The cotton cellulose nanofibers(CCNFs)/ZnO/CuS nanocomposites have been successfully fabricated by the electrospun-hydrothermal method and successive ionic layer adsorption. The results of XRD, SEM and TEM indicate that the CuS are successfully combined with the ZnO. The photocatalytic activity of the CCNFs/ZnO/CuS nanocomposites is investigated by the degradation of methylene blue under visible light irradiation, and it is demonstrated to be significantly enhanced after the CuS is introduced. Furthermore, the direct interfacial charge transfer of the ZnO/CuS is considered as the main reason for the enhancement.

Transition metal phosphides (TMPs) have exhibited decent performance in an oxygen evolution reaction (OER), which is a kinetic bottleneck in many energy storages and conversion systems. Most reported catalysts are composed of three or fewer metallic components. The inherent complexity of multicomponent TMPs with more than four metallic components hinders their investigation in rationally designing the structure and, more importantly, comprehending the component-activity correlation. Through hydrothermal growth and subsequent phosphorization, we reported a facile strategy for combining TMPs with tunable elemental compositions (Ni, Fe, Mn, Co, Cu) on a two-dimensional titanium carbide (MXene) flake. The obtained TMPs/MXene hybrid nanostructures demonstrate homogeneously distributed elements. They exhibit high electrical conductivity and strong interfacial interaction, resulting in an accelerated reaction kinetics and long-term stability. The results of different component catalysts’ OER performance show that NiFeMnCoP/MXene is the most active catalyst, with a low overpotential of 240 mV at 10 mA·cm −2 , a small Tafel slope of 41.43 mV·dec −1 , and a robust long-term electrochemical stability. According to the electrocatalytic mechanism investigation, the enhanced NiFeMnCoP/MXene OER performance is due to the strong synergistic effect of the multi-elemental composition. Our work, therefore, provides a scalable synthesis route for multi-elemental TMPs and a valuable guideline for efficient MXene-supported catalysts design.

Metal-free antiferroelectric materials are holding a promise for energy storage application, owing to their unique merits of wearability, environmental friendliness, and structure tunability. Despite receiving great interests, metal-free antiferroelectrics are quite limited and it is a challenge to acquire new soft antiferroelectric candidates. Here, we have successfully exploited binary CMBr x I 1- x and CMBr x Cl 1- x solid solution as single crystals (0 ≤ x ≤ 1, where CM is cyclohexylmethylammonium). A molecule-level modification can effectively enhance Curie temperature. Emphatically, the binary CM-chloride salt shows the highest antiferroelectric-to-paraelectric Curie temperature of ~453 K among the known molecular antiferroelectrics. Its characteristic double electrical hysteresis loops provide a large electric polarization up to ~11.4 μC/cm 2 , which endows notable energy storage behaviors. To our best knowledge, this work provides an effective solid-solution methodology to the targeted design of new metal-free antiferroelectric candidates toward biocompatible energy storage devices.

Background Nano-drug delivery systems show considerable promise for effective cancer therapy. Polymeric micelles have attracted extensive attention as practical nanocarriers for target drug delivery and controlled drug delivery system, however, the distribution of micelles and the release of the drug are difficult to trace in cancer cells. Therefore, the construction of a redox-sensitive multifunctional drug delivery system for intelligent release of anticancer drugs and simultaneous diagnostic imaging and therapy remains an attractive research subject.Results To construct a smart drug delivery system for simultaneous imaging and cancer chemotherapy, mPEG-ss-Tripp was prepared and self-assembled into redox-sensitive polymeric micelles with a diameter of 105 nm that were easily detected within cells using confocal laser scanning microscopy based on aggregation-induced emission. Doxorubicin-loaded micelles rapidly released the drug intracellularly when GSH reduced the disulfide bond. The drug-loaded micelles inhibited tumor xenografts in mice, while this efficacy was lower without the GSH-responsive disulfide bridge. These results establish an innovative multi-functional polymeric micelle for intracellular imaging and redox-triggered drug deliver to cancer cells.Conclusion sA novel redox-sensitive drug delivery system with AIE property was constructed for simultaneous cellular imaging and intelligent drug delivery and release. This smart drug delivery system opens up new possibilities for multifunctional drug delivery systems.

