ABSTRACT The design and synthesis of highly efficient electrochemical sensors are pivotal to electrochemical conversion technologies. This study successfully synthesized a composite material comprising two‐dimensional (2D) conductive MXene and nickel‐based metal–organic framework (Ni‐MOF) by stirring at room temperature. By adjusting the amounts of dimethylformamide (DMF) and M…

ABSTRACT Alkali metal (Li, Na, and K) batteries (AMBs) have attracted widespread attention in recent years because of their high theoretical specific capacity and attractive energy density. However, they still suffer from uncontrollable dendrite growth and sluggish conductivity during cycling, which lead to security issues and inferior cycling performance. Fortunately, the intr…

ABSTRACT A central challenge in alkaline water electrolysis is the development of hydrogen evolution reaction (HER) electrocatalysts that simultaneously maintain high activity and structural stability at industrial current densities. Hydroxide‐based supports that facilitate water dissociation are particularly susceptible to over‐reduction and structural degradation under strong…

ABSTRACT Brazing of Ti ₂ AlNb alloy is a pivotal technique for new generation aero‐engine lightweight structures, yet developing novel filler metal and achieving the extraordinary performance of titanium alloy brazed joints remains challenging. Here, this study designed an innovative filler metal (Ti _{70 ‐ x} Zr _x Cu ₁₅ Ni ₁₅ ) and developed inspired coupled…

ABSTRACT Efficient removal of volatile organic compounds (VOCs) in confined spaces is crucial for environments such as spacecraft and deep‐sea submarines. Metal modification is an effective strategy to enhance the light absorption capacity of titanium dioxide (TiO ₂ ) and suppress the recombination of photogenerated charge carriers. However, the synergistic mechanisms betwee…

ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in nanosized lithium‐free transition…

ABSTRACT Solar‐blind ultraviolet (UV) photodetectors (SBPDs) play a critical role in applications including UV communication and fire warning systems. Gallium oxide (Ga ₂ O ₃ ) has emerged as a promising material due to its wide bandgap and low cost, but suffers from high dark current and slow response speed caused by oxygen vacancy ( V _O ) defects. This work proposes …

ABSTRACT Metallic cerium (Ce), a widely used surrogate for actinide metals, enables mechanistic studies of reactions in complex gas environments under controlled and safer laboratory conditions. Here, the oxidation behavior of Ce in H ₂ O‐N ₂ mixed atmospheres was investigated from 200°C to 350°C using in situ thermogravimetry–mass spectrometry, in situ X‐ray diffraction,…

ABSTRACT The regeneration of osteoporotic bone defects is severely hampered by compromised endogenous healing capacity, demanding advanced strategies that actively orchestrate pro‐osteogenic microenvironments. Here, we report an integrated, self‐powered osteo‐regenerative system that uniquely leverages a dual ultrasound‐responsive piezoelectric mechanism for synergistic therapy…

ABSTRACT Composites of metal–organic frameworks (MOFs)/two‐dimensional transition metal carbides/nitrides (MXene) have been widely recognized as promising electrode materials for advanced electrochemical energy storage systems due to their synergistic structural advantages and tunable electrochemical properties. Through comprehensive analysis of the latest MOF/MXene composite s…

ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li ⁺ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic outer layer, is suitable …

ABSTRACT Rationally designing an electrocatalyst to achieve stable and efficient urea oxidation reaction (UOR) is crucial but still challenging, especially for ampere‐level application. Herein, Mn and Fe dual‐doped Ni _0.85 Se (Mn/Fe–Ni _0.85 Se) catalyst is synthesized via a facile and scalable electrodeposition and followed by selenization. Thanks to the dual introduction…

ABSTRACT A facile coprecipitation‐pyrolysis strategy was employed to fabricate Cu/Co nanoparticles (NPs) embedded in nitrogen‐doped carbon matrices (Cu/Co@N‐C) through the carbonization of CuCo‐MOF precursors. Moreover, monometallic counterparts of Cu@N‐C and Co@N‐C were also prepared via carbonization of bimetallic CuZn‐MOF and CoZn‐MOF, respectively. Electrochemical tests con…
