Summary: This study fabricated a unique nanorod-assembled actinomorphic-flower-like microsphere structured film of tantalum (Ta)-doped titanium dioxide. The Ta-doped TiO2 actinomorphic-flower-like microsphere (TAFM) was prepared via the solution immersion method. Characterization of the samples using various techniques showed that the rutile-phased TAFM sample had finer nanorods with enhanced electrical properties. It was also found that the TAFM exhibited high electron trap density and showed promising results as a resistive-type sensing film for a humidity sensor.

Summary: Novel TiO2//Bi2WO6 Janus nanofibers (JNFs) were successfully fabricated via a facile conjugated electrospinning, and used to manufacture gas sensors with high selectivity for ethanol gas molecules and fast response and recovery speed. The unique heterostructures formed by TiO2 and Bi2WO6 on both sides of Janus nanofibers through close interfacial contact promote charge transfer and enhance gas sensing properties of the JNFs. The gas sensor based on this unique heterostructure has great potential in the field of gas detection.
