustainable agriculture and soil management.

To achieve high-performance microwave absorbers with broadband absorption, strong attenuation, thin thickness, and lightweight properties, current research focuses on optimizing impedance matching through microstructure design engineering and multicomponent integration. In this paper, porous carbon fibers loaded with heterotypic CoNi nanostructures are prepared via an integrated electro-blowing spinning, hydrothermal treatment, and calcination approach. The engineered heterotypic CoNi nanostructures act as compensators to optimize impedance matching while generating substantial interfacial polarization and promoting multiple electromagnetic wave reflection/scattering. The three-dimensional (3D) porous carbon fiber frameworks serve as a structural foundation, establishing conductive networks to enhance conduction loss, while providing growth sites for heterotypic CoNi nanostructures. Benefiting from microstructure design engineering and multicomponent integration, the composites achieve synergistic magnetic/dielectric losses, improved impedance matching, and enhanced electromagnetic wave attenuation. As a result, the optimized cactus-like CoNi/PCF-UN architecture assembling with surface nanoneedles and nanosheets exhibits exceptional absorption performance: a minimum reflection loss (RLmin) of −40.32 dB at 14.29 GHz and an effective absorption bandwidth (EAB) of 6.25 GHz at 2 mm thickness. This work provides valuable insights for developing high-performance microwave absorbers through multicomponent integration and microstructure design engineering.

Accurate monitoring of the mechanical activity of muscle tissue is crucial for myocardial function assessment, human–machine interaction, and flexible electronics, yet it remains challenging to achieve mechanically compliant sensing with stable mechanical coupling to soft biological tissues. Here, we report a mechanically tunable and photocurable conductive hydrogel based on polyacrylamide/polyethylene glycol diacrylate/lithium phenyl-2,4,6-trimethylbenzoylphosphinate/silver nanowire (PAAm/PEGDA/LAP/AgNWs) composites. By rationally modulating the double-network structure and the AgNWs content, the material achieves a balanced integration of a Young’s modulus (162 ± 9 kPa) matching that of muscle tissue, ultrahigh stretchability (>1200%), and stable electrical sensing, enabling effective force sensing under physiological deformation. Moreover, the photocurable nature of the hydrogel allows high-resolution fabrication via digital light processing (DLP) 3D printing, enabling in situ monolithic integration of sensing and encapsulation layers, which overcomes the manufacturability limitations of many previously reported conductive hydrogels. Two proof-of-concept devices were developed to demonstrate cross-type muscle sensing and cross-scale force detection, including long-term monitoring of contractile forces (15–30 μN) from in vitro cultured myocardial tissues using a microcantilever structure, and wearable facial muscle tension sensing in the range of 1–5 mN. This work demonstrates a scalable conductive hydrogel sensing platform that combines tissue-matched mechanics, advanced manufacturability, and broad biomechanical sensing capability, highlighting its potential for biomechanical research and human–machine interaction applications.

To meet the requirements for remote optical thermometry, Er3+- and Ho3+-doped Cs2NaYbCl6 double perovskites with intense upconversion (UC) emissions were designed. Excited by 980 nm, characteristic emissions of Er3+ and Ho3+ were detected, with optimal doping concentrations of 30 and 50 mol % in the Cs2NaYbCl6 host, respectively. The near-infrared light-triggered UC luminescence mechanism was investigated through the pump power-dependent UC emission spectra. Moreover, using the fluorescence intensity ratio (FIR) technique, temperature sensing performance was explored by analyzing the UC emission evolution from thermally coupled levels (TCLs) and non-TCLs of rare-earth ions. Based on the TCLs of Er3+, the maximum relative sensitivity (Sr) of the resulting compound reached 1.15% K–1, while it declined to 0.43% K–1 when the non-TCLs of Er3+ were employed, featuring an ultrabroad operating range of 303–813 K, demonstrating that the selection of a proper sensing strategy is an efficient route to regulate the thermometric properties of the studied samples. Furthermore, when the non-TCLs of Ho3+ were used, the target material exhibited a maximum Sr value of 1.12% K–1, which is dependent on the sensing mode, and its working temperature range was 303–543 K. The distinct Sr values confirmed that doping engineering effectively tailors the thermometric behavior. This work demonstrates that rare-earth-ion-doped Cs2NaYbCl6 double perovskites are promising for optical thermometry, with tunable thermometric capabilities via the dual engineering of doping and sensing strategies.

