Anionic chemistry modulation represents a promising avenue to enhance the electrochemical performance and unlock versatile applications in cutting‐edge energy storage devices. Herein, we propose a methodology that involves anionic chemistry of carbonate anions to tailor the electrochemical oxidation‐reduction reactions of bismuth (Bi) electrodes, where the conversion energy barrier for Bi (0) to Bi (III) has been significantly reduced, endowing anionic full batteries with enhanced electrochemical kinetics and chemical self‐charging property. The elaborately designed batteries with an air‐switch demonstrate rapid self‐recharging capabilities, recovering over 80 % of the electrochemical full charging capacity within a remarkably short timeframe of 1 hour and achieving a cumulative self‐charging capacity of 5 Ah g−1. The aqueous self‐charging battery strategy induced by carbonate anion, as proposed in this study, holds the potential for extending to various anionic systems, including seawater‐based Cl− ion batteries. This work offers a universal framework for advancing next‐generation multi‐functional power sources. [ABSTRACT FROM AUTHOR]

Covalent organic frameworks (COFs) are porous organic materials with well‐defined and uniform structure. The material is an excellent candidate as a solid adsorbent for iodine adsorption. In the present study, we report the synthesis of COF with porphyrin moiety, TF‐TA‐COF, by solvothermal reaction, which was characterized by XRD, solid‐state 13C NMR, IR, TGA, and nitrogen adsorption‐desorption analysis. TF‐TA‐COF showed a high specific surface area of 443 m2 g−1, and exhibited good adsorption performance for iodine vapor, with an adsorption capacity of 2.74 g g−1. XPS and Raman spectrum indicated that a hybrid of physisorption and chemisorption took place between host COF and iodine molecules. The electric properties of iodine‐loaded TF‐TA‐COF were also studied. After doped with iodine, the conductivity of the material increased by more than 5 orders of magnitude. The photoconductivity of I2‐doped COF was also studied and TF‐TA‐COF showed doping‐enhanced photocurrent generation. [ABSTRACT FROM AUTHOR]

Objective To screen for the key genes involved in the development of ovarian cancer (OV), analyze the immune cell infiltration and construct a risk model, so as to provide evidence for the early diagnosis, treatment and prognosis evaluation of OV patients. Methods The GSE18520 and GSE6008 datasets were analyzed for differentially expressed genes (DEGs) using the GEO2R data analysis tool, and a Venn diagram was generated. Then, DEGs were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and protein-protein interaction (PPI) networks, as well as mutations, expression and prognosis analysis to identify key genes. Next, a risk model was constructed and immune cell infiltration analysis of key genes was performed. Finally, ovarian cancer tissues were collected as the experimental group, and adjacent normal tissues were collected as the control group. The expression of claudin 4 (CLDN4) mRNA and protein levels were detected using real-time quantitative PCR (RT-qPCR) and Western-blot, and the results were compared between the two groups. Results CLDN4 was identified as a key gene in the development of OV. As its expression increased, the prognosis risk of OV patients worsened, which unfavorably impacted their overall survival (OS). A significant positive correlation was found between CLDN4 and dendritic cell (DC) in the OV microenvironment, and high expression of DCs was significantly associated with better OS in OV patients. The mRNA and protein expression levels of CLDN4 were significantly increased in OV tissues, with statistically significant differences. Conclusion CLDN4 is a key gene in the development of OV, and may serve as a potential biomarker and immunotherapy target for OV.

Based on transversely isotropic theory, a finite element model for three-dimensional solid-liquid coupling defect repair of articular cartilage was established. By studying stress state of host cartilage near the restoration interface, we identified deformation type of cartilage and discussed the cause of restoration interface cracking. The results showed that the host cartilage surface node near the restoration interface underwent compression deformation in the condition of surface layer defect repair. When the middle layer, deep layer or full-thickness defect were repaired, the node underwent tensile deformation. At this point, the radial dimension of cartilage increased, which might cause restoration interface cracking. If elastic modulus of the tissue engineered cartilage (TEC) was lower (0.1 MPa, 0.3 MPa), the host cartilage surface layer and middle layer mainly underwent tensile deformation. While elastic modulus of TEC was higher (0.6 MPa, 0.9 MPa), each layer of host cartilage underwent compression deformation. Therefore, the elastic modulus of TEC could be increased properly for full-thickness defect repair. This article provides a new idea for evaluating the effect of cartilage tissue engineering repair, and has a certain guiding significance for clinical practice.
