Electronic skin (E-skin) that emulates the human skin's three basic functions (perception, protection, and thermoregulation) has broad applied potential in smart healthcare and human-machine interaction (HMI). To fully realize the integration functions and simulate the structure of real skin, this work reactivates the “dead leather” back to intelligent E-skin (Leather/Ag/Polyborosiloxane elastomer) and further develops its application in harsh scenarios. The Ag nanowires/flakes incorporated leather fiber acts as the dermis layer to endow the E-skin with good electric conductivity, force sensitivity, and electrothermal management. The hierarchical structure allows the incident electromagnetic waves to be reflected and absorbed multiple times, possessing a superior electromagnetic interference (EMI) shielding value (≈75 dB). Due to the unique rate-dependent shear stiffening effects originated from the polyborosiloxane elastomer, the E-skin achieves significant force buffering capacity (≈47%) and excellent energy dissipation (over 85%). Moreover, the LAP E-skin exhibits unconventional sensing behavior, including piezoresistive sensing and impact stimulation, allowing for differentiation between low-energy and high-energy stimuli. On this basis, an elegant smart vest is successfully developed with exceptional thermal therapy, accurate contact perception, and wireless impact monitoring, demonstrating broad potential in the next generation of wearable protective equipment and smart robotics.

Conductive cardiac patches can rebuild the electroactive microenvironment for the infarcted myocardium but their repair effects benefit by carried seed cells or drugs. The key to success is the effective integration of electrical stimulation with the microenvironment created by conductive cardiac patches. Besides, due to the concerns in a high re-admission ratio of heart patients, a remote medicine device will underpin the successful repair. Herein, we report a miniature self-powered biomimetic trinity triboelectric nanogenerator with a unique double-spacer structure that unifies energy harvesting, therapeutics, and diagnosis in one cardiac patch. Trinity triboelectric nanogenerator conductive cardiac patches improve the electroactivity of the infarcted heart and can also wirelessly monitor electrocardiosignal to a mobile device for diagnosis. RNA sequencing analysis from rat hearts reveals that this trinity cardiac patches mainly regulates cardiac muscle contraction-, energy metabolism-, and vascular regulation-related mRNA expressions in vivo. The research is spawning a device that truly integrates an electrical stimulation of a functional heart patch and self-powered e-care remote diagnostic sensor.

Molybdenum disulfide (MoS2) has recently attracted considerable interests due to its unique properties and potential applications. Chemical vapor deposition (CVD) method is used widely to grow large-area and high-quality MoS2single crystals. Here, we report our investigation on thermal strain-fractured (SF) single crystalline MoS2, oxidation-fractured MoS2, and normal MoS2by atomic force microscopy (AFM), Raman and photoluminescence (PL) measurements. Several new Raman modes are observed for SF-MoS2. The band gap of SF-MoS2is enlarged by 150 meV and the PL intensity is reduced substantially. These results imply that a structural transformation occurs in SF-MoS2. Our findings here are useful for the design of MoS2-based nanocatalysts with relative high catalytic activity.Keywords:thermal strain-fractured MoS2;defect;Raman spectrum;photoluminescence spectrum;structural transformation

This study investigated the synergistic effect of fat and sarcoplasmic protein on the flavor profile of chicken white soup. The impact of adding 2% fat (2%O), 0.56% sarcoplasmic protein (0.56%P), and their combination (2%O-0.56%P) on volatile compounds, taste components, and sensory characteristics was evaluated. Through odor activity value (OAV) and gas chromatography-olfactometry (GC-O) analysis, hexanal, heptanal, octanal, nonanal, (E,E)-2,4-decadienal, (E)-2-octen-1-al, and 1-octen-3-ol were identified as key aroma contributors. The combination of 2%O and 0.56%P markedly enhanced the aroma profile of the chicken soup, concurrently achieving the highest levels of amino acids and 5′-nucleotides. Furthermore, electronic tongue analysis revealed that the chicken soup supplemented with 2%O-0.56%P exhibited the lowest bitterness value and achieved the highest overall acceptability. These findings demonstrate that the synergistic effect of fat and sarcoplasmic protein effectively improves the flavor quality of chicken white soup, providing a theoretical basis for developing flavorful, tasty, and consumer-preferred chicken soup products.