Developing redispersible nanocellulose products is crucial for their industrial applications. However, challenges persist in developing convenient and efficient processes. This study presents a green strategy using dynamic covalent chemistry to tune the hydrogen-bonding network of cellulose nanocrystals (CNCs). CNCs were combined with sodium lipoate (SL) in an aqueous solution and dried to form composite films. SL incorporation effectively prevents CNC aggregation via electrostatic repulsion and steric hindrance, transforming the CNC skeleton structure from a “bundle-to-bundle” structure to a uniform, horizontally stacked architecture. The composite films exhibited enhanced transparency, surface smoothness, and tunable mechanical properties. Upon water immersion, SL depolymerized and separated with 100% recovery. The remaining CNC skeleton readily redispersed into individual nanocrystals via sonication, achieving near-complete recovery even with 15% SL. This simple, water-based process tailors CNC film performance and enables complete closed-loop recycling, offering sustainability and simplicity for advanced applications.

The growth in oil demand has driven technological innovation in enhanced oil recovery (EOR). Chemical flooding, widely adopted for its effectiveness in improving oil recovery, enhances the macroscopic sweep efficiency by altering interfacial properties. However, strong oil–solid adhesion leads to residual oil, posing a key technical challenge. Although low-salinity water flooding can disrupt the hydrated ion bridge structure, its efficacy is limited, and it fails to fully resolve residual oil issues. To tackle this residual oil challenge, we developed traditional Chinese medicine (TCM) composite agents based on polyphenol–silicon complexation with dual EOR functions: in situ oil displacement and long-term oil isolation. Under weak alkaline conditions, the TCM composite agent continuously reacts with silicon, overcoming van der Waals forces between crude oil and silicate, thereby effectively displacing oil in micron-scale grooves. The polyphenol–silicon complexes, along with polyphenol, form a hydrophilic coating with micro/nanostructures via π–π interactions, maintaining superoleophobic and nonadhesive properties against crude oil even after 1 week. Additionally, the TCM agents altered the wettability of shale from oil-wet to water-wet and achieved an 88.24% recovery rate in core flooding tests. This breakthrough offers a solution for crude oil recovery, promoting efficient and environmentally sustainable development in the industry.

Achieving a harmonious balance among healability, high mechanical strength, and exceptional toughness remains a persistent and formidable challenge in the development of artificial ligaments. Herein, we report a class of polyphenol-based reversible cross-linked polyurethanes (RCPUs) designed to overcome this long-standing performance trilemma. By synergistically integrating dynamic hydrogen bonds, phenolic urethane bonds, and finely engineered microphase separation structures, the RCPUs achieve an exceptional combination of mechanical robustness, self-healing capability, and antibacterial activity. The optimized RCPU1.8 demonstrates a tensile strength of ∼57.5 MPa and toughness of ∼323.8 MJ m–3, along with a healing efficiency of ∼88.1% after 12 h at 75 °C. Furthermore, a simple prestretching treatment significantly enhances the tensile strength to ∼167.7 MPa while maintaining excellent fatigue resistance over 100 loading cycles. This work provides a scalable and synergistic strategy for developing next-generation multifunctional artificial ligaments with well-balanced performance.

Symmetrically branched metal nanostructures with intricate structural features and exceptional physicochemical properties demonstrate a significant potential for diverse applications. Nevertheless, achieving precise morphological control over these nanostructures with adjustable dimensions poses a considerable challenge, especially for stellated icosahedrons (STICs) with 20 orderly arranged branches. Here, we present a template replication strategy for the controllable synthesis of metal STICs with various compositions, featuring high yield, uniformity, and adjustable dimensions. The synthesis relies on fine-tuning the reduction kinetics toward heterogeneous nucleation and growth through optimizing the reduction potential of the metal precursors. Notably, the synthesized Au STICs exhibit tunable localized surface plasmon resonances and scattering spectra by varying their sizes as well as profound surface-enhanced Raman scattering (SERS) activity. Electron energy-loss spectroscopy and numerical simulations confirm the symmetrical distribution of their surface plasmon resonances, enabling the polarization-angle-dependent SERS enhancement. Moreover, the resulting magnetic Ni-NiPx STICs exhibit chain-like self-assembly under magnetic fields. This work offers an approach to the rational synthesis of branched nanostructures with complex and intricate architectures that hold significant promise for applications in SERS and catalysis.

Lethal amatoxins (AMAs) and toxic phallotoxins (PHLs) are the primary causes of mushroom poisoning, necessitating rapid detection methods. Utilizing similarity and quantum chemical analyses for hapten screening, this study successfully developed monoclonal antibody (mAb) 3A9 with high and uniform sensitivity to phalloidin and phallacidin (IC50: 1.32 and 1.52 ng/mL). Furthermore, the heterologous hapten α-AMA-HS greatly improved the uniform recognition of mAb 3G9 to α-, β-, and γ-AMA (IC50: 0.46, 0.67, and 0.51 ng/mL). Using these mAbs, a dual-target fluorescent immunochromatographic assay (DT-FICA) was developed to detect PHLs and AMAs simultaneously in mushrooms. It showed calculated limits of detection of 3.28 and 1.24 μg/kg in dry weight and 1.08 and 1.00 μg/kg in fresh weight. DT-FICA has demonstrated its accuracy and reliability through spiked recovery tests and real-sample analysis, providing a sensitive, specific, simple, and cost-effective tool for preventing mushroom poisoning and safeguarding public health.

