Perpendicular Magnetic Anisotropy
In article number 2308724, Xi Shen, Xiufeng Han, Richeng Yu, and co‐workers proposed a strategy for enhancing perpendicular magnetic anisotropy in yttrium iron garnet (YIG) films with only a tiny lattice mismatch by slight oxygen deficiency, which theoretically originates from the reduction of saturation magnetization and the increase of magnetostriction coefficient...
Passivating the electronic defects of metal halide perovskite is regarded as an effective way to improve the power conversion efficiency (PCE) of perovskite solar cells (PVSCs). Here, a series of dipeptide molecules with abundant ─C═O, ─O─ and ─NH functional groups as defects passivators for perovskite films are employed. These dipeptide molecules are utilized to treat the surface of prototype methyl...

Herein, two natural biocompatible compounds, namely thioctic acid (TA) and malic acid (MA), are selected to prepare...
In the evolving landscape of water treatment, membrane technology has ascended to an instrumental role, underscored by its unmatched efficacy and ubiquity. Diverse synthesis and modification techniques are employed to fabricate state‐of‐the‐art liquid separation membranes. Click reactions, distinguished by their rapid kinetics, minimal byproduct generation, and simple reaction condition, emerge as...
The poor efficiency and low immunogenicity of photodynamic therapy (PDT), and the immunosuppressive tumor microenvironment (ITM) lead to tumor recurrence and metastasis. In this work, TCPP‐TER‐Zn@RSV nanosheets (TZR NSs) that co‐assembled from the endoplasmic reticulum (ER)‐targeting photosensitizer TCPP‐TER‐Zn nanosheets (TZ NSs for short) and the autophagy promoting and indoleamine‐(2, 3)‐dioxygenase...
The safety, low cost, and high power density of aqueous Zn‐based devices (AZDs) appeal to large‐scale energy storage. Yet, the presence of hydrogen evolution reaction (HER) and chemical corrosion in the AZDs leads to local OH− concentration increasement and the formation of ZnxSOy(OH)z•nH2O (ZHS) by‐products at the Zn/electrolyte interface, causing instability and irreversibility of the Zn‐anodes...
Knee replacement surgery confronts challenges including patient dissatisfaction and the necessity for secondary procedures. A key requirement lies in dual‐modal measurement of force and temperature of artificial joints during postoperative monitoring. Here, a novel non‐toxic near‐infrared (NIR) phosphor Sr3Sn2O7:Nd, Yb, is designed to realize the dual‐modal measurement. The strategy is to entail phonon‐assisted...
