NaBiTiO (NBT) ceramic is the promising dielectric material for energy storage devices due to its high maximum polarizability and temperature stability. However, its low breakdown strength limits its application. Here, we prepared 0-3 type composite 0.45NaBiTiO-0.55SrBiTiO/ wt % AlN (NBT-SBT/AlN) to increase the breakdown strength. The effects of the various AlN contents on the phase composition, microstructures, dielectric, and energy storage properties of NBT-SBT were systematically discussed. The result showed that the enhanced energy storage properties were obtained by introducing AlN particles. The NBT-SBT/6AlN composite ceramics showed a high breakdown strength of 360 kV/cm, large energy density of 5.53 J/cm, and energy efficiency of 90%. Meanwhile, the excellent frequency (10-500 Hz) and temperature stability (25-125 °C) were exhibited with the fluctuation of energy storage within 9% and energy efficiency more than 87%, suggesting that the 0-3 composite NBT-SBT/AlN is a candidate dielectric material for the dielectric energy storage.

Incorporating non-electrochemically active elements (such as Zn and Mg) into the framework of active components can enhance structural stability, leading to improved cycling performance. However, limited research has been conducted on the impact of varying doping concentrations. In this study, we conducted a comprehensive analysis of how different levels of Mg doping in Co(OH) affect the supercapacitor performance.

The multicentered bonds present in planar borophene lead to a more complex structure and richer chemical properties. Herein, we use first-principles calculations to investigate the electronic, mechanical, and superconducting properties of various borophene polymorphs, focusing on the newly synthesized β and β phases. Notably, in order to balance and optimize the electron filling of the valence bond orbitals, the planar borophene structure is composed of a mixture of triangular lattices and hexagonal holes with multicentered bonding, which further enhances the stability of the structure and possesses a rare polymorphic property.

The triboelectric nanogenerator (TENG) has been proved to be a very promising marine energy harvesting technology. Herein, we have developed a high-performance triboelectric nanogenerator (SD-TENG) with low friction, high durability, swing-induced counter-rotating motion mechanism (SICRMM) and dual potential energy storage and release strategy (DPESRS). The unique counter-rotating motion mechanism enabled SD-TENG to convert the external linear and swing motion energy into rotation motion energy of the inner and outer cylinders, and then converted it into a controllable power output.

Importance: The brain and adipose tissue interact metabolically, and if there is a problem with the energy metabolism of the brain, it cannot maintain the energy balance with the adipose tissue. Therefore, when adenylate kinase 5 (), which regulates energy metabolism in the brain, is knocked out, problems with lipid metabolism may occur.
Objective: We aimed to elucidate the metabolic function and phenotype of , a gene with an unknown function in metabolism.
