Summary: In this study, a high-rate and ultralong-life Mg-Li hybrid battery based on a dual-phase TiO2 cathode was reported, exhibiting superior pseudocapacitive properties, specific capacities, rate performance, cycling stability, and coulombic efficiency. The outstanding electrochemical performance of the dual-phase TiO2 nanosheet cathode was attributed to the enhanced pseudocapacitive Mg/Li-ion diffusion through nanointerfaces between anatase and bronze crystallites. The approach demonstrated in this study could be further exploited for the development of other high-performance electrodes for advanced Mg-Li hybrid batteries.

Summary: This study investigates the surface wrinkling and post-wrinkling bifurcation using a micropattern configuration at a 3-dimensional level. The presence of the pattern allows for the regulation of local strain energy distribution, enabling a programmable transition from wrinkles to post-wrinkling morphologies. Finite element analysis reveals that the post-wrinkling bifurcation is caused by stress concentration at the edge of the micropattern. This finding has important implications for designing future smart surfaces, sensors, and actuators.

Summary: Terephthalic acid reformed Al/Zn metal organic nanoflake functionalized with trie-thylamine (T-AlZn) exhibits remarkable performance in removing trace lead (II) ions (Pb2+), with an adsorption equilibrium reached within 35 min and a removal rate ≥ 97%. After four regenerations, the decline in removal rates of T-AlZn for Pb2+ is only 16.73%. The adsorption of T-AlZn for Pb2+ follows the Langmuir isotherms model and pseudo-second-order dynamics model, with the utmost adsorption competence of 215.27 mg g-1. T-AlZn adsorbent shows a bright prospect in the adsorption for Pb2+ and is a considerable candidate in the disposal of industrial sewage.
