Bandgap Calculation and Experimental Analysis of Piezoelectric Phononic Crystals Based on Partial Differential Equations.

Focusing on the bending wave characteristic of plate-shell structures, this paper derives the complex band curve of piezoelectric phononic crystal based on the equilibrium differential equation in the plane stress state using COMSOL PDE 6.2. To ascertain the computational model's accuracy, the computed complex band curve is then cross-validated against real band curves obtained through coupling simulations.

Nakazawaea tricholomae f.a., sp. nov., a Novel Ascomycetous Yeast Species Isolated from Two Mushroom Species in China.

Two yeast strains designated as 20-27-1 and 20-28 were isolated from the fruiting bodies of Tricholoma gambosum and Marasmius maximus, respectively, which were collected in Wudaogou, Weichang county, Chengde area, Hebei Province, China. The multi-locus analysis of the sequences of the rDNA ITS, D1/D2 LSU, and SSU regions, together with partial sequences of two protein-coding genes RPB1 and TEF1 indicates that the two strains are closely related to Nakazawaea ernobii and Nakazawaea holstii, showing the similarity values of 99.3-98.

Preparation of LiV(PO) as cathode material for aqueous zinc ion batteries by a hydrothermal assisted sol-gel method and its properties.

To alleviate the depletion of lithium resources and improve battery capacity and rate capacity, the development of aqueous zinc-ion batteries (AZIBs) is crucial. The open channels monoclinic structure LiV(PO) is conducive to the transfer and diffusion of guest ions, making it a promising cathode material for AZIBs. Therefore, in this study, nanoneedles and particles LiV(PO) cathode materials for AZIBs were prepared by a hydrothermal assisted sol-gel method, and the effect of synthesized pH values was studied.