This research is centered on the design and synthesis of a highly efficient heterogeneous catalyst, 1%Ru-MgO- 400 °C, for the hydrogenation of pyrrole to pyrrolidine. As a key intermediate in pharmaceutical manufacturing and fine chemical production, pyrrolidine synthesis poses significant challenges in terms of efficiency. In this work, MgO was synthesized via the calcination of Mg(OH) 2 , followed by the deposition of Ru onto MgO- 400 °C through a sodium borohydride reduction approach to produce the 1%Ru-MgO- 400 °C catalyst. The catalyst demonstrated exceptional performance under conditions of 170 °C and 3.5 MPa H 2 pressure, achieving complete conversion of pyrrole and a 100% yield of pyrrolidine. Advanced characterization methods such as XRD, TG, BET, SEM and HR-TEM were used to analyze the catalyst, revealing that the ruthenium nanoparticles were uniformly loaded on the MgO carrier to form a highly dispersed active site, while the crystal structure of MgO remained intact with excellent thermal stability, providing a structural basis for the efficient performance of the catalyst. Additionally, the catalyst exhibited remarkable stability and retained high activity over multiple reaction cycles, highlighting its suitability for industrial-scale applications. The findings of this study contribute novel perspectives to the development of robust and efficient hydrogenation catalysts and present a sustainable approach for the environmentally friendly synthesis of pyrrolidine.

A novel Cu/Ti 3 C 2 T X laminated composite foil was prepared using a combination of electroplating and electrophoretic deposition. The results indicate that the average thermal expansion coefficient of the Cu/ Ti 3 C 2 T X composite foil decreased by 11.26% compared to that of pure copper. Due to the high electron mobility of Ti 3 C 2 T X and the favorable Cu/ Ti 3 C 2 T X interface, the electrical conductivity of the Cu/ Ti 3 C 2 T X composite foil exceeded that of pure copper by 8.7%, reaching 6.2147 × 10 7 S·m −1 , and its thermal conductivity increased from 381.5 W/m·K to 423.5 W/m·K. The study revealed that a thinner, looser Ti 3 C 2 T X layer with fewer layers is more favorable for copper penetration and filling, enabling a continuous network-like structure and resulting in significantly improved thermal and electrical properties of the composite copper foil. These findings position the Cu/Ti 3 C 2 T X foil as a promising candidate for electronic encapsulation and super-conductivity. Graphical Abstract

Time and temperature are the crucial factors affecting the quality of perishable products. The device capable of recording temperature fluctuation and maintaining time has huge practical potential. In this research, a novel thermal history indicator (THI) was proposed based on covalent organic frameworks (COFs) with the irreversible color change performance. The color change and absorbance of the THI were investigated over a broad monitoring temperature range (− 22 ~ 55 ℃) and were closely correlated with its thermal accumulation over time and temperature. The activation energy ( E a ) of the THI was calculated to be 55.31 kJ mol −1 , which can be used to monitor the perishable products with deterioration reaction E a ranging from 30.31 to 80.31 kJ mol −1 . In addition, the THI also demonstrated the significant response to the environmental temperature fluctuations. Furthermore, the potential applications were evaluated by recording the changes of the THI gel and the total viable count (TVC) of food under the same conditions. The results indicated that the digital images of the colorimetric THI gel were correlated with TVC of food at 4 ℃ and 25 ℃, respectively. These results support that the proposed THI is potential for real-time, accurate, non-destructive, visually, and quantitatively monitoring food freshness during food supply chain distribution.

Herein, we report a cooling fabric with thermal conduction and radiative cooling capabilities through grafting hydroxylated boron nitride (BN-OH) nanosheets onto the surface of cotton fibers. The thermal conduction layer formed by BN-OH nanosheets enables the modified fabric with excellent thermal conductivity, which is 42% higher than that of the original cotton fabric. Resulting in the modified fabric exhibits great cooling power and increases the cooling setpoint temperature by 1 °C, which corresponds to reduced 11.2% indoor cooling energy consumption. Additionally, the Mid-infrared emissivity and solar reflectivity are increased to 90% and 70.4%, respectively, suggesting that wearing modified fabric under direct sunlight can enable the artificial skin to avoid overheating by 7.8 °C compared to bare skin. Moreover, the modified fabric also presents a considerable contact cool feeling, impressive wearability, and durability. We expect this work to present new insights for the design of personal thermal management textiles. Graphical abstract

Malignant pleural effusion (MPE), persistently generated by thorax tumor cells at the advanced stage, remains a major challenge for cancer therapy. Herein, we develop an ultra-sensitive piezoelectric nano-system by doping ytterbium in metal-organic framework (O 3 P@LPYU), which can be triggered by physiological intrapleural pressure during breath. Under the gently alterative pressure, the piezoelectric nanoparticles with notable peroxidase-like activity effectively produce a burst of reactive oxygen species and induce immunogenic cell death by catalysis of carried ozone as well as peroxide in interstitial fluid. A clear and sustained biodistribution is observed in thorax effusion and tumors upon intrapleural administration of particle. Remarkably, due to the abundant substrates in oxygen-rich environment of pleural cavity, O 3 P@LPYU particle provides a potent reduction of MPE volume and durable inhibition of tumor growth in thorax. Our work not only develops a bio-responsive piezoelectric nano-system, but also provides a strategy for persistent suppression of MPE in clinics.

