Artificial solid electrolyte interphase in organic solutions is effective and facile for long‐cycling aqueous zinc ion batteries. However, the specific effects on different ionic environments have not been thoroughly investigated. Herein, pyromellitic acid (PA) are employed as organic ligand to coordinate with Zn2+ under various ionic environments. The connection between the ionic environment and...
Efficient bifunctional hydrogen electrocatalysis, encompassing both hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR), is of paramount significance in advancing hydrogen‐based societies. While non‐precious‐metal‐based catalysts, particularly those based on nickel (Ni), are essential for alkaline HER/HOR, their intrinsic catalytic activity often falls short of expectations. Herein,...
Structure engineering of magnetic‐dielectric multi‐components is emerging as an effective approach for presuming high‐performance electromagnetic (EM) absorption, but still faces bottlenecks due to the ambiguous regulation mechanism of surface morphology. Here, a novel wrinkled surface structure is tailored on the ZnFe2O4 microsphere via a spray‐pyrolysis induced Kirkendall diffusion effect, the conductivity...
Interface engineering attracted tremendous attention owing to its remarkable ability to impede dendrite growth and side reactions in aqueous zinc‐ion batteries. Artificial interface layers composed of crystalline materials have been extensively employed to stabilize the Zn anode. However, the diffusion kinetics of Zn2+ in highly crystalline materials are hindered by steric effects from the lattice,...

Under the high current density, the excessive strong adsorption of H* intermediates and H2 accumulation the catalysts are the major obstacle to the industrial application of hydrogen evolation reaction (HER) catalysts. Herein, through experimental exploration, it is found that the superaerophobic Nitrogen (N)‐doped carbon material can promote the rapid release of H2 and provide H* desorption site...
Pd‐based electrocatalysts are the most effective catalysts for ethylene glycol oxidation reaction (EGOR), while the disadvantages of poor stability, low resistance to neutrophilic, and low catalytic activity seriously hamper the development of direct ethylene glycol fuel cells (DEGFCs). In this work, defect‐riched PdCoZn nanosheets (D‐PdCoZn NSs) with ultrathin 2D NSs and porous structures are fabricated...
Fast recombination dynamics of photocarriers competing with sluggish surface photohole oxidation kinetics severely restricts the photoelectrochemical (PEC) conversion efficiency of photoanode.

In this study, a three‐step strategy including electrochemical cathode deposition, self‐oxidation, and hydrothermal reaction is applied to prepare the LiMn2O4 nanosheets on carbon cloth (LMOns@CC) as a binder‐free cathode in a hybrid capacitive deionization (CDI) cell for selectively extracting lithium from salt‐lake brine. The binder‐free LMOns@CC electrodes are constructed from dozens of 2D LiMn...
Droplet well‐controlled directional motion being an essential function has attracted much interest in academic and industrial applications, such as self‐cleaning, micro‐/nano‐electro‐mechanical systems, drug delivery, and heat‐transferring. Conventional understanding has it that a droplet impacted on an anisotropic surface tends to bounce along the microstructural direction, which is mainly dictated...
Droplet Motion
Conventional understanding is that droplet motion on the anisotropic surface tends to bounce along the microstructural direction, mainly dictated by surface properties. In article number 2305568, Lei Wang and co‐workers present that the droplet motion on the anisotropic surface can be switched by initial impacting velocity. The droplet shows successively a backward, vertical, and forward...
The fabrication of perovskite light‐emitting diodes (PeLEDs) with vacuum deposition shows great potential and commercial value in realizing large‐area display panel manufacturing. However, the electroluminescence (EL) performance of vacuum‐deposited PeLEDs still lags behind the counterparts fabricated by solution process, especially in the field of blue PeLEDs. Here, the fabrication of high‐quality...

Intervertebral Disc Degeneration
A biomimetic peptide (OAFF) binds to C‐X‐C motif chemokine receptor 1 (CXCR1) and forms fibrous networks on nucleus pulposus stem cells (NPSCs) for mimicking extracellular matrix formation, which induces NPSCs quiescence and ultimately overcomes obstacle in intradiscal injection therapy.

Traditional current‐driven spintronics is limited by localized heating issues and large energy consumption, restricting their data storage density and operation speed. Meanwhile, voltage‐driven spintronics with much lower energy dissipation also suffers from charge‐induced interfacial corrosion.
