Abstract The availability of an ever‐expanding portfolio 2D materials with rich internal degrees freedom (spin, excitonic, valley, sublattice, and layer pseudospin) together the unique ability to tailor heterostructures made by in a precisely chosen stacking sequence relative crystallographic alignments, offers unprecedented platform for realizing design. However, breadth multi‐dimensional parameter space massive data sets involved is emblematic complex, resource‐intensive experimentation, which not only challenges current state art but also renders exhaustive sampling untenable. To this end, machine learning, very powerful data‐driven approach subset artificial intelligence, potential game‐changer, enabling cheaper – yet more efficient alternative traditional computational strategies. It new paradigm autonomous experimentation accelerated discovery machine‐assisted design functional heterostructures.

Aqueous Zn-metal batteries have attracted increasing interest for large-scale energy storage owing to their outstanding merits in terms of safety, cost and production. However, they constantly suffer from inadequate density poor cycling stability due the presence zinc ions fully hydrated solvation state. Thus, designing dehydrated structure can effectively address current drawbacks aqueous batteries. In this case, considering lack studies focused on strategies dehydration ions, herein, we present a systematic comprehensive review deepen understanding zinc-ion regulation. Two fundamental design principles component regulation pre-desolvation are summarized environment formation interfacial desolvation behavior. Subsequently, specific strategy based distinct carefully discussed, including preparation methods, working mechanisms, analysis approaches performance improvements. Finally, general summary issues addressed using strategies, four critical aspects promote presented as an outlook, involving updating (de)solvation theories, revealing evolution, enhancing techniques developing functional materials. We believe that will not only stimulate more creativity optimizing electrolytes but also provide valuable insights into other battery systems.

Abstract Research on organic–inorganic hybrid materials (OIHMs) has experienced explosive growth in the past decades. The diversity of organic components allows for introduction various spatial scales, functional groups, and polarities, while inorganic provide higher hardness, heat resistance, stability, their flexible combination facilitates formation diverse structures. Furthermore, simple cost‐effective synthesis methods, such as room temperature solution processes mechanochemical techniques, enable precise control over materials' properties at different thus achieving adjustable structure–performance relationships. This review will discuss recent research progress OIHMs within field optoelectronics related optoelectronic device applications. According to dimension nature interface, this divides into four structural categories. ongoing revealed applications fields solar cells, light‐emitting devices, detectors, memristors. As an outlook, potential perovskite 0D metal halide materials, which are currently most studied, enhancing performance stability is discussed.

Lower dimensional or 2D halide perovskites, with their versatile structural and functional properties, are known to improve the performance room temperature stability of perovskite solar cells. One would expect perovskites be more resistant ion migration compared 3D counterparts because presence bulky organic cations. However, recent findings show that indeed is prevalent in similar perovskites. Halide manifests itself segregation under photoirradiation as well exchange between physically paired films different ions. Besides migration, cation spacer cations A-site also seen when 2D/3D subjected light thermal stress. It important recognize importance while incorporating cells other optoelectronic devices, it can detrimental for achieving streamlined long-term stability. This Perspective discusses reports on operational conditions (at elevated given built-in bias) presents a few mitigating strategies.
