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: In this study, La-doped diamond-like carbon (DLC) films were prepared using magnetron co-sputtering technique. The effects of La content on the mechanical properties and surface wettability of the DLC films were investigated. The results showed that the doping of La resulted in smoother and locally graphitized DLC films, and revealed a different relationship between residual stress and sp3-C fraction compared to hardness and elastic modulus. Additionally, air-exposed DLC films underwent surface reactions with air molecules and volatile organic compounds (VOCs), leading to rapid color changes and affecting the surface wettability. The doping-induced enhancements in VOCs adsorption and sp2-C fraction contributed to the transition from hydrophilicity to hydrophobicity of the DLC film. This study provides insights into the complex microstructures and properties of La-doped DLC films, and offers a feasible method for preparing high-performance DLC films with low residual stress and adjustable surface wettability.

Summary: Inspired by spider silk's ability to collect water from a humid environment, a superwetting poly(vinylidene fluoride) (PVDF) membrane with spindle-knotted structured fibers was prepared using the electrospinning method followed by oxygen plasma etching treatment. The membrane showed excellent separation efficiency for various oil-in-water emulsions, as the combination of special wettability property and spindle-knot structure facilitated quick accumulation of the emulsified oil droplets on the membrane surface. A model explaining this accumulation was developed and verified using an artificial fiber with micron-sized spindle-knot structure.

Summary: In this contribution, we present a model of oil-water separation based on the movement of liquid droplets on cone-shaped structures inspired by spider silk. The forces acting on the droplets are derived from first principles of physics, and their directional movement in another liquid medium is thoroughly investigated and modeled. The resulting model predicts the droplet motion dependence on time and system defining parameters, which provides a possibility for the design and preparation of bionic structures in droplet transport phenomena.