The fermentation rounds in the brewing process of Qingxiangxing Baijiu (QXB) significantly influence its quality and flavor. This study investigates the flavor characteristics of two rounds of QXB: Dacha-Baijiu and Ercha-Baijiu. Analysis via HS-SPME-GC × GC-TOFMS revealed a higher number of volatile organic compounds (VOCs) in Ercha-Baijiu, whereas Dacha-Baijiu exhibited elevated concentrations of alcohols and esters. Orthogonal partial least squares discrimination analyses indicated significant flavor differences between the two rounds. Based on odor activity value (OAV >1) assessment, 51 VOCs were identified as key aroma contributors, with β-damascenone, isovaleraldehyde, ethyl caprylate, and ethyl hexanoate being particularly prominent. Furthermore, 37 volatile compounds were accurately identified using GC-IMS, effectively constructing a fingerprint of the flavor differences between two rounds of QXB. Sensory analysis revealed significant distinctions in both aroma and taste. Dacha-Baijiu exhibited more intense aroma of sweet, floral, and grain, as well as taste of sour and fresh, while Ercha-Baijiu was marked by strong acid, alcoholic, and fruit aroma, as well as sweet, bitter and salty taste. This study elucidates the flavor characteristics of two rounds of QXB, which providing valuable insights for the processing technology and flavor quality control of QXB.

The cooking process exerts a notable influence on the flavor characteristics of fish. E-nose, GC-MS, and GC-IMS technologies were utilized to investigate how three thermal processing methods (steaming, frying, and roasting) alter the volatile odors of paddy field carp (PFC). GC-MS and GC-IMS analyses indicated that the volatile compound compositions of steaming and raw samples were relatively similar. Unique compounds such as hexanal, nonanal, and 2, 3-octanedione endowed paddy field carp with grassy, fatty, and fishy odors. Roasting significantly increased both the variety and content of volatile compounds. The content of pyrazines increased significantly after frying. E-tongue showed a substantial increase in umami taste after cooking, with roasting having the highest equivalent umami concentration at 29.95 mg/100 g. Sensory evaluations revealed that frying scored the highest overall (78.08) and was most favored. This study offered insights for further processing, flavor enhancement, and quality improvement of PFC.

BACKGROUND Insect odorant receptors (ORs) play a crucial role in the peripheral olfactory system in detecting odorants. The ORs of Lissorhoptrus oryzophilus (RWW), namely LoryOR7, LoryOR20 and LoryOR27, have been identified, yet only LoryOR20 has been functionally characterized and shown to respond to phenylacetaldehyde (PAA). Most LoryORs remain to be further explored. RESULTS Quantitative real-time (qRT)-PCR revealed significant expression of LoryOR24 in the antennae. We used the Xenopus laevis oocyte expression system and two-electrode voltage clamp (TEVC) technique to express LoryOR24/LoryOrco to detect the effects of rice volatiles, and two rice volatiles were found to be active. As the concentration of ( E , E )-2,4-heptadienal gradually increased, the EAG response amplitude of RWWs also increased, peaking at 100 μg μL −1 (8.09 ± 0.61 mV). The behavioral assay confirmed that RWWs exhibited a significant response to 10 μg μL −1 ( E , E )-2,4-heptadienal, with an attraction rate of 77.51%. After silencing LoryOR24 via RNAi, RWWs showed significantly reduced electrophysiological and behavioral responses. Furthermore, molecular docking and site-directed mutagenesis identified that residue F133 is critical for the ligand binding and functional activation of LoryOR24. CONCLUSION The results of our study reveal the molecular basis underlying RWW's recognition of ( E , E )-2,4-heptadienal, providing a foundation for the discovery of potential genetic targets at the peripheral olfactory perception level. © 2026 Society of Chemical Industry.

The research utilized a combination of gas chromatography–mass spectrometry (GC–MS), gas chromatography-ion mobility spectrometry (GC-IMS), and E -nose to examine the impact of fat addition on the aroma profile of chicken white soup. The concentration of volatile flavor compounds in the white soup significantly increased with rising fat addition. A total of 105 volatile compounds were detected in the soup through GC–MS, and 72 by GC-IMS. Moreover, adding 2 % fat could effectively enhance the aroma of the chicken soup, and the soup exhibited the highest concentration of free amino acids (211.29 μg/mL) and nucleotides (27.55 mg/100 mL). However, the taste activity value of 5′-nucleotides was below 1, suggesting that fat addition had minimal impact on the umami taste of white soup. The study demonstrates that appropriate fat supplementation can enhance the aroma of chicken white soup and lays a theoretical groundwork for the advancement of premium-quality chicken white soup with rich aroma.

