It is a long-standing challenge in the fabrication of single-phase VO 2 films at low temperature on Si substrate or glass substrate due to their thermodynamic phase-instability and the polymorphic structures. Recently, the demand for high-quality thin films deposited at low temperature is strongly pushed by their applications on devices and smart windows. Thermochromic films of VO 2 , as well as multilayer films of VO 2 /ZnO and VO 2 /TiO 2 /ZnO, were made by magnetron sputtering method and characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), UV–visible-NIR spectrophotometer, (scanning) transmission electron microscopy ((S)TEM) and Electron energy loss spectroscopy (EELS). Films with high crystalline degree VO 2 single crystal phase were obtained at a fairly low temperature of 300 °C without subsequent annealing by embedding ZnO and TiO 2 layers between VO 2 and substrates. It is demonstrated that VO 2 /TiO 2 /ZnO films could display higher luminous transmittance and better semiconductor to metal transition (SMT) performance. Our data can serve a promising point for industrial production with high degree of crystallinity at a low temperature. [ABSTRACT FROM AUTHOR]

Microviridae is a family of phages with circular ssDNA genomes and they are widely found in various environments and organisms. In this study, virome techniques were employed to explore potential members of Microviridae in a poultry slaughterhouse, leading to the identification of 98 novel and complete microvirus genomes. Using a similarity clustering network classification approach, these viruses were found to belong to at least 6 new subfamilies within Microviridae and 3 higher-level taxonomic units. Genome size, GC content and genome structure of these new taxa showed evident regularities, validating the rationality of our classification method. Our method can divide microviruses into about 45 additional detailed clusters, which may serve as a new standard for classifying Microviridae members. Furthermore, by addressing the scarcity of host information for microviruses, the current study significantly broadened their host range and discovered over 20 possible new hosts, including important pathogenic bacteria such as Helicobacter pylori and Vibrio cholerae , as well as different taxa demonstrated different host specificities. The findings of this study effectively expand the diversity of the Microviridae family, providing new insights for their classification and identification. Additionally, it offers a novel perspective for monitoring and controlling pathogenic microorganisms in poultry slaughterhouse environments., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Xie, Lin, Sun, Zhu, Liu, Liu, Cao, Pan, Qiu, Yuan, Liang, Jiang and Yuan.)
