Multifunctional MnFeO/TiO/TiCT composites based on in-situ grown TiO for efficient microwave absorption, high hydrophobicity, and heat dissipation properties.

Despite the fact that the 2D structure TiCT with abundant defects and functional groups contributes to the high microwave absorption (MA) performance, it is difficulty to improve the strength and bandwidth by pursuing higher conductivity or loading more groups due to the limitation of intrinsic properties. Therefore, it is important to ingeniously design efficient TiCT based MA composites assembling the features of abundant surface groups, good dispersibility, multiple composition, and precise structure. Inspired by the fact that TiCT contains thermodynamically metastable marginal Ti atoms, TiO nanoparticles can be grown in-situ on TiCT nanosheets uniformly and increase the spacing of TiCT layers, and then MnFeO nanoparticles are introduced into the layers of TiCT by electrostatic self-assembly method for optimized impedance matching.

Isolation and characterization of Vibrio parahaemolyticus bacteriophage vB_VpaS_PG07.

A novel bacteriophage vB_VpaS_PG07 (hereafter designated PG07) that infects Vibrio parahaemolyticus was isolated. The bacteriophage was examined by transmission electron microscopy, and the result showed that PG07 belonged to family Siphoviridae, with an isometric polyhedral head (80 nm in diameter) and a long tail (175 nm in length). The one-step growth curve showed that the latent period and burst size were 10 min and 60 PFUs/infected cell, respectively.