Non-Hg catalyst is vital for the cleaner production of polyvinyl chloride (PVC), whereas the usual pure metal or pure metal salt precursor is too expensive for non-Hg catalysts preparation. Herein, a relatively cheap electronic waste (E-waste) leaching solution was employed as precursor to prepare acetylene hydrochlorination catalyst (EWC) for the first time. Resultantly, relatively better catalytic performance than that of pure metal salt-based catalysts was achieved on EWC. Additionally, Au, Ni, Sn, and S could play a positive role than other coexisting ions, whereas other elements would hardly have any impact at all. After Brunauer–Emmett–Teller (BET), x-ray photoelectron spectroscopy (XPS), x-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), and H 2 -temperature-programmed reduction (TPR) studies, it was proved that catalytic performance of EWC is mainly attributed to the efficient dispersion effect of other metals on active species like copper. Moreover, density functional theory (DFT) study further revealed that other metal components “solvent” role hindered the agglomeration of the active Cu component. This study offered a new route for decreasing the cost of vinyl chloride monomers (VCMs) in non-Hg preparation.

The rapid identification of chemical composition, temperature, and dynamic behavior of leaked liquids by robots during accidental spills of hazardous chemicals would significantly reduce the potential risks to both human health and the environment. Here, we designed a flexible, palm-shaped liquid-sensing e-skin (PSLSES) featuring 128 metal electrodes fabricated via flexible printed circuit (FPC) technology and coated with a fluorinated ethylene propylene (FEP) film. By capturing the local triboelectrification signals along the droplet's trajectory, PSLSES enables multimodal dynamic liquid sensing, simultaneously achieving liquid composition identification, temperature sensing, as well as droplet motion tracking through visualized trajectory patterns. Integrated with a one-dimensional convolutional neural network (1D CNN), PSLSES achieves an ultrahigh identification accuracy of 99.5% across 21 types of liquids, with a high monitoring resolution down to the ppb level and 98% accuracy in identifying liquid temperature. This includes deionized water, acids, bases, salts, and organic solutions, demonstrating broad liquid identification versatility. Compared with previously reported E-skin systems, it achieved faster identification (0.3 s), a lower detection limit (0.1 ppb), broader liquid recognition, and higher accuracy. The integration of PSLSES into wearable robotics systems opens new ways for robots to assist humans in analyzing and handling chemical leakage in hazardous environments.

Constructed an E. coli -ZnIn 2 S 4 biohybrid for photocatalytic H 2 production. • Achieved a high H 2 yield of 335 μmol under optimized conditions. • Demonstrated a synergistic effect surpassing individual component performance. • Revealed improved charge separation at the bio-abiotic interface. • Identified light-induced redirection of microbial metabolic flux. Semiconductor-microorganism hybrid systems exhibit considerable potential for light-driven hydrogen production via water splitting. However, their performance is limited by the efficiency of electron transfer at the bio-abiotic interface and the stability of the hybrid system. In this study, we constructed a novel light-driven hybrid hydrogen production system utilizing Escherichia coli ( E. coli ) and ZnIn 2 S 4 (ZIS). E. coli interacts with ZIS surface through specific interfacial interactions facilitated by electrostatic adsorption and forms robust connections via metal-nonmetal chemical bonds. The E. coli -ZIS hybrid demonstrated a significantly enhanced hydrogen evolution activity compared to pure ZIS or E. coli systems alone, achieving a hydrogen yield of 335 μmol within 3 h. Metabolic analysis revealed that ZIS can comprehensively regulate the microbial metabolic network to accelerate substrate decomposition and drive the reaction toward hydrogen production. By leveraging the light-enhanced synergistic mechanism of E. coli metabolic hydrogen production, the E. coli -ZIS composite system achieves efficient and stable photocatalytic hydrogen production.
