Constructing robust nucleation sites with an ultrafine size in a confined environment is essential toward simultaneously achieving superior utilization, high capacity, and long-term durability Na metal-based energy storage, yet remains largely unexplored. Here, we report previously unexplored design of spatially atomic Sn hollow carbon spheres for homogeneous dendrite-free growth. The designed architecture maximizes prevents agglomeration, mitigates volume variation, allows complete...
Sodium metal batteries hold great promise for energy-dense and low-cost energy storage technology but are severely impeded by catastrophic dendrite issue. State-of-the-art strategies including sodiophilic seeding/hosting interphase design manifest success on suppression, while neglecting unavoidable interphase-depleted Na + before plating, which poses excessive use, sacrificed output voltage ultimately reduced density. We here demonstrate that elaborate-designed fluorinated porous framework...
Abstract Tackling the interfacial loss in emerged perovskite‐based solar cells (PSCs) to address synchronously carrier dynamics and environmental stability, has been of fundamental viable importance, while technological hurdles remain not only creating such mediator, but subsequent embedding active layer. This article reports a strategy hydrophobic fluorinated‐gold‐clusters (FGCs) for highly efficient stable PSCs. The p‐type semiconducting feature enables FGC mediator improve by reducing...
Abstract Potassium‐ion batteries (PIBs) have emerged as a compelling complement to existing lithium‐ion for large‐scale energy storage applications, due the resource‐abundance of potassium, low standard redox potential and high conductivity K + ‐based electrolytes. Rapid progress has been made in identifying suitable carbon anode materials address sluggish kinetics huge volume variation problems caused by large‐size . However, most research into focused on structural design performance...
Pure-bromide quasi-2D perovskite (PBQ-2DP) promises high-performance light-emitting diodes (LEDs), while a challenge remains on control over its n-phase distribution for bright true-blue emission. Present work addresses the through exploring passivation molecule of amino acid with reinforced binding energy, which generates narrow preferentially at n = 3 true blue emission 478 nm. Consequently, peak external quantum efficiency 5.52% and record brightness 512 cd m–2 are achieved PBQ-2DP-based...

Metal-halide perovskite nanocrystals (NCs) are one of the most promising emitters for application display and nanolight sources. The full width at half-maximum (FWHM) photoluminescence (PL) emission is essential color purity, which however remains a difficulty to further reduce FWHM NCs room temperature. Here, we show quasi-sphere with narrow PL deep-blue wavelength ∼430 nm; its reaches ∼11 nm temperature, owing monodispersion in size distribution as well symmetric morphology releasing fine...
Abstract Formamidinium (FA)‐based perovskite promises high power conversion efficiency in photovoltaics while it faces awkward spontaneous yellow phase transition even at ambient conditions. This has spurred intensive efforts which leave a formidable challenge on robust anchoring of the soft lattice. Present work pioneers rational design interfacial ionic‐bonding between halogen‐terminated nano‐MXenes and for effective retarding lattice instability FA‐based perovskites. The heterointerface...
Establishing covalent heterointerfaces with face-to-face contact is promising for advanced energy storage, while challenge remains on how to inhibit the anisotropic growth of nucleated crystals matrix.

Novel three-dimensional (3D) continuously graded phononic crystals (CGPCs) have been designed, and fabricated by 3D printing. Each of the CGPCs is an entity instead a combination several other samples, porosity distribution CGPC along incident direction nearly linear. The sound absorption characteristics were experimentally investigated compared with those uniform (UPCs) discretely stepped (DSPCs). Experimental results show that demonstrate excellent performance because their structures....
Reducing the crystal size of perovskites to strong quantum confinement regime is an effective way realize blue luminescence for light-emitting applications. However, challenges remain in directly constraining growth during film preparation achieve three-dimensional confinement, and widely used long-chain ligands may bring difficulties charge transport unfavorably affect device performance. Herein, we report a novel strategy fabricating strongly confined blue-emitting perovskite...
Mn2+ ions doped CsPbCl3 perovskite nanocrystals (NCs) exhibit superiority of spin-associated optical and electrical properties. However, precisely controlling the doping concentration, location, mono-distribution in large-micro-size host is a formidable challenge. Here, micro size crystals (MCs) are reported with uniform by self-assembly NCs. The electron-phonon coupling strength enhanced self-assembled MCs, which remarkably accelerates PL decay room temperature. Furthermore, phonon-involved...

Specifically, theoretical model for LSTs, verified by direct numerical simulations (DNSs), reveals that much smaller pore diameter larger layer thickness material needed to gain high...
Abstract Quasi‐2D perovskite exhibits excellent luminescence properties for highly efficient light‐emitting diodes (PeLEDs). However, the lattice degradation and crystalline phase transition induced by water limit PeLED's development application commercialization. It is demonstrated that organic additives effectively reduce defect density, while bonding strength of these organics becomes weak under high electric field Joule heat in an operating PeLED. Thus, alternative additive forming...