Fe–N–C single-atom catalysts are considered among the most promising non-precious metal-based catalysts for oxygen reduction reaction (ORR), but issues such as low utilization of active sites and the easy aggregation of single atoms severely hinder their application in fuel cells and metal–air batteries. Herein, a single-atom Fe-embedded hierarchical porous hollow carbon fiber catalyst (Fe SAC/HCNF) is reported for ORR. The hollow channels and the porous structure of the fibers facilitate the exposure of single-atom active sites, and offer multidimensional mass transfer pathways to promote the transport of reactants, thus significantly enhancing catalytic performance. Additionally, the abundant micropores exert spatial confinement, which is beneficial for preventing the aggregation of single atoms. Leveraging its unique structural advantages, the Fe SAC/HCNF catalyst demonstrates outstanding ORR activity with low metal loading, boasting a high half-wave potential of 0.905 V, a substantial double-layer capacitance ( C dl ) of 41.1 mF cm −2 , and a notable kinetic current density of 45.2 mA cm −2 in alkaline media. Furthermore, the liquid Zn–air battery (ZAB) using Fe SAC/HCNF catalyst as the air cathode exhibits excellent battery performance and long-term cycling durability nearly 600 h. And the flexible quasi-solid-state ZAB can be stably cycled in various flat/bent states, which is promising for applications in flexible electronic devices. Graphical

Psoriasis represents a chronic inflammatory skin disease occurring globally. We investigated the role of plasma exosomal microRNA (miR)- 148a- 3p and its target gene Bim in psoriasis. Plasma exosomes (Exos) and CD4 + T cells were extracted from psoriatic patients. miR- 148a- 3p expression in Exos and CD4 + T cells of psoriatic patients, the proportions of CD4 + T cell subsets, and the contents of anti-inflammatory/pro-inflammatory factors were determined by RT-qPCR, flow cytometry and ELISA. The correlation between plasma exosomal miR- 148a- 3p and CD4 + T cell subsets in psoriatic patients was analyzed by Pearson’s analysis. The psoriatic mouse was treated with Exos/antagomir miR- 148a- 3p. Histopathological changes in the skin were observed. The CD4 + T cell subset levels, serum cytokine contents and miR- 148a- 3p expression in the blood were measured. The miR- 148a- 3p-Bim targeted binding relationship was predicted and verified by Starbase database and dual-luciferase assay. The Bim expression in psoriatic mice was determined. Psoriatic patients had highly-expressed miR- 148a- 3p in both Exos and CD4 + T cells, and abnormal CD4 + T cell subsets and cytokine levels. Plasma exosomal miR- 148a- 3p was correlated with the CD4 + T cell subsets in psoriatic patients. Exos caused down-regulated miR- 148a- 3p level in skin tissues of mouse, regulated CD4 + T cell function and aggravated the symptoms in psoriatic mice. miR- 148a- 3p repression partially reversed the role of Exos in CD4 + T cell function and psoriasis-like symptoms. Exos-carried miR- 148a- 3p targeted Bim in CD4 + T cells of psoriatic mice. Plasma exosomal miR- 148a- 3p targeted Bim to affect the dysfunction of CD4 + T cells in psoriatic mice, thereby aggravating the psoriasis-like symptoms.

Idiopathic pulmonary fibrosis (IPF), characterized by fibroblast activation and collagen deposition, is a progressive lung disease that lacks effective interventions. Ubiquitin-specific peptidase 10 (USP10) acts as a multifunctional player in inflammatory response and progression of cancers, the effect on pulmonary fibrosis is unknown. Here, we demonstrated downregulated expression of USP10 in fibrotic lung tissues of IPF patients. In the current study, lung tissues were collected at the end of weeks 1, 2, or 3 post bleomycin (BLM)-intratracheal delivery. Consistently, USP10 expression levels were reduced after BLM challenge in a time-dependent manner. Mice treated with lentivirus overexpressing USP10 exhibited mitigative lung injury and reduced collagen deposition. USP10 overexpression enhanced autophagy in BLM-treated mouse lungs. Interestingly, the protective effect of USP10 was attenuated as the pulmonary autophagy flux was blocked by autophagy inhibitor 3-methyladenine (3-MA). Primary human and mouse lung fibroblasts were treated with pro-fibrotic TGF-β1 to verify the role of USP10 in vitro. Mechanically, the deubiquitinating enzyme USP10 interacted with Sirtuin 6 (Sirt6) and inhibited its degradation. Furthermore, USP10 overexpression inhibited the activation of Sirt6-mediated AKT/mTOR pathway in both lung tissues and fibroblasts. Our findings suggest that USP10 might attenuate pulmonary fibrosis through the promotion of Sirt6/AKT/mTOR-mediated autophagy. These data prioritize USP10 as a therapeutic target for treating IPF.
