Electronic skin (e-skin) that adapts to dynamic environments requires simultaneous regulation of moisture and heat transport while maintaining reliable sensing capability. Here, a temperature-responsive electrode based on a polypyrrole@poly(N-isopropylacrylamide)@cellulose acetate)/poly[ N,N -dimethyl (methacryloylethyl) ammonium propane sulfonate]@cellulose membrane (PPy@PCA/PCM) bilayer is reported, which exhibits complementary wettability switching and reversible unidirectional water transport. At low temperatures, the electrode preserves moisture and heat, maintaining skin hydration level and temperature ≈4 and ≈5 °C higher than bare skin, respectively. At elevated temperatures, the wettability gradient reverses, promoting sweat evaporation and heat dissipation, with hydration level and temperature ≈6 and 4.2 °C lower than bare skin, respectively. Integrated into e-skin, the electrode enables real-time hydration and temperature sensing while dynamically regulating moisture and thermal flux when the environment changes, avoiding skin erythema after long-term wear. Moreover, the PPy@PCA/PCM electrode shows excellent mechanical durability, chemical stability, and cytocompatibility. This adaptive electrode design offers a versatile strategy for multifunctional e-skin that simultaneously ensures physiological signal fidelity and enhances user comfort under varying conditions.

The Electro-Fenton (E-Fenton) technique has shown great potential in wastewater treatment, while the sustainable and continuing supply of Fe2+remains challenging. Herein, we demonstrate the construction of a novel E-Fenton system by magnetically decorating zero-valent iron (ZVI) onto a RuO2-IrO2/Ti (ZVI-RuO2-IrO2/Ti) electrode for high-efficient treatment of pharmaceutical wastewater, which is considerably refractory and harmful to conventional biological processes. By using ZVI as a durable source of Fe(II) irons, 78.69% of COD and 76.40% of TOC may be rapidly removed by the developed ZVI-RuO2-IrO2/Ti electrode, while the ZVI-RuO2-IrO2/Ti electrode using ZVI only reduces 35.64% of COD under optimized conditions at initial COD and TOC values of 5500 mg/L and 4300 mg/L, respectively. Moreover, the increase in BOD5/COD from 0.21 to 0.52 highlights the enhanced biodegradability of the treated effluent. The analysis of a simultaneously formed precipitation on electrodes suggests that the coagulation process dominated by Fe3+/Fe2+also plays a non-negligible role in pharmaceutical wastewater treatment. In addition, the monitoring of the evolution of nitrogen elements and the formation of by-products in the E-Fenton process verifies its great capacity toward those organic pollutants found in pharmaceutical wastewater. Our study offers a practical solution for enhancing the performance of E-Fenton systems, and effectively treating refractory pharmaceutical wastewater.Keywords:electro-oxidation;zero-valent iron;pharmaceutical wastewater;E-Fenton process

The E-Commerce Law of the People's Republic of China(E-commerce Law) was enacted on August 31, 2018. One of the hottest topics is e-commerce platform operators (EPOs) liability for third-party patent infringement. The EPOs, which provide platform services rather than participating in trade directly, must try to maintain the balance between patentees and social interests. Due to the particularities of the patent infringement review, it is difficult for the EPOs to fulfil the task. Thus, the EPOs liability for copyright and trademark infringement is likely unworkable in the patent area. A China practice review will be helpful in analysing the problem; the guiding case No. 83 is an especially meaningful reference. The E-Commerce Law is principled and advisory - it is impossible to distinguish the limits of EPOs liability for third-party patent infringement by differentiating the patent from other intellectual property rights . After reviewing the regulations on the general and intellectual property duty of care of EPOs, this article argues that the E-Commerce Law still has some specific problems. Consequently, to implement the E-Commerce Law, judicial interpretation and detailed rules for implementation should be formulated as soon as possible, and the potential solutions are described in the conclusion.