Red phosphorus (P), with high theoretical specific capacity and environmental benignity, represents a promising anode material for lithium-ion batteries (LIBs). However, its practical application is hindered by intrinsic limitations, such as poor electronic conductivity and substantial volume fluctuation, resulting in sluggish redox reaction kinetics and compromised reaction reversibility. Herein, we design a 3D P-bonded radially-oriented Ti 3 C 2 microsphere composite electrode (P80/MS-Ti 3 C 2 ) via an innovative electrostatic spraying technique. The unique, highly conductive, radially-oriented Ti 3 C 2 matrix uniformly and tightly encapsulates P nanoparticles within the channels, which establish continuous ion/electron pathways and prevent the aggregation of 2D Ti 3 C 2 sheets. Simultaneously, the formation of robust Ti-O-P covalent bonds at the interface significantly enhances the intrinsic electronic conductivity and alleviates the volume expansion and exfoliation of red P during cycling. The synergistic integration of stabilized covalent interfaces and meticulously-engineered architecture endow the optimized P80/MS-Ti 3 C 2 electrode with high reversible specific capacities and outstanding cycling stability, achieving 1269.5 mAh g − 1 at 500 mA g − 1 after 700 cycles and 1064.3 mAh g − 1 at 1 A g − 1 after 1000 cycles even under a high P loading of 36.7%, with P approaching its theoretical capacity. This work provides an effective structural and interfacial engineering strategy to overcome the fundamental challenges of P-based electrodes, demonstrating great potential for high-performance LIBs.

A flexible polyionic liquid (PIL) nanofiber membrane-supported phosphomolybdic acid catalyst (PM-PIL) was fabricated via stepwise chemical transformation of polyacrylonitrile (PAN) nanofiber membranes. The nitrile groups of PAN were converted into pyridine units, followed by quaternization and anion exchange with phosphomolybdic acid (PMo), resulting in a polyionic liquid membrane with uniformly immobilized PMo species. Benefiting from its nanofibrous architecture and ionic liquid characteristics, the PM-PIL membrane simultaneously acts as a heterogeneous catalyst and a Pickering emulsion stabilizer, enabling efficient interfacial catalytic oxidation desulfurization. The PM-PIL membrane exhibited excellent catalytic performance toward dibenzothiophene (DBT) oxidation in an H2O2-based model oil system. Under optimized conditions (60 °C, O/S = 150:1), more than 90% DBT removal was achieved within 90 min, and complete desulfurization was obtained within 2 h. Compared with phosphomolybdic acid and poly(pyridine), the PM-PIL membrane showed markedly enhanced activity and stability, maintaining over 90% efficiency after six cycles. Product analysis confirmed selective oxidation of DBT to dibenzothiophene sulfone. This work provides a robust and recyclable membrane-based catalytic platform for efficient oxidative desulfurization.

The storage quality of fresh-cut peach fruit is compromised by weight loss and chromatic aberration. In this experiment, taurine at 30 mg L−1was applied to fresh-cut peaches to evaluate its effect on storage quality. Changes in weight loss, chromatic aberration, antioxidant system, endogenous nitric oxide (NO) metabolism, endogenous hydrogen sulfide (H2S) metabolism, and phenylpropanoid metabolism were studied. The results indicated that 30 mg L−1taurine effectively improved the ability to scavenge ROS, including •OH, O2•−, MDA, and H2O2, by inhibiting the decrease in the activities of SOD and CAT, enhancing POD activity, reducing PPO activity, and maintaining the AsA-GSH cycle. Moreover, taurine treatment increased the activities of 4CL and PAL and retarded the decrease in the activities of SKDH and C4H, thereby improving the accumulation of total phenols, flavonoids, and lignin. These findings showed that taurine mitigated oxidative damage in fresh-cut peaches by enhancing the antioxidant defense system. Exogenous taurine consistently enhanced NOS-like activity while decreasing NR activity in the early storage phase, and elevated the contents of L-Arginine, nitrite, and endogenous NO. Taurine treatment up-regulated the activities of SAT, L-CD, and OAS-TL, thus promoting endogenous H2S content in fresh-cut peaches. Taurine alleviated weight loss and chromatic aberration in fresh-cut peaches during storage by enhancing the antioxidant system and modulating NO, H2S and phenylpropanoid metabolism.
