Summary: Considering the significant risk of H2S gas to human life, research on H2S gas sensors has gained considerable interest. This study presents the fabrication of CuO/ZnO multifaceted nanostructures through heat treatment of Cu2+/ZIF-8 impregnation precursors, and evaluates their microstructure and gas sensing characteristics using various characterization techniques. The hollow CuO/ZnO nanostructures demonstrated high gas response, quick response and recovery times, low detection limit, good humidity resistance, and high selectivity towards H2S gas, which can be attributed to their porous hollow nanostructures, p-CuO/n-ZnO heterojunctions, and the spillover effect between CuO and H2S.

Summary: Designing heterostructure materials at the nanoscale is a well-known method to enhance gas sensing performance. In this study, ZnO/SnO2 heterostructures were grown on alumina substrates using the ultrasonic spray pyrolysis method. The results showed that the sensitivity of the sensor to H2S gas can be altered by changing the zinc chloride content in the precursor, and the heterostructures with a 5:1 ratio of ZnCl2 to SnCl2·2H(2)O exhibited the highest response. The gas sensing mechanism of the ZnO/SnO2 heterostructures was analyzed and attributed to the formation of the heterostructure between ZnO and SnO2.

Summary: Novel flower-like ZnO nanomaterials were synthesized by a solvothermal method without using a template or surfactant. The resulting ZnO flowers had a hierarchical structure composed of nanorods that grew radially from the center. Gas sensors based on these ZnO flowers showed high sensitivity to H2S gas with a response of 157.3 and excellent selectivity at a low temperature of 92 degrees C. The porous hierarchical architecture of the ZnO flowers facilitated rapid gas adsorption and enhanced charge transfer, resulting in superior gas-sensing capabilities. The XPS technique was used to investigate the surface state of the ZnO flowers before and after exposure to H2S gas, and a possible sensing mechanism was proposed.

Summary: xCuO-(1-x)Fe2O3 composite nanofibers for gas-sensing applications were investigated using on-chip electrospinning. The composite nanofibers showed improved sensor response compared to single metal oxides. The optimal composition of 0.5CuO-0.5Fe2O3 formed a complex oxide of copper ferrite (CuFe2O4) and exhibited the highest response to H2S and NO2 gases. The gas-sensing performance was attributed to the nanograin-based structure, formation of CuFe2O4 oxide, and heterojunctions in the composite nanofibers.

Summary: This study aimed to determine the prognostic significance of cuproptosis-associated lncRNAs in soft tissue sarcomas (STSs) and their relationship to the tumor immune microenvironment. The study identified a signature of 5 cuproptosis-associated lncRNAs, classified STS patients into high-risk and low-risk groups, and found that high-risk patients had a worse prognosis. A nomogram combining clinical characteristics and risk scores was constructed and showed reliable predictive power. Functional enrichment and tumor immune microenvironment analysis suggested that high-risk STSs tend to be immunologically sensitive tumors.