Van der Waals forces and hydrogen bonding dominate the interactions between PLvPs and aldehyde. • PLvP conformational changes facilitate ALDH degradation of aldehyde. • ALDH restored PLvP structure and function post-aldehyde binding. • MD simulations confirmed E , E -2,4-heptadienal-induced conformational shifts. Yeast fermentation has been shown to reduce the concentration of aldehydes, characteristic off-flavors in animal livers, although the underlying mechanisms of deodorization remain unclear. This study investigated the oxidative catalytic degradation of E , E -2,4-heptadienal by ALDH (Aldehyde dehydrogenase) from Saccharomyces cerevisiae within a complex system of pig liver proteins (PLvPs) and the aldehyde compound. Fluorescence quenching, thermodynamic, and FTIR analyses demonstrated that E , E -2,4-heptadienal spontaneously bound to PLvPs primarily via van der Waals forces and hydrogen bonding. This binding induced conformational changes in PLvPs, which were found to enhance the susceptibility of E , E -2,4-heptadienal to ALDH-mediated degradation. Subsequent ALDH treatment significantly improved the binding capacity of the complexes (by 13.21–78.18%) and largely restored the functional and structural integrity of PLvPs. Molecular dynamics and docking simulations further supported that E , E -2,4-heptadienal binding to PLvPs facilitates ALDH catalysis via these conformational alterations. This study highlights the crucial role of ALDH-mediated oxidative catalytic degradation in modulating the flavor-binding capacity of PLvPs, offering a novel enzymatic strategy for targeted off-flavor elimination and enhancing the sensory quality and industrial utility of liver-based products.

(E)-2-hexenyl acetate (E2HA) is the esterification product of (E)-2-hexenal (E2H), which is generated by lipoxygenase (LOX) during the degradation of polyunsaturated fatty acids. As a green leaf volatile, E2HA is released in large quantities during the ripening or stress of fruits, forming a unique aroma of fruits and helping to resist stress, however, its the effect on fruit quality is still unclear. In this study, E2HA significantly affected the colour change process in tomato by activating carotenoid synthesis pathways (PDS, ZDS, LCY-β), resulting in increased lycopene and β-carotene contents while maintaining chlorophyll levels. E2HA upregulated LOX expression and activity, thereby promoting polyunsaturated fatty acid degradation. As a downstream product of E2H, E2HA reduces hydroperoxide lyase (HPL) gene expression and enzyme activity, thereby decreasing the endogenous E2H content. Concurrently, E2HA activated the jasmonic acid (JA) synthesis pathway (AOS, AOC, OPR3, COI-1, MYC2), leading to elevated endogenous JA levels. By redirecting LOX pathway flux toward JA biosynthesis, E2HA increased carotenoid accumulation. These findings suggest that E2HA is a natural compound for improving fruit quality, with promising applications in preharvest horticulture.

Carbapenem-resistant Enterobacterales (CRE) is an emerging global concern. Specifically, carbapenemase-producing (CP) E. coli strains in CRE have recently been found in clinical, environmental, and food samples worldwide, causing many hospitalizations and deaths. Their rapid identification and characterization are paramount in control, management options, and treatment choices. Thus, this study aimed to characterize the cell surface properties of carbapenem-resistant (R) E. coli isolates and their interaction with glycan-coated magnetic nanoparticles (gMNPs) compared with carbapenem-susceptible (S) E coli . This study used two groups of bacteria: The first group included E. coli (R) isolates harboring carbapenemases and had no antibiotic exposure. Their initial gMNP–cell binding capacity, with cell surface characteristics, was assessed. In the second group, one of the E. coli (R) isolates and E. coli (S) had long-term serial antibiotic exposure, which we used to observe their cell surface characteristics and gMNP interactions. Initially, cell surface characteristics (cell morphology and cell surface charge) of the E. coli isolates were evaluated using confocal laser scanning microscope (LSCM) and a Zetasizer, respectively. The interaction of gMNPs with the E. coli isolates was assessed through LSCM and transmission electron microscope (TEM). Further, the gMNP–cell attachment was quantified as a concentration factor (CF) through the standard plating method. The results showed that the CF values of all E. coli (R) were significantly different from those of E. coli (S), which could be due to the differences in cell characteristics. The E. coli (R) isolates displayed heterogeneous cell shapes (rod and round cells) and lower negative zeta potential (cell surface charge) values compared to E. coli (S). Further, this research identified the differences in the cell surface characteristics of E. coli (S) under carbapenem exposure, compared to unexposed E. coli (S) that impact their attachment capacity. The gMNPs captured more E. coli (S) cells compared to carbapenem-exposed E. coli (S) and all E. coli (R) isolates. This study clearly found that differences in cell surface characteristics impact their interaction with magnetic nanoparticles. The gained insights aid in further understanding adhesion mechanisms to develop or improve bacterial isolation techniques and diagnostic and treatment methods for CRE.

