Summary: This study presents the preparation of multifunctional microwave absorbers with robust hydrophobicity and enhanced wave absorption. By electrospinning and in-situ annealing method, carbon nanofibers (CNFs) inlaid with Ni/NiO and SiO2 nanoparticles were prepared. The results showed that at an annealing temperature of 550 °C, Ni/NiO/SiO2/CNFs achieved the optimal reflection loss (RL) at 16.6 GHz and had a large effective absorption bandwidth (EAB). The introduction of nano SiO2 into Ni/NiO/CNFs improved the complex permittivity and widened the EAB. Additionally, the prepared membranes exhibited robust hydrophobicity. These nanofibers hold promise for multifunction wave absorbers.

Summary: Novel synthesis techniques were employed to fabricate SiO2@SnO2 core-shell microbelts and hollow SnO2 microbelts, which were sensitized with platinum nanoparticles to enhance their acetone detection capability. The sensitized SnO2 microbelts showed significantly higher response to 2 ppm acetone and faster response time compared to pristine SnO2 microbelts. The sensor based on sensitized SnO2 microbelts also exhibited promising stability and repeatability toward acetone exposure in a humid environment.

Summary: In recent years, MXenes and its precursor MAX phases have been extensively studied in electrochemical research. In this study, a core-shell structured compound, Ti3C2@Ti2SnC/CNFs (MXene@TSC/C), was successfully prepared as an anode material for lithium-ion batteries using the electrospinning method. The compound exhibited a specific capacity of 288.9 mAh·g-1 at a current density of 0.4 A g-1 after 300 cycles, with a capacity retention rate of 105.4% in rate performance tests. These enhanced performances were attributed to the core-shell structured CNFs and Ti3C2 MXenes. This work provides a novel approach to improving the electrochemical properties of MXene and MAX phases, with further exploration expected.
