Among various methods of developing hydrogen energy, electrocatalytic water splitting for hydrogen production is one of the approaches to achieve the goal of zero carbon emissions. It is of great significance to develop highly active and stable catalysts to improve the efficiency of hydrogen production. In recent years, the construction of nanoscale heterostructure electrocatalysts through interface engineering can not only overcome the shortcomings of single-component materials to effectively improve their electrocatalytic efficiency and stability but also adjust the intrinsic activity or design synergistic interfaces to improve catalytic performance.

Herein, a dual-strategy is developed to boost the Na-storage performance of the Fe/Mn-based layered oxide cathode by copper (Cu) doping and nanoengineering. The P2-NaCuFeMnO cathode material synthesized by electrospinning exhibits the pearl necklace-like hierarchical nanostructures assembled by nanograins with sizes of 50-150 nm.

Despite much progress in this regard, there still remains challenges in dynamic liquid droplet manipulation with fast response, no loss and anti-contamination. Herein, a strategy to achieve dynamic droplet manipulation and transportation on the electric field adaptive superhydrophobic elastomer surface is demonstrated.

We performed extensive first-principles studies on the magnetic ordering and Jahn-Teller (JT) distortion of spinel LiMnO, a promising candidate for cathode materials in Li-ion batteries. We find that the ground state of LiMnO is an anti-ferromagnetic (AFM) orthorhombic spinel structure, where AFM Mn layers and FM Mn layers alternate along the [001] direction and the 90° Mn-O-Mn in the Mn-(001) planes are AFM coupling, forming an indirect Kramers-Anderson superexchange. The coplanar Mn ions maximize the JT distortion and the AFM magnetic orderings further strengthen the interaction between Mn cations and O anions, making the structure stable.