Rosa rugosa Thunb. can be skillfully blended with high-quality, mellow Baijiu to produce Rose Lujiu (RL), which emits a delightful aroma. In this study, e-nose, e-tongue, GC-MS, and GC-IMS were employed to analyze the aromatic compounds. Relative odor activity value (ROAV) analysis and orthogonal partial least squares discriminant analysis (OPLS-DA) were employed to comprehensively assess volatile compounds and predict key aroma compounds. A total of 111 volatile compounds were identified using GC-MS analysis. Additionally, GC-IMS analysis identified a total of 70 aroma compounds, among which 13 key contributors to the aroma were determined based on odor activity thresholds. These results indicate that ethyl acetate, ethyl butanoate, propyl hexanoate, and 3-methyl-1-butanol emerged as pivotal odorants enabling discrimination among different RL samples. These findings would provide valuable data for the application of commercial samples in the flavor modulation of RL.

E-tongue analysis shows that Isoleucine (Ile) enhances the overall flavor of flesh. • Ile affects volatile content in flesh, as shown by E-nose and GC–MS analysis. • Ile enhanced fatty acid (FA) synthesis and elevated FA content. • Ile promoted the movement of FA from lipid droplets to mitochondria for oxidation. • Ile increased adenosine phosphate content while decreasing hypoxanthine in flesh. This experiment used combination of electronic tongue, electronic nose, and gas chromatography mass spectrometry methods to analyze the impact of dietary isoleucine (Ile) on the flavor in grass carp muscle. Key findings include: Ile improved the sweetness and umami and reduced sourness and bitterness of the flesh. Ile inhibited sulfide and the relative content of volatile compounds like nonanal and hexanal in muscle. Second, Ile enhanced the content of adenosine triphosphate, adenosine diphosphate, and adenosine monophosphate, and decreased the content of hypoxanthine. Furthermore, Ile raised the content of fatty acid (FA) and the enzymes related to FA synthesis. Based on the above results, it can be concluded that dietary Ile improved flesh flavor by reducing the relative content of volatile compounds like 1-octen-3-ol and increasing the content of FA and nucleotides, providing valuable insights into improving flesh quality.

The absorption refrigeration system (ARS) was important for energy saving, which can be driven by low-grade energy. In this work, the mixtures of trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) + N-methyl-2-pyrrolidone (NMP) and R1234ze(E) + triethylene glycol dimethyl ether (DMETrEG) were considered as the promising new working fluids for ARS. The vapor–liquid equilibrium (VLE) data of R1234ze(E) + DMETrEG and R1234ze(E) + NMP binary mixtures were measured using a liquid-recirculation apparatus from 293.15 to 353.15 K. The VLE data were correlated by the five-parameter non-random two-liquid activity coefficient model, and the correlated results showed a good agreement with the experimental VLE data. The average absolute relative deviation and maximum absolute relative deviation of the pressure were 1.70 and 5.11% for R1234ze(E) + NMP and 1.30 and 3.22% for R1234ze(E) + DMETrEG, respectively. The two binary mixtures exhibited positive deviations from Raoult’s law.

It is a key focus in research on the interaction between different types of lipid and proteins for the aroma formation of fish. The interaction oxidation model of myofibrillar proteins and polar and non-polar lipid in different ratios was constructed to investigate the molecular mechanism of aroma formation of the large yellow croaker. The thermal interaction of lipid and protein was found to generate much more fishy compounds when the ratio of non-polar and polar lipid was 4:1. The aroma intensity reached the highest after thermal interaction at the ratio of non-polar and polar lipid was 1:1. As the proportion of non-polar lipid increased, the concentration of (E,E)-2,4-Heptadienal increased and reached 0.09 μg/g. Triglyceride was the main non-polar lipid that participated in thermal interaction with myofibrillar proteins for the formation of characteristic odorants of fish. As the amount of non-polar lipid increased, lipid oxidation and chain breakage made it easier to convert into volatile flavor compounds under the interaction of myofibrillar proteins. Further, this study provides certain support and influence for the regulation of flavor in fish processing by lipid.

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

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.
